Makruk starting position

Makruk (Thai: หมากรุก, pronounced [màːk rúk]), or Thai chess, is a board game that descended from the 6th-century Indian game of chaturanga or a close relative thereof, and therefore related to chess. It is regarded as the most similar living game to this common ancestor of all chess variants.[1]

There are around two million Thais who can play makruk, while 5000 can play chess.[2]

According to former world chess champion Vladimir Kramnik, "Makruk Thai is more strategic than international chess. You have to plan your operations with total care since Makruk Thai can be compared to an anticipated endgame of International Chess."[3]

  • The pawn (called เบี้ย bia, a cowry shell, formerly used for money) moves and captures like a pawn in international chess, but cannot move two steps on the first move and, therefore, cannot be captured en passant. A pawn that reaches the sixth rank is always promoted to a queen (med).

  • The queen[4][5] (called เม็ด met, seed[4]), arguably the weakest piece, moves one step in any diagonal direction, like the fers in shatranj, or a cat sword in dai shogi.

  • The knight (called ม้า ma, horse) moves like a knight in Western chess: two steps in one direction and then one step perpendicular to that movement. It jumps over any pieces in the way.

  • The king (called ขุน khun, meaning either a feudal lord or a title-holder of the lowest ranks in the ancient Thai nobility) moves like a king in international chess - one step in any direction. The game ends when the king is checkmated.

In starting position, pawns are placed on the third and sixth ranks. Queens are placed at the right side of kings. Pawns promote (เบี้ยหงาย bia ngai, flipped cowry shell) and move like queens when they reach the sixth rank. There is no castling rule like that of international chess.

Counting rules

Makruk Thai players

When neither side has any pawns, the game must be completed within a certain number of moves or it is declared a draw. When a piece is captured the count starts again from scratch only if it is the last piece of one side in the game.

  • When neither side has any pawns left, mate must be achieved in 64 moves. The disadvantaged player does the counting, and may at any time choose to stop counting. If the disadvantaged side 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 side is captured, the count may be started, or restarted from the aforementioned counting, by the weaker side, and the stronger side 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 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 or bishops or knights left, but only queens: 64 moves

The weaker side pronounces aloud the counting of his fleeing moves, starting from the number of pieces left on the board, including both kings. The stronger side has to checkmate his opponent's king before the maximum number is pronounced, otherwise the game is drawn. During this process, the count may restart if the counting side 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 the king.

Variants

Here are some alternative 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 (see below).

  • Sut Khun สูตรขุน (King Sutra) can be compared to the castling rule in international 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 never 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 Pawn in front of the Queen at the same time. Two pieces are moved in this sutra. First, move the Pawn in front of the Queen forward; then move the Queen to the blank square the pawn has just vacated, so the Queen moves two squares.
  • Sut Ma สูตรม้า (Knight Sutra) is a first free move that allows the player to move a Knight and a Pawn a Knight's move from that Knight in the same turn. Two pieces are moved in this sutra. First, move the Pawn which is a Knight's move from the Knight forward; then move the Knight to the blank square the Pawn has just vacated.
  • Takhaeng Ruea ตะแคงเรือ (Boat Tilting, Boat Lean) Turn one or both Boat pieces upside down. This changes the Boat to be a Bia Ngai (flipped cowry shell). This reduces the power of one or two Rooks.

Cambodian chess

Cambodian men playing Ouk

The variety of chess played in Cambodia, called "Ok" (Khmer: អុក)[7] or "Ouk Chatrang",[8] is virtually identical to makruk, with a couple of minor differences.[9] If no pieces have been captured, the players have the options

  • on the king's first move, and only if not in check, of moving the king like a knight; and
  • on the queen's first move, of moving the queen two squares straight ahead.[8]

There is evidence that Ouk Chatrang has been played in Cambodia since the twelfth century, as it is depicted in several reliefs in the Angkor temples.[9]

Ka Ok

In the variant "Ka Ok" (aka "Kar Ouk"), the first player to put the other in check wins.[7]

Tournament

The first Ouk Chatrang tournament was held in Cambodia from April 3 to 4 of 2008, upon the completion of a standardized ruleset by the Olympic Committee of Cambodia and the Cambodian Chess Association.[10]
