Ruy Lopez (Chigorin): Karpov vs Unzicker (Annotated Game)

Opening moves: 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6. Black chooses the Chigorin setup with ...Na5 and ...c5, but Karpov calmly opens the a-file and improves his pieces.

In this 1974 Olympiad game, Karpov opens the queenside with a4 and axb5, doubles rooks on the a-file, and only then starts a kingside attack. This lesson follows the 1.e4 PGN and explains how White plays on both sides of the board in the Chigorin.
