Amazing ride . Who has said the knight is a limited piece ?
By the way is this position in tablebases ? If yes, is this variation the "best" for black ?

This one seems easy, so i probably miss something.

I think white captures the d pawn, black the c pawn. But then white have to run to the h-file over the squares e6 and f6, instead of a straight line. That should be enough to keep the black king away.

I don't agree .

1.Kd6 Kc4 2.Kxd7 Kxc3 3.Ke6 Kd4 4.Kf6 Kd5 5.Kg7 Kf6 6.Kxh7 Kg7 draw

The answer seems extremely simple to me.. I dont know if I'm right -but here is my variation..

1.Ke5 Kc4
(1...Kc5 2.Kf6 Kd6 3.c4! +- )

2. Kf6 Kd5 (2...Kc3?? 3.Kg7 d5 4.Kh7 d4 5.Kg6 d3 6.h7 d2 7.h8(Q) + +-)

3.Kg7 Ke6 4.c4 d6 (otherwise white plays c5)
5.Kf8! (winning manuevre) Kf6 6.Ke8 Ke6 7.Kd8 Kf6 8.Kd7 Ke5 9.Ke7 d5

10.c5 d4 11.c6 d3 12.c7 d2 13.c8(Q) d1(Q)

14.Qh8+ Kf4(only move!) (Kd5-Qd8+ , Ke4-Qh7+)
15.Qh7 +- 1-0

(black's king is a hinderance for black as he can't give perpetual check ) for eg. 15...Qe2+ 16.Kf8 (idea -Qf7,h7, h8)

1-0

Is there maybe a plug that makes it possible to move pieces at the board??

Maybe someone can suggest such a thing!

Nice study of last week, mr. Afek!

The night walks in a wide cirkle from g1-h3-g5-f7-d6-b5-a3...to stop the b-pawn.
