When you shoot the moon in pineapple OFC, do you get 20 points, but the other player always scoops you? or does your hand not get scooped because it shot the moon?
Since it is very hard to shoot the moon in POFC, other players do not scoop you if you get there. So you gain 20 points from each player.
Otherwise the risk you take would (by far) not be worth the outcome. (Imo, I think that 20 points from each player is still not enough to make this play profitable.)
