Thoughts on this very passive line? (tilt 6H)

[Bond18]

Tilt $75 6H, no terribly specific read on villain, seems averageish.

Blinds 30/60, villain is BB, i am utg+1 with A [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img]

Me: 3800
him: 5100

Preflop: utg folds, i raise to 180, folds to BB, BB calls.

Flop: A [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] (pot 390)
BB checks, I check.

Turn: A [img]/images/graemlins/club.gif[/img] (pot 390)
BB bets 233, hero calls.

River: 7 [img]/images/graemlins/spade.gif[/img] (pot 856)
BB bets 677, hero calls.


Thoughts here? Flop seemed safe/harmless and hard to get value from. He seemed content to bet turn for me so I wanted to let him keep betting, and by river i can't see him paying off anything if i raise so call seems standard?

You guys disagree?
