Call or fold? Is this a close decision?

[damaniac]

So do we have a bdflush draw, or regular? I assume bdoor, otherwise it really isn't close. If MP1 had bet I'd make the call. However, MP1 checking is awfully suspicious (or maybe he has AJ or TT or something). I probably call anway without a read, as I don't expect most players to raise then c/r, I'm assuming he missed the flop and doesn't want to pay 2 bets to see the turn.

I'd also fold preflop to an unknown open from MP1.
