Enquire within upon everything

xiii. Before he plays, a player may require his partner to "draw his card," or he may have each card in the trick claimed before the trick be turned. xiv. When a player does not follow suit his partner is allowed to ask him whether he has any card of the suit led. xv. The penalty for a revoke--either by wrongfully trumping the suit led, or by playing a card of another suit--is the loss of three tricks; but no revoke can be claimed till the cards are abandoned, and the trick turned. [Revokes forfeit three tricks from the hand or score: or opponents may add three to their score; partner may ask and correct a trick if not turned; the revoking side cannot score out in that deal.] xvi. No revoke can be claimed after the tricks are gathered up, or after the cards are cut for the next deal. [The wilful mixing up of the cards in such case loses the game.] xvii. The proof of a revoke lies with the claimants, who may examine each trick on the completion of the round. xviii. If a revoke occur on both sides, there must be a new deal. xix. Honours cannot be counted unless they are claimed previous to the next deal. [No omission to score honours can be rectified after the cards are packed; but an overscore, if proved, must be deducted.] xx. Honours can only be called at eight points (in Long Whist), and at nine they do not count.
