Kh1 f5 19. exf5 Qb4 { White's pawns on the f-file just seem to be in the way, so Tal gets rid ofthem! } 20. f6 Bxf6 21. f5 {This not only offers up the pawn at f5, but also invites Black to capture the knight at c3. Tal realizes that the knight has no useful role in the attack on the enemy king.} 21... Rxc3 22. Rg3+ {The check drives the king into the corner, because the rook at c3 is pinned to the queen at b4.} 22... Kh8 {22...Bg7 23.f6 Rxg3 24.Qxb4 and White wins.} 23. Qh6 {The double on the rook at f8 and the bishop at f6 forced Black to resign. Why? It seems that Black can capture the rook at g3 and escape, but White is prepared for this.} 23... Rxg3 24. Bg6 {The threat is Qxh7 mate. There is no defense except to capture at g6. If Black captures with the f-pawn (the h-pawn is pinned by the queen), then White captures the rook at f8 with checkmate. So...} 24... Rxg6 25. fxg6 {Now White has the same threats. The next move is either Qxh7 mate or Qxf8 mate .} 1-0
