OK we flopped a flush

[Tony Montana 22]

CO is a maniac 50/24/1.62/100 & he and I have a bit of history, not a ton but a little, I rivered a str8 to his 2 pair a few hands ago.
He will get it in pretty lightly TPGK could be the nuts, but on this board he doesn't have to be good to have a spade. I insta-shove if he had reraised me on the flop but the 4 on the turn complicated things.
