The remarkably talented Harmony Zhu
by Frederic Friedel
1/20/2014 – "Did you see the Canadian girl?" Garry Kasparov said to us. "Very impressive!". He was in Al Ain, paying a visit to the World Youth Championship, where a seven-year-old was dominating the under eight group. We check her out and found that Harmony Zhu is not just a great chess player. She is extremely talented in a completely different field – hint: nomen est omen... You will never guess!
