Iā€™ve changed my mind yet again. With Maharani playing D7, it feels more doable to attack Martin, and Iā€™m still seeing a chance to win in that scenario. So I just have to go for it, even though I donā€™t really want to betray Martin, itā€™s in my best interest to do it. And itā€™ll be more fun than a draw :slight_smile:

The plan is to eliminate Haze during this round. The obvious move that Haze has is H7, so that will be my first move. My second move is G9, which should collide with le_4TC, since heā€™ll play G9 first. My third move will be D8, which should also collide, but with Maharani, if they follow my advice. In case G9 is blocked on the first move, le_4TC will play D8 as his second move.

All in all, it looks like Haze will only have a chance of survival by playing H6 after playing H7, or by playing H1, which is not in their interest, as it will make le_4TC harder to kill.

So my moves:

  1. H7
  2. G9
  3. D8

Welcome to the private kibitz thread @Maharani!

Thank you for playing and especially for taking over a very tough position.

I guess the next move should be g1 for martin. Hopefully it collides with le_4tc stone. Then maybe haze can play g1 to capture the white stone and reduce the eyespace. Or maybe they can play in another order. Hard to know if say le_4tc and Vsotvep will try to play both moves at g9 and d7 simultaneously.

A question I still wonder is when do players get eliminated, is it if they have no stones at the end of the round no stones on the board at some point, including say first second third preference place after collisions?

I still donā€™t understand if Vsotvep gets a better position if Martin was eliminated rather than le_4tc. I just imagine drawing a line across the board, at either row 5 or column E. It feels like if martin is eliminated, le_4tc is probably guaranteed about 35ish points. I would say Vsotvep needs to at least get points beyond the main diagonal A9-E5 to match that, maybe its close but I imagine le_4tc leading.

If le_4tc was eliminated at some point, before various betrayals and things, or say somehow now with teamwork, maybe Martin has 25 points, and Vsotvep 21 ish points. E3 looks like a fine point then for both and depending how the killer blows are landed maybe Vsotvep ends with a stone there or in F2 is area. Suppose they secure 15/16 points in the bottom left, I think it ends up a very close game - maybe even the dame could swing it with Chinese rules.

Maybe something like the above, and maybe the person who gets the better eye points when the groups are captured can come out on top. (or sneak in some dame while waiting to capture the group? - I did this for Vsotvep on the left image :slight_smile: )

I think though even now, provided that le_4tc doesnā€™t get to play g1 itā€™s very hard for them to resist capture from three other players working together right? le_4tc couldnā€™t capture Haze solo and a lot of other points are eyes and would be suicide to play in.

Just in case Iā€™m not here tonight, or in case I might be here but had a few drinks and forget to move:

  1. H4
  2. J3
  3. D7

Some reasoning:

First fact: Martin cannot be killed without two people collaborating. Unless Martin commits suicide (not unlikely if he can use it to try to force a draw), there is no reason le_4TC would help me kill Martin, or the other way around, if itā€™s not in our benefit.

Second fact: le_4TC has 27 points, assuming he gets A1, and H1 gets removed at some point.

Third fact: I have at least 21 points, assuming G9 will become mine at some point.

I therefore need to find 6 points, or le_4TC will not agree with capturing Martin.
Before Martin is captured, I can make sure that Haze gets removed, and that le_4TC does not have any stones in the freed area. There is no way they could prevent this, except by capturing me.

By playing A8, le_4TC has made his throw-in capturable. Without Martin choosing sides, my stone at A6 will be unremovable for le_4TC, but on the other hand, I have a way to remove his two stones.

H4 and J3 are vital: if le_4TC gets both those points, I have no way to get the same number of points by filling up Hazeā€™s gap. Therefore it is vital that I obtain at least one of those two points. H4 will be more useful in the unlikely scenario that I end up working together with Martin and Haze to capture le_4TC, so H4 will be my first move. Without it I see no way to convince le_4TC to capture Martin.

The scariest scenario at the moment, is that le_4TC plays J3, while I play H4: this can prompt the three of them to capture my group, which is great for le_4TC, but also raises Martinā€™s win chances. Haze will probably go along with it as well, since theyā€™ve got nothing to lose, and I assume Haze is vengeful. Iā€™m basically putting all my eggs into the basket that le_4TC does not play J3 on this move.

