South opens 1♠.
North has a mountain, but there is seldom a need to jump-shift when using 2/1. He bids 2.

South's priority on her first rebid is to agree trumps if possible. Knowing North has at least a 5-card suit, she bids 3.

North naturally feels slammish, and shows it with a control-showing cue-bid, 4♣. Do not even THINK this might be Gerber.

South doesn't have any extra strength, but that doesn't matter. With South making a slam try she should cooperate by showing her control. It is important to realize that South isn't showing any extra strength, she is merely going along with North.

North asks for Aces and gets two. He decides to find out about Kings, if South happens to have three he will bid 7NT. When South shows just one North settles for 6.
This should be a good slam, needing only a decent ♠ break.
