the gold chocobo as long as you know how and are rich is easy, you just need the right nut and i high enough racing rank. HP plus materia is a good thing to use and ultimate weapons are important but not vital(first time won without KoTR and clouds ultimate.) 2x and 4x cut are great and final attack materia combined with pheonix garantees a win unless you suck. if you have omnislah you will be able to kill him in one shot or almost. with good things like these despite how hard he hits you you cant lose.
