7-handed, 1/2NL in New Mexico. My image should be very tight.
Villain in hand is possibly tilting semi-loose reg. A few hands ago, he lost $200 calling a turn check-raise from someone who called a preflop raise w/ A9o and turned top 2-pair. Somehow he had 43 (suited? unsuited?) in the hand, and another player asked to see his cards (laggy rec player w/ a cowboy hat). The two men got into an argument, and floor was called over. Floor ends up announcing that villain had 43 (she saw the cards), but cards were irretrievable in the muck after some shenanigans.
He rebuys for $200 and this is the effective stack.
2 limpers, I raise on the button w/ KQo to $12. Villain in the BB calls and CO limper calls. $36 pot.
Flop is Kc5s4d.
Villain donks for $9, CO folds, I call. Pot is $54.
Turn is 6s.
Villain leads for $30, I call. Pot is $114. (About $150 remaining stacks)
River is Qs
Villain leads for $30.....
Should I be raising this river for value, or is a call more prudent?
Should I be raising at any other point in this hand?
