After a Three Spades opening from North, East-West reached
Six No-Trumps.  How should declarer play the Diamonds?

6. The contract and the East-West hands are as in #5,  But
this time South who opened the bidding with Three Spades.
How should declarer play the diamonds?

1A. No.
1B. In his own hand, three top Hearts and two top Clubs.  In dummy, one Spade and three top Diamonds.
The point of the hand is to create an entry to dummy's Diamonds by throwing the King of Spades on the Ace at the first trick.

2A. Yes.
2B. After the Ace of Clubs, declarer lays down the Ace and King of Spades, then the two top Diamonds, followed by the nine.  The object is to create an entry to dummy with the six of Diamonds.  Two entries are required - to drive out the Queen of Spades and then to reach the two good Spades.  The Clubs provide one entry.  The six of Diamonds will be the other.

3A. The Ace.
3B. North would not have led a small card from a suit headed by: KQJ; KQ10; QJ10; or KJ10.  Therefore, South must have two bare honors.  If North has five Hearts - which alone can worry declarer - South holds two bare honors, and the play of the Ace from dummy to the first trick will block the suit.

4A. The King.  Declarer cannot afford a HOLD-Up, for he may lose three clubs, as well as the Ace of Diamonds.
4C. The finesse against the Jack of Spades.  Declarer needs two entries to dummy - to drive out the Ace of Diamonds, and then to get at the suit after it has been established.  His only hope of reaching the table twice is to find North with the Jack of Spades.

5. The King first.  If North shows out, declarer can still catch South's J 10.  If North follows with the Jack or ten, the Ace is layed down to clarify the position.  There is no certain way of making all four Diamonds, because North may have a singleton x, which reveals nothing.  But declarer must realize from the bidding that North is likely to be short in Diamonds and may have a void or singleton.

6. The Ace first.  This time South is likely to be short in Diamonds, but declarer can still make four tricks in the suit if South has a singleton Jack or ten.  Nothing can be done against J 10 x x (x) in North's hand.
