Championship Chess

PLAYED last night in the Battersea club championship.

Michael Krautzberger (1505) - Spanton (1938)
Sicilian Alapin
1.e4 c5 2.c3 e6!? 3.d4 d5 4.exd5!?
There are 6,208 games with this continuation in ChessBase's 2026 Mega database, keeping the game in independent Alapin lines, whereas there are 3,928 games with 4.e5, transposing into the Advance Variation of the French.
4...exd5 5.Nf3 Nc6 6.Be3 cxd4!? 7.Nxd4 Bd6
Black has felt obliged to take spend a tempo (6...cxd4!?) in accepting an isolated queen's pawn, but in compensation the white dark-square bishop is not particularly actively placed and the white queen's knight will take two tempi to reach the active f3 square, now that c3 is occupied

8.Bd3 Nf6 9.0-0 0-0 10.Nd2
How should Black proceed?

10...Ng4!
This was probably also good at move nine, which is why Stockfish171.1 and Dragon1 recommended h3 on the last two moves.
11.Nxc6?
Allowing a simple zwischenzug, although 11.N2f3 Nxe3 also favours Black.
11...Bxh2+ 12.Kh1 bxc6 13.g3?
This only makes matters worse.
13...Nxe3 14.Qh5 g6 15.Qxh2 Nxf1 16.Rxf1
Black is 'only' up the exchange and a pawn, but Black's advantage is close to the equivalent of a whole rook, according to the engines

CLL: Central London League
LL: London League
BCC: Battersea club championship
CDL: Croydon & District League
I also have a win-by-default in the Central London League
*A win against a 1505 counts as a 1905 performance, so I have excluded this game from calculating my season's performance as it would lower my average despite me winning.
