(;GM[1]FF[4]ST[2]RU[Japanese]C[Here is my match from the 2014 Korean Prime Ministers cup with China.  As might be expected I lost without making a real match of it, but there is at least enough content in the game to justify a review.  Yuqing Hu is the number one ranked amateur in China, one of a group of 4 that have been at the top the last few years.]

Instead white can take C, which is vital as it settles the triangled stones and attack black's base.  See the variation in the game for C and then why B doesn't work well.]
