This is the game in which the Russian brother-sister pair of Ilya Shikshin and Svetlana Shikshina, both former European champions, defeated Russia’s Natalia Kovaleva and France’s Fan Hui to take fifth place in the mixed pairs competition. Click here for the sgf game file.
White 8 to 16 are one variation of a popular joseki. This variation and others appeared several times during the week of World Mind Games.
White 38 (the marked stone in diagram 1) was a mistake. The critical issue here is the relative strength of the groups in the center. If the white pair had played as shown in diagram 2, their own center group would have had the upper hand, and they would then have been free to deal with the loose black framework on the right side.
If black had captured white 98, the white group in the center would have been in serious trouble. Apparently Ilya decided that invading the bottom right corner first would be a safer way to win, but this is not necessarily true. If white had played 123 in sente before black did so, then given the same continuation on the rest of the board, the final margin would have been only half a point. As it was, black won by 1-3/4 stones, or 2-1/2 points.
