Rudy in Llandudno

Rudy van Kemenade had another good tournament in the British Chess Championships in Llandudno this summer, finishing 3rd= in the Over 65 section. His only defeat was in the first round, in which, he says, he managed to beat himself.

So Near and Yet No Car

The clubs of the Dyfed League are spread out over a wide geographical area, and their players often live some way from the clubs. Add to that the fact that an unusual number of chess players seem to be non-drivers (me, for example)and it becomes clear why matches are often hard to arrange. Several clubs have had transport difficulties this year, Aberystyth included, with the result that not all the matches have been played by the end of the season. This is particularly hard on the A team, who competed extremely well this year, and could have won the title if all their matches had been played. On the last day of the season, Wednesday 31 May, we consoled ourselves with a 4-0 victory over Carmarthen at the Emlyn Cafe, Tanygroes.

On top board, Rudy van Kemenade played the unusual Chigorin Defence against Gerry Heap, and an odd-looking position was soon reached, with the White king on f1 instead of safely castled. This worked out badly for Gerry as he lost the exchange to a discovered check and was unable to find any compensation. The second-board game was also over quickly. Adam Watkin-Jones developed sensibly against David Buttell's Sicilian, and Black's attempt to start complications backfired, leaving him a rook down. Adam Robinson celebrated his last game for the club by opening 1...a5 against 1.e4. Paul Orton refused to be provoked, and, despite going a pawn down, looked very comfortable for most of the middle game, missing a win before compounding the error with a final blunder. I had a space advantage with my London System against Robert Narayan-Taylor, but could make no headway. Feeling my position about to fall apart, I went in for a risky sacrifice; with both players desperately short of time, I was losing the ending when Black slipped up and allowed me a lucky win - not the first time that's happened to me this year.A 4-0 win was some consolation to Aber for the season that got away.

Home Comfort

The Brynamlwg Tavern will be closed next Tuesday, 18 April, so there will be no chess that night.

Aberystwyth A continued their strong run in this year's Dyfed League with a home win against Gwyddbwyll.com at the Brynamlwg Tavern on Tuesday 4 April. On top board, Rudy van Kemenade won a pawn against Iwan Griffiths in an Italian Game, and Black's two bishops were not enough compensation; Rudy won on time, but was dominating the ending anyway. Adam Watkin-Jones, playing a Sicilian Defence, had reached a level position with only major pieces and pawns left, when Owen Llywelyn blundered, dropping his otherwise defensible b-pawn and letting the Black pieces in for a quick win. Ian Finlay was under pressure in a Queen's Gambit against Tegwyn Jones; it looked as if he could hold, but he fell into a nasty trap, and his position abruptly collapsed. Sam Holman won an exchange early on against Emyr Llywelyn, but it was his kingside pawns, charging down the board, that really did the damage; White's attempts at a mate on the other wing never looked realistic. The match finished 3-1 to Aber.If only we could get some transport for our away matches, this could be a good year for the team.

Cleanish Sweep



Aberystwyth was not quite able to raise the eight players required for the A versus B match on Tuesday 21 March, so the match took place on three boards only. Both James Corrigan and Rudy van Kemenade enjoy complex tactical positions, so it was no surprise when James, playing White for the B team, managed to conjure up an unexpected attack in a Three Knights' Game and Rudy found dangerous counterplay. Analysis reveals that James missed a couple of chances, but when the attack ran out of steam, Black had a big lead in material. I played quietly against Sam Holman's Sicilian, transposing to an English-type position, in which I was the first to break in the centre. Sam's counter with the f-pawn created a weakness on e6, allowing me to establish a knight there, which proved a decisive advantage. Damien Clarke was unable to maintain the White pawn centre against Tony Geraghty in a Slav Defence, and then compounded his difficulties by dropping a piece, leaving Black with an easy win. The unplayed game has been registered as a win for the A-team, no doubt under League regulations, so the result is a 4-0 victory for them.

Across a Crowded Room

Aberystwyth's B team had a good evening on Tuesday 7 March, while the A team were losing narrowly to Cardigan in the cosy space of the small function room at the Brynamlwg Tavern. Julie van Kemenade, continuing her return to chess, played a typically enterprising piece sacrifice with Black against Iwan Griffiths to get a dangerous attack which he was unable to defend. James Corrigan dominated the centre against Owen Llywelyn's King's Indian, and the Black counterplay on the queenside was not enough compensation. Ian Finlay, playing another King's Indian, missed a chance to go a piece up, but Tegwyn Jones lost on time. On fourth board, Sam Holman did win a piece, and by the time Emyr Llywelyn had regained it, White's attack was unstoppable. A clean sweep for the B team, 4-0.

Standing Room Only

The capacity of the small function room at the Brynamlwg Tavern was tested to the full on Tuesday 7 March, when the A and B teams had matches at the same time. With the addition of another table, we were able to fit everyone in, and it is at any rate a cosier venue than the St David's Club was in its latter days. News of the B team match will follow in the next post. Cardigan were once again visiting, this time to play the A team. On top board Rudy van Kemenade had prepared carefully for his Leningrad Dutch against Howard Williams, but seemed to lose patience in the middle game, loosening his kingside in search of an attack that was not really there; instead it was White who broke into his opponent's castled position. Robbie Wright tried for pressure on the queenside in his London System against Iolo Jones, but ended up getting his rook pinned and losing the exchange, resigning rather prematurely when he still had some play. Adam Robinson also seemed to have pressure for a while against Tony Haigh's Trompowksy, but apparently missed a chance of an advantage just before the draw was agreed. I got a free gift from Awne Osinga when he dropped a piece on move 5 - not the first time that mistake has been made in the same postion in rated games, according to Rudy's database - after which I had no real problem clinching the win. As with last week's match, the top two boards secured victory for Cardigan, 2½-1½.
