I'm pretty sure I know the answer, but I want to make sure, so I don't mess it up.
Situation:
Light Horse is combat trained, so knows the attack trick.
Handle Animal says that ordering it to attack is DC 10 Handle Animals and a move action (it's just a horse, no Animal Companion).
Ride says that using the mount to attack is a free action and a DC 10 Ride check.
So I assume it's like this:
If you're not mounted you have to use handle animal. Ok this part is obvious, if you're not mounted you can't use ride.
If you're mounted, you make a DC 10 ride check, the horse moves to the enemy if necessary, makes it's attacks against the enemy, and you can do your own thing, attacking yourself or casting a spell etc.
NO handle animal check is necessary, it's covered with ride already.
Just moving the horse without attacking requires no check at all (except maybe a DC 5 for guiding with knees)
Or would I actually have to make both checks when mounted?
Either check should do it, otherwise a knight or mounted fighter would never be able to attack in the same round as his ride.
