Hi all

I was north here and I didn't understand the redouble here by my pard.
My confusion here is why redouble instead of 2h?
What redouble mean for you if you play with a pick up pard?

thank you for your advice

Hi,

most likely he wanted to show some strength,
direct raises are weaker.
Redouble is dangerous, but most of the time you
can control the auction.

With kind regards

After the double, there are a lot of 4-6 pt hands you'd like to raise with to impede the opponents and let opener compete if he has extra shape, knowing you have a fit. If you are raising this light, making the same bid on 10 makes evaluating whether you have a chance for game difficult.

It's a bit on the border here for a redouble but it's probably the best choice in a partnership where this is undiscussed. More advanced partnerships might develop sequences to show all 3 ranges of non-gf heart raises; 4-7, 8-10, 11-12. This often involves artificiality over the double.

Redouble should usually be assumed to be either:
10+, 4+ length in 2 other suits intending to try for penalty
or
10-12-, 3cd support (4+ if minor), intending to support partner's original suit at cheapest level.

Your partner evaluated his hand as a limit raise for hearts, and so redoubled first, and then raised hearts. I think his hand is not worth a limit raise, only a good 2♥.

Hi,

My pards and I play that redouble is to penalise the opponents in whatever they land in and tell p that your partnership have the clear majority of the points and that we have no fit ourselves. If this gets passed, new suit by opener is just to run away. I'm fairly sure this is standard.

Recently we thought we might try this approach after doubles (haven't tried it out much yet, so don't know if it works well or not, but I think it will):

Raising the suit is always obstructive to opponents: 2H on anything with 3 hearts, 3H on anything with 4, 4H on anything with 5 hearts. Should have some distribution in case we get left here.

1NT, 2NT, 3NT are normal raises in the suit: 1NT is a normal 2H raise, 2NT an invitational raise and 3NT is a GF raise. Opener can sign off if they would have passed it or say something else if they want to.

Anything else and you pass, then bid on your next go if you like, for example,

1♥ - X - pass - 1♠
pass - pass - 1NT - pass

shows a normal 1NT response (should have stopper but might not). A 2NT response there might show 10-12, not support for hearts but didn't have the right shape to make the redouble.

Agree with Stephen Tu.

North showed 6 hearts with his 2♥ bid so South can raise. Without the 2♥ bid, it becomes more difficult for Sourth. He hardly has enough offense for the 3-level but he doesn't want to conceal his support either.

North must pass opps 1♠. Maybe he reasoned that he would not sit for 1♠ doubled so he had to bid now to show his weakness. In that case he could bid 2♦.

I don't regard this hand as a xx because my suits are not good enough to penalise the opponents. North should not have bid 2H with a minimum and a 5 card suit.

[whereagles]

Rdbl by South has the problem that if auction comes back to him in 2♠ (as it did), South would be a bit too high for action.

Still, opener's 2♥ is rather redundant...
