As we all know, Chekov joined the crew in S2 thus creating an inconsistency when Khan recognizes him in the movie. The common explanation is that Chekov was below decks at the time and Khan saw him then. This explanation is supported by Chekov's apparent knowledge of Kirk's prior use of the corbomite bluff in The Deadly Year. BUT he does not know who Harry Mudd is in I, Mudd. Mudd's Women comes in between those two episodes so shouldn't he know of both corbomite and Mudd??? How can this be resolved?
