I think Merry Christmas comes first.. wouldn't you agree?
Yes if you have a strong opinion that you are publicly advertising and if you don't wanna look like a **** tease-sure you should post the play in outcome of which you are confident.
Even though I gotta say- sharing the play prior often is like curse. You stay quiet about it, it will win. You share it and advertise it and it will find the way to lose! You already did the advertising part... so how can you possibly hide it now?
