Black, 479 (Q) vs. Jon Jones, 853

This was the second game of the 2021 Holiday Action. Once again, I built up a comfortable lead only to give it away.

The first of two the critical moves was 30...h5??. I saw that White's knight was trapped, but failed to realize that 31. Nh6+ would be check and, consequently, expose my own knight for recapture by White's bishop.

The second critical move was 34...Rbc7??. I was setting up for some joint rook action on the c file—possibly a rook trade; I forget—but entirely missed the fact that White's bishop's retreat also threatened the rook on c2.