Now that I think of it, if I donā€™t get to play H4, it almost certainly must be because le_4TC blocks it, which means itā€™s likely heā€™ll play J3 as the second move. Iā€™ll have to play J3 second to block, or I will lose on points. G9 is not a priority in this scenario: if Haze plays it, my third move should be D7 to capture

I actually forgot that this could be an option, that le_4tc could just be ahead on the board as is, and just not try to capture either. Tbh though, if le_4tc is in the lead, they donā€™t really have a good reason not to try to capture any of the other two players martin or vsotvep, except in the case le_4tc is unconditionally alive - 4 solid eyes.

I now think the only way that someone doesnā€™t get captured is if le_4tc is alive unconditionally and waits for scoring. Otherwise you could just threaten to ally with vsotvep as martin, or vice versa, itā€™s losing outright vs a chance of winning. I donā€™t think le_4tc (or I) would necessarily want to accept a draw from a winning position, but then again as yebellz has been saying that depends on the players and their ā€˜utilityā€™ functions etc.

I still donā€™t see why capturing le_4tc is off the table, and has been for many rounds.

I think this becomes even more unlikely or close to impossible if le_4tc can get g1 and g2.

ā€¦ I think vsotvep with 3 eyes is probably fine. Itā€™s likely haze has to die to even fill the outside liberty at g9, and then the other three points need to be played simultaneously (which I guess is hard or impossible to block - kind of like with rock paper scissors type strategy, where you could accidentally fill your own liberty because thats what you thought an opponent would do)

I think I agree with this one though as a backup to capture haze and gain liberties.

whitemartin3141 taking at H1 in round 26 was ultimately a gift to redle_4TC, who is now in great shape to solidify 4 eyes and invincibility.

Assuming that redle_4TC eventually does solidify four eyes and clears out blackHazeā€™s stone at F2, he will have 26 points, while not even counting the dame at J3 and A1.

If no one else is eliminated, redle_4TC will win.

Was just checking the other thread now! Thanks for posting the board here

This is ouch for me. I think le_4tc is likely unconditionally alive. G2 is a clear next move, but I guess that g2 and f1 are probably miai. It would take all of Haze, martin and Vsotvep to play F1,G2 and H1 and even then it might be tricky to stop the fourth eye. The best they can hope for is probably the following with all chains ā€˜newā€™

Initially I was thinking Haze and Martin might have had some trick planned with the collision at G1, but it just looks like an accident, especially with B9 played following it up. It feels like B9 was not urgent especially with the liberty at D7.

I think Vsotvep misjudged le_4tcā€™s priorities and is thinking maybe too diplomatically for the endgame rather than tactically short term.

I like Hazeā€™s fighting spirit to still play F2. I mean I guess thereā€™s only a handful of legal moves but even still!

I also think itā€™s a great response :slight_smile:

It does make me want to find a turn order which kills le_4tc though :stuck_out_tongue: Maybe something like

M: 1.H1 2.G2 3.F1?
V: 1.F1 2.H1 3.G2?
H: 1. G2 2. F1 3. H1?

Thereā€™s possibly a bit too many variations. In theory le_4tc can block one of first moves, which would suicide the other stones. The other trick might be to intentionally collide the first move like le_4tc 1.C1 and then get to play 2. G1 and recapture all the stones reverting the board position back - is that legal?

Definitely would require reading out the variaitons.

Actuallyā€¦ I think I miscounted.

If whitemartin3141 secures the dame D7 and A1, and eventually captures blueVsotvepā€™s stone A6, he would have 27 points. Of course, he would only have two eyes and could be vulnerable, however, blueVsotvep could play kingmaker and let whitemartin3141 win.

So, I guess we will have to see if blueVsotvep works toward eliminating whitemartin3141 instead.

Without counting the dame at J3 and G9, blueVsotvep currently has 21 points. So, his chances of winning hinges entirely on how much spoils he could potentially get from eliminating whitemartin3141 and blackHaze.

The board can cycle, but if the same position is reached after three rounds, the game proceeds immediately to scoring with all stones alive. Maybe I should have made the threshold a bit higher to avoid pathologically ending the game a bit too early. However, it is also pretty easy to avoid cycling by filling a dame or throwing in a stone elsewhere.

