While it’s not exactly an adversarial attack, there was a bot that could win a lot of games playing the Black Hole opening on CGOS

Black_hole on CGOS

Today, Dinershteyn in his group pointed out that there’s a new interesting bot on CGOS that always plays black hole fuseki and it’s pretty good. http://www.yss-aya.com/cgos/19x19/cross/black_hole.html Of course, there’re questions of hardware, playouts and such. But it’s tiny bit exciting. Perhaps, one of minigo experiments? Dinershteyn is so excited because he likes unusual openings (those faces of spectators lol): http://sports.sina.com.cn/go/2014-12-11/18057443728.shtml

"Black Hole" Fuseki Lecture by Alexander Dinerchtein 3p eng subs.

I think at some point one has to decide what’s actually “fair” though. Or one has to consider what adversarial really means.

You can probably consistently beat a fixed version of Katago by picking another Katago version with better hardware or more playouts etc.

Is a newer version of Katago that has a good winrate against an older version of Katago an adversary?

I mean it’s probably improving from self play anyway.
