Top right corner of the board, yep that little gear thingy next to the rook. Run your cursor up to it and Flip Board is revealed. And no I have no idea why they hide it....
Flipping the board


I have asked for them to look at adding the continuation button but have not heard anything yet. Is there a way to get the continuation button without having to play a move then click the back button on explorer?

i still have the "flip board" feature. It's of paramount importance when studying your opponent past games (specialy the openings).
Am I right in thinking that at one time you could flip the board to look at the game from your opponents point of view, if so why was this feature discontinued, and is this possible to bring back
