From child prodigy to world number three right before our eyes: GM Gregory Kaidanov, former coach of GM Fabiano Caruana, discusses his student's one childhood weakness and the long process of overcoming it. Caruana's memory improvements have led to many great wins, including this one from the 2010 Olympiad. He sacs his queen against a strong GM and wins quickly. How quickly? It only took him five minutes! Kaidanov takes a bit longer in explaining this pleasing brilliancy.
