Hi,

I do not like the call with KQs against a raise with an UTG limper. Looks like trouble to me. Reraise or fold.

My flop line: Check

a. CO bets/UTG raises/well... its only one pair.
b. CO bets/UTG calls/call
c. CO checks/UTG checks/very nice! He is scared of the flop or slowplays a set. If he bets the turn call. If both check bet.

The river problem is homemade. You are building a big pot with TP+decent kicker. The board is wonderful for his core raising range AK/AA/KK/QQ/JJ/TT/AK/AQ/AJ. I think there is only little reason to believe that you are ahead on the river.
