21.—If one player play with more than nine cards, and the other with less than nine, the deal stands good. The player with more than nine cards is rubiconed (as provided in Law 17), and neither player scores the last trick.
22.—If a faced card be found in the stock after the play of the hand has begun, it must be turned
face downward, without altering its place in the stock.
23.—A card led in turn may not be taken up after it has been played to. A card played to a trick may not be taken up after the trick has been turned, or after another card has been drawn from the stock; but if two or more cards be played together, all but one may be taken up; and cards accidentally dropped may be taken up.
24.—A card led out of turn must be taken up, unless it has been played to. After it has been played to, it is too late to rectify the error.
25.—A player who wins a trick containing a brisque should at once take up all the played cards on the table, and turn them face downward near himself. If he fail to do so, his adversary is entitled, as soon as he has won a trick, to take up all the played cards on the table. Tricks turned may not be looked at (except as provided in Law 27).
26.—The stock may be counted, face downwards, at any time during the play. A player counting the stock should be careful not to disturb the order of the cards.
27.—A player may not count the brisques in his tricks so long as more than twelve cards remain in the stock.
Drawing.
28.—If the winner of a trick see two cards when drawing from the stock, he must show the top card to his adversary.
