Stop All the Clocks!

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.

Auld Enemy

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.

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).

Dyfed League Reopens

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.
