Aberystwyth Town's "home" match against Carmarthen A on Monday 13th February at the Emlyn Cafe, Tanygroes, was a convivial affair like the old days of the Dyfed League, with the University team's match against Carmarthen B taking place on adjacent tables. On Board 1, Murray Smith reached a rook ending a pawn up against Ewan Ferguson's Grand Prix Attack in the Sicilian Defence. White looked able to hold for a while, but once the rooks came off the win followed quickly. In the only non-Sicilian of the match, a Scotch Four Knights, Luis Sanchez also had an extra pawn and the initiative, but Black's position looked solid until a blunder which should have cost him material. White went wrong in the complications that followed but clinched the win anyway after another error by his opponent.Peter Windows was facing the sharp Smith-Morra Gambit for the first time on Board 3, but White was too generous with his pawns and the attack didn't materialize: by the time White had recovered some material the Black passed pawns were unstoppable. I missed a chance for an advantage with my Closed Variation of the Sicilian against Grenville Brazener and the game was level until I was able to break in the centre. Both players were down to their last few minutes, with the top three boards having already finished when the team captain, Murray, came up and asked if we knew that the clocks weren't giving us the intended 20-seconds per move increment; they're new and we hadn't set them properly. Fortunately for me, I was now in control of the game if not the technology, and mate followed shortly. It was a good night for the Aber teams, less so for Carmarthen, with 4-0 whitewashes in both matches.

Our second match in the new Dyfed League was played against Cardigan at the familiar venue of the Emlyn Cafe, Tanygroes, on Tuesday 31st January. There were some new players involved but the rivalry between the two clubs and the setting in which it's played out remains the same. On top board, Murray Smith had a cagey draw in the Queen's Indian with Howard Williams; the tension dissipated early, leaving a level ending. Peter Windows's Sicilian against Ben Brewer was complex and double-edged; in the end, with both players short of time, White's kingside attack prevailed. Sam Holman dominated the game in a Ruy Lopez against Andre Benn; White's space advantage soon led to both material gains and a crushing attack. Samuel Raybone got back on terms in a Caro-Kann against Awne Osinga after dropping a piece early on, only to succumb in a difficult rook and pawn ending. A close match ended in a 2½-1½ wind for Cardigan.
</p>
<p>
Meanwhile we have held their first AGM of the new era. We have elected the following officers: Matthew Francis (Chair); Samuel Raybone (Secretary); Peter Windows (Treasurer); Murray Smith / Luis Sanchez (Joint Team Captains). We are currently holding our club nights upstairs at The Scholars pub in Aberystwyth on Tuesdays from 6.30 onwards (all welcome).

The first match of the reincarnated Dyfed League took place at Aberystwyth University between the Town and University teams
on Tuesday 10th January. Unfortunately the University team defaulted on top board, so Murray Smith didn't get a game. On second board
Luis Ortiz Sanchez was in fine form, trading off against Toby Carter's Pirc to reach a superior ending, which he played with relentless accuracy to claim the win. Peter Windows played the comparatively rare Owen's Defence against Toby Bates and never quite managed to equalize. Black's pieces were tied up defending the kingside, and his attempt to gain counterplay on the queenside only opened lines for the White pieces to come in for the kill. Tom Gunn weakened Filip Zurek's kingside in a Queen's Gambit Accepted, and Black missed the best defence, allowing a quick mating attack. A winning start for the Town team, 3-1 including the defaulted game.

