Ouarff, it is not dual-free. But according to Popeye, the following
12-variation is correct :

1.h2-h4 c7-c5 2.h4-h5 c5-c4 3.Rh1-h4 c4-c3 4.Rh4-c4 f7-f5
5.Rc4*c8 f5-f4 6.Rc8*b8 Qd8-a5 7.Sg1-f3 Qa5*a2 8.Sf3-e5 Qa2*b1
9.Ra1-a6 f4-f3 10.Ra6-h6 e7-e6 11.Rh6*h7 Sg8-e7 12.h5-h6 Se7-g6

The wrong 11-variation suggests, nevertheless, that 12 might not be the
infimum.
