A strange and mysterious blunder was Fischer's 55 c5?? against Letelier at Mar del Plata 1959 (Pos. 311). It seems inevitable that he should have calculated the following line: 55 g6 b3 56 g7 b2 57 gS—W bl=#+ 58 <£f6#fl+59 &e7 #xc4 60 #xc4+ &xc4 61 &d6 &b5 62 &d5 &xa5 63 &c4, draw. Wishing to elicit from the position more than the position could possibly offer, Fischer hits upon 55 c5 <&xc5 56 <&e4!, and
White wins. What, however, he completely fails to notice, is that Black ignores the c-pawn and plays 55 ... b3, promoting the pawn at bl with check - exactly as in the above line, but with the unpleasant difference that here, a tempo down, it leads to White's loss. And this is how it happened: 55 ... b3 56 c6 b2 57 c7 bl=#+ 58 &e6 Wbl 59 &d7 <&d5 60 g6 #c6+ 61 <&d8 #d6+. and White had to resign.
Also very enigmatic are the next three cases, taken from earlier stages of the game, all of which have one thing in common: a blunder is committed in a position that must have been considered by Fischer previously, under slightly different circumstances.
