The November clinic features more games from the Tiger Chess Themed Training events on Lichess. This time the chosen them was the position arising after the moves 1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 in the French Defence.

I have issued frequent warnings about the caution required by Black in ever castling kingside when there is a White pawn on e5. Of course it's always good for people to discover this for themselves, and this is what happened in the following position (see diagram):

Black's last move was to castle kingside (15...0-0) which White then answered with 16.Nxh5!. Black actually resigned at this point (1-0) which might have been either great vision or a reluctance to continue with his king in such a desperate situation. At first it did not seem that clear to me but then Stockfish indicates that White is winning, for example after 16…gxh5 17.Ng5 Rfc8 18.Qxh5 Qxd4 19.a3 Ba5 20.Bf4 Bd8 21.Rhd1 Qc4 22.b3 Qxb3 23.Qh7+ Kf8 24.Rdb1 Qa4 25.Rxb7 etc..

At the moment these training events are featuring the Petrosian Variation of the King's Indian Defence and take place on Wednesdays (8pm UK time) and Sundays (6pm UK time). Participation is free and you can find them here.
