an oob is like the sideline in football...once u cross it, the shot is dead. there could be a walled up house shot that has an oob, as the wall could end at the 3rd board or so and have solid oil up the outside 3 boards of the lane. as long as u keep it inside of there, its like bowling on a 34 board house shot. a reverse block is exactly what it says...the oil is in the opposite position that you are used to on the lane. any time there is more oil on the outer 2/3 of the lane(typically the outer 10 boards on each side), than on the inner section(2nd arrow to second arrow), its a reverse block. theres no easy part of the lane to play...going from really deep and tring to keep it around the 12th or 13th board is what i usually try to play...but noone really gets a chance to practice at them. hope this helps
