You play a game of Go. You review it with AI. You see where you went wrong. You nod thoughtfully, close the review, and then... make the exact same mistake two games later.
Sound familiar? You're not alone. It's probably the most common frustration in Go study.
The Gap Between Knowing and Doing
Understanding a mistake and actually fixing it are very different things. When you review a game and see that move 63 should have been a shoulder hit instead of an attachment, that's useful information. But information alone doesn't build habits.
Think about how other skills work. A tennis player doesn't just watch video of their bad serves — they go practice serves. A musician doesn't just listen to the passage they stumbled on — they drill it until it's smooth.
Go players, traditionally, haven't had a clean way to do this. You review the game, understand the mistake, and then hope it sticks when a similar position comes up.
What Training Mode Actually Does
AI Sensei's Training Mode closes that gap. Here's how it works:
- You upload and review a game — AI Sensei analyzes your game and identifies your key mistakes
- You mark positions worth practicing — hit "Remember" on any position during your review
- The positions become practice problems — they get saved to your personal training set
- You practice with smart scheduling — problems you get wrong come back more often, ones you nail gradually fade out. It's like flashcards, but for Go positions.
The problems aren't from a generic problem set. They're from your actual games. The positions you struggled with. The mistakes you really made. That's what makes it different.
Why Your Own Mistakes Are the Best Practice Material
Generic tsumego collections are great for building reading ability. But they have a limitation: they don't know what you specifically get wrong.
Maybe you always misread the timing of a 3-3 invasion. Maybe you consistently choose the wrong direction for a splitting attack. Maybe your endgame technique is solid but you collapse under pressure in capturing races.
Training Mode targets exactly those weak spots. Because the problems come from positions where you actually went wrong, you're training the specific patterns your game needs most.
It's like having a coach who says "I noticed you keep making this type of mistake — let's drill it until you get it right." Except the coach has analyzed every single one of your games and never forgets.
The Practice Loop
The most effective way to use Training Mode is as part of a regular review cycle:
Play → Review → Remember → Train → Play again
- Play your game (on any server — Pandanet, OGS, Tygem, WBaduk, wherever)
- Upload to AI Sensei and review your key mistakes
- Hit "Remember" on the positions that matter most to you
- Practice your saved positions in Training Mode
- Play your next game with the corrections fresh in your mind
Over time, the mistakes you keep practicing are the ones that stop showing up in your games. That's not a theory — it's how pattern recognition works. Repeat the correct response enough times, and it becomes your instinct.
Not Just for Strong Players
A common misconception is that AI review (and by extension, Training Mode) is only useful for dan-level players. In reality, it works at every level — the mistakes are just different.
A 15 kyu might save capturing races and basic life-and-death positions they missed in their games. A 5 kyu might practice direction of play and when to tenuki. A 3 dan might drill subtle endgame sequences and ko timing.
The AI doesn't care what your level is. It finds where you lost points, and you choose which positions to train. The practice is always matched to your actual level because it comes from your actual games.
No Other Tool Does This
Most Go analysis tools stop at showing you the review. They'll tell you what went wrong and what the AI would have played. That's valuable, and plenty of tools do it well.
But none of them take the next step of turning those specific mistakes into practice problems you can drill on a smart schedule. It's the difference between diagnosis and treatment.
AI Sensei's Training Mode is, as far as we know, the only tool in the Go world that completes this loop. Review your game, save the key moments, then practice them until they stick.

Try It
Upload a game at ai-sensei.com and review it. When you spot a mistake that feels important — one you know you'd make again — hit "Remember." After reviewing a few games, open Training Mode and start practicing.
You might be surprised how much harder it is to find the correct move under pressure than it was to understand it in review.
That gap between "I understand" and "I can do it" — that's where improvement lives. And Training Mode is how you close it.
Training Mode is available on all AI Sensei subscription plans. Upload your first game for free at ai-sensei.com.
