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
* Harassment
* Adult content
* Obscene material
* 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.
Here is a sample of the quality of composition produced by Steve Laughlin of Toronto. Steve has finished another book that I will convert to a PDF file complete with full colour coded solutions. Contact me for more info.
White to play and win. Hint: Fritz has a lot of problem with this one (it's too deep)
For me, my solution is too long.
1 Kd2 Kb2
2 Qa1 Ka1 (still need to find something good for Kb3!? Qc3 Kc2...)
3 Kc1 and trying to mate with Ke1-c2X, but some variations go upto moving the h4 pawn to h8 Qx :)
Without thoroughly analyzing the postion, the theme seems to be to stalemate the Black K, and mate it with the N - e.g.
start with 1. Kd2+ Kb2 2. Qxa1+ Kxa1 3. Kc1 Bh7 (to stop Ne1-c2 mate) 4. Ne1 Bxd3 5. Nxd3 Ra anywhere (if Rb5, take it). Ne1, followed by Nc2 mate. Am I missing anything?

Nc2 mate can be avoided :D
Ra not anywhere but Ra4 Ne1 and Rc4+ Nc2+ (not mate!!!) and then goes my idea with h8Q (again not mate!!!) as Black pushes a pawn to c3 (where it is blocked but blocks check as well). Thus final move with mate Qc3x :) Here could be B as well spoiling the solution (?)
Solution confirmed with Rybka 2.2n2. Fritz 11 have not found...
Yes, but I think you should mention the continuation after 1. Kd2+ Kb2 2. Qxa1+ Kxa1 3. Kc1 Bh7 (to stop Ne1-c2 mate) 4. Ne1 Bxd3 5. Nxd3.........5....Rxa4 with the idea to give up the Rook for the Knight. 6.Ne1 Rxc4+ 7.Nc2+ Rxc2+
The remainder is the funny part.
Still I give you 9.5/10 ....deduction for form.
Your comment about the under promotion is alert. I don't think studies are flawed by such things. If I posted the diagram as a Mate in 15! everything would be spoiled.

That why I putted a question mark (?) The move is not a final one.
P.S.
Fritz 11 still searching (~20min) vs 1 min with Rybka :)
