Oh, how wonderful it is to find humor in missed opportunities. One thing that chess surely teaches everyone is that no one is infallible. There are optical illusions, and there are quirks of the brain. My opponent may have two pieces for a rook, but I had two more pawns on the queenside. I had just played my rook to d2, intending to double up on the f2 square with my other rook, when my opponent relied with Bd1??? I was so fixated on my plan that I simply decided that the e2 square is no longer mine. So, like any red-blooded chessplayer, I grabbed a pawn, Rb2. Sometimes, I need a mate in one to land and peck me on the head.
