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). Like similar conventional bids,
opener's artificial "Z" call in the XYZ sequence is
alertable. XYZ allows the partnership to explore game using low
level bids and efficiently find suit fits. The XYZ Convention
has 10 possible unimpeded bidding sequences:
|
1C - 1D;
1H |
1C - 1D;
1S |
1C - 1D;
1N |
1C - 1H;

1C - 1H;

1D - 1H;

1D - 1H;

1D - 1S;

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:

| 2C |

bid 2D which responder may pass or follow up with an
invitational bid |
| 2D |

except opener's reverse: 1H followed by 2S |
