17.--If a player play with more than nine cards he is rubiconed; but the
amount to be added to his adversary's score is not to exceed nine hundred,
exclusive of the thirteen hundred for a rubicon game.
18.--If both players play with more than nine cards, the game is null and
void.
19.--If a player play with less than nine cards, the error cannot be
rectified. He is liable to no penalty; his adversary wins the last trick.
20.--If both players play with less than nine cards, the deal stands good,
and the winner of the last trick scores it.
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 {25} 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.
