Hi everyone, I would like to hear your thought about the following idea I just had (sure many thought about this before)
1X- 1Y - double - redouble is common to play Rosenkranz which shows something like HX in Y asking to lead our suit.

I wonder if its not more efficient to play this redouble as showing support for partner but prefer partner not to lead this suit.
example
1C-1S-D and you have

xxx
kxxx
KQTx
xx

I think playing Rosenkranz redouble and a simple support message to partner is too close to each other, and the anti lead might be better.

I guess if you play this anti lead redouble and you have the KX in partner suit you can sometime raise it.
what do you think ?

I don't like it.

Let me raise to 2S when I have support, let's not hand the opponents the entire 2-level.

Don't force me to raise on a doubleton.

Don't waste a perfectly useful redouble for lead purposes when we are only at the 1-level and it could easily be our hand.

I'd like to redouble on xx xxxx KQ10x Axx: competitive values and doubleton support.

Rosenkrantz is fine in my overrated opinion.

Rosenkrantz is not overrrated in my fine opinion....

I like Hans reasoning.

but I meant it as Hx of course, NOT Hxx.

I hear it's good to play redouble as 8-10 with doubleton support.

If you play Rosenkranz doubles and redoubles, you might consider playing Reverse Rosenkranz doubles and redoubles. In Reverse Rosenkranz, you make the double or redouble with support lacking a top honor, and raise when you have the top honor. However, in this variation, you generally have real support for either the raise or the double/redouble. So you lose the ability to show honor doubleton.

The logic behind Reverse Rosenkranz is that you are more likely to want to penalize the opponents (double, not redouble) when you have your values outside of your suit rather than in your suit.

I played Rosenkranz and Reverse Rosenkranz for some time, but have given it up. I did not find any real advantage to it over other uses of the double/redouble.

Been playing transfers (staring with xx) over these one level negative doubles, and they seem to work well. You can show a lot of different hand types and differentiate between a constructive and weak raise. It isn't quite as important as playing transfers here as the sequence of 1x - (dbl) - ?, and I could easily be convinced xx should be something other than a transfer to the next strain.

Overall I like lead-stopping doubles, as long as they are very well defined. I've had some poor results when partner thought they were on and the other partner didn't.
