If any player lead out of turn and the other three follow him, the trick is complete and the error cannot be rectified; but if only the second, or second and third, play to the false lead, their cards may be taken back; there is no penalty against anyone except the original offender, who, if he be one of the dealer's adversaries, may be penalised as provided above.
In no case can a player be compelled to play a card which would oblige him to revoke.
The call of an exposed card may be repeated at every trick until such card has been played.
If a player called on to lead a suit have none of it, the penalty is paid.
CARDS PLAYED IN ERROR
Should the third hand not have played and the fourth play before his partner, the latter (not being dummy or dealer) may be called upon to play his highest or lowest card of the suit played, or to win or lose the trick.
