Re: EidoGo Security Vulnerability Alert

I am the author of maxiGos (http://jeudego.org/maxiGos/index.php?lang=en) which is a sgf web player similar to eidogo.

MaxiGos has not this vulnerability.

Maybe this can help people that cannot patch eidogo easily themselves.

Re: Group Tax

Here is my summary of go rules evolution:

1) Someone found that placing as many stones as possible on a grid using a capture rule and a no repetition rule is an interesting game (stones scoring).

2) Someone found that one can stop the game without filling territories, count stones and territories ...

We do have a large reserve at GoGoD that has yet to show up in the database.

Re: The almost nearly minimal problem

[quote="fanfan"]Hello,

Here is a variation.

Question: Black to play. Can White place a living stone on both the 1-1 of the top left corner and the 1-1 of the bottom right corner?

Note: ko is probably not an option for White since he cannot win a ko fight in both corners.

Re: If God played Go, where would He play Black's first move

When Chuck Norris want to be kind with someone, he wins by playing only pass moves.

That means that pass move is not the best for sure!

Re: Goban dimension questions


Did line thickness, line spacing width and lengthwise stay the same besides the more generous edges?

Line thickness are the same in both directions (about 1mm). Line spacing widthwise and lengthwise cannot be the same. They can be computed using goban width and length, respectively (438mm-14mm ...

Re: Goban dimension questions

Hello,

Goban size can vary more than you expect.

My goban: shinkaya (japanese maker), thickness: 30mm, total width: 438mm, total length: 469mm, top and bottom edges: 19mm each, left and right edges: 14mm each.
