Hand 8 -- 1NT vs 1 Major

This is chapter 8 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 eighth hand I generated:

Dealer: West	North ♠84 ♥A97532 ♦QJ ♣963
West ♠AJ973 ♥KQ ♦AK3 ♣752		East ♠Q2 ♥J864 ♦T9865 ♣AJ
	South ♠KT65 ♥T ♦742 ♣KQT84

Dealer is West and everyone is vulnerable.

Double Dummy:
4NT can make by E/W

Analysis

If West opens up 1NT, North will pass and what will East do? Do they have enough to invite?

I think they do. They have 8 HCP and a five card suit. If you use the Rule of 16 it will tell you to go.

So East will bid Stayman. South might "Double" to get a ♣ lead.

West will probably bid 2♠ since they do have a five card suit.

East will now either bid 2NT (which West will raise to 3NT since they are MAXIMUM) or bid 3NT themselves.

What happens if West opens 1♠?

East will respond 1NT and West with their 17 HCP will raise to 2NT. East will bid 3NT.

South will lead the K♣.

So this one I think the result will be the same. 3NT will be reached no matter what West opens. They will get a ♣ lead no matter what.
