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. Look out for those differences! This is a course full of opening ideas and suggestions for Black, against all of:

• 1 b3
• 1 b4
• King’s Indian Attack
• 1 f4
• 1 c4
• 1 Nf3
• QP Systems including London, Torre, Trompowski, Barry Attack, Colle, Stonewall.
• A comprehensive list!

• Video running time: 6 hours (English)
• Exclusive database with model games

Grünfeld

The Grünfeld Defence is part of the group of openings which arose only when a new understanding of the struggle for the centre was developed. In 1922 the Austrian grandmaster Ernst Grünfeld (1893–1962) introduced to practice this system which would later be taken up by Botvinnik, Fischer and Kasparov and which nowadays counts as one of the most important defences to 1.d4. In the diagram above, which shows the main line, Black has actually exchanged his d-pawn for the white b-pawn. And White has not only been able to set up the ideal centre e4/d4, but his d-pawn is even supported by the pawn on c3. The secret underlying the vitality of the black position can be found in the subsequent piece development and the counter-attack against the d4-square. Black only requires two moves, ...c5 and ...Nc6, in order to be able to exert strong pressure against the d4-pawn.