As part of the continuing preparations for the return of the Dyfed League in January, members of Aberystwyth Town Chess Club too part in some individual online friendly matches against similarly rated players from other clubs on Wednesday 30 November. In the strongest match-up, Murray Smith conjured up a strong attack against Lluis Navarro in the usually quiet Exchange Variation of the Caro-Kann. In a high-quality encounter, White's pressure eventually led to the gain of a pawn and a winning ending. Peter Windows walked into a fierce attack from Mark Paffard with his English Opening. Black's imaginative play culminated anticlimactically in a missed mate, and Peter was able to force a draw an exchange down. Against a player only identified as Josh, I sprung a familiar trap with my Vienna Gambit, and was relieved when he not only fell into it, but missed my error that could have let him right back into the game, after which the win was comfortable. Sam Holman got a strong position with advanced passed pawns against Filip Zurek, in a Sicilian Defence, but blundered a rook. Samuel Raybone was another player who fell into an opening trap, in a Caro-Kann against Ewan Ferguson; it didn't lose material as White only regained a gambited pawn, but Samuel lost the right to castle and the defence of his position ultimately proved too difficult. Mixed fortunes for the Club, and bad luck for Luis Sanchez and Tom Gunn, whose opponents didn't show up.

The second of our pair of friendly matches against the University team was played in the Hugh Owen Building of the University on Thursday 24th November. Playing his first match for the Club, Luis Ortiz Sanchez had Black on top board againt his compatriot Lluis Navarro. Appropriately the opening was a Catalan, though I suppose a Spanish would have been still more so. White took advantage Black's loose queenside to penetrate the position and was soon able to work his way over to the kingside and force mate. In another Catalan (by transposition from the English), Peter Windows won a piece in the opening and was always winning but had to be patient in the face of some awkward Black counterplay before it finally fizzeld out. Sam Holman's King's Indian soon became blocked; Harry Fox's position looked better, but he had no way through. Samuel Raybone reached a level ending against Patrick Bourne in a Queen's Gambit Declined. Black dropped a pawn and White missed a chance of a winning advantage but the eventual ending with rook and pawn against rook was a clear draw. Once again the result was a friendly 2-2.

The last couple of years have been difficult for chess in the area. Not only were we forced to move to online competitions because of the Covid pandemic, but three popular players and energetic supporters of Dyfed chess have sadly died: FM Iolo Jones, organizer of the Dyfed League and one of the pioneers of modern Welsh chess, Tony Haigh, Treasurer of the Dyfed Chess Association, and David Pinch, who kept chess going by organizing online matches and torunaments when over-the-board play was impossible. They are all much missed.
</p>
<p>
For Aberystwyth Town Chess Club, the problems were compounded by factors which had been apparent even before the pandemic, the erosion of our membership and the lack of a suitable place to meet. Two valued members, Rudy and Julie van Kemenade moved away from the area earlier this year, leaving us down to four active players, Adam Watkin-Jones, Tom Gunn, Sam Holman and myself - and, now Adam is unable to play for the time being due to pressure of work. In the circumstances, I thought it would be necessary to dissolve <a href="https://www.welshchessunion.uk/aberystwyth-chess-club-history/">this historic club</a>.
</p>
<p>
But, unexpectedly, things have begun to revive, both for the club and Dyfed. Several new players have moved into the Aberystwyth area, and at the same time FM Howard Williams, the Secretary of the Dyfed Chess Association, has begun the process of reviving the Dyfed League, which is due to start as a hybrid online / OTB event in January. As we look for a permanent meeting place, the Town club has been generously welcomed by our sister club at the University to their Wednesday afternoon sessions in the Arts Centre bar, and we have celebrated having enough players for a team by organizing some friendly matches.
</p>
<p>
The first of these was played between the University and the Town at the Arts Centre bar on Thursday 17 November. On top board for the Town, Peter Windows couldn't make progress with his kingside attack against Toby Carter's Pirc, and a misjudged exchange left him down in material, with a lost game. I built a defensive stronghold with my Caro-Kann against Toby Bates, and was eventually able to break out with a winning counterattack. Tom Gunn turned the win of a piece into a speculative queen sacrifice in an irregular Queen's Pawn Game against Harry Fox, and gained a decisive advantage in the ensuing complications. Samuel Rayburn also played a Caro-Kann against Rufaro Chisiwenga but lost a pawn to a neat tactic and was unable to get back into the game. A 2-2 draw seemed an appopriate result for this celebratory friendly.

