There’s nothing like the Sicilian Defense to give off that occasional realization that White is playing for checkmate.
The accelerated pairings are over, were voted down at the yearly meeting, so that the pairings for Round 1 were back to old-school.
The ending could have been more picturesque if Rebecca had played 24… Ke8, then either 25.Qg7 Ne7, 26.Nf6 mates or 25.Qxh7 Ne7, 26.Nf6+ Kf8, 27.Qh6 mates. The computer prefers 25.Qxh7 because it is a pawn, and 25…QxNd5 is actually forced.
I had 25 minutes remaining at the end of the game.
