Pre flop min raise seems OK given that it is suited. It is a hand that in most instances you either flop the world (nut flush, an underrepresented straight) or you let it go three handed.

Unfortunately for you the flop is an absolute cooler. You flop two pair, but unfortunately your opponent flops a better two pair. There is no way to avoid losing a pretty decent sized pot. You bet the flop, as you should since you have two pair. It seems like a dream flop. Villain only calls so you have no reason to think you are behind.

The turn is where it gets dicey. The 5 seems like a relatively harmless card. 2-3 got there but that would be incredibly unlucky for you. At this point you have reason to think you are still ahead. You have a decision between checking for pot control purposes or leading out one more time since you think you are ahead. I think it is 50-50 which decision to make, although if you are going to bet into what I think is a slightly less than 16 BB pot, perhaps a case can be made for smaller sizing on your bet. But I still think I am splitting hairs at this point. You still think you are ahead of his range given the fact that you have two pair.

But now villain hits you with a massive overshove. It’s a pretty polarizing bet. If he has the nuts, wouldn’t he bet only 18-23 BB hoping to induce a shove from you? On the other hand, why would he shove with a stone-cold bluff given that you have shown nothing but strength this hand?

So what could he have that would make him shove. 4-4, 5-5, T-T, A-T would all make sense and have you crushed. 2-3 would shove on the turn, but does 2-3 call both pre flop (maybe) and post flop (seems pretty ambitious given that only four cards will allow him to get there on the turn or river, and if he misses on the turn it’s pretty uncertain he ever gets to the river))? A-K seems kind of unlikely to me given that pre flop there was a min bet and a call before he called from the big blind (I just don’t him failing to iso/squeeze with A-K).

The only bluffs I can see him playing this way are two clubs (KQ, KJ, KT, QT), but does he really have enough equity with one card to come if you call his jam? It would be a pretty bold, aggro move, but you say you haven’t been at the table long enough to have an idea how he plays. You mentioned 6c, 7c, but I think that hand would make sense to call your turn bet but does he really want to spazz out all-in with just 7 high (yeah he has a ton of outs, but only one card left to get there)?

Based upon all of this I think 4-4, 5-5, T-T, A-T are strong candidates for his hand and have you crushed, whereas hands you are ahead of if you call are clubs that are not as likely but still make some sense and AK is a long shot as played pre flop but I suppose he could have been trying to hide the strength of his hand. 2-3 has you beat but that seems like an unlikely but somewhat possible hand as played. Based upon this I think there are more hands and more likely hands that have you beat once he jams than those that you are ahead of. When you think it through in this much detail I think it is a fold, but it’s a difficult fold. You have two pair and if you win the hand you have the chips to do serious damage. In real time I think it is a very difficult fold to make. Given 20 minutes to think it through as I have done here I think the conclusion is to fold, but in real time I don’t know whether I find the fold button or not.

The saying is never go broke without at least two pair. You flopped two pair without a flush draw reached and without many straights having gotten home when all the chips went in the middle. This was a very unfortunate runout of cards. After the fact when you know the cards it is easy to say, hit the fold button. But over the long haul, is it +EV or -EV folding two pair on a board that is not horrible? I don’t know.
