Raise or call?

Preflop: seems like a loose passive game. You are in EP, and thus should use a larger size of 4-4.5BB.

Flop: Why do you think that raising is the only option? I think this is a pretty clear call. When someone bets in a multiway pot, his range is much stronger than usual. Thus, the relative hand strength of AA decreases, and when your hand is a medium strength hand, you should call instead of raise because fewer worse hands will call, and you might open yourself up to getting re-raised which would suck.

Turn: When CO calls, his range contains many monsters and some flush draws. Maybe the occasional overpair which is weaker than AA. I expect him to check back all worse made hands like TT and only bet a set or better. Thus we have an easy check-fold.

Thanks again, I was playing NL10 zoom and did not pay enough attention to how the table dynamics had shifted. I will try to be more focused from now on in regards to how the different players shift the table dynamic so significantly. My bet sizing is definitely off I agree. To be honest I just didn't think calling was an option due to how many players were in the hand I could see a couple of player calling but at the same time already saw myself as most likely behind. But I will definitely see calling as an option in the future.

Also I didn't note any stats so sorry from that.

Cheers

Well we need to pick the lesser of two evils. I'm not thrilled with calling, but

EV (call) > EV (raise) > EV (fold)

So I'm just calling, not because it's great, but because it's simply the best option we have. And this sticky situation was partially caused by the small raise size. I think if you raised larger it's much less likely that you get 5way action. Remember that your goal is to avoid multiway as much as possible unless you have some sort of hand with very strong nut potential (like AXs or 33) but often those hands also play better headsup.
