Mark and I were generally on the same page during the GNT's. Here's a hand that cost in our loss.
This is a week old, and I might have the black suits in West a little off, but this pretty close.
A few notes:
1. 1
♠ is unbalanced
2. 3
♥ is forcing, per xyz
3. We play kickback, so 4
♠ is supposed to be a cue
Some side questions:
1. Does 3
♥ 'set trump' in an xyz auction? Does it matter if the rebid is 1 of a suit or 1N?
2. How strong is 3
♥? Is it simply GF and shows great trump? Or is it a serious try but could have marginal trump?
3. Any comments on 4
♣?
In all of the versions of XYZ I know, 3H here is Very Good Suit, SI, whether O's rebid is 1suit or 1NT. 2D then jump in H seems to describe this one better, but what if O held stronger Dand C and weaker S? Another possibility is the variant that would go
1D-1H
1S-2C*
2D**-3S***
* = puppet to 2D, usually inv values
** = puppeting
***= self splinter with Very Good Suit.
Then if O's hand is stronger D and C and weaker S, you've taken care of that possibility.
