Unless of course it is partners bid suit, leading doubletons is common practice but I think an overrated and somewhat risky lead.
I am providing a quick talk on doubletons at the non sanctioned game today and wondering if there is some more wisdom I can gain from bbf'ers.

We have competitive and noncompetitive auctions, leading a doubleton and following suit with a doubton.

Leading a doubleton when partner has bid the suit. high - low or low - high
Blind leads, what may be preferable than a doubleton against a suit contract. (touching honors, trump lead, 4th best, singleton!)
Following suit with a doubleton, high - low or low - high

Too late to help with your talk but if you want to improve your understanding of leads, I strongly recommend the Bird and Anthias books on leads…one v notrump and the other v units. Be aware that, imo, they tend to slightly underestimate the impact of their double dummy analysis…hence, as one example, their results overstate, imo, the effectiveness of leading an unsupported ace, since when they do so they always make the right switch. At the table, partner will think you have the king (assuming ace from ace king) so he’ll give you the ‘wrong’ sighal and most human defenders will then not defend double dummy. Despite this issue, the books are, imo, extremely good.

Perhaps of (slightly) more use today: on some hands the lead is obvious…a singleton in partner’s suit v a suit contract, of the King from KQJ10x against a notrump contract, etc. but on many, many hands there will be two, three or even four plausible choices…many hands on which one is considering leading a doubleton would be in these categories.

On those hands, I doubt any sort of blanket rule would be valid. As with so much in this game, context matters. One needs to really think about the auction…try to deduce at least something about the other three hands. This can be easy…everyone has been bidding…or very difficult…say 1N P 3N P).

Then one has to decide whether we are going to try to set the contract or avoid giving up an overtrick or two. At imps, for example, one tends to make the lead that has the most potential for a set…here, a doubleton in an unbid suit..or a suit bid only once by dummy, may be best…one needs a couple of trump and ideally the auction suggests partner has some strength. You might also lead that at mps not so much to go plus but because it may be the safest lead or the best combination of safety with some hope of going plus.

There’s a reason that there have been books written on leads. I’d never tell any students that they should avoid leading doubletons against suit contracts….but I’d also avoid saying that they should always do so.

I appreciate that your audience likely won’t ‘get’ the subtleties so you may need to keep it simple. But if you do…I’d suggest at least prefacing your remarks with something to the effect that as they advance in the game they will come across hands where your general advice may not be correct.

The book makes a case, that doubleton leads are quite often a reasonable choice, since they tend to be passive leads.

Not too late, the game starts at 12:30

Yes, xx can be a reasonable, passive leads I think the subtleties, as Mike mentioned, are not well understood by newer players.
For some reason, doubletons are a favoured lead and I was asked to talk on this, I think lead vs. following suit, blind vs. suggested leads and a little
on alternatives will be enough today. These are very much kitchen bridge players with a handful of players excited, willing and able to learn there is more to the game.

I do always preface what I say with "this is just one of many, many approaches, decide with your partner which approach you prefer".
I will be sure to add, as you get more experienced, these methods will change. (and as methods change...)

I like doubleton leads -- they have more upside than leading from three or four small (both because a ruff is possible, and because they tend to give partner more clarity in my carding where we lead high from doubleton). Of course, singleton leads or leads from a sequence of three cards are better (but you often don't have these things in your hand). There are also auctions that call for a more aggressive lead (although the Bird-Anthias books back my feeling that a passive lead is usually better when the auction doesn't suggest anything in particular).

I don't claim it means anything, but I personally will not lead a (small) doubleton against a suit contract unless it is partner's suit or it's the only unbid suit. Likewise against notrump I guess.

This has at least the benefit that partner will not have to guess whether it's a singleton or a doubleton.

Well, if the auction suggests a trump lead, I lead a trump regardless the length. (But low from doubleton honor.)

[pescetom]

The partner that most influenced me in terms of play was firm that a doubleton lead was a last resort.
I slowly learned to rank it higher, as mikeh said on some hands it is even obvious.
In a talk to a club field I would provide a few examples and encourage discussion rather than try to list elusive truths.

