These are 3 separate concepts that deal with the Dimensional Zone Theory.
Kirk, in your "Boot to the groin" example, you "Disturbed" his height zone, which may or may not have "Cancelled" his height dimension. If it cancelled the height zone, then it could be considered a check. Remember a check is intended to only "momentarily negate the action of another." I would think that in all liklihood you had this momentary check.
Having said that, I really don't think it was a check. Confused yet? I think you used a strike, front snapping ball kick, to the intended target, the groin, with the intent to injure or create a desired reaction for you next retalitory strike (borrowed force, or positional advantage.) You inadvertantly, or purposfully created a check by your strike, but was that your intent? No, you were trying to kick him between the legs. You could have done a front thrusting ball kick to the inside of the groin, checking depth and width, and cancelling height probably. The groin strike itself should check, to some extent height and depth, but not width, (as he falls grabbing your legs.
A lot of Kenpoist think that a check is more of a "control" that lasts more than "momentarily." I think that if it lasts more than a fraction of a second, you are moving into a Contact Manipulation but employing Restraining Pressure, for the intent of striking or manuvearing, not contact immobilization.
Well, you get the idea, Kenpo is a sophisticated world of limitless opportunities for retaliatory strikes.
