On the actual comp that ran the game I get the following:

Junior 6.1 - Fritz 5.00
4k3/6Q1/2q5/3b4/1K6/8/8/8 w - - 0 1

Analysis by Junior 6.1:
90.Qe5+ Kd8
  =  (0.00)   Depth: 9   00:00:00  2kN
90.Qe5+ Kd8
  =  (0.00)   Depth: 12   00:00:00  66kN, tb=2
90.Qe5+ Kd8 91.Qh8+ Kc7 92.Qc3 Qxc3+
  =  (0.00)   Depth: 15   00:00:05  1904kN, tb=1340
90.Qe5+ Kd8 91.Qh8+ Kc7 92.Qc3 Qxc3+
  =  (0.00)   Depth: 17   00:01:06  29901kN, tb=9995
90.Qe5+ Kd8 91.Qh8+ Kc7 92.Qc3 Qxc3+
  =  (0.00)   Depth: 18   00:01:49  49072kN, tb=24705
