You hold (W vs R):

♠ A 9 7 6 4
♥ A J
♦ 7 4 2
♣ J 8 7

Partner has:

♠ 10
♥ Q 10 5 3 2
♦ 8
♣ A K Q 10 5 4

You pass, LHO opens 2♦, RHO bids 4♦, if possible.

You've agreed on weak/strong Michaels over 1-bids, and you can infer them over 2-bids. The rest is up to you.

(I'll post our auction later; it was . . . interesting.)

andy beat me to it

I play leaping michaels as forcing althou not neccesarilly strong. A good question is if this sets up a forcing pass, then responder could pass to investigate if partner has spades and clubs, then he might try slam.

I play that LM promisses more then this, so 4 ♣ is out. Seeing both hands make 3 ♣ attractive.
But I do honestly not know, whether I would upgrate the hand to 4 ♣, bid my major or my best suit. I guess, with a passed partner, I would try 3 ♣ intending to bid 3 ♥ over a possible 3 ♦.

Andy didn't define what his 4♣-jump was called .
I think it is a Roman Jump ( the suit bid and the next higher unbid )... a type of "Leaping Michaels" for 2-suiter overcalls.

Another "jump" method I ran across sometime back for use over a Weak-2D is:
4D = majors
3H = ♥/♣
3S = ♠/♣ and
3D = stop-ask

[gnasher]

My 4♣ showed clubs and a major.

I prefer 3c over 2d the heart suit isnt that great
and the power btn the hands appears to be at best split
or in favor of the opps. 3c rates to be a lot safer and
keeps 3n in play.

after 4d it becomes apparent p has something over there
and I would bid 4h which should leave p well placed
to pick btn hearts and clubs though admittedly it will
be far from clear you have 5 hearts.

What is 4S? pass or correct or some kind of slam try? I think north not even trying for slam is pretty ridiculous, he has a monster hand esp opposite a diamond void which is likely at these colors.

[gnasher]

I meant 4♠ as pass-or-correct.

We're quite short of slam tries in this sequence - 4♥ and 4♠ are pass-or-correct and 5♣ is to play. That leaves 4NT. What do you think it should mean?

4♣ is a flawed bid since it doesn't immediately show BOTH suits as Leaping Michaels does over a weak 2Major.
That is why I prefer Roman Jumps over a weak-2D ( as in my post # 5 ) .

Now a 4♠ bid is clearly a Ctrl cue ( for trump suit,♥ or ♣, to be decided later ) .
5♦ = Ctrl cue
5NT = pick-a-small slam

I always played 4C as forcing, so it seems to me like pass should be forcing, or if pass is not forcing that double should mean something that is not penalty. I have never discussed any of that though.
