Yes, I understand the possibility of these sorts of cases, but I just think that the creation of these sorts of situations are quite rare, especially for kyu-level play.
Maybe dan-level players would be better at engineering these sorts of situations, but also their opponents would try to compensate for these possibilities.
How much handicap do you think it is worth for dan-level players?
My hypothesis is that for 5 kyu and weaker, the advantage is no more than “1 stone” (0.5 komi game).
I think if you allow living with two kos, it would be worth at least two stones for dan-level players just because of all of the invasions which would become possible. I really can’t know for sure without trying it out, though.
I think you’re underestimating how easy it is to create these shapes! The effect is basically to turn (most) false eyes into real eyes. So you don’t have to do anything fancy to set up ko shapes, just invade everywhere and you’ll find that all your groups live 
I think I’m on the record somewhere else on the forum (although I can’t find it now) as saying that this handicap could be worth around 9 stones. Right now I’m thinking it’s probably a bit lower… maybe 7 stones at dan-level? Very rough guesses, because I’ve also never played this variant 
I would add that it’s not just about life and death. It’s about any ko anywhere which black always win.like in sabaki technics or like when you connect on ko and such things. Well you need to be atease with how to use ko of course.
And I feel this to be quite an advantage
Some tiny tsumego: Black to play, black can recapture kos. Can black live?
It doesn’t seem to me? I mean as long as you can avoid that black makes 2 ko or a ko and an eye which look possible to avoid
Black can in fact live!
If black B1 white A2 which makes Miai to capture the stone or play D1 to avoid a second ko
Other B moves look obvious to kill. I don’t see the trick
A1-C1
C1-A1
A2-C1
I don’t see
You have to discard all your previous intuition about life and death and consider all the possibilities
I really don’t see. I enumerated all black possible moves and white answer.
Ok still one
Black D1
Ok that’s fun B lives.
This classic tactic will no longer work so well for white.
This would be fun if it’s ever implemented somewhere !!
What if you could also move one of your opponent’s stones?
Interesting, my immediate thoughts are “Then the game can cycle with one stone being moved back and forth” and if we prevent this with say Superko rule, then “Can any group be alive forever?”
Pushing a stone back and forth could make some interesting ko fights. I think that without some modification to the rules, it would be hard for more than one group to live (you can push all eyes to the edge of a group, then fill them). I think it might be fixed if you can only move an opponent’s stone that is not touching one of yours.
Whats an example of a group that would live forever because if this rule? And are ko threats still a valid strategy to kill/live?
Edit: OH I see you’re saying that eyes would not guarantee life. That is a huge wrench in the game lol 
There’s variants which might rule the whole Go flow of trying to score a game, but it doesn’t mean they wouldn’t make a good capture Go variant for instance.
So if one is also willing to make capture Go variants and variants with different goals, then that eases the burden slightly of trying to make games make it stably to scoring also.
Two stones on a 2x2 are alive forever (assuming passes lift ko bans). The player with the stones can just pass when their stones get moved, and move to capture any stone played by the opponent.
Another variant idea is to give players the option to remove one of their stones as their move instead of placing one.
Suddenly eyeless lumps of stones can live, and (depending on the scoring method) some neutral points turn into points.
Hello everybody! May I ask you a question here? I am looking for a Go-Variant, “GO on triangular grid”. But all variants I still found on Google, says that every stone has 3 liberties. But what about a game, where one stone has 6 liberties? Yes, maybe it’s hard to capture any enemy’s group, but I think this would be a good territory game, with occupying territories. If somebody knows this variant - give me please its name or links to it! (I try to add an image I found - )
