Useful Good way to learn these common positions. Would be incredible if the opponents position was updated ands well then we could see if it's a double /redouble, drop/take. Then, the value of this app to improving your game would be immense. Updated to include different opponent positions. I just randomly discovered however that if you push on the left side of the screen under the diagram you get equity info for double take, pass and no double. This isn't clear as the is no button but this is a great feature
Not bad Not too good
