Reproduction chess

In Reproduction Chess, all the rules of traditional chess apply, including the initial positioning of the pieces. The main difference between Reproduction Chess and traditional chess is the change in the rules and behavior of the Queen piece. During the game, the player can pass instead of making a move, this will cause the Queen to become pregnant. The player can complete the Queen's pregnancy in two ways:

  1. By placing a pawn on a square adjacent horizontally or vertically to the Queen ( from above, below, to the left or to the right of the Queen ).
    In this case, the player cannot move the Queen and complete the pregnancy at the same time. He must do it in a separate move.
  2. After making a Queen move, the player may place a pawn on the square left by the Queen during this move.

The Queen's pregnancy can only be completed when the player has fewer than eight of his pawns on the board !!!.

Pawn promotion
If the Queen, after becoming pregnant, places a pawn on the seventh or eighth row, this pawn can only be promoted to Prince.
The Prince moves like the King but only captures diagonally. In other cases, pawn promotion is as in traditional chess.

Pawn double step
A pawn can move two squares in its first move if it is placed on the first or second row.
In other cases, the pawn moves one square.

Restrictions for the Queen after she becomes pregnant - OPTIONAL RULE
Once pregnant, the Queen cannot capture enemy pieces.

Restrictions on the number of pregnancies – OPTIONAL RULE
Players can determine how many pregnancies the Queen can get during the game.

Reproduction Chess – another variant
In this variant of Reproduction Chess, the player can complete the Queen's pregnancy using only the second method described above.
