XYZ interference

[jillybean]

Playing XYZ, do you play it off or on over interference?

 

1♣ (P) 1♦ (1♥)

1♠ (P) 2♣/2♦ ?

[mtvesuvius]

I prefer to play it on as long as I can bid both 2♣ and 2♦, although I don't believe that is standard.

When can't you bid 2♣ or 2♦ in an xyz auction?

I meant as long as the interference wasn't 2♣ or higher. Badly worded I suppose :)

I do the same like the vulcano: XYZ whenever the interference didn't lift us over 2♣. So for example 1♦-(pass)-1♠-(Dbl)-1NT-(2♣) means XYZ is no longer used. You could use stolen bid ofcourse... :rolleyes:

Off whenever the opponents have bid a suit. The auction you give is a perfect example of why you would want to do that. We don't need 2D as GF because you can bid 2H, and you are more likely to want to bid a natural 2C.

1♣ (P) 1♦ (1♥)

1♠ (P) 2♥

Is 2H invitational or gf? You've lost the ability to show the 2 hand types if xyz is off. To get out in a minor we can use 2♣/2N and although we are a level higher I think it may be better than ditching xyz here.

Disagree with this a lot.

 

One of the main advantages to XYZ is to be able to invite at the two level after 2♣. You lose this by having to cue to show a GF - and I'm not sure how you would invite playing this way.

 

However, after 1♣ - 1♦ - 1M, as AWM has mentioned many times, it makes perfect sense not to play xyz, in or out of competition.

Playing XYZ, do you play it off or on over interference?

 

1♣ (P) 1♦ (1♥)

1♠ (P) 2♣/2♦ ?

I don't play XYZ ( although I should ) but one of my notes on it says:

 

" With or without competition it is always ON as long as we have bid 3 times at the 1-level. "

 

Therefore, it is ON in the auction you show.

 

However, if it went :

 

1♣ - (P) - 1♦ - (1♥)

p - ( p ) - 2♣ / 2♦ would be natural and non-forcing ... NOT XYZ .

For simplicity, in one partnership, we turn it off anytime there has been interference. In another, we keep it on only over a double.

 

Re: XYZ-2N. Puppet to 3C. Follow-ups are slam tries (some use these for very mild game tries below 3N, slam tries 3N and above). You should discuss the following auctions:

 

e.g.,

1X - 1Y;

1N -

 

(a) ... 2N;

3C - 3N

 

(b)... 2C;

2D - 3N

 

©... 3N

 

All of these should have meanings. You might use one as a general cheap quantitative invite, one to play (direct 3N, I'd advise), and one a mild slam try with some sort of shape and support opener's minor (if X is a minor).

 

Also the auctions:

1X - 1M

1N -

 

(d)... 4M

(e)... 3M

(f,g,h) ... 2C

2D - 2/3/4M

(i,j)... 2D

2X - 3/4M

(k,l)... 2N

3C - 3/4M

 

Here you have 9 bids to describe the length of your suit, quality of your suit, and quality of your hand. I think enough people use enough variants that it's just worth sitting down with pard, hammering something out that you'll both remember based on meta-principles about jumps and relays, and then -- if you really want to optimize -- come back looking for critiques.

I have the following agreement with two partners

 

The name, "XYZ" comes from this..

1x-(P)-1y-(P)

1z-(P)-BID

 

Where x, y, z can be any bids, as long as responder has a choice to bid 2♣ or 2♦. In fact, the way I play it, as long as responders second bid can be two of either minor, then xzy is still on. This includes hands where opponents have bid (responder must have made a bid or double at his first opportunity or XYZ is off). So 1C-(1H)-DBL-(1S)-P-(P)- xyz is still on. 1C-(1H)-Pass.... after this pass by responder, XZY is off forever. Also, note that most people don't play XZY after 1C-1D-1any, however, I do. Some people don't play xzy after 1H-1S-1NT, but again, I do.

 

 

I appreciate han's point about having cue-bid available but still I play this method by agreement with partners I have discussed this with.

I play that 1m - 2M is invitational, so I don't need to invite in the major at the 2-level anyway. And that is the only invite where not playing XYZ loses space, I can still invite with 2NT, 3C or 3D just like you would after ..2C..2D.

 

A persistent poster could probably still find some advantages for playing XYZ in this auction, but I think the advantage of being able to bid 2C naturally is more important in these competitive auctions.

 

Kathryn, as you can see from the above, I prefer the cuebid to be GF.

I play that 1m - 2M is invitational...

 

With five pieces?
