So, in order to use the Hide skill, you have to have either cover or concealment from your target. Let's say you're around a corner from your target, which gives you cover, so you can Hide. Now, when your target walks around the corner, they're in a straight line with you, and you no longer have cover against them. So you can't hide anymore and they automatically see you - no need for a Spot check.
Is my understanding of the rule incorrect? If not, I can't see Hide being useful very often.
I think you're correct, but it isn't that bad.
[As a side note, note that in that case I would also rule that if you're staying entirely behind the corner (and hence cannot see around it) you basically have full cover and don't even need to roll a Hide check, or alternatively you could peep around a corner (cover, but not full) but have to roll Hide to stay unseen.]
One possibility is that you might choose to make an ambush, so that as soon as the target goes around the corner you MAY have the privilege of a surprise round (while the target doesn't) if the target fails his Spot check.
The other possibility is that you probably have time to move away (or find another hiding spot) if you hear/see the target approaching.
These are two examples of possible ruling (I might not always rule exactly like this anyway...):
Case A: Completely behind the corner
- total cover
- no need to roll Hide so far
- you cannot see the target
- when the target is approaching the corner, you get a Listen check
- when the target passes the corner, roll Hide vs Spot
if Listen succeeds, you get to play in the surprise round
if Spot beats Hide, the target gets to play in the surprise round
which give 4 possible outcomes:
Listen succeeds and Hide beats Spot -> you ambush the target (only you play in the surprise round)
Listen succeeds but Spot beats Hide -> the target notices you at the last moment (both play in the surprise round)
Listen fails and Hide beats Spot -> he is surprised but lose timing (no one plays in the surprise round)
Listen fails and Spot beats Hide -> you are actually more suprised than him (only he plays in the surprise round)
The above is not much of an ambush tactic unless you are very good at hearing: better to be able to see if you want to successfully ambush someone.
Case B: Peeping from behind the corner
- partial cover
- roll Hide vs Spot already at this stage, because there is a chance you're seen
- you can see the target (no need for Listen checks)
- if the target doesn't see you with the first Spot check and walks round the corner, I would either automatically grant you the ambush benefit (a surprise round only for you) or maybe I could allow the target a second Spot check
NOTE: those Spot checks after going around the corner are only for the purpose of determining the surprise round. If you are not going to try an ambush, the target would simply automatically Spot you after a few seconds.
