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.
In the past a few players participated with eye movement research at the University of Toronto. The first article is published. The Mechanisms and Boundary Conditions of the Einstellung Effect in Chess: Evidence from Eye Movements.
If you want to read the article, there's open access.
Re: Results eye movement study: einstellung effect
I took part in a study in the late 90's perhaps early 2000 at U of T and recall it had something to to with vision testing and chess. Is this the right time frame for the data collected for this study?
Re: Results eye movement study: einstellung effect
Thanks for providing the link. A fascinating finding. I for one am going to consider more carefully non-obvious solutions when analysing "obvious" solutions based on whatever patterns I have stored.

Re: Results eye movement study: einstellung effect
Hi,
@Larry: No problem!
@Bill: John is right. Data collection was a few years ago.
@Tom: Maybe you like the quote from Lasker: "When you see a good move, look for a better one.”
Did they consider any basic RPvR endings where the focal line was divided nearly in half (some that are draws on a Bishop or Rook file might be a win on a centre or knight file - or the puzzle could be: which choices of hilighted squares would you optimally place a defending King, in general, knowing an array of an army, but not a file location)?
Is it worthwhile to consider a puzzle that an IM or GM might get more often on a scale graded by day-of-week difficulty (ie www.chessgames.com tries to do this regularly, but this morning, they repeated last Monday's puzzle, where this week's task seemed more to identify the players in a deja-vu problem)? Maybe something like http://www.chessgames.com/perl/chessgame?gid=1029363 - move 45.?
What about for puzzles where the board is not partially or fully blocked? Or sharp (ie where only 1 move holds a win, 1 or 2 draw, but the rest fail miserably to a tactical defense), instead of more quiet positions?
Would any sorts of board division lines in those types of draw puzzle have thrown anyone off (and is it partially related to their claimed effect(s))?
---
Did any of the participants ask to look at the puzzles from a DGT board perspective, instead of looking at a screen (one might presume that they could still track the eye motion)? Does anyone look at separate sectors of the board separately at coffee-table or standing overhead level than at regular table-height sitting level, or looking at the position from the other side if the board or other side?!
I didn't participate in the study, but might consider my vision and chess skills at about the average level ranked in a general population.
