Position after:

(12) Canfell,G (2284) - Kordahi,N [C85] Perfect 10 Invitational Western Suburbs Leagues Club (3.2), 28.08.2001 [Kerry Stead] 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Bxc6!? An interesting opening choice by Greg, who snuffs out any chance Nick has of playing the Marshall Attack. 6...dxc6 7.Qe1 Shirov describes this as a 'rare but very tricky line' 7...Nd7 8.d4 [8.b3 was Kramnik's choice against Shirov in Dos Hermanos in 1996, which ended in a draw. ] 8...Bf6!? [8...f6 is the more usual method of securing the e5 square as a strongpoint, allowing the bishop to play a more active role. ] 9.dxe5 Nxe5 10.Nxe5 Bxe5 11.f4 Bd4+ 12.Kh1 Bg4!? Nick chooses the more active continuation. [12...0-0 was the solid alternative. ] 13.Qg3!?N Greg also decides to play an agressive move. [13.Nc3 Qe7 14.Be3 0-0-0 15.h3 Be6 16.Bxd4 Rxd4 17.f5 Bc4 �-� Forgach,A-Hoehne,V/Hessen 1990/GER (72); 13.c3 with the idea of getting developed as quickly as possible might have also been a consideration. ] 13...h5 14.h3 If we look at the advntages each side has, white's control of the centre is offset by black's bishop pair and slight lead in development. The main difficulty for black in this position is trying to find time to castle queenside. 14...Qd7 15.c3?! Bb6?! Nick felt this was inaccurate as he loses a tempo if he wishes to retain the bishop pair. [15...Be2! tactics allow black to make use of white's lack of development. 16.Re1 (16.cxd4 Bxf1 17.Nd2 Be2�) 16...h4 17.Qg5 Rh5!!; 15...Ba7 was his suggestion, although white would continue with similar development to the game. ] 16.Na3 Ba7? Looking to maintain the bishop pair at too much of a cost. [16...Be2 may still have been an option, with a possible continuation being 17.Re1 h4 18.Qxg7 0-0-0�] 17.Be3! Now that g1 is free for the king, hxg4 becomes a threat. 17...Qd3? [17...Bxe3 18.Qxe3+-; 17...h4 might be the best try, though after 18.Qf2 Bxe3 19.Qxe3 Bh5 20.Rfe1 white has the much easier game. ] 18.Rfe1 h4?? 19.Qxg4 Bxe3 20.Qf3 It is simply a clear piece. 20...Qd2 21.Re2 1-0

Position after:

(13) Lee,E - Stead,K (2119) [C41] Perfect 10 Invitational Western Suburbs Leagues Club (3.3), 28.08.2001 [Kerry Stead] 1.e4 e5 2.Nf3 d6 3.d4 Nd7 4.Bc4 Be7 5.0-0 h6 6.Nc3 c6 7.Be3 Ngf6 8.h3 Qc7 9.Nh4!?N [9.Nh2 g5 10.Bb3 Nf8 11.d5 Ng6 0-1 Plater,K-Branicki,I/Wroclaw 1955/EXT 98 (38)] 9...Nxe4?! A natural looking move, with the idea of freeing black's position, however tactics dictate that black must walk a tightrope if he is to survive. 10.Qh5! d5 Again the logical continuation. [10...Nxc3!? may have been a better way to survive, but allowing Qxf7+ is something one would rather avoid. 11.Qxf7+ Kd8 12.Ng6 Re8 13.bxc3 d5�] 11.Nxe4 dxc4 12.Nf5! I thought this was simply a blunder, but it turns out to be very strong tactically. 12...g6?! [12...Bf8 was the way to keep the position under control, though black still has development problems. It just seemed un-natural to follow up 9...Nxe4 with 12...Bf8. ] 13.Ng7+! Kd8? Now the tactics really start to appear. The poor position of the black king is the reason why these tactics work. [13...Kf8 is a stronger defense, but the king ends up with almost no protection. However it is better than the game continuation. ] 14.Qxg6! Nf6 Here I thought I was simply winning a piece, and was cruising to victory, however my judgement was a long way off the mark. 15.Qxf7! Nxe4 16.Rad1 Now the problems are starting to become more serious. Black's material advantage means nothing if the king is under threat, and the extra pieces have no time to help defend the monarch. 16...exd4 what else? 17.Bxd4 The discovery is decisive. 17...Nd6 18.Bf6!! The winning move and one I completely overlooked. Now black dies horribly due to the pins. 18...Qd7 19.Qxe7+ Qxe7 20.Rxd6+ Kc7 [20...Bd7 21.Ne6+ Ke8 (21...Kc8 22.Bxe7 Bxe6 23.Rxe6+-) 22.Nc7+ Kf7 23.Bxe7 Kxe7 24.Rd4+-] 21.Bxe7 a5 Hoping for a miracle, but the position is hopeless. 22.Rfd1 b5 23.Rd8 Rh7 24.Bf6 Bb7 I thought I might as well allow a pretty finish. 25.R1d7+ Kb6 26.Bd4+ c5 [26...Ka6 27.Rxa8+ Bxa8 28.Ra7#] 27.Bxc5+! The final blow. 27...Kxc5 [27...Kc6 28.Rc7+ Kxc7 29.Ne6+ Kc6 30.Rd6#] 28.Ne6+ [28.Ne6+ Kb4 (28...Kb6 29.Rxh7 Rxd8 30.Nxd8+-; 28...Kc6 29.Rd6#) 29.a3+ Ka4 30.Nc5#] 1-0
