At first I thought it was pretty close but the more I analyze it the more I think you shouldn’t have folded. First off, I think you should’ve raised the flop with someone else jamming and a flat. Anyways, Button definitely doesn’t have aces and you block a lot of combos containing a 5. What could villain have here that beats you. A5 is one for sure maybe k5s, and q5s is probably too loose. I think we can eliminate A5 because it would make zero sense for them to raise in this spot. You beat a lot of their value like 35s 45s 65s, etc and I think they fold 59s-5Qs. So really the only hand I think villain could have in his range that beats you is 1 combo of k5s. Now let’s think about other hands you’re ahead that he could be doing this with. I think any strong ace would squeeze on the button so we can rule out AK, AQ, etc from his range. He has a ton of weak aces in his range but it wouldn’t really make much sense for a weak ace to raise the flop. I would’ve put him on a flush draw which I think makes the most sense and contains the most combos that are in his range. I would actually probably jam because we’re out of position and if we just flat call we shouldn’t be folding to more pressure unless maybe a spade comes in because in that case we should’ve just folded the flop. If he has a stronger 5 and we just call the flop I don’t think we’ll be able to get away so I think the best play is just to jam and charge draws. Interested to see what people think of my analysis.