It was not really to be expected that Aberystwyth would continue the exceptional results of the last couple of matches, but we have undoubtedly been competing well in the Open Section of the Welsh Chess Union Online League this time, and came close to drawing our latest match, against Pontyfenni. Rudy van Kemenade's attacked on the kingside in a Bird's Opening against Mark Adams, but a flurry of exchanges left Black with the initiative enabling him to grab several pawns, leading to a winning endgame. Adam Watkin-Jones's Owen's Defence gave him a good position against Ian Jones, but he went wrong in the middlegame allowing an attack that should have been decisive. White's miscalculation gave Adam a piece, but stopping the enemy pawns was a challenge, and he eventually resigned in a position where a draw was still in fact possible. I emerged an exchange up against John Waterfield from a series of complications in a Modern Defence, but then hung a rook. Black was now a piece up, but again the ending needed some care, and his return error gifted me a lucky draw. Sam Holman's kingside attack against Anthony Hughes's English Opening was a bit premature. White was able to counter in the centre, and when he won a piece with a pawn fork the end followed quickly. A 3½-½ defeat could have been an impressive 2-2 draw if Adam and I had taken our chances.
</p>
<p>
Tom Gunn's Queen's Gambit game against Bence Szakmany in the U-1800 match between Cardigan and North Cardiff Panthers was yet another example of a difficult ending between an extra piece and extra pawns. This time it was Tom with the extra piece and after long manoeuvring he managed to bring home the win.

After my last post suggesting that Aberystwyth were putting up an unexpectedly good fight in the Open Section of the Welsh Chess Union Online League, our match against Morriston on Thursday 9th December confirmed our good form. On top board, an interesting Budapest Gambit game was in prospect when Rudy van Kemande's opponent, Moss McCarthy, dropped a rook and resigned at once. It turned out that both players were too hasty: White could have trapped Black's queen after the capture, forcing her to give herself up for the second rook, leaving an unclear position, while Rudy had overlooked a winning alternative. Adam Watkin-Jones won a piece with a fork in an irregular opening against Chris Howells, who was unable to find any counterplay, and lost further material before resigning. I have recently taken up the Caro-Kann, inspired by Levy Rozman's Gotham Chess YouTube Channel: of his recommended line against the Advance Variation, he says, "You WILL win White's centre pawns, often!" and that's exactly what happened in my game against Francisco Marin, next time I'll remember to take both of them, but one was enough on this occasion. Sam Holman's game against Duncan Williams followed a line played several times in the recent World Championship match between Carlsen and Nepomniachtchi. Black won a pawn in the centre but overlooked White's threats on the kingside and Sam broke through to give mate. 4-0 to Aber was an outstanding result.

Fears that Aberystwyth would be totally outclassed by the very strong teams in the Open Section of the Welsh Chess Union Online League haven't materialized in the matches so far. After our excellent win the previous week, we put up a fighting performance against White Knights on Thursday 25 November. Rudy van Kemenade's King's Indian Attack against Alan Young led to a blocked position in which the White pieces were getting in each other's way. Black had the initiative but couldn't find a way through with time getting short and settled for a draw by repetition. Adam Watkin-Jones played rather passively against Allan Pleasants in another hypermodern-type opening, and was soon tied down to the defence of his queenside against White's advancing pawns, resigning when the attack broke through. I took advantage of Adam May's vulnerable kingside with an unexpected tactic in a Caro-Kann Two Knights; there was only a draw there with best defence, but he didn't find the right moves and his position collapsed. Tom Gunn was comfortable in a Queen's Indian against Thomasz Miga till he allowed White's previously blocked central pawns to roll forward, when they proved to be unstoppable without material loss. A 2½-1½ defeat was a respectable result for Aber.
</p>
<p>
Playing for Cardigan against Peter Smith of De La Beche Rooks, Aberystwyth's Sam Holman managed to win his opponent's queen in a King's Indian Defence, but by that time White's attack in the centre and on the kingside was overwhelming, and mate soon followed.

