As for Zhuge during Chibi, Ying Zhong Tian did mentioned that Zhuge acted as "Foreign Minister" and he's good at talking (BS and Flattering lah, LOL), the Fire strategy was not by him nor Zhou Yu also, i believed it's Huang Gai idea.
Expedition to Hanzhong and Ba Shu, Liu Bei left Guan Yu and Zhuge at Jing Zou, only brought Fa Zhen and Pang Tong along,
Interpretations, Interpretations .... Yi Zhong Tian is an academic so his reading between the lines & deductions are authoritative but at the end of the day, it's one man's point of view suitably backed by his copious research.
Talking cock is an art. 装神弄鬼 by KongMing in Wu in his duels with ZhouYu is also a form of psychological warfare & mindgames. It's true 黄盖 in the novel was the one who first propose using fire. But then not everything must Kong Ming 出面 right? The fire idea was obvious to those in the Cao Camp as well, but Cao pondered & dismissed it due to the direction of the winds. But his meteorological knowledge not as in depth, he is unaware of the decisive change of winds at the critical time of D-Day.
As for Pang Tong - really brought back memories. I read ROTK in novel & picture book form in the 70s as a school boy. When I read that Liu Bei now had the service of both 龙凤 (KongMing & PangTong), I thought, hor seh leow ! Got top combat heroes & now top strategists of the land !
So, for Liu Bei to leave KongMing behind & bring Pang Tong, I thought ok what ! Both also same level of reputation....
In adult years, upon hearing YiZhongTian's analysis, ok fair enough, very plausible Liu Bei by & by has hubris & not totally levelling with KongMing - trust not 100% is very possible. Probably, he knows if h is not around, martial-minded Guan Yu may benefit from KongMing's presence more, who knows? credible also right ?
Anyway, novelist demonises their villians & eulogized their heroes.
Later from a real-politik point of view, I began to appreciate CaoCao's political acumen. Personal views against his inhumanity like the way subok described - fair enough, inhuman etc. But for warlords, that sort of thinking is more or less the rule then exception. But in ROTK, bearing in mind confucianist ethos of the novelist where Liu-Han is the 正统, the subtle biases are inevitable.
Remember, Cao was depicted like a paranoid mad man suffering from migraine & killing HuaTuo in distrust. Also, he is amoral with women, whether competing for woman with his children or something like that, exact details sorry I lost touch oredy....
Anyway, whatever the difference of opinion amongst bros here, let's give each other some space, remain civil & let's all enjoy the Magic of the Chinese Classics !
