If you have to lose a trick in a suit, it is normally best to lose the first round. It’s a question of entries.
Exercise: Declaring notrumps, how can you enjoy dummy’s long cards (dummy has no other high cards)?
(A) Dummy (entryless)
♥ AK752
------
Declarer
♥ 4 3
Duck the first round, then lead over to ♥ AK hoping for a 3-3 split.
(B) Dummy (entryless)
♣ AQ652
------
Declarer
♣ 4 3
Duck the first round, then lead ♣ 4 to ♣ Q and, if the finesse is successful, cash ♣ A. You will score four tricks if the suit splits 3-3 with ♣ K sitting in front of ♣ AQ.
(C) Dummy (entryless)
♦ A8652
------
Declarer
♦ 743
You must duck the first two rounds hoping for a 3-2 split, then lead over to ♦ A and the two long cards.
(D) Dummy (entryless)
♠ AKQ72
------
Declarer
♠ 6 3
If you need all five spade tricks, you must lead over to ♠ AKQ hoping for a 3-3 split. If you need just four tricks, however, you can afford to lose one. That one must be the first round, so that you have a second card to lead over to ♠ AKQ and, now in dummy, to enjoy ♠ 7.

Lead: ♦ Q |
Don’t think of ducking techniques as only for notrumps – take our deal. Declarer – in 4 ♥ – won ♦ Q lead with ♦ A and sought to set up dummy’s clubs, thereby avoiding the need for a successful spade finesse. At trick two he led a club and, to save a dummy entry (thereby making ♣ A into a working entry), ducked a club (key play).
West won ♣ 10, led over to East’s ♦ K and East switched to ♠ J. Declarer tried ♠ Q but West won ♠ K and returned ♠ 8 (if he had switched to a trump, declarer would have had to win in hand to preserve ♥ AQ entries).
Declarer won ♠ A, cashed ♥ K, crossed to ♣ A, ruffed ♣ 6 with ♥ 10 (West discarding), crossed to ♥ Q and ruffed ♣ 8 with ♥ J. He led over to ♥ A and, with a flourish, cashed ♣ 9 discarding ♠ 4. 10 tricks and game made.
