Reraise more preflop, 4xing the $25 to $100 would be the minimum (we have to account for the dead $50 in the pot, combined withour $100 villain is still getting 2:1 to call inthis spot...we can't give him even better odds
Side note I'd 4 bet light a bunch in this spot bc villains line looks so retarded (min raising after 2 calls giving the PFR and callers 5:1, 6:1 and 7:1 respectively) that he has a pot builder hand much more often than a huge one (unless we have some read that he is exceptionally bad or plays large pairs in this fashion)
On the flop JAM it. We have prior history that villain called down with 7s on a QTx board, now all of a sudden we're giving him credit for folding AJ,QQ KK here? (hint its 1/2 NL AND we have extra info on villain -- no way)
He bet less than 25% pot, we're probably popping him with AK here a lot anyway after this ridiculous bet, so why not include AA in our range as well even strictly for balance issues.
As played (flop) I'd shove the turn...
As played (turn) I'd shove the river. I doubt JJ (or even 99) would bet 125 instead of the full 260 (if that's the case he's braindead) and given preflop action we aren't too worried about much else
