Here is a hand where I called down an overbet bluff with 2nd pair. ($2/$5 NLHE full ring cash game in Venetian)
Guy in mid. position open raised $20 and I called on bb. with KTo. Flop T84, he made a continuation bet of $35 and I called. Turn 5, I checked and he checked behind. River J I bet $40 and he insta shoved $450 into a $150 pot. I called and he showed his bluff.
Here is my thought process:
With the big river overbet he was repping a hand like 79 or Q9. If he had 79 I would expect him to double barrel his double gutshot on the turn most of the time. If he had 2 pair instead he would at least consider a value raise instead of insta shoving all in after my 1/3 pot bet on the river. So I put him on a bluff or a straight. I kept staring at him trying to find out if he was scared. He didn’t move a finger, just stared down and looked nervous. After like two minutes I felt that he desperately wanted me to fold so I called with my KTo for second pair. He folded 66 face up and started to steam shouting ”Unfuckingbelievable” five times… #shipit