Testy exchange between Vsotvep and Haze in the game thread.

It seems highly likely that Haze gets eliminated in this game, so they have little to lose, and maybe they just want to tank Vsotvep as well.

Great end game discussion going on in the game thread!

I think @le_4TC already hashed out a lot of the points that I would have liked to make:

Current board position

Letā€™s look at the current area score

  • Iā€™ll assume that the inside stones at A6 and F2 will be removed, and that all other stones are hypothetically alive for now
  • redle_4TC has 26 points
  • whitemartin3141 has 25 points
  • blueVsotvep has 21 points
  • blackHaze has 5 points from very tenuous stones
  • There are dame available to grab at A1, J3, D7, G9
  • Of course, filling D7 and G9 would eliminate blackHaze freeing up five more points of dame that would be up for grabs between whitemartin3141 and blueVsotvep

Now, where does the game go from here?

  • In theory, any player could still be eliminated, but I think that the chances of redle_4TC or blueVsotvep being eventually eliminated are very slim, and omit analysis of such possibilities
  • Unless whitemartin3141 is eliminated, redle_4TC is limited to a max of 28 points (by taking both dame at A1 and J3)
  • However, if blackHaze is eliminated, which I think is likely, that would free up 5 more points, of which whitemartin3141 is likely to grab a few. And, of course, itā€™s possible that whitemartin3141 also gets the dame at A1 instead.
  • Thus, if blackHaze goes, itā€™s quite possible for whitemartin3141 and redle_4TC to be tied in points (maybe at 28 or 27), or for one of them to be slightly ahead of the other (maybe by only a point or two).

blueVsotvep could play kingmaker in this endgame:

  • By not contesting the dame freed up by the capture of blackHaze, he could give whitemartin3141 a lead in points over redle_4TC, and by refusing to work with redle_4TC, he could hand the win to whitemartin3141. This is hypothetical leverage that blueVsotvep could exert on redle_4TC in order to get redle_4TC to vote for a 3-way draw.
  • Alternatively, with whitemartin3141 in the lead, he could instead work with redle_4TC to eliminate whitemartin3141 and reduce the game to a two-player fight over the cleared space. Thus, this is potential leverage to get whitemartin3141 to vote for a 3-way draw.
  • Hence, by making threats to throw the game to the other, blueVsotvep seems to have the leverage as kingmaker to force a 3-way draw.
  • However, blueVsotvep may instead choose to eliminate whitemartin3141, which would give him a potential shot at winning. However, maybe redle_4TC would have a slight edge in that two-player fight. Speculating about the nature of these players, I think this is the most likely path.
  • Whether they end up going down any of these routes depends on their individual risk tolerance/aversion.

I also understand Martins frustration, and would probably be considering resigning if in his shoes also. If the other players wanted another round to try something out, maybe wait a few turns but I understand the want to resign.

Round 28

None of us are in a real hurry. I need to prevent the three of them working together to capture me, which can happen in multiple ways: I could play G9 and le_4TC J3, or Haze could play G9 and le_4TC J3, or I play J3 and Haze plays G9. All of those options are dangerous, and I donā€™t want to risk it (although I think the chance is pretty small both Martin and le_4TC would want to capture me).

If this plan exists, then le_4TC will play J3 this round, and Haze might try to get G9 in as the 2nd or 3rd move. Iā€™ll play D7, which should capture Haze in case this plan is happening. I will play D7 as my third move, and try nothing else. Iā€™ve got not much to lose, I think.

I think I should talk about this plan with le_4TC, so that if he chooses to betray me, heā€™d do it in a way that makes sure Haze gets captured anyway.

It seems that blueVsotvep is not thinking so far out about the endgame and is more preoccupied about the remote possibility that he may be eliminated.

Note that D8 and D9 are intentional collisions with existing stones, so he is hoping that D7 either slips in as the last choice, or someone else fills it before then.

Looking back again at the potential endgame, I think that an eventual elimination of both whitemartin3141 and blackHaze might still give redle_4TC a strong edge to take the victory.

If blueVsotvep is risk adverse, and his recent kibitz logs seems to indicate that he might be, I think his best path would be to eliminate blackHaze, but then allow whitemartin3141 to get a higher score than redle_4TC. Then, he can leverage his way into a 3-way draw with the threats as I described earlier.
