PGN games with annotations

Hi there. Could you recommened me a site where I can download pgn annotated files of master's games? I read chess books to analyze games but I suppose it will be more effective if I use my computer, not real board. There are lots of pgn games without annotations unfortunately

This site has almost 14 years worth of master and grandmaster annotated games in the articles section. IM Jeremy Silman wrote dozens of articles. Each could keep you busy for hours.

Many master and grandmasters have blogged for years here.

Lamento no poder recomendar , solo juego con entuciasmo , aprendi mucho jugando con un pastor evagelista norteamericano.

I would like .pgn files too. The articles are too hard to follow on a computer. I prefer using an android app or .pdf reader if the explanations are in that format.  

Saludos  y seguir jugando ajedrez.
