What would be your suggested schema when opps preempt with 2M after partner's intermediate 1C(any 13-16unBAL or 15-17 BAL)?

Thanks for any help.

Double is takeout
2NT is transfer to clubs, showing a good raise or better
3♣ is a weak club raise
Others natural and forcing

Some play that 3♣ is a transfer to diamonds (invitational or better), 3♦ transfer to hearts, etc. which may be an improvement.

Hmm this 1♣ seems very nebulous and pretty hard to use. You're probably going to get fixed a lot in competition no matter what continuations you play.

In any case, I'd recommend just bidding as though 2M was opened, except making responder's actions lighter by about an ace, with opener compensating accordingly. This has the advantage of being simple, and since you don't really have a great quantity of information more than you'd have over a first seat preempt it's probably close to the best you can do.

I assume this is part of a Magic Diamond type system. This is one of the weaknesses. For that you get to annoy the opponents with light 1/2-level openings many many times.

To the question: Treat this as a Lebensohl situation, similar to 1NT (2♠)

Yes Gerben, it is simple Magic Diamond system (in fact inspired with your version on web).

It is my plan to treat is similar to 1NT - (2M) with Lebensohl(or Rubensohl) in use, but because I have no experience in such 1C I wanted to asks players more "involved" in these methods.

Thanks all.

I also like to just act like there was no opener on such occasions. Works just fine, and sometimes, preempts just work...
