25-50 NL-- Standard fold?

[Rococo]

25-50 NL. This seemed like a very obvious fold to me but a friend thought it was close.

Effective stack sizes are $6K. 6 handed. Games is weirdly passive preflop at the moment.

Preflop

Dufus minraises to $100 in EP, which means nothing. I call in the CO with 7 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/club.gif[/img]. Very strong player on the Button calls. BB (a regular high-limit player on various sites -- seems OK) calls as well.

Flop is good for me.

Dufus checks. I bet $400. Button calls. BB pushes. I auto-muck. Easy, right?
