Grand Chess - A Variant with Fairy Pieces

Board:

Grand Chess setup


Main Rules:

The game is played on a 10 x 10 board, with additional files for the new Marshal (Knight/Rook) and Cardinal (Knight/Bishop), which are both placed on the king side. Because of the larger board size, most of the starting pieces are moved up one rank, with the exception of the rooks which remain in the last ranks.

In addition to the pieces and setup, there are three other significant differences:

  • Pawns can promote when reaching the eighth or ninth rank. Promotion must happen upon reaching the 10th rank. If not possible (see next point), then the pawn can’t move.
  • Pawns can only promote to pieces of the same color that have been lost.
  • There is no castling.

Special Piece 1: The Marshal

The marshal is a piece that can move like a rook and knight combined. When writing the move use the letter M. e.g. 1. Mg4 or 1. Md1 MarshalAbove are some examples of how the marshal looks.


Special Piece 2: Cardinal

The cardinal is a piece that can move like a bishop and knight combined. When writing the move use the letter C. e.g. 1. Cf4 or 1. Ch1

Cardinal

Above are some examples of how the cardinal looks.


Strategy:

Relatively little is known about many of the variants here. Creativity and attention to detail are always important. And so the following advice is tentative.

Try not to make "routine" developing moves. Sometimes it is worth spending more time to reposition fewer pieces optimally, rather than to develop many pieces suboptimally in less time. Even the variants which appear to resemble chess cannot be played with routine chess moves for very long.


Whoever answers the below tactic correctly first will be the first contestant to play with me. Explanation required for points. Good Luck!!!

Anyone have the answer? If you want to play but don't have the answer, let me know in this forum so that I can post the answer.

cardinal takes queen for free

GM_multimortar4500

the bishop-knight doesn't currently control the queen

M_Svat

@GM_multimortar4500, it is black to move, should it trade the queen for the marshal?

Time Control: 3 Days/Move You can play white or black your choice. If you choose white, make your move. If you choose black, just tell me.

M_Svat

This is an already invented variant. I like to call the princesses Chancellor and the Cardinal Archbishop tho.
