Are you getting these out of books?

 

They all look really familiar.

From my bridge course notes

[Phil]

Your teacher must be George Coffin or Fred Karpin then.

[patroclo]

or maybe Carneade

If you want a spectacular example from real bridge:

 

[hv=pc=n&s=sakq98753hkq52dc5&n=s6hada6432cak8432]133|200[/hv]

 

We bid 2♣-3♣-4♠-7N

 

This is trivial unless they lead a spade, in which case you have to get rid of the A♥ to cash the KQ.

This is neat, thanks.

[Antraxxx]

That was cool nige1. Is the answer (to the old one) that west has

 

♠K8

♥T98

♦J965

♣T987

?

Well done, Antraxxx :) :) :)

But that was not my intended solution :(

Please try the modified version above which should eliminate that solution.

[Antraxxx]

That seems similar, except now you need east to have

 

♠Q

♥T98

♦J9865

♣T987

right?

Almost :)

but East is discarding after dummy :)

(but my second favourite Bridge World composition).

[Antraxxx]

I don't see the problem.

You pitch two high hearts, east pitches two low diamonds. You then pitch two low clubs, east pitches a diamond and:

a] a diamond: cash two high hearts and discard AK of diamonds, then run your diamonds.

b] a club: cross to dummy in diamonds and cash all the good clubs

c] a heart: cash three heart tricks discarding clubs, cross in diamonds and cash out.

 

What'd I miss?

You worried me :( but if RHO abandons diamonds, I think you're left in hand, with a losing heart and no dummy entry. Your reconstruction doesn't uniquely determine the pips in opponents' hands: you've missed something trivial that you'll find quickly :)

 

[Antraxxx]

I'm afraid I still don't get it.

 

I overtake ♠K with ♠A when the ♠Q drops on my right. I play ♠JT98 and discard ♥AK and ♣32.

Now in my hand I have:

♥QJ7

♦QT432

And in dummy I have:

♦AK

♣AQJ654

RHO had to make 4 discards on my spades. If any of them was a heart, I can take my ♥QJ7, throwing off three clubs, then ♦AK and ♣AQJ.

If any of the discards was a club, I now play ♦AK and then clubs from the top.

Otherwise, RHO held on to 3 hearts and four clubs, so he has only the ♦J. I cash ♥QJ and discard ♦AK. I then run diamonds from the top.

Suppose RHO abandons diamonds. Your line is to cash ♥AK discarding ♦AK. And then run your diamonds. At trick thirteen, you are left with ♥7, which loses to RHO's ♥T -- one off in 7NT :(

 

[Antraxxx]

Oh, right! So

Move ♦J to be singleton in west's hand, and start by discarding ♦AK and not the ♥AK (and still 2 clubs).

(Delayed jettison repeating squeeze)

Antraxxx and I are the only two still involved in this discussion, so I shall dot the i's and cross the t's:

You, South, are declarer in 7NT. West leads ♠7. Antraxxx correctly surmised that you need the cards to lie precisely as in the diagram. You win in hand with ♠A and cash spades, discarding a club and both red kings. The penultimate spade triple-squeezes RHO. If he discards a club, then dummy is high, so he must abandon a red suit, say hearts. On the last spade, you discard the ♥A (the suit that RHO abandoned). You cash ♥QJ7, discarding two clubs. The penultimate heart squeezes RHO again, in a similar way, for the remaining tricks.[/hv]
