Thoughts on this game?
Good game.
You obviously know the French. It went ok for the first six moves or so. White’s a4 is a little unusual though. After 9. Bb5 I wondered why you did not play the obvious Bd7. Just develop another piece to an obvious square. Nf5 is premature when the knight on c6 is pinned. However, white let you off the hook a little by not just playing g4 and forcing the knight back.
Of course, you could play 12. … Nxe5 which is a motif I often use with positions arising from the French.
I thought you were winning after about 15 moves courtesy of white giving up the a pawn earlier. But maybe 15. … O-O was the time to castle?
Why play 17. … Rf8 when 17. … O-O achieves the same and gets your king safe? It is like you have an aversion to castling. If you castle and then play f6 (a classic move in the French) you have a solid game.
I was surprised white did not play 24. Qh6. But even so, you are still ahead despite the vulnerability of your king.
You then play a series of inaccurate moves. I think 25. … Kd7 was probably an error. I would play Ke7 so that I could meet Qg7 with Rf7.
- … Qd8 would probably be better than 27. … Rf7. After 27. … Rf7 there is a draw with 28. Nxf6+ Ke7 29. Ng8+ Ke8 30. Nf6+
And 32. … Qd6 just about holds white out whereas Ke7 starts to lose it.
You played ok. But I think if you had played 17. ... O-O rather than 17. ... Rf8 the result might have been different. Definitely not castling cost you.
