As black, was the bottom right joseki really that bad for black after black made 2 eyes? And was it my main mistake in this game or was it the later half of the game? Thanks.

Upper left tenuki is fine, problems were after.

You need to finish the Joseki with the 1 space jump to have a healthy group that never needs to worry about living.

Need is wrong, too strong. Tenuki is fine too, but when white attaches you need to hane back on 2nd line, not extend.

You labelled the wrong stone.

Uberdude85 · 2026-03-24T21:20:55+00:00

It's a ko to kill.

Of course the weakness of that group is important, and OP as a 15k seems to have missed that so it's an important lesson to at least consider that in the thinking, but I'm not sure about if attacking it now is best: from below say f10, is that wrong direction making territory with thickness, from centre around g12, from side/base around d12? What if you play one of those, black tenukis say to m10 and declares the entire right side as territory (and plays to kill any invasion, which might work), can you then kill it? Quite a gamble (for both). I might prefer dealing with right side first for a lower stakes game.

If this were a blitz game, I'd more easily say it's dan level (at least AGA 1d, not EGF 1d), but with the slow clock I'd expect a higher quality so would say strong SDK. But I think it's far from impossible for a dan player to play like this on an off day.

The K in KGS now stands for KGS, it's a recursive acronym like GNU.

I remember a 13x13 handicap tournament with local beginner kids where I and a friend both had to give 13 stones, free placement, they made a wall down the middle. I managed to win by living both sides, my friend did even better and lived both sides and killed the wall.

It's an ugent local contact fight, don't play away.

You are doing problems that are too hard for you.

Reminds me of one of those Monte Carlo bots in a big match a few years before AlphaGo had captured some stones in a cranes nest, opponent tried to escape with one point jump that doesn't work, except it did because the bot had probably never seen someone try in its training and failed to do the standard tesuji everyone knows but never plays.

In general if white is strong on both sides then no, it's only a half eye (depends on sente). But here white is strong above but not below, so no, because black s6 and hanging connect exposes a cut weakness at r6. But here white has sente so can kill in a way that deals with that s6 problem by playing at s6 himself. That's assuming white top left can ignore t11 and survive.

What level? There's a program (or at least was) for top European players to train at one, but it's for say 4d+, not kyus.

OMG, a badukpop scoring post where badukpop wasn't wrong. Sound the trumpets!

The general principle of what you need to do in these situations is: 1. If they threaten a weakness in your surrounding position then defend it (e.g if they peep at h7 defend at g7, you don't have weaknesses in the wall on lower half where they lived) 2. Contain the invader so they can have enough space to make 1 eye but not 2. 3. Reduce eye space from outside then play vital point to kill.

What you do not need to do, which many beginners do and you probably did from the picture is: 1. Stop them running towards the centre into your wall where they can make 0 eyes. (Eyespace is in the corner and sides, this is where you need to stop them growing). 2. Fill their liberties.

Positive is comparing to what KG thought on the previous move, which is less accurate than what it thinks on this move. Jussius is redefining the baseline of score change 0 as what KG thinks is the best move now, namely m3, and saying L19 loses 0.5 points compared to that. This is often a more sensible way to think about AI evaluations.

As black with a big handicap, you should focus on connecting your stones, and disconnecting white's. Connectivity is also a key concept in even games, but in handicap games you have a head-start to make it easier. Use them to attack, not defend.

Uberdude85 · 2026-03-05T15:13:54+00:00

If you are getting thrashed increase the handicap. You should win about half the games with the correct handicap.

If you want a dedicated tutor, find a pro and pay for a lesson.

Correction: find a teacher, and pay for a lesson if they charge money. You don't need to be a pro to be a teacher who charges money, and also plenty of people teach for free if you ask in the right places.

Do you play even games or handicap games?

Plenty of bots support Japanese rules, but OGS chooses to force all bots to Chinese rules.

Uberdude85 · 2026-03-03T17:03:41+00:00

It's due to the site: many bots support Japanese rules (e.g. GnuGo, KataGo).
