Beginner - Confused on scoring (9x9 game)


#1

I’m struggling to understand how I (black) lost by 6 points. From my understanding, I occupy/control 41 out of 81 spaces (>50%) AND have captured 9 stones compared to zero, so how did I lose by 6 points?


#2

Not familiar with the app you are showing but I would put my money on komi (the extra points given to White to make up for going second in an even game). Typically around 6.5pts


#3

Well it’s Chinese scoring obviously, so…

W=26+14
B=81-(26+14)
Result=81-(26+14+komi)

-6.5=81-(40+x); 41-x=-6.5; x=47.5
Komi=47.5-40 = 7.5

Komi was 7.5, par for the course in any modern 9x9 with Chinese rules.

Nota bene: prisoners are irrelevant under Chinese rules. It’s purely

[Live stones + Territory + Komi] - [Live stones + Territory] 

#4

Just for the record, White wins by 0.5 points with Japanese scoring and a (fairly standard) 6.5 komi:

Black: 11 points of territory = 11 points

White: 14 points territory - 9 captured stones + 6.5 komi = 5 + 6.5 = 11.5 points


#5

Playing diamond shapes after the game has (basically) concluded (with at least .5 advantage) is also indicative of botting.


#6

Thank you for going into the detail! I really appreciate it. That makes sense to me now.


#7

Or TPK play, ironically.


#8

After beating 5k on 9x9? :thinking:


#9

No clearly not in that specific case, I was just amused that bots and TPKs do the same weird behaviour in some circumstances :slight_smile:

Mind you it might be the exact same case here: a TPK using a bot and not recognising the mistake :smiley:
