Move 0 + 2

May 26, 2019

[21:28] 💖 KoBa 💖[1d]: ooh are you gonna go thru the modern variations as well?

[21:28] mark5000[8d]: I'll give it a few more minutes.

[21:28] mark5000[8d]: Yes, hopefully.

[21:28] Icedrinker[6k]: Hello everyone! I am lucky to find it before it started.

[21:28] mark5000[8d]: The lecture is aimed at double digit kyu players, but we can use time at the end to discuss other sequences.

[21:28] 💖 KoBa 💖[1d]: great! i'm exited to see whays coming ^__^

[21:31] Sean R[13k]: That announcement certainly helped :p

[21:31] humblestick[17k]: excited too...

[21:31] snakesss[6k]: Variation: 1

[21:31] mark5000[8d]: Haha, yes. We'll start very soon

[21:32] snakesss[6k]: misclick sry - wow 30+ people

[21:32] Sean R[13k]: :p

Move 0 + 3

[21:32] Ewen[1d]: hello

[21:32] mark5000[8d]: Hello. Thanks so much for joining us.

[21:32] mark5000[8d]: Of course, you can leave when you wish...

Move 0 + 2

[21:32] Stephen Hubbard[8k]: Hi

Move 0 + 3

[21:33] simpleTom[4k]: Hey, thank you for doing this lectures :)

[21:33] mark5000[8d]: Note: this is a text-based lecture. There's no discord or audio or video or anything.

[21:33] mark5000[8d]: If you're here, you're good.

Move 0 + 4

[21:33] Icedrinker[6k]: This attachment is bad if there's no Black stones around K16, so far as I know

Move 0 + 5

[21:34] mark5000[8d]: That's partially true.

[21:34] mark5000[8d]: Other moves are played more, but the difference is not big. Maybe 1 or 2 stones worse than another option.

[21:35] mark5000[8d]: Attaching is for a moyo or influence strategy, as you will see.

[21:35] Ewen[1d]: maybe play r15 instead ?

[21:35] Ewen[1d]: i see this one more often ?

[21:35] mark5000[8d]: Yes, r15 is the other good answer. We'll see it later.

[21:35] Ewen[1d]: oh sorry for spoiling

[21:35] mark5000[8d]: :)

[21:36] mark5000[8d]: Does anyone know the options here?

[21:36] Ewen[1d]: i think white should push

[21:36] Goldenrod[4k]: q10?

[21:36] Luiskaotsa[3k]: R15 I think

Move 0 + 8

[21:36] Icedrinker[6k]: Variation: This?

Move 0 + 5

[21:36] mark5000[8d]: r15 is one.

[21:36] Wugabuga[3d]: S15

[21:36] mark5000[8d]: Icedrinker, spoiler alert :)

[21:36] martin3141[5d]: r16?

[21:37] redirodion[11k]: can I just play P13?

[21:37] mark5000[8d]: r16 is the other move that's really good.

[21:37] Icedrinker[6k]: I'm sorry xD

[21:37] mark5000[8d]: s15 is kind of special purpose.

[21:37] AdamR[2d]: 3-3 is always an option, right? :D

[21:37] mark5000[8d]: q10... you have to be careful about vital points. r15 is a vital point. You don't want to give Black a big corner and a tiger's mouth shape.

[21:37] DROmedary[5d]: I've never seen humans play S15 but I saw a bot prefer it the other day in review and was surprised

[21:38] mark5000[8d]: r17 is the last possibility. So really 4 choices. And 2 are better than the others.

Move 0 + 15

[21:39] 💖 KoBa 💖[1d]: Variation: it's pretty good move espesially in handicap games

Move 0 + 10

[21:39] redirodion[11k]: I'm worried

[21:39] Icedrinker[6k]: I would be more worried about White here

[21:40] martin3141[5d]: what is the best way to play now?

Move 0 + 15

[21:41] mark5000[8d]: Friendly reminder, if the moves don't make sense with my text, try hitting the sync button.

Move 0 + 12

[21:41] martin3141[5d]: ah oh sorry

Move 0 + 11

[21:44] RyukBaduk[7k]: The myth, the legend, he is mark

Move 0 + 10

[21:45] Luiskaotsa[3k]: I think I've seen the same pattern one line higher as well?

Move 0 + 11

[21:46] mark5000[8d]: It's possible.

Move 0 + 6

[21:46] snakesss[6k]: i'm thinking some ddks might wonder if this is an even exchange sicne black is so strong and white small and with aji but white approached black's corner and ended the sequence with sente

[21:47] mark5000[8d]: Yeah, it's not quite as good as other joseki options, but sometimes it is.

Move 0 + 9

[21:47] porygon[9k]: oh hi mark

Move 0 + 8

[21:47] RyukBaduk[7k]: W k17

Move 0 + 9

[21:47] 💖 KoBa 💖[1d]: white does get a solid position in the side of where he did approach in the first place, so if w plays r14 we could say that w got what he wanted to

[21:47] martin3141[5d]: I rarely see the attachment though. Is it good for white?

