At first I thought we were deep, then I read a little more and noticed we're not really deep.
I'd bet smaller OTT, we want to encourage the flush and straight draws to stay in the pot (AxJc, AcTx, hands like that), so smaller bet size really does that. Maybe a bet of $7. That way we can still shove most non-club non 8 or T rivers. And if we're shoved against OTT, I'd call. We'd be getting ~3 to 1 on a call and we're somewhere around 20-25% against flushes. However, we're way ahead against pair + draw type hands.
