Simplified Makpong

Makpong is a variant of Makruk where the King may not move out of check, except to capture its singular attacker.

The King may capture its attacker if in range. In the case of a double check, the game is automatically lost for the (now) checkmated side.

Makpong is designed to reduce draws.

Over the board it is used as tie breaker in Makruk single elimination tournaments.

This variant of Makpong simplifies away the unituitive counting rules of Makruk for a 50 move rule and 3-fold repetition.

Setup

The opening setup is very similar to that of orthodox chess, with the following differences: the positions of white king and queen are reversed, and all pawns are on the third and sixth row. So, the setup is as follows:

White: King d1; Queen e1; Rook a1, h1; Knight b1, g1; Bishop c1, f1; Pawn a3, b3, c3, d3, e3, f3, g3, h3.

Black: King d8; Queen e8; Rook a8, h8; Knight b8, g8; Bishop c8, f8; Pawn a6, b6, c6, d6, e6, f6, g6, h6

 

.

Pieces

The king, rook, and knight move as in orthodox chess, except that castling does not exist in this game.

The queen moves one square diagonally. (Ferz)

The bishop moves one square straight forward or one square diagonally. (Silver General in Shogi)

The pawn moves as a normal pawn, but may not make a double step on its first move. When it reaches the sixth row (third row for black), it promotes to a queen. (Ferz)

Rules

Object of the game is to mate the opponents king. Stalemate is a draw.

The King may not move out of check, except to capture its singular attacker.

Other pieces are free to move if the king is in check, provided it's legal to do so. (Either by blocking the attacking piece, or capturing it)

50 move rule and 3-fold draws are in effect. There's no castling, no pawn double step, no en passant. Pawns promote on 6th row (3rd row for black)

Notes

Unlike many other variants that try to reduce drawrate and opening bias by massively increasing the complexity, this variant achieves the goal by making the game less inherently drawish and actually reducing complexity. Testing with Fairy-Stockfish (both old handcrafted eval, and current nnue) shows very low draw rate and no opening bias.

This game has both strategical and tactical complexity.

Creating strong structures is a must to keep the king safe but the game can be over in a moments notice if someone misses tactics. Opening variety is high.

The knight is a scary piece.
