Aug-08-08  muradov: Instructive win by Wang. But Gelfand must have gone terribly wrong somewhere..

I think white is doing ok. He has impressive looking pawns on the king side that make up for his weakness on the other side of the board.

It seems though that Wang Yue gets the better game from here on out. I wonder if 30. Bf1 was as bad as it looks. I guess that Gelfand was afraid of 30...Nd3+ after 30. Kf2 that would appear to lose a pawn. However, after 30. Kf2 Nd3+ 31. Ke3 Nxb2 32. Rd7!

white looks pretty good here and may be winning.

Too bad for Gelfand though he did not play his bishop so well in this game. He further mishandles it with 46. Bd3!? allowing black's reply of 46... Bf3! and his poor bishop appears to just shuffle around aimlessly after this.

I would like to see some expert analysis of this game. Wang Yue plays an impressive game with black.

Aug-09-08  4tmac: I'm sure Wang Yue liked his 38th move. It appears he likes these simplified bishop endings and has the patience to exploit his opponents lack of plan. Gelfand finally was forced to hope he could save this

but Wang Yue was ready with Be4! and it was over quickly.

White has just played 51 b2-b3?

Black to play: 51 ... ?

<51...a3. An interesting alternative was 51...Bd1! and now 52.bxa4 (52.Bxd1 a3 wins) 52...Bxc2 53.axb5 cxb5 54.Kxb5 Kd6 and it is game over for White.>

So Wang Yue (Black) played 51 ... a4-a3, creating a dangerous outside passed a-pawn. But instead he could have won on the spot(!) with 51 ... ♗f3-d1!.

(VAR) Position after 51 ... ♗f3-d1!

The point is given in the principal variation (PV) of 52 ♗c2x♗d1 a4-a3.

(VAR) Position after 52 ♗c2x♗d1 a4-a3

Now the White b3-pawn <SELF-BLOCKS> the b3-square, preventing the White d1-bishop from occupying this square and <DEFENDING> the a2-square against the advance of the Black a3-passer, the a2-square being the last chance for the light-squared White d1-bishop to stop the Black a3-pawn from promoting as the a2-square is the final light square in the passed pawn's path.

The other variation after the instantly winning move 51 ... ♗f3-d1! consists of White capturing the dangerous Black a4-pawn but losing his White c2-bishop in the process, resulting in an obviously lost endgame.

(VAR) Position after 52 b3xa4 ♗d1x♗c2 53 a4xb5 c6xb5 54 ♔c5xb5 ♔c7-d6

So Wang Yue still won after playing 51 ... a4-a3 but 51 ... ♗f3-d1! would have forced instant resignation.
