Spanton (1829) - Hugo Romero Nieto (1561)
Morra Gambit Declined
1.e4 c5 2.d4 cxd4 3.c3 Nf6 4.e5 Nd5 5.Nf3 Nc6 6.cxd4 e6
The analysis engines Stockfish14.1 and Komodo12.1.1 reckon Black is equal after 6...d6 7.Bc4 Nb6 8.Bb5 dxe5 9.Nxe5 Bd7.
7.Nc3 d6 8.Bd2 dxe5 9.dxe5 a6
9...Nxc3 10.Bxc3 Qxd1+ Rxd1 gives White at best a tiny edge, according to the engines.
10.a3 Be7 11.Rc1 0-0 12.Bd3

12...h6?
The engines like 12...Ndb4!? I thought it was probably good for White after 13.Bxh7+ Kxh7 14.axb4, but I missed that Black has 14...Qd3, when the engines evaluate the position as equal. The text weakens Black along the b1-h7 diagonal.
13.Qe2 f6
This, or 13...f5, is necessary, according to the engines, but after ...
14.exf6 Nxf6 15.0-0
... White is clearly better.
15...Bd6!?
The engines prefer 15...Nd4 or 15...e5, but much prefer White.
16.Rfd1 Bb8 17.Ne4 Ng4?!
Hoping for counterplay against the white kingside, but a probably better way to avoid exchanging knights is 17...Nd5.
18.Bc3 Qc7

19.Nd6!?
This is the engines' second choice, but they agree 19.h3 is even stronger, the point being 19...Nge5 loses to 20.Bxe5 as the c6 knight is pinned, while 19...Nf6 20.Nxf6+ gxf6 leaves the black king horrendously weak.
19...Qe7!?
Black is also lost after 19...Qxd6 20.Bh7+ Kxh7 21.Rxd6 Bxd6 22.Qd3+ etc, and after the engines' 19...Nxf2 20.Kxf2 Qb6+ 21.Kf1 Bxd6 22.Qe4, eg 22...Rf5 23.Bc4.
20.Nxc8 Rxc8 21.Re1 Re8 22.h3 Nf6 23.Bg6 Bf4?!
Giving up the exchange instead of a pawn.
24.Bxe8 Rxe8
Or 24...Bxc1 25.Bxc6 etc.
25.Rcd1 Nd5 26.Be5 Nxe5 27.Nxe5 Qg5 28.Nf3 Qh5 29.Qe4
29.g4? Qxh3 30.Rxd5 Qxg4+ 31.Kf1 Qh3+ is a draw.
29...Kh8
Best, according to the engines, is 29...Kf7, but 30.Rxd5 Qxd5 31.Qxf4+ should win easily.
30.Rxd5 1-0
