Central London League

FACED a junior (born 2009) on board one (of five) for Battersea against HMC in division one last night.

Stanley Badacsonyi (2329) - Spanton (1924)
Jobava-PriƩ
1.d4 e6 2.Nc3 d5 3.Bf4 Bd6 4.Bxd6!?
More popular is 4.e3.
4...cxd6
And here blacks have generally preferred to recapture with the queen.
5.e3 Nc6 6.Nf3 Nf6 7.Bd3 0-0 8.0-0
Now both sides have castled, how would you assess the position?

White has developed one more piece and has the better bishop. But Black has a pawn-majority on the central two files and is about to solve the problem of the bad bishop in a way that menaces White's setup. Stockfish16 gives Black a slight edge; Komodo14.1 reckons Black has the upper hand.
8...e5 9.dxe5!?
This may be a novelty. Known moves are 9.Be2 and 9.Re1?? The engines suggest 9.Nd2.
9...dxe5 10.e4 d4 11.Nd5!?
Perhaps White should have settled for 11.Ne2.
How should Black proceed?

11...Nxe4!
The engines agree this is best, but also good is 11...Nxd5 12.exd5 Qxd5 as 13.Bxh7+?? fails to 13...Kxh7 14.Ng5+ Kg8 15.Qh5 Bf5.
12.Bxe4 f5 13.Nc3 fxe4 14.Nxe4 Bg4 15.Qd3 Bxf3 16.gxf3 Rf4 17.Qb3+ Kh8 18.Kh1
The engines reckon White should plunge in with 18.Qxb7!?, although after 18...Rc8 they agree Black's development and safer king more than compensate for being a pawn down.
18...Ne7 19.Rg1 Qd5?!
Black probably should not be encouraging an exchange of queens. The engines give 19...Qd7, claiming Black has the upper hand.
20.Nd2?
White should exchange queens.
20...Qxb3?
Black shouldn't! After 20...Qc6 the engines give Black at least the upper hand, eg 21.Rg5 Ng6 22.Rag1 Rc8 with what they reckon is a positionally won game.
21.axb3 Ng6 22.Rg4 a6 23.Rxf4 Nxf4 24.Re1?!
This may look natural but the engines much prefer 24.c4 or 24.Ne4.
What should Black play?

24...Re8?!
What could be more natural than developing the rook and protecting the attacked pawn? But the move is passive, and what can be thought of as a golden rule in endings is to avoid passive rook moves. That is why the engines give 24...Rc8!, eg 25.Rxe5 h6, after which Black penetrates down the c file, and White's pawn-structure is further damaged.
25.Re4?!
Probably better is immediately activating the knight with 25.Nc4.
25...Kg8
The engines suggest 25...b5.
26.Nc4 d3
Black has a slight edge after 26...Ng6, according to the engines.
27.cxd3 Nxd3 28.Re3 e4!? 29.Kg1 b5 30.Nd6 Re6
The engines reckon Black is a tad better after 30...Rd8.
31.Nxe4 Nxb2 32.Rc3
Threatens 33.Rc8+ Kf7 34.Ng5+ etc.
32...h6 33.Kf1 b4?
The game is completely equal after 33...a5 or 33...Re8, according to the engines.
34.Rc8+ Kh7 35.Ke2
The black knight cannot be saved.
The game finished:
35...Re5 36.Rc2 Rh5 37.Rxb2 Rxh2 38.Ra2 Rh5 39.Rxa6 Rb5 40.f4 g5 41.fxg5 hxg5 42.Rc6 Re5 43.Ke3 1-0
HMC won the match 4-1.
