General Guidelines

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.
My post clearly implied that I didn't think cheating was likely, so I don't think it's defamatory. Even looking at the game with Preotu, Black is clearly a strong player, but his play doesn't come across as computer-like.
When I was coming up I played maybe 100 tournament games a year, at 3 hours a game, that's 300 hours of practice, and assuming a good amount of studying, analysing chess with friends, or playing blitz, that's maybe 1000 hours a year. Online play wasn't really a thing at the time. Today it would be incredibly easy to devote double that time to chess through online play, also the available training materials are MUCH better than they were.
Will we ever see a world championship candidate develop out of purely online play? Maybe it's only a matter of time.
Looks like a two-way tie at the top, in the Open, at 5.5/6, with GM Paragua and IM Rodrigue-Lemieux, so they should probably meet next round. But will it be on board one!? Smart betting money says 'NO!!' Many other strong players remain in contention in what is shaping up to be a fascinating conclusion over the weekend!!!
3 on top
IM Shawn Rodrigue-Lemieux (5.5) will defeat GM Mark Paragua (4.5)
IM Nikolay Noritsyn (5.5) over Ryan Campbell (5.0)
GM Joshua Sheng (5.5) over FM Eugene Hua (4)
IM Olivier-Kenta Chiku-Ratte (5) combo finishes off GM Isan Ortiz (4.5)
and maybe half of the 14 others who had 4 points could now have 5.

I think it might be just SRL alone in 1st with 6.5/7 --- with Noritsyn, Sheng and OKCR tied for 2nd with 6 {but I'm just kind of guessing using round 5 totals and results on top boards today} I'm thinking the standings will be posted within the hour.

I was not talking about your post. I was talking about an earlier one which has been edited with the defamatory material deleted.
I think we are headed for a future where a large percentage of our new members will come from the online world.
Impressive showing by Gavrilin (2235). He has drawn with GM Mikhalevski (ISR), drawn with GM Hambleton (CAN), drawn with IM Banerjee (IND), and defeated IM Zhang (CAN). In round 8 he faces GM Ortiz of Cuba. Not sure if a norm is possible, since his other three games were with players of ratings 1891, 2020 and 1545 (all wins). That might be too many low-rated and untitled players for norm qualification. In any case, a noteworthy performance!!
I have to say I admire the play of Shawn Rodrigue - Lemieux in rds 6, 7, and 8. In rds 6 and 7 he made it look smooth which it definitely is not and converted in the endgame. In rd 8 he uncharacteristically started interesting tactics from the opening but I enjoyed that nonetheless.
Shawn Rodrigue - Lemieux and Nikolay Noritsyn have set a torrid pace with 7 out of 8 and are tied for first ahead of all the 12 grandmasters. Impressive!
RE: Ryan Campbell
I was suspicious too. Who beats an FM, then beats a GM... and then allows a mate-in-one in his next game??
Good reason to be suspicious, IMO.
But: Today I talked with the organizers -- Aris, Hal, Omar, Patrick -- and it is clear to me that they have done everything (short of a body-cavity search) to verify that Ryan Campbell is NOT cheating. They even had Ken Regan, the world-leading-expert in computer-analysis-based cheating detection, go over Ryan's games, and Ken's analysis found nothing suspicious. Therefore, please:
1) do not post malicious s**t about Ryan Cambbell.
2) do not post malicious s**t that implies that the TDs and Organizers of the 2022 Canadian Open are incompetent boobs.
PS: Ken Regan was there today, and I was very happy to have a chance to learn more about his work. Here's a cool tidbit: Ken had already analyzed Alireza's 250 game "bullet marathon" against GM Daniel Naroditsky that they played online between rounds during the 2022 Candidates. One point of this was to test the extent to which 2800+ players' moves decline in quality as their thinking time shortens. Interestingly, both Alireza and Hikaru show almost the identical decline in their accuracy as every other chess player!? Yes, they play better; but at short time controls they decline at the same rate and degree as the rest of us ordinary mortals.

