Optimisation of Position::see and Position::see_sign Stephane's patch removes the only usage of Position::see, where the returned value isn't immediately compared with a value. So I replaced this function by its optimised and more specific version see_ge. This function also supersedes the function Position::see_sign. bool Position::see_ge(Move m, Value v) const; This function tests if the SEE of a move is greater or equal than a given value. We use forward iteration on captures instread of backward one, therefore we don't need the swapList array. Also we stop as soon as we have enough information to obtain the result, avoiding unnecessary calls to the min_attacker function.
