In my professional opinion, it is preferable to bet on the victory of "Mammoths Yugra" in the match against "Chaika." After all, "Mammoths Yugra" demonstrated a high level of play by defeating the strong team "Kuznetsk Bears," and they have a reliable defense. Additionally, the hosts are leaders in home wins. While "Chaika" had more challenging matches with "Irbis." Taking these factors into account, betting on the victory of "Mammoths Yugra" looks reasonable and promising in this situation.
