I never answered the actual question, cuz I wanted to discuss different squeezing. But when I play live I squeeze em out my own way. I look at the first when it hits me, then observe the action at the table, and when it's on me squeeze the 2nd card.
Gives you some excitement without giving too horrible a tell. I used to make sure I didn't look at any till my turn, due to tells, and should be looking at others for tells too. But after a few hours I'd have a good idea of who plays like how, and could afford to do non-productive things a little, lol.
