Tal–Timman 1972 — A Winning Middlegame Combination
Objective: White to move. Task goal: find the winning combination and maintain a +2.0 advantage for 5 moves.
Position and task condition
White has active pieces around Black's king, but the black knight has just landed on e5 and appears well placed. Tal found a concrete combination that completely changes the balance of the position. Calculate several moves ahead and look for a way to exploit the activity of White's knights and Black's exposed pieces.
