- I'm too lazy to login, but I'd like to note that shogi does occasionally get referenced in popular media. One good example is in the film version of Cowboy Bebop, where two lead characters play shogi in the beginning of the film, and later one of those characters chastizes the dog for moving one of the pieces. They dog actually has made a good move, but the humans he lives with don't know he's super smart.

A box set for the Cowboy Bebop TV series released in Japan a couple of years ago had a reference to shogi as well. Each DVD was in packaging that suggested it was another type of media. The 6th was made to look like a PS 2 shogi game. Very cute. http://image.blog.livedoor.jp/ariablu/23c9d7bd.jpg —Preceding unsigned comment added by 99.235.104.204 (talk) 02:30, 30 November 2008 (UTC)[reply]

Shogi

I've never played Shogi, nor seen it played, and have only a single book on it (Shogi: Japan's Game Of Strategy by Trevor Leggett). If anyone knows better, please correct any errors found in this article. -- Bignose

The game pieces are marked with Japanese characters; if someone could add the Unicode characters to this article this would be a great help. -- Bignose

Hi Bignose, thanks for doing the original Shogi page -- but whoever told you that the character for a non-promoted piece and the promoted version are the same never saw a japanese shogi set! Follow the link I put in the text... they're different. -- NickelKnowledge

chinese korean and japanese chess are not from indian.

Please explain. Cite sources saying they originated independently from the Indian variant. --129.241.103.90 10:36, 14 Jun 2005 (UTC)

I edited the article a bit, including the Japanese, added a couple game screenshots, some very basic strategy including the Yagura defense, etc. Sorry, 'anonymous' was me; I got signed out while editing. Hope these are all improvements and that I didn't introduce any errors.

Do we still need the Unicode values, now that Japanese can be entered directly into the edit window? It would be nice to get rid of them.

By the way, Bignose, this is a very fun game. I quickly came to prefer it over Western chess, not that I'm very good at either at either of them! kwami 11:24, 2005 July 16 (UTC)

Professional Players

The current article says The latest, most famous champion, Yoshiharu Habu, is said to earn more than 1,000,000$ each year. Are those US dollars? If so, then it should be $1,000,000. If not, then someone please note the currency.

Ah, I have done many spelling mistakes so far, but this one might be a bit serious. Of course they're US dollars. I've corrected it. Thank you. G.P. 11 January 2006

Professional title matches are broadcasted online by official sponsors. Most of the contents are in the Japanese language, but I think reenactment of matches by Java script are acceptable to everyone. So I would like to make some external links to them, but I don't know how they should be made, and if they should be made or not. I'm also worried that this may have little to do with shogi itself. How do you think?
( I've collected and kept them in my user page. Please check it if you are interested. ) Goblin princess 22:35, 16 February 2006 (UTC)[reply]

I think that's an excellent idea, GP. It would be nice if we could embed the javascript in an English-language environment, so as not to intimidate people, but at least the first game on your list was simple enough to browse without any knowledge of Japanese.
And of course this has everything to do with shogi! The challenge will be to find a professional match that illustrates points that even a novice can understand. I'm not sure if that's possible, but if it is we could have an analysis of why certain moves are important. For example, in that first game[1], move 82, Black's dragon horse is under attack. Black responds by attacking a gold with a pawn, and White defends that, rather than taking the horse. We could discuss why having a pawn break through the king's line is a more serious matter that capturing the most powerful piece on the board.
(PS. The phrase is "what do you think?") kwami 01:10, 17 February 2006 (UTC)[reply]
I just looked at that game for a brief glimpse to see what a normal game can look like. I was very confused about one thing though: Check out move #55. Black moves his bishop to 4-6 (6 being the Japanese numeral) and gets a Dragon Horse! That square is clearly NOT in the promotion zone. Was that even a legal promotion? The same thing happens in move #103 where he gets a Dragon King... --Sivak 06:41, 19 February 2006 (UTC)[reply]
Both start within the promotion zone: squares 7III and 8I, respectively. Any move that crosses the promotion zone in any way is a promotable move. It doesn't have to be entirely within the zone. kwami 18:10, 19 February 2006 (UTC)[reply]
I see... The way I read it is the piece still had to remain in the promotion zone upon moving to be allowed to promote. That actually makes a bishop and rook drop potentially even more deadly.
The right place for a promoted rook (Dragon King) is virtually always in the opponent's camp (thus in the promotion zone), whereas the promoted bishop (Horse) is a particularly strong piece for defensive purposes in your own camp although it is also used for attack. Cogitans 21:15, 3 March 2006 (UTC)[reply]
Let's take another example: If a silver was on row 6, moved to row 7 (the start of promotion zone), decided NOT to promote, then the opponent makes his move... Now: the Silver on row 7 moves BACK to row 6 it could still promote right then and there? --Sivak 20:53, 19 February 2006 (UTC)[reply]
Yes it can. Any move into, out of, or wholy within the zone can end in promotion. The only exceptions are the king, gold general, drops and pieces that are already promoted. A silver general can be droped on row seven, on the next turn it can move to row six and promote! JTTyler 23:36, 25 February 2006 (UTC)[reply]

