The Remote Knight Promotion-In A Kindergarden Problem


I was fiddiling around with Knight promotions today when I hit upon a funky idea-a knight promotion to avoid stalemate. All I had to do was somehow discourage a rook promotion! Then I realized something partway through my work-I was doing the remotest of remote knight promotions! Krabbe’s #89 has a few examples.

Intially, it wasn’t a kindergarden problem, but it almost was. After perhaps an hour of work, I produced the following.

WTM, #7

(= 7+7 )


A knight promotion not for a waiting move nor a blocking move (see Lloyd’s #3 in Krabbe), but to avoid stalemate! A rook promotion works too, but then it is an #8. And all in a kindergarten problem no less!

What are your thoughs? Any anticipations?

Finally found a version with one less piece!

WTM, #7

(= 6+7 )

In Die Schwalbe, Okt-Dez 1967, there is an article by Otto Nerong "Die entfernteste Springerumwandlung". For this particular idea he gives P1273184.
