decided to flat w KK opposed to 4b w no hands on villain, I made the assumption he's a reg though.
don't know the correct line in this spot I believed we were going to be x/raised on the flop and have to fold so x/d back and even though its a good board for our range, we block his AK, KQ etc
Then the river comes and we can rep jacks by calling turn so wanted to bluff river but though he could successfully x/jam river with nuts or bluff.
