In a Precision-like system we play XYZ is off after ANY interference, before or after responder. After 1-Dbl responses are one-under(Rbl=)and jumps to 2M still show 54+ less than inv/inv; after 4th hand interference supp Dbl/Rbl are on. The whole structure makes XYZ less useful in competitive sequences. When XYZ is off, 2 and 2 are both natural NF, 2NT and jumps are invitational, and the 2 of the other Major is a general GF. Only one exception: when responder shows 4+s and opener shows 4s, 2 becomes 4th suit forcing as no “other Major” is available.

I would never consider to give count in my own bid long suit. My choice is “other” because i would play smallest to encourage and middle/high as sp.

In my precision partnership East's double is clear-cut. We have a very simple (and, in my opinion, effective)agreement: east would bid as if North had opened 1.

A partial solution to rusinow vs. suit issue (doubleton honor leads)is the one adopted by Meckwell. They lead rusinow only from naturally bid suits and from major suits implied by a t/o double (i haven't found notes about the last but saw it in some vugraph hands). I find it a smart compromise and am somehow surprised to see very few high level pairs to play this. Maybe i'm missing some reason, other than a memory strain that shouldn't be a problem for serious partnerships.

Choice of games makes little sense as opener's jump raise is unbalanced or 5422. Both serious or non-serious are not useful facing a strictly limited hand. 3N then can be shortness ask, turbo-like (slam try with defined number of keycards)or whatever you want other than cog or serious/non serious.

I prefer to play that responder's second bid after a Jxfer shows the suit above (2N for clubs…etc.). Consequently my answer is B. After 2 xfer to hearts, responder's 2 shows invitational values and it is more flexible than natural 2N (allowing to stop in 3 of a side minor when opener holds only 2 hearts). Note that this use of 2 allows to get more info below game also in case of 5H332 quantitative slam try, making the jump to 4N unnecessary.

Typo is my bet.

Gazzilli applies exclusively after 1 Maj opening and 1 or 1NT response. Treatments for strong hands after 1 minor opening are widely used in italian systems but they are never called Gazzilli (two “z” and two “l” is the correct spelling).

Responding to a question sometimes we choose one answer in a very convinced way, other times we choose an answer as well but we are less convinced. My comment just meant that my response was a strong 3) option. That's all, sorry if that could hurt someone's feelings about the LTC.

I'm happy with having never used LTC in my life, never tought of using it and never taught it to my students.

Georgios, thank you for posting this document. I find it very interesting and containing a precious set of examples. I specially appreciated the notes about what different bids would have meant in the given context. Very well done. Could you please tell something about the source of the document? I'm asking because it doesn't fit exactly the Big Bang notes that Norberto himself gave me as a support for commenting on 2013 Bermuda Bowl vugraph. Probably yours is a more recent version, could you please confirm?

@Ed over 2N, the impossibility to have both regular and puppet stayman available makes it necessary to cope with both majors in responder's hand. Hence the 3 rebid showing at least one 4-card Major, or another structure such as the Romex one. Over 1N the situation is different as 2 regular stayman can be used when responder holds both majors. That allows to play 3 as a modified (= simplified) puppet stayman, aiming not only to find a 5-c major in opener's hand but also to look for a 4-4 major fit giving away less info about the closed hand in case no fit is found.

Why Gil? 2 is regular stayman containing also invitational hands (and even weak hands if you like to play garbage stayman). Am i missing something in your point?

No need to respond 3 to 3 to guarantee a 4-card major (like it necessarily has to be done after 2N-3 puppet) if responder to 1N simply cares to use regular stayman when holding both majors. The opener then responds 3 to 3 just to deny a 5-card major - usual puppet development following - and if a major fit is not found, less info has been given to defense.

Simply bid 2 with GF strenght, dbl with less than that. What cards qualify for GF it's just a matter of hand evaluation and partnership style (how light an opener can be). Choosing 11,12 13 or 14 hcp as a minimum makes no much sense imo.

Art, could you please explain the reason for playing two different treatments according to who will be declarer?

The hand is slightly too strong for a splinter imo as seventh heart is a big asset and Q's are not necessarily soft values facing a strong NT. I would prefer to have a way to set hearts within 3 level, and would just stick to it. To have this option available is one of the reasons making 2nd round re-transfers a good choice (stayman then 2 for invitational hands with 5 spades).

“I think the ‘stopper’ stuff part of Leb is a leftover from when Double was penalty”. That sounds 100% right to me.
