r/r imps. 1N p 3N to you. It is a knockout match against an evenly matched team, you know if the auction goes the same at the other table your counterpart will not double (she is their client). You know your opps and your teammates play the same NT range. You know RHO is a pro.

I will double, asking partner to lead worse major. Double has more ways to win than to lose. Of course sometimes you'll be punished.

For an Obcessive Compulsive Doubler like me, this is a WTP.

Incidently, I'd never take the same seat as my opponents client, but leave it to a weaker player, like partner. :blink:

I would certainly double. I hope this is not because I'm over-eager to use conventions.

Light it up.

Loses when partner has no 4th round diamond stopper
Gains (a lot) when partner would make a disaster lead (very likely looking at our hand) and we could otherwise beat them

In theory this is correct. In practice this action never seems to work for me as advertised.

Lol did you like when you doubled some game yesterday and she asked me if that promised her suit, and I kinda just started laughing?

Double. I'll never get a heart lead otherwise.

This could be a bloodbath.

Agree with Dbl. They might have 9 top tricks, but them's the risks. It's worth it if you knock the vuln game. Without a dbl, pard is almost certainly making a lead that will help declarer.
The difference between theory and practice is that in theory, there is no difference between theory and practice, but in practice, there is.

I guess it depends on my agreements about double. As I've discussed this with Phil (it would definitely mean lead your shorter major), I would double. With someone whom I haven't discussed it, I'd be more hesitant, but still think double would be our best shot at a set, so double it is.

I agree, I'm just not sure for which side.

But I still double. Maybe one day I'll learn. Certainly partner is most likely to lead a spade without it, and that won't be very helpful to us.

I disagree.

I think double is a mistake.

If RHO has a strongish balanced hand than partner is broke and will be able to find the h lead all by himself, unless hes got something like 3H and Qx of clubs. If RHO has a long running D suit (likely imo) than X is just too dangerous.

Something not yet mentioned is that the pot odds are pretty good. Let's assume -630 from the other
table (of course if the normal defense beats this it's hard to see how double can hurt unless partner leads the wrong short suit).

No double -> push
Double (and no redouble)
10 tricks -> lose 8
9 tricks -> lose 3
8 tricks -> win 13
7 tricks -> win 15 (I admit this is a rare outcome)

Double and redouble
10 tricks -> (-1400) lose 13
9 tricks -> (-1000) lose 8
8 tricks -> (+400) win 14
7 tricks -> (+1000) win 17

Of course you need to assign probabilities to these outcomes and you really need the implied odds factoring RHOs ability to redouble with various hands but you only need to go from never beating it to beating it a little less than half the time even if RHO only redoubles when it's correct to do so.

Finally, in a Swiss match you might need better odds on the beat because match length and the VP table both favor frequency of gain over size of gain.

If we have a clear agreement that double asks partner to lead his weaker major I double. Pass otherwise.

It does seem very likely that without a heart lead 3NT will make easily, so doubling means we beat 3NT whenever it can be beaten. I think beating 3NT will be a lot more common than RHO having 6 or 7 diamonds and successfully redoubling.
That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.

I'd need to be at the table to decide, but I would definitely not auto-pull.

Note that the redouble is going to gain 5 IMPs in my scenario when right and cost 1 or 2 IMPs in my scenario when wrong. Therefore in theory RHO should almost always redouble, and we should almost always leave it in since the redouble doesn't give us much new information about RHOs hand. In my experience very few people would auto redouble on an odds basis, so I would consider pulling if I got a read.

My average of overtricks when i XX a lightner 3Nt is something close to 2 overtricks. So with a 5-5 is strongly suggest you to run.
