Against two basically unknowns. The only read is that they aren't crazy enough for me ot have a read on them in a couple orbits.

I think you can lay this down to the double bet on the turn. CO's waking up after calling all those flop bets is generally a pretty clear indicator of the nut flush (straight flush also wouldn't surprise me, or T9 I suppose in a "best" case scenario). Also note that even if you're beating UTG he likely has a large number of outs against you (4 to 10). If they both end up being maniacs then so be it, but I don't think they are often enough to justify a call down.

I'm folding this for the double bet on the turn as well especially given the fact you stated it "they aren't crazy enough for me to have a read yet.." and it's been a couple orbits.
