My thoughts are, considering villan is TAGG and 'trys to play good' and seeing as he's OOP facing aggression - then unless he can get to showdown cheaply (which here he cant) then maybe he only really wants to go to showdown with AA (top set).

Most of the time here (when he doesnt hold AA) He is OOP and wants to win the pot post flop without a SD, but here he's facing aggression. If he has to get to SD than he's gonna need some good player reads (on you). does that make sense?

"TAggy is playing for stacks, Fnord is not. Discuss." -What does this mean exactly? If this means Taggy is willing to get his stack in with TPGK then surely running a bluff here is looking like -ev.
