I really don’t want to turn this into a chess blog. So this is overdoing it a bit. Then again, I’ve been surprised at the number of people I encounter who enjoy these posts, so I won’t feel too bad. Anyway I enjoyed this problem. I guessed the move, which is an odd one, but which emerges from an analysis of the tactical constraints on black. But I wasn’t really sure that it was the right move, which is to say I didn’t really understand how powerful it was until I saw that it was the move, and then realised that, once made, black’s position falls apart.
