Fold 2 pair? (thread re-post)

[LrdNikon]

Live $1/$3NL

I'm in BB with about $400

MP1 has about $140
...his play didn't impress me at all during the session. I didn't see many of his raising hands because he was raised off them after the flop.

MP2 has about $500
...has been really aggressive all day. Semi-maniac, but has shown down some strong hands.

I get Kc7c in the BB. Folded over to MP1 who raises to $9. MP2 calls, folded to me and I call (pot=$28).

Flop is K-8-7 rainbow. I bet $15. MP1 raises to $60 and MP2 makes it $120.

What do I do? If I call, I know I'll end up putting $20 more in for the MP1 all-in, and I probably have the rest of my stack at risk after the turn.

I'm thinking at least a set in there with the raise and the reraise.

I'll post results after I get some feedback. Thanks.
