Turtle-ing in Chess

As the father of a teenage son I do learn new expressions from the gaming world, usually hearing them shouted at the TV after a particularly disastrous outcome. One expression that is both common, and reasonably self explanatory is 'turtleing'. This involves setting up a defensive structure or system and inviting your opponent to come at you. Done right it can result in a kind of victory, especially if annoying your opponent is an acceptable outcome.
Fortunately for chess, such a strategy is usually doomed to failure. Some players have attempted to build a career out of such a strategy (Karl Galli being a local example), but in the long run it doesn't offer much. The Hedgehog is probably the closest mainstream opening system that embodies this strategy, but you have to have a special kind of patience to make this really work.
But such a strategy is enticing to new comers, especially those who have been hacked to bits more times than they are comfortable with. Often moves like a6, e6,d6, b6 and g6 get played, and the rest of the pieces huddle along the third rank, trying to avoid trouble. Nonetheless sometimes this does result in a positive outcome, especially if the opponent overreaches.
A famous example of this was the following win by Tony Miles over Anatoly Karpov in 1980. To be fair to both players Miles had no intention of cowering in his half of the board, although White did start of with more space. But a couple of well timed breaks by Black gave him better board control, and technique did the rest.
