Bristol’s Boniface Attack Tankard Award 2012 (18.08.2012.)

The Bristol League’s Steve Boniface Memorial Congress starts next Saturday and runs over the Bank Holiday weekend. In addition to the usual prizes will be the new Steve Boniface Attack Tankard. This is a prize awarded to the winner of any game played in the League this season that displays the spirit of successful all-out attack. I was sent 8 nameless entries to judge and after playing them through several times found this one repeatedly caught the eye.

White: Tom Thorpe (165). Black: Anthony Carver (120).

Sicilian Defence – Closed Var. [B23]

1.e4 c5 2.Nc3 Nc6 3.f4 d6 4.Nf3 e6 5.Bc4 Nh6?! 6.0–0 a6 7.d3 b5 8.Bb3 Na5 9.Qe2 to prevent c4 9…Nxb3 10.axb3 Bb7 11.f5 The attack commences. 11…g6 12.fxe6 fxe6 13.Bg5 Qd7 14.Nd5 White offers his knight for no immediate material gain, but it would be dangerous to accept. e.g. 14…exd5 15.exd5+ Be7 16.Rae1 (It would be tempting to claw back some material with 16.Bxh6 but that allows Black to get castled and the attack slows right down.) 16…Nf5 17.g4; 14…exd5 15.exd5+ Be7 16.Rae1. 14…Bxd5 15.exd5 Bg7 If Black tries to block up the centre with 15…e5 there would follow 16.Nxe5 dxe5 17.Qxe5+ Be7 18.Qxh8+. 16.dxe6 Qc7 17.Nh4 The Black king is trapped in the centre. 17…Rf8 18.Qe4 Ra7 19.Nxg6 another proffered gift, but Black wants to draw the sting of the attack by swapping off material. 19…Bd4+ 20.Kh1 Rxf1+ 21.Rxf1 Bg7 22.Rf7 More material is thrown into the fray. Black accepts, but has little choice from hereon. 22…Nxf7 23.exf7+ Kxf7 24.Qf5+ Kg8 25.Ne7+ Kh8 26.Qf7 Threatening mate on g8 26…Qb8 27.Bf6 Rxe7 If 27…Bxf6 28.Qxf6#  28.Bxg7# 1–0

White mates while his queen is en prise – a clinical finish.

The original plan was for the tankard to be filled with some of Steve’s beloved real ale, but a Plan B will be needed as the winner is only 15, recently coming 4th in the British U-16 Championship.

The solution to Dave Howard’s latest creation was 1.Qd7! and if Black tries 1…Kxc4 there follows 2.Qa4 mate as Black’s bishop is pinned and unable to intervene.

This problem by William Shinkman (1847-1933) is taken from one of the early books in Alain White’s “Christmas Series” that I recently acquired, entitled “The Theory of Pawn Promotion” (Stroud 1912). How does White promote his pawn and mate in 2 moves?

White to mate in 2.

Bristol League Congress 2012 – Open Winner (21.07.2012.)

David Buckley of the Bath Club retained his title when he won the Open Section of the recent Bristol League Congress. Here is his win from Round 3.

White: Stefan Lehmann (159). Black: David Buckley (208).

Alekhine’s Defence [B04]

1.e4 Nf6 Alekhine’s Defence, in which the idea is to tempt White’s pawns forward in order to make them objects of attack later on. 2.e5 Nd5 3.Nf3 The most common continuations here are 3.d4 or 3.c4. 3…d6 4.d4 g6 5.Nc3 Nxc3 6.bxc3 Bg7 7.exd6 cxd6 Black has succeeded in creating doubled pawns on his open c-file. 8.Bd3 0–0 9.0–0 Qc7 10.c4 e5 11.c3 Nc6 12.Be3 f5 13.c5 dxc5 13…e4 achieves nothing after 14.Bc4+ Kh8 15.Bf4 exf3 16.Bxd6 Qd8 17.Bxf8 Qxf8 18.Qxf3 leaving White with a small material advantage. 14.dxe5 Nxe5 15.Bf4 attempting to pin the knight, but fortunately Black has a check. 15…Nxf3+ 16.Qxf3 Qf7 17.Bd6 Rd8 18.Bxc5 Be6 19.Rac1 Bxa2 20.Rfe1 Bd5 21.Qg3 Re8 22.h3 b6 23.Ba3 Rac8 24.c4 Be4 25.Bf1 Kh8 26.Qb3 Rcd8 27.Qa4 All White’s five pieces are now on the edge of the board and not attacking anything specific. 27…Qb7 28.Rcd1 h6 29.Qb3 Kh7 30.Bb2 Qc7 31.Ba3 Bd4 With White’s bishops on the fringe of things, the black bishops take centre stage and cause major problems. 32.Qa4 Bc6 33.Qc2 Be4 34.Qa4 Bc3 35.Re3 Rxd1 36.Qxd1 Rd8 37.Qa4 Bd4 38.Re2 a5 Necessary to keep White’s queen quiet and free up his own to attack. 39.Rd2 Qf4 Attacking f6 and its defending piece. 40.Rxd4 Giving up the exchange. The alternative was 40.Bc1 but still loses a pawn to 40…Bxf2+ 41.Rxf2 Qxc1; 40.Qd1 loses even more material. 40…Qxf2+ 41.Rxf2 Bxf2+ 42.Kxf2 Rxd1. 40…Rxd4 41.Qe8 Threatening a perpetual check 41…Qc7 42.Be7 cutting off the defence. 42…Qe5 43.f4 Qg7 44.c5 bxc5 45.Bxc5 Rd1 46.Bf8 Qa7+ 47.Kh2 Rxf1 48.Bc5 Qc7! 48…Qxc5 allows avoidable counter-play. 49.Qf7+ Kh8 50.Qf6+ Kg8 51.Qxg6+ Kf8 52.Qxh6+ Ke7 53.Qg7+ etc. 49.Kg3 If 49.g3 Rh1#; The game is lost anyway, but  49.Qe5 avoids immediate mate. 49…Qxf4# 0–1

Last week’s game ended 1.Bg6 forcing Qf8 2.Bh7+ forcing Kh8 and allowing the knight to drop into g6 forking king and queen.

This week’s position resembles a real battlefield, in which Black is poised to mate or get a second queen at the very least, yet White can mate in 2.

White to play and mate in 2.
