It would be easier to show but I'll do my best to explain. It only works if you're snagged only by the hooksin a log or something. If your line is wrapped around something, the B and A will probably just mke it worse. All you do is put tension on the line (a slight bow in your rod), then pull the line ith your off hand. At this point, it looks like you have a bow and arrow pulled back and ready to fire. Release the tension on the line (let go of the line and point your rod at the snag). The point is to try and get the lure to pop back out the opposite way from when it got snagged. Saves a lot of time instead of going around behind the lure and tugging. It works best with a floating lure and line with a little bit of stretch to it, IMO. This allows the lure to float up and away from the snag if it gets freed and the stretch in the line gives a better snap. Hope that helps.
