well, itachi, in the end, lost to sasuke mainly cuz of lack of chakra (that may have been from his sickness, or not, so dint ask me why), among other things. if he had a bigger chakra pool, he could've lasted a bit longer, I guess. can chakra give u energy as well? (in the sense of: if two people are very tired, is the one with more chakra gonna last longer aka stay awake longer?)
