Yeah, I taught my bro-in-law how to play a couple of years ago. First game I whooped him. I think we played a second game too, where I still got him good, though he had obviously gained experience. But third game I handicapped myself a rook, and I thought I was going to lose. He had me on the ropes, and only through a miraculous defense, I managed to capture his rook and slowly, very slowly, turned things around.
You are a much stronger player than he was, so I'm truthfully a bit scared.
