This last-round game is a fitting end to the tournament, as it reflects the low level of play I had consistently shown throughout. Coming out of a Colle-Zukertort opening setup that White chose, I had an equal position but could not figure out a worthwhile plan. This planlessness contributed to poor decisions which tied my pieces up and allowed White to take the initiative and never let it go. Analysis shows that I had more than one opportunity to level the game after inaccurate moves by White, but my thinking under pressure was muddled and I failed to see my own chances, as well as adequately falsify my moves (move 34 being an excellent example of this).
From a strategic point of view, the game is an interesting look at the hanging pawns structure and how it can be exploited. White in this case supported them well and eventually after exchanges obtained an advanced passed d-pawn, which tied my pieces down while he switched to a kingside attack. Hanging pawns are always double-edged, though, and I had plenty of chances to neutralize White's play.
I was glad to get this tournament over with, as you might imagine. We'll eventually see how my subsequent tournament went and to what extent I was able to recover my play. For a little while, though, I'll plan to do some more master-level commentary games which I've been saving up, for a change of pace (and better examples of play).
