Ruy Lopez, Chigorin Defense

The Chigorin Defense belongs to the Closed Ruy Lopez, a branch in which Black keeps the e5-pawn and both sides develop before resolving the central tension. Its defining move is ...Na5: Black's knight goes from c6 to a5 and normally makes White's bishop retreat from b3 to c2. By leaving c6, the knight frees Black's c7-pawn to advance.

Black usually follows with ...c5 to contest d4 and gain queenside space. The move ...Qc7 then supports the d6-pawn, indirectly reinforces the d6-e5 pawn chain, and supports the c5-pawn from the c-file, which may open after ...cxd4. The queen does not point directly at e5 because Black's own d6-pawn interrupts that diagonal. Black gets understandable counterplay, but the knight on a5 is far from the center. It must find a useful route, often through c6 or b7, before White uses the extra time to improve every piece.

...Na5 and the future ...c5 are connected parts of the plan: first c6 is cleared, then Black challenges the center.

The knight and c-pawn form one plan

The c-pawn cannot advance while the knight remains on c6. The Chigorin solves that problem with a move that also gains a tempo against the bishop.

1. ...Na5 and the future ...c5 are connected parts of the plan: first c6 is cleared, then Black challenges the center.

White commonly builds the center with d4, develops the b1-knight toward d2, and prepares maneuvers against Black's king. Black focuses on central and queenside pressure. The struggle is less immediate than a gambit, but the two sides often operate on different parts of the board, so a slow-looking maneuver can become important several moves later.
