$1/$2 NL 6 max

#1) Total fish limps UTG with a $140 stack. UTG +1 ($180) raises to $9. Im next. I cover them and make it $30 with [As]. UTG cold calls my $30. UTG+1 4 bets to $70.

OK, he has KK like always. Shove now or flat call and try keep UTG in?

#2) Read: Villain called a raise with QJ in the BB and led full pot into a QJ5 flop. Raiser raised and villain shoved and beat raiser who had a flush draw.

Few hands later...

Same villain limps UTG. I raise to $12 with [As]. He calls.
Pot $27. Flop [Jd][Th]. He leads $27. Anyone fold right now figuring him for 2 pair again?

Call and see what the turn brings?

Shoving anything...you've put SO much into the middle, that hero can't possibly make a mistake postflop by sticking it in.
