Movie name about Russian prison

Hi,
My mom saw this movie when she was younger. She isn’t sure if all the details are correct or if she’s switching up multiple movies. But the story is that 2 American hunters somehow got to Russia and where captured and had to go to prison. In the prison they have to play chess to rank up. Eventually one of the hunters have to play against the best player. She also said that Russian roulette was somehow involved.
I can’t find it anywhere.
Thanks
