> 7.Rb1xb7 Qd8-e8 8.Sc3-b5 Ka3xa2 9.Rb7xc7 Bf8-a3

> 10.Rc7xd7 Ba3-c1 11.Rd7xa7 Ka2-b1 12.Ra7xa8 Bc8-b7

> 13.Ra8-a1

One can achieve the same goal faster :

1.Pe2-e4 Pg7-g5 2.Re1-e2 Ff8-g7 3.Re2-f3 Fg7-d4
4.Rf3-g4 Cg8-f6 5.Rg4xg5 Th8-g8 6.Rg5-h6 Tg8xg2
7.Pe4-e5 Cf6-g4 8.Rh6xh7 Tg2xh2 9.Rh7-g8 Th2xh1
10.Pe5-e6 Th1-h8
