In case of a revoke on both sides, the deal is void.
In order to prevent revokes as far as possible, the rule should be stringently observed of calling a player's attention to the fact that he renounces upon or trumps a led suit. The general question is, "You have no spade, partner?" or whatever the suit may be to which he has not followed. These remarks do not apply to a misère, because in the case of that declaration an exposed card is as fatal as a revoke itself.
If one man proposes, and another man, not hearing or not noticing, also says, "I propose," the second declaration cannot be amended to an acceptance, but any other player may accept, or the original proposer may amend his call to anything better.
In the same way, a player may call one thing when he intends something else. If he correct himself instantly, it is courteous to let the change be made; but he cannot claim this indulgence.
What we have said about improper calls applies with increased strength to improper remarks or suggestions.
As a general rule, it may be said that any remark made conveying an unfair intimation to partners entitles the other side to throw up the cards and demand a fresh deal.
As at Whist, however, a player may ask for the cards on the table to be "placed" when it is his turn to play, just as he may ask to see the last trick, or to know what suit are trumps. This demand to
see the last trick holds good at all declarations except a misère.
A trick once turned in a misère must not be looked at or referred to; but in the other phases of the game, any player at the table, whether it is his turn to play or not, may ask to see the last trick, and must be shown it, but he can never see more than eight cards, and if there are no cards on the table he can only see the last trick. He can never see two tricks that have been turned.
Should the cards be improperly divided, the declaring hand or hands win the stakes if their own cards are correct, and any person or partnership with the incorrect number of cards must, whatever has happened, lose the stake, unless the error is discovered before the first call is announced.
