GeauxCool: Excellent 19 move Miniature!
Gruenfeld knew more opening variations than any half dozen of his colleagues put together. Study the vigorous games of his early days because later years he used this knowledge to draw colorless games. -Fine
5.Bg5 is the refutation, if instead 5.dxe6 fxe6 6.cxb5 d5, then black gets a strong attack for the lost pawn.
8.Nb5! Na6 (forced)
Gruenfeld now has development advantage which calls for a quick attack.
9.e4 Qxb2? This loses. Blacks best was 9...e5
12.dxe6! Surprisingly efffective
17.Bb5! Decisive. Bogolyubov could have resigned here, but he decided to allow mate instead.-Fine
