Hello,

In your club, which are the dimensions of the xiangqi chessboard and the diameter of the pieces that you use?
I would want to buy myself a set of the game but beforehand, I would want to know the sizes that habitually are used.

You are cordially invited to join the new tournament of the fellowship "Oriental games" opened to all.
The supported games are:
Chess, Chinese Chess, Japanese Chess, Loop chess, Ambiguous Chess, Reversi 8x8, Go, Go 9x9 and Go 13x13.
You can be registered to the adress:
Oriental Games (15. Septembre 2006, 06:56:47)

Five more players needed to start this Chinese Chess Elimination Tournament:

LOSE A GAME AND YOUR OUT

Please come and join!

There is such a rule (although I don't find it written down ). If there are 50 moves played without taking a piece the game should (can, must???) be declared draw.

I see mention of a 50 move rule below (by Chicago Bulls). However, I don't see it mentioned in the BK rules. Is there such a rule in chinese chess, and if so under what conditions does it apply?

Within the fellowship Xiangqi, we began a game of Xiangqi in educational matter which sees to be opposed a team of players to a player of good level.
The choice of each move of the team is done
after debate and it is that which is very enriching to progress in the knowledge of the tactics and the strategies of the game. We have besides also within the team of good players who by their comments bring to us much.
If you are interested to take part in this action, it is enough that you make the request to enter the fellowship "Xiangqi" to the address :
http://brainking.com/fr/ShowFellowship?fid=429

Come many, you will be welcome.

Hello,

Following the abandonment of the preceding president of
association "Xiangqi" of this site, I became the new president.
If you want to become member of this association, do not hesitate to make the request at the address :
http://brainking.com/fr/ShowFellowship?fid=429

Due to the change in membership status of the previous moderator of this board, it needs a new moderator.

Anyone interested, please send me (or any Brainking Staff member), a message indicating your interest. We will choose from the messages received. Some knowledge of the game is of course preferred! :-)

Lordi: When I first began to play XiangQi I asked the question about enough material to win- and a much more experienced player told me that the basic rule is that to win I would need one more attacking piece than my opponent had defenders. I have found that it works a s a rule of thumb. My king of course is always an attacking piece.

Beren the 32nd: King + one soldier against King is a win because the stalemate in XianQi is a win. Chariots, Horses, Canyons, Soldiers and the King too can attack to the opponent king. Elephants and Advisors just can defend.

Matarilevich: Thanks. That sounds pretty definite. But I guess having an extra soldier, elephant or advisor is not normally enough to get a win is it?

Beren the 32nd: If you get a chariot for a horse (canyon) and your opponent doesn´t get any compensation in exchange for it, then you get an enough advantage for winning the game.

Can anyone share their experience on this question? If I win a chariot for a horse or cannon early on in the game, should this normally be enough to win the game (if I play well) or does my opponent often have chances to draw (if he plays well)?

panzerschiff: I have a thin plastic board that came with my large pieces and have yet to find a suitable wooden version. I will look next time I'm in China, but the only wooden ones I ever saw were the ones in the parks where these large pieces were used.

Do you play Chinese Chess?
Do you have a Xiangqi-BKR below 1800?
Do you want to win a 1-Year-Rook-Membership?

Then this is the right tournament for you! Just join and try to be the best - the winner takes it all!

In order to keep the competition within the targeted rating range, three special rules will be enforced:

- No unrated players!
- Players whose BKR goes over 1799 until the start of the tournament will be removed!
- Players whose highest published BKR has been 1900 or above will be removed!

Xiang-Qi

starts automatically as soon as 8 players registered

Several months ago I bought a set of Xiangqi disks roughly 2 inches in diameter. Yutropian who I bought them from did not have a board to accomodate such large disks and I never came across anything on the internet in my google searches to accomodate such large disks. Anybody know of a source to buy a board that would fit these pieces?

The Tournament: Chinese Chess Extravaganza (Chinese Chess) is finished.

Winner of the tournament: gringo

I have created a Xiangqi-Tournament, which can be joined by everybody interested:

http://brainking.com/en/Tournaments?trg=14196&trnst=0&u=19298

No prices, but a lot of fame to win!

Hi,

if you are rated below 1900 resp. below 1300 then these two tournaments might be interesting for you:

below 1300 (open until 06/02/20)

below 1900 (open until 06/02/26)

Come on and join!

interesting in asian rules mentioned is :

The side who violates a rule, asked by the referee to alter, and repeats the violation for three times will be ruled to lose.

Pythagoras: the rules are very difficult to implement. Even if it seems quite easy for check-check-check-check with the same piece, it will be much more difficult to understand for chasing. If you attack a protected piece of the same value, than it is no more chasing. If you chase than chess than chase it is -apparently- legal. So quite a nightmare to implement (and to understand). I guess a way to "request draw" is probably the best, because most of the situations can be quickly judged by Fencer.

Pythagoras: that number is another subject for tests
maybe if more than 3 checks, in chess start to drop the score toward draw slowly, in xiangqi exclude this condition if trapped by repetition

Well it was my fault too since i used the normally in the wrong place.
Instead of: "this can't be done normally" i should have used: "this normally can't be done"....

Pythagoras: ah, sorry, didn't read carefully enough. I thought you wouldn't give this case any importance.

gringo: I know that's why i put "normally" in what i've said....

