played it like a solver

This comes from practicing on the solver.

I would love to see a solver play 2nl...

Its ok, though after this hand I would always raise turn vs this guy. If he doesnt valuebet AA on brick like this then why he is overbetting in first place?

Congratulations on winning the hand! Let's analyze the hand and see if there were any spots where you could have made a different decision.

Preflop: You are in the BB with pocket fives and face an UTG raise. Calling here is a reasonable play given that you have position and the potential to flop a set. However, a 3-bet bluff or a fold could also be options depending on your playing style and the tendencies of the UTG player.

Flop: You flop a set on a coordinated board of 7c-4s-5c. You check to the raiser, who bets 3.6 BB into 5.44 BB pot. Calling here is the right play, as you have a strong hand and don't want to scare off your opponent.

Turn: The turn brings a 9d and you check again, UTG bets 18.96 BB, which is a little over half the pot. You decide to call again, which is fine given that you still have a strong hand and there is a lot of value to be had if your opponent is betting with a weaker hand.

River: The river brings the 2s, which doesn't change much. You check and UTG checks behind. While it is possible to make a small bet for value here, checking is also reasonable since your opponent is unlikely to call with a worse hand, and there is a chance that they may bluff catch with a hand like AK.

Overall, it seems like you played the hand well. You flopped a set, and managed to get value on every street by calling your opponent's bets. Your opponent was holding pocket aces and made a good preflop raise, but was unable to improve their hand enough to beat your set of fives. Well done!
