In my estimation (I play go), beating Ishida Yoshio at 4 stones in a non-simul game [1] probably requires a player that's at least 4 dan amateur.
[1] Professionals usually play amateurs simultaneous games. That is, 1 vs. many. The quality of play improves dramatically if they are playing a single game. In this case, a single game Ishida probably wanted to win.
- CocaKoala 13y agoyeah; there are some people in the comments suggesting that that Ishida might not be playing at the level of a top 9p right now, but this is still pretty significant and a very impressive feat.
- awwducks 13y agoYep. The difference between Ishida and a top pro today probably isn't more than 2 stones.
- hyperpape 13y agoEven that is probably high. I think any professional in the world could lose on 5 stones (c.f. http://www.computer-go.info/h-c/index.html http://www.computer-go.info/h-c/index.html).
- MichaelGG 13y agoI was under the impression that the difference between nearly all pros is 3 stones or less.
- hyperpape 13y agoProbably accurate for active professionals in the big three countries, and probably a bit generous. I doubt there are many professionals, if any, who need three stones against the best. In fact, top western amateurs might be competitive on three stones. There has been some compression of professional strength in the past 50 years, so there may be some older professionals who need that much. Additionally, there are players with professional ranks who no longer compete, or only compete in Western tournaments. They may need three stones.
