Masrin Erowan – Mohd Fadli Zakaria (2213)

Royal Selangor Open 2004 (Round 2)

White to move & win.

Delaune,Richard K (2400) – Alexopoulos,Georgios (2260) [D11]

World op 22nd Philadelphia (6), 03.07.1994 [Alexopoulos]

1.c4 c6 2.Nf3 d5 3.d4 Nf6 4.Qc2 g6 5.Bf4 Na6 6.e3 Bf5 7.Qb3 Nb4!!

A really amazing move that has given Alexopoulos several spectacular victories, including wins over International Master Shipman and International Master Delaune!! 8.Qxb4 e5 9.Qxb7 exf4!!

Alexopoulos prefers this to the theoritical recommendation of 9…Rb8 [9…Rb8!? is the “mainline”] 10.Ne5 Bd7!! [10…Nd7 11.Nxc6; 10…Be6 11.Qxc6+; 10…Be7 11.Nxc6] 11.Nxd7 Nxd7 12.Qxc6 fxe3!!Β 

White has a material advantage, but Black has counterplay on the b-file and the “weakened” dark squares.Β  13.fxe3 Rb8!! Targeting the dark squares. Not 13…Bb4+ when after 14.Nc3 White is ready to castle. [13…Bb4+?! 14.Nc3 0–0 15.0–0–0Β±] 14.Qxd5 [14.b3 Bb4+ 15.Nd2 Qe7!! (15…Qh4+!?; 15…Qa5!?) 16.0–0–0 Qxe3 17.Qxd5 0–0Β΅ for example, if 18.Qxd7 Qc3+ 19.Kb1 Ba3–+] 14…Rxb2 15.Be2 Bb4+ 16.Kd1 [16.Kf2 is better] 16…0–0

Black is fully developed and White’s King is caught in the open 17.Rf1 Qe7 18.Qf3 Ba5!!

Threatening 19…Qb4 as well as Rfb8 19.a3 Rb3!! Not giving White any respite and continuing to “soften” the dark squares! 20.Qd5 Qxe3!!

Threatening 21…RxNb1+ 21.Qxa5 Qxd4+ 22.Kc2 [22.Nd2 Qxa1+ 23.Kc2 Qb2+ 24.Kd1 Rxa3–+; 22.Qd2 Qxa1 23.Qxd7 a) 23.Bd3 Nc5 24.Bc2 (24.Rf3 Nxd3–+) 24…Rxb1+ 25.Bxb1 Qxb1+–+; b) 23.Ke1 Rxb1+–+; c) 23.Kc2 Qa2+–+; 23…Rxb1+ 24.Kd2 Rxf1 25.Bxf1 Qxf1–+; 22.Ke1 Qxa1–+] 22…Qb2+

[22…Qb2+ 23.Kd1 Qxa1 24.Ke1 a) 24.Kc2 Qa2+ 25.Kd1 (25.Kc1 Rxb1#) 25…Rxb1#; b) 24.Kd2 Qa2+ 25.Ke1 Rxb1+ 26.Kf2 Re8 27.Re1 (27.Rxb1 Rxe2+ with mate to follow) 27…Rb2–+; 24…Rxb1+ 25.Kf2 Rxf1+ 26.Bxf1 Qf6+ 27.Ke1 (27.Kg1 Qb6+ 28.Qxb6 axb6–+; 27.Ke2 Re8+–+; 27.Kg3 Qxf1–+) 27…Re8+ 28.Be2 Qa1+ 29.Kf2 (29.Kd2 Qb2+–+) 29…Qb2 30.Qe1 Ne5–+] 0–1
