At least on the C=64 version, what I would do is to time the bounce of the pole just right. It was many years ago that I played it, but I was pretty good and hardly ever lost. I probably can't explain it any better that that because you'll probably figure it out with practice anyway. You have to hit the shield, if that helps any.
Hmmm.. how about this. Try aiming high and when the dude comes close enough, hit the button while the pole it dropping. That's the best I can get my brain to think.
