You say -EV like you've done the maths. You havn't. But when you do you'll know that you'd have to be sure EARLY in the hand that you were beat and beat by an overset and not the flush. Only by him shoving early and you having a monster read can you get that.

Later the flush possibilities form too much a part of his range and you will have inflated the pot enough to get all in with +EV against his range.

That also means that folding is -EV BTW.

I don't mind you laying down winning hands but I don't think you should advise people to make mathematically incorrect decisions.
