That's not strictly true. With enough samples, or fast enough playing bots, you can explore that domain automatically. There are many different approaches from expert systems which are purely human heuristics to minmax which can be defined purely in terms of in-game points difference.

Why the situation is advantageous may be just "because enough Monte Carlo simulations starting with it end up winning".
