Bobby Fischer vs Tigran Petrosian · 1971 · move 22.
Compare the historical knight exchange with a saved queenside pawn improvement. Which a-pawn advance does the search prefer?
In game seven of the 1971 Candidates final, Fischer chooses activity over a simple rule about keeping a strong knight. He exchanges the knight on c5 for a bishop, then brings both rooks to the seventh rank. The bishop that remains becomes useful through its cooperation with those rooks.
