Just as if the opposing pieces were not even on the board and as if he had failed to register all the important possible motifs.} O-O-O $3 {A splendid move from Caissa's box of tricks. You need Olympian calm to be able to play such a tranquil move in this situation. Castling kills off all of White's illusions. It is not only the one move which wins for Black, but it is also the single move which does not lose,} ({e.g.} 12... dxe6 13. Bxb2 Qd7 14. Qh5+ g6 15. Qf3 O-O-O 16. Nf7 Be2 17. Qxe2 Qxf7 18.

The tide was turned by brilliant castling} 0-1
