He analyzed a very long, complicated line where he could win 3 pawns for the bishop, and simply misjudged the resulting positions. GM Jon Speelman published an exhaustive analysis (~25 pages) of that endgame. It is incredibly complicated, and just *barely* losing for Fischer. So, yes, Fischer's move was a mistake, but not a silly one-move oversight like everyone thinks. --Peter
