> Someone with perfect strategy would have an answer for any deviation. Someone verified there is a perfect strategy, using tons of computational resources and lots of time. The game tree they explored may have millions of billions of nodes, of which only the top layers could be saved. To use a perfect strategy in an actual game, you need to have it stored in some format that allows near-real time lookups. Such is the difference between weakly and strongly solving. EDIT: Strongly solving goes beyond the latter, requiring real-time best play from arbitrary positions.
