I looked at so much analysis during this game that I was very tired by the time it finished.
My original plan was the winning 16.Qd3 with the idea of Nb5 (I didn’t see I was losing the c-pawn at first, but then realized it didn’t matter about the pawn if Nb5 comes after …Bxc5, and then realized that the position was very deep), but I didn’t appreciate it deeply enough, tactically, and my tactical skill level wasn’t there to see what I needed to see at the end of the lines I was looking at.
I looked at many, really all of the lines involving 16.Qd3. I also looked at 16.Nd4 Bxc5 Nb5 (one of the knights). Josh liked 16.Rb1 supporting this same …Bxc5, Nb5 idea (but it’s not as strong as 16.Qd3). I just now looked at two continuations with Fruite where White just gets tactically freaky at the end, and Black is up a pawn or two in those lines at some point, yet way down score-wise. I did look at c6 and b7 pawn pushes, but it has to happen in conjunction with the pieces, uber-tactically.
With this win for Josh, I basically made him an Expert level chess-player, rating-wise, and it was well-deserved on his part. I had 9 seconds at the end of the game, and he was under a minute!
