I am not so much interested in uses of redouble as a scrambling or SOS device. e.g after a penalty double of a weak no trump. I am more interested to know of the different ways a redouble is used in a competitive auction. After the opponents double in a competitive auction the availability of a redouble in ones armoury opens up the ability to give a more accurate description of your hand for partner to evaluate. For example a very common situation after 1♥ dble and you hold spades with a shortage in hearts. When do you redouble or when do you respond 1♠?

I would like to hear of some of your favorite examples.

Rarely! Whenever I have something useful to say, that I might not be able to show easily after XX and opponents finding a safe place (good opponents won't be too scared to bid 1♥-X-XX-3♦, especially if they are confident about each others doubling style), I would rather start showing my suits.

In other words, redouble usually shows a balanced hand (well, shortness in partner's 5-card suit obviously allowed/desirable), not just any 10+.

We play a new suit at the two-level nonfocing, so redouble could be a strong hand with a lower-ranking suit.

One of my favorite uses of rdbl is MeckWell's
1♦-(dbl)-?
rdbl=hearts
1♥=spades

I play transfers over takeout doubles starting with a redouble, and I like this treatment. A pass becomes a 2 way bid showing certain types of hands with either 0-5 points or 10 +.

This arrangement allows us to trap the opponents more often at the 2 level, and puts the doubler on lead most of the time.

I realize this doesn't answer Jack's question. Playing standard methods I'm less inclined to redouble (assuming I have 10 + points) if I have a fit for pard, or 5 or more in my suit. Its just too tough to catch up after a redouble, especially if our auction gets jammed.

A pet treatment is the xx shows a 2 suiter and 10 + points. It seems you have some real opportunities to penalize the opponents and you frequently have a misfit.
