xyz or 2 way checkback

[mike777]

Asking for feedback..not fee back lol.

 

 

Please assume 1 minor=2h shows less than invite and 4+h and 5+ spades.

 

Please assume

case 1) xyz

case 2) 2 way checkback, 2c=invite and 2d=game force. Very close to xyz but a bit less fancy.

 

1d=1s

1nt=?

 

a*) Do you prefer partner show 4 hearts or 3 card spade support if you use xyz or 2 way checkback now?

b*) What is the best meaning for 1d=1s=1nt=2h now? Invite or game force? Why? 5-4 or 5-5 or other?

c*) The point of question 2 is what hand types should we run through xyz or 2 way checkback and what hand types go through 1d=1s=1nt=2h? Please note 2h cannot be weak in this system here.

 

Thank you in advance.

too bad, if the 2H rebid can show specifically 5-5 and 7-9 hcp then combining this with the Bergen style CBS and cheaper suit jump shifts, you get to cover all major suit holdings up to 6-4 or 4-6 with 7+ hcp.

 

i prefer to show the 3 card support first

If u want to really smart u can also use the a reverse by responder as forcing, so a distinction between 4-4 or 4-5 can be achieved.

Use together with Walsh for xtra effect! (Makes it possible to hide majors)

eg

1C-1D

1NT-2H=5-4

while

1C-1D

1NT-2D

2H(walsh)-3H=4-4

Hi Mike, I play 1m-2H as Reverse Flannery by responder and very much less than invite (say up to 7 or so hcp). I also play xyz.

 

In a nutshell,

a*) Do you prefer partner show 4 hearts or 3 card spade support if you use xyz or 2 way checkback now?

 

Over 2D, I prefer partner to show unbid four card major.. note, 1C-1H-1NT and 1C-1D-1NT both can hide four card spade suit. Also note, most don;t play xzy after 1C-1D.. i do.

 

b*) What is the best meaning for 1d=1s=1nt=2h now? Invite or game force? Why? 5-4 or 5-5 or other?

 

1m-1S-1NT-2H is better than immediate 2H, not forcing (say 8 to bad 10) and

1m-1S-1NT-2C-2D-2H is better than the delayed 2H (after 1S), and invite (say good 10 to 12)

 

c*) The point of question 2 is what hand types should we run through xyz or 2 way checkback and what hand types go through 1d=1s=1nt=2h? Please note 2h cannot be weak in this system here.

 

You might try 2H is invite but promises support for first minor, while 2C followed by 2H denies support for first minor. Or you might use 2H as retransfer to 2S with four hearts on way to signoff in 2S (with 64). But not sure those are helpful.

after 2d by responder i prefer opener to bid whatever comes first... in this case, he'd show 4 hearts before 3 spades.. if my first bid was 1h, he'd show 3 hearts before 4 spades

 

What is the best meaning for 1d=1s=1nt=2h now? Invite or game force? Why? 5-4 or 5-5 or other?

i prefer 2h now showing weak hand, i want to play in hearts or spades.. 5/4 or 5/5

 

The point of question 2 is what hand types should we run through xyz or 2 way checkback and what hand types go through 1d=1s=1nt=2h? Please note 2h cannot be weak in this system here.

oops, should have read this part first :)

Given your constraints:

 

(a) partner bids 2♥ with 4 (if you bid 1♠) before showing ♠ support.

partner bids 2♥ with 3 (if you bid 1♥) before showing 4♠

 

(b) after 1minor - 1♠ - 1N - 2♥: you could play almost anything, and I doubt that any one decent approach will be significantly better than any other.

 

How about this: both 2♥ and 3♥ show 5-5 or better.

 

i) 2♥ is invitational while 3♥ is a picture bid: slam interest, good suits, not much outside. Opener evaluates minor Aces and any major honours to decide on slam moves.

 

With 5-5 game and no slam interest, and not willing to pass 3N, bid 4♥.

 

With slam interest (or willing to play 3N), but more widely spread values, go through 2♦

 

With only 4♥ and invitational values, go through 2♣

 

 

or

 

ii) all invitational hands go through 2♣; jumping to 3♥ over the forced 2♦ with 5-5.

 

2♥ is at least game going, with spread-out values, 5-5 or better, but the kind of hand that can accept a 3N contract

 

3♥ is the picture bid, slam interest, concentrated values

 

4♥ is the game bid, no desire to play 3N

 

For what it is worth, I have played the 2♥ bid as 5+ 4+, with longer ♠ than ♥, no game interest... I play it mostly in a weak notrump context and the strength is defined as 'no game interest opposite a strong notrump'.

 

But I don't like it much: especially over 1♣, I prefer 2♦ transfer to ♥ and 2♥ transfer to ♠, either weak jump shift or game-force with good suit: allows right-siding of contracts. Sorry for the plug for my toy :D

Using xyz and xyNT, I prefer to make it easy and have the agreement that opener shows the HEART feature first (e.g. either 3 card support for responder's heart suit OR 4 card bagger if responder's first round bid was spades)

 

Showing the HEART feature first is an economical, space-saving way to keep beidding low, that helps clarifying both major's situation at the 2 level, unless you play a relay scheme

 

 

1) 1m:1S:1NT:2D (GF)

 

Now opener bids 2H if holding 4+ hearts, and responder- if not interested in hearts but looking for a 5-3 spades fit, shall simply bid 2S. If opener instead holds 3+ spades and no 4 bagger in hearts, he'll bid 2S

 

2) 1m:1H:1NT(can conceal a 4 card spades suit):2D (GF)

 

Now opener bids 2H if holding 3+ hearts, and responder- if not interested in hearts but looking for a 4-4 spades fit, shall simply bid 2S over 2H. If opener instead holds 4+ spades and no 3+ support in hearts, he'll bid 2S

 

3) I guess a relay system might work fine, with the consensus of partner :-)
