Let's say MP2 has a set, he's definitely calling. Now we have 2 people all-in. If CO has the NFD, he's probably calling with those odds and less than $20 left so you probably aren't making him fold. I'm still not sure the NFD would fold even if the orginal raiser (MP2) does. He has an over-card with a flush draw and is getting almost 2-1 on his money with about $35 in the pot. He only needs 1.2 to call and I don't think most $25 NL players are sophisticated enough to even think that someone else has a FD and 2 of their outs are gone. But if we're looking at

[3c] or

[4c] they also have the SFD.
Just for the hell of it hypotheticals, although I don't expect you to be able to do this or even think of all the possibilities in the time you have to make a decision.

So, like I said, this could be scary in an unraised pot, especially after a raise and a call in an pot that wasn't raised before the flop.
