Richter-Veresov Attack: what should White play?

In the Richter-Veresov Attack, White faces a critical decision regarding the g5 after Black challenges it with h6. The most statistically successful and frequently played continuation is Bh4, which maintains the tension and has been utilized in 57.9% of the 44,564 recorded games in this position. While the engine evaluation slightly favors Black at -0.15, White achieves a 52.2% scoring rate by retreating the bishop, leading to complex middlegame struggles.

Strategic choices for the g5-bishop

White primarily chooses between retreating the bishop or capturing the knight. The move Bh4 is the most popular choice, appearing in 26,000 games, as it keeps the pin on the f6 and prepares for the development of the kingside. Alternatively, Bxf6 is played in 27.1% of games, leading to the main line Bxf6 Qxf6 Nf3 Nd7 Qd3 Bb4. This exchange simplifies the structure but allows Black the pair of bishops, resulting in a nearly equal engine evaluation of -0.14.

Black's defensive setup

Following the retreat Bh4, Black typically continues with development in the sequence Bh4 Nbd7 Nf3 Be7 Bd3 c5. Black aims to challenge the center with the c5 break while ensuring the king's safety. If White opts for the less common Bf4, seen in 11.4% of games, Black often responds with Bf4 a6 Nf3 c5 Be2 b5, expanding on the queenside to seize space.

Risks and inaccuracies

The position requires precision, as aggressive attempts to trap the bishop or force complications can backfire. The move f4 is a significant error, played in only 0.1% of games with a severe engine evaluation of -3.53. This move fails to address the tactical requirements of the position, allowing Black to gain a decisive advantage after f4 hxg5 fxg5 Ne4 Nxe4 dxe4. Similarly, the check Bb5+ yields a low scoring rate of 33.9% for White, as Black comfortably blocks with Nbd7.
