Tough call. I will go on and bid 4♠, showing a control and inviting partner to ask for key cards. Our hand is mostly aces and we do not have an unexpected source of tricks. I therefore want partner to evaluate our slam prospects.
An awkward auction. Preempts work.
Do you assume 3N is serious/non-serious or an alternative place to play?
