99. Should the partner of the player playing alone offer to take it from him after a lead has been made, or after he has himself passed, neither can play alone.
100. Should a player announce that he will play alone, and his partner play upon the first lead, the player loses his right to play the hand alone, and must play it with his partner, unless his adversaries elect that he play it alone.
101. Should a player announce that he will play alone, his partner must place his own cards on the table face downwards, and not again take them up. He shall have the right to gather and quit his partner's tricks, and his action is binding on his partner.
102. Should a player expose the face of any of his cards, his partner can score only two points, should he take every trick; but in case of a euchre the adversaries score four.
103. After the partner of the lone player has placed his hand on the table, either adversary may count the hand, to see if it contains more or less than five cards.
104. A player playing alone is liable to no penalty for simply exposing a card; but should he lead out of turn, the card is an exposed card, and can be called.
105. Should an adversary play out of turn to the lead of a lone hand, both opposing hands must be laid on the table, and can be called by the player playing alone.
ETIQUETTE OF EUCHRE.
106. The following rules belong to the established Etiquette of Euchre. They are not called “Laws,” as it is difficult, and in some cases impossible, to apply any penalty to their infraction, and the only remedy is to cease to play with the players who habitually disregard them.
107. Two packs of cards of different colors are invariably used at Clubs, and this should be adhered to if possible.
