1. He who turns up a king gains and marks one point: he who holds the
king of the suit turned up, gains and marks one point.
2. The king must be declared before it is played, by the holder of it
saying, I hold the king: it may also be declared after it has been
played; but, in that case, it must be the leading card, and not have
been covered by the adversary’s card; for if covered before declared,
the point cannot be marked.
3. This rule applies only to the elder hand; the second player must
always declare the king before he plays it; but it is his interest not
to declare it till after his adversary has played his first card.
4. The suit of the turn up card, or trump, is superior to all the other
suits.
