Traps, Tricks & Mistakes: Routine Moves

Keeping the concentration for the length of a game is difficult. So imagine the huge effort that top players have to do throughout a whole tournament. And what can we tell when speaking about a complete chess career?
We know extraordinary examples of successful chess performance. For example, Magnus Carlsen who stayed 111 games in 19 months undefeated; or Sergei Tiviakov, 110 games in 11 months.

Nevertheless, there is an important difference, because Tiviakov played against opponents with a rating below 2200, while Carlsen has always played against top opponents.
