Today's North-South can make 3NT, but only if they arrange for South to be declarer. If they "wrong-side" the contract, making North declarer, a spade opening lead sets up four spade tricks for West while he has the ace of clubs as an entry. But if South is declarer, a spade lead from West is not immediately fatal. "Right-side" situations are common, and expert pairs have agreements to cope with them. When North cue-bid three spades, he promised (by agreement) a trick in spades, so South had an easy 3NT bid. Some pairs might agree that the cue bid would ask South to bid 3NT only if he had a solid spade stopper.
