Go Commentary: Park Junghwan vs Shi Yue – 2013 Samsung Cup – Quarter Finals

This game was played between Shi Yue 9p and Park Junghwan 9p, in the quarter finals of the 2013 Samsung Cup, on October 10, 2013.

Park Junghwan

Park Junghwan is currently ranked #1 in Korea.

He’s very good at fighting, but it’s hard to describe his style of play. That’s because he’s something of an all rounder, so his game is well balanced.

Park won the 24th Fujitsu Cup in 2011, but he hasn’t managed to win any other international titles since then.

He’s in good form these days, and this Samsung Cup is a good chance for him to win again.

Shi Yue is currently ranked #3 in China. He seems to like playing a thick and solid game.

His style of play is kind of defensive, but he doesn’t mind of fighting either.

Shi won the 17th LG Cup, defeating Won Seongjin 9p in the final, in February 2013.

His results in other tournaments haven’t been as impressive since then. However, he’s also been in good shape recently.

En route to the finals

Park Junghwan and Shi Yue defeated Zhou Ruiyang 9p and Ke Jie 3p respectively, in the round of 16. Their head to head record before this game was 2-1 in Shi’s favor.

  1. Thanks for the extremely nice review! I love the facts that you’ve explained so many moves not played!

    Insightful commentary and lots of variations I could never have found. But there is one part of the game keeps puzzling me. Why did white play d2 at move 90, and not f16 or there abouts? I can see that d2 is big pointwise, probably around 20 points, but why not make the exchange in top left first to strengthen whites position there?

    • Younggil An says:

      Good question.
      The move 90 was far bigger than 20 points. If black captures the two stones, black might be able to attack white’s center group. In the actual game, black can’t think of attacking, because his lower left group isn’t strong. So the move 90 helps white’s center group as well, and it’s more important than any other moves at that time.

  3. Thank you so much for your comments, it is very enjoyable to at least understand a bit more what was going on. Despite some mistakes, invisible to me, alas, I think this game is an exciting masterpiece doing justice to both players, it takes two to tango. Do you think komi is too much in white’s favour nowadays, if you cannot find a mistake by black in the first 80 – 90 moves? And white winning many games the last few years, black maybe needing to overstretch to have a chance on winning?

    Kind regards,

    • Younggil An says:

      Thank you for your comment and opinion. I’m not sure about the komi. Majority of top pros still prefer to play black with 6.5 points komi, but they wouldn’t with 7.5 points. I’m not sure if white’s winning more games last few years, but if komi is 5.5 points, I feel it’s a bit too small. 🙂

  4. Could we call the peep at 165 a mistake? I think even Black lets White get 1 point (and play K18 after), the W right side group remains dead. Therefore if W plays K11 B can defend on the left because he doesn’t need to worry about the right.

    • Younggil An says:

      I think so. Black was slightly ahead at the time, but the game seemed to be reversed after the move.

  5. Nice wallpaper or curtains, by the way.

  6. Thanks for this commentary – it was very exciting to follow.

  7. I followed this match by watching Joanne Missingham and Liu Xing (7p)’s commentary; they felt that Shi Yue’s move 92 was okay, but 94 was too greedy and left him in a disadvantageous position.

  8. Wow, I think many fans in China perceive Shi Yue as one of the most aggresive player in China and really good at fighting games. It’s interesting that you have different opinion on his style

    • Younggil An says:

      Oh, maybe I was wrong. Shi Yue’s really good at fighting games, but I feel like he doesn’t fight like Lee Sedol and Gu Li do. It seems like he’s rather specialized at defensive fighting, so I don’t feel his style is aggressive. 🙂

  9. “Park’s moves are razor sharp. On the other hand, Shi’s moves are rather deep and profound.”

    That seems to describe their styles better than in the intro. I’d say Shi’s very imaginative with his attack and defense, kinda like lee sedol. Hopefully they meet in the finals.

  10. I have a question about black 165. Since this peep cost black to lose his right side territory (more than 20 points) while it only allowed approximately an 8 point invasion in white’s corner, should this move be considered a huge mistake? The alternative you suggest at T11 seems like black would be more than 10 points better off.

    • Younggil An says:

      Yes, I agree with you. If black just answered, the game would have still been favorable for black.

  11. Hello! Why do you say there is a one point mistake to play s16 for white there. I mean white shouldn´t play there in any case. Black then doesn´t defend at T11 because he wants to try more and plays “the mistake move” at 017 because he doesn´t want to lose that one point. Since white should always playT12 atari, there isn´t such a lost of one point, so I don´t get the whole point. Could you explain it more, or just that black should play K18 keima right away.

    • Younggil An says:

      Hi goseigen, it’s not simple to explain, but I’ll try.
      Park should have just answered at T11 instead of the move 165, but he wanted to exchange a profitable move in sente, but it was wrong, because white didn’t need to answer to the peep. You can see the move 165 wasn’t right, but if you were playing, it’s hard to judge. And white doesn’t normally atari at the first line to earn one point when there’s a cutting point at S15. As you said, black should have answered at T11, and then K18 keima right away.

  12. I wonder what is more beautiful: the game or the comment. Thank You.

  13. I would like to look at move 39 at N6: is it conceivable?
    I don’t think white can answer N6 at O7, as pulling back at N5 looks tricky for white – though my reading could be wrong here. L:ikewise L6 and M6 I’d answer at N5.
    So I am imagining N6 N5; M5 M6 L6; N7 and then asking with R12, waiting for a chance to play at C14…

  14. Move 107 variation 3: another tesuji that would make a fine medium problem in my humble opinion… nice variation on the “slapping tesuji”. Just a thought…

    • Younggil An says:

      Yes, right. That could be a nice medium problem.

      Thanks for your suggestion. 🙂
