I assume this is the game in question, with the difference of venue being a typical error.

I believe Averbach is the correct spelling referenced here - http://nl.wikipedia.org/wiki/Joeri_Averbach

Um?? same guy is here

http://en.wikipedia.org/wiki/Yuri_Averbakh

Except his name is Yuri Averbakh and also in chess-base the name is spelt 'Yuri Averbakh'. Weird isn't it?

Just alternate spellings. Sometimes when names are referenced in different languages the spellings can slightly change.

Eric Schiller thought Harry Kasparov was a better rendition than Garry.

Garry is the version that has won the day though, I think.

Especially slavic names.

"Averbakh" is the correct english transliteration of the cyrrilic "Авербах", "Averbach" is the correct transliteration into dutch (perhaps among others) of that name. The idea is to spell the name in the new language in such a way that native speakers of that language would pronounce it correctly. No englishman would ever pronounce "Averbach" correctly, unless he already knew the name. Of course it's just a minor mistake and one that is made often, although usually the transliteration into a dominant language (i.e. english) prevails. "Alekhine", for instance, is frequently spelt as both "Aljechin" and "Alekhine" in dutch.

Rather cheecky, by the way, of Patzer24 to offer the link to the dutch wikipedia entry, without comment.
