3. Bb5 a6
4. Ba4 Nf6

Theory, Strategy, and Purpose of the Kholmov Variation

The Kholmov Variation aims to challenge White’s central control and create counterplay.

Of the various 9.h3 variations of the Ruy Lopez, the Kholmov Variation is largely considered the most accurate response with 9…Be6.

(9.h3 leads to the Chigorin, Breyer, Karpov, Smyslov, Zaltsev, Keres, and other popular Closed Ruy Lopez systems.)

The move 9…Be6 puts pressure on the b3 square, forcing White to make decisions that can lead to imbalances.

The main line runs 10.d4 Bxb3 11.axb3 (11.Qxb3 is another option) exd4 12.cxd4 d5 13.e5 Ne4 14.Nc3 f5 15.exf6 Bxf6 16.Nxe4 dxe4 17.Rxe4 Qd5 18.Rg4, where White’s extra pawn is seen as more valuable than Black’s active pieces.

Sub-Variations of the Kholmov Variation

There are several variations within the Kholmov Variation, leading to different types of positions.

The main line is as described above, but the move 11.Qxb3 instead of 11.axb3 is another significant option.

These variations offer different strategic ideas and tactical opportunities for both sides.

10. d4 or 10. Bxe6 is considered the best option for white.

10. Bxe6 is arguably the stronger move to double black’s e-file pawns.

Evaluation of the Kholmov Variation

The evaluation of the Kholmov Variation is +0.50 to +0.60, providing white a decent advantage.
