3-bet? I didn't because I was looking for overcalls - bad idea when I've got such baby flush cards? Raise people out? Raise for value?

This hand is one of the few times I advocate a stop n' go.

Guess I'll throw my two cents in...

I think I 3-bet the flop for the reason that you identified... while you're holding the nuts at the moment it's a very vulnerable hand if a diamond falls and somebody completes their flush. Not that you could have known it at the time, but it appears that MP1 was on the draw, which good for you he did not hit.
