Whilst the ability to 'tell' (deceive other players through facial expression) is quite a novel little addition, it would be great if you could discretely communicate with other plays with a little look or a nod in case you need to cooperate against someone going all in (as in this guide on
HoldemPoker.com).
I know it's sort of cheating but it's the best way to rid your game of those crazy Loose Aggressive players who are more often than not out there to ruin everyone's fun.
