I like to raise 4xbb+1bb per limper, but 4x is fine too PF. On the flop, its a mildly drawy board, id like a bet of 45-50, but again, 40 is fine. Tun bet is fine. On the river, I like just betting enough to put him all in, I mean you've sized your bets great to get so his remaining stack is less than a pot sized bet. $1.10 is just pointless. You are gonna get called by worse Kings here a lot, and the flush draw didn't come in anyways. If he has a 9, then nh, and move on.

Well played at the least. Just put him all in on river.
