Success has a way of complicating things.
Not in a bad way, it’s like weeds in a garden.
It means the ground is good, fertile.
Just because seeds grow, doesn’t mean they should.

Go back to what worked.
The fundamentals.
99% of chess is the fundamentals.
Forks, pins, skewers, pawn structure.
The 1% is where you get to add your flair.

Don’t put all your time on the 1%.
Identify what worked, and why it worked.
Maybe the medium changed.
The fundamentals persist.
