removing it from the board. A ranging piece must stop where it captures, and cannot bypass a piece that is in its way. If a friendly piece intervenes, the moving piece is limited to a distance that stops short of the intervening piece; if the friendly piece is adjacent, it cannot move in that direction at all.
1686:
In cases where the above notation would be ambiguous, the designation of the start square is added after the designation for the piece in order to make clear which piece is meant. For example, if Black has two humpbacks (one was captured and dropped) which can be moved to the square e3, and these are

This variant invented by David
Paulowich in 2005 uses a 7x7 board and includes a new extra piece, the Pacific Northern Right Whale (A). It moves as a minor Gray Whale in that instead of sliding, it moves only one square, but also directly forwards or diagonally backwards—in other words, just like a

Games between players of disparate strength are often played with handicaps. In a handicap game, one or more of White's pieces is removed before the start of play, and White plays the first move of the game. Note that the pieces removed at the beginning play no further part in the game—they are not
1521:
When a player makes a move such that the opponent's white whale could be captured on the following move, the move is said to give check to the white whale; the white whale is said to be in check. If a player's white whale is in check and no legal move by that player will get the white whale out of

Each piece has its initial written on its face. On the reverse side of the porpoise is another letter (K for 'killer whale'), often in a different color (commonly red instead of black); this reverse side is turned up to indicate that the piece has been promoted during play. The pieces of the two

Captured pieces are truly captured in whale shogi. They are retained "in hand", and can be brought back into play under the capturing player's control. On any turn, instead of moving a piece across the board, a player can take a piece he has previously captured and place it on any empty square,
445:
The grey whale and killer whale can move any number of empty squares along a straight line, limited only by the edge of the board. The dolphin can, too, but only when on the back rank; it is a step mover elsewhere. If an opposing piece intervenes, it may be captured by moving to that square and

The method used in
English-language texts to express shogi moves was established by George Hodges in 1976. It is derived from the algebraic notation used for chess, but differs in several respects. This notation is modified for use in whale shogi in the letters used to name the pieces.
390:
That is, if a piece moves to a square occupied by an opposing piece, the opposing piece is displaced and removed from the board. A piece cannot move to a square occupied by a friendly piece (meaning another piece controlled by the moving player).
1561:
Games which are no contest are usually counted as draws in amateur tournaments, but if a professional-style tournament is to be played the rules may require the game to be replayed with colors reversed (possibly with reduced time limits).
365:
The players alternate turns, with Black moving first. (The traditional terms 'Black' and 'White' are used to differentiate the sides during discussion of the game, but are not literally descriptive.) A move consists of
421:
Some pieces move only one square at a time. (If a friendly piece occupies an adjacent square, the moving piece may not move in that direction; if an opposing piece is there, it may be displaced and captured.)
1509:
A dolphin cannot be dropped into the same file (vertical column) as two other dolphins controlled by the same player. For this reason, one may sacrifice a dolphin in order to gain flexibility for drops.
1512:
A dolphin cannot be dropped if the opponent would have no way to prevent his white whale being captured on the next move. In other words, a dolphin cannot be dropped to give immediate mate.
1571:
available for drops. The imbalance created by this method of handicapping is not as strong as it is in chess, because material advantage is not as powerful in whale shogi as in chess.
1558:. Recall, however, the prohibition against perpetual check. For two positions to be considered the same, the pieces in hand must be the same, as well as the position on the board.
1541:
A player who captures the opponent's white whale wins the game. In practice this rarely happens, as a player will resign when checkmated, as otherwise when loss is inevitable.
