Is this an easy fold? My thinking is that this would be a shove if I had a diamond, since at least I'd have outs against a set and a blocker against the ace of diamonds. I generally give $16 unknowns no credit at all early on, but this feels too marginal, am I right?

Calling is fine, IMHO, you're rarely behind to a made flush against slowplaying fish. I think you have to flip with the money in the pot. Occasionally you're dead but sometimes you are also not even up against a flush draw.

you only need to be good about 1/3 of the time, so call is probably best. i'm guessing you win this about 40% of the time.

yeah just get it all in I think. It's not the worst thing racing off your chips vs. a probably 12 outer or more.
