Ah, yes, I see now that the search is broken.  I think the MPC code I copied in
must be pruning lines it should not be.  After forcing Qc2 Bd3, I got only this:

   9     1.76   0.05   5. Qxd3 Qxb2+ 6. Ne2 g5 7. b5 g4 8.
                       bxc6 gxf3 9. Kxf3 dxc6
   9->   1.77   0.05   5. Qxd3 Qxb2+ 6. Ne2 g5 7. b5 g4 8.
                       bxc6 gxf3 9. Kxf3 dxc6
  10     3.87     ++   5. Qxd3!!
  10->   4.62   0.44   5. Qxd3 Qxb2+ 6. Ne2 g5 7. b5 g4 8.
                       bxc6 gxf3 9. Kxf3 dxc6
  11     4.62     --   5. Qxd3
  11    10.96     ++   5. Qxd3!!
  11    17.37   1.02   5. Qxd3 Qxb2+ 6. Ne2 g5 7. b5 g4 8.
                       bxc6 gxf3 9. Kxf3 Rd8 10. Rg1+ Rg7
                       11. cxd7 Rxg1 12. Nxg1
  11->  17.37   1.02   5. Qxd3 Qxb2+ 6. Ne2 g5 7. b5 g4 8.
                       bxc6 gxf3 9. Kxf3 Rd8 10. Rg1+ Rg7
                       11. cxd7 Rxg1 12. Nxg1
<it failed low again at ply 13>

But after forcing Qd2, I get this:

 6     0.31   3.53   5. ... Qg6 6. Bh5 e5 7. Bxg6 Bxg6 8.
                     Qd5
 6->   0.47   3.53   5. ... Qg6 6. Bh5 e5 7. Bxg6 Bxg6 8.
                     Qd5
 7     0.54   3.47   5. ... Qg6 6. Bh5 e5 7. Bxg6 Bxg6 8.
                     Qd5 Re8
 7->   1.02   3.47   5. ... Qg6 6. Bh5 e5 7. Bxg6 Bxg6 8.
                     Qd5 Re8

So, right away I get a big plus for white.

Thanks. :)
