grappling & posture and grappling & letting go

[zedlopez]

1. I had thought that when the Basic Set said you could try to pin someone if you were grappling their torso and they were "on the ground" it meant they could be any of lying, sitting, or crawling. But now I see that DFRPG says specifically that they must be lying and I'm wondering if I had the Basic Set's intention wrong all along. Can you attempt to pin someone who's sitting or crawling?

2. B370 says that when you're grappling someone "Letting go is a free action on your turn", emphasis in original. Martial Arts p. 122 says "The grappler has no penalties. However, he can't parry with a limb without releasing its hold on his victim. To retreat or use Acrobatic Dodge, he must let go with all of his limbs." So... is it meant to be possible for a grappler to release their hold to attempt an active defense that would be impossible otherwise? The point of the former seemed to be to say no.

3. When the takedown rules say the grappled opponent must be standing, is that meant to be read as 'on their feet' and thus includes crouching? Or does dropping into a crouch really make you takedown-proof?

I always figured crouching was still a form of standing. In basic set there's always "sweeping kick" to take down non-standing opponents. "Force Posture Change" in Technical Grappling fixes it.

I've never paid attention to any of that nonsense when running games. You can pin someone who is standing against a vertical surface, or against another surface if sitting/kneeling, etc; letting someone go can always be done at any point during a turn*; you can perform a takedown to someone kneeling or sitting, etc.



* A Turn lasts until you end it to take another one, so... it's always someone's turn even if it's only the defense portion of the their Turn.

3.4.1.3 In combat, when does your turn end?

Thus, one could say your turn doesn't end until your next one begins. But everything that refers to turns in the Basic Set – with the sole exception of the active defense rules – hews to the more restricted usage above.

There's a much longer discussion about it somewhere on the forums (but I'm not finding it), but essentially it boils down to "Look at the third sentence in the quote you used above, extrapolate as needed".

I posed these to Dr. Kromm by Private Message; he replied thus:

To pin someone, they have to be "on the ground," which is used throughout the rules to mean "lying face up or face down." Crawling and sitting are not lying down, and thus don't count as "on the ground" and don't permit pin attempts.

Thanks, Dr. Kromm.
