And Genghis pwns all. There's a bit in LOCH where Genghis presents a strategic conundrum to Ogedei, Tolui and Guo Jing, and asks them for their opinion. Ogedei and Tolui both suggests solutions that deal with the enemy force in some fashion, but are unsatisfactory in terms of strategic objectives gained or cost in casualties. Guo Jing takes a stratagem from Yue Fei's book, to fight the enemy whilst not fighting, not fighting whilst fighting, and a smiling Genghis asks him to explain. Guo Jing explains, and Genghis lays out a map presenting exactly the plan that Guo Jing had described. Guo Jing was amazed that, while he (and presumably Yue Fei) had the learning of others to draw on, Genghis knew it all from natural talent.
