AJo 5$ NL, Top pair facing action

[frad]

Yeah, I knew this was going to be hard to play postflop. However, I was almost positive MP3 was coming along, most likely with absolutely nothing, which was giving me pretty good odds to see a flop. Would you suggest folding to his minraise preflop? That seems a little tight. I don't think not raising preflop is an option here either..unless my limit play is clouding my judgement.
