Czentovic immediately suggests a return game to restore his honour. But this time, having sensed that Dr B played quite fast and hardly took time to think, he tries to irritate his opponent by taking several minutes before making a move, thereby putting psychological pressure on Dr B, who gets more and more impatient as the game proceeds. His greatest power turns out to be his greatest weakness: he devolves into rehearsing imagined matches against himself repeatedly and manically. Czentovic's deliberation and placidness drive Dr B to distraction and ultimately to insanity, culminating in an incorrect statement about a check by his bishop, and then him conceding the game, after which Dr B awakens from his frenzy.
