Texas Hold Em is a five-card game, ALWAYS, NO EXCEPTIONS
"say if I have a 2 and a 3, suits don't matter on this..
and my friend has a 2 and a 5, and the community cards are an A, J, K, 2, and 7 - we both have a pair of 2s obviously, but he has a higher card, BUT since I can also take the A, as can he, then we split the pot...correct?"
You both have a pair of 2's with an AKJ kicker.
The other cards don't even play
