OleBerg Posted January 18, 2009 Report Share Posted January 18, 2009 I would probably lead a spade at the table. (Not as big a fan as others of thrumph-leads vs grands, but here it seems safe.) But since you tell me there is a winning lead, I'll try a diamond, hoping to take out a vital entry from responders hand. (Responder may have to set up the club tricks by ruffing finesses, after seeing my partners singleton.) As dummy has a heart stopper, I cannot take out a vital entry in that suit. Edit: Answered this late at night, and thought I was leading through the strong spade hand. I'll take a shot at a lead in turn in another post.

whereagles Posted January 18, 2009 Report Share Posted January 18, 2009 I can't deduce much, except that if the normal spade lead doesn't break it, it's gotta be a red suit. Since diamonds is the obvious choice, I'll go with a heart. /sarcasm off :blink: Quote Link to comment Share on other sites More sharing options...
mtvesuvius Posted January 18, 2009 Report Share Posted January 18, 2009 A club cannot be right, because partner would have doubled with a void. A spade cannot be right becuase you said there is a winning lead, so I lead a red suit. Now... Which red suit? I lead one, and if it's wrong, I ask for an undo. Assuming they don't allow Modified Alcatraz Coup on leads... I think I'll try a diamond, for the reasons oleberg stated. Quote Link to comment Share on other sites More sharing options...
lamford Posted January 18, 2009 Report Share Posted January 18, 2009 I voted for a diamond, but I was trying to break up a double squeeze with declarer having a singleton diamond, and me guarding clubs and pard guarding hearts. But maybe a great partner didn't double in case they corrected to 7NT, so maybe he is void in clubs all along. Quote Link to comment Share on other sites More sharing options...
inquiry Posted January 19, 2009 Report Share Posted January 19, 2009 Not a ♠, might help declarer find partners Jxxx. Partner did not dbl 5♥ so he doesn't have ♥K behind the dummy's ♥ASo that leaves a ♣ or a ♦ as the correct lead. Opener has ♠AKQ, plus the ♥A. The dummy has the ♦A and the ♣A. Assuming he has 7♠, three side aces, and the two side kings, that is only 12 tricks. Only partner will be able to stop ♥s, we are probably the only one who can stop ♣, so the double threat suit looks like ♦s. The question is would a ♦ lead break up a double squeeze? Some double squeezes require two winners in the suit guarded by both opponents. If there is a simple squeeze on us, we can no knock out both entries to dummy (since there are two aces in dummy). So i will try a [ci] opening lead. I will lead the ♦T so as not to have partner play his ♦J and thus keep the potential for a double threat suit open, a small ♦ might make me alone responsible for the ♦ suit.

Finch Posted January 19, 2009 Author Report Share Posted January 19, 2009 Just because I've said there's a "winning lead" doesn't mean it's not a trump, if you see what I mean Quote Link to comment Share on other sites More sharing options...
gnasher Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) Just because I've said there's a "winning lead" doesn't mean it's not a trump, if you see what I mean Especially as a trump lead on this hand isn't particularly attractive. Can't the opponents have xx opposite AKQ10xx or even x opposite AKQ10xxx? Edited January 19, 2009 by gnasher Quote Link to comment Share on other sites More sharing options...
JLOL Posted January 19, 2009 Report Share Posted January 19, 2009 Based on the title I would guess a club is the winning lead, with RHO and partner both having a stiff this kills the club, and LHO has no entry (partner has the DA, LHO has the king). In real life I would lead a diamond, RHO has no control and LHO has the control, maybe we can cash 2 diamonds. I would also underlead my DA on this auction, so maybe they misguess (good if you have my image?!). Quote Link to comment Share on other sites More sharing options...

Suits seem to be breaking badly for declarer, he may depend on ruffs for tricks. Hence I lead a trump. As Lamford & Inquiry wrote, a ♦ may be necessary to break up the double-squeze, for example, if the layout is like that on the left.Incidentally, what lead would a Lightner double normally ask you to choose? IMO You should agree partnership priorities. for exampe...Unusual lead - common sense supervenes.Not trumpsNot a suit that partner could have eariler doubled safely for athe lead.Not the suit that partner earlier doubled, ostensibly for athe lead. Not the suit bid by our partnership.Except that if each of us has bid a suit, then lead your own suit.Often dummy's first bid side-suit.Failing that, declarer's side suit.Without any other indication lead a ♦. The old advert assured us that A double diamond works wonders[/hv] Quote Link to comment Share on other sites More sharing options...
Hanoi5 Posted January 19, 2009 Report Share Posted January 19, 2009 I led a small club. I expect dummy to have the diamond ace and even though I first thought of leading a diamond I don't think the opponents are bad players, 'cause it wasn't stated in the question.

peachy Posted January 19, 2009 Report Share Posted January 19, 2009 It isn't club because no Lightner, it isn't trump because you posted this as a problem and that would be a normal lead when they have solid trumps and opening leader has some protectable values. I'm normally never leading from xxx, pretty much regardless of auction so I'm picking a diamond. At least it takes away diamond ace from dummy (unless for some odd reason partner has the ace...)

mikeh Posted January 19, 2009 Report Share Posted January 19, 2009 I like the idea of the diamond lead to break up a squeeze. Neither major appeals.. spades at best may give up a tempo and at worst pick of Jxxx. Hearts may find partner with values, but in that case, dummy will hold AK of diamonds, and most layouts make a squeeze unavoidable.. or declarer with xxx in diamonds, ruffs one in dummy. Clubs... well, we need partner to hold some red cards, else opener has 13 top tricks, so he might tend to risk a double here if he were void in clubs... this is not a solid inference, but it is enough to make me choose to play for the squeeze-avoidance lead.

Phil Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) The question is would a ♦ lead break up a double squeeze? Some double squeezes require two winners in the suit guarded by both opponents. If there is a simple squeeze on us, we can no knock out both entries to dummy (since there are two aces in dummy). I agree. If dummy had ♦Axx and declarer has ♦Kx, a diamond lead accomplishes nothing. But ♦Ax in dummy and ♦Kxx and a diamond looks good in many normal double squeeze variations. If declarer has A or K, J, x of diamonds, I think we are always squoze in the minors, assuming declarer reads the position in the endgame.

OleBerg Posted January 20, 2009 Report Share Posted January 20, 2009 I go for the ♦10. A diamond to break up a squeeze, and the ten to allow partner to retain his guard (as someone else stated). Quote Link to comment Share on other sites More sharing options...
