XYZ Convention - XYZ, meaning 3 successive partnership bids
beneath the 2 level is a forcing conventional bid (similar to
New Minor
Forcing and Checkback Stayman
methods). XYZ allows the partnership to explore game using low
level bids and efficiently find suit fits. Generally, the XYZ
Convention is "on" when responder's rebid options include both minor suits (2C
and 2D). The XYZ Convention
has 10 possible unimpeded bidding sequences:
|
1C - 1D;
1H |
1C - 1D;
1S |
1C - 1D;
1N |
1C - 1H;
1S |
1C - 1H;
1N |
|
1C - 1S;
1N |
1D - 1H;
1S |
1D - 1H;
1N |
1D - 1S;
1N |
1H - 1S;
1N |
Should the opposition enter the auction, XYZ is still on in 1
level auctions, such as:
|
1C - (X) - XX - (1H/S);
1S/N |
1D - (1H/S) - X - (P);
1N |
1D - (P) - 1H - (1S);
X Still on if Support Dbl |
After XYZ is invoked by opener, responder's bids are:
| Response |
Meaning |
| 2C |
Requests opener to
bid 2D which responder may pass or follow up with an
invitational bid.
Note: like similar conventional bids, responders rebid beyond 1 Notrump
is artificial and alertable. |
| 2D |
Game forcing, responder's
hand pattern not yet disclosed, leaving an abundance of bidding space.
Note: like similar conventional bids, responders rebid beyond 1 Notrump
is artificial and alertable. |
| 2H/S |
Showing a signoff bid,
except opener's reverse: 1H followed by 2S |
| 2N |
Inviting 3N |
| 3C |
Showing a signoff bid |
| 3D/H/S |
Game forcing, shape showing |
