In the late 40s - early 50s, Alexander Kotov was probably among the top 10 chess players in the world. That is, the level of 2760-2780 by modern standards. But who now remembers this grandmaster?

“The center of the chessboard is a magnet, which pulls to itself all the pieces. Therefore the most beautiful and amazing moves, for me, are those with which a piece, counteracting the gravitational force of the center, suddenly fly to the edge of the board.”
