Move 0 + 29

[16:03] Assai[7k]: t12

[16:03] deterdettol[16k]: Isn't this shape called golden chicken standing on one leg?

[16:03] deterdettol[16k]: 金鸡独立?

[16:04] snakesss[4k]: "there will be a throwin tesuji"

[16:04] mark5000[6d]: I'm not sure of the Chinese name, actually.

[16:04] deterdettol[16k]: senseis: GoldenChickenStandingOnOneLeg

Move 0 + 31

[16:05] snakesss[4k]: rip w

[16:05] lillou[5k]: only one eye

[16:05] snakesss[4k]: haxxx

Move 0 + 28

[16:10] scotto[3k]: m16

Move 0 + 31

[16:10] mark5000[6d]: Then what?

[16:11] Natacha_Go[5k]: R19 ?

Move 0 + 31

[16:12] snakesss[4k]: p19 perhaps

Move 0 + 28

[16:13] Natacha_Go[5k]: I miscalculated ;)

[16:13] FeoDoT[6k]: O19

Move 0 + 31

[16:14] Natacha_Go[5k]: Yes O19 seems interesting

[16:14] mark5000[6d]: What next?

[16:14] Natacha_Go[5k]: hmm... still the same problem

Move 0 + 30

[16:14] lillou[5k]: it's done^^

Move 0 + 30

[16:14] snakesss[4k]: just descend then

Move 0 + 30

[16:14] snakesss[4k]: yup this

[16:15] snakesss[4k]: only one left basically xD

Move 0 + 31

[16:15] June144[1k]: P19

Move 0 + 28

[16:15] mark5000[6d]: :)

Move 0 + 34

[16:18] lillou[5k]: :)

Move 0 + 28

[16:18] mark5000[6d]: Let's see it again.

[16:18] mark5000[6d]: This tesuji is practical and useful

Move 0 + 30

[16:19] mark5000[6d]: In this case, the diagonal on the first line is good.

Move 0 + 32

[16:20] mark5000[6d]: Remember this combination!

[16:20] mark5000[6d]: I've never heard a proverb like "There's a tesuji on the first line."

[16:20] mark5000[6d]: In my opinion, however, it could be added as a new proberb.

[16:20] Natacha_Go[5k]: =)

[16:21] mark5000[6d]: I hope you'll be able to use this knowledge and look for first-line tesujis in your own games.

[16:21] Natacha_Go[5k]: Thx a lot !

[16:21] mark5000[6d]: That's all I had planned for today's lecture. Any questions?

Move 0 + 40

[16:21] deterdettol[16k]: Yes:

[16:21] deterdettol[16k]: Actually no, oops

[16:21] deterdettol[16k]: Thank you!

Move 0 + 32

[16:21] lillou[5k]: thanks

[16:22] Natacha_Go[5k]: Well... not exactly the subject but...

[16:22] snakesss[4k]: lets see if we see lots of 25kyu games with random first line tesujis xD

[16:22] Natacha_Go[5k]: here you can kill will S17 or R19

[16:22] snakesss[4k]: first line moves are like broken clocks, they are correct twice a day

[16:23] Natacha_Go[5k]: what is the best move to limit the possibilites of ko

[16:23] Natacha_Go[5k]: ?

[16:23] Natacha_Go[5k]: I'l not sur to be clear

[16:23] mark5000[6d]: Where do you see a ko?

Move 0 + 33

[16:23] FeoDoT[6k]: Variation: if the Black stretches?

Move 0 + 32

[16:23] mark5000[6d]: And snakesss, the trick is to see when there is a tesuji and when there is not.

[16:23] snakesss[4k]: both atariing moves for black would be selfataris

[16:23] snakesss[4k]: not for white though

Move 0 + 33

[16:24] Natacha_Go[5k]: I don' see any ko. I'm mean if afterwards there is a lko in the game

Move 0 + 34

[16:24] mark5000[6d]: Just connect here, I think.

