Derek's JJ hand is really interesting.

I definitely 3bet it preflop.

IMO, the guy's range can be pretty wide, depending on how capable we think he actually is. Check out Elky's book and notice what kind of hands he says to iso limpers with. I'm pretty sure Jonathan Little's book says the same thing. I think it's sort of popular right now to iso light in the early stages to chip up against fish. (Also a pretty effective strategy in live cash.)

I don't think checking back turn is as bad as you guys made it sound. It can probably induce river bluffs considering how wide (undefined) our perceived range is after we've chosen to play the hand this way (flatting preflop and flop). He can still have random whiffed overcards and Ax (see above regarding his potentially wide isoing range), and can also bet worse for value on the river.

I think we're usually only getting two streets, as he's going to find a hero fold with 88-TT if we bet turn and river (although he should be bet/folding turn with any overpair IMO…but as we see here, lots of players are too pot-controlly on boards like this).

As played, definitely raising river to get value from a poorly played QQ/KK/AA, although I make it smaller than Chris suggested. It might be hard to get him to pay off much bigger than a minraise since there's a one liner on the board, and it's also easier to get away from our hand, which, despite its massive absolute strength, becomes nothing but a bluffcatcher vs a river 3bet. (Even if he's a crazy **** capable of turning a strong hand into a bluff when he knows he's beat, it would be suicidal for him to do so in this spot. We can pretty much rule that out.)
