Gordon Shumway: I almost never click on "choose another piece" but hit the back button if I didn't like a move. But I do always use the "choose another piece" button if I want to start the move over. I agree that something like "restart turn" is more accurate, but I figure that was entered when he was writing the site with a chess program.
