The problem with openings

📚

Too much theory, not enough practice

Classic books drown the essentials in hundreds of variations. Impossible to remember it all.

🎯

You learn moves, not ideas

You know 1.e4 e5 2.Nf3... but then what? Without understanding the plan, you're playing blind.

💀

Traps you discover too late

Every opening has classic traps. Knowing them means avoiding 50% of quick losses.

A guide that gets straight to the point

Not another 500-page book. A format designed to learn fast and remember long.

📄

1 page = 1 opening

Everything fits on one sheet: position, idea, mistakes to avoid, traps, variations. 2-minute read.

🎨

⚡

I spent years avoiding theory. This guide made me realize that knowing 5-6 solid openings is enough to play confidently up to 1800 Elo.

My son uses it before tournaments. He has his favorite sheets that he reviews the night before. Result: +200 points in 4 months and much less frustration.

Finally a format that respects my time. I play on Lichess in the evening, I don't have 2 hours for books. One sheet = one new repertoire tested.

No, and that's the point. Elo Booster gives you the essentials to play each opening correctly. To go deeper on a specific opening, a dedicated book is still useful — but you'll know which one to study.
