I just found a problem with using subscription though. I tried replace
second with millisecond, while the minimax was executing (about less than a
second) the program keep calling more AIMove.
subscriptions model =
if (gameIsNotFinished model && model.turn == AIToMove) then
Time.every millisecond AIMove
