His name is Sun Tzu. He wrote "The Art of War," and if you see his statement underneath, it's along these lines: "Attack him where he is unprepared, appear where you are not expected."
Er heißt Sunzi und schrieb "Die Kunst des Krieges". Seine Aussage hier unten bedeutet soviel wie: "Greife an, wo er unvorbereitet ist, erscheine, wo du nicht erwartest wird."
