Hello,
West leads 10 C, A from dummy, 8 from East, 3 from South
K and A trump, East gives 5 and 6 of trump, West gives 4 of trump first and discards 2 of spades after.
How to realize the contract?

Use the hand diagram editor (the spade symbol on the far end of the row of controls with the smiley face when you create/edit a post) to display a hand. It is very easy to use.

Now let me look at the resulting hand diagram in order to answer your question

edit: It looks like we have 13 tricks if spades are 4-3. So we need to consider the situation where they are not. My first instinct is to create a pointy suit squeeze like

♠3
♦Ax

facing

♠-
♥x
♦Qx

When the heart is played you can squeeze West if he holds both the long spade and the Kx diamonds. However there might be better lines which I'll leave to those who can see them

Thanks,

I'll try diagram option in the future and check your squeezing solution.

Regards.

Ahydra's squeeze only works if LHO has the spades and ♦K, because dummy has to discard before East does.

An improvement is to cash ♦A and then run all the trumps, coming down to ♠AKQJx opposite ♠x ♦Qx ♣xx. If either player has the spade guard and ♦K he has been squeezed.

Thanks Andy Bowles;
1.Suppose that at the beginning West has ♠ xxxx/♥ x/♦ Kxxxxx/ ♣ xx and East ♠ xxx/ ♥ xxxx/ ♦ x/ ♣ KQJxx. In this case I don't see how ♦ K is squeezed.
2.As hypothese K and A of trump are already played at the beginning,how after to cash ♦A you came to the hand and run all trumps?

I missed anything?

Thanks again.

Everyone is sleeping.

Firstly, you should not cash any trumps before planning the hand. Andy is suggesting cashing the diamond ace before playing any trumps. Now you squeeze West if he has five spades and the ♦K. Also, if by any chance East has a 5116 shape, he would also be squeezed.

However, if East is an honest sort of fellow who would not overcall 2♣ without the ♦K, you can go for a trump squeeze. Cash all the hearts but one throwing two diamonds and a spade from table. Then run the spades. When you play the last one, this is the position (West immaterial):

♠A
♥-
♦A
♣75

..........♠-
..........♥-
..........♦K8
..........♣KQ

♠-
♥3
♦Q76
♣-

Should you play this line? Against a solid East, yes. Which is why I like the ultra-modern trend away from weak jump overcalls involving range-merging within simple overcalls. Against the Italians (or any decent opponents), South should go for the straightforward Vienna coup line. I mean, my line gives up on spades 4-3, but punters will be motioning for you to claim once trumps break when that is the case.

Great PhilKing.
As usual:)

In this case, with Andy's line, you will win the 5th spade even though there is no squeeze: Andy's line doesn't give up on the possibility that the spades just break. Phil's line doesn't work with those cards - he reckoned that E would not overcall on those cards but rather could be relied upon to hold the DK. Which line you choose depends upon your judgment of your opponents, as to whether they are the kind make that overcall a strong 1C on any old rubbish.

It's not quite as simple as that. I am making the vast majority of the time spades are 4-3 by not doing anything too fiendish, and West is still squeezed on normal play when he has five spades and the diamond king. It's only when we discover that West has shortage in both hearts and clubs that I am even tempted to go for the trump squeeze, since the chances of spades breaking are now very low indeed (East would have to be 3406 and not have doubled the slam).

As the play develops I am cold as long as I can guess who has the diamond king, but I do not have to make a fatal discard until trick six. As you suggest, I need a pretty sick read not to just try and squeeze West.

I think the fatal discard is actually trick earlier.
Spades are bound to be 6-1 making lefty 6-4 or 6-5 shape so I don't think you'd ever dare risk the trump squeeze.
