Backward Moves

It’s been pointed out that the most difficult moves to foresee are backward retreats. The following game is a case in point. I totally overlooked White’s 22,Ne1 which left my N attacked twice…very embarrassing. Fortunately moves like that don't happen very often because I really don’t know of a good way of alerting yourself to the possibility that a retrograde retreat is in the air! I was lucky that my Q-side P's offered some counterplay and was further helped with my opponend ill-considered 39th move which exposed his K to a fork. You can never be too careful in any position, but we all know that.
