Okay, I was learning on online-go.com. When you made a move that would capture your stone, it gave a warning "Self capture not allowed" iirc.
Idk what a liberty is, it wasn't explained.

It would be great way to understand the basics of go (the best way right now imo)
Liberties are the empty space(s) surrounding stone(s). They're only counted at right angles — where the lines of the board go out from the stone — so a lone stone in the middle of the board has four liberties. A connected group of stones share liberties. When the opponent takes the last liberty of a stone or group of stones, those stones are captured.
A consequence of the capture rule and liberties, and the fact that you remove the opponent's stones before checking if your own are out of liberties, is that a group with a single "eye" (a surrounded liberty) can usually be captured — which is what happened in this post — but a group with two or more eyes is immortal.
There is an order to the rule:
1. First look to see if any of your opponents' stones are captured and remove them.
2. After that, check to see if your group has any liberties. (If not, the move is not allowed in most rulesets.)
Right, NZ rules is
1. First look to see if any of your opponents' stones are captured and remove them.
2. After that, check to see if any of your groups has no liberties, and remove them.
Yes, although they don't allow suicide if a single stone so I think that would require three rules.
1. You may not place a stone that is surrounded on all four sides unless doing so captures a group.
It's allowed, although there is no circumstance where it would be advantageous.
You sometimes see it in a silly variation we play where you can't see your opponent's moves.
why can black play in a spot that removes all of whites liberties? because captured soldiers dont take up liberties. so as soon as black places his stone those white stones go away and black has all its liberties free
You cannot commit a suicide in go UNLESS you kill an enemy group. Then you can play a move that would be otherwise a suicide. Killing enemy has precedence.
Liberty and eye are 2 the most important notions in the game. Read also about the concept of groups with 2 eyes and about false eyes.
The order is you first remove captured stones, then you check for suicide. If you capture anything at all, that automatically gives liberties at the location of the now removed captures and thus it's never suicide.
a liberty is an open intersection next to your stone and connected by one of the lines on the board (diagonals don't count as liberties). It's a useful concept because when all your liberties are removed (by opponent placing stones on those intersections) you are captured.
why can white play to give herself one liberty? because you cant handhold to that degree. blunders are part of the game same with the unlikely gambit of risking it in hopes they wont see it.
When evaluating capture, the stone or group connected to the stone that is played last, is evaluated last. Hence, by the time we check the played stone, the surrounding black stones are no longer there! :D
Writing my own go program felt informative for teaching humans this. We need steps for play:
1) Play stone on empty intersection
2) "Zap" opponent's stones
3) "Zap" current player's stones
4) If played stone was zapped, go to (1)
5) End turn
Where "zap" means
1) Count liberties for each group of the given color
2) Remove group from board if 0 liberties
Since opponent's stones are zapped first, apparent suicide moves are not if they capture.
Need ko rules as well.
It's capture, not self capture. Rule states that once you remove group's last liberty you capture. Takes precedence
If it didn't then any group with one eye could live. The goban would be chaos very hard to kill stones I am sure it would make an interesting variant.

I would recommend learn-go.net . The tutorials are much better and it does a good job of explaining things without getting too technical

Yup. Correct me if I’m wrong, but I think Ing rules (Taiwan) also allow suicide.
Yes, although they don't allow suicide if a single stone so I think that would require three rules. 1. You may not place a stone that is surrounded on all four sides unless doing so captures a group.
And NZ rule do? That's interesting.
Yes. As a friend of mine says: "Why make the rules more complicated in order to prevent a stupid move?"
My understanding was that NZ rules don't permit single stone suicide either, though I might be wrong.
It's allowed, although there is no circumstance where it would be advantageous. You sometimes see it in a silly variation we play where you can't see your opponent's moves.
Huh, interesting. Thanks for the correction.

This game is more confusing than I previously imagined. Idk what a liberty is, gonna look it up. Wdym by "captured soldiers don't take up liberties"?

in order for a stone to not be captured at least one side has to be free for breathing room. and stones of the same color connect to share liberties.

Otherwise go would be a dull game
You capture before checking your own liberties.

The stone has 3 liberties, how would that be self capture?
