Ruth Coxhill Memorial, 2008
I got my revenge for last year!

1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.b6 Qxb6 6.Nc3 d6 7.a4 g6 8.a5 Qb4 {To provoke White's next, in the hope that the R would be displaced.} 9.Ra4 Qb7 10.e4 Bg7 11.Be2 {11.h3 is more in the spirit of the variation. White's Ps box Black's pieces in, as long as none are exchanged. But if Black can exchange some minor pieces, then the remaining pieces are not so cramped, and White's structure looks loose. Compare the game below} 11...0-0 12.Nf3 Bg4 13.Nd2 Bxe2 14.Qxe2 Nbd7 15.0-0 Ne8 16.Nc4 Nc7 17.Bg5 Rfe8 18.Ra3 Nb5 {See, with fewer minor pieces on the board, Black can work around White's cramping Ps and exploit the holes.} 19.Nxb5 axb5 20.Rb3 [20.Nb6 b4] 20...Qa6 21.Na3 b4 22.Qxa6 Rxa6 23.Nc4 Ne5 24.Nxe5 Bxe5 25.Be3 [25.Ra1 Rea8! 26.Bxe7? f6!-+ trapping the B in my web] 25...Rxa5 26.f4 Bg7 27.Rc1 Rea8 28.Kf2 Ra1 29.Rc2 f5 {a typical move in Benko endgames, undermining the Pd5} 30.exf5 [30.e5 Rd1] 30...gxf5 31.Bc1 Rb1 32.Ke2 Ra2 33.Kd3 Raa1! 34.Kd2 Bh6 {To provoke White's next, denying the R access to the K-side. But even if White had played Rf3, this would have been tied down and Black could run the K over to the Q-side as per the game continuation} 35.g3 Bg7 36.h3 h5 37.Re3 Kf7 38.Rb3 Bf6 39.Re3 Ke8 40.Rd3 Kd7 41.Re3 [41.Rb3 Kc7 42.Rxb4? Rxc1!] 41...Kc7 {As usual with Benko endgames, Black's P base on e7 is very safe, while White's Ps are weak.} 42.Rb3 Kb6 43.Re3 Kb5 with the deadly threat of ... c4 then ... b3 44.b3 Bc3+ 45.Rexc3 [45.Kd1 Bb2] 45...bxc3+ 46.Rxc3 Rxc1 {simplest} 47.Rxc1 Rxc1 48.Kxc1 c4 49.Kb2 cxb3 50.Kxb3 Kc5 0-1

Well done Jono.

Is that really when he resigned ?

Well done Jono.

Thanx Garrett. Yes, he did resign there.

Froehlich had an upset loss to Jonas Muller last night too.

Well done to Jonas

He seems to be playing well lately.

Yes, Jonas had a good win over Nik Stawski, bottling up the Q-side pieces then overpowering him on the K-side:
1.e4 c5 2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 5.Bc4 e6 6.f5 Nge7 7.fxe6 dxe6 8.O-O O-O 9.Kh1 Nd4 10.Ne2 Nec6 11.c3 Nxf3 12.gxf3 Ne5 13.Bb3 Nd3 14.Bc2 e5 15.Ng1 f5 16.Qe2 fxe4 17.fxe4 Nf4 18.Qc4 Be6 19.Qxc5 Qg5 20.Qf2 Bh3 21.Nxh3 Nxh3 22.Qg2 Rxf1 23.Qxf1 Qh4 24.d4 Nf2 25.Kg1 Rf8 26.Qe2 Nh3 27.Kh1 Nf2 28.Kg1 exd4 29.cxd4 Nh3 30.Kh1 Rf2 31.Qc4 Kh8 32.Be3 Qg4! 0-1

I had a lucky escape from Peter Froehlich, who really needed to win because he had already dropped two points while I had dropped only 0.5:
1.d4 Nf6 2.Nf3 d5 3.c4 e6 4.Nc3 Be7 5.Bg5 O-O 6.e3 h6 7.Bxf6 Bxf6 8.Qd2 c6 9.Bd3 Nd7 10.O-O dxc4 11.Bxc4 e5 12.h3 exd4 13.exd4 Nb6 14.Bb3 Bf5 15.Rfe1 Qd6 16.Qe3 Nd5 17.Nxd5 cxd5 18.Rac1 Rac8 19.Rxc8 Rxc8 20.Ne5 Bc2? [an oversight, but Black was already under pressure] 21.Bxc2 [21. Nxf7 Kxf7 22. Bxc2 and the opposite coloured bishops are not the drawing potential he feared, but a powerful attacking weapon] 21... Rxc2 22.Nxf7 Qc7 23.Qe8 Kh7 24.Ne5 Rc1 [White should never have allowed the R exchange. Now Black is holding on] 25.Nf3 Qc2 26.Qe6 Rxe1 27.Nxe1 Qxb2 28.Qxd5 Bxd4 29.Qe4 Kg8 30.Nd3 Qa1 31.Kh2 Bf6 32.Qe6 Kh7 33.Qf5 Kg8 34.Qd5 Kh7 35.f4 Bd4 36.Qe4 Kg8 37.Qxb7 Bg1 38.Kg3 Qxa2 39.Qc8 Kh7 40.Qf5 Kg8 41.Qc8 Kh7 42.Qf5 Kg8 43.Qc8 1/2-1/2