Question on drops

This is minor, but is a pawn allowed to be dropped on a player's first or second row? I was curious if this is legal to do. I know the restriction rules are in play, i.e. a pawn not being able to be in the same file as another pawn, but was just curoius about this. --Sivak 05:07, 8 October 2005 (UTC)[reply]

Not minor when you're in a game! I believe it's legal. It's a common defence when someone breaks behind your lines. kwami 06:53, 8 October 2005 (UTC)[reply]

Second question about pawns

One other question: I know it's illegal to drop a pawn to immediately give checkmate to the enemy king, but is it legal if an unpromoted pawn is ALREADY on the board to move it forward and give checkmate that way?

Yes. --Zundark 07:43, 9 October 2005 (UTC)[reply]

minor mistake

"The Chinese characters have been deterred many people who are not familiar with them from learning shogi."

was not worded properly so I replaced it by this one

"The Chinese characters (kanji) have deterred many people who are not familiar with them from learning shogi."

Getting the article featured...

Well, I think it would be possible to get Shogi to be a featured article. What does the public think it needs? I personally think maybe an extra photo or two of real Shogi sets might help. I was thinking of maybe taking a photo of my set to show the different piece sizes and maybe we could add images of the pieces to their respective place in the move explanation.

Just some toughts. --Sivak 21:11, 22 October 2005 (UTC)[reply]

How about telling something about shogi professionals, computer shogi, etc.? See articles for Chess and Go for reference, they are both featured articles. -- someone

How about a photo of people actually playing shogi? The game is nothing without the people who play it, and they've been left out. kwami 00:53, 17 February 2006 (UTC)[reply]
Do you HAVE any photos? I actually have yet to play this game against someone... I've been playing the game of Go a bit though. --Sivak 06:58, 17 February 2006 (UTC)[reply]
For whatever it's worth, I have some photos of Western (more specifically Norwegian) amateur players in action during a fairly recent championship. Cogitans 21:03, 3 March 2006 (UTC)[reply]

Oushou vs. Gyokushou

This is a point worthy of bringing a modicum of attention to. There are indeed two kinds of kings (or "generals", disregarding the gold and silver) that you may find in a Shogi set, in their calligraphy only distinguished by the presence or absence of a single stroke. It is important to note that a set (or even Shogi diagram) does not necessarily consist of one of each. It is however a tradition of professional title matches for there to be a difference and for the holder to take the oushou (王) while the challenger takes the gyokushou (玉). Amateur practice is more likely to vary. Please note that this has nothing to do with being "Black" (sente, 先手, first to move) or "White" (gote, 後手, second to move). When a decision process for that is needed, "furigoma" (振り駒) i.e. a pawn toss is used. Cogitans 01:45, 4 March 2006 (UTC)[reply]

Noted. kwami 08:00, 4 March 2006 (UTC)[reply]

