4.5.1 Win by one (e.g. camel holding horse hostage)
5 Relative Values of Pieces
5.1 Importance of Elephants
5.2 Theories on Unbalanced Exchanges i.e M vs. HD, etc.
5.3 Impact of Piece Exchanges on value of rabbits
5.4 Quantity vs. Quality of Pieces in the Middlegame & Endgame

Just considering the table of contents has made me realize that I want to re-organize the basic strategy material. My understanding of the game has changed a good deal since the last overhaul of the Wikipedia "Arimaa strategy" article. I think I can get my thoughts in a better order than before. Moving existing content over to Wikibooks, and thinking in book/chapter/section format, will be a good excuse for me to do that overhaul.
I'm hoping you and others will write the new material on specific attacking and defensive strategies. That's vital information for anyone learning the game, but I tend to think too abstractly to write it well. I'm always looking for an über-strategy, and don't want to commit to anything specific, so if I wrote those chapters I would always be hemming and hawing, unwilling to commit to anything concrete.
I like the thought of many smaller pages. For example, the Arimaa Tactics article, which is currently a single page, should definitely be broken up into seven smaller pages as an invitation to expansion. I currently have a single diagram for "goal in one", but a manual for beginners should have more examples than that. Similarly for capture, and for capture defense, etc. We all know a lot about basic tactics from personal experience, a lot that isn't written down anywhere, and it would be good to go into more detail, if anyone cares to take on that task.
Other possible chapters to consider:
*Arimaa bots: general info relating to bot programming, possibly including a page detailing specifics about each bot
*Endgame strategies, insofar as we know anything about this
*Tactics related to strategic objectives (i.e. not just goal and capture, but trap control, hostage taking, framing, etc.)
Maybe there are yet other things folks would be willing to write chapters about. This is a big project, or could be, but I'll start chipping away at it, and hope that others chip in. Now that we have a diagramming tool it should be much easier to talk about strategy in a vivid way, with lots of examples, without having to resort to the GIMP for every new page or edit of an old page.
I'm excited to write more about Arimaa. I can say from experience that writing about the game forces me to think about it more clearly, and thus makes me a better player. Writing can teach you what you know and what you don't know, which is a great starting point for learning more. If you have anything to say about playing Arimaa, I highly recommend that you try to get it in writing, for your own good.

I can't wait to read the book; I'll definitely learn a few new things from it
Will it be possible to have various editions of the book? With Arimaa being in such a state of evolution it would be nice if we could preserve it's course of development. So for example we might have a different edition for each year. That way I could go back to the 2006 edition and see what was known about the strategies at the time.
If the wikibook site does not easily allow this. What I'd like to do is download a snapshot of the pages once a year and preserve them locally on the arimaa.com server. I don't think this violates their GNU FDL copyright.

That doesn't violate GNU FDL as long as your local version is explicitely placed under GNU FDL as well. I.e. it must be available under the same distribution terms as in the Wikipedia. Then it is absolutely fine.

We had better be careful when we create our book so as to avoid violating the Wiki rule on original research. As long as we are only annotating games in the database and not proposing theories that are untested in practice, will that be acceptable?
"primary research in any field — Wikibooks is not a place to publish primary research such as proposing theories and solutions, original ideas, defining terms, coining words, etc., and, as with other Wikimedia projects, maintains a strict "No original research" policy. If you have done primary research on a topic, publish your results in normal peer-reviewed journals, or elsewhere on the web, such as at Academia Wikicity. "

Thanks Paul.
I tried to make a local copy of the current Arimaa wikipedia pages so that we have a snap shot of it for future reference. I tried it using wget, but they disallow wget in their robots.txt file. Does anyone know of any other programs we can use to download the content under the .../wiki/Arimaa section. If someone is able to do it, please zip it up and send it to me so I can put it on the arimaa.com site.

I finally finished revamping the "Introduction to Strategy" section of the Arimaa Wikibook. http://en.wikibooks.org/wiki/Arimaa I think that folks who haven't read it yet will find it a bit more modern than what is on the Wikipedia.
Adanac has also contributed volumes of opening theory, which people should read if they haven't yet.
What we need next is a series of pages about specific types of mid-games, for example:
*Playing after a trade of M for HD
*Playing with a camel hostage.
*Playing with a horse frame.
*Playing when you have a horse hostage with your camel
Also we could use a generalized article about endgames. I suppose not much is known for sure about endgames, but it would be good to lay out what we suspect the general principles are.
Chessandgo, I know you have been contemplating writing more about Arimaa. Why not join our collaborative effort to make a book? All insights and styles of writing are welcome!

