I had just sat down on this table about 10 hands ago, and I have no PT numbers on the villian.
When he led the turn, I thought it was pretty clear he had a K, should I be raising on the turn, or should I raise his river bet for value. I was worried about KQ or KJ as those were the most plausible hands I could put him on when limp/calling UTG.
