something is fishy here, I believe your given positions is not correct. Quarks
perft:

perft 10
 1:               8      0.000s
 2:              33      0.000s
 3:             270      0.000s
 4:            1664      0.000s
 5:           13931      0.000s
 6:           94162      0.015s
 7:          793785      0.094s
 8:         5681152      0.750s
 9:        47559506      6.468s
10:       359458182     49.047s

I count definitely 8 moves in first ply:
a3, a4, b3, Kf1, Kf2, Kg2, Kh2, Kh1

Should the black white king be at h1 ?

Greets, Thomas
