Noble - Are you folding JJ to 4bets when you 3bet UTG opens? Are you often stacking off?
If you're folding, then I think you're pretty much turning it into a bluff.
If you're stacking off, then I think you're gonna get dominated waaay too much vs an UTG 4bet/stack off range.
If you're 3betting fish, then that makes sense, both for value and for isolating. I'm just not sure about regs ....
