Catching Up 1

Now the Christmas holidays here, I sat down to fix the game replayer problem that has prevented me from updating the blog for the last few weeks. I had thought up an elaborate work-around, and was just in the process of trying it out when I blundered on the real solution. The replayable games were not displaying properly because there was not enough room for them on the blog page. When I clicked on a blog entry, the games displayed properly because there was now only one entry on the screen. So I've set the blog to display three entries at a time instead of seven, and that seems to have solved it. Now to catch up with all the game reports I've missed. I'm going to do this a day at a time, like the twelve days of Christmas, only not so many.To save time,and because the matches were some time ago, I'll just give the match result in tabular form rather than a verbal report.

New Venue from 13th December

Aberystwyth Chess Club is moving to a new venue. From 13th December, we will be meeting in Brynamlwg Bar and Restaurant at Aberystwyth University. As before, meetings will begin at 7.15 on Tuesday evenings. Meanwhile, apologies for slow progress on restoring the game replayer. I have come up with a solution to the problem, and normal service will be resumed on the blog over the Christmas holidays.

Game Replayer Problem

I'm sorry that the new Chessbase game replayer is not currently working on this site. I am trying to find out what the problem is - it worked a couple of weeks ago. We do not have the option of going back to the old system, as Dropbox no longer support it. I'd be grateful for any advice - please leave a message in the comments section.

Not Quite an Upset

The Dyfed League is off to a slow start this year, and, with several players about to take part in the European Chess Club Cup in Novi Sad, Serbia, this state of affairs looks likely to continue for a while. However, the A team has had their first match,at the Emlyn Cafe, Tanygroes on Wednesday 26th October, against Carmarthen. In the absence of Carmarthen's formidable top board, Gerry Heap, Rudy van Kemenade was a strong favourite against Paul Orton, but things didn't work out that way. White had a strong attack against a Sicilian, but Black's efforts to find counterplay led to a very sharp position in which it was easy to go wrong. Rudy missed a win of the Black queen as he miscalculated a variation and walked into a mate for a rare defeat. Adam Watkin-Jones was also much higher-rated than his opponent, Richard Thomas, but again the result was unexpected: in a quiet middlegame with opposite-coloured bishops Black could see nothing more promising than a draw. Normal service was resumed on the bottom two boards. Robbie Wright got an advantage from Robert Narayan-Taylor's dubious opening, but it faded after a while. With the position still complex, though, Black eventually went wrong and lost material. Adam Robinson's Modern Defence brought him some kingside pressure against Steve Tanner, who lost a piece and was soon facing a mating attack. Not quite an upset, then and a strong Aber team will be relieved to have come through 2½-1½

First Match

Aberystwyth's first match of the season took place at the St David's Club on Tuesday 4th October when the B team took on Gwyddbwyll.com. On top board, Robbie Wright was in trouble against Iwan Griffiths's French Defence but Black's unnecessary exchange sacrifice let him back into the game, and when Iwan gave up the two bishops as well the ending was simply winning for White. James Corrigan, returning to the team after a year's absence, won the exchange against Owen Llywelyn's Ruy Lopez, but went in for some complications that ended in him giving the material back. White seemed to be better when the draw was agreed. In another Ruy, Sam Holman had worked up a crushing kingside attack before Tegwyn Jones lost on time, the first victim of the new increment-based time controls. Conor McEwan reached a level ending against Emyr Lywelyn, but White then dropped a couple of pawns and allowed him to take control. The match finished 3½-½ to Aber B.

Congratulations to Rudy

Congratulations to Rudy van Kemenade and the Welsh team on their performance in the European Seniors Team Championship in Halkidiki, Greece, in April. The team finished an excellent 4th, only narrowly missing out on the bronze medal, while Rudy scored 4/7, and came close to winning against a Grandmaster.

In Rudy's absence, the A team played a match against Gwyddbwyll.com at the St David's Club on Tuesday 26th May. Julie van Kemenade obtained a crushing kingside position against Iwan Griffiths with her King's Indian, while his queenside advance came to nothing, leaving him with a hopeless defensive task. Adam Robinson had a slight advantage in a Caro-Kann with a long way to go when Owen Llywelyn got a knight trapped and resigned. On fourth board, Tony Geraghty won a piece early on against Emyr Llywelyn, and clinched the game with a deadly pin. My game on Board 3 came to an early and unfortunate end when Tegwyn Jones was taken ill with a stomach bug. Happlily, he felt well enough to drive himself home after a while, and the game was abandoned. League Controller Iolo Jones, in Greece with the Welsh Seniors team, ruled that the game should be awarded to Aberystwyth, but neither player's grading should be affected by the result. Aberystwyth therefore won the match 4-0.