[21:48] mark5000[8d]: It's slightly good for White, in isolation.

[21:49] humblestick[17k]: from a raw beginner why not p p17?

Move 0 + 10

[21:49] neptix[4k]: But it makes a nice wall, if you can combine it, yes?

Move 0 + 11

[21:49] martin3141[5d]: I think these patterns are popular when white has a stone at o17

Move 0 + 11

[21:49] Wugabuga[3d]: Sometimes I see White R9 instead of R10, is it too greedy ?

[21:50] mark5000[8d]: It's a bit greedy, yeah. We'll discuss later.

[21:50] Wugabuga[3d]: Alright

Move 0 + 10

[21:50] mark5000[8d]: Actually, now is good.

[21:51] martin3141[5d]: I should probably shut up :X

[21:51] snakesss[6k]: so the attachment at r16 means a little bit more of the corner for white but sente for black

Move 0 + 14

[21:51] RyukBaduk[7k]: Why not 4th line

Move 0 + 10

[21:56] Bjondro[4k]: s13?

Move 0 + 14

[21:57] RyukBaduk[7k]: Variation: 2

[21:57] RyukBaduk[7k]: Pow

Move 0 + 10

[21:58] mark5000[8d]: :)

Move 0 + 18

[21:59] RyukBaduk[7k]: Variation: 3

Move 0 + 10

[22:00] mark5000[8d]: Yes

Move 0 + 13

[22:01] 💖 KoBa 💖[1d]: Variation: or tenuki after r17, if ythere is somehing more urgent to play?

Move 0 + 14

[22:02] mark5000[8d]: Tenuki wouldn't be good in my opinion. It's a big corner, and it's hard to imagine a tenuki worth that much.

[22:02] mark5000[8d]: You also lose cutting options later.

[22:02] mark5000[8d]: Which we'll see soon.

Move 0 + 15

[22:02] Paraparam[2k]: Variation: Is it good to secure the corner like this or is it better to spend the move elsewhere?

Move 0 + 14

[22:02] 💖 KoBa 💖[1d]: i see i see

Move 0 + 19

[22:06] neptix[4k]: N13?

[22:08] mark5000[8d]: n13 would be an interesting idea. Generally, however, if a simple move is already good for you, you don't need to think hard about other options.

Move 0 + 15

[22:08] neptix[4k]: heh, fair enough

Move 0 + 21

[22:09] martin3141[5d]: this is possible if black is stronger in the middle

Move 0 + 24

[22:10] Wugabuga[3d]: If Black is strong around, maybe black could double hane and try to kill x)

[22:10] martin3141[5d]: yes

Move 0 + 23

[22:10] Wugabuga[3d]: :)

Move 0 + 9

[22:13] mark5000[8d]: I think I saw this move mentioned earlier?

Move 0 + 5

[22:18] Hakmans[2k]: Sure!

Move 0 + 10

[22:22] martin3141[5d]: what about r13? That would seem natural to me.

Move 0 + 3

[22:26] mark5000[8d]: That's all the material I had planned for this lecture.

[22:27] mark5000[8d]: Are there any questions about any part of it, or maybe something not covered that you want to discuss?

[22:28] mark5000[8d]: This lecture will be added to my existing lecture series here: becoming 9-kyu-a-series-for-beginners

Move 0 + 13

[22:28] martin3141[5d]: after the black attachment, I heard that white can go into the corner immediately

Move 0 + 3

[22:28] mark5000[8d]: Thanks for watching. :)

Move 0 + 13

[22:28] 💖 KoBa 💖[1d]: thank you for making this!

Move 0 + 13

[22:28] neptix[4k]: Thanks for the lectures!

Move 0 + 15

[22:28] Hakmans[2k]: Thanks!

Move 0 + 4

[22:29] martin3141[5d]: r15

[22:29] mark5000[8d]: martin, you mean like this?

[22:29] martin3141[5d]: no, with r15

Move 0 + 4

[22:29] mark5000[8d]: Ah, right.

[22:29] mark5000[8d]: This is a new AI-inspired move.

[22:30] mark5000[8d]: To me, q13 is by far the most natural move, because it shorts liberties and starts a battle of surrounding, which is what Go is.

[22:30] mark5000[8d]: Second would be a wedge at q15, which wasn't discussed.

[22:30] mark5000[8d]: Then my third choice would be here.

[22:31] mark5000[8d]: But AI likes it, so I may have to reevaluate my preferences.

Move 0 + 8

[22:31] martin3141[5d]: probably white s17

Move 0 + 10

[22:32] martin3141[5d]: oh

Move 0 + 11

[22:34] martin3141[5d]: very interesting, thank you

Move 0 + 3

[22:35] mark5000[8d]: Ok, thank you everyone. Bye for now.

[22:35] mark5000[8d]: Next lecture is hopefully next week around the same time.