Aberystwyth scored an excellent result in WCU Online League on Thursay 11 November, beating the top-ranked team of Pontyfenni. On top board, Rudy van Kemenade played the little-known Schallopp Defence against John Waterfield's King's Gambit (at least, it is little-known by me, and on the evidence of this game looks well worth exploring) and a sharp game was initiated, which ended abruptly when White overlooked Black's threat of mate in one. A great result for the team but disappointing from a neutral point of view as the game could have been fascinating. Adam Watkin-Jones had a spatial advantage in a blocked position against Ian Jones's Philidor by transposition; when Black's king was denuded of pawns White looked to have winning chances, but exchanges brought about a difficult queen ending and Adam settled for the draw in view of the team's favourable position in the match. Julie van Kemenade had a solid and active position with her King's Indian against Alan Keene, with chances for both sides, when White, under time pressure, gave away a piece. Sam Holman's game against Justin Morgans was a typical cut-and-thrus Najdorf Sicilian with the players attacking on opposite wings and both missing opportunities to win before White took control in the queen ending. The match finished as a 3½-½ win to Aber.
<p>
</p>
Aber's Tom Gunn also had a fine result playing for Steynton against Richard Williams of White Knights. Dominating the board against Black's Old Indian Defence, Tom gradually focused all his pieces on the king to force a mating attack.

After our defeat in the first round of the Open Section of the WCU Online League, Aberystwyth did much better against Morriston on Thursday 4th November. Rudy van Kemenade's Bird's Opening brought him no middlegame advantage against Peter Bevan, and they arrived at the ending equal. Apparently Black was distracted by the football at this stage, and went wrong, dropping a pawn and accepting an unfavourable exchange that left him with a weak bishop against a strong knight, after which Rudy was able to win comfortably. Adam Watkin-Jones's Pirc against Chris Howells quickly transposed into a King's Indian - I'm not sure whether this was intended or not, but Black's position seemed awkward and he was two pawns down when he resigned, perhaps a bit prematurely, given the opposite-coloured bishops. Against Francisco Marin Marin in a Closed Sicilian, my kingside attack was faster than Black's counter on the queenside and in the centre, and the push of the f-pawn broke open his king's position. My queen's bishop remained on its home square all game. Sam Holman's game against Duncan Williams was another King's Indian, in which Black had a dynamic position and good chances in the early stages. After locking his bishop in, though, he came under pressure, and eventually dropped a rook. A 2-2 draw was a good result for Aber.
</p>
<p>
In games for other teams, Tom got a good win against Keith Briggs's Slav Defence, exploiting Black's queenside weakness to get a passed pawn, then winning with a nice tactic, while Sam, in another King's-Indian-like opening again had a dynamic position against Gwyn Evans, but after both sides made mistakes in the ending the game was drawn.

Although the club has suspended face-to-face chess for the year, members are continuing to take part in online events. The first round of the Dyfed Closed Online tournament recently took place and it will run until January. The WCU online leagues have also resumed, and we are greatly helped here by the fact that Rudy and Julie van Kemenade are still available to play for us. We are taking part in the formidably strong Open section, with Rudy as our captain and top board. We don't have enough available members to field an under-1800 team as well, so Tom Gunn and Sam Holman, as well as taking their turns in the Open team, will be playing for Steynton at the lower level.
</p>
<p>
Our first match in the Open was against White Knights. Rudy's Petroff against Bill Hewitt reached an unbalaced middlegame where Black had two pieces for a rook. The advantage was with Rudy, who managed to convert the imbalance to a clear extra knight, only to get it trapped in the endgame. After that he was still a pawn up in the queen ending but could only draw. I spent most of the game trying to shore up the weaknesses in my position against Allan Pleasants's Modern Defence, but was beginning to feel more comfortable as time started to run out for both of us. I then thought I saw an opportunity to go on the attack, but it was an illusion and my position quickly collapsed. Julie took too long getting her counter-attack started against Jason Garcia in a King's Indian Defence. White's centre was very dominant, and, as she tried to mix things up, she walked into a pawn fork and resigned at once. Tom's Queen's Gambit gave Tomasz Miga the two bishops and an imposing phalanx of pawns on the queenside, which ultimately proved impossible to stop. White Knights won the match 3½-½.

