Added a subvariation, and fixed a typo.

Added another variation, and improved some wording.

The goal would be to force the other's king not to move, while having one's own king free to lose tempi (e.g. Kh7). Of course white should win at this game, but maybe both kings only must not commit themselves into the f5 g4 h5 formation. | |

In the first diagram, 7...Kg5 is necessary in order to stop the white pawns continuing to advance - otherwise essentially the same thing that happens after 17...Kf6 would happen immediately. 9...c6 doesn't seem to help - see the variation I've added to the diagram. | |

Added a couple of variations to the first diagram.

| Nov 17, 2014 at 6:09 | comment | added | Nikana Reklawyks | So you're saying the initial position is already a black-losing zugzwang, given proper play ? In the first diagram, 7... Kg5 looks like a blunder, what if B just pushes pawns ? Is 9... c5 and c6 the same ? | |
