1 ♣ 1♠
3♠ 3 NT (nat, serious3NT)
4 ♦ 4 ♥ (D control, no club control), club control)
4 NT 5♠ (KC, 2+ Q)
5 NT 6♣ (K, Club K)
6♥ 6 ♠

6 hearts asks for 3 round control in hearts. I guess East will just bid 6 spades, he does not know that his 3. heart will go on the 4. club...

Maybe, West is even strong enough for 4 ♠ over 1 ♠. In this case, East will surely gamble 7 ♠ after getting to know about the King of hearts and the missing King of Diamonds...
Kind Regards

upgrading west to spliner makes it a no brainer:
1♣-1♠
4♦-4NT
5m-7♠

East counts 5♣, 5♠, 1♥, 2♦. If west only has 4 clubs it will be tough, but ♣J+♥K save the day or ♥KQ... worse I can think of is ♣J+♥Q which requires a finesse so grand must be a good bet.

It is not an upgrade, but splintering aces?

1、1♣ 1♠后开叫方首先在要评估一下持牌的价值，在哪个区间，个人觉得高花有增值，低花有减值，无5张套，还在邀请的范围内。
2、如果开叫方跳叫3♠的话，就属于高度限制性叫牌了，以后就没资格作为主控方发动满贯。
1♣ 1♠
3♠ 4♣
4♦ 4nt
5♦ 5nt
6♥ 7♠
通常跳叫3♠为非均型或5422点力集中的半均型，通过开叫方答出♥K和自己的♣的持牌情况可以看出开叫方为非均型5431或4441，单张DA，大满贯机会多多。
