Ducks = 22.

You fear exactly one hand here, and that hand is 55, and you shouldn't have to fear it very much. If villain played like that with 44, well, he needs a talking to. If villain didn't 3bet JJ or KK, he's got a terrible case of FPS and still needs a talking to, so they can be almost totally discounted. Villain was pretty stupid to be check/raising a flop of that texture with 3rd pair, especially to then call the 3bet, unless you'd literally be stealing, betting and 3betting while still holding any two cards. 55 is probably about as remote a possibility as KK and JJ assuming a rational villain. The most logical hands for villain are KJ, K2, J2, K5, and J5, and even those were donked pretty badly. A trifecta is virtually never the way to extract the maximum. You're beating his most likely holdings badly, and the chances of things that beat you are terribly small. I think I'd put in one last raise on the river and congratulate villain on his trifecta and brutal suckout.
