Zenon Franco guides readers through 50 top-level games, challenges them to guess key moves correctly, and poses questions at critical moments. Points are awarded for good answers, and at the end of each game, a score-chart rates the readers performance. If you do not like the points-system, you can simply study the book - it is destined for intermediate and advanced players. About a half of games deals mainly with positional play, the rest with tactical or attacking games and endgames. Author is a grandmaster from Paraguay who now lives in Spain. He is an experienced chess trainer (Paco Vallejo). Index of games and openings