Good find, Frank.
To get a norm requires a few variables. First, have to play 5 titled players. Only Noritsyn and Rodrigue-Lemieux have played 5 titled players, but for a score of 7-2 needed an average opponent rating of at least 2380 for a GM norm (Rodrigue-Lemieux has 2367 Noritysn has 2327, big assumption that all ratings are FIDE, not CFC). But a score of 8-1 is .88 so add 336 and either one could get an over 2600 norm. A draw is .83 so add 273 (2640 or 2600). They have only 3 or 2 foreign opponents and over the max 5 from Canada, but these requirements doesn't apply as there are over 20 foreign players (10 masters) in the Swiss.
Roman Gavrilin scored 1.5-2.5 against titled players but doesn't play a titled player in the last round. He plays child star Aaron Mendes who has 2-2 against titled players.
Both Joshua Terry and Ryan Campbell scored 2-3 against titled players. Neil Doknjas scored 1.5-2.5 against titled players.
The game Chiku-Ratté - Noritsyn just finished draw. An interesting (and paradoxal) try for black is 51...Rh4 with the idea 52...Rf4 or f4+ if the white rook quit the 5th rank. On 52. Rxf5+ Kxf5 53. Kxh4 Kf4! 54. Kh5 e3 win for black. Nice save by Olivier-Kenta!
Also nice save by Shawn against GM Sambuev. White have a lot of winning continuation, the fastest is 73. Kd4, but the ending with Q + b (after 73...Qd7+ and 74...Qxa4) or g pawn against Q is one of the tougest to win and one of the toughest to defend. Before checking with syzygy endgame tablebases, my idea was to not take the pawn with 71. Ka5!? bxa4 72. Qc4+ Kf8 73. b5 seem to win.

A very competitive event. Nice to see Canadians winning the Canadian Open :)
Congrats to Shawn and Nikolay!
Shawn went from the CYCC to the Canadian Open...and tomorrow he will be the star at a week long chess camp for kids in Montreal, run by the Chess'n Math Association! He will be going out with the kids in the morning playing soccer etc and then the afternoons will be all about chess.
There are a few places left. You can send an e-mail to Virginie Roux: montreal@chess-math.org or give her a call tomorrow morning after 8:15 am...514-845-8352.

Since I am the person in the CFC that most alleged cheating cases reach, I was asked to look at the first five games of Ryan Campbell. I did so. My conclusions delivered on the evening following the fifth round were that there was no indication of foul play, that play was not perfect but it was a delight to analyze the games. In a couple of the games I had the help of my roommate and former student (about to be IM) Rohan Talukdar who pointed out that Ryan employed some very subtle move order tricks in the opening to push his opponents into unfamiliar territory. The net result of this was that one opponent was playing the accelerated Dragon instead of the more familiar Najdorf Sicilian. Rohan said that this was a sign of deep thinking as he (Rohan) had experienced the same move order tricks in some of his games with grandmasters.
Engines do not typically employ such tricks because they don't care whether the game is an accelerated Dragon or a Najdorf Sicilian. It is all just pure calculation to them in either case.
The game against the 1900 player should have ended in a draw as Ryan allowed an exchange sacrifice which should have led to a perpetual check. The opponent made a mistake on move 121 or so which allowed promotion of a pawn and ended the series of checks.
This Ryan Campbell situation was a feel good story of the tournament. Sometimes lightening does strike and a player goes on a run based on a combination of luck and skill.
In a tournament of this size it is expected to happen to at least one or two players. We should not be surprised when it does happen.
Dr. Ken Regan is doing a great deal of fascinating work on chess and chess performance using statistics and his proprietary models. It was fascinating to watch how quickly he could change parameters of his explorations of the data and watch him type in the queries needed to get the answers he wanted. I could have listened to him for twelve hours straight despite being a tad exhausted at that point in the tournament due to the issues with the Chennai Olympiad and Congress and the week of sleeping in an unfamiliar bed. That was just one of many highlights of the tournament which made the whole experience worthwhile.
Thanks for your comments Vlad. It was good to see you playing, and playing well! I share your apprehension about Chennai - hot, sticky and crowded if one manages to score a visa in the first place. I hope we all get there and back!
