Championship Chess

PLAYED last night in the Battersea club championship.

Spanton (1921) - Ibrahim Abouchakra (1780)
Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Bg7 5.Nc3 Nc6 6.Nxc6!?
This is fourth in popularity in ChessBase's 2026 Mega database behind 6.Nde2, 6.Nb3 and especially 6.Be3.
6...bxc6 7.Bc4 d6 8.0-0 Nf6 9.e5!?
A pawn sacrifice that divides the engines. Dragon1 reckons it gives White the upper hand; Stockfish17.1 claims it is only enough for equality.
How should Black respond?

9...Ng4
IA said afterwards he rejected 9...dxe5 10.Qxd8+ Kxd8, which is the main line, because White can capture on f7, but he missed that after 11.Bxf7?? e6 the bishop is trapped.
10.e6?!
Almost certainly better is 10.exd6.
10...Ne5?
Black should play 10...f5.
11.exf7+ Nxf7 12.Bxf7+ Kxf7 13.Qf3+ Kg8?
Apparently a novelty. After 13...Bf6 14.Qxc6 Rb8 White is a pawn up and has the safer king, but Black has the bishop-pair and has the only pawns on the two central files, meaning White is only slightly better (Stockfish17.1) or at best has the upper hand (Dragon1). Indeed the engines reckon White should prefer 14.Ne4!? d5 15.Nxf6 exf6 16.Qc3.
14.Qxc6 Bf5 15.Nd5!?
The engines prefer 15.Re1.
15...Rc8 16.Qb7 Kf7 17.Bg5?!
The engines suggest 17.Qb3!?, 17.Re1 or 17.Qxa7.
How can Black cut White's advantage to a minimum?

17...Re8?
Better than the text is 17...Rb8, but best is the engines' 17...Qd7!, the point being that, after 18.Qxd7 Bxd7, the capture 19.Bxe7?? loses to 19...Bc6, while 19.Nxe7?! Rc5 20.h4 Bxb2 also favours Black.
18.Rfe1
The engines prefer 18.Qb3.
18...Bf8
Again 18...Qd7! works.
19.Qb3
Can you find a good reply for Black?

No ... or, to be on the safe side, if you have found a good reply, you have done better than the engines.
19...Bxc2?!
The engines' best is 19...Kg7, but 20.Qe3 leaves White well on top, eg 20...Kf7!? 21.Qf3 Kg8 22.c4!? h6 23.Bf6!? Qd7 24.Bxe7!? (Stockfish17.1), or 20...Qa5!? 21.Nxe7 Bxe7 22.Bxe7 Qb6 23.Qf4 Qxb2 24.Bxd6 (Dragon1).
20.Qf3+
Probably even stronger is 20.Qh3.
20...Kg7
How should White proceed?

21.Bxe7! Bxe7 22.Rxe7+ Rxe7 23.Qf6+ Kh6 24.Nxe7 Rb8
This, for a short time, is Stockfish17.1's top choice, but objectively best, or, rather, least worst, is probably 24...Ra8.
25.Qf4+ Kg7 26.Nc6 Qb6 27.Nxb8 Qxb8 28.Qd4+ 1-0
The bishop is also dropping.
