South can bid 5S over 4H as an invitation without any cuebids available. North can then bid 6C to suggest a place to play as it appears.
I evaluate N's hand as MUCH better than he said with the 3
♠ bid.(for me 1
♠ shows always 5 cards)),So if 4
♠ would describe his hand, then 4
♣ shows a 6 cards suit with 3 cards spade fit, isn't it?
It is like 1
♣-1
♠-4
♣ 6 cards with 3 cards support...
A 4
♣ bid without spade support doesn't exist.
So S may agree clubs with 4
♦ and 4
♥-4
♠ are available.
Why are we so conservative when bidding offensive hands and most of us agree to open 3rd vulnerable against not a 9hcps count with kqjxx spade
