This is the line that your Shredder 7.04 evaluates -0.18 after 27:54 minutes of search: 1.Qc4+ Bf7 2.Qc7 Rc8 3.Qxa5 Kh8 4.Rc7 Bxb3 5.Rfc1 Qxc1+ 6.Rxc1 = (-0.18) Depth: 15/47 00:27:54 241582kN and his line was 00:01:28.7 0.09 14 65827734 Qc4+ Bf7 Qc7 Rc8 Qxa5 Bxb3 a4 So Shredder would play the move 1.Qc4+ for the wrong reasons.