Pictures of the individual pieces

I know they've been up for a while, but I think it's neat that there are some pictures of real pieces and such. I noticed with the set shown that the promotion side is also in black, though with a more "stylistic" looking Kanji. I think I remember hearing it being Japanese calligraphy. Anyway, I was wondering if we could add a note about that in the article? Some sets use red for promoted pieces, but some don't. Mine doesn't use red either. --Sivak 05:11, 24 March 2006 (UTC)[reply]
It is not traditional to use sets with red for promoted pieces, I have never seen it in professional use. Cogitans 12:22, 25 March 2006 (UTC)[reply]

History

Some discussion of the history of shogi would be much appreciated! I'd contribute, but unfortunately all I know about shogi I learned from Wikipedia :) Ckerr 13:58, 19 June 2006 (UTC)[reply]

Internationalized Shogi

Please take a look at my website: The Elephant Chess Club scroll down webpage to see internationalized shogi set

I learned to play shogi when I lived in Japan from 1990-1994. I really enjoy playing, and tried to teach people the game when I returned to the States. Unfortunately, the Japanese writing was too intimidating for most people. I redesigned the shogi playing pieces so that they are identified with designs and symbols. Of course, the playing pieces are double-sided. The reverse sides have the color red included to indicate promotion.

Please let me know what you think.

Thank you, Michael

"The Chinese characters (kanji) have deterred many people who are not familiar with them from learning shogi."

“Westernized” shogi sets have been available in the U.S. for some time – I purchased one at least 15 years ago. Instead of kanji, the pieces have a letter from the Latin alphabet ('P' for pawn, 'K' for King, 'L' for lance, etc.) Each piece also has a diagram of how it can move. It has been said that, in Japan, such a set is regarded as “suitable for children.” SlowJog 00:38, 5 January 2007 (UTC)[reply]

Thank you for your comments. I think that the symbols on the internationalized version of shogi (shown on website above) are intuitive and create a shogi set which is cognitively accessible in the same way as Western chess and more naturally understood as opposed to using a more direct means of marking the pieces, such as with letters or arrows. Here is an introduction to play on YouTube. Shogi Lesson #1 ElephantChess (talk) 22:44, 29 April 2008 (UTC)[reply]

Spread Outside Japan

The article states that one of the reasons the game of go spread outside of Japan more than shogi did is that it originated in China. My understanding of the history of go in the U.S. is that although it did originate in China, go came to the U.S. primarily through contact with Japan. SlowJog 00:52, 5 January 2007 (UTC)[reply]

I think the main reason is that shogi pieces use ideographs while go stones are intuitive black and white. --72.75.61.27 07:25, 26 February 2007 (UTC)[reply]
Of the given comparisons between go and shogi as reasons for the difference in the spread of the two games outside of Japan, I agree with all the reasons except for one about the country of origin. SlowJog 00:38, 16 April 2007 (UTC)[reply]


I agree with SlowJog, the fact that Go originated in China is not a factor. Go spread to the West from Japan anyway (that's why we use the Japanese term Go and not the Chinese Weiqi). /David (21st of May 2008) —Preceding unsigned comment added by 131.111.230.104 (talk) 20:53, 21 May 2008 (UTC)[reply]

SPAM

So, I think most of these external links fall under at least one of the categories of things to normally avoid under WP:EL. I don't want to just go ahead and delete them all, but are there any that anyone feels really strongly should stay? --Selket Talk 20:49, 14 February 2007 (UTC)[reply]

I was adding a link to the External Links section, and saw a request to ask here first. It is a direct download link to a print and play version of the game (a rather nice one, I think). The file is free and released under public domain but carries the logo and contact information of the company in it. So, is it acceptable or considered spam? Should I remove it? --Isacvale (talk) 17:53, 10 January 2013 (UTC)[reply]

Computer Shogi

What about adding some or all of these links:

Johann Petrak 09:03, 25 March 2007 (UTC)[reply]

Ryuo champion Watanabe played Bonanza in 2007

The wikipedia article says “Watanabe commented after the game that he should have lost if Bonanza had played a defensive move before entering the endgame”. I read the translated comments of Watanabe on shogi-l. I did not read this comment. What is the source of this Watanabe comment?

The wikipedia article says the computer has an “awesome endgame ability”. Watanabe said the opposite “I learned from this game is that endgame technique apart from tsumi is still a challenge for the computer.”

