San-san practitioners
I [Calvin] did some kombilo searches to determine who the biggest practitioners of the 3-3 point are. Since far fewer players play it as black then as white, it’s important to separate them:
Most games in GoGoD as Black (>= 10), with frequency of player’s total games where they played 3-3.
| # | Freq | Player |
|---|---|---|
| 109 | 73.6% | Fujisawa Hosai (Kuranosuke) |
| 87 | 14.7% | Sakata Eio |
| 40 | 4.8% | Cho Chikun |
| 16 | 3.7% | Kitani Minoru |
| 13 | 5.6% | Yamashita Hiroshi |
| 13 | 4.0% | Ishida Yoshio |
| 10 | 1.8% | Seo Pong-su |
| 10 | 6.9% | Kudo Norio |
Most as white (>= 50)
| # | Freq | Player |
|---|---|---|
| 265 | 44.9% | Sakata Eio |
| 166 | 49.0% | Ishida Yoshio |
| 117 | 14.0% | Cho Chikun |
| 112 | 16.1% | Rin Kaiho |
| 101 | 19.9% | Otake Hideo |
| 98 | 13.2% | Hashimoto Utaro |
| 66 | 17.0% | O Rissei |
| 66 | 11.2% | Kato Masao |
| 61 | 15.9% | Fujisawa Hideyuki (Shuko) |
| 58 | 16.4% | Ma Xiaochun |
| 50 | 9.0% | Seo Pong-su |
But what does it mean to play 3-3? As a move in an empty corner? Or specifically as move 1? Surely not as an invasion of a 4-4 as that is very common.
