Strange Pro Opening 4
Though I have seen arguments that the 6-3 point is good, I had never seen 6-4 points played in a pro game prior to this one. (Not that I had ever specifically looked, either.) The first one seems to be played in the spirit of exploiting the high approach to the komoku, but that doesn't actually take place in the game.
MarkD: It 6-4 point was played by a lot of pro players, for example in the game Nabeshima Ichiro, 4d - Takagawa Kaku, 2d; Go Seigen, 5d - Sekiyama Riichi, 4d; Kitani Minoru, 6d - Sekiyama Riichi, 5d and so on. As you can see these are really famous players.
Blake: Well, Go Seigen and Kitani Minoru I would have expected; that was the "New Fuseki" era, after all. Still, it seems less popular than any of the other corner moves, even 6-3 and 5-5.
Disappointingly enough, the upper left soon devolves into the standard 3-4 point high approach keima joseki by transposition. The lower right, however, is an unusual enclosure, and seems like it might offer more possibilities...
Kobayashi never makes any serious invasions or reductions against the corner--I was surprised, since the 3-3 is so invitingly open. I suspect he may have thought Yoda had prepared some special plan for that eventuality.
In the end, Yoda wins by 3.5. I don't think you can call the 6-4 opening a great success, though.
