Keene’s “Olympic” Simultaneous (29.09.2012.)

Weymouth hosted the sailing events at the recent Olympics and Dorset chessplayers marked the occasion by organising a simultaneous match against Grandmaster Ray Keene in the splendid surroundings of the library of Kingston Maurward College nearby. Twenty local players took on the GM, of whom 4 Wimborne players secured a draw, but Weymouth’s Allan Pleasants was the only winner, whose notes these are.

White: R. D. Keene. Black: A. Pleasants (188).

Pillsbury Defence  [A42]

1.d4 d6 2.e4 g6 3.c4 Bg7 4.Nc3 Nc6 5.d5 Nb8 6.Be3 Nf6 7.Be2 Nbd7 8.Nf3 e5 A bit commital;  9.h3 0–0 10.g4 Nc5 11.Nd2 a5 12.Qc2 c6 13.g5 Ne8 14.h4 f5 15.f3 Rf7 16.b3 Nc7 17.a3 cxd5 18.cxd5 Rb8 19.a4 N7a6 20.Nb5 fxe4 21.fxe4 Qe7 22.0–0–0 Understandably White wants to find somewhere safe for the king now that the f-file is open. However, it is not clear that it’s safe on the queenside either. 22…Bd7 23.Kb2 Rc8 24.Qb1 Nb4 25.Rc1 Rf4 Black gives up the exchange for excellent black square control. 26.Bxc5 If 26.Bxf4 exf4+ 27.Ka3 26…dxc5 27.d6 Qf8 28.Bc4+ Kh8 29.h5 Rf2 Hard to resist but not the best. e.g. 29…Bxb5 30.axb5 Qxd6 31.hxg6 Qxg6 30.hxg6 Rxd2+ 31.Kc3? White wins the exchange due to the threat of mate on h7. However, the king will become very exposed. 31…h6 32.Kxd2 Qf2+ 33.Be2 White had to beware of  33.Kc3 Bxb5 34.Bxb5 Qd4 mate. 33…Bxb5 34.axb5 Rd8 35.Rcd1 Qd4+ Black had originally intended 35…Rxd6+ 36.Kc3 Qe3+ 37.Kb2 Qxe2+ 36.Ke1 Qc3+ 37.Kf2 The king is now horribly exposed – Black scents a win. Better was 37.Rd2 Rxd6 38.Qb2 Qg3+ 39.Kd1. 37…Rf8+ 38.Kg2 Qe3 39.Rhf1 Qxe2+ 40.Kg1 Qg4+ 41.Kh2 Qh4+ 42.Kg2 Qxg5+ 43.Kh2 Qh5+ 44.Kg1 Qxg6+ 45.Kh1 Qh5+ 46.Kg1 Qg4+ 47.Kh1 Qh3+ 48.Kg1 Bf6 0–1 There is no defence to Rg8+ and a forced mate.

More details may be found on the Dorset website (dorsetchess.org.uk).

The solution to last week’s problem was 1.Qe5! leaving Black able only to capture either of the two adjacent knights, and depending on which one he takes, 2.Qb8 or 2.Qh8 are mate,

In this position from a game earlier this year, Taunton resident, Mickey Adams (White) looks reasonably secure, but Black has a surprising winning stroke. Can you spot it?

Black to play & win.
