<font color="#CC3333">MP3 bets</font>, CO folds.

Final Pot: 12.50 BB

I know my preflop play might be a bit questionable, but on the flop was I correct to fold? I'm thinking I could be up against AA or AK and I doubt I'd get raised this heavily by anything but these two hands, or am I giving them too much credit?

Edit:
MP3 47/8.61/151 Aggression: 0.69/1.18/0.79
CO 25/10.29/68 Aggression: 3.25/2.50/2.33

hi. welcome.
you need to give us reads on your opponents.

while usually opponents will just call call call and thus we can label them passive, when we are faced with hand posts showing aggression we need more information about the specific players to give you good advice.