Iwan Griffiths - Julie van Kemenade 0-1

Adam Robinson - Owen Llywelyn 1-0

Tegwyn Jones - Matthew Francis 0-1 (default)

Tony Geraghty - Emyr Llywelyn 1-0

Too Complicated

The recent spate of matches between Aberystwyth and Haverfordwest continued on Wednesday 13th April when the two A teams met at the Emlyn Cafe, Tanygroes. It is not often Rudy van Kemenade complains that a game is too complicated, but his game against Colin Denham seems to have bemused even him. Mind you, he was playing Black in a King's Indian (by transposition) in a line where he had once lost to the great Bronstein, who knew a thing or two about complications. If it was a bit much for Rudy it was even more so for Colin, who was the first to crack under the pressure of time and tactics. Julie van Kemenade's game against John Miller, by contrast, was a blocked French Defence, where it seemed neither side would be able to break through. Julie missed the point of Black's careful manoeuvring which threatened to win a pawn and dominate the position. She was still unaware of the danger when she offered a draw, and her opponent, somehow doubting his own success, accepted. I was once again playing Scott Hammett, whom I had beaten in the previous match. This time I got nothing out of the opening or the middlegame (and should have lost a pawn), but managed to take control in the knight and pawn ending, marching my king up the board and creating zugzwang. A temporary sacrifice of my knight in the corner opened up the centre for my king and passed pawn, allowing a transposition to a won pawn ending. Jamie Friel sacrificed his bishop on f7 in a King's Gambit against Gwyn Evans but neglected to secure the centre and lost quickly. A 2½-1½ win meant Aber A overtook their own B team to restore their traditional precedence.

Colin Denham - Rudy van Kemenade 0-1

Julie van Kemenade - John Miller ½-½

Scott Hammett - Matthew Francis 0-1

Jamie Friel - Gwyn Evans 0-1

Alphabetical Disorder

With the season drawing to a close, Aberystwyth B have turned the alphabet on its head by overtaking the A team in the Dyfed League. Following the latter's disastrous match against Haverfordwest B, it didn't look unlikely that the B team would do better against the same opponents, whom they outgraded on all boards. And so it proved when the teams met at the Emlyn Cafe, Tanygroes, on Wednesday 6th April. The new Welsh Ladies' Champion Julie van Kemenade was under some pressure against Martin Jones on top board, with her king still in the centre, when he miscalculated his attack and lost material, and her passed pawn clinched the win. I had the advantage from an early stage against Scott Hammett's unorthodox defence to 1.e4, but found it difficult to get over the line, even missing a mate in two. However, my attack was good enough for a material gain that carried me through the endgame. Tony Geraghty, the only Aber player who had featured in the A team's defeat, got a French-player's dream position out of the opening, but, despite being a piece and several pawns up, he took rather longer to finish the game off than he would have liked. On Board 4, Sam Holman has been on good form recently and had no problems against Sandra Whitby, who showed her inexperience by moving her queen several times in the opening. A 4-0 whitewash for Aberystwyth B made a point to the A team not long before the second Aber derby match.

Martin Jones - Julie van Kemenade 0-1

Matthew Francis - Scott Hammett 1-0

Gwyn Evans - Tony Geraghty 0-1

Sam Holman - Sandra Whitby 1-0

Blacker Wednesday

Having already called a recent post Black Wednesday, I am at a loss what to call my description of Aberystwyth A's match against Haverfordwest B at the Emlyn Cafe, Tanygroes on Wednesday 16th March. It sometimes happens in chess that a player will lose to an opponent graded 3-400 points lower: it adds an element of unpredictability that helps make the game interesting. But it doesn't usually happen three times in the same evening. On top board, Rudy van Kemenade played a very sharp game against Martin Jones, and both players got a bit lost in the complications. Mating combinations were missed, before White eventualy emerged with an extra rook. Adam Robinson was the one Aber player who came out on top, keeping his cool as Scott Hammett plunged into more complications that never looked soundly based with his Latvian Gambit. Tony Geraghty tried to sacrifice his way out of trouble against Robbie Coles, and was soon a rook down without compensation. On fourth board, Jamie Friel dropped a piece against Ray Greenwood, but had a chance to draw the king-and-pawn ending, which would have made Aber's defeat a little less devastating. 3-1 to Haverfordwest B.

Martin Jones - Rudy van Kemenade 1-0

Adam Robinson - Scott Hammett 1-0

Robbie Coles - Tony Geraghty 1-0

Jamie Friel - Ray Greenwood 0-1
