	Abstract = {We introduce nine attack refinement principles stating whether the extension stays the same if we add a single attack, and we show that the grounded extension satisfies five of them. We define also an extension called acyclic attack refinement by adding a loop con- dition, and we show that the grounded extension satisfies one of the acyclic attack refinement principles. Moreover, we define an extension called conditional attack refinement taking alternative at- tackers into account, and we give an example of a conditional attack refinement principle satisfied by the grounded extension.},