Tony Haigh, who played for Cardigan, died of cancer on 27 February. As his <a href="https://www.tivysideadvertiser.co.uk/news/19157433.obituary-tony-haigh-brythdir-mawr-newport/" target="_blank">obituar</a>y in the Tivy-Side Advertiser reveals, he was a valued member of the community at Brithdir Mawr, Newport, Pembrokeshire, and a man of many skills and interests, including plumbing, gardening and astronomy as well as chess. He represented Cardigan in the European Club Cup in 2013. A strong endgame player with a positional style, Tony was regularly near the top of the ratings in Dyfed; I played him often, never beating him, but always enjoying the struggle with a player who was as sporting and likeable as he was skillful.

<a href="https://www.welshchessunion.uk/obituaries/fm-iolo-ceredig-jones-rip/" target="_blank">Iolo Ceredig Jones</a>, who died in September after a short illness, was a legendary figure in Welsh chess. Along with his father, T. Llew Jones, he was the author of the only Welsh-language chess manual, <i>A chwaraei di Wyddbwyll</i>? (‘Do you play <i>gwyddbwyll</i>?’, the latter the name of a historic Welsh boardgame which the Joneses adopted for chess). He competed for Wales in several Olympiads, earning a gold medal in 1990 and the FIDE Master title in 1998, and was later active in international seniors' chess. In this long career he played some of the most illustrious grandmasters of the age, including Planinc, Romanishin and Ghitescu, and once drew with the great Lajos Portisch.In his local area, he organized the annual Dyfed Closed tournament, always a convivial event, and the Dyfed League, where he attended every match, whether he was playing or not, a benign and humorous presence in the background. As a player, he liked to steer the game into quiet positions, even allowing himself to get cramped in the knowledge that, with his formidable technique and vision he would wear his opponent down eventually. Needless to say I lost every game I played against him, and I remember one in particular where we were dead level deep into the endgame with both of us running out of time: Iolo was perfectly calm throughout, knowing he could outplay me from any position, and he chuckled afterwards as he showed me where I had gone wrong. Welsh chess will not be the same without him.

In other news, Aberystwyth Chess Club is saying goodbye to two exceptional players and friends, Rudy and Julie van Kemenade, who are moving out of the area. I plan to post a tribute to them shortly. With the Covid crisis far from over and our membership at a low ebb following this latest reduction in our numbers, we are suspending our activities till next year.Matthew Francishttp://www.blogger.com/profile/13561893228695759475noreply@blogger.com0tag:blogger.com,1999:blog-1210278545182458788.post-59325656614729151072021-06-15T14:50:00.001-07:002021-06-15T14:50:37.701-07:00End of Season<html>

Aberystwyth played our last match of the season on Tuesday 8 June against White Knights. It's been fun playing in the Dyfed Online League and, as here, in the Welsh Chess Union Online Open, though we were certainly outclassed in the latter with the exception of our captain and top board, Rudy van Kemenade. In this last match he duly delivered our only win, with a high-class performance against Allan Pleasants, winning a rook ending with an extra pawn where all the pawns were on the same side - a sure-fire draw for most of us, but Rudy kept up the pressure and induced his opponent's losing error. I was out of my depth against Adam May on the Black side of a Catalan, an opening I know little about, and after a couple of inaccuracies my position was hopeless. Tom Gunn tried a promising-looking combination against Tomasz Miga in a Queen's Gambit, giving up two pieces for a rook and two pawns, but it backfired, leavinng Black's bishope pair dominant, and Tom was soon defending passively against a crushing kingside attack. Finally, Sam Holman attacked without completing his development against Guto Neave's English Opening, and his exchange combination didn't work out, losing a piece. He fought on, surviving longer than Boards 2 and 3, but the odds were always against him. A 3-1 win to White Knights to finsh the season.

