You're sitting west and the auction went (all vulnerable):
2 - pass - pass - 4
pass - 5 - pass - 6
all pass

You lead K and see the following:
Scoring: IMP


Declarer plays low and you hold the trick (both declarer and partner follow suit). What's your plan to defeat this contract?

You must know the rules well - so that you may break them wisely!

Can declarer be trusted or is he just distracted? If he can be trusted, the play to trick 1 is a count reduction for a squeeze.

Play a diamond to break communications.

it is too difficult, I was in doubt if would mess comunications or give a free finese, nothing to do with the real answer.

It really doesn't matter much, as long as we don't play a . If pard has the J, there's nothing to break up, and if declarer has it, he has 12 tricks if he plays for the sqz.

Except that with the hand I gave, he will most likely take the finesse. (So I agree with not playing a .)

suppose declarer has the hand suggested: x, AKQxxxx,KJx,Ax

this will be the end position:



declarer leads his last h. we must keep Kx in s so must come down to 2 d or 1d and 1 c. dec throws his s T from dummy. p must keep 3 d and 1 c.
dec now leads a d to dummy and plays the A of s. p must now throw his c K or come down to 2d as well.


if dec is capable of executing this compound showup-squeeze we better lead a d now, if that gives a free finesse so be it. if we believe dec would not find the squeeze we might try something else but the way he is playing this would be futile.

so lead a d honor (else we might get squeezed by extracting ps d guard) and presto!

Hi,

just one question, why should declarer
play the weak 2 opener for KQJxxx and
add. honors?
We are red, ok, but usually a suit like
KQJxxx is sufficient enough, and the
vulnerability is equal.
And if I played such sound weak 2s, why
cant I have the 7 carder, declarer did not know
that I only have a 6 carder as he ducked the Ace.

I would play a trump, because this wont blow
a trick, if I get squeezed so be it.

With kind regards
Marlowe

PS: Maybe the squeeze works also if partner
holds both Quuens, but they may also split,
so in effect, I dont think ducking the Ace is the
percentage action at all, but declarer play is
certainly not one of my strengths.
the play .
With kind regards

That hand is what I was thinking about more or less, maybe without the Jack, but took a look at DF and it took me 5 minutes to realice why we had so few chances to defeat the contract. Hope you will be surprised as well

this is the endposition, dec not knowing who has the Q of d!

dec lead his last h. you must throw a d or the Q of c or unguard s. if you throw a s disaster strucks, if the c Q, p is squeezed betqeen his d guard and his c guard soon. so you discard a d.




also there are several layouts where there will be no ambiguity at all (if dec lacks the d J for instance) and he msut play for the drop if the c royals have not appeared.

it is not foolproof but the squeeze is much better than a simple finesse of the J of d so a good dec will play for that and succeed. therefore you must defend against that!

if -as you suggested - dec plays p for the honors he is sure to play for the drop as he thinks p has been squeezed out of d length by keeping c honors. any d finesse would have no chance at all then.

Declarer's hand was a lot worse than you guys expected:


I'll let you figure out how to defeat the contract :P

Yeah, I thought about this more, we do need to shift to a middle diamond. I believe a compound operates if we don't attack diamonds.

You have the same idea I had, but sadly that is not the answer, try again :).
