White didn’t make any serious errors but lost a tempo (too valuable to waste when you’ve sac’d material) when he needlessly retreated his B from c4 to b3. Another small wasted move was a3 driving my N back even though it’s not posted in a great position on a6.
We arrived at the following position with White to play:
White played 13.Qg4+ and after 13...Kf7 14.Qh5+ Kg8 15.Qxe515...Bxf2+ 16.Kh1 Bxe1 17.Bxd5+ I had the surprising 17...Qxd5! picking up a piece because the Q is immune owing to the mate threat on f1. White soon lost.
Even though Black stands better in the diagram White had a couple of interesting moves:
The sacrifice 13.Rxe5+ is unsound and Black can wriggle out of difficulties with 13...Kxe5 14.d4+ Bxd4 15.Qe4+ Kf6 16.Nxd5+ cxd5 17.Qxd4+ Kg6 with a pretty safe position but there’s still chance for a lot to go wrong for Black.
Another possibility was 13.Qh3+ Kf7 14.Qxh7 Be6 arriving at the following position:
In this position the Firebird engine says that after 15.d3 Bd4 16.Be3 Rh8 17.Qe4 Nc5 18.Qf3+ Qf6 arriving at the following rather messy position:
19.Bxd5 Bxd5 20.Qg3 Bxe3 21.Qxe3 Nd7 22.Ne4 Qh6 23.Qg3 Kg8 24.h3 Rf8 25.Qg4 Bxe4 26.Rxe4
Even though White's attack wasn't successful this time, I think I need to be a little better booked up just in case I run into this line again!
