Marcelo, Demian, and Philzinho help Jon investigate strategies and tactics against an opponent who happens to skillfully 'Ride the Line', so to speak: Staying conscious of where the boundaries of your match reside is an advanced part of developing the skills necessary to beat opponents at the highest levels; this is particularly evident when you are attempting to consolidate an offensive maneuver near the out-of-bounds. What works is largely contextual, e.g. in MMA, oftentimes there will be caged wall to deflect anyone from taking advantage of resets. Many older organizations would even allow a submission-hold to be broken after a combatant grabbed onto bounding ropes of the ring; this is still evident in much of professional wrestling. Some competitions resorted to contesting inside a sloped pit to encourage fighters to more easily find the center. Phil facetiously suggests using a circle of American Gladiator-style padded shields to bump grapplers back into fair play. In terms of most grappling events however, you must remain cognizant of how your opponent may try to game certain techniques when close to the line.
