Ive had similar problems to u with the stamina and i have come to the conclusion there's nothing u can do about how gd the computers stamina is wether their an average fighter or ray robinson u just have to do ur best with the stamina u have and as for the cuts i had about a 8 fight run in which i got cut everytime within the first 2 rounds but after a while it just seemed to stop as his chin and cuts get higher rating nd also if u got a high cut early on it can be a big risk going all out cos if u fail to knock him out ur stamina will be low therefor ur life wont go up nd the damage of each punch increases due to the cut and from that point on u probs wont last the whole fight as i found out against ray leonard.
