“just play better poker” like that’s an easy thing to do in a game of chance and incomplete information, with variance having years or decades long tails. not to mention it’s an unsolved game, so “better” poker doesn’t even really have a set definition and depends on tons of variables. and they literally knew what hole cards were coming - that’s vastly more of an edge than playing “better poker” than someone.
