self taught grandmaster

Has anyone purchased Self Taught Grandmaster? If so can you let me know if it is worth it?

Who is that by? Igor smirnov is a self-tought GM and i found his material has helped me so much.

It's okay. It gives you a general plan of action to work on your game.

I pretty much learned on my own getting to a mid 1800 FIDE. Though I did pay people and computer online a lot and analysed the games thorough especially the ones I lost at. Learn from your mistakes or loses or whatever lol

It doesnt teach you chess. Its a guide/instructions to learn chess. All vedios contains advices.

It recomends tools/websites. You should already know openings, endgames, planning etc. If not ask you to follow other courses(that means you haveto buy them).

It contains 93MB zip file.
