Question about MCTS

[MorelT98]

First, great implementation, this really helped me understand how AlphaGo Zero works, and I’ve used it for other games as well.
There’s is still one thing I couldn’t understand though. Why do you return -v instead of v when you do the Monte Carlo tree search?

I think that's because it is v to the current player but it's -v to the opposite.
