Annotated Game #121: Quiet Symmetry

This penultimate round tournament game was a quiet Symmetrical English, which I thought my lower-rated opponent played well, although he was obviously unfamiliar with it.  It is one of those openings which Class players rarely use, perhaps because it lacks excitement or seemingly violates standard opening principles.  It also requires a good deal of patience to play properly and involves a lot of positional maneuvering.

Although the game appeared equal almost all the way through, in subsequent analysis, there were some improvements lurking for White, especially with 14. Bh3! - not a decisive move in tactical terms, but it would have resulted in a long-term positional advantage.  During the game I never considered moving the fianchettoed bishop off of g2, its "natural home".  Finding (and remembering) these types of moves is a key benefit of the game analysis process.

Black should have no trouble dealing with the remaining bishop alone.} Rc7 16. Rc2 Rac8 17. Rfc1 Nh5 18.
