The Crazy Bishop, using about 64mb hash.  For what it's worth, to get TCB to
generate a log, add something like this to it's .cui file, and it'll write a log
to whatever filename you come up with:

logf bishop.log

The Crazy Bishop wasn't interested in showing the actual mate for some reason,
but it was clear to me that it did indeed SEE the mate:

After which I believe Black's only move would be 7....Kc7 and then 8.Qc8# ends
everything.
