In 40 Minutes, You’ll Know What
To Do On Every Move
You will not find these three anywhere else. Not in a book, not on YouTube, not in any course you have already bought. I built them because they did not exist.
Attack Or Develop!™ — The Thinking System
Three questions you ask before every meaningful decision, that tell you what to play in any position — with no calculation and nothing memorized. Most players do not believe that is possible until they use it. You will have it working in tonight’s game.
The Phase Priority Shift Principle™
When to attack and when to develop is not a fixed answer — it shifts as the game moves through its phases. And there is one hidden phase where most amateur games are actually decided, where players make the wrong call and lose from a position they were winning. I will show you what it looks like and how to see it coming.
The Override Principle™
Some moves attack and develop at the same time — while quietly killing whatever your opponent was planning. They are almost always the strongest move on the board, and almost nobody is looking for them. You will know how to find them.
You will learn all three in the masterclass, free — plus the roadmap that connects them to your openings, your tactics and every phase of the game, all the way to 2,000 Elo.

Dr. Mike Jansen is one of the fastest-growing chess YouTubers, a peak 2,100+ Elo online player, and the creator of Attack Or Develop!™ — the world's simplest and most powerful chess thinking system.
He was stuck at 1,000 Elo for 15 years — through college, grad school, and a full doctorate — until he turned the diagnostic methodology he uses as a Doctor of Physical Therapy onto chess itself, and broke through to 2,000+ in less than a year.
Today he coaches busy adult players with his full system — his students have gained up to 400 Elo in a single month* — without grinding endless puzzles or living on Chess.com.
