At what point do you slow down? Looking back, I should not have pushed the river. I could have been beat by 77/33/KK/AA on the flop and was just asking for a call. I was thinking I could be up against any other pocket pair, as well.... Don't want to go to $2 preflop because I want action and didn't just want the blinds. Please dissect....Check/fold turn--is that weak?