The wikipedia article says “This game can be looked at as a clear example that computer Shogi, although still not perfect, has reached top pro level”. Watanabe said, “they are getting to be a match for professionals” which are much weaker than top pro level.

This wikipedia paragraph in the shogi article exaggerates the strength of computer shogi. Mschribr 18:48, 1 May 2007 (UTC) Mark Schreiber[reply]

Openings

In the strategy section, it talks about rook and bishop openings. I've read that the openings are usually classified as static rook, ranging rook and double ranging rook. Could anyone who knows more about this clarify this?AbcXyz 16:42, 5 August 2007 (UTC)[reply]

The rook is the most powerful piece, generally used to support an attack from behind and then move in. If left where it is at setup, you have a static rook opening. If you move the rook over to the left to support an attack there, that's a ranging rook opening. I have no idea what a double ranging rook is, since you only have one. kwami 05:31, 13 September 2007 (UTC)[reply]
Each side can broadly be static rook (2 file) or ranging rook (files 5-8). A more accurate definition is where the rook is with respect to the king. If both sides use a ranging rook, it's called a double ranging rook, so the game openings can be double-static, double-ranging or static-versus-ranging. The article doesn't say 'double ranging rook', but is it clear? Adam1729 00:28, 25 September 2007 (UTC)[reply]

Hoax

I don't have the book handy, but if my memory serves me well, John Fairbairn wrote of Shogi that the Japanese have changed chess "until it became the most fiendishly complex game any normal person might still be interested in playing." SlowJog (talk) 02:32, 15 February 2008 (UTC)[reply]

On strategy, the article contains the statement, "A silver general never needs to promote, and it is often advantageous to keep a silver general unpromoted." No further discussion of strategy explains why; and the article gives no citation. A discussion on the strategic advantage of keeping a crippled piece when additional range of movement can be added for free is required to support the assertion given. --John Moser (talk) 17:14, 12 August 2010 (UTC)[reply]

Is the "Kifu" recording system used to record Shogi games?

Kifu is the system for recording games of Go. Since pieces never move in Go once placed on the board, Kifu records a game by drawing a diagram of the board in the end position and numbering each piece to show on which move it was placed. The Kifu topic page was included in category Shogi, and said that it was also used for Shogi, but I see nothing on this page about it and I don't see how it would be applicable to a game where the pieces move about.

I've removed all references to Shogi on the Kifu page, but on the off-chance that it is in some way connected I'm leaving this request for more info here. Maybe Kifu is Japanese for "game record" or something and is a general term used by Shogi players? If it is relevant please update the Kifu page and its talk page accordingly, and the Shogi page as well; if it isn't please confirm here? Thanks. Lessthanideal (talk) 00:41, 28 January 2009 (UTC)[reply]


Kifu (棋譜) is a general term for game records in Japanese. The term is used for Igo and Shogi, and even chess notation is called Kifu in Japanese.74.229.156.101 (talk) 05:17, 30 July 2009 (UTC)[reply]

Move numbering

The article says that moves are numbered the same way as in chess; however, this is incorrect. Each individual move is counted as a move, whereas in chess a pair of moves is counted as one move. In chess style a typical opening would be 1. P-7f P-8d 2. S-6h P-3d. However, in shogi notation, it would be 1. P-7f 2. P-8d 3. S-6h 4. P-3d. I'm going to go ahead and correct this in the article.

5 Professional Classes C2-A and 6 Professional Dans 4-9

Can someone elaborate on Professional rank and class in the shogi article? What causes a professional to move up in rank from 4 dan to 9 dan? How many games does a 7 dan have to win to become a 8 dan? I heard there are professional classes C2 C1 B2 B1 or A? How do these professional classes relate to professional dan rank? What causes a professional to move up in class from C2 to A? When is a professional class A used and when is a professional 9 Dan used? Is there an elo rating system for shogi professionals? Mschribr (talk) 12:36, 19 January 2010 (UTC)[reply]

Requirements for achieving higher dan is discussed in this Shogipedia page, which is a translation of the promotion requirements page on the Japan Shogi Association's website. The lettered classes (C2, C1, B2, B1, A) are exclusively for the Meijin tournament, where every professional player competes in a league system to challenge the Meijin. Elaboration can be found on the Ranking League page on Shogipedia, which is based on each individual Class page on the the Meijin Tournament's website. 68.191.84.156 (talk) 21:43, 15 September 2010 (UTC)[reply]

Addition Request

On the Hungarian Wikipedia article for "sógi", there is a section about variants of the game, including a four-player line up. Would you like to add this into the English article? TIA. --KägeTorä - (影虎) (TALK) 10:27, 29 April 2010 (UTC)[reply]

checkmate end of game?

