We can all choose to do this if we do want to play for a win, and the end result is playing for a win in a more secure relative-risk-free manner. But Karpov emphasizes playing for a win quite often instead of a draw and modeling some of the same positional opening choices of Tigran Petrosian such as the Caro-Kann with the black pieces against 1.e4. It is this playing style that Anatoly Karpov has admitted during an interview at Gibraltar, to making use of. But in retrospect now, we can be selective and choose the more interesting wins of Petrosian using a relatively risk-free style. Often this would result in draws for sure which may not have given him a daring attacking reputation during the time of his career. His prophylaxis style of reducing risk and trying to seek the logic of the chessboard, and reducing unnecessary risks, in general, contribute to him being very difficult to beat. Petrosian was a Nimzovich and Capablanca fan which explains many of his playing attributes. Petrosian's extreme playing style has fascinated and intrigued future generations of players trying to study and fathom his games. Even Garry Kasparov had extreme difficulties when playing Tigran Petrosian, losing the first two encounters in a dramatic fashion. Future World Champion Vladimir Kramnik called him " the first defender with a capital D". He was considered by many to be the hardest player to beat in the history of chess. Petrosian really did not like losing! In fact, Petrosian's consistent skills and resourcefulness to avoid defeat earned him the nickname " Iron Tigran". He is also one of the most successful world champions. Tigran Petrosian has created the reputation of being one of the most sophisticated World Champions with specialisms in exchange sacrifice, prophylaxis, and prevention strategies.
