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

* 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

* 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.
Another exciting game. This time with black against a solid 2450+ IM. For most of the game I had to defend against a very dangerous attack. After a timely counter-blow I was able to reach an endgame with a B + 5 against a B + 4. I think it should be winning although I wasn't able to. I would like to know what The computer says.
I left Fritz running on it overnight. It thinks Black *can* win... I don't have the endgame tablebases installed though, and without those it can be a little weak on endings since a human can in some cases go deeper than the computer will.
I don't know if you need Rybka, but rather Rybinstein.
ECE does not have your ending. The closest I could find was 4 v 3 (all pawns on one side and no inroads), four examples in NB 7/g. Three were won, and the other (Ingrid Dahl vs. Agnieszka Brustman, Slupsk 1987) was drawn. The wins were Szabo - Westerinen, Leningrad 1967; Beljavskij - Rogulj, USSR vs Yugoslavia 1977; and a study by Beljavskij and Mikhalchishin dated 1992. That pair also did the analysis of the female game.
One guy who can play bishop endgames all week is Spraggett. Heck, he doesn't even need the pawn up, if the opponent has a bad bishop. But all pawns on the same side makes the challenge different.
In most endgames where 4 vs 3 is good, 5 vs 4 is better. I guess most famously with rooks. But with bishops the hurdle is often the inroad, i.e., getting the king in to attack the opponent's pawns. No inroad = no win.
I'd certainly have played that position to be a win. If it is not, you have my heartfelt condolences.

Right. Basically you need to create a passed pawn with your king in front of it, or well advanced, and even that doesn't ensure a win. (at least I think that's the try.) I don't think this is an easy ending because white doesn't have an isolated pawn.
Still, the chances are all with black and he can cause white lots of aggrevation. It's white who has to eat the time on the clock if black has a plan. So I'd have played on. Often after another 10 or 15 moves the position and chances take on a different perspective.
If a computer will solve this position, I will have to be the computer on a players shoulders.
Both Ron and Leonid drew in the 10th (Leonid found Castaño too tough a nut to crack :D) and have 6.5 points going into the last round. I think that 8 will be required to qualify, if so they're out of the running, but they've represented Canada well. Congratulations!
The good news is ... they don't play against each other!
What a thought! Ron implied that he played on from the given position. He just wasn't able to win it, is all.
That's nice to hear. I didn't see the entire game, only the posted position. Maybe Ron will post the entire game for end game buffs to pore over. If someone could find a win it would certainly be instructive.
