Good flop for AK?

[tempest7178]

5/10 SH game (sorry i couldn't find the hand history)
AK offsuit on the Button. UTG folds, MP raise, CO call, I 3-bet, SB calls, BB calls, MP calls, CO calls. 5 to the flop for 15 Small bets.

Flop is A A T rainbow

checked to me. I bet, SB check-raises, BB 3-bets, folded to me, I cap it. SB folds, BB calls.

Turn is a offsuit 6.
BB checks, bet, call.

River is an 8
BB check, I bet, he check-raises, I call.

comments? What hand does he have? Any other way to really play this?

I don't see another reasonable way to play it.

What does he have? A8 for the tight on the end? I can't believe he would play TT, 88 or 66 the way it went.

Anyhow I'm not folding so I'm not reraising and risking a cap.

He had TT for the flopped boat. After the flop check-raise and re-raise alarm bells went off but I figured/hoped the BB for a hand like AQ or AJ. On the river check-raise I was 99% certain I was beat but I wasn't sure if it was a hand like TT or an A8 or A6 kind of hand or if he was raising with a hand like AQ for value, so, of course, I paid off. Would you ever check behind with the seeming blank river?
