Suppose South opens with 1 NT (15-17). After two passes, East doubles, showing possession of most of the remaining 23-25 high card points not held by South.
1NT P P Dbl
South has a flat 4-3-3-3 distribution, with no real suit preference (incidentally, I wouldn't open 1NT with a bare 15, preferring a short minor, with a flat distribution). Can he "redouble" for rescue"?
A NT bid severely limits the bidder's strength and shape. In this case, South is asking North to bid his longest (hopefully 5-card) suit as a form of "damage control." If North has a Yarborough (no high card points) will s/he likely interpret South's redouble as such?
Or is there too much of a danger (between reasonably good players) that North will pass out South?
Put another way, does a "redouble" in this context work like a takeout double, where partner has to answer unless he plans to play to punish the opponents) with a strong hand?
