09 Castling (%) is not permitted (%K, %AD).
10 Laborious endgames are
avoided by the following rules:
10A When a player has no ROs,
ETs or KTs, h/er opponent must checkmate in a prescribed number of moves. The prescribed number of
moves is dependent on the number of MPs that the other player has on the
board.
Above: my name is Nawapol Paibool, I was the winner of
the Thai Chess Tournament at school this year.
I have been playing for two years.
My father taught me how to play and I play with him often. I like to play chess very much because it is
good exercise for my brain. In
10B If your opponent has RO1 and
RO2 then checkmate must occur in 8 moves.
10C If your opponent has one RO
then checkmate must occur in 16 moves.
10D If your opponent has ET1 and
ET2 then checkmate must occur in 22 moves.
10E If your opponent has one ET
then checkmate must occur in 44 moves.
10F If your opponent has KT1 and
KT2 then checkmate must occur in 33 moves.
This year we had just over 40 students
interested in the ‘World Chess Tournament’.
It is not so easy for us to find boards for this version of chess as
most people only play Thai chess. So,
all of the early rounds were played on the computer over a period of five
days.
10G If the opponent has one KT
then checkmate must occur in 66 moves.
10H The above checkmate rules take
no account of ADs.
11 Stalemate (++ST) is
considered a draw.
12 The KI, ROs (RO1 and RO2),
KTs (KT1 and KT2) are the exact same as used in traditional chess. There is a lack of vector MPs
[QU and BSs - long-range].
13 AD1 (Adviser)
moves one cell diagonally forward or back.
14 2
Elephants. ET1
and ET2 move one cell diagonally or, can move one cell forward (changing from the XL to
the XD cells in the process). Note: to
account for the slight difference in the moving ability of ET1, ET2 (used in Burmese
chess) and EL1, EL2 (used in Shatranj) a different monogram is used. Both types of MP are
Elephants.
15 Each side has 8 mps. Pawn-Thai: PT1, PT2, PT3, PT4, PT5, PT6, PT7
and PT8.
On
We selected 18 of our best students
from both the Primary and Secondary school.
The competition started at four in the afternoon with Mr. Tim walking
around the room playing one piece at a time.
Once Mr. Tim had made his move, the
students were given about 1-2 minutes thinking time as it took Mr. Tim a little
while to walk around the room making one move on each of the 18 boards.
On his return, the students had to
make their move straight away. They
weren’t allowed to move while he was elsewhere. The students really enjoyed the two hour
exhibition even though none of them were winners. This has now become an annual event. We look forward to meeting Mr. Tim again in
2001. Please click here for
pictures from the 1999 Exhibition.
16 A PT does not have the option
of moving two cells on the initial first move (FMO).
17 A PT captures just like a PA. The ‘en passant’
move is not available.
18 A PT is promoted on
reaching the promotion cells in the opponent’s half of the board.
19 The ISP of
the PTs is shown in the diagram below.
All games of Thai chess commence by placing the mps in
this manner.
20 The MPs are placed on rank-1
(for :A) and on rank-8 for :B.

21 The objective of the game is
to checkmate the opposing KI.
22 The opening set
of moves (:&O) are leisurely due to not having any vector MPs (QUs and
BSs). :A and
:B avoid clashes until the development
stage is completed.
23 KT2 is
usually moved in front of the KI.
24 KT1 is
placed beside KT2 on $F03 for :A and on $C06 for :B.
25 A-AD1 is
placed on $E03 for :A and on $D06 for :B (via $FO2 for :A and via $C07 for
:B). Thus, the ADs face the enemy KIs
(on the same file).
26 The ETs are placed beside the
KTs.
27 :A and
:B then advance on the KI-side of the board with the objective of forcing an open file.

This is the variant of chess which is most played in
The game is played on an uncheckered board of 8 x 8 cells. The pieces have large similarities to those
of the orthodox chess game, and make it from the description easy to play with
a normal set of pieces. I will describe
pieces with names of their ‘usual’ chess equivalent.
The opening setup is very similar to that of orthodox chess, with the
following differences: the positions of white KI and QU are reversed, and all PAs are on the third
and sixth row. So, the setup [ISP] is as
follows…….
White:
KI d1; QU e1; RO a1, h1; KT b1, g1; BS c1, f1; PA at a3, b3, c3, d3, e3, f3,
g3, h3.
Black:
KI d8; QU e8; RO a8, h8; KT b8, g8; BS c8, f8; PA at a6, b6, c6, d6, e6, f6,
g6, h6.
The KI, RO, and KT move as in orthodox chess, except that castling does not
exist in this game.
The QU moves one cell diagonally.
The BS moves one cell straight forward or one cell diagonally.
The PA moves as a normal PA, but may not make a double step on its first move [FMO]. When it reaches the sixth row, it promotes to a (Makruk)
QU.
Object of the game is to mate the opponents KI. Stalemate [++ST] is a draw. Also, when a player has no RO, BS, or KT
anymore, the other player must mate him/her within a certain number of moves,
depending on how many ‘big’ pieces the player has, otherwise the game is
declared a draw. The precise numbers
are omitted here. Also, my sources on
this seem to contradict - is there a native player of this game who can provide
full information on this topic?
The original names for the
pieces are…….
King: khun - leader. The Khun was
the lowest rank of conferred nobility in the Siamese court system (as opposed to inherited nobility).
Queen: Met - Pit or fruitstone. This
is the kerner of a fruit, like a cherry.
Bishop: Khon or Thon - Mask. The same
word means a kind of classical Thai royal drama, using such masks.
Pawn: Bia - cowry shell. Indeed
cowry shells were formerly used for PAs in Thai sets, as well as a unit of very
small money. You can take this as ‘PAs
equal small change’.
In some cases, for PAs cowry shells are used, who are turned over upon promotion. Similarities of this game, both with Chaturanga or Shatranj, and Shogi are
remarkable. Last century, special first
moves for KI and QU were allowed (the KI could make a KT move his first move,
and the QU could move two cells diagonally on her first move.) This practice seems to be no longer in use
currently. For additional information
the reader can consult The Encyclopedia of Chess Variants which has two pages on this game, including sample games and Thai notation.
