Blunder file: Bishop sac
In an occasional series I look at blunders I've made - in the hope of remembering not to make them again. Here I think I've seen the classic bishop sac pattern Bxh2+ Kxh2 Ng4+ and that it's winning. It isn't. However, we both failed to spot that playing the king to the back row, usually fatal for the defender in this scenario, is actually safe, see variations, so I got away with it.
