Memory is huge. I need to remember the players you were playing against and the way they played. You dont have to have photographic memory but you have to have a decent iq lol
You need to understand concepts and theory of how to exploit opponents and some of the math that goes behind it. This can be learned off the table. I think your memory needs to be most sharp on the table to figure out what players are doing with their ranges of hands. Then you can take what you learned off the table to maximize your value against each individual player.
if you play online, it's important to know your odds... because you play so many hands and statistically your odds are good. In live games is much important to read your oponent... that's my opinion
