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.
Is it possible to add a feature like 'analyze board' where if you click on a link it will bring up the board as it stands and then lets you move the pieces of both players to try out a few scenarios - no rule checking or anything required? Just a thought....
I've seen this feature on only one other site. It is indeed very useful. It's a pain getting a board out and going through variations, but this works well. You should be able to click on a little arrow or something to go back to the original position.
