I am learning Dutch right now, and am still unclear on compound nounds: is there a limit to the length of words for a compound noun, and is it incorrect to leave what can be a compound noun, two (or more) separate nouns? For example I play chess and if I were in a (chess) bookstore in Netherlands chess cities Alkmaar or Wijk aan Zee, and I want to ask about if there are "Najdorf Sicilian Old Main Line 6. Bg5 Variation chess opening books", all of which are nouns related to chess, can I leave some nouns out of one long compound noun, or does it have to be "NajdorfSicilianischeOudeBeljangrijksteLijnen6.Lg5Variatie'sschakenopeningsboeken", or can I say/write "Najdorf Sicilianische Oude Belangrijkste Lijn 6. Lg5 Variaties schakenopeningsboeken"? Sometimes I have problems knowing when to form compound nouns.
