From Equal to Helpless Before Move 15?
Fix These 3 Early Mistakes That
Ruin Your Chess Games

Polish legend Johannes Zukertort once said: “Chess is the struggle against error.” And boy, do they show up early, then haunt you for the rest of the game! In Avoiding & Punishing Mistakes in Chess, you zero in on the 3 early-game mistakes that decide whether you suffer or thrive in the next 40 moves.

How often does this happen to you?

You play safe, sensible chess. You’re not hanging pieces. And everything feels fine at first…

But suddenly you’re getting pushed back.

You start losing control of key squares, while every move of your opponent comes with a threat.

Before move 15…

⚠️ You find your whole army pressed against the first three ranks.

⚠️ You slip to a 1-to-4 numbers disadvantage on the side of the board that matters.

⚠️ Or worse, your king sits stuck in the center, while enemy pieces line up for a breakthrough.

If this feels like your story every other game, you’re probably making one of the common errors covered in Avoiding & Punishing Mistakes in Chess.

This strategy course teaches you how to detect, avoid, and punish the 3 early-game mistakes, which keep players stuck around the 1000-1700 Elo level.

Inside, you will learn from Boroljub Zlatanovic.

He’s an International Master with a peak FIDE rating of 2438. He was the 1995 Serbian Youth Champion, a 2-time University of Belgrade Champion… and a dominant force in state team events.

He switched his focus to teaching in 2015, earning the title of FIDE Trainer. Since then, he’s written 11 chess books and courses. Each one aimed at helping club players clean up their play and raise their rating.

Zlatanovic trained in the Soviet School of chess — so he could care less about ever-changing engine lines. Instead, he cares about helping you build skills that bring lasting improvement.

Combine all of the above with his full-time job at a public utility company… and you get a “working class” chess master.

He knows what it’s like to squeeze chess study into a busy life. That’s why his lessons pull double duty…
