My play on the turn was marginally profitable
we have 14 outs assuming the ranges we gave villains,any A,9 or spade=14outsx2= roughly 28% Equity
You're assuming your A and 9 are always good, which they're not. And then there's rake. So it's less marginal than you think.

But I did say I wasn't sure about the turn.

The play you say to do on the flop is questionable.
Not at all. How much equity do you suppose you have on the flop? It's certainly more than you have on the turn, yet it's the turn where you put all of your money in. Do you not think there's something wrong with that?
