I thought I'd give it a try on my HTC One-X, but I cannot make moves properly, either on the game board or the analysis board.
I can press to select my piece ok, but the press to place it somewhere else seems to result in totally random placement. Sometimes the whole board lights up blue-ish as if it's been highlighted.
Things work OK if I swap to the board type for legacy browsers, or use the Mobile site ( but then I'm missing the Analysis board!)
Does anyone else use this browser from a mobile to play on the full site?
