How did Paul "almost" lose to Feyd?

So i know i'm a little late to the show but wow what a great story! One thing does bother me however. -If Paul can see past, present and future in a constant, how does he not predict Feyd's every move and completely overpower him?

Edit: Thanks for all the replies, i see how in some type pf way would make a little sense if i had read the books. :)
