Just for fun a position which is a simplification of a famous problem from Henri Cordier.
White to play and win
For a human the win is quite easy : white plays the 15 moves
50-44-49-43-48-42-47-41-36-47-42-48-43-49-44-50
while black plays only its king between 45 and 50. After that, black is forced to move a man, and white plays again and again its sequence in order to force all the black men to move.
After 15x17 = 255 moves we reach the following position
Black to play
in which black is force to play its last move 46-41 37x46 B+
Isn't it a good example of the difficulty for computers to analyse like a human ?
