Defensive problem


Free

Recommended Posts

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:

[hv=d=w&v=b&n=sat854hjt5da54cj9&w=skqj762h6dqt6cqt4]266|200|Scoring: IMP[/hv]

 

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

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:

 

 

 

[hv=n=sathdaxcj&s=shxdkjxcx]133|200|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.[/hv]

 

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 .

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.

Maybe he has x AKQxxxx KJx Ax :P

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.[hv=n=sathdaxcj&w=sqjhdxxcq&e=shdqxxckx&s=shxdkjxcx]399|300|[/hv]

 

[hv=n=sathdaxcj&w=sqjhdxxcq&e=shdqxxckx&s=shxdkjxcx]399|300|[/hv]

 

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.

i just wanted to show that dec might play for a compound squeeze if he had the hand suggested (with the J of d) if we led a c for instance on the second trick. his d however are (very) slightly too weak...

 

with the actual hand he surely would play for a compound as there is no other chance. however his d are too weak to make them a threat in a guard compound squeeze as i thought, because p will not be threatened by an eventual d finesse against his J (if dec had at least K9x that would work!), so my d are not needed to guard against that!

 

in our example the only way for dec to win is to play for a compound with c the menace in hand and the A an entry. to destroy this squeeze we must attack this entry by switching to a c ! the Q would establish a double squeeze with d the double menace and the c J a menace against p. therefore....

 

lead the T or the low c!

 

however as suggested, with the 9 of d instead of the 8, dec would survive after that silly opening lead of the K of s! there would be no way to beat the contract anymore after declarer made the routine play of ducking the A of s on the 1st trick!! lol
