I use the duck and step move a lot and it seems to give me lots of Kayos. Its just like a fireball from street fighter (any fighting game dorks out there??)

Consider what you choose as your characters power shot, too. I like to duck and throw a solid left hook... You can't adjust the type of shot to be your money shot after you make the character, so remember before you hit "Begin Career" :P

I rarely go to the cards, bc if someone is a pansy the whole fight I'll throw myself at them till one of us gets Kayoed in the last 2 rounds!
