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) 29.Qd1-b3 Nb3-c1+ 30.Qa6×e6(Pe7) Nc1×Qb3(Qd1) 31.Qd1-b3 Nb3-c1+ 32.Qa3-a6 Nc1×Qb3(Qd1) 33.Qd1-b3 Nb3-c1+ 34.Qc1-a3 f7×Qe6(Qd1) 35.Qd1-c1 Nc1×Qb3(Qd1) 36.Qd1-b3 Nb3-c1+ 37.Qf6-e6 Nc1×Qb3(Qd1) 38.Qd1-b3 Nb3-c1+ 39.Qa6×Pf6(Pf7) Nc1×Qb3(Qd1) 40.Qd1-b3 Nb3-c1+ 41.Qa3-a6 Nc1×Qb3(Qd1) 42.Qd1-b3 Nb3-c1+ 43.Qc1-a3 g7×Qf6(Qd1) 44.Qd1-c1 Nc1×Qb3(Qd1) 45.Qd1-b3 Nb3-c1+ 46.Qg6-f6 Nc1×Qb3(Qd1) 47.Qd1-b3 Nb3-c1+ 48.Qa6×Pg6(Pg7) Nc1×Qb3(Qd1) 49.Qd1-b3 Nb3-c1+ 50.Qa3-a6 Nc1×Qb3(Qd1) 51.Qd1-b3 Nb3-c1+ 52.Qc1-a3 h7×Qg6(Qd1) 53.Qd1-c1 Nc1×Qb3(Qd1) 54.Qd1-b3 Nb3-c1+ 55.Qh6-g6 Nc1×Qb3(Qd1) 56.Qd1-b3 Nb3-c1+ 57.Qg6×Ph6(Ph7) g7×Ph6(Ph2) 58.Qa6×Pg6(Pg7) Nc1×Qb3(Qd1) 59.Qd1-b3 Nb3-c1+ 60.Qa3-a6 Nc1×Qb3(Qd1) 61.Qd1-b3 Nb3-c1+ 62.Qc1-a3 f7×Qg6(Qd1) 63.Qd1-c1 Nc1×Qb3(Qd1) 64.Qd1-b3 Nb3-c1+ 65.Qf6-g6 Nc1×Qb3(Qd1) 66.Qd1-b3 Nb3-c1+ 67.Qa6×Pf6(Pf7) Nc1×Qb3(Qd1) 68.Qd1-b3 Nb3-c1+ 69.Qa3-a6 Nc1×Qb3(Qd1) 70.Qd1-b3 Nb3-c1+ 71.Qc1-a3 e7×Qf6(Qd1) 72.Qd1-c1 Nc1×Qb3(Qd1) 73.Qd1-b3 Nb3-c1+ 74.Qe6-f6 Nc1×Qb3(Qd1) 75.Qd1-b3 Nb3-c1+ 76.Qa6×Pe6(Pe7) Nc1×Qb3(Qd1) 77.Qd1-b3 Nb3-c1+ 78.Qa3-a6 Nc1×Qb3(Qd1) 79.Qd1-b3 Nb3-c1+ 80.Qc1-a3 d7×Qe6(Qd1) 81.Qd1-c1 Nc1×Qb3(Qd1) 82.Qd1-b3 Nb3-c1+ 83.Qd6-e6 Nc1×Qb3(Qd1) 84.Qd1-b3 Nb3-c1+ 85.Qa6×Pd6(Pd7) Nc1×Qb3(Qd1) 86.Qd1-b3 Nb3-c1+ 87.Qa3-a6 Nc1×Qb3(Qd1) 88.Qd1-b3 Nb3-c1+ 89.Qc1-a3 c7×Qd6(Qd1) 90.Qd1-c1 Nc1×Qb3(Qd1) 91.Qd1-b3 Nb3-c1+ 92.Qa6-d6 Nc1×Qb3(Qd1) 93.Qd1-b3 Nb3-c1+ 94.
