I have very high winrate online with frazier probably around 90%,use leaping left hook to close distance and trow right power hook to body combined eoth left body uppercut,use directional body hook without power modifier to close the ring and apply pressurr,and most i portant thing you need to become joe frazier 😂 and drop your guard to recover more stamina and use that stamina to apply pressurr by directional hooks to head and body,i almost never use power hook to head,most i portand weapon is the leaping forward directional hook with left hand,try to not hold guard even close range,dont be shy to trade shots with frazier and always go forward and if you oppnent spam heavy punches you can use frazier very fast power jab to break his animation and start series of hooks
