The MCTS part of the algorithm per se doesn&#x27;t seem super-important AFAIK from my brief read of the paper, except insofar as it shows that the &#x27;neural&#x27; part of the algorithm was meshing well with a broadly consequentialist idiom, which is important.  Another way of looking it at is that the neural algorithm was able to well &#x27;steer&#x27; the MCTS part, and it&#x27;s the neural steering which is important.
