Bidding and Defense Dilemma
Board 2 has South opening 1NT 15-17 balanced.
North has immediate visions of slam in D's, S's or NT.
How to proceed?
Obvious firsts steps are to transfer to spades, showing a 5+ card suit.
Then North could bid 3D to show a second suit, 5-4 shape.
South sensibly signs off in 3NT. Nearly all pairs making 12 tricks.
Suppose North takes control and asks, finding 1 ace and king missing.
Now 6NT and 6S look suspect.
As it happens 6NT makes because West doesn't lead a heart.
