The Fried Liver pattern: Nxf7 pulls the king into the open and turns the loose d5 knight into a target.
No score. Just the hunt.
We study your games — not one game. The patterns behind your losses, clustered across up to 50 recent games, named as principles you can carry into a game that looks nothing like the examples.
No reviewing every game yourself. The labor is done for you.
The specific drill, position set, or lecture that actually closes the gap — found and handed to you. In-app when drilling is fastest, pointed outward when a lecture teaches it better.
Honest about which path serves which pattern. Never generic.
Come back after a few games. We tell you, plainly, whether the pattern showed up again or whether you caught it this time. On your schedule — not gated to a ritual.
The follow-through no one-shot analyzer can give you.
diagnose → practice → did it stick? → the next pattern, or re-diagnose
GMSomeday studies your recent games like a coach, not a single-game analyzer. It finds the repeated chess idea behind the points you are losing, then turns the highest-leverage pattern into one thing to practice next.
The move was available before the position cooled off.
Forcing moves before quiet moves
Seen in 4 of your last 50 games.
Hunt forcing moves first.
It opens with your archetype — The Generous Winner, The Speed Blunderer, The Endgame Collapser — a read on what kind of player you are right now, built to be screenshotted, not skimmed. Underneath, each leak card shows the exact position where your win probability dropped, the move you played and the move you missed, and every principle the position is teaching, named — not just one.
You were winning in most of your losses. The positions were there — you just need to close.
Every missed chance renders on the custom greige board with the target square highlighted. Aspiration: the Fried Liver knight sacrifice on f7 you were one calculation away from finding, with the win-probability gain it would have brought.
The Fried Liver pattern: Nxf7 pulls the king into the open and turns the loose d5 knight into a target.
Each leak becomes its own mission. When drilling the pattern directly is fastest, you get a guess-the-move warm-up built from your own positions. When a lecture or puzzle set teaches the principle better, the mission points you there.
No score. Just the hunt.
After a few more games, the coach tells you plainly: the pattern showed up again, or you caught it. No streaks to maintain. No guilt. Just a coach who remembers.
You spotted the tension release twice and avoided it once. The coach remembers.
GMSomeday rescans your games, surfaces the leak costing the most win% right now, and alternates with Weapon of the Week — the winning pattern you almost reached but didn't play. The loop is simple: play, check in, hunt the pattern, come back and see if it stuck.
No daily streaks. No homework. Just the next right thing to work on.
Hi. I'm Gregory, 26. I'm not a professional chess player. I've played since I was a kid, and I still play almost every day on my phone. You can find me on Chess.com as potemkinnn and on Lichess as gregorrrry.
I've read books, watched courses, and solved puzzles. The material was useful, but it rarely matched the patterns that actually showed up in my own games.
That's why I created GMSomeday. It points at the recurring leaks in my games and gives me one mission to hunt next. It is helping me grow my rating daily. I hope it helps you too.