Aberystwyth faced some of our most formidable opponents yet in the form of Newport and Friends in the Welsh Chess Union Online League Open Section on Tuesday 11 May. Part of the problem in dealing with such a challenge is coontinuing to believe in yourself; all four of us in the Aber team started well enough but were unable to last the distance. On top board Rudy van Kemenade had achieved a comfortable opening against FM Grzegorz Toczek by transposing into a McCutcheon French when a miscalculation cost him a pawn. The closed postion then began to work against him, and his uncastled king became a target. Adam Watkin-Jones's unorthodox English against Ernest Gibiec arrived at a Stonewall formation, with both players having strong central knights. Moving his own knight away from its outpost proved fatal, as White's position collapsed quickly. Having declined Adam Rakos's Wing Gambit against my Siclian, I had to work fast to undermine his extended pawn centre before his kingside attack could get going, but was too defensive. Tom Gunn arrived via a Semi-Slav route at the sort of solid but dynamic queen's pawn game he likes and seemed at least equal against Chris Boyd when he dropped a pawn; again things turned against him quickly after that. A 4-0 win for Newport and Friends could have been so much better for Aber. By way of consolation I finish with a good win for Aber's Sam Holman, moonlighting for Cardigan against a strong opponent, David Pinch of Steynton A, in the Under 1800 section.

Another double post. Aberystwyth entered the last round of the Dyfed Online League on Tuesday 20 April needing a win against Steynton A to secure the championship. Top board Rudy van Kemenade probably knows the Petroff better than anyone, at least below grandmaster level, but Martin Jones had prepared well, and a complex theoretical struggle ensued. Black's two bishops and better pawns gave him an edge, but the result was far from clear until White blundered, losing an exchange. Adam Watkin-Jones dominated throughout in a Closed Siclian against Mark Paffard, who unwisely opened the position without having castled. The middlegame had only just started when White forced a decisive win of material. On Board 4, Tom Gunn was a pawn up for much of the game against Scott Hammett's Hippopotamus, but went a pawn down as the game transitioned to an ending. It was still difficult for Black, and Tom had a chance of saving the game at the very last moment. Everything then depended on my Board 3 game against Rob Lovegrove, which was the last to finish. After a good opening with my O'Kelly Sicilian, I allowed White to break in the centre and win a pawn, and spent most of the game trying in vain to undermine his dominant queenside pawns. But as time began to run out, both of us made errors - first White allowed a knight fork, then I returned the favour, then, in trying to clinch the win, he let me escape with my extra material. The 3-1 win to Aber gained us the title. Thanks to David Pinch for organizing a very successful and enjoyable league, and, as always, to Rudy for his analysis and captaincy.

Next week we were in action again, this time in the Welsh Chess Union Open Online against Pontyfenni. Rudy's aggressive early h4 against John Waterfield's Grunfeld only led to delayed development, with White's knight stuck on g1 until well into the middlegame, but Black wasn't able to take advantage and the game simplified to a drawn king-and-pawn ending. Adam got a level position against Ian Jones's Glek Four Knights, but went wrong in the complex rook ending which followed. They say all rook endings are drawn, and he missed a chance to draw this one, just before the end. Tom seemed slightly worse in a Dutch against Anthony Hughes, but the position was very blocked and soon became impassable. The game of the round was on Board 4, where Sam Holman's Sicilian came under fierce attack from Justin Morgans. Both players missed chances in the complications but White emerged an exchange and a pawn ahead. He was well behind on the clock, though, and had problems dealing with Sam's active minor pieces. Eventually he dropped a bishop, but Sam found it equally difficult to finish him off, till White made one last blunder and resigned. The result was a 2-2 draw.

