Lesson 90

There are a lot of books on life-anddeath problems, and they vary in their difficulty and the concepts they deal with. To make the maximum use of lifeand- death problems, it is important to find the right one for your level. Most such books are indicated with the level of play.

As for solving the problems, the best way is not to consult the answers. Even if you’re not sure of your answer and cannot restrain your curiosity, don’t look at the answers and go straight on to the next problem. In real games, you have no chance to consult anybody else, and you can only depend on yourself.
