All I can say about this hand with much certainty is that BB's flop play is damn weird. Bet 40% pot and then just call that monstrous raise?

I'm not really seeing how you can get value from the river here. You have two opponents to deal with, and their basic hand ranges on the flop were:

A) Set
B) Top pair
C) Draw

Sets don't fold on the river. Top pair could easily have turned into two pair, and even if BB somehow has exactly AK, he has to fear two pair from you at this point. Not sure how much you'll be able to get from either of them with top pair now. And if they were on a draw then they fold.

It's confusing that they both checked the river (it makes it likely your hand is good), but then again I found the flop confusing as well. Usually if I'm declining a free showdown, I'd like to have some sort of idea of what my opponents have, and here I'm pretty confused.
