Easier wins
Become skilled with the jab and straight combo. The CPU will parry it after a few times. Then, throw your hook or uppercut.
This will work in any fight. Constantly Haymaker your opponent. When he is in knockdown mode, Haymaker them one more time to knock them down. Sometimes you can hit them even more when there on their way down. In hard mode do not try to Haymaker frequently, as you will miss a lot and your opponent can hit you harder.
Go to the settings and turn off illegal blows. When fighting, use an illegal blow. It is a lot more effective than a normal punch.
Better ring performance
Pimp out your ring entrances. The more extravagant they are, the more the crowd will like you and the better you will perform.
Avoiding knockouts
In order to avoid a knockout, when your opponent gets close to you perform a grab. You will then exit knockout mode.
