The Slide Save: Your ball is heading SDTM so you grab the sides of the machine and physically slide it sideways, legs moving some distance across the floor (possibly as much as inches). The ball kept its original trajectory but you've successfully moved the playfield underneath the ball far enough to get a flipper on it. Success! You've kept the ball in play without a full tilt and keep on playing.
Is the slide save considered cheating or just another form of nudging/pinball skill?
Under what circumstances is it OK to perform a slide save? At a friends house? In competition?