I’d like to do some extensive re-writes for the Wikibook but I’ve hit a bit of a roadblock. Here’s what I think needs to be updated/improved:
1. A new format for annotating games. I really like Chessandgo’s style of using BlackKnight’s game viewer to provide comments simultaneously with the moves. It’s much better than having a few diagrams here and there with scattered analysis or even a complete text annotation with a link to the moves on the arimaa website. I’ve halted my analysis of Paul Lefert – Frank Heinemann Postal Game (in the Dual Lone Elephant) until there’s an improved Wikibook system of annotation.
2. Re-write all of the individual sections for E+M Attacks/E+H Attacks, etc. - I find that there’s a lot of repetition. For example, there’s too much explanation that it’s best to place an elephant on d6 and supporting horse/camel on b6 or c7 in almost every chapter. It would be much better to have a single chapter devoted to high-level attacking concepts (balanced forces, elephant on d6, importance of a strong piece on b6, etc.) and then trim down the current chapters 6-12.
3. Similar to the previous point, I’d like to remove the setup sections from E+M/E+H/E+Minor Piece, etc. and just have a general chapter called about the setup. With current opening theory, it seems the only attack-specific chapter that would require its own section for setting up the pieces would be a blue22-style Double-Trap Attack.
4. Perhaps some new chapters for “Advanced Tactics” and “Advanced Strategy” – the latter could be devoted to full-board strategic ideas. I think that the key to understanding Arimaa is not to study E+M attacks in gruesome detail but to just understand the high-level idea that the silver camel will be unopposed on the east wing if the gold camel is held hostage on the west wing. I’m not sure whether these should precede or follow our current chapters 6-12.
5. What happened to chapters “1. Overview” & “2. Playing the Game”?? Didn’t we already create these sections?
6. I like Fritzlein’s idea for an endgame chapter, but that may be the most difficult chapter of them all to create! Who’s feeling ambitious?
7. Is Omar planning to convert the move notation to be consistent with the colour of the pieces? I’ve never believed it was consistent to label the moves 1w 1b 2w 2b 3w 3b if we’re using gold and silver pieces. I’ve been using a 1g 1s 2g 2s convention in the Wikibook but I do want to ensure that the style is consistent throughout. I’ve thought of switching my notation to white & black, but then that’s a lot of unnecessary work if we’re eventually going to switch back to gold & silver. Another consistency issue: as I edit my sections I’ll switch the piece names to lower case. I had been using “Gold Elephant” rather than “gold elephant”, but I’ll switch over to be consistent with everyone else.
8. In order to simply concepts such as E+H Attack, I always assumed a gold attack against c6 for the illustration. That way I could say "the gold elephant belongs on d6" rather than "the attacking elephant belong on the sixth rank between the two enemy traps". Previously each chapter had contained a bold disclaimer that the ideas described apply equally to every trap, but now that we're creating sub-chapters, we may need to place disclaimers in every sub-chapter too!

Maybe we could brainstorm some general principles for the endgame and then write up a chapter.
- Piece mobility becomes increasingly important during the endgame, especially rabbit mobility.
- Endgames should be played very aggressively.
- If there is active play on both wings then goal threats and initiative are far more important than material.
- Advanced rabbits on both wings are a nightmare to defend against. If the opponent has 1 rabbit on the west wing and 4 rabbits on the east wing, the west wing rabbit is far more valuable than any individual east wing rabbit.
- Corner rabbits (a1, h1, a8, h8 ) are extremely valuable defenders against advanced enemy rabbits. Obviously this won't apply in all situations (e.g. a rabbit advance up the middle) but would everyone agree that the corner squares are more important as a general rule than b1-g1, b8-g8? Perhaps too hypothetical to include in the “facts only” Wikibook anyway.
- The “Relative Value of Pieces” section covers this already, but I suppose it wouldn’t hurt to mention again that rabbits become increasingly important during the endgame. But as Ryan proved against me, they don’t necessarily become *more* valuable than dogs and horses!! 
- Elephants should always remain centralized unless crucial for a goal attack/defence.
- Rabbit frames are more dangerous on a depleted board. For example:
Gold: Ra6 Rb5 Mc2 Cb3 Ed6
Silver: ra8 ra7 rb8 rc7 hb6 da5
Silver should not spend 4 steps to a frame a nicely blockaded rabbit, regardless of what the board looks like on the east wing – especially since the west-wing rabbits may have better goal prospects if shifted towards the middle of the board
- We could describe tricks such as pushing/pulling enemy rabbits onto their 2nd rank and keeping a clear space next to the corner. Example with silver to move:
Gold: Ra7 Ca6 Ec8
Silver: ra8 rb7 rc7 rd7 cb6
Hmmm, maybe that’s more of a middle-game trick than an endgame one.

