Waltheri 21st Century Games Widest Path
Unfortunately, Waltheri has become a little out of date at the time of writing (October 2021), having no games played later than March 2020. This means that the "new games" search, to query games from the past year, can't be used.
The nature of this search doesn't allow one to see the percentage of the first move directly, but it's about 28,820 games. The komoku has a little less than 18,000.
18,033. Over double the equivalent hoshi in the lower left (7,354 games).
8,762. The a komoku is also very popular (7,366). The nirensei is surprisingly rare, with only 1,407 games.
5,274. The hoshi is also common (3,335).
1,916. Approaches to White's komoku also have a lot of play.
Thus far we have followed the widest path for Waltheri, which was centred on a line most popular in the 2000s. However, we now deviate.
In the all games path, was played as the split a, and had 798 games to the approach's 645. In the modern games path, is the approach (650) and the split is the runner up (551).
(514). Other moves have been played, of course, but none have more than 53 games.
(276), the slide, excludes post-bot games. However, there isn't a single hit for at b.
(141). I was surprised that at c only has one game.
(89). A straightforward opening proved most attractive.
(88). So this is why Black didn't defend at the 3-3 point earlier.
(59). In post-bot Go, will often be at .
(54). In 2013 and 2014, a was experimented with to deny White the ladderbreaker.
(42). White doesn't usually take the ladderbreaker yet. At this point it becomes clear that our focus has been drawn to an opening played from 2013 to 2016.
(34). Fixing in what would seem to us to be post-bot style. The direct capture has been played, but is recorded only once.
(26). An interesting reversal of move order, the "ladderbreaker" being played after the fix.
(9). a has five games. It's interesting to note that from this point on Waltheri's modern games path exceeds in length its all games path, which had 23 moves in the 2017 testing.
(8) (7) (6)
(5). A simple move. This line was only seen in 2014.
(3). a branches, as well as at .
(2). b branches. This is technically the end of the path, as Kim Jiseok continued with a in one game and c in another. However, the game Ke Jie -- Meng Tailing 2013 transposes into this position due to using the order. Including this result gives us a second hit for at c.
