In this variation Black tries to trade off several pieces in a bid for freedom; it results in a sound but barren position. That’s exactly why I like it! In this game White didn’t make any serious mistakes but allowed me a positional advantage on the Q-side, then made a slight weakening on the other side. The combined advantages allowed me to win the game. His correct strategy should have been, as is always the case, meeting a flank attack by an attack in the center.
