Zombie Openings are opening lines from the past which died out, and then were reanimated by a modern player.
Some examples include Vladimir Kramnik revitalizing the Berlin Defense and the Catalan Opening from the dusty annals of History.
In this thread we can analyze modern Zombie Openings, and also try and create our own by looking back over "outdated" lines and finding novelties which make them playable again.
All analyisis welcome!
