seemingly clear cut... or is it.

3-6 short handed, online.

CO & Button limp, SB folds. I have 57o on the BB. I obviously check. (Edit: I did not have the 5 of clubs)

Reads lets see. Not much, except that both the CO and Button like to bet and are pretty aggressive with anything, not much slow playing going on and there's been a decent amount of betting. My image is of one that I can fold but is aggressive as well.

Flop: TA5, only thing important is that there's one club, the Ace. the rest I don't remember nor is it that important (rainbow)

I check, other guy checks quickly, 3rd guy pauses for awhile and then decides to check which wasn't typical for Villian.
Sure he could have gotten up whatever, but that didn't seem to be the case.

Turn: Tc

I bet, other guy folds, Pausing Button guy decides to raise, I deliberate and call.

River: A

I check, He bets, Hero... ?

Before I hear you have 7 kicker, let's think about hand ranges and what you think villian has.
