regarding Relays with Double-Barreled Invites

[straube]

I'm playing Adam's method. Do you have the right continuations?

 

1S-2C, ?-relay break = GI 5 hearts

 

1S-2D,

.....2H-denies 4 hearts, various hands

.....2S-5S/4H, minimum

.....2N-5S/4H, max

 

So GI 5H starts 2C but GI 4H starts 2D.

 

Not sure if your weak relay bears any resemblance but I got some feedback on a weakness signal here...

Thanks David: had adopted that over 1♥ but missed that it also applied over 1♠. Is there any further differentiation of opener's maximum hands? Does 3♥ show a max 55? Is 3♠ a max with 6S and 4H? (Both seem sensible to me.)

No. After either 1H-2C or 1S-2D, the 3H, 3S, and 3N rebids show max 534m1s with high, middle and low short. We follow Adam and Sieong there.

 

Now I'm not sure how they continue after 1S-2D, 2N (showing max 5S/4H) but I'm certain they have a mechanism to unravel that. It wouldn't surprise me if they use what we do because it's based on their NT structure.

 

3C-asks

.....3D-5/5 or 6/4

..........3H-3H

...............3S-6S/4H

..........3S-2S, not 3H

...............3N-5S/5H

.....3H-5413

.....3S-5431

.....3N-5422

 

I didn't want to interrupt your bidding session but if you're interested in feedback...

 

1S-1N, 3H with a 13 pt 5512. This imo should have gone 1S-1N, 2H-2S, 3H

 

1S-1N, 2D P with an 11 pt 1435 or something which should have rebid 2N. With 2 spades you'd rebid 2S and then let opener take another bid with a max.

 

1S-P with some 6ct 1534 which can bid and pass anything

 

We've pretty much agreed that 1S-1N, 2H-3H is a courtesy raise (like 8-10) and 1S-1N, 2H-4H is a limit raise. Maybe there's a better solution (false preference to 2S?) but I don't know what it would be.

[straube]

What do you play now after 1M is doubled? System on? Transfers? 1H dbl 1S is natural?

[awm]

Transfers from 1nt, 1S natural, 2nt as a strong raise with 4+ and XX as general values (usually no fit).

Thank you