[16:24] mark5000[6d]: There's a liberty shortage here, too.

Move 0 + 34

[16:24] deterdettol[16k]: IF Natacha suggests wR19,

[16:24] deterdettol[16k]: Variation: Then this is a ko?

Move 0 + 31

[16:24] Natacha_Go[5k]: I presume the idea is to minimize the possibilities of ko answers

Move 0 + 32

[16:24] snakesss[4k]: when they do m19, yo gotta take a liberty

Move 0 + 32

[16:24] mark5000[6d]: Correct.

[16:24] snakesss[4k]: cuz after m19, they can atari with o19

[16:25] snakesss[4k]: without selfatariing

[16:25] mark5000[6d]: Living is much cleaner than ko, even if you are the ko master.

Move 0 + 34

[16:25] deterdettol[16k]: But aren't ko fights good? If you can win?

Move 0 + 32

[16:25] snakesss[4k]: next: ko? mark? :)

[16:25] mark5000[6d]: No, Not at all. Winning a ko just means your opponent's free move wasn't as big as the ko.

[16:26] mark5000[6d]: Your opponent still got a free move, however.

[16:26] mark5000[6d]: It's better to live and not allow any free moves.

Move 0 + 34

[16:26] deterdettol[16k]: Ah...

Move 0 + 32

[16:26] Natacha_Go[5k]: Well, here maybe it is not a good example.

[16:26] mark5000[6d]: If you grant your opponent two free moves in a game, there's one stone handicap right there. It's the difference between 10k and 9k.

[16:27] Natacha_Go[5k]: What I try to say is...

Move 0 + 34

[16:27] deterdettol[16k]: mark5000: I'll make sure to remember that exact line...

Move 0 + 32

[16:27] snakesss[4k]: who interesting way of putting it

[16:27] snakesss[4k]: whoa*

[16:27] Natacha_Go[5k]: when I have different possibilities to kill a group sometimes I have a doubt in the choice

[16:27] snakesss[4k]: i would love a lecture on ko

Move 0 + 34

[16:27] deterdettol[16k]: +1

Move 0 + 42

[16:27] lillou[5k]: Variation: do you mean this?

Move 0 + 32

[16:28] mark5000[6d]: Sounds good. Making ko will be next week's lecture.

Move 0 + 43

[16:28] Natacha_Go[5k]: to not give another move if some ko occurs afterwards in the game

[16:28] mark5000[6d]: Feel free to construct a position that describes what your question is about.

Move 0 + 32

[16:29] Natacha_Go[5k]: OK. next time I'll try to prepare something

[16:29] mark5000[6d]: Great.

[16:30] mark5000[6d]: This lecture was part of my Saturday lecture series on becoming 9 kyu.

[16:30] mark5000[6d]: Find past lectures here: becoming 9-kyu-a-series-for-beginners

[16:33] deterdettol[16k]: Sweet :)

[16:33] Natacha_Go[5k]: Yes lillou

Move 0 + 37

[16:34] FeoDoT[6k]: Variation: if continue like this

Move 0 + 32

[16:35] lillou[5k]: you were asking which move is better to capture after the attachment and black going to the first line weren't you

Move 0 + 40

[16:36] lillou[5k]: Variation: goes to ko

Move 0 + 34

[16:36] lillou[5k]: Variation: seems clean

Move 0 + 36

[16:37] mark5000[6d]: You missed this.

[16:38] mark5000[6d]: Same liberty shortage.

Move 0 + 40

[16:39] lillou[5k]: yeah

[16:39] lillou[5k]: i found it after thinking about this again

[16:39] lillou[5k]: but with the other variation black got one moves less on the outside?

[16:40] lillou[5k]: nono

[16:40] lillou[5k]: just because in my variation black did take away one liberty of his own

Move 0 + 32

[16:44] FeoDoT[6k]: thanks, Mark!

Move 0 + 19
