Tactic Toolbox Grunfeld - Michal KrasenkowIf you want to know an opening, you should understand its typical positional ideas and plans. It is also good to remember variations. But this is not enough. You should also know the typical tactical motifs or your opening. This trio of strategy, variations, and tactics forms a conscious and subconscious image in the mind and helps you to find the right moves. The Grünfeld Defense is an active opening, which often leads to sharp, double-edged play, and tense tactical fights. Therefore the tactical part of the Grünfeld-image is extremely important and should be steadily developed. The most effective, timeproven way to develop tactical abilities, imagination, and the ability to calculate variations, is practice. Poets say, “No day without a line”, aspiring chessplayers should say “No day without tactical exercise”.
