Good push?

I had the 4 card straight flush, but in retrospect I could have been drawing dead as he could have already have had the flush. Do you push this one?

i like it. Folding equity + OESFD

Not my play on that flop.
But hey i like it if you hit your 1 out :P

no way i do this. this was the best possible realistic outcome hand wise, him having a lower set, and you were only a flip after the flop. everything else, namely any higher flush or flush draw, has you totally destroyed.
