MP2 is somewhat loose but the CO has played relatively tight over around 20 hands.

4 folds, MP2 raises to t127, CO calls t127, Hero??

the MP2 had made a few raises from this position in previous orbits then folded to my button reraise. However, I'm more concerned about the tight player in the CO. The SB was a calling station and the BB was somewhat TAG.

How often should I be squeezing here against a donk and a TAG? My gut instinct is telling me 100% of the time!

t625

Clear as day flat on the button.

You used to love 3betting, what happened.

In a squeeze opportunity situation Id assume we make more from a random CO than lose facing 4bet, its not vs utg besides.
I think 625 is a bit too large but 3bet camp as well most likely.

I lean towards calling.. our hand flops well but if you really wanted to iso i guess id make it 500ish to see what co does. Still like calling better.

I don't wanna 3bet the middle of the range of hands that I want to continue. 3betting polar makes more sense to me.

Have you stick to some golden rule? Even 3 way in vacuum?

100bb deep we should opt for playable hands as a light 3bets esp 3way.
Not thrilled to squeeze 75s and barrel off on high textures vs unknown opps.

I'm in the flat camp. Too strong to fold pre or turn into a 3bet bluff. Can't continue on 4bets despite having relatively high equity.

It's probably a mix. Maybe higher freq of flat > 3bet (not certain about that) but both are +EV.

i would flat and play a pot in position
