Time Trouble

Club nights have been cancelled for the past two weeks as we had two successive home matches in our restricted quarters in the Students' Union. Even fitting four games into the space involved a certain amount of furniture moving. Not only that, but just before the match against Cardigan A on Tuesday 26 November, we discovered that three of our clocks had gone missing from the storeroom. It was not the first time this had happened, and on the last occasion they turned up again, having presumably been borrowed, but as I write we still haven't located them for the second time. Fortunately we were able to do some borrowing of our own, from the University team, and the match went ahead. On top board, Rudy van Kemenade played his favourite Leningrad Dutch, and tried to stir up a kingside attack, but Howard Williams bided his time and then struck back, taking advantage of the weakened kingside left by Rudy's advancing pawns. Adam Watkin-Jones reached what looked like a quiet position in an Italian Game against Iolo Jones, but he underestimated Black's queen and rook lined up on the f-file. A knight sacrifice broke his defences open, ending the game quickly. Julie van Kemenade played a good positional game against Tony Haigh with her d6 system against 1.d4 (Rat or Pribyl or whatever it's called). White was left with a bad bishop and a passive position trying to defend a backward pawn, and his exchange sacrifice solved nothing. I got nothing from my Vienna Game until Ben Brewer, trying to set up an ambitious kingside attack, castled on the queenside despite his open a-file. My attack was quicker, and although I should have finished it sooner than I did, my extra material was enough to win the ending. Yet another 2-2 draw for Aberystwyth, but it was a good result against a strong Cardigan team.

On Tuesday 3rd December we had our local derby against the University team. Adam Watkin-Jones on top board had a quiet game with his English Opening against Cameron Westwood. With both players castled on the queenside, neither looked likely to break through, and a draw was agreed. I was under slight but persistent pressure against Jan Piotrowski in an Alapin Sicilian, till he moved his rook away from the back rank to help his effort and allowed a sudden counter-attack against the vulnerable king. I missed the best move and only managed to win an exchange, but the ending was an easy one. Tom Gunn played the classic Greek gift sacrifice in his Colle System against Kieron Judge. Subsequent analysis shows it was not sound, but Black declined it, and despite winning the exchange, found himself in a mating net, ending an exciting game. Anson Howard, playing his first ever rated game, held his own for a long time against Toby Bates in what I think was a Queen's Indian by transposition, but weakened his kingside, which eventually allowed the White attack through. A win for the Town team, 2½-1½.

We have one more club night in the Union before Christmas, but may meet in the Arts Centre bar on 17 December if there is enough interest.

Slow Start

Aberystwyth's slow start to the season continued in our second match on Monday 14th October when we played Carmarthen at the Emlyn Cafe, Tanygroes. On top board, Rudy van Kemenade met Huw Morcom's 1.Nf3 in Dutch style by f5, a line that can be dangerous if you don't know what you're doing, but Rudy, as usual, was well prepared and reached a position where his knight was much stronger than White's bad bishop, eventually breaking through with his rooks. Julie van Kemenade had to give up the exchange against David Buttell's Sicilian; she had compensation, but her own vulnerable king succumbed before she could force home her attack. James Cook found himself with tripled pawns in a Caro-Kann against Robert Narayan-Taylor; despite this, the position was level for much of the game, till White was able to give up his passed h-pawn for a winning attack against the king. An h-pawn also came in useful for Tom Gunn, playing his first game for the club, against Mark Reynolds. His Colle System brought the kingside attack White tries for in this opening, and the runaway pawn provided support for the Queen to mate. A second 2-2 draw left Aber already with a bit of ground to make up on champions Cardigan.

Steynton B were the opponents at the Emlyn Cafe two weeks later, on 28 October. Rudy's Bird's Opening brought him a dominant centre, which Mark Paffard tried to break up with a bishop sacrifice. After the resulting complications, White's attack was eventually stopped but by now he had an overwhelming material advantage. Adam Watkin-Jones steered for an ending against Scott Hammett's Stonewall, but might have been better advised to keep some of the minor pieces on - he had no advantage in the king and pawn ending, and might even have lost at one point trying to force a win. My Exchange Variation against John Miller's French brought me slight but persistent pressure in the centre, and I was able to win a pawn and the resulting ending as Black played too passively. Tom Gunn, after his winning start in the first match, was brought down to earth in his second. He neglected to deal with a pinned knight when defending Jonathan Jones's Jobava London System, allowing the kingside to be ripped open. At last a win for Aber, 2½-1½.

The Dark Night Returns

***UPDATE: We will be meeting in Room 2 of Aberystwyth University Students' Union this Tuesday, 8th October, at 7.15. ***

With the onset of dark nights and chilly weather, the new chess season is under way, and the Aberystwyth team duly arrived at the Emlyn Cafe, Tanygroes on Monday 30th September for the first match of the season, away to Cardigan B. Aber were the higher graded team on paper, but the match was much tougher than the gradings suggested. On top board Rudy van Kemenade struggled to get an advantage with Bird's Opening against a well-prepared Tony Haigh, but eventually entered a double rook ending a pawn up. Tony had active pieces, though, and Rudy, who was not playing as rapidly as usual, went wrong under the pressure, dropping his passed pawn to leave a losing position. New member Roger Bennett, playing Board 2, was hemmed in against Ben Brewer's Reti, unable to get his light-squared bishop into play; trying to prevent a White incursion on to the vulnerable second rank, he walked into a knight fork that soon decided the game. My Vienna Game against Joshua Brewer took an unfamiliar path and reached a middlegame with opposite castled positions. Black never completed his development, and I broke through against the queenside-castled king with a rook sacrifice. I have an uncomfortable feeling that this is my first win in a rated game in 2019. James Cook had to weather an uncharacteristically aggressive attack from Awne Osinga in a Queen's Pawn Game. Awne's Greek Gift sacrifice was probably sound, but not at all easy to play, and James struck back to force mate. A 2-2 draw was not the result Aber wanted but there's a long season ahead.

The Club will be meeting in Aberystwyth University Students' Union at 7.15 every Tuesday from next week. Thanks to our friends in the Aberystwyth University Chess Club for arranging this. Anyone may attend, and there is no charge, but if you haven't been before, please leave a message on the blog before attending for the first time. We will probably be in Meeting Room 2 or 3 at the Union, but I don't know for certain yet, and will update when I know. It shouldn't be difficult to find us anyway.
