If you're stuck under 1000, it's probably not because you need more theory.

It's because last week you copied one setup, this week you tried another, and tomorrow you'll abandon both after one loss.

Under 1000, games are decided by hanging pieces and having no idea where your pieces go on move 10. Not by the Najdorf.

What actually works — the foundation of winning games:

• One White system. Same squares every game. I use the London: d4, Nf3, Bf4, e3, c3, Bd3, Nbd2, castle.

• One Black setup. Caro-Kann vs e4. Slav-style vs d4. …c6 and …d5. Castle. Stop.

• 20 tactics, not 2,000. Hanging pieces, forks, pins, skewers, back-rank mates. That's the list.

• 15 minutes a day. 5 minutes puzzles. One rapid game. 5 minutes finding the first blunder. Then you close the laptop.

Play 20 games without changing the first ten moves. Track where the first blunder happens. If it moves from move 8 to move 18, you're improving even if the rating hasn't caught up yet.

Rating lags the streak. Switching systems resets the streak.

That's the whole product I built. Not a community. Not 1:1 coaching. A foundation.
