   to put the issue very simple: *there is clear evidence for a co-regency at the end of akhenaten's reign. that is a fact *there is evidence for at least one ruler inbetween akhenaten and tutankhamun. that is a fact *there are several sets of royal names associated with the two points above. that is a fact *these names share similarities between them (and with names of other amarna royals) but also have differences. that is a fact *one set of names is emphatically feminine, the others are gender neutral. that is a fact *based on those facts some serious scholars maintain that there are two distinct individuals involved, one female and one male. that is a theory (or more precisely: a collection of theories that all subscribe to that basic premise) *based on those same facts some other serious scholars maintain that there is only one (female) individual involved. that is another theory  saying that is neither an editorial decision nor original research, it is simply stating the current state of affairs in this matter. reasons one and two given at WP:MERGE are good grounds to merge articles that deal with these theories (likewise reasons three and four are good grounds for merging this article as well) and WP:NAME provides good ground for naming such an article smenkhkare.
