xyz when z is a suit

[pescetom]

I would phrase it the other way - XYZ was people realizing that their 2-way checkback system works well even when opener's rebid isn't 1NT.

 

But that's all semantics.

"That which we call a rose by any other name would smell as sweet”, as someone said. Although one partner of mine argues that this convention would have more success if it was called ABC.

 

 

(another good one is "what's XYZ-2NT vs XYZ-2♣-2♦-2NT? (potentially vs XYZ-2♣-2♦-3♣?)"

All clear to us:

XYZ-2NT is a puppet to 3♣, either weak with desire to play clubs or 2-suited with slam interest

XYZ-2♣-2♦-2NT is invitational to 3NT

XYZ-2♣-2♦-3♣ is invitational with Y and clubs.

That's one standard. And it's a good one.

 

There's another standard (which I play with my regular regular partner).

 

It is not good to have one partner think they're playing one way and one think the other!

 

That's why "check things out".

[pescetom]

Quite right of course.

 

More things to check out:
