Go Commentary: Lee Sedol vs Gu Li – 3rd BC Card Cup Game 5

This is a commentary of the fifth and final game from the finals of the 3rd BC Card Cup, between Lee Sedol 9p and Gu Li 9p.

Gu Li (9 dan - left) vs Lee Sedol (9 dan) in the final of the 3rd BC Card Cup

Lee Sedol took black, and Gu Li played for white.

In game four, Lee was leading, but Gu Li reversed the game in a spectacular upset. Because of that, people expected Gu to be in good shape for this final game.

This game had less fighting than the other games in the series, so in some ways it wasn’t as exciting. Even so, it was a great game, which was more subtle and delicate than their earlier matches.

Lee Sedol won this game, which meant he won the BC Card Cup for the second year in a row. This game was played on April 28, 2011.

    I heard a amateur 8 dan review this game on KGS, and from what he said it seemed like white should have payed Q1 instead of N10 because Q1 area was sort of double sente. Is that at all accurate?

    • David Ormerod says:

      That sounds a bit funny to me SC. From my analysis, Q1 isn’t really a big enough threat to be sente at this point.

      If white plays N10 at Q1, black could answer at N10 immediately or at R1. R1 improves black’s position in the corner slightly, after which white hasn’t defended anything yet (black can still play P1). If white wants to continue with this plan, white now has to connect at P1, but black will then take the pivot point at N10. The way I see it, white can’t cut off black’s corner group in sente (or with a good double threat to get into the top right area) so connecting and defending the corner are miai for black.

      If black plays N10 instead of R1, white has a stronger followup at S2 (black will respond with S7), but doesn’t get a second chance to play N10. The miai situation is still more or less the same.

      Another way of thinking about this is, if Q1 was really so sente, white might be able to capture at Q1 in sente in the actual game. The board has changed slightly, so this reasoning doesn’t always work, but it’s still worth reflecting on this.
