Maybe again . . . Worry about the immediate problem first, and then worry
about the "what if's" later. Triceratops wouldn't have to gore it's
opponent, just keep those horns in its face.

I saw some film footage somewhere recently; An Elk using his antlers to hold
a Grizzly at bay on a gravel bar. The Elk was injured already when the
footage began, and while the Elk put up a good fight, and used it's antlers
to good effect, the Grizzly did prevail. Antlers are primarily used by
their male owners to clash with other males over the females during the
mating season, and for most of the year they have no antlers at all. My
point is: this particular Elk had the equipement, and used it to defend
himself in this situation. Most animals will use whatever they have when
push comes to shove. Whether it's a T-Rex too hungry to wait for something
to die, or a Triceratops with it's back to the cliff, it seems to me that
these animals, prey or predetor would use whatever resourses they had; teeth,
horns, speed, stealth and/or brains.
