After 2.e5-d5 it's only a threatened draw, there may be a defense. From the beginning 1.d5-d8, f9-f8 2.e5-d5 white's king has five open squares on the d-line from which to attack the a-edge but black only has four pieces to defend that edge so white can draw. Of course I've been in this position as black without the game ending in a draw but only because white tried to win, what would you suggest as black's 2nd move?
