Lesson
White to move. Main line: 1. c4 Nf6 2. Nf3 g6 3. g3 Bg7 4. Bg2 O-O 5. d4 d6 6. Nc3 Nbd7 7. O-O e5 8. e4 c6 9. h3 Qb6 10. d5 cxd5 11. cxd5 Nc5 12. Ne1 Bd7 13. Nd3 Nxd3 14. Qxd3 Rfc8 15. Rb1 Nh5 16. Be3 Qb4 17. Qe2 Rc4 18. Rfc1 Rac8 19. Kh2 f5 20. exf5 Bxf5 21. Ra1 Nf4 22. gxf4 exf4 23. Bd2 Qxb2 24. Rab1 f3 25. Rxb2 fxe2 26. Rb3 Rd4 27. Be1 Be5+ 28. Kg1 Bf4 29. Nxe2 Rxc1 30. Nxd4 Rxe1+ 31. Bf1 Be4 32. Ne2 Be5 33. f4 Bf6 34. Rxb7 Bxd5 35. Rc7 Bxa2 36. Rxa7 Bc4 37. Ra8+ Kf7 38. Ra7+ Ke6 39. Ra3 d5 40. Kf2 Bh4+ 41. Kg2 Kd6 42. Ng3 Bxg3 43. Bxc4 dxc4 44. Kxg3 Kd5 45. Ra7 c3 46. Rc7 Kd4
Tal’s 21...Nf4 does not win by an immediate forced sequence. It changes the position: after 22.gxf4 exf4, Black gains open lines, a dangerous passed f-pawn and repeated threats against White’s king while Botvinnik has to solve concrete problems at every move.
The tactical point continues with 24...f3. White can take Tal’s queen with 25.Rxb2, but 25...fxe2 removes White’s queen in return and leaves Black’s pieces active. The combination is an exchange of imbalances, not a simple queen trap.
Tal converted the ending after the attack subsided. That second phase matters: the famous sacrifice created the winning chances, but accurate rook activity, the passed c-pawn and king centralisation were still required before Botvinnik resigned after 46...Kd4.
The sacrifice people remember — and the game around it
Game 6 of the 1960 match is usually reduced to one move: Tal’s 21...Nf4. That is understandable, because the knight is offered into a position where the consequences cannot be reduced to a neat forced mate. But treating the move as magic hides the more useful lesson: Tal had already arranged the board so that every open line would point toward White’s king.
Before the sacrifice, Black has doubled rooks on the c-file, placed the queen on b4 and advanced ...f5. White’s rook on a1 is awkward, the king has stepped to h2, and several white pieces are committed to defending the queenside. The knight does not create the attack from nothing; it removes the final restraint on an attack that already exists.
The position after 22.gxf4 exf4
Botvinnik accepts the knight with 22.gxf4 and Tal recaptures with 22...exf4. Black is a piece down, yet the new pawn on f4 cramps White, opens the e5 diagonal for the bishop and threatens to advance with tempo. White cannot simply consolidate because Black’s queen and both rooks are already active.
This is a useful way to evaluate practical sacrifices. List the durable gains: open files, a passed pawn, exposed king squares and active pieces. Then list the defender’s easy moves. If the material advantage cannot be organized because every move answers a threat, the attacker has compensation even when no immediate mate can be calculated.
The second combination: 24...f3
After 23.Bd2 Qxb2 24.Rab1, White attacks the black queen and appears ready to collect it. Tal answers with 24...f3, an in-between move that attacks White’s queen. The game continues 25.Rxb2 fxe2: both queens leave the board, but Black’s active pieces and pawn structure survive the exchange.
That sequence is why the game belongs in a tactical library as well as a historical one. Tal does not save the attacked queen. He changes the order of operations so that taking it no longer wins material cleanly. The zwischenzug works because the f-pawn created by the knight sacrifice arrived on exactly the square needed to attack e2.
An attacking game that still needed an endgame
The famous phase is over by move 31, but the game continues for another fifteen moves. Tal activates the king, creates a passed c-pawn and forces White’s rook into passive defence. Botvinnik resigns after 46...Kd4, when Black’s king supports the pawn and White has no useful counterplay.
That ending corrects a common misunderstanding about Tal. His strength was not merely a willingness to gamble material. The sacrifice created a difficult position; calculation carried it through the complications; technique converted what remained. A high-level replay should show all three stages instead of cutting away as soon as the queens disappear.
21...Nf4: A speculative knight sacrifice that maximises activity and forces White to calculate rather than consolidate.
24...f3: The tactical bridge between the sacrifice and the queen exchange: an in-between attack on White’s queen.
29...Rxc1: Simplification on Black’s terms. Once the attack has produced a favourable material balance, Tal is willing to exchange pieces.
A successful sacrifice usually begins before the sacrificed move, with active pieces and lines aimed at the target.
When your queen is attacked, check forcing in-between moves before retreating it automatically.
Compensation should be described concretely: activity, passed pawns, king exposure and tempi, not vague “attacking chances”.
Do not stop analysing when the spectacular phase ends; conversion is part of the combination.
