The book "1984" used to be a cautionary tale;
Now it is a "how-to" manual.

I am curious to see how experts will answer this, but with none forthcoming, I'll take a stab!
It appears to me that hands can be constructed for partner making any of 3D, 3H, 3S, 3NT or 4C
the best contract!

Most of those are long-shots we'd be unlikely to achieve even when correct. But Redouble,
surely for take-out, gives us a chance to get to our best spot. Or would the unilateral 3 Spades
be better, since this is likely best no matter how few spades partner has? Pass could be best;
especially if East, somehow thinking the Double responsive, might rescue us!

Why didn't partner open 3 Diamonds, or a weak 2 Diamonds? (Because he has four hearts?)
He didn't make a Negative Double so he has little help for black suits, but are his diamonds
AQT98x or AQ8xxx ?

Summary: I don't know. I'm considering an epileptic fit to let a substitute figure it out.

Cheers,
James

I'm disappointed that no expert has advised us on this problem.
It seems to me that we may be able to almost reconstruct the exact hands
based on the auction! South didn't open a weak 2D: perhaps he didn't
because he has 4 hearts. West doubled an ostensibly forcing(?) bid:
He must be confident he can double spades as well. Most likely the hand patterns
starting from South and going clockwise are
1-4-6-2 ; 5-0-5-3 ; 5-4-0-4 ; 2-5-2-4
It makes a difference what partner's clubs are, and how good
his diamonds are, but it looks to me like we may take about 8 tricks
in either spades or diamonds.

Cheers,
James
