One of the most mysterious aspects of chess is the positional sacrifice. Sacrificing material in order to get positional compensation can be a risky decision. Often a positional sacrifice doesn’t lead to direct victory. It’s an investment to gain for example active play or control over key squares, ranks and files. It’s very important to be able to predict as good as possible if the positional advantages will compensate the sacrificed material.
To give you some more insight in this matter I’ve made a few training videos in which I explain positional sacrifices played in grandmaster games. I hope that these examples will inspire you so you can use this knowledge in your own games.
