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.
15. Have fun!

World Championship 2021 match will start Nov. 24!!
Game 6, at 136 moves, may be the longest decisive game, and perhaps also the longest overall game, in a World title match. Black, in the ending of R+N vs Q, had the type of position which is very hard to hold against super opposition; it is so hard to find a plan for Black; wonderfully played by the champion!
Two previous very long games, both drawn: Tal vs Botvinnik, 1961; and Korchnoi vs Karpov, 1978; both in the 120-move range.
In the commentary by Judit Polgar and Surya Ganguly (?) I believe it was mentioned when there were only 7 pieces left on the board (Black K+Q; White K+R+N+P P) the position was a tablebase draw.... with the usual caveat 'with best play'. That last part proved to be Nepo's undoing - lost of places for Black to lose the thread of the defense whereas White slowly grinds ahead. That sounds like a description of many of Magnus' games! Amazing stamina by Magnus (and the commentators too!) over nearly 8 full hours of play.
Brilliant game by Magnus. The queen was a mere spectator at the end. Lots of hard work, stress, and mental duress in the last 60 moves of the game (from Rxf7+!) and Magnus was short of time too. A game to talk about for a long time. (its one thing for computer evals and entirely another to play it over the board). Fantastic, awe - inspiring performance!
Very tight match up to now. Nepo is playing very well but he's playing against an extraordinary human. Only +1 for Magnus, the match is by no means finished, And Nepo has difficulties with Magnus secret weapon the Marshall. Imagine that gambit is more than a hundred years and is still a very valid opening. Amazing what an invention by Frank Marshall. Of course Nepo is playing some anti- Marshall, but still it shows rhe well deserved reputation of the Marshall gambit.
Magnus' move order might be a psychology ploy (The threat is stronger ...), Black is not obliged to play the Marshall after 8.c3 but instead can return to the other mainlines after 8...d6.
I think game 6 will be recognized as one of the greatest of all time. It had a bit of everything!! Perhaps Black can draw with perfect play; not attainable at the board in this instance with fast time controls and no adjournments. I think a player such as Paul Keres could perhaps have drawn with Black given the chance to adjourn and resume.
The Marshall Gambit was kept under wraps by Frank Marshall (1877-1944) for a decade, before he unveiled it for the first time against J. R. Capablanca (1888-1942), at New York 1918. He had played the Petroff (Russian) resolutely against 1.e4, during that period. As it turned out, Capa won the game!! He became World Champion 1921-1927. Marshall was U.S. champion at the time (1909-1936). But Capa, a Cuban who was not eligible for the U.S. title, had thrashed him in an unofficial match in 1909, not quite ten years before the Marshall Gambit made its first appearance.
GM Boris Spassky likewise essayed the Marshall as his main weapon against 1.e4 in his 1965 Candidates' final match against GM Mikhail Tal. GM Spassky won the match.
I tried out an interesting anti-Marshall variation against Kingston's Geoff McKay (2000+ player, many-time Kingston champion, who was a Marshall aficionado) in a number of friendly games a few years ago. In four games with the variation, I won two and drew two. I haven't seen it played elsewhere.
The line goes:
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 O-O 8.Na3!?, and now 8...d5 (the Marshall themed move) 9.exd5 Nxd5 10.c4!?
Now, if 10...bxc4 11.Nxc4; if 10...b4 11.Nc2.; I think White has a good position in either case, and there is a lot of energy still on the board with some imbalance. Of course, there are other possibilities. NM Christopher Pace declined the idea with 8...d6, reverting to more normal play in the Closed variations, when I tried it against him in a 2017 friendly game at quick time controls at the Kingston Chess Club. Although White's N/a3 looks on a limb, I got a good game and managed to win, for one of my very few times against Chris!
Olimpiu Urcan on Twitter: This epic Magnus Carlsen versus Ian Nepomniachtchi game lasted longer than the whole 7 episodes of "The Queen's Gambit" mini-series on Netflix.
Rd 8 Nepo is playing shaky moves. Is b5 a blunder? Looks like he overlooked Qa3+. Even with the computer evaluations saying + 1.5 for White, if you do some basic analysis you find he will be down a pawn, his king is not safe and White's pieces are more active. Not good.
Headed into a queen and pawn endgame with Nepo trying to save it but White is two pawns up and the computer says +5.

Magnus won relatively easily today in a Petroff defense from Nepo. He played 3 d4 which is recommended by Wesley So and Anish Giri in their Chessable courses. 3 d4 is not the main move but is the highest scoring move in my database. Nepo had a small minus throughout and played the bad move b5 as Hans noted. Magnus takes a commanding lead with only 6 game remaining.
Nepo should have played 10 Qe7 after 10 Qe1 + and Magnus would have had only a small advantage. Probably Nepo wanted a more complex game but it became complex only for him as Magnus' edge was increasing a lot.
Nepo must open the machine (anyway that's what he does most of the time) and play the Grunfeld or Najdorf but Magnus will play it very safe. Maybe 3 Bb5 + against the Sicilian which Magnus plays often and with success. And against the Grunfeld enters some endgames lines which are slightly in white's favor. Nepo is in a very bad situation. His odds of winning this match are now very slim in my opinion.
