20th Nongshim Cup

Next up for Park tomorrow is Dang Yifei, who had a win streak of 5 games last year (Shin Minjun, Ichirki Ryo, Kim Myeonghoon, Iyama Yuta, Shin Jinseo, before losing by half a point to Kim Jiseok). I'd bet on Park: Dang's performance last year was exceptional for his relatively low rating (goratings #38, almost 200 Elo lower than Park), Park leads 3-0 in head-to-head, and goratings gives Park 76%, mamumamu 77%. But Dang surprised before, particularly against Shin Jinseo (but he lacked experience on the big stage, unlike Park).

@Uberdude: For the game Park vs Iyama. Can you help to continue the Lizzie analysis to see where did W collapse? The game looks still well balanced to me until W invade the low right corner. It seems Iyama overcomplicated the game and it backfired. Or was him already short in points before?

[Uberdude]

Yes, the lower right from 152 was Iyama's big mistake and where Park got the decisive advantage. LZ suggests s5 placement instead to get a little yose with s8 and o6 sente and then just n2 reduce from outside. Also earlier at move 128 it thought directly making classic good shape m8 defence was better than making r8 exchange seeing as black gets to s7 anyway. Here's the game with variations from Fox plus my LZ exploring.

Today's game with Dang so far, Park (white) was building up a nice lead (b8 attach as LZ suggestion to his solid f5 is amazing), but the f7 defence was overly conservative and Dang found a nice forcing sequence to build up outside strength in sente and it's closer now.

Update: looks like Park might lose this, if Dang plays accurately. He tried attacking but his own group is weak too...
And I jinxed it, as soon as I posted Dang made a -40% mistake according to LZ 205, 155 hane outside instead of cut looks good style, but means white can capture f14 in a way giving blak 2 cuts, and has implications for c14 big yose too.

Looks like Dang Yifei B+1.5

It is amazing - the development this year was exactly the same as two years ago.

Japanese player won the first game, followed by Fan Tingyu's 7 consecutive wins, followed by Park Junghwan's 2 wins...

And same winning margin in final game from the not-top-10-but-can-still-beat-anyone-on-a-good-day-(and-there's-loads-of-them) Chinese player!
