Annotated Game #307: The Colle that wasn't (quite)

After an early opening blunder led to a rapid loss in the penultimate round of the tournament, the following final-round game was a welcome point of stability. Both sides dance around entering the Colle System, with Black never committing to playing ...d5, while as White I pass up some more interesting alternatives on moves 12-13 that would have led either to a small positional plus, or a more imbalanced structure with attacking chances on the kingside. I correctly avoid a tempting-looking tactic later, but in a passive and slightly cramped way. Not my best game, but the careful road to a draw was still a positive outcome after the poor showing in the previous round, guaranteeing me a plus score for the tournament.

Annotated Game #306: The Stonewall Attack formula

The Stonewall Attack has an undeserved reputation as a "system" opening, although perhaps some people do play the first several moves always by rote. As with its Dutch Stonewall counterpart as Black - see Annotated Game #305 - it is important to pay attention to move-order issues and not expect the same sequence to work every time against different setups from your opponent. However, in certain circumstances there is indeed a "formula" that usually works for White, which I am able to achieve in this next tournament game. Here I demonstrate that I finally have learned the lesson of the e-pawn lever in this position-type - after which, I have at worst a pleasant game, while giving my opponent a chance to mishandle the defense, which he does on move 15.

What's wrong with this picture? From Lady Gaga's performance at the Coachella festival:

The first thing I noticed was that the bottom side's colors were reversed. Then I noticed the top side's were correct. Then I started counting squares...

That said, powerful use of the chess metaphor in dance and song.

Annotated Game #305: An endgame escape

This first-round tournament game had two big lessons. First, it highlighted a hole in my repertoire involving the move-order used to reach a Dutch Stonewall; I'll have to fix that for the future. Second, it demonstrated why at the Class level one should always keep yourself alive with practical chances in an endgame. Here I reached a situation where my opponent was up the exchange and could have sacrificed it back to lock in a win, but instead I exploited the opening he gave me to threaten mate and collect most of his pieces, forcing a resignation. A good illustration of why materialism can lead to bad outcomes in all phases of the game.
