Nyugyoku (入玉)
Regarding Nyugyoku (King’s entry into the opponent’s 3-line territory) in this tournament, a 27-point Nyugyoku Declaration Rule (27点入玉宣言法) is applied in accordance with FESA’s standard (Article 5.3)
For the purposes of finishing of the games, in which there is no realistic prospect of checkmate, a “27- point Declaration System” applies.
The declarer (the player who seeks to declare win), while having the turn to play, first announces his will to declare win before making his next move. And then, he stops the clock and suspends the game.
If the position at that point meets all the requirements listed below, the declarer wins the game.
1. Declarer’s King is in the declarer’s promotion zone;
2. Declarer has at least 28 points if Sente, 27 points if Gote. For the purposes of the counting:
*King (王将): 0 pt, Rook (飛車) and Bishop (角行): 5 pt, the other pieces: 1 pt regardless of promoted or unpromoted
3. The pieces to be counted are only those in the opponent’s camp, and his hand pieces.
4. Declarer has at least 10 pieces in the opponent’s camp other than his King.
5. Declarer has his thinking time or Byo-yomi left.
6. Declarer’s King is not in check.
If any of the above requirements is not met, the declarer loses the game.
