Carlsen and his hippopotamus
The column "All in One" was introduced in in ChessBase Magazine about four years ago. On the basis of a single, but very extensively annotated game, you learn everything you need to know about a specific opening line. A compact format with which you can improve your know-how without much effort. In the current ChessBase Magazine #214 Igor Stohl introduces you to the Hippopotamus setup, a system that can be used with Black against practically anything.
