:D
Really, each player has different weeknesses and will benefit from different things. Generally speaking tactics, playing over master games (older ones are probably a little more understandable) and playing longer time control games (and analyze after) will give very good benefit.
I am around 1400-1450 rating and really need a study plan to progress?
Can someone advice me were to start please?
Thanks
