An enticing hand, but RHO takes the wind out of your sails.
How do you proceed, with or without your conventional defence to Multi?

I would like to pass than bid 4 to be interpreted by partner as Leaping Michael's. + assumed other major Whether I can do this against the Multi I am not sure lol

In the absence of clever bids, X seems a good start. Far too strong for 3 imo, when a 4 contract would race in with very little from partner.

The first call is easy. I don’t understand any action other than double. While passing then acting seems superficially attractive, it’s important to remember that we have a partner. We might think that passing then bidding (whatever we bid) ‘should’ show this hand. Bitter experience of my own and lots of experience reading tournament reports has convinced me that partners very, very rarely work out our brilliant plan.

By doubling we announce strength….a common defence is that double is about 13-15 balanced or any very strong hand. By doubling and then bidding, even without a specific agreement, we show a good hand…just as if we doubled a natural opening bid then cuebid or bid a new suit.

So when in doubt, think about how our actions may appear to partner.

Our later actions may not be as understandable as we like, after double, but they’re almost always going to be easier to understand if we start by taking action rather than by passing.

As to what I do next time, that depends on how the auction goes before it gets back to me.

Btw, it’s common, when x could be 13-15 balanced, to play lebensohl by advancer over any of pass, 2H or 2S. We do not need to worry about 5C by partner…and if he did bid it, we bid 5D.

Good point on the Leaping Michaels. Chris Ryall's Multi vs Multi suggests a direct 3 to show this with 8/8.5 playing tricks and at least 54.

4 leaping Michaels showing diamonds + hearts. Delayed Leaping Michaels shows diamonds + spades. You could double then take action, but that comes with more risks. Most of those actions show a different hand type. We might have a slam on but I'm not sure how to get there. Maybe we should rebid 5 over partner's potential 4 preference over our LM.

Maybe double is safe after all. North doesn't know that South holds spades, so they can't raise the preempt even with a good fit without also having hearts. With our hand that's not very likely. So double, then 3, then later 4 might show something like this? Having the Leaping Michaels on the first round excludes most hand of this type from auctions starting with double, so maybe we're just torturing partner.

I thought multi versus multi was just a tool to 'punish' players for playing the multi, attempting to frustrate your opponents to the point they give up the convention.

In my usual defence against Multi, Double is a takeout of weak spades or any hand too strong for other responses.
My first thought was that 4 should probably be Leaping Michaels here (the bids above 3NT are undefined anyway).
My second thought was that with this partner I have no agreement about defence against Multi, so not the moment to fret about that.
I doubled.

In this excellent pamphlet he lists a direct Leaping Michaels as a fashionable adjunct (or feature?) of the standard ACBL defence (the whole defence is better than I remember from when I first read it in two slightly different variants: has it changed, or was I just a beginner?).

To be compared with the "ACBL" idea that direct leaping Michaels shows diamonds + undefined major (Advancer's 4 can be corrected to 4). Needs thought.

Having doubled as my standard with one partner I'm now stuck with a 4 response (no Lebensohl) and as West I will need to take it out to 5
Bidding 3 as Leaping Michael's style leads to 4 and if I believe that the slam is on then 4+ is key carding given that the other non- bids would have certain non-applicable meanings for me.

I'm not sure which is more modern. The idea is that with the boss suit we are more comfortable taking it slow, while ambiguity about the major is possibly expensive. Also with a minor suit + hearts we might prevent the third hand from finding a profitable 4 call.
The story starts to crack when third hand takes some action other than the 2/2 "pass or correct". Over a simple pass, 2NT or something else it is difficult to convince partner that we intended to show a Leaping Michaels minor+spades.

For what it's worth, my preferred defence against multi is the simple Dixon, although I require a 5-card major for an overcall and all my ranges seem to be one or two points different from Chris Ryall's page.

3NT by East, the Nespresso convention. Then West should find a 4 bid, and it's a pure guess from there but East might find it in them to cue the king of hearts, after which West can try 4NT ace-ask (there's never ambiguity with 4 key cards and a void). I'd settle for 6 on the auction, but you might try for 7. Placing the king of spades in South's hand on the bidding 6NT by East looks very good.

3N looks obvious. Wests most common hand-type, by a wide margin, is the 13-15 balanced. His holding 18+, when we have 13, is unlikely and he’ll take a call when he has that, since you’ve bid game opposite a possible flat 13 count.

What west bids is debatable. I think that 4D is forcing…west would pass with a ‘normal’ hand so 4D shows the big hand.

East has a good hand but better as declarer than as dummy due to the major holdings. Since he has a good hand, but could be off the AK of spades (west maybe xx AQxx AKQJxx Qx?) so it’s not 100% clear to bid slam.

Btw, my meta-rule is that if a player bids 3N as an offer to play, 4M on his next turn is regressive. This, imo, is far more useful, on a frequency basis, than using 4N as keycard. Maybe on this specific sequence that isn’t true, but this is a rare sequence and imo not worth trying to remember an exception to the rule.

So east is sort of stuck. If we believe that partner has shown 18+ (the standard acbl option 2 defence, which I play in one partnership), I think 6N is a reasonable gamble. But I may be influenced by seeing both hands.

Since we play lebensohl over the double and 2N then 3N shows the stops, we have a more interesting auction.

2-X-P-2N
P-3(too good to allow partner to play 3 natural, too good for 3 overcall)-

and now it's anybody's guess what happens, but I'd suggest 4N(too good for 3N)-5-6

Good question, I don't know the agreement.
The actual hand was weak with 3 spades and 2 hearts, as I recall.

I thought about it and decided I prefer your approach, ambiguity about the major makes for some awkward and cramped auctions while the developments with a known major are already there and work well. I'm just not sure what you do on the first round with minor + spades, do you pass or double?

Our defence against Multi is not that different from ACBL, but does not have the exotic feature of 2H as a takeout of hearts: we use it as natural 5 cards (as opposed to 4 cards implicit in Double). I would be curious to know people's thoughts about which is the better choice.

If my dear opponents are so kind as to let me show my heart suit at the 2-level over their weak two in spades, who am I to reject this gift? I prefer (2)-2/2 natural and 5(+), where hearts can be a so-so opening and spades needs to be a sound opening.
Personally I wouldn't tie a double to a Multi to any particular major suit holding at all. For me it is just a generic "partner, I have values and no bid, back to you!".

If Leaping Michaels shows a minor + hearts the hands with spades and a minor are supposed to pass, or opt for a 2 overcall (or double if all of those seem to be high risk). The latter two options give up on describing the hand in a single bid.

If your system involves passing some hands with values, this is fine as long as the multi has a strong option, if it doesn't (and is thus much more frequently passed) this can be dangerous.

Even the can-be-strong option can be passed without major headaches. It hasn't come up often, but I agree that passing with a strong hand with spades + a minor is a risk. Doubling is relatively safe if you agree that a bid at the 4-level shows the Leaping Michaels option. That does mean that you might have a problem with a strong single-suited minor hand on an auction such as (2*)-X-(2*)-P; (3)-?, where 4m would show the LM option. I don't mind choosing between 3NT, double and 5m there but it can get confusing.
