Bah, never mind, I was wrong. I was predicting for Spain. Turns out that these code works out for Netherlands, too. My prediction:
SPAIN:
NC: New Champion (Spain haven't won a world cup)
1253: Coordination for Spain country.
HZ6: Key player for Spain xavi HernandeZ (HZ) and 6 is his number at BarcelonaFC.
.. And from my friend which chooses for Netherlands:
NETHERLANDS:
NC- Nassau Colonies
1253- The year when the Holland are in their greatest.
HZ6- Holocaust Zuiderzee building.
So yea, my prediction failed
@Bojan: yep, too bad he died, didn't he?
