Nicely played. I still don't really like the 45s UTG though. Very few players at 25NL are observant enough and make any effort to put you on a range. 45/10 aren't thinking past first level enough to make this profitable. The 45s is only important in your range to add value to the other hands in it. The regs may be aware but most hands are going to end up against this villain. In the above hand If Villain was on the button, but the flop had missed you, would you continue to rep the Ace? If villain was observant he wouldn't call you with A10 in or out of position. Check position stats in poker tracker for these type of hands and check how they are doing.
