I have "always" been somewhat intuitively rooting for countries neighbouring witch CZE (Slovakia, Austria, Germany, Poland, although Poland hasn't been exactly great in hockey), perhaps because I know the cities, culture, languages, some people there. The same goes for Slovenia because I've been liking it there, it is a lovely country, and for Norway and Latvia (the same reason). With Sweden and Finland, I like the countries too but I assume they are strong enough and have enough own supporters, so to say.
Always have been respecting Canada as the "cradle of hockey" and the country where hockey is simply the biggest of all countries in the world. Never have been rooting for Russia which is related to the historical rivarly between Czechia/Czechoslovakia and Russia/Soviet Union, still I respect the great tradition of the Soviet/Russian hockey school.
