Neftekhimik performed very respectably away against Avangard Omsk, took a lot of shots on goal, and scored 6 goals in 2 matches. It seems to me that the match will not be easy for Avangard Omsk, and Niznekamsk should score 2–3 goals per game.
Volga are desperately fighting for survival and have been consistently scoring in matches this year; S. Kostroma have also scored in all 4 matches.
At the same time, they are near the top of the league table.
