A routine fold?

[Eeegah]

Reads: This table has been one of the most aggressive I've seen at Stars .25/.50. At least as far as preflop is concerned--action seems to slow down postflop, but the table still has maybe three LAGs and a borderline. The first seven hands I saw were raised preflop, but it had quieted down the last orbit or two.

MP2 is that worst kind of player, a tricky fish. He'll often checkraise any street, and will limp premium hands like AA. He has no concept of hand protection, however. I think he's a LPP with aspirations of becoming a LAG--he's been much more aggressive this session than his AF of .71 indicates.

MP3 is rather less dynamic, but is still a LAG. He's raised with things as low as K9o.

My intention was to checkraise here, both to force out MP2 and because MP3 has flat out folded to a checkraise before. Unfortunately it's bet and raised, and frankly I don't like the prospects of carrying a top pair marginal kicker to the river, especially when I'm not closing the betting and the PFR still thinks he's ahead. If I need to improve, I don't have odds to draw to two pair or a set even if it's not raised behind. Am I right to fold this?
