Annotated Game #290: Winning is good enough

This second-round tournament game saw me employ the Stonewall as Black against my opponent's Colle-Zukertort setup. I don't the the matchup of structures is favorable to White, although some tactical ideas did pop up in the middlegame related to the idea of freeing the Bb2 and creating a Q+B battery on the long diagonal. My kingside pressure was too great, however, and once I found the winning idea on move 18, it was essentially over.

It is worth highlighting that there was a better winning idea on move 19, but I struggled to calculate that particular line. Once I realized that the other line also won, however, I did not waste further mental energy in trying to figure out which was the best winning move - it did not matter. This I think is a valuable practical choice in tournament games, often encountered more in the endgame; who cares if it takes an extra several moves to win, if there is a simple way to do so? Winning in the end is good enough.
