Checks to see if the last move played by the opponent is vulnerable.
If so, returns the killing move; otherwise, returns INVALID_POINT.
If we've killed this opponent stone, give it to ourselves. This often helps to find more vulnerable opponent moves.
If opponent's last move can be made unconditionally dead, this is preferable since we can treat it as such in the future, thereby finding more opponent vulnerable cells.
