Fractional Team Go, Game 1

@Jon_Ko

I’m confused. My reading doesn’t match what three out of the four players recently did. I’m looking forwart to the game review .

Me too!

[Groin]

Same

Filling the J3 liberty would force the issue on the lower side, but I think it results in a ko that team white takes first, and I don’t see a good ko threat for team black. So I’ll continue capturing @Vsotvep’s throw-in stones with C9

[Vsotvep]

@yebellz, what do you think?

[yebellz]

Sorry for the delay!

How about capturing two black-team stones with a play at D2? I think that would leave a white/red stone at D2, if I’ve understood the capturing rule correctly.

[martin3141]

I believe that is correct.

[Vsotvep]

It does leave the stone? I thought it would also be removed, because it’s a white stone without liberties…

[martin3141]

Yes but similar to the “normal” rules, chains of other colors are removed first, potentially opening up new liberties for the recently placed stone. I formulated a detailed description in the other thread:

Fractional Multicolour Go

So far everybody who responded is in favour of suicide being allowed. So I would like to fix the following rules (specifically for clarity in the ongoing game): Suicide is allowed.

detailed description of the capture mechanic

Whenever a stone is placed, the following two steps are resolved by the rules: 1.) Check if any chains that don’t include the recently placed stone have no liberties, then remove all of them simultaneously. 2.) Check if any of the chains that include the recently placed…

[yebellz]

Basically, it’s like old chains vs new chains, as was defined for the Diplomatic Go games.

Ok, I’ll go with D2

[martin3141]

Am I seeing this correctly? If (Black | Blue) recaptures with E2, then (White | Blue) should not play F2, because the next move (White | Red) D2 would remove both E2 and F2.

So perhaps I should have taken the J3 liberty with my previous move. This is confusing …

[yebellz]

@martin3141

If (Black | Blue) recaptures with E2, then

D2 would be empty and (White | Blue) playing at F2 would be a single stone suicide.

EDIT: Oh wait, never mind, I misunderstood and misread, as usual for this game.

[Groin]

The furious game! Go check your temperature…

@martin3141

If (Black | Blue) recaptures with E2, then (White | Blue) should not play F2, because the next move (White | Red) D2 would remove both E2 and F2.

After the first two moves,

1. (Black | Blue) recaptures with E2,
2. (White | Blue) plays at F2,

it would be this:

It would then be (Black | Red)'s turn, where a hypothetical play at D2 would remove the two stones at E2 and F2, but would let (White | Red) make a second eye by playing at E2.

If (Black | Red) were to hypothetically pass, then (White | Red) could not play at D2, because it would be banned by positional superko, right?

However, if (Black | Red) were to play elsewhere, then (White | Red) could choose to play at D2, cycling the position locally.

Is that right?

[martin3141]

Yes I believe your analysis is correct. After your variation in the diagram, locally (Black | Red) would want to fill a liberty with J3, and (White | Red) can capture two stones with D2, but this way the F2 move did not make progress for team White. So (White | Red) needs to play the approach move F2 in order to capture the Black stones. That is unless I made a mistake, which has a high probability this game

[Here_We_Go]

It would be rude of me not to play E2 after all this analysis…
E2 it is.

[martin3141]

Don’t ever feel obligated to play a move just because of my wanna-be analysis!

[Here_We_Go]

Haha, to be honest, I would have played there anyway

[Here_We_Go]

E2 is my final answer, just in case that wasn’t clear.

[martin3141]

Right, here is the updated position:

Next to move is @Vsotvep

[Vsotvep]

I honestly see no way to prevent capture of either of our groups… I think I’ll play C8, no idea what else would make sense here
