offset, offset, offset.
a guy forcing the HO is generally an easy kill, not in a HO that is.
when they guy points his nose at you, accept it. do NO fly directly at HIM tho. offset maybe a half-gunsight to one side and start dropping your nose to go just under him.
If he continues to push for the HO shot. he will be correcting on your by diving and turning.
all this has been setting him up for a lead-turn reversal.
here is the 'tricky' part. just befor he opens fire. roll into him and pull hard Gs across his nose. this, at best, gives him a snap-shot.
Now, almost as soon as you have pulled the Gs, let off the Gs, roll up-right and pull into a vertical move.
Roll to put him in view and decide what to do based on his reactions.
if he extends, loop onto his six. if he flat turns, stay high and watch for an opening.
and worst case, roll away and extend to get out of a bad spot.
