The heavy piece middlegame -> ending

 Most people regard chess as a game of three phases. Opening, middlegame and endgame. This is taught in instructional books, and is often used in chess programming. However, the transition between the phases isn't always clear. In the following game, it contains elements of both the middlegame (significant material on the board, not safe to bring the king out) and the ending (pawn promotion is the goal). John Nunn might consider this a 'tactical ending', while Mihail Marin refers to it as the 'Fourth Phase'. It turned out that the win depended on both features being present, with the lack of king safety allowing tactics that assisted pawn promotion.
