I’ve found some recent pro games that were largely influence oriented. Top pros play the Chinese variants and orthodox for safety, because that’s how they make a living. Playing center oriented is risky, they won’t bet their salary on it.
I came across an interview where a pro player was discussing non-territorial openings. He clearly stated that center oriented (tengen for example) are not bad. They just open too many possibilities that it’s very hard to review and make a viable opening that will have a safe win/loss ratio.
Only amateurs, who noticed these openings weren’t played that often, flagged them as bad openings.
But they are indeed a perfect way to learn direction, invasions, attack and they are an immense source of fun.
When money or fame is not a consideration pros jump on the occasion and play very unorthodox openings. High level games on Tygem are a proof of that.
As for Takemiya have you seen his games? He plays nirensei every single time and attacks.
As soon as the occasion presents itself, he puts the stone on the middle hoshi. (unless his opponent afraid of his style plays there first)
So I don’t know where you got that information from…
So yeah, sanrensei is definitely a viable option even at top pro level. Don’t spread wrong information please.
Sefo must be talking about Seo Bongsoo (see page 17 of “British Go Journal”, Edition: Autumn 1994, No. 96)…
These days  the emphasis is changing from corner, side, then centre to just side then centre, since it is difficult to develop the corner. We can thank Takemiya for this change. Korean players have always had to play to win in order to earn money, so they have concentrated on the corners and were afraid of the centre because of its vagueness, and they did not research it. However, Takemiya was brought up by a rich family, and the Japanese don’t allow their players to think about money, so he researched into this unknown area. Having been beaten several times by Cho Chi-hoon, who found his weak points, he perfected his centre strategy as a way of playing against Cho. He has done the most research and has shown us how fantastic, magnificent, and deep the centre is, like the Universe. Before him, Korean amateurs and professionals used to avoid the 4-4 point; now this is the most popular opening.
