Modified Swedish-2NT where
1M - ??

Splinter Raises
3D! = ♣ shortness
3oM! = ♦ shortness
3NT! = oM shortness

1S - 3H! - ( DBL)
p - RDBL = ♥A
3S - 4S = no ♣ Ctrl or ♥ K
4NT - 5S ( 2 + ♠Q or extra length )
6S

Why praytell would South keycard with a void? As a side note, this auction is no different than 1♠-4♦-4♠ except that opener has even LESS reason to bid on now.

Praytell, did you notice that Responder DENIED a ♣ Ctrl.
Thus, regular RKC ( 4NT ) is OK; "Voidwood" not needed . ( Sorry, I thought that was obvious ).

If my hand is ♠KQxxx,♥xxx,♦KQJxxx, i must bid 3♣and deny decent opening hand instead 4♣which promises void and decent opening hand.
After 3♣prd can ask my shortness with 3♦bid and now i can tell shortness in ♣ by bidding 3Nt. After that start he probaply would not take us higher than 4♠.
And yes KOJxx, xxxx, AQxx is opening hand in our system. Bidding goes on as above.
What comes to u last 2 hand examples gnasher yes then bidding goes to slam im afraid, but nobodys prefect at least not us .
After prds 4♦cue bid i cant do anything else than bid 4♠with 3 losers in ♥.
