Chess variants (first of a series)

By Frank “Boy” Pestaño

It is a credit to the popularity of chess that there are hundreds of variants of the game and a new one is invented almost every year somewhere in the world. In this series, I will mention only those variants that are original or classic, popular and long lasting. This means the original author has long passed away and cannot promote it anymore.

Shogi is the original or classic variant, and is very popular in Japan. XiangQi is also called Chinese chess, which is played in China, Korea, Taiwan, Vietnam, Hong Kong, Singapore, Thailand and even here in the Philippines.

Shogi is played on a 9x9 uncheckered board and the pieces have the same color. Its enduring popularity can be attributed to its “drop rule,” meaning the captured piece can be returned to the board and used as one’s own, a practice in 16th century Japan where captured mercenaries switch loyalty.

Each player begins with a king, a rook, a bishop, two gold generals, two silver generals, two knights, two lances and nine pawns. Since the pieces have the same color, loyalties are determined by their directional headings.

The King, Rook and Bishop moves are the same as chess. The pawn moves a square forward and captures in the same manner as they move. The gold general may move one square vertically, horizontally or diagonally, except diagonally rearward. The silver general may move one square in all directions except horizontally or straight rearward.

The knight has the two forward-most moves as the orthodox knight. For example a knight on d5 may go to c7 or e7. The lance has the forward-most move of the orthodox rook, keeping always in the same file.

The main difference with orthodox chess is the manner of promotion of the pieces. The silver general, knight, lance and pawn are promoted to gold general. The rook promotes to a dragon king, which has the combined moves of a king and a rook. The bishop promotes to a dragon horse, which has the combined moves of a king and a bishop.

There are other rules but the object of the game is to checkmate the enemy king just like in orthodox chess.

The XiangQi board is made up of 10 horizontal and nine vertical lines. The verticals are interrupted by a central-horizontal void called a river. Two palaces, black and red, are at opposite sides of the board and is distinguished by a cross connecting its four corner points.

Each side has two chariots or rooks, two knights or horses, two elephants or bishops, two mandarins or advisors, one king, two cannons and five pawns or soldiers.

The king can move one square vertically or diagonally and can’t leave the palace even to avoid checkmate. There is no castling. The mandarin moves one square diagonally and restricted to five of the nine squares in the palace.

The bishop moves two squares diagonally but can’t jump. It can’t cross the river. The knight moves like the chess knight but can’t jump. The rook moves like a chess rook.

The pawn moves one square forward and can move diagonally when it crosses the river. It can’t be promoted to a mandarin and can never move backwards.

The cannon is unique. It moves like a rook, captures like a rook and can jump over a piece. There must be exactly one piece between the cannon and the piece it captures. The intervening piece is known as the gun mount.

The object of the game is also to checkmate the enemy king.

I will be discussing more variants in my subsequent columns.

SEAG TEAM. The members of the Philippine team to the Southeast Asian Games under the standard time category (one hour and 15 minutes time control) are Grandmaster Joey Antonio, National Master Oliver Barbosa, Fide Master Oliver Dimakiling, International Master Ronald Dableo and IM Jayson Gonzales. GM candidate Mark Paragua did not make the team as he had a heartbreaking loss in the last round against FM Fernie Donguines.

The Women’s team includes Woman IM Sherrie Joy Lomibao, WNM Shercila Cua, WIM Beverly Mendoza and WNM Aices Salvador.

Cebuanos Richard Bitoon and Therese Gonzales failed in their quest although they still have a chance, as there will be another group of players under the active time control format.

CEPCA SUNDAY. “Expect the unexpected” best describes the Cebu Executives and Professional Chess Association (Cepca) tournament last Sunday at the Stella Maris Seafarer’s Center in Pier 4. Civil Service Commission-Cebu head Fabio Abucejo culminated his string of upsets with a final-round win over Pepe Gador to win the July edition of the club tournament.

El Labunog placed second with a win over eventual third-placer Jun Olis, while Maggi Dionson and this writer were fourth and fifth, respectively.

We also had a new member, Engr. Pericles Fernandez of Pepsi Cola. Welcome to the club, Prix.
