March 22, 2018
There is an interesting article on draws by Qiyu Zhou at the ChessBase site:

The intro: People are generally worried about draws, which are often considered "boring", where games may last up to six hours. To the common viewer (non-chess player), this may seem dull, and many believe this has led to a decline in sponsorship. But what do the statistics tell us? Using data now available, Qiyu Zhou, a remarkably young scientist has undertaken a thorough study of the numbers and provides a paper on her findings.
The paper is: Draws in Chess over the Last 40 Years - A Statistical Analysis
The bio: WGM Qiyu Zhou [pronounced Chee-you Jo], born in 2000, is a Canadian chess player who has competed for team Canada at the Women's Chess Olympiad since 2014 and who won the Canadian women's championship in 2016.
Qiyu learned to play chess at the age of four in France. In late 2004 the family moved to Finland, and Qiyu won the Finnish Youth Chess Championships five times (in 2005, 2007, 2008, 2009 and 2010) in the U10 Open section. Also in 2010, she won the Nordic School Chess Championships in the U11 Open division in Sweden. In 2008, she won the silver medal in the U8 Girls section at the World Youth Chess Championship in Vung Tiu, Vietnam.
In 2011, Qiyu transferred chess federations from Finland to Canada. She won the Canadian Youth Chess Championship in 2012 and 2013, in the Girls U-12 and Girls U-14 sections respectively. She won the Girls U-14 World Youth Championships in Durban, South Africa, 2014.
Also in 2014, Zhou made her debut at the Women's Chess Olympiad in Tromso, Norway. She played board four for the Canadian team scoring 6.5/9 points. In the same year she also took part in the World Youth Under-16 Chess Olympiad in Gyor, Hungary playing board four for team Canada, which finished fifth. She finished first in the U-18 Girls category at the North American Youth Chess Championships in 2015 Toluca, Mexico. As a result, she was automatically awarded by FIDE the title Woman International Master (WIM). In September 2016, Zhou won the Canadian women's championship and as a result qualified to play in the Women's World Chess Championship 2017.
Some onsite comments
- This is a nice analysis and this young lady may have a promising career in the expanding field of data analysis and data science.
Unfortunately though, it doesn't address the core issue. The problem is not draw rate as a whole, but the preponderance of non-games.... Unplayed, GM draws
A well fought, fighting draw is a good chess game. If all of these draws were of the 'real,' fighting variety nobody would have a problem with that. Most chessplayers are aware that a 'real' game among two strong players, well played on both sides, should end in a draw more often than not. That is simply the nature of chess.
Parsing these statistics to weed out the GM draws is a trickier exercise. You can try to separate them based on number of moves (shorter draws tend to be non-games) but that wouldn't be entirely accurate because some short games are 'real' games, and many non-games are 30 moves or longer. The latter case is not an obvious or literal 'GM draw', but both players are happy with a draw and neither player is striving or doing much to break the equilibrium.
Whether the rate of non-games has gone up over the past 40 years or not, also isn't the core issue. The core issue is that, regardless of where it's trending, there are far too many of them. And there is no doubt that turns many potential followers off from the game
- I'd say the type of tournament is a very important factor too. It would be logical for the draw rate to be higher in a match than in a Swiss open. Would this explain the higher draw rate in the 1970s, where a significant part of the small number of games was played in Candidates and World Championship matches?
- Agreed, the problem of rating inflation affecting the result should have been avoided.
Also, rapid and blitz games should have been excluded as those obviously skew the results, especially considering there are more rapid and blitz events these days.
Even classical time controls have become faster leading to more mistakes and less draws.
The current Candidates are spectacular, but all we have to do is look at the qualifiers for these Candidates:
Sharjah 2017 - 74.1% draws
Moscow 2017 - 70% draws
Geneva 2017 - 61% draws
Palma 2017 - 73% draws
