What's the best way to have fights scored fairly?

Announce the scores every 3 rounds and before the last

I hate this idea, as soon as fighter A realises he cant be caught on points he is on his bike a running for the remainder of the fight.
Fighter B realises that although it is a close fight the judges have him so far down that he can't win on points and knowing that he doesn't have the power to KO him you are stuck with a dull ending to a potentially cracking final few rounds.

Those are just a few of the potential scenarios you get with announcing the score cards mid fight
