Puzzle of the week #4

Chess Diagram: 


Chess is a game full of resources; one just needs to pay attention to all details, regadless how good or bad the position seems to be. In the above diagram White appears to be completely lost.
White to move and draw.
Surprisingly this was the end of a real game (and not a study) between A. Kramer - Rutgen, 1922. The answer will be published next week together with puzzle #5.

Puzzle #3 solution:
This endgame can be saved by holding the opposition:
1... Kb7!! 2.Kc5 Kc7 3.Kd5 Kd7 and holds the opposition (or the long opposition). Draw!
In reality Black did not put up a fight after:
1... Kc6?? 2.Kc4 Kd6 3.Kd4 ... wins the opposition and the game. Possible continuations:
a) 3... Kc6 4.Ke5 Kb5 5.Kf6 Kxa5 6.Kxf7 Kb4 7.h5! a5 8.h6 a4 9.h7 a3 10.h8Q ... right on time 1-0
b) 3... Ke6 4.Kc5 Ke5 5.Kb6 Kd6 6.Kxa6 Kc6 7.Ka7 Kc7 8.a6 ... and Black has to move something 1-0
