Yes but the position is position number 25 in the test.

You can prevent the confusion if you number your positions 1,2,3
but I see
arasan.4
arasan.6
arasan.11 so epd2wb gave me the following output that suggest that movei
completely failed in understanding the position(it did not see that h4 is
losing)

Nr:   25
Id:  arasan.81
Fen: 1B4k1/5p2/K5p1/7p/P4P2/5P2/8/6n1 b - - 0 1
Bm:  f5
