Another day Peter Kapler placed a position and asked if black can win the
endgame.
Alexander Kure place some analysis showing that black is winning and I agree
with the analysis. Today I was testing Rebel Century with the position and
I found a mistake. The bad move is 8. Kb4, better is 8. Kd4, because whites
draw:
8/1p6/5k1n/8/4P3/5P2/3K4/8 b - - 0 1
1... Ke5 2. Ke3 b5 3. f4+ Kd6 4. Kd4 Nf7 5. e5+ Kc6 6. f5 Nd8
7. Kc3 Nb7 8. Kb4? (8. Kd4! Nd8 9. Kc3 Kc5 10. e6 b4+ 11. Kb2 Kd6 (11... Kc4 12.
e7 {+-}) 12. Kb3 Nc6 13. Kc4 Ke7 14. Kb3 {=})
However, I think the analysis below shows that blacks wins, and shows that
the Alexander's idea is rigth:" The idea is to blockade White's pawns and then
force Black's b pawn. As White will be in Zugzwang, he has to give way to
black's
b pawn."
I found the possible winning line with Rebel Century and I checked it with
the help of Hiarcs7.32.
