Junior agrees but needs some hours on my pentium200MMX to find Qg3

If you divide the depth by 2 you get the full septh search of Junior5
if you multiply the depth of Junior by 2 you get the length of the longest lines
that Junior may consider.

I also found that Junior could probably win later by
61...Rg6 62.Qe5 b1N+ 63.Kd3(or 63.Kc2 Na3+ 64.Kb3 Qb1+  65.Qb2 Qxb2+)
63...Bf1+ 64.Kc2 Qf2+ 65.Be2 Qxe2+

Junior has no chance to see this line because Junior does not consider
underpromotions and cannot find b1N+
