responder reverse

[000ffj]

What I really want to say is every reverse of responder must show 65 suits with invitation hcp and nf,It's completely different with the traditional usage,but It's more resonable for space.

1 Responder with invitation hcp must complete describtion of 65 suits exactly under 2nt.So only this way can complete this requirements.

2 with xyz style you always have chance to checback to find 4 cards of ♥ or ♠,so no need to reverse when responder has only 4 cards of ♥ or ♠

for exampl:

[hv=pc=n&s=skj974h8daqj742c8&d=n&v=0&b=1&a=1cp]133|200[/hv]

which one will you choice 1♦ or 1♠

1、if 1♣-1♦-1♥ how will you go on？and if 1♣-1♦-1♥-1♠-openner bid-2♠ then you showed your shape but this sequence is gf or nf?

2、if 1♣-1♦-1♥-2♠ and you must bid 3s to show your ♦6♠5 shape,but you maybe overbid with just invitating hcp

3、if 1♣-1♠-1nt after this sequence you can't describe your shape exactly,then both of you maybe miss 5/6♦.which one do you choice with xyz style if you 1♣-1♠-1n-2♣-2♦-2♠,you showed your hcp but your shape can't be shown enough

so how do you describe your ♦6♠5 with invitating hcp？

Responder must describe ♦6♠5 with invitating hcp under 2nt,becouse both of you maybe haven't fitting suit,but how do you realize it?

Maybe this way is ok,with xyz style

1、1♣-1♦-1♥-2♠=d6s5 invitation and nf

2、1♣-1♦-1♥-2♣-2♦-2♠=♦5♠4 invitation

3、1♣-1♦-1♥-2♦=gameforce checkback responder maybe with ♥4+ or ♠4+

Is it ok?

I play a xyz style "a la Hamman" where over 2♣ partner will puppet to 2♦ unless he has three cards in responder's major.

I consider this style to be superior.

 

So if I respond 1♠ I could continue with 2♣ over 1NT.

Over 2♠ --> 4♠

Over 2♦ --> 3♦.

 

However, I consider this hand too strong for 2♣. There might be no game but there might also be slam.

I would bid 2♦ (xyz) and follow up with 3♦.

I would not for even one second consider any invitational sequences for this monster. If partner has a heart-club two-suiter, then I may get us too high on the misfit, but that will not be a first (or last).

 

For much of my life, I would have always chosen to start with diamonds and reverse into spades (but we must be careful about our agreements re 1C-1D-1H-1/2S sequences). I have now switched to a more pragmatic approach to bidding 5M-6m hands. I tend to bid them as if they were 5-5 (i.e. major first even when minor is longer) unless we have some specific agreement. Too many times, the auction has gotten out of hand before I am actually able to convince partner that the major is really a 5 banger. So, I would start with a 1♠ bid intending to make a game-forcing call in diamonds next. If partner rebids 1N (I will be elated as now the misfit is no longer an issue) and we are playing normallish xyz, then a 3D rebid would seem appropriate (5S-5D, GF, values concentrated in long suits).

1c=1d

1h=1s(natural and gf/5d and 4s opener has shown 5c and 4h)

with less responder would start with 1s not 1d.

 

no problem yet.

[dake50]

You conflate two problems: GF v shape.

How do I know if I'm game forcing before I show this rare shape?

Fit makes slam close; misfit makes no game likely.

Show your shape, let partner announce his fit and going up, or misfit quitting.

I don't think any min/inv/GF can get out below 3-suit

- likely not liking this high on a misfit.

But must show this 6-5 because it plays very big on a fit.

Is that what you intended your question for? Which rebids scream misfit => quit?

Thus which others suggest fit => going up?

This is not standard:

 

1C - 1D

1H - 1S! ( GF, my be artificial; will next bid ♠ again if real suit )

2C - 2S ( ostensibly 4s/5d; any bid other than 2S would deny 4 cards ♠ )

2NT - 3S ( now showing 5s/6d )
