  The most dramatic more-pieces-than-pawns position was the final game of the 1910 World Championship Match, which was twelve pieces with five pawns in the critical position.  That was very good strategy on Lasker’s part, the position was too complicated for Schlecter to handle, he captured one of the remaining pawns, and that tactical error cost him the title.  My two computer programs can’t stop arguing about this week’s game.  No wonder, after move 24 there are eight pawns on the board with the fifteen remaining pieces;  after move 28, it’s fifteen and six.  It sort of makes me wonder what the other bughouse board looks like.
