Oh, what would you say the best way to improve is then?
I've been doing puzzles for quite some time now, and I believe it is really helping me improve. But I've distinguished between two different types of puzzles, easy puzzles, which is usually ones that I can solve by just looking at the position and determining the right move in a few seconds. And hard puzzles, which take longer to solve because I need to actually calculate to find the answer. Since I've been doing both methods, I wonder which one is more effective for improvement? Are easy puzzles better for improvement, or harder puzzles?
