I would assume his range here on the river was a slowplayed T, or some other PP he floated with and filled up. It was among first hands at table of course so I had no stats or reads.

I just can't see this being a bluff after I two barrel and there's no draws that could have missed. The only hand that might play this way is JJ that I beat

It's close, You only need to be good like 30% of the time to breakeven. Folding or calling is good, but I lean towards folding just because at the lower levels this is going to be a T so often

You can't really do much about this, but as played you got to call im afraid.

I posted a hand that was exactly the same as this one. I had QQ, I fired out 2 barrels and then villain donked the river at me. It was a much smaller bet than this example and I was getting pretty good odds so I made the call and he flipped up trips. I feel like this is a T or a flopped/turned boat a ton of the time and you're only getting 2-1. I fold because this line is sooo typical of a big hand.

I'm not saying your wrong, but why do I have to call? I've only put in less than a quarter of my stack. I don't think I can feel committed and his line looks pretty strong.

Overbets are almost always the goods at these levels. Expect TX or a boat about 95% of the time.

How much of your stack that you've put in is irrelevant, it's all about the odds the pot is offering you in relation to how much it is to call. In this case you need to win 30ish% of the time for the call to be break even.

tough spot but I think Im folding - river pot odds arent good and with no reads I save half my stack here by folding...
