Using Telekinesis for skills

[hollybargle]

Back again, still a bit confused on one aspect.

If I am using TK Grab from psionic powers, would I roll against my TK Grab skill if I was using it to grapple someone?

From Psionic Powers, p.54

Roll against skill to use TK Grab, whenever picking something up, moving it, using it, etc. If you know an appropriate skill (e.g., Judo for grabbing someone, Brawling for “punching” someone, Flail for wielding a chain), you may substitute an IQ-based roll for that skill, if better.

This sounds like, to me, if I was attempting to grapple someone, and my TK skill was better than my IQ-based wrestling skill, then I would use TK Grab.

Would this also be true if I was throwing an object (eg. TK Grab vs. IQ Throwing)?

Or grabbing a gun with TK and shooting it? (TK Grab vs. IQ Gun)

I mean, I suppose this makes sense in a way. I'm not actually manipulating a body with arms and limbs, I'm using psionic force to achieve that. I'm not actually lining up the gun with my hand, I'm using my mind to achieve the correct aim.

It just seems like this might be open for exploitation. I would really only have to up skills in one thing, if I wanted to improve my offensive capabilities.
