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

* 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.
Sadly its come to an end. But I might put the bishop and knight checkmate teaching section into algebraic notation. Bernard Freedman's method has great merit.
The black king seems to have the whole field and ready to escape away from thw black corner; but Be3 prevents this. The B, N, and K should act toward the black king like a shepherd and his dog herding his sheep slowly and surely into the enclosure. Hardly any checking.
1.Be3, Kf7 2.Bd4, Ke8 3.Ke6 Kd8 4.Bb6+ Ke8 5. Nf5 (very important key move No.1) , Kf8 6.Bd8, Ke8 7.Bg5, Kf8 8.Be7+, Kg8 (if Ke8 mate next move) 9.Kf6, Kh8 10.Kf7, Kh7 The knight is doing a job of controlling the h6 square so before releasing the knight, White plays Bf8. The bishop will do the same job of covering the h6 square.
11.Bf8, Kh8 12.Ne7, Kh7 13.Nd5, Kh8 14.Bg7+, Kh7 15.Nf6 checkmate.
We know now that with a bishop covering the black squares we have to mate in one of the corners which has a black square.
Black Ka8 (white square) White Pieces Kc6, Bf2, Nh3 or anywhere on the board. We are systematically going to cover with the knight and bishop the square at a8 - b8 - c8 - d8. Black is going to try to escape towards the white corner.
1.Nf4, Kb8 2.Ne6, Ka8 3.Nc7+, Kb8 4.Be3 (tempo), Kc8 5.Ba7, Kd8 6.Nd5 (very important key move No.1), Kc8 (if black K-e8 instead of Kc8, White Kd6 followed by Ne7 see "Intermediate Position") 7.Ne7+, Kd8 8.Kd6, Ke8 9.Ke6, Kd8 10.Bb6+, Ke8 11.Nf5 (very important key move No.2), Kf8 12.Bd8, Ke8 13.Bg5, Kf8 14.Be7+, Kg8 15.Kf6, Kh7 16.Kf7, Kh8 17.Bf8, Kh7 18.Ne7, Kh8 19.Nd5, Kh7 20.Nf6+, Kh8 21.Bg7 checkmate.
1.Bb2, Ke7 2.Nd2, Ke6 3.Kf2, Kd5 4.Kg3, Kc5 5.Bc3 White controls the whole fourth row with his three pieces (except a4). The black king can never pass. White moves his king up to close in on the black king, White has plenty of tempo moves. Black will have less and less. If White can repeat a similar position on the fourth or fifth row, it will be very easy to force the black king in any corner or back row. With the black K at a1 instead of h8 and white pieces Bc1, Kc2, just imagine the board turned around. With the white bishop on a white square (instead of a black square), you mate on the white corner square instead of the black corner square.
You can also close in on the black king from both sides of the final corner. Try the above position on every corner of the board forcing the black king to the corner from both sides.
