Pd leads K, which is your power lead, asking for unblock or count in that order. Udca carding. No smith available. Expert pd.

T1- K-A-8-2
T2- A-3-T-J
T3- K-5-2-5
T4- 9-Q-7-4
T5- 4-3-3-6
T5- 3-6-Q-2
T6- 5-J-A and how would you go from here in defense and why ?

How about an ordinary small club? If declarer continues club from dummy, I will win the king and exit a spade. If he cashes dummy's diamond at any point I am pitching a small club. Declarer will get four diamonds, the heart ace, the club ace, and two spades. I will get three spades, the diamond queen, and the club king.. unless at some point declarer calls a heart from dummy in which case we should have no trouble scoring two hearts, a diamond, a club, and a spade.

It is superficially appealing to unblock the club king, but partner could easily have a hand like xxx KQJ9xx x JTx in which case he will be endplayed by three rounds of clubs and forced to give declarer a trick with the heart ten.

On this layout if you can unblock he can also cash the last diamond and then exit a heart. This type of thing can also happen if I unblock and partner has QJx in the club suit.

The only layouts where it is right to unblock are those where declarer has a second heart trick. Could partner have led from KJTxxx? In that case unblocking is necessary as they only need to establish one spade trick, and that cannot be prevented if you keep the club K, as you need to bare it on the last diamond.

Declarer would hardly have played that way with Qxxxx, nor should partner play the J from JTx.
In your layout declarer would not be so keen to unblock the T on the first diamond. This gives the show away that he does not have the Q.
After K dropping the J, declarer would try to establish clubs. Now unblocking the K on the A at trick 3, which is not so easy, would become necessary to beat the contract.

However, partner might hold xxx KQTxxx J QJx or xxx KQJxxx J QJx , where tossing the K gives away the contract now.

For me playing the J in this position denies the T or 9. But whatever partner has in clubs, how does it help to unblock the K assuming that partner has KJTxxx?
Why can I not discard a spade on the fifth diamond? "Unblocking" the K does not help, only allows declarer to establish clubs for an overtrick.
I see no layout where you have to get rid of the K now.
If partner has played a weird J from QJ9 or QJT, discard a spade on the fifth diamond, play low on the club from dummy and the K on the J.

Can you think of any layouts where it is necessary to unblock the K? All I could come up with was partner having QJT/QJ9C and KJT9xx hearts, so he needs two entries to establish the hearts and we must not give away a spade trick.

No.

Discard a spade on the fifth diamond, play low on the club and finally dump the K on the J.

Clarify afterwards with partner why he thinks it a clever idea to play the J from QJT or QJ9.

Awm nailed it this hand. Weldone bro!

Pd had

542
KQT9xx
J
JTx

And yes, Phil, that douchebag was me :(

I did not unblock the K, although i thought about it as Adam said it is tempting. I did, however, something worse than this. I discarded a spade on 5th . Which made it impossible to defeat now when declarer played 2nd club from dummy.

As Rainer points out i was too occupied with the line declarer choosed and the meaning of J, but i should have got this one right regardless.
