The Grünfeld Formula

The story goes that a low-rated player once bravely asked Viktor Korchnoi his advice about what opening to play against a stronger opponent. "Play Grünfeld" was the grumpy reply. "Play Grünfeld against everything apart from 1 e4."I have no way of verifying this story, but it certainly inspired me to think about whether this was possible and the end result is this new ChessBase course.Naturally, a universal approach using ...Nf6, ...g7-g6 and ...d7-d5 as the base would be very useful for players of all classes, saving time and energy and promising a fluid, dynamic position.I've found Korchnoi's advice to be mostly true, but there are a few important exceptions when Black can do better than just trot out the Grünfeld Formula.
