At least in chess there are irreversible moves (pawn moves and captures) which guarantee that any position achieved before will not happen again. So one could write an UCI engine that would send the last position after an irreversible move followed by the sequence of moves since then. In GO, this is probably a more serious problem. Yes, there is no such thing as an irreversible move in go. I think we are stuck with sending the whole list of moves every time we want to describe the current state of the game. Álvaro.
