The action of the story takes place in the chess country of Eight Eight and... in the inner world of an ordinary fifth-grader boy. As befits a fairy tale, its heroes - the pioneer Vasilko, the grandmaster Venividivitsin, the magical electronic bun Ainka - and even the author himself have many adventures: funny and incredible, dangerous and not so dangerous. But, perhaps, the main character of the fairy tale is... the reader’s imagination.