Since there's been some back&forth, it would be good to clarify. We say, "checkmate ... effectively wins the game. The losing player should resign out of courtesy at this point". That suggests what I've heard elsewhere, that it is the capture of the king which wins the game, not checkmate, even though it is rare to actually go this far. — kwami (talk) 21:32, 16 April 2012 (UTC)[reply]

I've left some references to this. In a way, it makes little practical difference, but it's not checkmate, it's not capture of the king, it's when someone resigns. (Or, for that matter, forfeits by time or illegal move.) You could try asking Hidetchi of the YouTube series of shogi videos about this; I think he's Japanese. OneWeirdDude (talk) 14:11, 19 April 2012 (UTC)[reply]

Piece value

Well. I happen to be quite new at this game. Just as chess have "point values" assigned to pieces to indicate piece importance. What are the numbers assigned to shogi pieces? Starting with the lowly pawn as 1. KyuuA4 (Talk:キュウ) 20:30, 11 June 2012 (UTC)[reply]

Pawn abbreviation = p or P

The chart and photo caption in section "Game equipment" use lowercase as abbreviation for pawn. But in section "Game notation", capital is used. Presumably abbreviations are used in notation. If so, then these should be consistent (otherwise confusing). I'm guessing that capital is correct ("Game notation"), and the abbreviation in chart and caption can be changed to capital. (I'm not a shogi player; is there any objection if I change it?) Thx, Ihardlythinkso (talk) 17:15, 19 July 2012 (UTC)[reply]

Greater complexity means harder for a computer to beat the best human

FalseAxiom, of course having greater complexity means that it is harder for a computer to be programmed to win. As a player looks at more ply down the tree then the player will pick a better move. As the complexity of the game goes up then there are more moves at each position to consider. As you look at more moves at each position then it takes longer to look more ply down the tree. Then the computer will look at fewer ply down the tree and the resulting move will be inferior. Therefore as the complexity goes up means that it is harder for a computer to be programmed to win that game compared to other games. --Mschribr (talk) 04:48, 27 September 2012 (UTC)[reply]

The complexity of the game affects both the player and the computer. In the game of Shogi, humans use advanced heuristics for pruning possible moves to avoid performing some computation, but, in general, that doesn't mean a theoretically complex game is easier for humans than for computers. Consider solving the traveling salesman problem, a computer is much more competent in that domain than a human is, despite the fact that it is in the class NP. The statement in the article should be rephrased to make it clear: simple minimax tree search is intractable because of the large branching factor, and that therefore more advanced techniques are needed. This way, the statement doesn't help perpetuate a belief that humans are fundamentally better or more insightful than computers in all domains. FalseAxiom (talk) 20:16, 28 September 2012 (UTC)[reply]
FalseAxiom is correct. Mscrhibr, your argument is a fallacy. More complex problems can be either easier or harder for computers to solve, depending on the specific domain. Quale (talk) 23:25, 28 September 2012 (UTC)[reply]
We are not comparing computers to humans. We are comparing game X to game Y. Game X such as chess has a state-space complexity of 10^47. Game Y such as shogi has a higher state-space complexity of 10^71. The computer is doing a lot more pruning at the shogi highest rated player level than at the chess highest rated player level. Therefore, it is harder for the computer to reach the shogi highest rated player level than the chess highest rated player level. The statement said, “Therefore, Shogi is the hardest of the popular chess variants in terms of programming a computer to beat the highest rated player”. --Mschribr (talk) 05:11, 30 September 2012 (UTC)[reply]
