Leonardis Variation

In the Leonardis Variation of the Russian Game, White plays 3.d3 instead of the much more common 3.♘xe5, opting for a solid and flexible approach. White maintains central stability while allowing natural piece development. It is a quiet and positional system that avoids heavy theoretical battles in the main lines of the Russian Game.

White’s Plan

• Develops harmoniously with ♗e2 (Tayler Opening; after Black’s d5 push, it resembles an inverted Philidor Hanham), then 0-0 and c3, preparing d4 to strike at the center later.
• Plays g3 and ♗g2, fianchettoing the bishop for a more strategic setup.

Black’s Plan

• After White develops the queen’s knight, Black challenges White’s slow setup with an early …d5, gaining space.
• Plays …h6 to prevent ♗g5 pinning the knight.
• Develops the dark-squared bishop to d6 (defending e5) or more aggressively to c5 if White plays slowly with 4.g3 or 4.c3. In that case, Black
• often consolidates the bishop by pushing a5.
