Any experienced player knows how a change in the character of the play influences your psychological mood.
Weaknesses of character are normally shown in a game of chess.
Chess - it's a nonmainstream game. And the irony is that when you look at Hollywood, it kept using chess as the symbol of intelligence for its heroes, for its top characters, all the time. So it's from "Casablanca" to "Harry Potter." You always have chess as a very important element to demonstrate intelligence, while in normal life people think it's just a weird intelligence - like AI.
I don't really like discussions about a supposed Russian national character.
