Chess is a game that requires no physical exertion, only mental acuity. This is why it is dominated by young players, as they are able to recover faster from the rigors of tournament play. The effects of aging on a chess player's game are inevitable, but that doesn't mean that older players should stop playing. It is interesting to compare chess to another mental game, Go, in which players never train against computers.
Magnus Carlsen and Fabiano Caruana are two of the younger generation who have realized the importance of human interaction in maximizing their chess potential. The gradual deterioration of the skills of older players also keeps the competitive chess scene fresh. It is worth considering why two generations of chess players have been so poor, with the exception of Magnus Carlsen. This could be due to the fact that after a long day of playing or studying chess, one feels exhausted.
The analysis does not take into account outliers or other possible disturbances in the data. Chess relies on a healthy body more than most people realize, and the effects of aging on the body can be seen in the brain, which is reflected on the chessboard. A unique aspect of this study was that it highlighted the bias in previous studies when it came to analyzing older chess players' results. Levon Aronian and Boris Spassky have similar tastes for the West and have spent parts of their careers living there.
