The Trompowsky,2...h6 System is one of the defining branches of the Trompowsky Attack — the line you reach when both players want the full fight rather than a quiet draw.

Plans & pawn structures
- 1The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
- 2Develop with a purpose: connect the pieces to a concrete plan (a break, a target square, an outpost) instead of making automatic moves.
- 3Watch the pawn breaks — both yours and your opponent's. In these structures the player who times the central break better usually wins the game.
