2. The first player is bound to play in the suit he names; for instance,
if he should say hearts, and play clubs, or any other suit, he is
obliged, if his adversary insist on it, to take up the card he has
played, and to play in the declared suit.
3. If the adversary deem the card played more advantageous to his own
hand than the declared suit, he plays to it, and the card once covered
cannot be recalled in order to play a different suit.
4. He who plays before his turn is only obliged to take up his card
again, if it have not been played to; but if it be covered, the trick is
good. In this case, as in the preceding one, both players having been in
fault, one for having played and the other for having allowed him to
play out of turn, no penalty is incurred.
