Go Commentary: Gu Li vs Iyama Yuta – 1st Bosai Cup

This game was the final of the Bosai Cup between Gu Li 9p and Iyama Yuta 9p. Both players defeated Lee Sedol 9p before this game.

Iyama played this game wonderfully. White 112 was the winning move. Iyama’s endgame was perfect, and Gu didn’t get any chances afterwards.

This game should be one of Iyama’s best games, I’m sure.

    Thank you very much, iyama play very well

  3. The commentary says, of White 14, “This is one of Iyama’s favourite moves. A or B is more common instead.”Out of 176 games in the rather large and up-to-date GoGoD database Iyama has played this move just once. There may be some other games but it still seems hard to justify calling it a favourite.
    If the reference is not to this position but to the high distant White approach in general, there are just 7 examples by Iyama compared to 63 high close approaches.

    Also, according to the database, B is common but A seems very rare.

    May I ask what I have missed?

      Good question!
      I asked one of my Korean pro friends to get more information of this game, and he said that the approach is Iyama’s favourite. Actually, 7 out of 63 is quite a big number compare to other top players’, and also Iyama might have played that approach at the preliminary matches or practice games In Korea.
      In my opinion, there’re some things you can’t judge from that sort of data base in Go.  

      For the second question, I might be wrong about A. W normally plays at A, and when B answers at B, then W plays at A. It could be my mistake. 
      Thank you for your attention and questions. I learned a lot from them. :D

      Would you mind being a little clearer about the local search you did? For that one I can’t replicate your results.

    Thanks for the commentary.

    This game inspired me immensely. Now, seeing their mistakes and why their moves were right is very enlightening :)
