In a hall adjacent to the playing room, Grandmaster Rossolimo was commenting on the games for a large audience. He had been completely mystified by this game; at this point, in fact, he told his audience that there was obviously nothing left for Fischer to do but give up. Suddenly, the messenger came with the next report, and announced that Byrne had resigned! Can you guess Fischer's deadly final stroke?} 21... Qd7 0-1
