It's a 2-5 game I am sitting about 1,800 deep, just won a big pot cracking a fellow's aces with pocket fives. I pick up aces in early position, raise to 25, and get one caller in the form of the person right to my left, every one else folds. Flop comes 945 rainbow. I lead for 50, he raises to 125. I think for a bit, mostly about the fact that in the three or four hours I have been at the table I have seen almost no one raise on the flop, except for the guy I just felted who had pocket aces. So I fold, figuring he almost certainly has a set of 9s, 4s , or 5s, or possible 45 for two pair. There are no real draws (67 seems s bit bold to raise, if he even calls with that). I felt good about the decision, but I wanted to make sure my thinking was sound. Was this too weak a fold? It's obviously a super exploitable fold, if someone had the brains and the balls to do it, but I doubt you see much of that at the 2-5 level. Thanks for your thoughts.
