I was watching Daniel Naroditsky's speedrun on YouTube and in his 1870 video (https://youtu.be/3UqPa5eV2e0?t=987) his opponent (rated 1889, playing black) played a very bizarre opening by pushing almost all his pawns before developing any of his pieces. It appears to be someone trolling, but they seemed (to me) to play a really good middlegame/endgame. Is this considered a serious opening, or does it seem like more of a joke opening? Or was it a trap that throws lots of players off?
