Retro :

1.Rd1-d2 Nc1×Qb3
2.Rd2-d1 d7-d6 3.Qd1-b3 Nb3-c1+ 4.Qf2-g1 Nc1×Qb3(Qd1) 5.Qd1-b3 Nb3-c1+ 6.Qe1-f2
Nc1×Qb3(Qd1) 7.Qa4-b3 Nb3-c1+ 8.Qd1-e1 Nc1×Qb3(Qd1) 9.Qd1-b3 Nb3-c1+ 10.Qa6-a4 Nc1×Qb3(Qd1)
11.Qd1-b3 Nb3-c1+ 12.Qd6-a6 Nc1×Qb3(Qd1) 13.Qd1-b3 Nb3-c1+ 14.Qe6×d6(Pd7) Nc1×Qb3(Qd1)
15.Qd1-b3 Nb3-c1+ 16.Nc2-a3 d7-d6 17.Ne1-c2 Nc1×Qb3(Qd1) 18.Qd1-b3 Nb3-c1+ 19.Qe6-d6
Nc1×Qb3(Qd1) 20.Qd1-b3 Nb3-c1+ 21.Qa6×d6(Pd7) Nc1×Qb3(Qd1) 22.Qd1-b3 Nb3-c1+
23.Qa3-a6 Nc1×Qb3(Qd1) 24.Qd1-b3 Nb3-c1+ 25.Qc1-a3 (obviously we have to push
the bP in b column by c2-b3-a4 and b×Qa5(6) to open the cage with a×b5(Pb7). But
it's too early for 25... c×Qd6(Qd1)? 26.Qd1-c1 Nc1×Qb3(Qd1) 27.Qd1-b3 Nb3-c1+
28.Qa6-d6 Nc1×Qb3(Qd1) 29.Qd1-b3 Nb3-c1+ 30.Qa3-a6 Nc1×Qb3(Qd1) 31.Qd1-b3 Nb3-c1+
32.Qb2-a3 Nc1×Qb3(Qd1) 33.Qd1-b3 Nb3-c1+ 34.Qc2-b2 Nc1×Qb3(Qd1) 35.Qd1×Pc2(Pc7)
and there is no back's tempo to continue with 36.Qb2-b3 b3×Qc2(Qd1)+ 37.Qd1-c2
a4×Qb3(Qd1) 38.Qc2-b2 a5-a4 39.Qd1-c2 b6×Qa5(Qd1) etc. Where to find the
missing tempo ? Yes, the bP must help the wPh2 by g7×h6(Ph2) and the missing
tempo appears with h2-h1(B)!!

So : 25... e×Qd6(Qd1) !! 26.Qd1-c1 Nc1×Qb3(Qd1) 27.Qd1-b3 Nb3-c1+ 28.Qe6-d6 Nc1×Qb3(Qd1)

39.Qa6×Pf6(Pf7) Nc1×Qb3(Qd1) 40.Qd1-b3 Nb3-c1+ 41.Qa3-a6 Nc1×Qb3(Qd1) 42.Qd1-b3
