c)58...Qa3(4.19/13) 59.Ra7
d)58...R1c2(4.25/12)



2)57...Qb1 58.Kh3 b5 (2.72/13)(next best Qc2 fails low at depth 13) 59.Qf2(fails
high at depth 13)
3)57...Qc2 58.Rb7(3.22/12,3.50/13)
4)57...R1c2 58.Rg7(3.13/12,3.41/13)
5)57...Qc3 58.Ra7(3.44/12,3.72/13)
6)57...Qa3 58.h5(3.38/11,4.28/12)
7)57...Kg8(+-4.78)
8)57...Qd2(+-4.97) 58.Bxd2
