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.

1.d4 d6 2.e4 g6 3.Nc3 Bg7 4.Nf3 Nf6 5.Be2 Pirc Defence 0-0 6.0-0 e5 7.dxe5 dxe5 8.Qxd8 Rxd8 9.Bg5 Re8 10.Rad1 Be6 White decides to give up the two bishops, reckoning that his next move will force Black on to the defensive. 11.Bxf6 Bxf6 12.Nd5 Bxd5 So Black gives the asset back. 13.Rxd5 Nc6 14.Bb5 Rad8 14...Rab8 15.Bxc6 bxc6 16.Rxd8 Rxd8 17.Re1 Black's baddish bishop and queenside pawn structure are weaknesses. Bg7 18.Kf1 Kf8 19.Ke2 Ke7 20.Rd1 Rxd1 21.Kxd1 f6 White has a clear plan, to go after the pawns on the queenside. 22.Ke2 Kd7 23.Kd3 Bf8 24.Kc4 Now the Black bishop can't get to c5 and its only good diagonal, but White will still have trouble getting to the a-pawn. Ke6 25.Nd2 f5 26.f3 Be7 27.Nb3 Bg5 Taking another route. 28.a4 The advancing pawn can kick or even win the bishop when it reaches b6, and will be closer to queening if the a7 pawn falls. Be3 29.Nc5+ Kd6 30.Nb7+ Kd7 31.Kb4 h5 32.Ka5 The king advances. fxe4 33.fxe4 g5 33...Kc8 34.Ka6 Kb8 35.c4 c5 36.Nd8 is hopeless. 34.c4 g4 35.Ka6 Kc8 36.c5 h4 37.h3 Now the kingside pawns are safe. gxh3 38.gxh3 Kb8 39.b3 Ka8 40.Na5 Bxc5 41.Nxc6 Bd4 42.a5 42.Nxd4 exd4 43.e5 d3 44.e6 d2 wins for Black - I miscounted watching the game. 42...Bc3 43.Nxa7 Bxa5 44.Kxa5 Kxa7 45.Kb5 Kb7 46.Kc5 Ka6 47.Kc6 and Black resigns. A ruthless endgame by White. 1–0
