ThiGar [3k\]: Good afternoon :-)

;B[fc]C[NHEN [5k\]: hello !

;W[oc]
;B[lc]C[RaduStefan [1d\]: BigBadWolf against a 9P? Sweet
RaduStefan [1d\]: Mr. scribe, any youtube live stream?
ligo [4k\]: video for board 1 on yt
USGO2 [-\]: Not yet anounced. Probably will be something.
wolokom [5k\]: time?
Nils [3d\]: two 9P in the tournament? wow
Nils [3d\]: how old is ahn dalhoon?

;W[md]C[USGO1 [-\]: Video streaming feeds: https://twitch.tv/usgoweb  https://www.youtube.com/c/USGOweb 
ctdogpdf: only monsters in this competition
RaduStefan [1d\]: I've never seen this opening.
]
;B[ld]
;W[le]C[ctdogpdf: might be some alphago stuff
RaduStefan [1d\]: is this still even?
ctdogpdf: they are playing a joseki right ?
USGO1 [-\]: results and pairings: http://www.usgo.org/tournaments/crosstab/band-matrix/182
ctdogpdf: n16 is considered bad
ctdogpdf: but theres a variation
ctdogpdf: b can l15 or n17
RaduStefan [1d\]: N16 looks bad. In my opinion. But I'm not sure. Any strong demi-go-god cares to comment?
ctdogpdf: i prefer the l16 variation
ctdogpdf: b can get strong on both sides
ctdogpdf: and w has aji to care about
ctdogpdf: unless w has a trick up his sleeve
ctdogpdf: l15 variation
r0n1n [3d\]: it feels natural to try and push ahead, may it be into the center
]
;B[mc]C[ctdogpdf: so o16 l15
ctdogpdf: hane then cut ?
r0n1n [3d\]: maybe nobi instead of hane ?
r0n1n [3d\]: cut looks annoying for the shape
ctdogpdf: yeah right
ctdogpdf: i just want things to get messy
ctdogpdf: games are more interesting that way ;)

;W[rd]C[ctdogpdf: nice b ponnuki + sente
ctdogpdf: c14
ctdogpdf: then get sente again ?
]
;B[cf]C[ctdogpdf: f16
RaduStefan [1d\]: ctdogpdf, let's not monopolize the chat window. You should let high-dans comment. :) I am actually curious to hear some high-dan opinions regarding the exchange in the upper right.
ctdogpdf: w sacced two stones to get the corner, compared to the direct q15 variation
ctdogpdf: m17 feels a bit useless too
ctdogpdf: but b got sente
ctdogpdf: which is big in the beginning
ctdogpdf: theres still a bit of aji in the corner btw
ctdogpdf: so at least some ko threats are there
ctdogpdf: and w cant really expect to expend his corner efficiently on the right side
ctdogpdf: point wise with komi, w already 20 points
ctdogpdf: b still has to cash on

;W[fd]
;B[gd]
;W[ec]
;B[fe]
;W[ed]C[ctdogpdf: another corner for w in sente
ctdogpdf: trying to get a territorial game
ctdogpdf: but on r5 on his next move
RaduStefan [1d\]: ctdogpdf, how old are you?
ctdogpdf: the same as the captain

;W[ge]
;B[eb]
;W[ff]C[ctdogpdf: this is a high level game id like people to comment 
]
;B[cc]C[ctdogpdf: looks like this variation is good for b
]
;W[cd]
;B[bd]C[Penfold [5k\]: w has the driving tesuji to capture f15 or neutralize c14
ctdogpdf: b17 ?
Penfold [5k\]: because b17 b18 c18 ?

Isokasan [6k\]: yes
sophist: professional, yes.
gocool [6k\]: thank you guys
ThiGar [3k\]: anybody, how many north american professionals today?
Penfold [5k\]: 7 from the US, 2 from Canada

jlm [2k\]: Q4 interesting...never would have thought of it
jlm [2k\]: W obviously wants outside
Herod [-\]: aiming at p3 seems natural after m3
sophist: I would play at O3
Shahrazad [4d\]: White already feels way behind
gocool [6k\]: Q2?
sophist: Andy, both his look and his play style, reminds me Go Seigen.
sophist: White is behind? Really?
USGO2 [-\]: White has 53 minutes main time remaining; Black has 33
sophist: Andy rarely plays slower than his opponents :-)

]
;W[pj]
;B[nn]C[Uberdude [1d?\]: d12 for g11 seems like a good exchange for black to me, ocmpare to if w got d12
Uberdude [1d?\]: if white tenuki feared attack where? g13?
Penfold [5k\]: I think g11 also helps the bottom a little too
Uberdude [1d?\]: yeah but with d12 w dreams of attacking d7 pretty much gone
]
;W[eo]C[Uberdude [1d?\]: if white got d12, then later some sabaki with h3 stone can have attack threat
gocool [6k\]: jie?

;W[oh]C[Uberdude [1d?\]: m8 is inefficient now, and w's reduction didn't make many points
Uberdude [1d?\]: dont forget r18 clamp

;B[qk]
;W[ri]C[gocool [6k\]: E5 is not a good move
]
;B[ol]
;W[pk]C[Penfold [5k\]: It consolidated whites corner in sente, but solidified f3 and d6
gocool [6k\]: is not a good exchange
ThiGar [3k\]: can w reduce the left side?
Penfold [5k\]: That seems okay to me as black was already strong here.
