This was the first game of the 17th China Korea Tengen, between Chen Yaoye 9p and Park Younghun 9p.

Chen Yaoye is currently ranked #1 in China, and he’s already won this China Korea Tengen three times.

He’s held the Tianyuan (Chinese Tengen) title for five years in a row now.

Over the last two years, Chen defeated Choi Cheolhan 9p in this mini title match, with a score of 2-0 both times.

If he won this time, he’d make it three in a row.

Chen also won the 9th Chunlan Cup this year, against Lee Sedol 9p, and he’s currently regarded one of the strongest players in the world.

He likes to play thick and solid games, but, actually, he’s very good at fighting too. His reading is sharp and accurate, and he rarely makes mistakes.

Park Younghun

On the other hand, Park Younghun 9p is ranked #6 in Korea.

He was given the nickname ‘Little Prince’ when he won the 6th Chunwon (Korean Tengen) title as a 2p.

He was also called ‘Little Lee Changho’ because he’s very good at the endgame and counting – which was Lee Changho’s specialty too.

Recently, Park’s been playing more of an active and fighting game, compared to before, and it seems like he’s trying to change his serene style to become more of a fighter.

Qualifying for the China Korea Tengen

Chen defeated Gu Lingyi 5p 2-0, in the final of the Tianyuan, to qualify for this mini title match.

Meanwhile, Park bested Choi Cheolhan 9p 2-1, in the final of the Chunwon.

Park and Chen first played one another in 2006, at the 6th Chunlan Cup, and Chen won.

However, Park beat Chen at the 8th Nongshim Cup (2006), and at the 14th LG Cup (2009).

Those games were quite a while ago though.

Let’s have a look at the first game from the 17th China Korea Tengen match.

  1. Wow thanks for the commentary Mr. Younggil. These are two of my favorite players!

  2. Thank you for this commentary, Mr. Younggil!
    I love this kind of sacrifice strategies .

    • David Ormerod says:

      Me too. I would have resigned as white in that game 🙂

      Even losing by 1.5 was amazing!

      • … and who knows what would have happened had White not made the endgame mistake @ 128.

        • Would still be a close game? If go would be playable without mistake we wouldn’t play it, is there a game you can play without making mistakes?

  3. Fascinating game and excellent review, thanks!

  4. thanks for the wonderful review, Mr Younggil.

  5. Thanks for the review and great insight!

  6. Could someone send me a glossary of GO terms so that I can follow the commentaries? That would be a great help for a new player.

  7. Awsome comment!
    Would someone please describe the value of move 286? wouldn’t it be better for W to play M-15?

    • Younggil An says:

      That’s a good question.
      Under the Chinese rules, the neutral point is also one point. M15 and A12 are miai, so white didn’t play at M15, but played at 286 which was a neutral point first.

  8. Now I see!
    Thank you, Mr. Younggil!

  9. At move 46 you suggested the atari at O5 as more usual shape.

    I was wondering though after the line to O10 how white can cope with the (crude?) play at P9. White seems to get split if P10 – black hacks his way out with Q9 O8 P8 and I don’t find a nice way for white – sacrifices seem too generous. Playing at O8 instead of P10 still seems a problem on the cut. Am I missing something?

    • Younggil An says:

      That’s a good question.
      If black plays at P9, white’d block at P10, B Q9, W O8, B P8, W P7, B O7, W O6, B O9, W N9, B N8, and White can atari at N7. It’s a ko, but black doesn’t have any big ko threats. In addition, White can connect at Q13 after white wins the ko. That’s why white doesn’t need to worry about that.
