[16:02] sebosai[2k]: Variation: T3

[16:02] KaworuX[7k]: t3

Move 0 + 19

[16:02] marblevolcano[2k]: T2

[16:03] Zuko_1[6k]: Variation: solution

Move 0 + 24

[16:03] marblevolcano[2k]: yes

Move 0 + 18

[16:05] mark5000[7d]: There's a good tactic that captures the white group using shortage of liberties.

Move 0 + 19

[16:05] Akan 101263[4k]: Variation: 4

Move 0 + 18

[16:05] mark5000[7d]: Some of you found it quickly.

Move 0 + 20

[16:05] Demon4x[1k]: r

[16:06] marblevolcano[2k]: R1

[16:06] Demon4x[1k]: R1 *

Move 0 + 21

[16:06] mark5000[7d]: Right

Move 0 + 18

[16:08] FahadAhmed[4k]: was P1 good move by white?

Move 0 + 21

[16:08] mark5000[7d]: Nope.

[16:08] mark5000[7d]: Part of Go is learning to exploit your opponent's mistakes.

Move 0 + 20

[16:09] lillou[7k]: which move would have secured this group?

Move 0 + 18

[16:09] FahadAhmed[4k]: so T2 and then R1 will essentially kill the white group

Move 0 + 18

[16:10] mark5000[7d]: Probably here.

Move 0 + 20

[16:10] mark5000[7d]: Now White can't push r1

[16:10] marblevolcano[2k]: There are options

Move 0 + 20

[16:11] mark5000[7d]: In this other case, Black can exploit the liberties like this.

[16:11] lillou[7k]: but here won't be tow eyes. ?

[16:12] lillou[7k]: r1 now

[16:12] mark5000[7d]: Right. This is dead. T2 is incorrect. It should be S2.

Move 0 + 20

[16:12] mark5000[7d]: Like this.

Move 0 + 20

[16:12] FahadAhmed[4k]: black got good wall on top and can build. so white should tenuki and better destroy black's moyo :D

Move 0 + 20

[16:13] lillou[7k]: but is therea mulltistep ko? when black plays p1

[16:13] mark5000[7d]: Let's move on to the second example.

Move 0 + 20

[16:13] mark5000[7d]: You mean like this?

[16:13] lillou[7k]: yeah

[16:13] lillou[7k]: but, b needs to playn1

Move 0 + 22

[16:13] marblevolcano[2k]: white can just fill

[16:13] lillou[7k]: so. white will ever be able to play p1

[16:13] mark5000[7d]: Why not?

[16:14] lillou[7k]: sure :D

[16:14] mark5000[7d]: Hehe.

Move 0 + 26

[16:14] lillou[7k]: i think i've thought about this several times and always got this but still not sure, if there is a posibillity :D

[16:15] marblevolcano[2k]: B5

[16:15] Green Bones[6k]: c4?

Move 0 + 19

[16:15] FahadAhmed[4k]: P5

Move 0 + 26

[16:16] lillou[7k]: b4

[16:16] twitchclick[10k]: B6

[16:16] mark5000[7d]: This one seems more challenging than the last puzzle.

Move 0 + 27

[16:18] marblevolcano[2k]: oof

Move 0 + 28

[16:19] Kretzsche[4d]: what about c4?

[16:19] LosesALot[5k]: C4 to b5 to b6?

Move 0 + 28

[16:20] marblevolcano[2k]: A5?

Move 0 + 31

[16:20] lillou[7k]: nice tesuij

[16:20] marblevolcano[2k]: oh but b5

Move 0 + 30

[16:25] Kretzsche[4d]: oh i have an idea

[16:25] lillou[7k]: s10?

[16:26] marblevolcano[2k]: T9 I think

[16:26] Green Bones[6k]: o11?

[16:26] marblevolcano[2k]: well... S13 first

[16:26] LosesALot[5k]: S10 is mtug vote

[16:27] mark5000[7d]: o11 is what Black would play if he doesn't see the shortage of liberties problem..

Move 0 + 35

[16:30] marblevolcano[2k]: lol I totally don't feel like a 7k

[16:30] Green Bones[6k]: I see. It's genius

[16:31] FahadAhmed[4k]: that was clever

[16:31] mark5000[7d]: I think it was too

[16:31] mark5000[7d]: That's all I prepared for today's lesson about shortage of liberties. I hope that you can start looking for ways to create shortage of liberties in your own games.

[16:32] lillou[7k]: is the hane on s13 need to be played first?

[16:32] mark5000[7d]: You can often find these situations by smothering your opponent's liberties, and trying to preserve your own liberties.

[16:32] LosesALot[5k]: ty

Move 0 + 32

[16:33] mark5000[7d]: This works also

Move 0 + 35

[16:33] lillou[7k]: show us the squeeze

Move 0 + 35

[16:34] mark5000[7d]: I played s13 to highlight the shortage of liberties.

[16:35] mark5000[7d]: The vital tactic is cut and descend to activate the shortage of liberties.

[16:35] mark5000[7d]: Thanks for watching!

[16:36] mark5000[7d]: Next week's lesson will be on basic 3-4 joseki.

Move 0 + 31

[16:36] FahadAhmed[4k]: Thanks.

Move 0 + 35

[16:36] lillou[7k]: thanks a lot.
