Hand 23 - 1NT vs 1 Major

This is chapter 23 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 twenty-third hand I generated:

	North ♠JT ♥74 ♦QT953 ♣A764
West ♠753 ♥KJT963 ♦J6 ♣T2		East ♠KQ4 ♥852 ♦K74 ♣KJ83
	South ♠A9862 ♥AQ ♦A82 ♣Q95

Dealer is South and everyone vulnerable.

Double Dummy:
3♠ can make by N/S
4♦ can make by N
2NT can make by S
3♦ can make by S
1NT can make by N
2♣ can make by N/S
1♥ can make by E/W

Analysis

If South opens up 1NT I think everyone else will "Pass". West is pretty weak to be coming in vulnerable. (Or even non-vulnerable!) This is where they will play.

What happens if South opens 1♠?

North will respond 1NT and I said South would "Pass" with 16 HCP.

South is better off playing in 1NT IF when North is playing 1NT East leads a ♥. But I don't think East will. So North will also take 8 tricks in NT.

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