Rivalries in the KHL come in many categories. As the league is still young, many of the rivalries have carried over from the days of the Russian Superleague, while others are new and may disappear. Some are based on geography, while others are based on team names or organization that these teams belonged to back in the Soviet Union. Not all teams have pronounced rivalries that don't change with each season - this article attempts to chronicle only those that last for multiple years. In the European tradition, rivalries in Russia are referred to as "Derbies". Geographic rivalries Capital City Derbies HC CSKA Moscow vs. HC Spartak Moscow HC Spartak Moscow vs. HC Dynamo Moscow HC Dynamo Moscow vs. HC CSKA Moscow Every year, sports news outlets even calculate who the Moscow Champion is, based on games just between these three teams. As of the second season of the KHL (2009–10), all the Moscow teams are in one Conference, making rivalry matches more common. Due to hockey being less popular than association football and other sports in Moscow, teams based there usually suffer in attendance. Capital city derbies, however, are always attended far better than other games. Moscow Oblast Derbies Atlant Moscow Oblast vs. Vityaz Chekhov (Defunct) Atlant Moscow Oblast vs. HC MVD (Defunct) Khimik Voskresensk vs. HC MVD (Defunct) Vityaz Chekhov vs. HC MVD (Defunct) Vityaz Chekhov vs. Khimik Voskresensk (Defunct) Two Capitals Derbies A continuation of the general rivalry between Saint Petersburg and Moscow, this rivalry encompasses SKA against any of the Moscow teams, although not the teams in the Moscow Oblast. The most tense rivalry is between SKA and CSKA, which called The Army Derby. SKA Saint Petersburg vs. HC Spartak Moscow SKA Saint Petersburg vs. HC Dynamo Moscow SKA Saint Petersburg vs. HC CSKA Moscow Tatarstan Derby Ak Bars Kazan vs. Neftekhimik Nizhnekamsk Not as seriously regarded by Ak Bars as by Neftekhimik, this rivalry nonetheless is significant in that Ak Bars has been known to poach players and coaches (Vladimir Krikunov was poached just before the 2011–12 KHL season following Zinetula Bilyaletdinov's hiring by the Russia men's national ice hockey team). Ak Bars Kazan is regarded as the 'older brother' of Tatarstan hockey, and the rivalry reflect a sibling mentality.
