i do think blacks move 15 was good however i must grab the pawn and see if i can hold the draw.

16.Nxa4

you must play Nh5 here as in game and then my probs start.like Vas i did not think much of Jonny's move 17.Kh2 and feel sure i can improve on this.Rybka wants to play 17.Nc3 however i am not convinced yet that this is whites best move.remember i am fighting for a draw in this game.

it is very difficult for white to defend this,i just cannot understand moves like 11.Ra2 just shows that if the program is not strong enough it does not matter how much hardwae you back it up with.

anyone apart from me think i can get a draw,maybe i am being optimistic.
Parent - - By Uly (Gold) [mx] Date 2010-12-03 00:59
I think you can get a draw, I rushed into this position because evaluations kept raising, but now they've stabilized, just a bit better than with 22...Nc6.

It has been very exciting, it's the first time that I'm been actively pondering (thinking when it's your turn to move) :smile:, perhaps I can do it effectively in the WBCCC.
Parent - By NATIONAL12 (Gold) [gb] Date 2010-12-03 01:13
i just thought it was better to preface e5 with Nc6.
Parent - By TheHug (Bronze) [us] Date 2010-12-03 09:08
This is probably a little easier to draw than the Crawley Game 2, but Vytron maybe able to surprise you :smile:
Parent - - By Dadi Jonsson (Silver) [is] Date 2010-12-03 10:12
The probability of a draw has been increasing and after 22...e5 anything but a draw would be a surprise.
Parent - - By TheHug (Bronze) [us] Date 2010-12-03 10:21
I guess you follow these higher level games more than I thought :smile:.
Parent - - By Dadi Jonsson (Silver) [is] Date 2010-12-03 10:24
I had already started analyzing this variation before the current game started.
Parent - - By TheHug (Bronze) [us] Date 2010-12-03 10:32
Do you have improvements for white before move 15? For surely there is a better move than 12.Ra2? That looks very bad.
Parent - By Dadi Jonsson (Silver) [is] Date 2010-12-03 10:37
Of course 12.Ra2 is a terrible move, but I started my analysis after White's 15th move.
Parent - By TheHug (Bronze) [us] Date 2010-12-03 10:37
11.Be3 doesn't look that great either. That is possible were one can start to make improvements for white. Statistically Black is good here, but I have b3 and Rb1, not sure what is the best move
Parent - By Uly (Gold) [mx] Date 2010-12-03 17:25
Hey, maybe after this game is over we have another Nightmare challenge where I am defending the white side from after 22...Nc6 against you :smile:
Parent - By Dadi Jonsson (Silver) [is] Date 2010-12-03 13:22
After having a closer look, I would still prefer Black here.
