LIFE Master AJ: I must agree with <Chessical> here. Many weeks ago, I took just the basic gamescore to chess club one Thursday night.
Most of the players there did not understand the doubling of the pawns, this seemed to be the place where most people had their biggest question about this contest.
About two or three years ago, I purchased the book, "Mikhail Chigorin, The First Russian Grandmaster," by GM Alexander Khalifman and also S. Soloviov. (Chess Stars, 1999.)
Having studied dozens of his games, I can tell you he liked to play chess ... in a VERY unusual way!!! He often preferred Knights over Bishops. He would often engage in unclear sacrifices and often wound up in positions so complex, mere mortals would lose their way. He also liked to UN-balance a position as soon as possible, in this regard, one can see that Tal descends from the same chess lineage as Tchigorin.
