I kept losing to the same three players at my club
Every one of them had a pattern. The same opening every game, the same collapse under time pressure, the same reply when I pushed on the queenside. I could feel it, but I could not prove it.
So I wrote something that could. Chess Stalker is that tool. No company behind it, just one person who plays at your level.
Why trust it
Systems engineering first, a software engineering degree on top of it. I wrote the analysis logic, the site and the database queries myself, so when something breaks there is nobody to wait for.
A master's in cybersecurity is why the site stores an email address and nothing else, why there is no search history tied to your name, and why payments never touch my servers.
I also trained as a secondary school teacher, and it changed how I built this. A number on its own teaches nothing, so every figure here comes with what to do about it on the board.
Club player, not a titled one. I say it because it matters: I built this for the rating range I actually play in, where preparation still decides games and nobody has a second to scout for them. FIDE 1700. I compete less than I would like: two small daughters win that argument every weekend.
What I will not claim
The Twin Bot is an approximation. It mirrors an opponent’s openings and playing strength, not the way they think at the board.
A profile needs volume to mean anything. Under fifty games the report is a hint rather than a verdict, and the page says so before you read it.
No tool wins the game for you. This one only tells you where to look before you sit down. The moves are still yours.

There is no support team to route you through. I answer my own mail.
