AK UTG against LAG - B&M

[pig4bill]

$5-$200 spread limit in brick and mortar casino. I have about $600 and other principal is fairly LAGgy with about $1000. He is on the button, which is a $2 blind in this game and I am UTG. Big and small blinds are $3 and $5.

I get AKo UTG and raise to $15. I get 5 callers including the button, who's range is unlimited as far as I can tell. From a stone cold bluff to AA.

The flop comes K 3 x rainbow. I lead out for $25 and 2 call, then the button raises to $75. He's been pushing people off hands all day with nothing. I call, everyone elses folds.

Turn is a 9. I check, he bets $75, I call.

River is a 10. No flush possibilities on board. He bets $200, which is the max in this game. I think it's entirely possible he has KQ or even nothing at all, so I call.
