thank you Lucas and Stas, this works for me.
so it would be fair to say that p:P39 by-passes the semantics of wdt:P39 with ranking*. for my own understanding why is a wdt property called a direct property**?

why doesn't the following query produce http://www.wikidata.org/entity/Q17905 in the result set?
The query asks for wdt:P39 wd:Q1939555, however current preferred value for P39 there is Q29576752. When the item has preferred value, only this value shows up in wdt. If you want all values, use something like:
https://query.wikidata.org/#SELECT%20%3FMdB%20%3FMdBLabel%20WHERE%20%7B%0ASE...
Or change "preferred" status on Q17905:P39.
