This is not merely a theoretical possibility. When one player is "stuck" with a tile, then playing out all remaining tiles is impossible. In that situation the optimal strategy for both sides is usually to play one tile on each turn. Maven uses a different approach. The B* search algorithm is a selective-depth, progressive-widening algorithm that guarantees to find optimal solutions to two-player games when one can compute upper and lower bounds on
