If that were a possibility, why would David Burn, who is not, so far as we can tell, a gibbering idiot, say that "3♠ ...is defined within the game as 'Stayman in principle, but if that's not what he has, he will have some other kind of game force.'" and that "North has no way specifically to ask you to bid 3NT with a spade guard"? Are you sure that the 3♠ bid was defined that tightly in the pre-game discussions? Are you sure that if you asked Zia whether a one-suited minor hand without a stopper might be 3♠ here, trying to get to 3N, he would say "No way!"? (And that would make neither David Burn nor Zia a gibbering idiot, nor would it tell us they are not world class.)
