  • Win a game because of winning the last ko, under Chinese-like rules, while not letting the opponent get more than half the dame. That is, allow your opponent to play the dame as ko threats, and still win the ko.
  • Kill a group in a bent-four shape.
  • Kill or save a group using play-under-the-stones.
  • Fight a superko (a triple-ko under western rules, so it does not annul the game).
  • Win or lose a game because of the ruleset (that is, the winner would change if we switched from Japanese to Chinese or vice-versa).
  • Play out a losing ladder, but still win the game (I once won a tournament like that! I wasn’t being Lee Sedol-clever, I just really misread the ladder).
  • Win a game after some number of moves of mirror play.
  • One achievement per type of seki: seki with two common liberties; seki with one eye each plus one common liberty; seki where one player has two groups with one eye each, and the opponent has a group with two common liberties; seki with one eye each, plus a double ko (if another ko happens in the game, it either means one player has unlimited ko threats, or it’s a triple-ko, depending on the situation).
  • Specific to OGS: program a sequence of at least 20 moves in the autoplay, that gets played by the opponent.

I had this happen once, where I programmed in the conditional moves to play out a ladder that crossed the entire board, and my opponent actually played it out, since they had mistakenly thought it was a broken ladder.

I think I’ve never had 5 B2-bombers in the same game… But I’ve also never not had three empty triangles in the same game, except maybe games where one player resigned very early.

it would be really hard to program detector of many of the Achievements above

Agreed, but I wouldn’t want to limit the ideas to somewhat easily implementable ones.
Having them detected by humans might still be fun.

How about

  • Power Triangle: Play an empty triangle, that is at least five points better than any other move.

I kind of assumed that people were just having fun making these up and naming them, rather than proposing that they actually be implemented.

Shusaku badge: play a move that causes your opponent’s ears to redden.

Seriously speaking, that would be a really great idea. And seems there is already a lot of suggestions!

I didn’t take it seriously either. However, if it were implemented, it would be easy enough to self-report, and a mod could verify the achievement by inspecting the game. A list of approved categories could be published.

Note that could bring motivation, even more users maybe as this would be a new feature for go servers.

A little off-topic, but:
Interesting to look at the loss for each white play in the ladder: roughly 10, 8, 6, 6, 6, … 6, 3·5, 5·9, 1·6, 7·7, 1·1, resignation. I thought I had heard a higher estimate than 6 (¿about 10 or 15?), but I see nothing about it at Ladder at Sensei's Library.

Twenty years ago, I have been taught “You lose 7 points per move in a losing ladder”. But I have no idea where this estimation comes from.

Successfully cut five opponent groups and still lost the game = Cut out Loser

7 is the value of a semi-stone

one stone ≈ 15 points

Does the formula solve ur question?

Last Star: when there are not much chance to win or lose, and everyone timeout or resignout, the last player win the rengo

True God: when there’re no chance to win and all ur teammates get out, u play against a team of many players and u win

Chosen One: win a game by zero move, e.g. too many players before u have already ended the rengo game and u belong to the win team

Cheetah King: win a correspondence game in 10 min

Sun Friend: win a correspondence game over a year

GPU Challenger: win a game more than 360 moves

See this topic Ladder value? • Life In 19x19
Katago’s estimate is close, but not exactly equal to 7 points.
