Hand1
Declaror is marked with the AKJ of spades and KC for his opening bid, so you need 2 club tricks. However if declaror has a doublton diamond he can set up the suit with a ruff and using dummies 3rd spade as the entry to the established diamond suit. However you have a counter. Force dummy to trump so declaror cannot draw trump ending in dummy. Lead a third heart.
By the way, declarer has a third heart. If that Jack was a true card, partner would have started with 8654 and should play the 5 the second time,( current count )
One way ti kill a long suit in dummy that has to be set up with a ruf, the only side suit entry being the trump suit, is to force dummy to trump leaving one defender with more trumps than dummy.
Hand 2
Switch to JD !! You can see the clubs are soon to be set up and declarer will discard diamondson clubs so clearly it must be right to switch to diamonds, but why the Jack?
If declarer has the A and partner the K, it doesnt matter which diamond you lead. If partner has AD and declarer the K10. it also doesnt matter which diamond you lead. In both cases you are only going to make 1 trick.
The critical holding in declarer's hand is K8x. In that case it is neccesary to switch to the Jack, and hope that declarer thinks you have J10. If he does, he will play low and dummy's Q will win. When you get in with the AC and play a second D, partner now has A10 hovering over declarer's K and you will get 2 diamond tricks to defeat the contract.
THE Bottom Line
There are times when you need to make non standard leads from certain card combinations. These leads almost always take place later in the hand and are hard to classif. It helps if you know standard card combinations.
