UTG REG, CO FISH. When utg checks I think He is x/folding frequently vs 2 players oop on this board. I think I should bet this flop after check even if fish is behind me with this hand. I have TP, BDFD, 2 overs. When He calls I decided to bet again on K. This card hitting mine range more than fish calling range and I turned FD. Do you bet river without any reads? Only read I have He is playing 1 table. Do you bluff on blank river?
