none of the suit led, may play any card he holds.
(b) A trick consists of four cards played in succession, beginning with a lead.
(c) A trick containing one trump-card or more,
is won by the player who plays the highest trumpcard. A trick containing no trump-card, is won by
the player who plays the highest card of the suit led.
(d) Declarer gathers all tricks won by himself
or Dummy; either adversary may gather all tricks
won by his side. All tricks gathered by a side should
be kept together and so arranged that the number
thereof may be observed, and the identity of each
trick readily established. A trick gathered by the
wrong side may be claimed by the rightful owners
at any time prior to recording the score for the current hand.
(e) A quitted trick may be examined upon demand of any player whose side has not led or played
to the following trick.
(f) The winner of each trick leads to the next,
until the last trick is played.
THE MADE CONTRACT
36 (a) The Made Contract represents the
number of tricks won by Declarer after he has won
six tricks, up to and including the number of tricks
named in his contract. The first six tricks won by
Declarer constitute his book and have no scoring
value. If Declarer fails to win the contract, his side
scores nothing for tricks; but if he makes his contract, his side scores in their contract score, the
value, normal, doubled or redoubled, of the Made
Contract. For the Made Contract trick values see
