System restrictions:
Playing 2/1
1♦:2♣ 2♠ shows extra's (K+)
1D - 2C
2D (1) - 2S
3S - 4C (2)
4D (2) - 4NT (3)
5S (3) - 6S
(1) Since your agreement is, that 2S showes K+, you have to bid 2D
And the singleton oppossite responders long suit is hardly a
reason to upgrade, that the Queen of spade is a working card
opener does not know yet.
(2) cues
(3) if you dont want to bid 4NT, you can make a last slam try with
4H, opener will accept
With kind regards
