Black can play h5, g5, f5, and take it from there, any time during the game. >What is white going to do about it ? Play g4 and h4. Notice where _black's_ king is. Notice where white's king is. White can play g4/h4 to increase his space over there if black doesn't get something started reasonably quickly. The problem here is that if black doesn't push a pawn, he shuffles a piece. That gives white a free move. Enough free moves and black dies on _both_ sides of the board. > >I think this game was a low swindle by Kasparov.

But playing your "opponent" rather than the "board" is a common enough idea...
