Boundless energy of young chess players inspires envy from those who are olderBEGINNER’S CORNER865321b c cl e f g hWHITE MATESHint: Divert the queen.□ □ □Although chess is a sedentary game, it is - surprisingly - physically demanding. At peak moments, theheart and respiration rates of chess masters are comparable to those of boxers or football players.High energy expenditure leads to fatigue, which in turn leads to error and blunders, the bane of players’ existence. It is no wonder that there is a premium on youth in chess.1 was bemused some years agowhen Vladimir Kramnik combined that at the age of 19 he was acking the energy he had as a relative youngster of 17. At the time, 1 attributed his fatigue to a prolific night life, but now I am not sure it was caused by that single factor.Recently, 25-year-old Peter Svid-ler, a three-time Russian champion, contrasted his play with that of 17-year-old Ukrainian prodigy RusianPomonarlov.“Compared to him, I am a very old man,” Svidler said. “He told me that it’s a pity that the game (weplayed) finished so soon. He could sit down and play another one. Rusian has so much energy to% *spare.But even Pomonarlov may seem«*like a tired relic compared to 8-year-old Izak Shapiro of Boston, who at the 2000 National Elementary School Championship told a reporter: At a tournament like this, 1 run around to get my energy out. Then I sit 10 minutes to get calm for the game.”Stamina will be a key issue during the upcoming month-long world title match between Kramnik and 37-year-old Garry Kasparov. Who will be affected the most by fatigue, the younger challenger or the veteran world champion?Below is a 1992 win by a teen-age Kramnik against Armenian grandmaster Smbat Lputian.KramnikLputian1. d4Nf62. c4g^3.
