i'm assuming you're setting us up for an epic beat? QQ or JJ/KK/AA hitting a better full house on the river?
I must say you have a good analytical sense. FYI, my river always sucks, in vary rare case I get favor from the Poker God LOL
How many winning combinations the other guy can have?
AA and in the river: A
KK and in the river: K
QQ and in the river any card
JJ and in the river: J
Any card from hearts and he has two hears in his had
What else he can have?
A good tell if they may have this pocket pair is did they 3-bet you pre-flop?? Not always but this can be a clue to their holding
May be this will help.
As you can see he was the BB so
In the pre-flop I think I gone with BB, he checked
In the flop he rose and I doubled I guess. I did not want to go big, I wanted to milk others to maximize my return and then he called it
In the turn you can see he placed 300 chips and it was my turn...
May be this will help to understand his moves in the hand.
