Rookie Question on Scoring

Hello, OGS Forum–

I’m a brand-new beginner & have finally made the leap from playing various AI’s to playing actual people (I’m kicking myself for not jumping in several months ago–it’s so much more fun, & the community members are great).

I was fortunate enough to play a really fun game yesterday, & luckily managed to win.

When I went through the post-game analysis, though, I couldn’t quite understand the scoring. I would have thought that the upper right-hand corner centered around M12 belonged to white: should I have played at M12 to kill the false eye, or perhaps I’m missing something else?

Here’s the file (I hope) & thanks in advance for any advice:

Is this the game in question?

That corner was definitely White. My instinct locally in response to L12 would indeed be M12

But White still ended up killing there; the upper left weaknesses which black played to first seem more pertinent to me for study

Ah, I see the players marked the upper right as seki; they should have marked it as dead

In the future, sharing the URL is easier to view than sgf. (Assuming you played on OGS) i uploaded the file here in case it helps anyone else samanisms29 vs. dh98mkvi)

Edit: just use @Samraku 's link

Your are correct that that corner should be scored as white territory. M12 is unnecessary, indeed it loses a point. Those black stones should have been marked as dead by clicking on them before accepting the score.

Thank you all for your prompt responses!

I have to confess that I didn’t really look at the scoring at the end of the game, & just accepted it (it’s a good lesson for me that sometimes there can be discussion about how particular stones should be marked).

BTW, where do I go to look at how the scoring was done to see how that corner was scored (I’m still learning how to navigate the app…)? :slightly_smiling_face:

And yes, the game was on OGS & I’ll provide the URL rather than the SGF going forward.

Thanks for all of your help!

I’m not sure how the app displays it, but on the website you can go to the end position with all the score markings and the upper right does not have the little squares which indicate a point was scored there

Ah, got it–

And yes, his upper lefthand corner invasion rattled me: when he played B12, for reasons that will forever remain a mystery I played A12 instead of closing the cutting point at B10.

General chaos on my part then ensued as I continued to bungle the defense–much to learn for sure! :grin:

Thanks again for all of your help!

Sometimes OGS’s auto-scoring can be wrong, so be sure to review everything before accepting :slight_smile:

It was a pretty decently played game as a beginner!

Glad to see you’re reviewing and reflecting on what you did wrong - It’s one of the best ways to get better.

If you want to get better fast, IMHO the most important thing to improve on prior to 15k is basic life-and-death. 95% of games between 15k or lower level players end in the death of big groups.

IMO Tsumegos (life and death problems) are the best way to learn how to not die and kill your opponent’s groups.

This is a great collection of beginner puzzles by a Japanese pro : Play Go at online-go.com! | OGS (Warning: It gets hard pretty fast - The “Difficulty” rating is not accurate at all. I can’t solve some of the 25 kyu problems as a 5 kyu)

Thank you & great counsel–

I’ll start working the life & death problems for sure!

It’s fine if you don’t do life and death problems, most important is to play and enjoy the game. Build your experience on the multiple aspect of the game.

I’d say that you ll be more asking for studies above 15k not so before that.
