How much should H raise? V has $460 left behind. I think V has sets, straights, and flushes in his range. Maybe Q9. He called the big flop raise, so he either flopped a strong hand or otherwise likely hit his draw. If he has a flush, it is at best Jack high. Obviously, I want a call from him and not a fold... No-brainer shove, or min raise?
