Larsen–Spassky 1970 — An Attack That Drives the Pawn Home
Objective: Black to move. Find the winning attack and maintain at least a +2.0 advantage for 6 moves.
Position and task condition
White's h3-pawn has just attacked the knight on g4. Retreating the piece looks natural, but Black has a much stronger plan. Find the way to open lines around the king and carry the attack through the next six moves.
