     A. What card do you lead from dummy at the second trick?
     B. Which eight tricks do you expect to make?
 
 

Answers.

1. A. In dummy.
   B. The small Heart.
You cannot afford to touch trumps before clearing the stage for Heart ruffs in dummy.

2. A small Heart.  The Heart is a probable loser anyway.  But you cannot afford to ruff high, in case the Spades break 4-1.  Still less can you afford to ruff small and to be over-ruffed.

3. One trump (taken in declarer's hand), the Ace of Diamonds, and the Ace of Clubs.  The hand must be played on a cross ruff.  That is why dummy's deuce of trumps must be used at the first opportunity, leaving three trumps that cannot be over-ruffed.  The Ace of Clubs must be cashed quickly to avoid the danger of a ruff in the end game.  By then defenders may have had the opportunity to discard their Clubs.

4. A trump.  The catch is that there is no catch.  Declarer can count eleven winners, so long as a Club is not ruffed.  There is no need to ruff a Heart in dummy and every reason to draw trumps before allowing the defense to come in.

5. A. The King of Hearts; the Club and Diamond Aces; and seven trumps.
   B. The King and Ace of Hearts; the Club and Diamond Aces; and six trumps.

6. A. Ace and King of trumps.
   B. The three top Clubs.
If the Clubs break 4-2 - or worse - the eighth trick will have to be a Club ruff.  To prevent a Club over-ruff by a devender's losing trump, declarer draws two rounds of trump, leaving the defense with the best trump.  That is always a loser, and declarer does not mind if it is used to over-ruff a Club.

7. A. A Spade.
   B. The four Aces, the King of Diamonds, and three trumps.
The lead indicates that the Spade suit is divided 4-4-4-1, and dummy has enough entries to give declarer three ruffs, which is all he needs for his contract.

Without the partial dummy reversal, the contract may fail against a bad trump break, for declarer needs four winners out of his six trumps.
