Is there some trick or just experience that helps you count combos quickly (hands I beat vs hands I lose to)....in real time....while playing live? I have no problem doing it off the table, but it takes a lot of concentration. Also, I feel stupid taking over a minute when its on me and I'm facing a small $15 bet or whatever. But, when I've done this work off the table, I've seen so many spots where I should have folded or raised, etc..., but couldn't do the math in a reasonable time at the table.
