Hello!

I am looking to study some closed games to improve my evaluation skills and positional sense. Are there any websites/ books which have these games annotated at a level that can be understood by an intermediate level player?

The type of games I'm looking for would be of a similar style to Karpov-Unzicker, 1974, seen below:

Thank you!

I guess I would pick a collection of GM games from someone known for closed positions, like Karpov here. Maybe Petrosian who has a posthumous game collection. I don’t have either collection so I can’t say for sure.
