TASK DEFINITION: Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.
PROBLEM: Question: If there are an odd number of competitors at any stage of a single-elimination tournament, one player is excused from play and continues on as if he had defeated his (nonexistent) opponent. This is called "getting a by". Or "getting a bye". Who knows, maybe it's even "getting a buy", although I doubt it. My dictionary lists by as meaning "pass" in card-games, so that suggests that spelling. On the other hand, the image of the referee looking from the single player, to the empty and undefended far side of the field, and then back to the player, shrugging, and saying "Bye", is too strong to easily discard. Like other parts of the anatomy, everyone's got an opinion. I'm looking for a cite. 
Answer: According to the OED, bye is correct word. b. The position of an individual, who, in consequence of the numbers being odd, is left without a competitor after the rest have been drawn in pairs. (OED also points out a few other uses of bye in sports, but with different meanings.) And while it specifically doesn't clarify whether the competitor advances, the American Heritage Dictionary does point that out. The position of one who draws no opponent for a round in a tournament and so advances to the next round.

SOLUTION: no

I'd like to find nice abbreviations or alternative words for each of them that are not ambiguous and has reasonably large 'psychological distance' between. i.e. they don't look too similar i.e 'Auth' is not OK because it is ambiguous. At the moment I have just removed some letters Authtictn Authristn Any suggestions? 
Answer: What about this: Auth'ze Auth'tion? We were tought to put aphostrophoes somewhere to shorten a word.

SOLUTION:
no
