Kramnik Leads Fighting Chess Index Top 50, Radjabov At Bottom
The top 50 of the Fighting Chess Index, introduced by Australian grandmaster and economist David Smerdon, has GM Vladimir Kramnik in first place. GM Teimour Radjabov, who was criticized this week for playing quick draws at the Superbet Chess Classic, is last.
Smerdon introduced his Fighting Chess Index on Thursday on his blog. He explains it is "a composite, weighted measure of the combativeness of top chess players" and notes that it is based on data of the last five years before the pandemic.
Smerdon has combined data about the frequency, length, and color of drawn games from top players to provide a single score for each individual, which he argues "can be used to compare the degree of ‘fighting chess’ among players." The top 50 below includes the active players with the highest average rating based on their games between 2015 and 2020.

Smerdon calculated the percentage of draws, "short" draws and short draws with White as well as the average length of draws for each player. He chose 30 moves as the threshold for a short draw in accordance with Sofia rules.
He then ran a principal component analysis, which he explains as follows:
"[It] combines all of the metrics above, weighs them in such a way as to avoid double counting (e.g., it recognizes that someone with many short draws will also have a low average draw length), and extracts one number to represent the ‘hidden concept’ that these measures might explain—in this case, 'fighting chess.'”
Smerdon also adjusted the scores such that players who more often play opponents near their own strength, such as in more round-robins, aren't punished for scoring more draws than similar players who play games with bigger rating differences, such as in large open tournaments.
Teimour Radjabov
Radjabov's bottom place in this list won't be a surprise for the pundits who criticized the Azerbaijani grandmaster for his (theoretical) short draws in Bucharest this week.
Thank you @GMGeorgMeier !

My point exactly! https://t.co/n01iDiE3mU
Between 2015 and 2020 Radjabov drew more than 60 percent of his games and played a short draw almost once in every five games. Smerdon: "The 2022 Candidates contender finishes 50th in almost every variation of the index that I tried."
In a comment to Chess.com, Smerdon said: "I wasn’t taking a position on the short draws debate. I’d actually been meaning to make this index for a while, just for my own interest (I like playing around with chess data now that I’m a semi-decent researcher). The timing just worked out!"
Vladimir Kramnik
To see Kramnik at the very top might seem surprising but the 14th world champion, who retired from classical chess events in January 2019, seemed to have a different approach in his final years as an active player. In 2015-2019 he recorded a short draw in fewer than four percent of his games.
Vishy Anand
The story is different for another world champion. GM Vishy Anand, still active, is in 47th place. Smerdon explains Anand's score as follows:
"Since 2015, Anand played a short draw in roughly one out of every seven games, with an overall draw rate of 55 percent. On the other hand, some of these short draws may be aimed at conserving energy in blitz and rapid events (i.e., events with multiple rounds per day), and these are more likely to be played with Black (42 percent of his short draws)."
Smerdon does emphasize in his article that the index is based on 2015-2020. Anand is surely a much more combative player if you look at a wider time frame, and Smerdon plans to do just that in a follow-up post.
Top 100
In his article, Smerdon also provides the FCI scores for the top 100 players by rating in 2015-2020. The top 10, in order of most to least fighting, is Kramnik, Fabiano Caruana, Magnus Carlsen, Maxime Vachier-Lagrave, Wesley So, Levon Aronian, Ding Liren, Anish Giri, Shakhriyar Mamedyarov, and Anand.
Of this top 100, the four most combative grandmasters (just ahead of Kramnik, who is in fifth place) are GM Igor Kovalenko (Latvia), Gawain Jones (England), Hrant Melkumyan (Armenia), and Sanan Sjugirov (Russia).
Hess, Gunina
Smerdon mentioned a few names of highly combative players outside of the top 100. For instance, there is our regular Chess.com commentator GM Robert Hess, who has a score of 94.0. Smerdon explained: "When he does draw a game, which happens only 12 percent of the time, it lasts more than 60 moves on average."
Not surprising is GM Valentina Gunina's high score (93.6) with which she tops the FCI for female players. Smerdon said: "Her FCI score is consistent with her recent performance in the FIDE Women’s Grand Prix in Gibraltar, in which she played 10 decisive games in a row before drawing her final round after 135 moves."
It's well worth visiting Smerdon's blog and checking out his full article, which has more explanations and clarifications and also answers questions such as, “Isn’t it impossible to measure fighting spirit with statistics?” and “Aren’t stronger players more likely to draw their games because chess is inherently a draw?”
guys, it's official. I'm okay.🔥😅 https://t.co/BUWc3zXRAB

Very interesting Blog by @dsmerdon. What do you think my rank will be on the ‘Fighting chess Index?’ ;) https://t.co/PPcNDKQf14

My hypothesis: There is no format in chess that eliminates non-games (aka short draws).

This is why I believe the solution is player-based, in that organizers must drop chasing rating averages and use tools like @dsmerdon's new fighting chess index to create exciting fields.
Radjabov clearly believes rating points matter much more than actually playing chess when it comes to getting invites. That's on organizers. They need to step up their invite game beyond rating lists. @dsmerdon's tool can help. I hope he's hired to make more.

I'm too scared to ask @dsmerdon about my score. It's not gonna be good. I have sinned. 60 at most. https://t.co/BxrP0tvwdS

Hi @dsmerdon I'd like to know if I'm a drawmeister :)
