_=IRREGULARITIES IN DOUBLING.=_ If the pone doubles before his partner has asked him “Shall I play?” the maker of the trump shall say whether or not the double shall stand. If he allows it to stand it may be redoubled. Should a player redouble out of turn, the one whom he redoubles shall have the right to say whether or not the redouble shall stand. Any consultation between partners as to doubling or redoubling will entitle their adversaries to insist on a new deal. If the eldest hand leads without asking his partner’s permission to play, the pone cannot double without the consent of the maker of the trump. Should the pone ask the eldest hand, “Shall I play?” that does not deprive the eldest hand of the right to double. _=METHOD OF PLAYING.=_ The trump suit and the value of the tricks settled, the player on the dealer’s left begins by leading any card he pleases. After he has played, the second player, Y, lays his hand face up on the table, and takes no further part in the play beyond availing himself of the privilege of asking his partner if he has none of a suit to which he renounces.

One of these is _=Castling=_. If there are no pieces between the King and the Rook, and neither piece has been moved, the King may be moved two squares toward the Rook, and at the same time the Rook may be brought round to the other side of the King. The movement must be made with both hands, each manipulating a piece. In the position shown in Diagram No. 6, for instance, the King could castle on either side, with the King’s Rook, or with the Queen’s Rook:-- [Illustration: _No. 6._ +---+---+---+---+---+---+---+---+ | ♜ | | | | ♚ | | | ♜ | +---+---+---+---+---+---+---+---+ | ♟ | ♟ | ♟ | | ♛ | ♟ | ♟ | ♟ | +---+---+---+---+---+---+---+---+ | | | ♞ | ♟ | ♝ | ♞ | | | +---+---+---+---+---+---+---+---+ | | | ♝ | | ♟ | | | | +---+---+---+---+---+---+---+---+ | | | ♗ | | ♙ | | | | +---+---+---+---+---+---+---+---+ | | | ♘ | ♙ | ♗ | ♘ | | | +---+---+---+---+---+---+---+---+ | ♙ | ♙ | ♙ | | ♕ | ♙ | ♙ | ♙ | +---+---+---+---+---+---+---+---+ | ♖ | | | | ♔ | | | ♖ | +---+---+---+---+---+---+---+---+ ] If an adverse piece commands the square that would be passed over by the King in castling, the move is not allowed; because a King must not move into check, nor cross a square that is checked by an adverse piece nor castle out of check.
