I think your preflop and flop betting suck.

Why are you min-raising preflop? This is a classic donk move. You're inviting people into the pot, and this is reducing your chance of winning it.

Your bet on the flop is way too cheap. Anyone who has flopped a pair is going to hang around and try to hit two-pair or trips.

In a 200nl game I'm making it ~10 when I have aces, and betting at least $20 on the flop.

Your betting pattern with aces is going to be -EV long term.

If they want to stay in the hand, make them pay!
