I would love to see any computer play this move (of Tal). I have my doubts, however. Was there no better way of uncovering his bishop which points towards h7? Or was the K-file worth the sac? What happened (in the game), happened, but it's hard to believe it is the best move. Tal's position anyway looked very good, before that. S.Taylor
