Brusky's Hexagonal Chess

Yakov Brusky invented this game in 1966. It is an adaptation of Chess to a hexagonal board. So, it follows the rules of Chess except where the new geometry requires some modifications. Because the board has three colors instead of two, each player gets three Bishops instead of two. Due to the greater width of the Pawn ranks, players also get some extra Pawns.



Brusky's Hexagonal Chess is played on a hexagonal board with horizontal ranks and slanting files. There are two sets of files, but only one is needed for notation. The convention used in this game is to give the same file label to the spaces in left leaning files. So, for example, the left leaning file from White's left corner is a1-a2-a3-a4-a5, whereas the right-leaning file from the same space is a1-b2-c3-d4-e5-f6-g7-h8. This difference has no effect on how pieces move and is only a convention for establishing a system of notation. This board has 12 files and 8 ranks. Files d through i cover all 8 ranks, but a covers only ranks 1 to 5, b covers only ranks 1 to 6, c covers only ranks 1 to 7, j covers only ranks 2 to 8, k covers only ranks 3 to 8, and l covers only ranks 4 to 8. This gives the board a more symmetrical shape than the parallogram it was cut out of, leaving it with only 2*5 + 2*6 + 2*7 + 6*8 = 84 spaces.

At each end of the board, each player has a rank with 9 spaces. From each player's left to the same player's right, each player has a Rook, a Knight, a Bishop, a Queen, a Bishop, a King, a Bishop, a Knight, and a Rook. The next rank has 10 spaces and is filled with Pawns. This setup gives the game rotational symmetry, meaning each side looks the same when the board is rotated 180 degrees.


Except for details concerning castling and Pawn movement, the pieces in this game move exactly like the pieces in Glinksi's Hexagonal Chess.


The King moves ones space in any orthogonal or diagonal direction. Orthogonal directions go through the sides of spaces, and diagonal directions go through the corners of spaces. With six sides and six corners, the King can move in up to 12 different directions.


For King-side castling, the King moves two spaces toward the Rook, and for Queen-side castling, the King moves three spaces toward the Rook. Apart from moving further for Queen-side castling, castling works the same as it does in Chess. The Rook moves to the space adjacent to the King on its other side, and all usual castling conditions apply.


The Rook may move any number of spaces in any orthogonal direction until it reaches an occupied space.



The Bishop may move any number of spaces in any diagonal direction until it reaches an occupied space. As in Chess, Bishops are colorbound. Unlike Chess, the board has three colors, and each player has three Bishops to have one for each color. Because each Bishop can reach only one third of the board, a Bishop is less powerful than it is on the Chess board, where it can reach half the spaces.



The Queen moves as a Rook or a Bishop. Note that it can reach any space in its third perimeter, which it cannot do on a square board.



The Knight can leap directly to any space in its fourth perimeter that a Queen cannot reach. As in Chess, each space it can leap to is one that could be reached by moving one space orthogonally, followed by one more space in an outward diagonal direction. Besides not including the inward diagonal directions, outward diagonal directions do not include the sideways diagonal directions that would turn the piece a full 90 degrees.





This game follows the rules of Chess in every respect except those already described above.


This description of the game is based on the section about the game in the "HEXAGONAL C" article of the first edition of D. B. Pritchard's book The Encyclopedia of Chess Variants, and it follows it in every detail. As mentioned above, I had to play out one of the included games to confirm one interpretation of the rules. The chapter on Boards based on Hexagons in The Classified Encyclopedia of Chess Variants leaves out some details and applies the same system of notation to every hexagonal variant despite it not being historically accurate. In researching the rules, I checked out different programmed versions of the game, and I found that none of these got the rules 100% correct.

Board Images

Here are blank board images you can print out and use to play the game with small Chess pieces. I will link to the Diagram Designer to make it easy for you to modify them before printing. You should print the board in landscape at the maximum size that will fit the page. This was 145% for letter size when I did it.
