5/10-Weird River check/raise

[sauce123]

converter not working

weak player UTG limps for 10

I raise to 45 in CO with AK

BB calls UTG calls

Flop: 783 r check/check/check

turn: 7 checks around

river: A check check i bet 75 into 140 BB checkraises to 360

BB is running 22/18 and is probably a winner, not that many reads otherwise, probably squeezes a little more often than most. im running tight today like 17/14.5 and have been showing down strong hands.

I would probably fold, I could see him do this with a A8 or a 7. And I really think he is just calling with a hand you beat here.

[sdv]

i call. at least 1st time.
He is definetly doesn't have A8, so the only hand is 7x, or 88 and i can't see him checking the turn (MAYBE w\ 88) .
also, your hand looks exactly like Ax or bluff, so he wouldn't expect you to call here.

bet more on the river

i'd probably fold because on average i think ppl are a lot less likely to bluff here when the pot is smaller(ie just the pf $) than when there has been a cbet or a turn bet.
