After dropping a piece it must be able to make a legal move. This applies to Pawns, Knights or Lances. They may not be dropped onto a square from which they will never be able to move. Attacking the King by dropping a Pawn on the square in front of him is not allowed if the King cannot prevent being captured on the following move. In that case the players may decide to count their pieces where the King does not count, the Rook and Bishop count as 5 points, and all other pieces as one point.
Promotion is disregarded.
If a player has less, he loses the game. Of course, a player can refuse to count pieces when he still has mating chances or chances to gain material which would affect the outcome of the counting. It has been generally accepted that in such a case the game ends and the pieces are counted after one player has managed to get all his pieces protected in the promotion zone.
