Checking my scoring

[jambocraig]

Hi - Can anyone calculate my final score in this game.
It is komi 7.5 using Chinese rules (note - I am a beginner)

Thanks

black score in Chinese rules is just area in geometrical sense. Surrounded empty cells +
(not dead) black stones
same for white. But after you calculate white, you also add komi to result.
color wich has more points wins.

its simple

you can use score estimator to do it instantly

Thanks for the reply - so what do you think the score is in this game?
I ask, because I calculate a different value to the estimator…

I count black 38 points and white 43 points + 7.5 komi = 50.5, so white wins by 12.5, which should match the score estimator.

Thanks for the help - yep, this works for me

screenshot doesn’t look like real game. What do you compare? Score Estimator of real game and your count of this simplified position?

Draw a diagonal line. White has all 36 below the line, 6 on the line, and one above it.

Black has 35 above the line and three on the line.

The score before komi is 43 to 38, but with 7.5 komi, white has a 12.5 point lead.

What are you counting and getting with the score estimator?

I made the position up - just to test my understanding of the scoring system…

The help on the forum has been really useful (just need to play a few games - and maybe even win one…)

So did the score estimator give you the wrong answer? The AI estimator available in reviews has some mysterious behavior that I posted about before:

Does the AI score estimator not understand ko?

After a recent game involving a ko fight, I noticed that the post-game score estimator seemed way off. I was able to replicate it on a demo board: [Screenshot_20211114-222805] Black just played (and captured) at D5. White can’t possibly have any ko threats here, right? But the AI gives the ko to White anyway. What’s going on?

When you are actually playing a game, the estimator (if allowed in the game settings) is a simpler one that just counts the displayed black vs. white squares plus komi.

Chinese counting

Someone asked me a tutorial about how we count a game in Chinese rule. (He’s going to have to IRL.) The very first thing is to understand what we want to do. We are going to count all together, meaning the stones and the emptyness in the middle of the stones. We count only for one color and then we can see if this color occupies more as half of the board, or not. [Screenshot_2021-09-10-18-10-35-36] Here the game is finished. We remove the prisoners to the stock of stones (bowls), prisoner…
