I ran Junior5 and Fritz5.32 for almost three hours.  After more than 3 billion
nodes, Junior considered the position dead even and gave the following line:

Junior 5.0: 30...Rhe8 31.Rb6 Ra8 32.Rc6 Re2 33.Bc8 Ra7 34.Rc5 Qd1+ 35.Ka2 Rxc2+
36.Qxc2+ Qxc2+ 37.Rxc2 Nd7 38.Rc6 Ne5 39.Rf6 a5]

Unfortunately, I lost the Fritz analysis, but it was showing .6 of a pawn in
White's favor after its chosen move of Qc4.
