Your eval was positive here?  I looked at this a while and concluded black is
probably losing.  I sicced crafty on it for a while and it failed low at every
iteration.  After 13 it was -1.61...  at 14 it was -2.10, at 15 -2.25, etc...

what did DJ see to produce a + eval?  I am searching the position after 28. Bxf7
which is what Crafty had for the best move for white by far...

I get almost 0.00 here after a few seconds...  It doesn't seem to improve with
depth.

Here I get a pure draw score.

He must have overlooked the consequences of the check with queens still on?
Crafty is at +1.0 here

Obviously hopeless here. I get +8 after 1 second.

Well done.  It looked dicey at the beginning...  Goes to show that "it ain't
over till it is over" against humans...
