Story Seach

hey guys, I am looking for an old story. I lost it when my hard drive crashed. It's called "Alien Games" and it's about a man who gets abducted and used as a chess piece. The man gets changed into a woman when, as a pawn, he makes it to the other side of the board. I don't remember who wrote it, and I don't know where else to look.

I should also mention that the author's name began with a J or an R.
