Yet the most interesting part is when two players from the same team make turns after each other, what kinda reminds index-2 nim but without taking 1 stone from one heap. Probably with correct AABB — ordering it won't be hard to come up to a good BAAB one, since there should be some invariant. Any ideas/hints?

Just analyze winning/losing states, not that hard.

    Ok, thanks. Actually, it can be found in the internet. But just bruteforcing isn't interesting, I was rather interested in theoretical solution. But anyway, thanks.

Can I get some hints? I have already solved when players of both team alternate but am unable to find out how to solve other cases
