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
