With SPR ~10 I think c/c as you did is probably best; too often you'll be dominated. Since both your (perceived) ranges are wide, I think you're looking to play a small pot, realize your equity, and try to get to showdown cheaply most of the time. Which is kind of obvious since you have a hand that will rarely, if ever, dominate your opponent's, but can certainly be dominated itself.

Turn looks pretty tricky. With SPR 3.5, two pair, a flushdraw and a weak open-ender, simply c/f certainly appears weak. However, in my experience if an opponent keeps betting big when the most obvious draw completes, they usually had that draw themselves. Also in light of the overall game plan as described above, I think getting lured into playing a big pot might be unnecessary and a bit of an overplay.

Seems like a good spot to defend your blind.

I'd agree with this.
so x/call OTF seems best.
OTT w\ no reads I would probably fold. we don't really block any of value combos and as we do have spades it makes it a bit less likely that villain barrels draw hand.

OTF I prefer DonkBet. The reason it's because we have a hand that is too strong to xC, and not strong enough to xR. So I prefer DB flop and bet/fold turn.

Against this cap range: $fi50:((QJ,Ass,Kss,Qss,TT,99,55,T9,J8,876,KJT,KJ9,KJ5,KQT)) You still have advantage OTF, but you can't check/raise. So I prefer db easy easy

The way you played, against that same range, OTT you have 47% equity. But, I think his range is small now, like this: $fi50:((QJ,AKQss,AKJss,A76ss,TTss,99ss,55ss,J8,876,KJTss,KJ9ss))

You have 34% so it's very easy fold, because you have Reverse...
