The entire chapter was an infodump. And again, if the "struggle" between Harry and Dumbledore/Voldemort was likened to a chess game, Dumbledore would start as a black king with all his pieces missing and himself in check while Harry would start with eight queens. Do you think that makes for an interesting match?
