League Chess

PLAYED on board one (of five) for Battersea against Hammersmith 2 in Central London League division two last night.

Tom Townsend (1996) - Spanton (1986)
Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.Nc3 Bc6 4.d4 cxd4 5.Nxd4 Bg7 6.Be3 Nf6 7.Nxc6!?
This is fourth-most popular in ChessBase's 2025 Mega database, behind 7.f3, 7.Be2 and especially 7.Bc4.
7...bxc6 8.e5 Ng8
Black can try a gambit with 8...Nd5!? 9.Nxd5 cxd5 10.Qxd5 Rb8, when Stockfish17 and Dragon1 reckon 11.0-0-0!? (more common is 11.Bc4) gives White the upper hand.
9.Bd4
How should Black proceed?

9...c5!?
The main line in Mega25 runs 9...Qa5 10.Bc4!? Bxe5 11.0-0 Nf6!? 12.Re1 d6!? 13.Bxe5 Bxe5 14.Qe2, with an equal position, according to the engines, but there are plenty of promising alternatives for both sides along the way.
10.Bxc5 Qc7
Probably not 10...Bxe5?! as White has 11.Qd5.
11.Bd4 Bxe5 12.Nb5!?
The engines suggest 12.f4!? or 12.Qd2.
What should Black play?

13...Qxb4+ 14.c3 Qa5 15.Bxe5 f6 16.Bc7 1-0
Hammersmith 2 won the match 4.5-0.5.

*My season's performance is slightly better than this as my win against a 1578 is a 1978 performance, lowering my average despite me winning.

Pen Of Participation

A RULE at the world senior team championships banned players from using their own pens.
But at the end of the final round we were allowed to keep the official pens we were using, which was somewhat more useful than the certificates-of-participation we also received
