What happened was that I rewrote/simplified this code a bit, and when testing
it I noticed that on odd occasions after doing the IID stuff, I _still_ had no
move to try.  I put that message in while debugging.  The reason this happens,
is that it is possible that at the current ply (where there is no known hash
move) the side to move is mated, or it is a draw by repetition or stalemate.

When I continued to get that message, I finally figured this out, but forgot to
remove the message.  You can ignore it as nothing is wrong at all.
