Like? Dislike? I'm also just picking up Omaha so is folding preflop a better play? Villian not potting this makes me feel like he almost certainly doesn't have AA. He's talking a big game in the chat like he plays 300/600 or something retarded.

CO is obv donk and never has anything here unless its 88, 55 or 67 that hes calling with.

So you're saying the only hand you think he can't have is AA? You've just named the only hands that can call you. You can't tell if he has something or not here.

Preflop is standard.

I don't mind the flop bet. Lets you know cheaply if you are good, and stops some hands from outdrawing you. You always have backdoor diamonds if you get called.

At those limits, the re-raise to your raise is almost always aces, especially when he checks the flop with the ace, regardless of his position (SB).
