Hi Martin, thx for sharing the interesting results.
Can you also provide - for each simulation level - the complete distribution of results? So, how often Black wins by 1, 2, 3, ... White wins by 1, 2, 3, ... One would expect, that increasing the number of sims should give stronger concentration around 0, but MCTS is a strange animal...
