Thanks. I thought that maybe Nh5 is okay because it could stop whites kingside pawn storm but active play with the knight going on to c7 and b5 is better.
Again thanks a lot
Question involving theory on the najdorf.
Sort:
Nh5 is a bad move if white can attack it.
And indeed, on 13...Nh5 14.Ng3! makes the job!
Now if black takes on g3, white will have h file openned, Qh2 will follow...
So Black has to play Nf4, where the knight seems nice but not stable. White should protect g pawn with h4, and have this nice idea : Nd4!
U don't have this with Ne8, seems passive but u dont have any problem with your knight.
IM poucin is right. The reason 13...Nh5 is not a popular choice is 14.Ng3 Nf4 15.h4 a5 16.Kb1 a4 17.Nd4 (17.Nc1 is also interesting, and should give white some advantage) when praxis has shown that B lack is short of equality. The initial game on that line (17.Nd4) is AFAIK Topalov- DeFirmian, Rubinstein Memorial 1995.
In the game Shirov vs Van Wely 2007 (http://www.chessgames.com/perl/chessgame?gid=1444696), on move 13 black plays the knight to e8 (13...Ne8). Why is this? Why not play the knight to h5?
Thanks
