6. ....c5. This goes back to a basic premise of chess, when one person attacks on the flank (g4) then the other person should secure the center or take control of the center if possible. Galkin is playing for the center, and hopes that with a strong center he can without the kingside attack.

9. Nxh5 Nc6 Shirov vs Yermolinsky, 1999 This is still pretty established theory that has been played at the high level. White plays for the material by taking the H pawn, but again like we noted earlier black pretty much gambits the pawn for control of the center.

13. Qf3. White protects the h1 rook while putting pressure on the weak f7 square. Black has very few pieces defending on the queen side right now, so this is a very important positional move. Topalov vs Gelfand, 2002

13. Kf8? Even though this has been played before at the highest level, chessgames.com database does not have a win for black in this variation.

I feel that this moves black's king into the fire! Since the white Queen is already putting a lot of pressure on the f7 square, I don't think this is a good idea to pin the king behind the f7 pawn. I think a better move would be Bf8. This protects the G pawn that the black king tries to protect, and keeps the black king out of hte line of fire.

17. RaD1, if black takes the knight with the pawn black gets checkmate the next move. White just has a strangehold on the position right now. Black's pieces are jumbled, and there is no real way out.

20. Rd7. The rook penetrates the 7th rank and white has a stranglehold on the position. Even though black can play it out a little longer, like an anaconda white will just squeeze the life out of the position.
