The playing strength of an MCTS program is dominated by the correctness of the simulations, especially of L&D. Prior knowledge helps a little. David pointed out after the first Densei-sen (almost three years ago): >All mcts programs have trouble with the positions near the end. The group >in the center has miai for two eyes.

Without improving the correctness of the simulations, MCTS programs can't go up to next stage.
