Gamova is very serious about making it to OG roster (source).
Will be an interesting fight between Goncharova, Gamova and Malykh for 2 spots unless Marichev finds a way to take them all, but IMO that would be destined to fail because neither of them could play as OH on a good level. Goncharova currently is the best, Gamova by far is the most experienced and still can play on a high level, Malykh is the youngest and also performing on a high level. You never know what goes on in Marichev's head, but if he insists so much on having Sokolova in the team, I think he will take Gamova for sure as well.
