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.
What if, instead of each member of a team play against each member of the other, the teams could play one game (or match of games), where the members of a team decide on what the next move would be? Working together like a team and not just a group of individuals working for each other the whole time.
When it was the turn of one of the teams, each team member would vote on the next move and the move with most votes would be the move for the team. Or the team members discuss the move between them and the team captain makes the move.
Another option could be for a particular player to play against a whole team for a bigger challenge. Just to see how good he/she really is.
I got the idea from www.letsplaychess.com from their "somebody vs rest of the world" matches and think could be something nice to implement here at BK.
