re: Poker & ugly hand here 25nl wtf to do???
I think you can rule out him having the 8 or A/4. 8/8 is statistically unlikely, and he "shouldn't" be calling a middle-position raise with A/8 or A/4 in the SB.
That means a set of 4's is what's most likely to beat you here.
Since you say he bets when he has a hand, I assume he'd three-bet you pre-flop if he had A/A and he'd do more than check/call when he flopped a set of 4's. (Why check/call the flop and check/raise the turn unless the turn helped?)
I might actually make the TPTK call here. The check/raise on the turn tells
me he really liked that Ace. If the Ace helped him, you have him beat or tied.
I wouldn't *happily* call, but I think you're going to win or tie more enough to make $ (or at least recoup most of your investment in the hand with a tie). I think I'd call here, and expect to tie the pot and come out a loser because of the rake.
Now, if the guy was a tight-wad, I'd happily fold.
