Analysis by Hairulov and Fritz 11

GM Bong Villamayor - Yeap Eng Chiam [D46]
KL Open 2008 (Round 1), 15.12.2008

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 e6 5.Bd3 Nbd7 6.0–0 Bd6 7.Nbd2 0–0 8.e4 dxe4 9.Nxe4 Nxe4 10.Bxe4 f5 11.Bc2 e5 12.Bg5 Be7 13.Bxe7 Qxe7 14.Nxe5 Nxe5 15.Re1 So far so theory. Fritz 11 opening book suggest 11...Qb4 as the main line. 15...Rd8?

This move cause black to lose a pawn. White is temporary a piece down but he will balance the material deficit after capturing the knight on e5 meanwhile black in turn should balance his pawn deficit by playing 15...Qb4 and after 16.Rxe5 Qxb2 . 16.Rxe5 Qxe5 17.dxe5 Rxd1+ 18.Rxd1 Eng Chiam is a pawn down in a rook + same colour bishop endings. It's hard to draw a pawn down position against a GM calibre opponent . 18...Be6 19.b3 Re8 20.f4 Kf7 21.Kf2 g6 22.h3 Ke7 23.Rd6 Rd8 24.c5 Rf8 25.a3 Rd8 26.b4 Rxd6 27.exd6+ Kf6 28.Bd3 a6 29.Ke3 h5 30.h4 Bd5 31.g3 Be6 32.Kd4

White have two possible plan :-

1. entering black king side by controlling the a2-g8 diagonal with his bishop and later his king penetrate tru e5; or

2. entering black queen side by controlling the a2-g8 diagonal with his bishop and later his king penetrate tru the uncontrolled dark square c3-b3-a4-a5-b6!

Black unfortunately can't defend both entry at the same time. Black only chance to enter white position is tru the light square ( d5) which is impossible because white light square bishops still "alive"!

32...Bd7 33.Bc4 After controlling the a2-g8 diagonal, white proceed with his plan to penetrate black position via c3-b3-a4-a5-b6! 33...Bc8 34.Kc3 Bd7 35.Kb3 Be8 36.Ka4 If black king's move to the queen side with g7-f8-e8-d8, white bishop will move to f7 and capture the g6 and h5. 1–0
