Makruk

(Redirected from Khmer Ouk)

Makruk (Thai: หมากรุก; RTGS: mak ruk;[1] pronounced [màːk rúk]), or Thai chess (Thai: หมากรุกไทย; RTGS: mak ruk thai; pronounced [màːk rúk tʰaj]), is a strategy board game that is descended from the 6th-century Indian game of chaturanga or a close relative thereof, and is therefore related to chess. It is part of the family of chess variants.[2]

In Cambodia, where basically the same game is played, it is known as ouk (Khmer: អុក, pronounced [ʔok]) or ouk chatrang (Khmer: អុកចត្រង្គ, pronounced [ʔok.caʔ.ˈtrɑŋ]).[3]

Origin

edit

The Persian traders came to the Ayutthaya kingdom around the 14th century to spread their culture and to trade with the Thai kingdom. It is therefore possible that the Siamese makruk, in its present form, was directly derived from the Persian game of shatranj via the cultural exchange between the two peoples in this period. This is because the movement of makruk's queen, or the "seed" (Thai: เม็ด), is essentially the same as the ferz in shatranj.[citation needed]

However, it is more likely that the game came more directly from India given the name similarities between chaturanga and the Cambodian name, ouk chaktrang (Khmer: អុកចត្រង្គ), and the way the "nobleman" (Thai: โคน, Khmer: គោល) moves.[4][3] In his History of Chess, Murray suggests it may have followed the expansion of Buddhism in the area.[4]

Pieces

In the starting position, cowrie are placed on the third and sixth ranks. Queens are placed at the right side of kings.

  • The cowrie shell moves one space forward and captures one space diagonally forward. Unlike in Western chess, the cowrie cannot advance two squares on its first move; therefore, it cannot be captured en passant. A cowrie that reaches the sixth rank is always promoted. It becomes a "promoted pawn" (เบี้ยหงาย bia ngai, in Thai, meaning overturned cowrie shell), which moves one square diagonally in any direction, like the queen. cowrie promotion is usually denoted by flipping the piece over.

Counting rules

edit

When neither side has any cowries, the game must be completed within a certain number of moves or it is declared a draw. When a piece is captured the count restarts only if it is the last piece of a player in the game.

  • When neither player has any cowries left, mate must be achieved in 64 moves. The disadvantaged player counts, and may at any time choose to stop counting. If the disadvantaged player checkmates the advantage side and did not stop counting, the game is declared a draw.

When the last piece (that is not the king) of the disadvantaged player is captured, the count may be started, or restarted from the aforementioned counting, by the weaker player, and the stronger player now has a maximum number of moves based on the pieces left:

  • If there are two rooks left: 8 moves
  • If there is one rook left: 16 moves
  • If there are no rooks left, but there are two bishops: 22 moves
  • If there are no rooks or bishops left, but there are two knights: 32 moves
  • If there are no rooks left, but there is one bishop: 44 moves
  • If there are no rooks or bishops left, but there is one knight: 64 moves
  • If there are no rooks, bishops or knights left, but only queens: 64 moves

The disadvantaged player announces the counting of his fleeing moves, starting from the number of pieces left on the board, including both kings. The winning player has to checkmate his opponent's king before the maximum number is announced, otherwise the game is declared a draw. During this process, the count may restart if the counting player would like to stop and start counting again.

For example, if White has two rooks and a knight against a lone black king, he has three moves to checkmate his opponent (the given value of 8 minus the total number of pieces, 5). If Black captures a white rook, the count does not automatically restart, unless Black is willing to do so, at his own disadvantage. However, many players do not understand this and restart the counting while fleeing with the king.

Variants

edit

There are rules which do not apply to the standard, formal game, or have been abandoned in professional play. They are called sutras. The first free moves are similar to those in Cambodian ouk.

  • Sut Khun สูตรขุน ("King Sutra") can be compared to the castling rule in Western chess. The rule allows the player to move the king to a blank square on next row, like a knight, so long as the king has not yet moved.
  • Sut Met สูตรเม็ด ("Queen Sutra") is the most popular sutra in informal rules. It is a first free move that allows the player to move the queen and the cowrie in front of the queen at the same time. Two pieces are moved in this sutra. First, move the cowrie in front of the queen forward; then move the queen to the blank square the cowrie has just vacated, so the queen moves two squares forward.
  • Sut Ma สูตรม้า ("Knight Sutra") is a first free move that allows the player to move a knight and a cowrie a knight's move from that knight in the same turn. Two pieces are moved in this sutra. First, move the cowrie which is a knight's move from the knight forward; then move the knight to the blank square the cowrie has just vacated.
  • Takhaeng Ruea ตะแคงเรือ ("Boat Tilting, Rook Tilting") involves turning one or both rooks upside down. This changes the rook to be a queen. This reduces the power of one or two rooks.

Cambodian chess

Cambodia has a variant of chess that was introduced in southeast Asia centuries ago, called ouk (អុក [ʔok])[5] or ouk chaktrang (អុកចត្រង្គ[6] [ʔok.caʔ.ˈtrɑŋ] or [ʔok.cat.ˈtrɑŋ]),[3] with minor differences to the Thai version of chess.[3] In Vietnam, ouk is called cờ ốc, meaning "shell chess", as the shape of the pieces resemble shells.

The main rules difference involves the first movement of the king and queen. If no pieces have been captured, the players have these options:

  1. On the king's first move, and only if not in check, of moving the king like a knight; and
  2. On the queen's first move, of moving the queen two squares straight ahead.[3]

There is evidence that ouk has been played in Cambodia since the twelfth century, as it is depicted in several reliefs in the Angkor temples.[3]

The first nationwide ouk tournament was held 3–4 April 2008, upon the completion of a standardized rule set by the Olympic Committee of Cambodia and the Cambodian Chess Association.[7]

In a variant known as kar ouk (also known as ka ouk), the first player to put the other in check wins.[5] Another variant of Cambodian chess was described by David Pritchard in the first edition of The Encyclopedia of Chess Variants, but this was later determined to have been included in error as no such game was played in Cambodia.[8]

Ouk is one of three traditional sports introduced by Cambodia at the 2023 Southeast Asian Games, along with the martial arts of Bokator and Kun Khmer.
