I don't think so. Everyone seems to agree that MCTS only gets stronger in the endgame, and that AlphaGo started making weird moves towards the end because it thought it was already losing, which by definition means there's no strategy leading to a winning position.

...However if it's true that it couldn't find a way out, shouldn't its probability of winning have hit ~0% much earlier? There was still a long time between when it started acting strangely and when it resigned.
