Fans of GM Khachiyan's series should know, when he needs a win as Black against a lower-rated player, get ready for a Philidor. Using his patented weapon, the veteran takes all the excitement off the junior's face by outcalculating him in a counter-attacking sequence. Khachiyan then masterfully conducts the ending, never allowing his opponent to gain any activity or acquire any hidden resources. So listen to the wise middle-aged GM and you'll never lose to a talented youngster again (hopefully)!
