Confusing middlegame

Some trainers say that no other master has such a terrific will to win. At the board he radiates danger, and even the strongest opponents tend to freeze, like rabbits when they smell a panther. Even his weaknesses are dangerous. As white, his opening game is predictable - you can make plans against it - but so strong that your plans almost never work. In the middle game his precision and invention are fabulous, and in the end game you simply cannot beat him.
