Through the past week, I have been playing less blitz. More importantly, I have been analyzing my games after playing them. It is humbling to observe elementary mistakes.
After botching the opening (the Black side of an English), I was let back into the game through my opponent's errors. I reached a clearly won position.
Black to move
Over the course of the next three moves, I repeatedly failed to make the winning move. Then, my position became worse and I lost.
Missing the same correct move three moves in a row suggests there was an oversight that might be addressed through training. Perhaps I can work some tactics exercises that incorporate this pattern.
