TP terrible kicker, nut flush draw. play it different?

Hey all, only real read on MP1 is that he'll play more hands than me and is therefore somewhat loose. Is my limp too loose? Is a river bet here reasonable? Is there a better way to play this? I'm drawing a blank. Thanks in advance.

Your limp is definitely not too loose. If you can't limp A5s at a .50/1 table, you need to find a new table. Excellent 3-bet on the flop, that makes me smile, because there are plenty of times I couldn't make myself do that. I think I bet the river here too, but I'm folding to a raise. What hands do you think he's raising here that you beat?

this hand looks good to me, i think i probably would have bet the river too. with his raise im guessing he hit two pair. if the table is fairly loose I think playing A5s most positions is fine