This blog has been rather behindhand recently, so here are two match reports. In a match played mainly on Wednesday 7th April, Aberystwyth took on the University's B team. On top board, Adam Watkin-Jones's Bird's Opening against Marcus Perry did not yield any early advantage. With queens, dark-squared bishops and pawns on the board and time running out, Adam looked to complicate things, but it didn't quite work out and he eventually accepted the draw. I missed the win of a piece in my O'Kelly Sicilian against Toby Bates, instead losing a pawn, though the position was more or less level. Both of us went wrong in the ending, but it was still level when White blundered, losing a rook. Tom Gunn had pressure against Harry Fox's backward c-pawn in a Queen's Pawn Game, and Black's attempt to free himself was a tactical error losing a piece, after which Tom had no problems in the ending. In another Queen's Pawn Game, Sam Holman missed a number of chances to win a piece, but retained the upper hand in a minor piece ending thanks to his powerful bishops. A 3½-½ win to the town side, but it could have been very different.
</p>
<p>
Aber's opposition in the WCU Online League is formidable, and on Tuesday 13th April we took on Morriston Alekhine. Adam's Queen's Gambit Declined against Moss McCarthy developed into a battle between Black's dangerous-looking queenside passed pawns and White's attack against the kingside. White never really looked to be breaking through, but managed to exert enough pressure to get a draw. I found myself in a Queen's Gambit also, more or less by accident as I misplayed my English against Peter Bevan and couldn't think of anything better after 2...d5. Nevertheless my position was OK until I grabbed a pawn and ended up having to try to defend against Black's doubled rooks on my second rank, which was never going to end well. Tom also looked comfortable against Chris Howells's King's Indian Attack until he missed the threat posed by the White queen, which finished the game very suddenly. Sam got in trouble in a Ruy Lopez against Duncan Williams allowing a favourable version of the Marshall Attack against his Ruy Lopez, which would have been highly dangerous even for experienced players in this line. He soon lost a rook in the ensuing tactics. The result was a win to Morriston by 3½-½.

An Aberystwyth team missing our Board 4 took on Cardiff in the second round of the second Welsh Chess Union Online League on Tuesday 30th March. The opening of Rudy van Kemenade's game against Tom Brown was the Hyper-Accelerated Dragon Variation of the Sicilian Defence, which has to be a contender for most exotic opening name in chess. The game itself was less interesting, though, as a wholesale exchange of pieces in a position with symmetrical pawns led to an early draw. Adam Watkin-Jones played a noteworthy opening variation, too, a line of the Scandinavian which was under a cloud for years after a devastating win by Fischer, but is now apparently rehabilitated. Certainly it led to a good position for Adam, whose strong fianchettoed bishop and pressure on the White centre gave him the early advantage. The pressure continued after there were just heavy pieces and pawns left, and Sam Jukes eventually blundered in time trouble. I found myself facing a fierce attack from Jake Hurley against my English opening, having castled too soon. I have never like to do too much thinking at the beginning of the game, and my defence soon fell apart. With the default on Board 4, Aber lost the match 2½-1½.

Aberystwyth were facing more familiar opposition on Thursday 25th March when we played Aberystwyth University's A team in a hard-fought match. On top board Rudy van Kemenade got an edge against Owain Davies's Vienna Game when a brief flurry of middle-game tactics left the White pawns more vulnerable. Nevertheless there was still much work to be done in a hihg-quality game before Black secured the point. Adam Watkin-Jones played cautiously against Matthew Horhey, holding back the centre pawns and fianchettoing both bishops. Nevertheless Black managed to set an unexpected trap in the opening, to win the game after only a dozen moves. Tom Gunn's Sicilian against Kieran Judge led, as so often, to a position with the players attacking each other's kings on opposite sides of the board - unusually for this opening, though, it was Black castled on the queenside and White on the kingside. When the promising White attack ground to a halt, Black was able to break through on the other wing. Sam Holman's Austrian Attack against Gabriela Griffiths's Pirc ripped open the kingside in the approved fashion, but she defended staunchly, belying her lower rating, and the game was even for a long time. Black would probably have held out for a draw but for a mistake in time trouble. The result was 3-1 to the town side.

