In the seventh round of the 2011 World Junior Chess Championship in Chennai, India, 16-year-old Vidit Santosh Gujrathi, with the black pieces, is looking for his fifth point while facing off against Grandmaster Aleksandr Shimanov. After a lively Ragozin defense, Gujrathi has successfully built up a considerable positional advantage to where he can now launch a lethal attack against white’s king, using every resource at his disposal. However, he must not delay, or else Shimanov could quickly consolidate and defend himself. Can you find the mate-in-six in this position, and secure Gujrathi’s victory? (Black to move.)
