I get the following:

New position
1q5k/p3K3/3r4/1Pp2Q1p/4R3/8/P3P3/8 b - - 0 1

Analysis by Gandalf 4.32f:

1...Qc7+ 2.Kf8
  =  (0.09)   Depth: 1   00:00:00
1...Qd8+
  =  (0.06)   Depth: 1   00:00:00
1...Qd8+ 2.Kf7 Qg8+ 3.Ke7
  ³  (-0.32)   Depth: 1   00:00:00
1...Qd8+ 2.Kf7 Qg8+ 3.Ke7 Rh6
  ³  (-0.40)   Depth: 2   00:00:00
1...Qc7+
  ³  (-0.43)   Depth: 2   00:00:00
1...Qc7+ 2.Kf8 Rd8+ 3.Re8 Qg7#
  -+  (-#3)   Depth: 2   00:00:00
1...Qc7+ 2.Kf8 Rd8+ 3.Re8 Qg7#
  -+  (-#3)   Depth: 3   00:00:00
