March 2009 TNT Round 2

Boron - Lauritson 0-1
White never recovers his "gambited" pawn.

Rutter - Mundwiler 0-1
White drops an exchange; Black has everything under control culminating in giving back the exchange for a mating attack.

Khedkar-Atem 0-1
White could have grabbed a pawn with 24. Nxe6. White has everything under control until Black plays his only plan - pushing his passed a-pawn. White makes the final error with 44.Qe1. Instead 44. f3 and Black must still show how he is going to win.

Aaron Green - Kernetsky DRAW
I had a sense Black missed something - 27...Qc2 looks strong - perhaps winning a pawn, with threats of Rd3 or Rxf2 !

Wiebe-Lipic 0-1
Black is hopelessly lost (well almost) , until White forgets about a back rank mate.

Magnusson - Jim Green 0-1
White drops the exchange; Black has no problems converting.

Leo Wasserman - Campbell 0-1
35. Kf1 and it is likely a draw. The game's 35.Kh1 results in mate.

Milord - Trinidad DRAW
Black throws away winning chances with 42...e3. White salvages half a point after being on the brink of losing.

de Groot - Menard 1-0
White exploits the black sqaure weaknesses.

Evans - Swift 0-1
White retreats at a critical stage. He should play 23. Bxc5 Rxc5 24. Qe3
If 24...Nb7, then 25. Nd7 wins material. Instead, White loses a piece. Note that in the game 25. Bxc1 does not allow Black to win a piece.

Strehlow - Leah Green 1-0
I am thinking something is wrong with the game score - White didn't hang a rook on move 25 ?
Les tells me it wil be corrected.

Another great swindle that had no hope.
37... Re1+
0-1

after 38. Kh2 (only move)
38...Rh1#

The tactic of Bxc5 on move 17 is probably the only way to maintain a draw. I thought it would lose after Rc1 and b4... but maybe not.

I've had Fritz running Deep Analysis on the position for both sides after 17...Bxc5 and after 2 1/2 days it looks like Rac1 might be best, Fritz currently sits at a 1.45 advantage for White.

I think this means I should actually learn what B15 entails after the exchange on f6.

Or maybe find a new favourite after Nc3 (Gurgenidze Attack... maybe the Garbage Line... I like weird lines what can I say.)

17...Bxc5 looks a bit drastic at that time.

5...ef6 is playable, but it is very tough to play for a win.

5...gf6 is much more dynamic.

Peter Wells says 5...ef6 has a tragic flaw in that the doubled pawns lie on Black's majority side.

Gurgenidze is okay if you know the ideas.

Hope you like my Garbage line from round 5... hehe.

Fritz's final analysis of 17...Bxc5 is 1.29 advantage White after:

17...Bxc5
18 Rac1 Rxe3!
19 Rxc5 Qxc5!
20 Qxc5 Rxe2
21 Nxg6 hxg6
22 Qb5 Re7
23 a4 b6
24 Qc4 Rae8

White I believe is better, but that is how Black can "justify" Bxc5.

It does mean I'll have to look for some improvements earlier on.
