The Grand Prix Attack Bb5 System is both an agressive and positional chess opening. White prepares an attack on the kingside with an early f4, while maintaining the threat of doubling black’s pawns with Bxc6 – applying similar positional concepts as found in the Nimzo-Indian Defense. If you are a 1. e4 player who has trouble against the main lines of the Sicilian Defense, and you don’t want to dedicate dozens of hours of valuable chess studying time to memorizing all of the variations so you can achieve an ending at .43 – why not try a different system to get better results with less effort?