With a limited pool of players to draw on, Aberystwyth has entered the Open section of the Welsh Chess Union Online League this session, so that our strongest player, Rudy van Kemenade, can take part. It is going to prove a tough challenge, as the match against 3½ Men on Tuesday 16th March showed. The disarming name belies a formidably strong team, with masters on the top two boards. Against FM Jonathan Blackburn Rudy deviated from his normal line in the Nc3 variation of the Petroff to avoid opening preparation, and soon found himself under kingside pressure. He was holding his own till an error meant that he must drop a piece - games can end very suddenly at this level. Adam Watkin-Jones's pawn sacrifice in a London System against CM Tim Kett didn't produce the hoped-for advantage: he was soon going backwards, and resigned on losing material. My French against Hugo Fowler produced a horribly cramped position, with White pressure all over the board. Losing a pawn did nothing to free the position and I limped into a hopeless ending before resigning. Tom Gunn looked to be doing OK against Duncan MacDonald's dangerous Blumenfeld Gambit, but his complicated combination was miscalculated, leaving him behind on material and with Black dominating the board. A 4-0 defeat was a painful introduction to this section of the league.

Four Aberystwyth players entered the Dyfed Rapidplay competition for March on Tuesday 9th. Rudy van Kemenade, as in the February competition, came first with a perfect score of 5/5. Tom Gunn scored 2½/5, I scored 2/4 (plus a full-point bye), and Sam Holman had a disappointing tournament with 0/4 and a full-point bye. Steynton's David Pinch and Scott Hammett were second and third respectively.

The opening can be, as the word implies, merely a way of getting into the game; at other times the struggle can begin with the very first moves The match between Aberystwyth and Steynton B in the Dyfed Online League on Tuesday 2nd March saw some heavyweight openings which dictated the course of what followed. Rudy van Kemenade, anticipating a prepared variation from Paul Orton, chose the Bishop's Opening, but in fact the game soon took on the character of a Ruy Lopez with the centre blocked and the players attacking on the flanks. The Ruy has retained its popularity because it makes for a complex battle, and both players made mistakes according to the engines, but when Rudy was able to push through his f5 advance, the Black kingside was broken and the attack crashed through. In my game against Jonathan Jones, I found myself facing an opening I had never even heard of, the sharp Orthoschnapps Gambit against the French Defence. I did my best to stick to strategic principles and somehow reached a middle game with an extra pawn without too many tactical fireworks. After further exchanges, only that extra pawn was left and it was enough to win the ending. The games on Boards 3 and 4 were both examples of the King's Indian, another opening known for its complexity. Tom Gunn, taking a break from his usual Colle System, worked up a strong kingside attack against John Miller's passive position. When he won a knight, it looked all over, but with an exposed king, and queens on the board, there were many chances for perpetual check, and he was lucky when Black went wrong and allowed him to finish the game off. In the other King's Indian, both players seemed to be attacking on the kingside. Sam Holman's attack was the more principled, since he had pressure on the White centre and his advanced pawns on the g and h files had gained space. Gwyn Evans tried to take advantage of the open f file by doubling his rooks, only to lose the exchange to a pin, and when he overlooked a threat to his queen the game was over.

<p>
Even in the online format, matches between Aberystwyth and Cardigan have something of the feel of an Old Firm rivalry, and the match in the Dyfed Online League on Tuesday 23rd February was no exception. Top boards Rudy van Kemenade and Howard Williams have had many fierce fights over the years, so it was only to be expected that this latest meeting would be a complex struggle. In a sharp King's Indian, Rudy went a pawn down and had to seek piece activity in compensation. Eventually the only way out was to give up a piece with the aim of eliminating all White's pawns, and, with Howard short of time and having to defend against mate threats, this was enough to earn Rudy the draw. In contrast, Adam Watkin-Jones's game against Ben Brewer was over quickly, as he overlooked a threat to his h pawn in a Slav, and resigned in disgust, though there was still plenty of play left. Once again I had some positional problems with my Dutch Stonewall, this time against Gareth Williams. When he offered a piece for a couple of pawns and an unbalanced position, I should probably have taken it, but I hadn't seen very far into the sequence and passed it up, after which the game settled into equality. Tom Gunn's Greek gift sacrifice in his Colle System wasn't sound, but Joshua Brewer didn't find the best defence, and the White attack broke though for the win. The match was drawn, 2-2.
