A thematic Knight reshuffling. The Ng1 will go to e2 and both Knights will defend the critical dark squares, especially d4.

"Black frees his passive Knight on d7" (Moskalenko), heading for e4 perhaps.]

An older move in this position, which clears the way for queenside development and and an attack on that wing.

The battle-lines are clearly drawn: Black will play on thequeenside and White needs to take action on the kingside, even if his King must castle there. One interesting game with the line went: [10...h5

Black's potentially connected passed pawns offer at least sufficient compensation for the piece. White must now continue his attack on the kingside, which should gain him a draw.

32.h4!
Threatening to hem in Black's King with h5. White's kingside attack appears to force a draw. Thomson's mistake seems to have been in trying for more. [32.Kg1
