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.
Fencer: Nice site. But how about a "pro" version of 5-in-a-line which has a limitation to white`s second move. Check out IYT`s "Pro gomoku" to see what I mean. 15x15 board size would be perfect.
I know many top players who rather play the pro version than regular.
