'I am not sure if this will clarify or confuse the issue, but here is a
summary from an old post of George Fernandez:'
*** *** *** *** *** ***
The last version of 'The rules of shogi' I have was written in 1993 by
Mr. K. Horiguchi 6 Dan[supplement to the January 1993 issue of Shogi
Sekai]. The 96 page booklet, written in japanese, is the official rule book
accepted by the Japanese Shogi Association.
The following definitions were given which apply here:
Checkmate:
A checkmate is a position in which a King is in check and there are no
legal moves to leave the check.
Illegal moves:
(1)A move is illegal to make a double pawn.
(2)A move is illegal to make a deadlocked piece.
(3)A move is illegal for a player if his King's square is attacked by an
opponent piece after the move.[to remain in check, to move into check
or to expose the king to check]
(4)A move is illegal to make a repetition check move [Mr. Horiguchi
wrote in an addendum the following clarification: '... In the event
of perpetual check, if one player player does it FOUR TIMES(three
times is permitted), he will lose his game'.
(5)A move is illegal to make a dropping check move by a pawn which leads
to a position in checkmate at once(dropped-pawn mate).
Legal moves:
A legal move for a player is a move to leave the check by moving pieces
on the board or by dropping if his king is in check. Otherwise, a legal
move by a piece on the board which can go[move] or a drop move, which is
not illegal.
Remark (condition of ending game):
1. The game is finished if the position is in a checkmate; The player to
move loses the game.
2. The game is finished if one player makes an illegal move; This player
loses the game.
3. The game is finished if one player has no legal moves; This player
loses the game[contrary to chess rules, where a stalemate is
considered a draw].
4. The game is finished if one player resigns; This player loses the
game.
In an effort to put this issue behind us, and move on, I'm sharing with you
a bizzare diagram from the 1993 rules book[page 93, digram #92].
***ENDQUOTE*** I [David Paulowich] am unable to format the diagram for this text message. It shows a stalemate loss for the lone White King. But Black to move also has no legal moves, even though he has a huge army and a Pawn in hand (dropping that Pawn would be mate).
