Hand 20 - 1NT vs 1 Major

This is chapter 20 in the story of my attempt to determine if it is better to open 1♠ or 1NT with 15 to 17 HCP and a five card ♠ suit.

The journey started with this post:
Later On

Here is the twentieth hand I generated:

	North ♠KQ986 ♥Q3 ♦K72 ♣T73
West ♠AJT75 ♥85 ♦AQ9 ♣A86		East ♠42 ♥AKT92 ♦JT ♣KQJ5
	South ♠3 ♥J764 ♦86543 ♣942

Dealer is West and everyone vulnerable.

Double Dummy:
5NT can make by E/W
4♠ can make by W
4♥ can make by E/W
5♣ can make by E/W
3♠ can make by E
3♦ can make by E/W

Analysis

If West opens up 1NT I think East will transfer to ♥ and bid 3NT. This is where they will play.

What happens if West opens 1♠?

East will bid 2♥ and the partnership will still get to 3NT.

If West opens 1NT they are likely to get a ♠ lead from North. But either way Declarer has 11 tricks no matter what North leads.

So I think this one is a draw. Really doesn't matter what West opens.
