Rising young Japanese pro Shibano Toramaru (18 years old, recently promoted to 7p) made a rather spectacular sacrifice of 32 stones (I presume rather than a misread!) against veteran Cho Chikun (don't know the event, maybe someone can read Korean of title in first pic) when he didn't live with his group but set up a cut against a surrounding group and let it become a ko. He lost the ko but his ko threat made a big profit and solidified the moyo he had built up with the outside sente moves during the semeai. Shibano won by 6.5 in the end even with Cho living at the lower left and sneaking in the middle a bit.

Shibano was white and pushed below instead of living. I suppose if Cho answers it might be a little bit good exchange before living, or was it more of bait for this elaborate trap?

It's the tournament to get into the 43rd meijin league.

Here is the bracket

Thanks, here in English: https://gotoeveryone.k2ss.info/jp/meijin/ (click 43rd at top). So he has to beat probably Ichiriki to get one of the 3 spots.

Thanks, I was searching for Kin's site but lost track of it.

Also interesting note, Koyama Kuuya 3d beat Sakai Hideyuki 8d in the preliminary tournament. Sakai was dropped out of the league this year and is now out in the first round.

Koyama and Ichiriki are playing now, it's a pretty exciting game.

Update: Ichiriki won as expected, but I thought Koyama gave him a good run for his money.

It's a shame Shibano and Ichiriki are in the same bracket, I'd like to see them both progress to the Meijin league.

Not so surprising. Sakai was very good several years ago, but dropped off very quickly.

They just decided to hold a challenger decision match early ;). Seriously, it's also a bit unfortunate that you have Kyo Kagen and Yu Zhengqi in the same bracket.
