Endgames can be a silly dance on the knife's edge. Here is a snapshot from a recent training game (see below). Maybe Mr Fritz is in a joking mode or there are a lot of blunders to be made in the position.
Maybe Mr Purdy has some clever rule to help us survive similar endgames. I did not find the proper move but I did not get the proper(?) punishment for making the naturally looking loosing move (Kd5).
A great chess teacher Valeri Lilov pointed out the fact that this can be viewed as an example of Corresponding Square.There is a little more to be learned.
