Nf5 9. Bd2 Be7 10. g4 $1 {An interesting idea of Hungarian GM  Attila
Groszpeter, who first played it in 2002. White aims to advance his f-pawn to
f5 in order to disturb Black's light-colored bishop.} Nh4 ({After} 10... Nh6 $6
11. h3 {Black's knight on h6 is extremely restricted.}) 11. Nxh4 Bxh4 12. f4 {
Now White threatens to win a piece after 13.f5. Black must decide how to
counter this threat. There are three possibilities: 1. place bishop on e4; 2.
push f-pawn; 3) open a "window" for the bishop by advancing the h-pawn.
However none of these possibilities promise Black a sweet life.} h6 {After the
game both Zhigalko and Jobava critisized this move. Baadur said that during
the game he had a strong feeling that somebody had recommended him this move
before. He said he has not checked it himself and now finds it just terrible.
I would agree with him - if Black had a good alternative. But since Black has
no reasonable options, I consider 12...h6 playable. Black should probably
search for equality somewhere earlier.} ({The problem with} 12... Be4 {is that
