**Clubs:** Thank you to GM Thorsten Michael Haub @DJ_Haubi for the invitation to join The Great Viking Warriors! This is a very strong private club that works hard to promote fair play.

**Chess:** I have played in numerous USCF over the board tournaments. Now I mainly focus on daily games of standard chess and chess960, as well as promoting fair play in daily chess. My goal is to become a USCF Candidate Master in correspondence chess.

**Games**

White was played by FIDE Master Marco Ferrante (FIDE Rating 2333) and I played black. White offered a draw after move 20.

Sicilian Defense: Open, Najdorf, Poisoned Pawn Variation Accepted

There are 3 moves I want to highlight.

- White played
**16. Rd1**, which is by far the most popular move in the chess.com master game database, and a good move according to the computer analysis. The only other move in the database is**16. Nxf6+**, which the computer analysis claims is the best move. - Black played
**18… Ra7?**, which is the most popular move in the database by a slim margin, but the computer analysis calls the move a mistake (not an inaccuracy). The only other move in the database is**18… f5**, which the computer analysis claims is the best move. - White played
**19. Rf3**, which is the most popular move in the database by a slim margin, and a good move according to the computer analysis. The only other move in the database is**19. Qh6**, which the computer analysis claims is the best move.

If I could propose a new time control for daily chess, it would look like this.

- Start with 3 days on the clock.
- After each move, carry over unused time and add 3 additional days.
- Have a cap so that a player cannot use any more than 10 days on a single move unless they use vacation time, although they still keep all unused time even if it is more than 10 days.

**#9 The Weirdest World Championship**from**10 Craziest Events In The History Of Chess**. The event was the 1978 World Chess Championship between Anatoly Karpov and Viktor Korchnoi.*“Korchnoi was also bothered by a member of the Soviet entourage named Vladimir Zukhar, a parapsychologist who would sit in the front row and stare malevolently at him. Korchnoi suspected that Zukhar was hypnotizing him and interfering with his brain waves. Thanks to the “psychic,” Korchnoi was a nervous wreck by the seventh game.”*
