3N seems a tad pessimistic to me. Partner is presumably 4=5=3=1 or, rarely, 4=6=3=0. Partner should have extras for this sequence. I should note that not everyone would agree with this, but this sort of sequence is precisely why 2H over 2D does not deny spades...if opener raises 2S by responder, over 2H, he has a minimum.
One of the subtle difficulties with 2/1 gf auctions is that it is still important to try to differentiate between different hand strengths. For me, 2S promises some extras...say a king more than a minimum. Then I add pulling 2N to 3D and partner absolutely has to bid 3S.
3N would be ok on say xx xx KJxxx AKQx.
Here, while responder should be careful not to get too attached to possible holdings for opener, KJxx AKJxx Axx x is a completely ‘normal’ hand for the auction.
Responder should also understand that opener, with a less suitable hand but still extras, can slow down over 3S by bidding 3N. 3S is not a slam force!
As it is, hearing 3S, opener knows that responder has some mild, or stronger, interest. Opener knows there are NO major suit losers, and obviously no defender is cashing any clubs right away.
So opener can drive to slam here.
If my partner bid 2N then 3N, I’m passing...reluctantly but why contract for 11 tricks when partner shows 2-3 club stoppers and neither a spade Ace nor great diamonds?
But this is a great learning hand for the partnership, since bidding this intelligently involves lots of style issues
1. 2D shows 5+
2. 2S shows modest extras (or more)
3. 2N is a waiting bid, with no major fit and a reasonable club holding
4. 4D is patterning out, usually 4=5=3=1, but with the aforesaid extras
5. 3S shows the spade ace and says, in essence: hey, if you’re interested in slam, my hand’s not bad...responder could of course have an even better hand, but for now we are looking at the minimum that 3S says
6. Opener can slow the auction down over 3S (not with this hand) by bidding 3N. Say he held KQJx AKxxx Qxx x. Now he bids 3N and responder knows that the club Ace is a huge card and bids 4C. Now the decent slam is reached easily.
Note how both partners played a role in the auction, with neither taking over, or making final decisions, until after the partnership has reached 4C (on the 4=5=3=1 example)
