Losing to AI Taught the World's Top Go Player Where He's Actually Strong

You probably haven't thought of it this way: knowing you can't win might be exactly when you figure out where you actually can. Today, Korea's top-ranked Go player Shin Jin-seo began a three-game match against the AI KataGo. KataGo spotted him two stones, a substantial advantage in Go terms. Even so, Shin's practice win rate has been below ten percent. He hadn't seriously studied KataGo under these conditions before. There was no reason to. Once he accepted the match, he started asking: what can I actually count on? His answer was endgame and territory. KataGo vastly outmatches any human in calculation, and surprising moves haven't thrown off modern AI for years. But careful endgame play, holding ground, protecting what's already his, those are where he feels steady. The two-stone game makes it almost impossible to avoid fighting altogether, so the real question became how not to get swept up in KataGo's pace, and carry some control into the late game. He figured this out only after accepting he couldn't win on the AI's terms. A Japanese company founded 270 years ago recently gave one of its non-engineer employees access to Claude Code. Within weeks, they had built an internal tool that consolidated data scattered across Excel files, various systems, and old VBA scripts, and improved the company's dashboards. The same work might have cost several months and millions of yen to outsource. They didn't learn to code. What they brought in was something an outside engineer wouldn't have had: years of knowing exactly which numbers need to match, which errors cause the most trouble, which reports get asked for every meeting. The tool lowered the technical barrier; their business knowledge is what made the result actually useful. Different conditions, same rhythm: first getting clear about where your edge isn't, then seeing what's actually yours. Shin Jin-seo's practice win rate is still under ten percent. He says this is the first time he's seriously studied where his strengths are.
