The Segunda Gran Fiesta de Ajedrex UNAM in Mexico City brings us an amazing line-up with Magnus Carlsen, Judit Polgar, Lazaro Bruzon and Manuel Leon Hoyos participating to a "cuadrangular": 4 rounds KO system with the strong brigade playing Rapid and Blindfold games (remember the late lamented Amber event?). During the UNAM Festival - November the 24th at 1pm ICC time - Magnus Carlsen will be Public Enemy number 1 (!) in the "Carslen vs. the World" game!
