(;B[mc]LB[oe:A]LB[pe:B]C[Hi! We're going to look at the one-space low pincer with the 3-4 point. Previously, we studied the high approach. The low approach is often played as well. This one-space pincer is Black's most severe move. In this situation, playing elsewhere isn't a good idea.

jillgoodgal: pincer!
Lapshin Fedor: hi
clackie: hello!
Muzungu: hi. From move 0: R16 P17 N17 
mark5000: This is a text lecture. There's no audio.
clackie: I member the high approach joseki, been using it in my games!
mark5000: If possible, you need to respond to Black's pincer attack.
mark5000: Let's see White's possible answers.
mark5000: Today, we looked at two moves for answering the one-space pincer.
mark5000: That's all I planned to talk about.
mark5000: Any questions?
ZakariaBouguira: i really found it very interesting Thank you
jillgoodgal: thank you
Аlрhа - 1 5 2: While playing at 13x13 board, I often see opponents play r13 as B's 2nd move.

;B[ph]C[Black will extend again. Black's making territory along the fourth line. You may think these exchanges are bad for White.

clackie: I do
]
;W[jc]C[But White does get some profit by attacking this black stone. Players tend to value this joseki differently. Kyu players often feel that Black is better because of the fourth-line territory. Players around 1-2 dan almost universally think that White is better, since they are learning the value of influence and attacking. In truth, this sequence is even and is a kind of joseki. To play it, you have to be able to profit enough from the attack, so I don't recommend this for kyu players.

clackie: black is safer, you still have to make sure the black stone stays dead
latashia: How about Q12 instead of P14?
Muzungu: Thank you very much

;B[pc]C[Black should attach here,]

;B[ic]C[Since these two stones are weak now, Black should reinforce his group like this. This isn't the most basic joseki for the one-space low pincer. Actually, it's quite difficult. But if you learn this sequence, it will help you at some point. If you think the one-space jump is too complicated, there's an easier way.

clackie: I'm starting to question what white is getting out of this?
mark5000: A reasonably safe center group and potential development on the right side
mark5000: The upper Black group is also not completely secure.
jillgoodgal: if white has a stone around D16 it looks good for white
mark5000: Yes
mark5000: I'm going to show you an easier way though.

ZakariaBouguira: P13 ?
clackie: p13 would get cut to pieces I think
