Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
actually, what is interesting is that ANY game where you select a piece to move that has only 1 legal move, the "legal destination square" is selected for you.
If you make a move and the opponent has only 1
"legal move" in reply, it would make sense for that move to be made immediately.
But, that is non-trivial to implement, and could add to the overhead of the site.
