Exempel på hur du använder ROOK i en mening

• It may move to any adjoining square; it may also perform, in tandem with the rook, a special move called castling.
• It can move any number of squares vertically, horizontally or , combining the powers of the rook and bishop.
• The rook may capture an enemy piece by moving to the square on which the enemy piece stands, removing it from play.
• When unobstructed, a rook attacks fourteen squares regardless of position, whereas a bishop attacks no more than thirteen (from one of four center squares) and sometimes as few as seven (from sides and corners).
• Castling is permitted only if neither the king nor the rook has previously moved; the squares between the king and the rook are vacant; and the king does not leave, cross over, or finish on a square attacked by an enemy piece.
• A knight fork of all four other major pieces, the king, queen, rook, and bishop, at the same time, is known as a quadruple fork, and if the pieces are arranged with 4-way rotational symmetry, it is also informally known as the German fork, due to the shape of the knight moves resembling a swastika, which Nazi Germany used as the central symbol of its flag.
• The rules of chaturanga seen in India today have enormous variation, but all involve four branches (angas) of the army: the horse (knight), the elephant (bishop), the chariot (rook) and the foot soldier (pawn), played on an 8×8 board.
• Both authors describe custodian and intervention capture, but only Samusah describes orthogonal movement of pieces as in the rook in chess.
• For instance, a white pawn captured on b4 is reborn on b2; a black knight captured on f6 is reborn on b8; a black rook captured on the same square is reborn on h8.
• Positions with zugzwang occur fairly often in chess endgames, especially in king and pawn endgames and elementary checkmates (such as a rook and king against a lone king).
• His likely primary motivation for the design was either the limitations of opening theory in this time or that he already foresaw the logic of chess playing out to the game being about the second player’s response to the King’s or queen’s pawn opening and he was not as concerned with avoiding structural weaknesses in the new game’s starting position created by a potential new piece standing on a given file, as with the archbishop between the knight and the rook leaving its own pawn unprotected.
• Byrne captures the queen, but Fischer gets copious material for it – a rook, two bishops, and a pawn.
• The setup is unknown, but can reasonably be assumed to have been the same as in modern shogi (minus the rook and bishop, and minus a gold general in the 8×8 case), but possibly the pawns started on the second rank rather than the third.
• However, any bishop or rook move must unguard one of the squares of d5, d6, d7 or d8, allowing White to mate on d5, d6 or d7 with the queen, and d8 with the knight.
• f3 (giving black a flight at f4), white plays his rook back to where it came from (a switchback) to take advantage of the newly opened fourth rank: 2.
• For example, in chess, assume a situation where the computer only searches the game tree to six plies and from the current position determines that the queen is lost in the sixth ply; and suppose there is a move in the search depth where it may sacrifice a rook, and the loss of the queen is pushed to the eighth ply.
• This interferes with black's rook and bishop, and whichever of those pieces takes the knight, it will interfere with the other—this is the Novotny idea at its most basic.
• However, the FEN castling availability encoding (KQkq) is inadequate for variants in which there are two rooks on the same side of the king on the back rank, as if only one rook were available for castling it would be ambiguous which rook it was without knowing their initial positions.
• The black king is not in check from the rook on c5, because it (the rook) is attacked by the black rook on g5, meaning it is paralysed.
• Rather than defending his own position, Black offers a counter-sacrifice to activate his a8 rook with tempo.
