Did I analyze this right? 3rd pair considering river call.

[BrandiFan]

Ok, I may have donked this up. I'm not that experienced in ring games...
UTG has been opening liberally from any position and generally lagging it up. No read on button as he just got to the table.
My combo draw on 4th turns into a pair of tens and I think I am ahead so I put out a blocking bet which he instashoves over. I am thinking he would flat call if he had a K or J, so I figure he either has a boat or air and I am getting 4-1. I called, thoughts on all streets are appreciated.

What makes you think your pair is good initially? There's btw virtually no way he's bluff raising river this shallow stacked.

[BrandiFan]

I thought he wasn't calling turn with a gutshot, maybe a flush draw, if he had paired the K he probably raises the turn. Jacks probably bet the flop. If he flopped a set he gave 3 opponents a chance to hit the turn.

I expect he is a donk with AQ.

[BrandiFan]

turns out he was a donk with 66, not sure what he was thinking.
