found this in my DB not sure what I think bout it
villain is 6/6 over 17 limper is 42/2
obvious ISO but really big made me think it was for value not just cos fish limped
opinions?

CO rarely has AA when raising this big, thought without reads we obv can't be sure about that, but when I see a raise of this size then it's usually always TT-QQ AK, which stacks off often enough to be 3betting him pre imo, especially after a raise of this size. 3bet pre to $1.60.

As played I call flop call turn call river to keep AK and other air he might have in his range.

Why wouldnt u 3bet him pre? Nit raises...and we have the 2nd best possible hand, and hes likely to stack off because he only plays the best hands.

Villain has QQ? I think thats the only hand that makes sense lol. He'll have JJ sometimes i suppose...idk. Call down is fine.

Looks ok but you should 3bet pre because he has a really strong range with that iso size.

i prefer to 3bet pre but i don't HATE flatting because we get the chance to keep the massive fish coming along and CO iso'd really big compared to both his and fish's short stacks so building a pot isn't as imperative as if they were both 100+ deep. on the flop now the fish has disappeared i think i like popping it up to $2.8 or something and callin any jam or jamming myself on the turn. though calling is absolutely certainly also +EV. i'd definitely just stick the rest in on the turn for value. it's unlikely he ever bluff shoves the river given stack sizes, so there is no argument for keeping his range wide. and he definitely calls our shove with more combos of hands that we beat than beat us, so stick it in and shrug it off the times he has us smoked
