I have no stats on the players and no specific reads. I assume they are not regs because of stacksizes.

On the flop it suck when he ships here. I think it is still slightly better EV to call it off. I don't think checking is not an option because he will also have missed this flop quite some time.
The turn is not good obviously. Given it did give us a flush and that he will still fold some of the time (an over pair, a pair + over cards) I opt to ship it here.
If the turn is non-spade 8 or any 9 I should probably fold?
