Polar Capital Jersey Op  2016.4.10  gm Hebden, Mark–Wojciechowski, Paul. Position after 17 moves.  

WHITE TO PLAY AND CRUSH!

diag3FEEAC67BA9ACADA

Bangkok CC Open 2016.4.13 Liang, Awonder–Abhishek,Das. Position after Black’s 27th move (27…Qe5?)

WHITE TO PLAY AND CRUSH!

diag3FEDC5B2EDAEEC69

Polar Capital Jersey Op  2016.4.11  gm Hebden, Mark–gm Williams, Simon.  Position after White’s 25th move (25.Qxb7) Ofcourse, White is routed, but it is always a pleasure for the spectators to see a grandmaster hung, drawn and quartered!

BLACK TO PLAY AND CRUSH!

—————————–

diag3FEEBEE902C525E8

Bangkok CC Open 2016.4.13 gm Halkias, Stelios–Teerapabpaisit, Wisuwat.  White stands a bit better, but Black has nothing to complain about.

13.Bf4!?

diag3FEEBEE9DC40A66A

Black should not play the routine 13…Nfd7 followed by …Ne5

13…Nh5?

diag3FEEBEEA7798DDA2

WHITE  TO PLAY AND CRUSH!

—————————–

diag3FEDE6908FBE06F0

Polar Capital Jersey Op  2016.4.12  gm Williams, Simon– wgm Houska, Jovanka. Position after 29 moves. Black is a bit better with his strong Knight on d5, and is threatening …Nxf4.  Even so, the calm 30.Bg3 would keep things under control…Williams, however, wanted to ‘play for the advantage’:

30.Bb5?

diag3FEDE6914A27E2CD

30…Qh5!

diag3FEDE691EBB6D48D

Probably Williams underestimated, if he did not overlook, this strong resource. Now if the Bishop retreats to g3 Black crashes thru with 31…Qf3+ and 32…Nxe3

31.BxR

diag3FEDE6928D45C64C

Now in the game Houska won convincingly enough with the pedestrian 31…Rxe8 32.Bg3 Qf3+ 33.Kg1 Nxe3 34.Nh3 Nc4 35.Qg2 Bxd4+36.Bf2+ Qxg2+ 37.Kxg2 e3+ etc.  HOWEVER, from the diagram above, Black has a much more decisive continuation.  Do you see it?

BLACK TO PLAY AND CRUSH!

diag3FEEE1415E7F0964

Bangkok CC Open 2016.4.11 Grafil, Franz R–gm Ganguly, Surya. Position before Black’s 24th move.  Despite having the better pawn structure, Black has a small edge because of the Bishop pair and his slightly more active Rooks (open files!)

24…Bd4+!?

diag3FEEE14218E8E541

An exploratory check to which White should respond 25.Kg2! and if 25…e5 26.Bh6 Rf7 27.Rcd1 with a defensible game.  INSTEAD, probably overconfident, White played the natural…

25.Be3?!

diag3FEEE142B4411C7A

Curiously, trying to exchange the dark square Bishop (and get rid of Black’s Bishop pair) only increases the power of the Biship pair!

25…Ra2!!

diag3FEEE1434F9953B2

An unexpected and brilliant tactical shot!

If now 26. Qxa2 Bxe3+ 27. Kg2 Bxc1 28. Rxc1 Rxf3!! is crushing; The best defence appears to be 26. Qd3!? Rxf3! (this motive is always in the position) 27. Rxf3 Qxe4 28. Qxe4 Bxe4 29. Bxd4 Bxf3 ,and though Black has an extra pawn, the opposite colour Bishops allow White some slim chances of saving the game after 30.Be5!? 

26.Nd2?!

diag3FEEE143EAF18AEA

Now Black can increase his advantage with the simple 26… e5! 27. Bxd4 exd4 28. Rf2 Re8 etc. INSTEAD, he gets carried away with the f3 tactic…

26… Rxf3?!

diag3FEEE1448649C223

Off hand, this looks decisive, but it allows White some slim drawing chances after 27. Rxf3! Qxf3 28. Qxf3 Bxf3 29. Bxd4 Rxd2 30.Be5! as in the previous note.  INSTEAD, White immediately blundered:

27.Qxf3?

diag3FEEE14521A1F95B

Probably a time pressure blunder….

27… Bxe3+ 28. Kg2 Qxf3+

diag3FEEE145BCFA3093

0-1.  White loses the house