Interesting thread. Am following

Thinking of unblocking partners suit and things like that

[jillybean]

A friend dropped off those 2 Bird Anthias books today.
After reading the first page of Winning Suit Contract Leads , I see I need to retract my comment about doubletons being passive leads.

[Huibertus]

Doubleton leads (aiming to receive a ruff) are not bad in itself, sometimes they work and are the only way to defeat a contract, sometimes they don't work but don't harm, and sometimes they give away tempo and the contract in the process. But that is the case for almost all types of leads.

The problem with doubleton leads was once explained to me by a bridge teacher who himself played in the (Dutch) national team; "If you want to receive your ruffs when you lead a singleton, don't lead doubletons".

And that makes perfect sense, i.e. when you lead a doubleton partner frequently will have to duck the ace in the suit you lead in order to ever be able to give you a ruff. That is NOT what you want him to do when you lead a singleton. And as it is often very hard to guess if the lead was a doubleton or a singleton (not always), partner will guess wrong at times when you frequent doubleton leads.

Now that doesn't mean you literally should never lead a doubleton, just keep it in mind when you have an alternative lead and in THAT case try to steer away from leading the doubleton.

One piece of advice from a book that I remember is "a doubleton lead can be effective when you have trump control". So Axx trumps gives you a second chance and makes it more attractive.

Hi,

my take is, that the DD lead is heart.
The auction makes no real case that an agressive lead is req., you have no idea,
how strong opener is, club does not develop a trick with a high degree of certainty,
so it is basically risky, with low chance of hitting it big.

The Ace of diamonds gives you a 2nd shot.
It is not about getting a ruff, it is about not blowing a trick.

Your diamond length is not exceptional, I think the unsupported Ace lead was either
short (Doubleton) or long 6+.

With kind regards
Marlowe

Nothing looks promising so, as is often the case, let’s try a process of elimination, understanding that this is imprecise and any resulting decision will turn out poorly much of the time.

Trump? They often have 9 trump on this auction and a trump lead can’t blow a trick if they do. Furthermore, if they have only 8, the ‘usual’ play with something like AJxxx opposite K10x will pick off partner’s Qxx anyway. Main immediate danger is partner has QJx and declarer AK10xx. He might well not double hook if we stay off the suit. Also make it A9xxx opposite Q10x and we might get two tricks from partner’s KJx unless we lead trump. But most of the time the spade lead will not cost directly. What it does do is give up a tempo. And that could be very costly.

Heart? Partner could well have values over there since we have a 5 count. Not only might we get a ruff but we may set up a trick or two in the suit while we have diamonds controlled. We might solve a guess in hearts but that will not be a common outcome. Seems to have more upside and less downside than a trump.

Diamond? If we lead the suit we are leading the ace. Underleads of aces against suit contracts, on opening lead, should be reserved for slams…and then only if the auction suggests rolling the dice. The Ace will almost never work well. We are giving up control of a suit…the opps don’t rate to need to set up diamonds but picture declarer with Kx(x) and dummy with say xxx.

The lead likely surrenders a tempo, may easily blow up the suit. Sure, we could cash two quick winners when partner has the king and declarer has somewhere to pitch a diamond loser, but that’s quite the parley. The odds don’t seem to favour this lead.

Club? I ‘learned’ a long time ago that Jxxx was perhaps the worst lead possible, absent something in the auction pointing to a need to lead the suit. Bird and Anthias have shown that it’s not always as bad as it used to be thought but it’s still not a great lead. It can blow the suit on a number of layouts, although some require a good guess by declarer.

It could set up a trick…picture KQx in partner’s hand or K10x sitting over Qxx. But even if that’s the case, there may be no rush. While I rank clubs as second choice, I think hearts offers a better combination of passivity and aggression. So I’d rank the options as hearts, clubs (very narrowly over trump), trump and, a distant last, diamonds
