6.c3 b6 7.Nbd2 Bb7 8.Ne5!?
Normal is 8.Bd3, but the text is also quite popular and has been played by my opponent's near-namesake Christhian Cruz (2579).
8...Nc6!?
This may be a novelty.
9.Ndf3 Bxe5
Stockfish16 and Komodo14.1 give 9...Ne7!?, eg 10.Bb5!? Nf5 11.Bc6 Bxc6 12.Nxc6 Qe8 13.Bxd6 Nxd6 14.Nce5 c5, claiming a slight edge for Black.
10.Nxe5 Nxe5 11.Bxe5 Nd7 12.Bg3 Qe7?
Careless.
13.Bxc7 e5?!
The engines strongly dislike this, presumably because Black ends up with an isolani.
14.Bxe5 Nxe5 15.dxe5 Qxe5 16.Qd4 Qg5 17.g3 Rac8 18.Bg2 Rc4 19.Qd3 Re8 20.0-0 Rd8 21.Rfd1 Rcc8 22.Rd2 h5 23.h4 Qe7 24.Rad1 g5!?
Desperately seeking counterplay before Black goes two pawns down.
25.Qf5 gxh4 26.Bxd5?!
Almost certainly much stronger is capturing one of the h pawns.
26...Bxd5 27.Rxd5 hxg3 28.Rxd8+?!
The engines much prefer 28.Qxh5.
28...Rxd8 29.Rxd8+ Qxd8 30.fxg3
The queen-and-pawn ending is completely drawn, according to the engines

30...Qd1+ 31.Kg2 Qd2+ 32.Qf2 Qd5+ 33.Kh2 Qxa2 34.Qd2 Qe6 35.Qd4 Qf5 36.Qd2 Kh7 37.Kg2 Qe4+ 38.Kf2 Qf5+ 39.Ke2 Kg6 40.Qd3?
This throws away the draw ... if Black plays precisely.
40...Qxd3+ 41.Kxd3 Kf5 42.Ke2 Ke4 43.c4
Black to play and win with an only-move

43...a5!
Other moves draw, eg 43...f6 44.b4! f5 (44...a5? loses to 45.c5 a4 46.cxb6 a3 47.b7 a2 48.b8=Q a1=Q 49.Qf4+ Kd5 50.Qd4+ etc) 45.b5 Ke5 46.Kd3 Ke6 47.Kd4 Kd6 gives a position in which neither side can make progress.
44.b3 f6 45.Kf2 Kd3 Kf3 Kc3 0-1
