   Jul-29-21 Karjakin vs Shankland, 2021 (replies)
DirkMcCallahan: The position after 26...a3 makes for a nice puzzle. At the time, Short seemed pretty convinced that 27. Qh6 was a winning move.

DirkMcCallahan: Sorry for referring to an old post, but re: the 2018 Candidates Tournament Simulation, might I ask what formula you used to calculate win/draw percentages based on ELO scores? Using the figures of 2809 (Shak) and 2763 (Karjakin), and using Nate Silver's ELO formula - 1/(1 + ...
   Dec-21-19 Grand Prix Jerusalem (2019) (replies)
DirkMcCallahan: I honestly believe that Chucky had a legitimate chance at winning Candidates 2013 had there been an increment/delay in place. He had winning positions in many of the flagged games, and of course, he beat both Carlsen and Kramnik.
   Nov-11-19 GCT Bucharest Rapid & Blitz (2019) (replies)
DirkMcCallahan: The homepage says that "finishing in the top 2 overall...will secure a berth in the 2020 Candidates Tournament." Surely that's wrong?!
   Oct-09-19 World Cup (2019) (replies)
DirkMcCallahan: According to Wiki it seems as if MVL has already qualified for a potential wildcard slot, so my question here is more theoretical than anything, but what would happen if no player met FIDE's requirements for the wildcard? Is there any provision in the official rules for such ...
   Aug-16-19 Sinquefield Cup (2019) (replies)
DirkMcCallahan: <Sokrates: 6 wins and 3 draws would be the best tournament result in chess - ever!> Didn't Caruana win Sinquefield 2014 with 7 wins and 3 draws? (Sorry, being nitpicky here!)
   May-09-19 Grand Chess Tour Cote d’Ivoire (Rapid & Blitz) (2019) (replies)
DirkMcCallahan: Incredible finish in the Amin-Nakamura game!
   Dec-05-18 Tiggler chessforum (replies)
DirkMcCallahan: <Tiggler> Thank you for your work on this! Of course, as others have pointed out, the games aren't truly independent trials (particularly in a case such as we saw in the 2018 WCC rapids), but it's quite interesting to see the theoretical breakdown, and I'd be curious to
   Nov-29-18 Carlsen - Caruana World Championship Match (2018) (replies)
DirkMcCallahan: <beatgiant: <DirkMcCallahan> Yes, you are confused. If Carlsen's chance of winning or drawing is .63, then <Carlsen's> chance of losing would have to be .37.> Of course; you're right. But I'm still not sure how Carlsen can have a .63 chance of winning OR ...
   Nov-28-18 Carlsen vs Caruana, 2018 (replies)
DirkMcCallahan: Do these games count towards the players' rapid ratings?
