I am a Professional(whatever that means) ... Professionals are strategists who place a high value on the exactness of their game and rarely let their emotions get out of hand. Professionals like to keep things under control - they don't like to take undue risks, either by attacking the opponent or allowing themselves to be attacked. Instead, Professionals like to exploit long-term weaknesses. While they deal with long-term strategic and positional factors, they don’t rely on vague, intuitive judgments - for the Professional, chess is an exact, calculated science. Mikhail Botvinnik (1911-1995), the sixth world champion, was a clear example of the Professional. Botvinnik was the first top player to develop in the Soviet Union, and was thus considered to be the patriarch of Soviet chess. Botvinnik was one of the first to take a professional approach to preparing for competitions, which included a big emphasis on physical exercise, opening preparation, and deep analysis of his own and his opponent's games. Botvinnik took chess very seriously, but ironically considered himself not to be a full chess professional and worked as an engineer as well..... To be honest , I am engineer too... LOL....
