Play 2/1,this 7♠ auction looks like gamble!
If you,how to access 7♠ reasonably?
After 4NT breaks in,how to inspect RKCB?

[SteveMoe]

Perhaps just a simple 5♦ as control-showing and suggesting a good hand with good ♥s and a tolerance for ♠s. Partner might control bid 6♣ next... then it doesn't seem so much like a gamble.

There might be extensions for Unusual/Unusual but none I play here. Even though 4N takes away RKB, control biddin gis still available.

after 4nt,double is suitable?
1H-/-1S-4NT*(m+m)
X -/-5C-/
5D-/-5H-/
5S-/-7S-/
/-//
How about this process?

[SteveMoe]

After the double of 4NT, were I East, I would be bidding 5 or 6♦ - I need to get in your way. Now how can North-South recover?

Double implies a desire to penalize. While I think your sequence is reasonable if East takes no action, South might choose to bid 5♠ or pass the double for penalties. After all NS haven't got a known fit yet.

Some think passing 4N then pulling shows extras (and North has extras) but East will again bid some number of ♦s. Are you ready to control bid 7♦ on the North hand?

The primes in North make me think that control bidding early is smarter...5♦ will get south to cooperate. Now when East bid 6♦ South can bid 6♠ and North can bid 7 holding the black Ace South doesn't know about.

? north has no idea south has more than a four count with four spades, he has no choice but to double 4N imo.

Yes - that's true. Perhaps the right path is indeed

x - 5/6♦ - 6♠ - Pass - ????

Sometimes Preempts work.