Well I think I don't need to write the rules down as they are all here: http://www.clubxiangqi.com/rules/asiarule.htm

(the link I already mentioned)

Pythagoras: Sorry Pythagoras, but I think you are not totally right. E.g. because of the cannons it's an everyday's situation to answer a check with a check. The situation mangue mentioned is a draw, as both players violate the rules and it doesn't matter which player began:

http://www.clubxiangqi.com/rules/d4.htm


Another thing: At IYT they programmed, that its forbidden to check more than three times by moving the same piece, which is complete nonse, because you often need to give some hidden checks (with cannon and horse eg.), where you take several opponents pieces with every hidden check. So the important point is, if there is a notable progress in the position or not...

If I find the time this evening I will write down the repetition rules as far as I know them.

mangue: Gringo maybe can confirm, but perpetual check lose the game for the attacker, but as the link he references, the rules are so complex, than it is very hard to apply (would require an expert in XiangQi and lots of hours).

The rules are straightforward! Nothing complicated i see..... Also this rule for King checks is valid always:
Under any circumstance, the side that perpetually checks with one piece or several pieces, will be ruled a loss.


if you do perpetual chess, and your opponent too (that is you defend a check with a check),

This can't be done normally, since you have to resolve the check (that means to get out of check) before playing another check to the opponent....

Anencephal: Checks in a row by a piece or multiple pieces.

This is not well defined....

At least 2 Checks in a row by a piece or multiple pieces.

At least 3 Checks in a row by a piece or multiple pieces.

3 Checks in a row by a piece or multiple pieces.
That is well defined situations.
Normally after 2-3 checks i a row, that repeat the same position periodically, should be a valid way to program it.....

If a player repeat checking or chasing or threatening mate, you can send him a warning, and if he does again, he will lose the game.

Gringo maybe can confirm, but perpetual check lose the game for the attacker, but as the link he references, the rules are so complex, than it is very hard to apply (would require an expert in XiangQi and lots of hours).

Ex: if you do perpetual chess, and your opponent too (that is you defend a check with a check), than it is draw ! well, the "asian rules" are very complex, and Fencer it is up to you to define a "simpler" variant

Checks in a row by a piece or multiple pieces.

As repetition detection has a desirable effect on move tree in an engine, I was thinking about cost vs benifit of perpetual check detection

Repetition will capture some of them, and king movement is limited in Xiangqi

Anencephal: What do you mean about perpetual check? How do you define it?
Eveything that is well defined it is programmable....

I'm interested in programing aspect of it. Repetition is easy to detect efficiantly but i had not thought about perpetual check. seems tricky.

Fencer: but still easier than to program it.

gringo: Because it's more complicated in Xiangqi, instead of declaring a draw I would have to ask the player to stop doing the repetition moves because it's against the rules. And if he refuses to do it, I would have to solve it again.

Fencer: And that is the correct handling of the situation. There is not an automated draw call after a 3-fold repetition (repetition of the same position for 3 consecutive or non-consecutive times)! The player should claim the draw to the opponent first, when 3-fold or 50 move rule criteria appear and if the opponent doesn't agree then it should be claimed to you! If he doesn't offer the draw and plays one move, he loses the right to do it..... So if a player wants a draw after a 3-fold repetition or by 50 move rule, he should claim that before he plays his move to the opponent....

Same occurs to Chinese Chess.

Fencer: So then why not keep it like this in Chinese Chess?

Anencephal: No, it was never necessary. According to exact rules of Chess, such situation must be reported to the tournament director [me] who decides if a draw should be declared or not.

Fencer: Does BrainKing detect threefold repeatition in Chess?

gringo: Maybe I should code a virtual judge? We could use some kind of an artifical intelligence here.

As kleineme mentioned the repetition rules are a bit complicated. Official rules are to be found here:

http://www.clubxiangqi.com/rules/asiarule.htm


Judgement of some typical situations here (end of the document):

http://www.clubxiangqi.com/?F=rules



In Chinese Chess does not exist a strict rule like "3-time repetition is draw (or loss)". In a tournament the judge will call the players to alter their moves and only if they don't he will judge the game a loss or a draw. A game would be draw e.g. if both players play "allowed" moves, e.g. such with which they don't attack any pieces.

Have you implement(coded) the 3-checks in a row to automatically declared as a loss or better to prevent a player for playing a 3-check in a row as an illegal move.....?
Also if yes, does the implementation uses the 3 check in a row by the same piece or by various pieces?

DragonKing: No computer understands the term "perpetual". It must be defined in a discrete math, for example 3 checks in a row (with the same position of all pieces) can be taken as a perpetual check.

kleineme: Correct!

DragonKing: That's a question which has to be answered by Fencer. Such a feature certainly would be desirable but the rules, especially for perpetual chasing, can be quite tricky. Anyway I don't think that it's an urgent matter on a turnbased site because first you can inform your opponent about the rules, and if that doesn't help then you can always message Fencer and ask him to take measures. That is if you know the rules ;) If you don't and you agree to a draw because you think the same rules as in western chess apply then it's too late ;)

kleineme: Is it possible to change the software program so that perpetual check and perpetual chase would not be allowed? It would certainly improve the program and make for a better playing experience for everyone.

Hi,

seeing that there are still draws by perpetual check, recently in these two games:

http://brainking.com/en/ArchivedGame?g=1160405
http://brainking.com/en/ArchivedGame?g=1049399

I think it makes sense to repeat an important rule: Contrary to western chess perpetual check is not allowed in chinese chess, as it is explained under "Other important rules" on the rules page: http://brainking.com/en/GameRules?tp=68

I want to get better in Chinese Chess
is there anyone,who want to teach me the game,
in a practise-game???

DragonKing: Settings / Xiangqi.

Is it possible to play here with traditional pieces? I found it easy to learn them especially after a few games and I dislike the western style.
