The MAXIMSCHOOL chess school presents 172 exercises for beautiful combinations with victory, gaining an advantage, winning pieces and checkmating in a few moves.
After solving each exercise, the opportunity opens up to watch the entire chess game from which the position was obtained.
This application contains the games and combinations that came out after playing such a popular opening as Dragon variation in the Sicilian Defense, in which chess players who played with black pieces won.

The exercises are divided into 2 groups:
- A game with versatile castling
- One-sided castling game or white King in the center
