Strategy Transformation Proof
Patrick Traill I think this is a handy concept, but if anybody knows a different term, perhaps this could be made an alias (after merging any content not covered there).
A strategy transformation proof is a proof of a statement of the form if one can achieve result ``R`` in position ``P`` then one can achieve result ``S`` in position ``Q`` by showing that if there is a strategy to achieve ``R`` from ``P``, this can be adapted to a strategy to achieve ``S`` from ``Q``.
An particular case is a proof of a statement of the form it is optimal to play ``M`` in position ``P`` by showing that any strategy for winning from ``P`` can be adapted for use after playing ``M``.
