Using the same CM6000 CMKing+ Settings at 30 sec per moves:
evaluation +2.56 pawns for white
Main line starting with 24... Qxb4 25. Qxd5 Rxe1 26. Nxe1 Re8 27.Qf5 Rxe1+
28. Kh2 Kg8 29. Qd5+ Kh8 30.Qf7! Qc4 31. Qxf8+ Qg8 32.Qxd6 this is why Shredder
selected 24...Bc4 instead of losing with the other variation.
