So you want to start collecting jp-rules-esque special cases which are resolved by rulings based on how they would play out given infinite time?
No I’m not collecting any special cases. I’m just asking a “simple” question
huh. I guess I don’t understand how this is meant to be played, then
Are there three points on a Goban that form an equilateral triangle?
my gut says no, and it feels like the sort of thing a relatively simple proof should exist for, but I can’t think of one
that is equilateral triangle in Taxicab(Manhattan) geometry
Go is not really Euclidean space anyway.
If there exists an equilateral triangle formed by three points of an infinite grid of rectangles a × b, then a/b is a rational multiple of √3
I don’t get why that follows, but I get that if it does, it completes a proof by contradiction that no equilateral triangle exists on an infinite goban with rectangular grid
A few more details. Let ABC be a direct equilateral triangle. Put the origin at A. Let (xa,yb) and (x’a,y’b) be the coordinates of B and C (x, x’, y and y’ being integers). The point C is obtained from B by a rotation of center A and angle 60°, so
x’a = (xa-(√3)yb)/2
y’b = ((√3)xa+yb)/2.
It follows that (x-2x’)a=(√3)yb so a/b=(√3)y/(x-2x’).
Let’s open the window, it’s getting a bit hot here.
That said, if the standard size of a goban is 22×23.7 then this triangle is almost equilateral
since 8/5×23.7/22 ≃ 1.7236
and √3 ≃ 1.732, the relative error is 0.5% and cannot be distinguished with the naked eye.
How to avoid fuzzy stone images?
When doing post-game analysis, sometimes the stones suddenly go fuzzy. That is, they are black or white dots surrounded by a corespondingly colored blur.
For an old go player, with old eyes, this renders the board effectively unusable. I cannot see the stone clearly enough, and it essentially ends my use of the analysis feature.
How do I avoid/undo this?
I sometimes encounter the same bug. Changing browser may help.
“Do the first (black), second (white) and third moves of a game have a title/name?” Google Translator.
A primeira(preta), segunda(branca) e terceira jogada de uma partida têm algum título/nome?
If I’m not mistaken, in Japanese the first and second moves would be called sente and gote respectively, the same terms that are used to describe initiative.
Thank you.
Why does go have such a strong overlap with developers and seemingly almost no overlap with designers?
It’s a poorly designed game
Who thinks it’s practical to need or require 180 of each piece to play a game on a 19x19 grid of lines on a wooden board
The sad thing is, some people unironically think this, that any game which needs to be so big to be good is a bad game, while ignoring that 9x9 Go is a much better game than most is not all they like, and many games they like would likely be better on a larger board
Do people say that, though? I never heard such argument.
The only context in which it makes sense is in Go (at least 19x19) being much less convenient to play on mobile than, e.g., Chess.
