If you learn this pattern it's a piece of cake. But for starters, throw a rights to his head when his eyes turn yellow. You may have to adjust the timing just a bit depending on if you are just slightly early of slightly late on that que. Also, he will usually duck and throw a punch if you throw a left to his head. So you can throw the left and hold to dodge as your punch is out. You should dodge and be able to punish him after that. Repeat!
