Simply respond to a takeout double

[gnasher]

8-11 is a much narrower range than for a non-forcing 1NT response to an opening bid, which these days is about 5-10.

Nobody plays responses to t/o doubles as 5-10.

I didn't suggest that they do, or that they should.

I don't see how the 8-11 range "allows" for light doubles any better than a 7-11 or 6-11 range would. A wider range costs when partner is strong, not when he is weak.

I think the point is that a narrower range from one players allows for a wider range from the other. If both ranges are wide that is obviously problematic.

Somebody I know plays some kind of Lebensohl here:

(1M)-DBL-(Pass)-1NT is relay to 2C, weak or strong.

and

(1M)-DBL-(Pass)-2x is more then minimum: 7-9.

What do you think about this idea?

Agree with gnahser that these arguments are crap. There are good reasons to play a tight 1NT range here but whether you double light has nothing to do with it.
