3 d/move "Piano Piano" tournament, Chess.com, 2020
Play becomes tactical, and illustrates my need to work on that part of my game.
19.e5 dxe5 20.dxe5 Nd5
This looks like an ordinary move, but it is a mistake, starting with the fact that it overlooks the pin on White's e-pawn. After the game Stockfish 11 had this to suggest: 20...Kh8 21.Rf2 (If Black's Queen comes to d4, it won't be with check) 21...Bb7 22.Re1 Re7 23.Qxh6 (Time to take the pawn ) Qf8 (Offering to exchange and relieve the attack) 24.Qh4 Bd5 (To aid in the blockade?) 25.c4 Bb7 26.g4 Nd7 27.Qg3 h6 28.f6 (At last) Re6 29.Rf5 Qc5+ 30.Kh2 Rg8 31.Qf4 Rg6 32.Kg3 Qf8 33.Re3 Qf7 34.b4 Kh7 35.Nf3 Bxf3 36.Rxf3

Here the computer sees White as less than a pawn and a half ahead. I can not imagine ever reaching this position, and I share it only because it illustrates how a complications can become even more complicated.
Back to the game.
21.f6+ Kg6
Brave, but 21...Kg8 was not much better, as the attack would continue.
22.Qd3+ Kf7 23.Qxh7+ Ke6
Solid. Readers with an eye for the attack will not doubt find 24.Qf5+ Kf7 25.e6+ Rxe6 26.Qh7+ Kf8 27.Qh8+ and White will win the Queen. I had quickly abandoned the line during the game, because of 25...Bxe6, but that was silly, as then 26.Qh7+ Kf8 27.Qg7#.
24...c5 25.Qf5+ Kf7 26.Qh7+
Missing e5-e6+ again, but it does not matter.
26...Ke6
27.c4
Upon reflection, a bit strange. The idea was to help build a checkmating net - 24.Rae1 was the same. Of couse, 27.Qf5+ was the way to end things.
27...Nb4 28.f7
Trying to mix the threat of pawn promotion with the checkmate threats. Guess which move was better?
28...Rf8
Instead, 28...Qd4+ would have allowed him to last a little bit longer.
29.Qf5+
At last.
29...Ke7 30.Qf6+ Kd7 31.Qd6 checkmate
