Moving c1 to king
Tiny (3 or less) king endings

Our task is maneuver the game to the previous diagram's Critical Position 1.a5-d8 e7-d6

[ 1...e7-f8 2.d4-e5 f8-h6 3.e5-h2 h6-f8 ( 3...h6-g7 4.c3-b4 a3:c5 5.h2-d6 c5:e7 6.d8:h8 ) 4.c3-b4 a3:c5 5.d8-e7 f8:d6 6.h2:c7 c5-d4 7.c7-a5 d4-e3 8.a5-e1 ]
2.d4-a7! d6-f8!
[ 2...d6-b8 3.d8-b6 b8-d6 4.a7-b8 d6-e7 5.b8-e5 e7-d8

6.b6-a5 d8-e7 ( 6...d8-g5 7.e5-f4 g5:b4 8.a5:c3 ) 7.a5-d8 e7-f8 8.d8-g5 Critical Position ]
[ 2...d6-h2 3.d8-b6 h2-b8 4.b6-f2 b8-d6 5.a7-b8 d6-e7 ( 5...d6-f8 6.b8-e5 f8-h6 7.f2-b6 h6-g5 8.b6-d8 g5-h6 9.e5-b8 h6-c1 10.d8-a5 ) 6.b8-e5 e7-d8 ( 6...e7-f8 7.f2-h4 f8-h6 8.h4-d8 h6-c1 9.e5-b8 c1-h6 10.b8-h2 h6-c1 11.d8-a5 c1-e3 12.h2-g1 ) 7.f2-h4 ]
3.d8-c7 we need to force black king to take c1-h6 line - but how? f8-e7 4.c7-e5 e7-d8! We need to take d8 back and we can do it only from b6 5.a7-f2! an important waiting move d8-e7
[ 5...d8-g5 6.f2-b6 g5-d8 7.b6-a5 d8-e7 ( 7...d8-h4 8.e5-g3 h4:b4 9.a5:c3 ) 8.a5-d8 e7-f8 9.d8-g5 ]
6.f2-h4 e7-f8 7.h4-g5 we came to a previous diagram 2-0
