When a hand contains no re-entry card, the successful play of the long suit may depend on a refusal to win the first trick; at times both the first and second tricks in the suit must be passed.
When you wish to make a long suit in a hand containing no re-entry card, do not play the commanding card of the suit until you are reasonably sure that the remainder of the cards will fall. Use care not to exhaust the shorter of the two hands before the suit is established.
The situation is more clearly shown by the following examples:
 |  |  |  |  |  |
 | |||||
 |  | ||||
The dealer should refuse to win the first round of the suit. With no card of re-entry, should he lead the ace and king, the command would be left with the adversaries and the suit would not be made.
|  | | |  |
| ||||
| | | ||
The dealer must allow the adversaries to win the first and second tricks; otherwise the suit cannot be made.
| | | | |
| ||||
 |  | | ||
The dealer should lead the queen toward the ace, but should the second in hand adversary cover with the king the dealer must pass the trick; otherwise the third round will be blocked by the nine or ten.
