In the bogo indian defense retreat variation discovered attack, Black uses a retreating move (often …Nbd7 or …Ne7) to reposition a piece so that another line opens—creating a discovered attack on a target. The defining feature is that the “retreat” is not just safety: it clears a path (commonly along a diagonal or file) for a more forceful follow-up.
