22.—If a king be turned up, the dealer is entitled to mark it at any time before the trump card of the next deal is turned up.
23.—If either player hold the king of trumps, he must announce it before playing his first card, or he loses the right to mark it. It is not sufficient to mark the king held in hand without announcing it.
24.—If the king be the card first led, it may be announced at any time prior to its being played to. If the king be the card first played by the dealer, he may announce it at any time before he plays again.
25.—If a player, not holding the king, announce it, and fail to declare his error before he has played a card, the adversary may correct the score, and has
the option of requiring the hands to be played over again, notwithstanding that he may have abandoned his hand. If the offender win the point he marks nothing; if he win the vole he marks only one; if he win the point when his adversary has played without proposing, or has refused the first proposal, he marks only one. But if the adversary himself hold the king, there is no penalty.
26.—If a player propose, he cannot retract; nor can he alter the number of cards asked for.[[22]]
27.—The dealer, having accepted or refused, cannot retract. The dealer, if required, must inform his adversary how many cards he has taken.
28.—Each player, before taking cards, must put his discard face downward on the table, apart from the stock, and from his adversary's discard. Cards once discarded must not be looked at.
29.—If the non-dealer take more cards than he has discarded, and mix any of them with his hand, the dealer may claim a fresh deal. If the dealer elect to play the hand, he draws the superfluous cards from the non-dealer's hand. Should the non-dealer have taken up any of the cards given him, the dealer is entitled to look at the cards he draws.
30.—If the non-dealer asks for less cards than he has discarded, the dealer counts as tricks all cards which cannot be played to.
