  6. This game is unbelievably complicated. Great commentary as always.

  7. Thanks for the commentary!

    I cant figure out why white played R6 (move 78) and not S6. In the game white had to come back to protect the cut…

    Happy holidays!

      That’s a good question!
      If W plays at S6, B’d atari at R6, W S5, B S7, and W has to live in the corner, and the result is not satisfactory for W.
      Even though W spent one more move here in the actual game, Choi might have thought it was worth playing one more move.

  8. Your game commentaries are wonderful, informative, and entertaining. It’s a whole package. Thank you!
