What about heads up that confuses me whats a good hand heads up

whats ok to play?
When it gets to heads up, ANY PAIR!, Any 2 A K Q J Pretty much anything suited, nothing comes on the flop toss it . . . If you have any Online poker software installed, Check out the middle limit heads up Sit and Goes, (you can install for free )...... Then watch their actions. MOST OF IT will be advanced but you will see what cards they get agressive with and the choices they make... you may not get to see the cards if they muck but the board SHOUDL speak for its self
