1. g1f3  1... g8f6  2. g2g3  2... c7c5  3. f1g2  3... b8c6  4. d2d4 This move is not a good attempt to gain an advantage. 4... c5d4  5. f3d4  5... h7h5 What a curious move! Out of nowhere Black decides to advance the h-pawn instead of developing the pieces. Of course this is an exotic move and not the most popular in this position. In fact, it's only the seventh most played, quite a feat considering that Black doesn't have many moves available. The idea is to get the pawn to h4, but should White worry about that? 6. h2h3 To me, advancing the h-pawn, whether to h3 or h4, is losing the psychological battle, if such a thing exists. I think White should be fearless and choose 6.c4 or 6.Nc3. 6... e7e5  7. d4b5 This is a new move in this position and it is no exaggeration to say that it's already a losing mistake. 7... d7d5  8. g2d5 This move is the only justification for white's previous play, but black's initiative is devastating now. 8... d8a5  9. b1c3  9... f6d5  10. d1d5  10... c8e6 Black's moves are natural and good.
