when i was your rating, studying games helped a lot (it still does now). it can do more than one of the following:
- help you understand the structures that result from your opening
- help you understand general plans from your openings
- help you understand different pawn breaks in different structures
- show some positional ideas you can apply in your games
- demonstrate certain key principles (eg. principle of two weaknesses)
- provide examples on attacking/defense
- etc, etc, etc
it can also be pretty fun
I'm curious if you have an opinion on what a beginner to intermediate player (1200-1300 rating) can take out of grandmaster games and secondly if analysing games by slightly stronger players is worthwhile.
