Resuelto el misterio comentarista

Hará ya un tiempo hablé de que tenía una serie de partidas comentadas en mi ordenador que no sabía de quien eran. Hoy he llegado a la conclusión que quien las comenta es Alexandre Dinerchtein ya que me he encontrado este juego que os pongo a continuación de una partida entre él y Lee Chang-ho. Como veréis más adelante, en los comentarios del juego dice que es un juego que tuvo contra el coreano y eso me despertó por así decir encontrar quien era el misterioso comentarista de los juegos que tengo de pro. Y por lo visto no son baratos conseguirlos según parece poner en la página de su web.

He de admitir que la existencia de derechos de autor en este tipo de "documentos" me era esperable, más todavía si se tiene en cuenta la polémica que existe con los derechos de autor en los simples kifu (registros de partida).

La partida que me ha llevado a encontrar el autor de los comentarios es esta, de ahí me puse a buscar y encontré un documento en .txt que me confirmaba mis sospechas:
