Try this one? PUCT used in AlphaGO http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.172.9450&rep=rep1&type=pdf

Maybe PUCT is used in AlphaGo since

  1. The available actions are TOO many choices (branch factor ~250)
  2. PUCT needs episode context, which in AlphaGo's implementation, is the probability distribution generated by the policy network

In Hearthstone, the possible actions are not so many, and we do not have a policy network handy.
