General Guidelines
---- Nous avons besoin d'un traduction français!
Some Basics
1. Under Board "Frequently Asked Questions" (FAQs) there are 3 sections dealing with General Forum Usage, User Profile Features, and Reading and Posting Messages. These deal with everything from Avatars to Your Notifications. Most general technical questions are covered there. Here is a link to the FAQs. https://forum.chesstalk.com/help
2. Consider using the SEARCH button if you are looking for information. You may find your question has already been answered in a previous thread.
3. If you've looked for an answer to a question, and not found one, then you should consider asking your question in a new thread. For example, there have already been questions and discussion regarding: how to do chess diagrams (FENs); crosstables that line up properly; and the numerous little “glitches” that every new site will have.
4. Read pinned or sticky threads, like this one, if they look important. This applies especially to newcomers.
5. Read the thread you're posting in before you post. There are a variety of ways to look at a thread. These are covered under “Display Modes”.
6. Thread titles: please provide some details in your thread title. This is useful for a number of reasons. It helps ChessTalk members to quickly skim the threads. It prevents duplication of threads. And so on.
7. Unnecessary thread proliferation (e.g., deliberately creating a new thread that duplicates existing discussion) is discouraged. Look to see if a thread on your topic may have already been started and, if so, consider adding your contribution to the pre-existing thread. However, starting new threads to explore side-issues that are not relevant to the original subject is strongly encouraged. A single thread on the Canadian Open, with hundreds of posts on multiple sub-topics, is no better than a dozen threads on the Open covering only a few topics. Use your good judgment when starting a new thread.
8. If and/or when sub-forums are created, please make sure to create threads in the proper place.
Debate
9. Give an opinion and back it up with a reason. Throwaway comments such as "Game X pwnz because my friend and I think so!" could be considered pointless at best, and inflammatory at worst.
10. Try to give your own opinions, not simply those copied and pasted from reviews or opinions of your friends.
Unacceptable behavior and warnings
11. In registering here at ChessTalk please note that the same or similar rules apply here as applied at the previous Boardhost message board. In particular, the following content is not permitted to appear in any messages:
* Racism
* Hatred

* Nudity or pornography
* Material that infringes intellectual property or other proprietary rights of any party
* Material the posting of which is tortious or violates a contractual or fiduciary obligation you or we owe to another party
* Piracy, hacking, viruses, worms, or warez
* Spam
* Any illegal content
* unapproved Commercial banner advertisements or revenue-generating links
* Any link to or any images from a site containing any material outlined in these restrictions
* Any material deemed offensive or inappropriate by the Board staff
12. Users are welcome to challenge other points of view and opinions, but should do so respectfully. Personal attacks on others will not be tolerated. Posts and threads with unacceptable content can be closed or deleted altogether. Furthermore, a range of sanctions are possible - from a simple warning to a temporary or even a permanent banning from ChessTalk.
Helping to Moderate
13. 'Report' links (an exclamation mark inside a triangle) can be found in many places throughout the board. These links allow users to alert the board staff to anything which is offensive, objectionable or illegal. Please consider using this feature if the need arises.
Advice for free
14. You should exercise the same caution with Private Messages as you would with any public posting.
I just came across a game with the classic Rxb2 (or Rxb7) followed by 0-0-0+ winning the R. The annotator(s) in this game never saw it. Check the position at White's 20th move. (this annotated game was published in the Oct. 1991 issue of "En Passant". Johanne was Canada's rep in this event - Alexandre Lesiege was in the concurrent men's event). I think this type of position is as rare as quadrupled P's.
With White to move on move 20, the R is still unprotected (Black hasn't played ...e4 yet). And the Fritz evaluation suddenly goes from +0.41 to +3.00.
I wonder if both the White player and the annotator thought that 0-0-0 wasn't playable because the White Rook isn't allowed to cross over a square that is under attack by a Black piece (the Black Rook)?
I actually thought this was the rule for Queenside castling, but looks like I was wr... I was wooo.... geez, I'm acting like Jean Hebert... I was WRONG.
Only the rushing is heard...
Onward flies the bird.
I played Rxb7 against Yan Teplitsky, and he instantly played O-O-O, threatening mate at d1. 0-1. I don't feel bad about overlooking the tactic, my crucial mistake was earlier. The line culminating in loss of the rook (or mate) was a desperate one, everything else was hopeless against a player of Yan's class.
That effort was pretty close to O-O-O+. I'm still working on quadrupled pawns. Too.
There's a story about Kortchnoi, decades ago, needing to ask the arbiter whether castling was legal in such a position.

The famous game was played during the 1974 Candidates Match (m/21):
[Event "Moscow"]
[Site "Moscow"]
[Date "1974.??.??"]
[EventDate "?"]
[Round "21"]
[Result "1-0"]
[White "Viktor Korchnoi"]
[Black "Anatoli Karpov"]
[ECO "E17"]
After 17...Bxd5: "At this point I went up to the controller, and asked whether it was legal for me to castle when my rook was attacked. I was assured that it was. Afterwards, this incident was cited as being an indication of how extremely tired the players were. But in fact, out of the two and a half thousand games that I have played, there had never been an instance where it had been necessary for me to castle when my rook was attacked, and I was not sure that I understood correctly the rules of the game!" Korchnoi in Chess is My Life (first edition).
Gilles also questioned if it was a real game. As Jean Hébert pointed out, it certainly is. It was game 46 in the original edition of The King-Hunt by William Cozens (Bell 1970).
Unfortunately, the player of the black pieces is given only as Laurence. Sadly, when John Nunn put out a revised, algebraic version (Batsford 1996), he didn't correct the error.
There was a book written by FM Robert Timmer called Castling to Win! (ICE 1997); a translation of the 1994 Dutch work. Chapter 3 is entitled "Queenside Castling after a Rook Capture on b2 or b7". It contains 20 games and fragments on the theme.
