He killed such a highly trained and experienced assasin..... He put so much mud over three hatta katta guys much older and also trained for long..... They could have clawed each other out and actually climbed over the elevated mud levels (or over each others shoulders - like in Govinda for matki) and gotten out of the pit...... He could shoot bulls eye on the first attempt and all three times..... He could sword fight with all those guys without any knowledge..... They showed earlier when he was catching leaves that he could not even handle the sword......
I believe that Chandragupta was capable and intelligent.... Which was honed and sharpened under the expert guidance and lots of serios training.....
