Redouble by opener

[bd71]

1♣-(P)-1♠-(X)

XX

 

Playing 2/1 if that matters. An infrequent partner and I had a disagreement about whether redouble here would standardly show [a] spade support or extra strength and no clear direction. Or is there some [c] answer?

Both styles [a]/ are playable, although [a] is better phrased as XX = showing 3 card support,

so that a direct raise to 2S showes 4 card support.

 

We currently play XX as showing add. strength, but we also play a weak NT, so the frequency of being

able to make the XX is ok, if you play strong NT, opener cant have the bal. 15-17 hand any more, so

the frequency for the XX drops.

As a consequence - in a strong NT system playing [a] will be more useful than playing .

 

It may also make sense to play XX as transfer.

 

With kind regards

Playing Support Doubles , this Redouble shows 3 card Sp support ( regardless of strength ); a Sp raise would show 4 cards with the level depending on strength.

The (old) standard meaning is probably cards, something like 18/19 balanced looking to penalize the opponents.

 

Almost everyone now plays support redoubles in this auction though. That's what I'd assume playing 2/1 without discussion.

[gszeszycki]

if you have not agreed to play support x xx the xx here will generally show an unbalanced hand with extra values (say 16+) with almost assuredly spades as a short suit or a more balanced hand with 18+. All of the other hand combinations are relatively easy to show via 1n 2c 2s 2n 3n or even 2d/2h.

At least in North America, support double is a very popular convention, but it is still marked as red (alertable) on the convention card. The way I see it, if we haven't discussed anything, I would not assume that we play any alertable conventions.

[Zelandakh]

Old-style meaning = strong hand with good defence.

Most common current meaning = 3 spades.

Another possible meaning is xxx in spades (with Hxx show support directly)
