By the way, in the 2000 World Championship match Kasparov played the Catalan,
which ended in a draw after 38 moves and the title for Kramnik.
Is The Catalan Solid?

The Catalan is somewhat of a backwater, but it is solid, and some players achieved great results with it. Take Genna Sosonko, for example. Used the Catalan 28 times between 1987 and 1998, never lost a single game. His opponents - Karpov, Lautier, Huebner, Timman, among others. Korchnoi and Beliavsky used it extensively. Kasparov played it at least 15 times. Nonetheless, it is vastly less popular than the KID, QGD or the Nimzo-Indian.
In yesterday's forum we discussed whether the Grunfeld was solid. After
that exciting game today I ask, "Is the Catalan solid"? When it comes to World
Championship play does it hold up over time?
Also, is there any other record of doubled outside passed pawns in a World
Championship game? I thought that was really unusual.
Will there be coverage on ChessTV on Tuesday? The scedule shows the
next game is not until Wednesday.
