I do doubt that there is sufficient data available on Go as it is not popular enough. But lets face it 7 points guaranteed profit is way easier to utilize than initiative.
For chess it clearly visible quotation from wikipedia "database between players with similar Elo ratings, commissioned by GM András Adorján <https://en.wikipedia.org/wiki/Andr%C3%A1s_Adorj%C3%A1n>, showed that as the players' ratings went up, the percentage of draws increased, the proportion of decisive games that White won increased, and White's overall winning percentage increased.[15] <https://en.wikipedia.org/wiki/First-move_advantage_in_chess#cite_note-15> For example, taking the highest and lowest of Adorján's rating categories of 1669 games played by the highest-rated players (Elo ratings 2700 and above), White scored 55.7% overall (W26.5 D58.4 L15.2), whereas of 34,924 games played by the lowest-rated players (Elo ratings below 2100), White scored 53.1% overall (W37.0 D32.1 L30.8)." A clear difference and even the lowest category is pretty strong. Around Elo 1500 1st move probably means next to nothing Why would it be any different in Go? I think 1st move advantage is far less for weak players Go than in chess, because doing a Null move is far easier 2015-11-05 13:39 GMT+02:00 Petr Baudis <pa...@ucw.cz>: > On Thu, Nov 05, 2015 at 09:03:38AM +0200, Petri Pitkanen wrote: > > 2015-11-05 0:04 GMT+02:00 Hideki Kato <hideki_ka...@ybb.ne.jp>: > > > > > The correct komi value assuming both players are perfect.