What do you suggest? BlackKnight's game viewer is obviously the best place to put commentary, since it can handle variations, but it won't have the exposure and permanance of Wikibooks.
If we do put annotated games into Wikibooks, then a diagram for every comment seems essential. If we don't diagram every comment, then I feel we might as well not have any annotated games in Wikibooks, and rather put everything into BlackKnight's game viewer.
Quote:| 2. Re-write all of the individual sections for E+M Attacks/E+H Attacks, etc. - I find that there’s a lot of repetition. |

I agree. It would be much easier to digest if you broke out a bunch of the common information into an Opening Theory page, and had briefer pages about information specific to each opening.
Quote:| 3. Similar to the previous point, I’d like to remove the setup sections from E+M/E+H/E+Minor Piece, etc. and just have a general chapter called about the setup. |
|
Agreed. There needs to be more about the setup than my dinky subpage in Introduction to Strategy, but it seems logical to me to collect various ideas in one place, after a discussion of general opening theory.
Quote:| 4. Perhaps some new chapters for “Advanced Tactics” and “Advanced Strategy” – the latter could be devoted to full-board strategic ideas. |
|
I definitely agree. Not only do there need to be deeper examples of forced goal and forced material win, there need to be tactical examples about attaining strategic objectives, e.g. "Gold to move and ensure an elephant blockade" or "Silver to move and insure a horse frame"
Quote:| I think that the key to understanding Arimaa is not to study E+M attacks in gruesome detail but to just understand the high-level idea that the silver camel will be unopposed on the east wing if the gold camel is held hostage on the west wing. |
|
I sort of agree. I think that advanced strategy requires understanding certain types of positions in gruesome detail, especially camel-hostage positions. I stand by my suggestion of themed mid-game positions as a basis for advanced strategy, and I suggest they come before the opening theory section. You can't really discuss an E+M opening attack very clearly without knowing when a camel-hostage is terrible, acceptable, or even advantageous to the hostage-giver.

I like all the ideas you presented for the endgame page. There's no specific treatment of goal attack and goal defense yet, and an endgame section seems like a logical place for that discussion to go. You're probably better equipped to write an endgame page than I am, but I might take it as a project if you are busy re-organizing your other pages. The one idea I would add is that having a piece (even a mere cat) directly in front of an advanced rabbit gives one many more defensive options than blocking a rabbit with a rabbit does.

I tried it your way for a bit, and found that I liked lower case piece names better. Too much upper case seemed distracting rather than clarifying.
On the other hand, I do like to use capital "Gold" as a convenient abbreviation for "the player controlling the gold pieces". I've gotten so used to it that even "the gold player" seems too long. I try to consisently use lower case for "gold" as an adjective, e.g. "the gold elephant", so that when upper case "Gold" appears it is a tipoff that I'm talking about a person, e.g. "all that Gold can do now is push rabbits."
IMHO this capitalization is a good way to be clear and brief, but I'm open to alternatives.

I copied the rules over from Wikipedia into the "Playing the Game" page, and created an "Overview" page based on other Wiki material. The former still needs to be edited to fit the purpose of the Wikibook (rather than The Wikipedia) and the latter is very rough, because I can't think what all belongs in an overview.

Okay, once I catch up on all my postal games and play a few of our 45s tournament games, I'll try to devote a couple of hours per day to the Wikibook. I believe we now have 21 chapters, with most of them requiring considerable work.  Actually, I am looking forward to cleaning up the mess and creating a readable, informative, diagram-filled Wikibook.
1. Overview -> needs considerable re-write
2. Playing the Game -> edit to fit the purpose of Wikibook
3. Introduction to Tactics
4. Introduction to Strategy
5. Relative Value of Pieces
6. Opening Theory -> needs to be created -> will include setup & ideas leading into the 8 attack-specific chapters below
7. Positioning for an Attack -> probably needs a better title -> Will replace repetitive information in the following chapters
8. Advanced Tactics -> needs to be created -> ideas for the intermediate player; not for beginners -> should have a disclaimer that the reader should play several games before reading this chapter
9. Advanced Strategy -> needs to be created -> same disclaimers as Advanced Tactics
These 8 chapters need to be re-written to remove redundancies, edited to reflect newly discovered theories and expanded with more diagrams
10. Lone Elephant Attacks
11. Elephant and Camel Attacks
12. Elephant and Horse Attacks
13. Elephant and Minor Piece Attacks
14. Multi-Piece Swarming Attacks
15. Camel and Horse Attacks
16. Double-Trap Attacks
17. Other Attacking Ideas
18. Endgame Theory -> needs to be created
19. Arimaa Challenge History
20. Sample Games
21.Glossary
