Why?

People said again and again that it was impossible to search 18 plies brute
force with only futility pruning even with 200M nodes per second when Hyatt
insisted that this is what they did.

Now Hsu claimed that they only searched average 12.2 plies in his paper.

Hyatt was based also on the 200M nodes per seconds and we see that this number
was also a lie and with their efficiency the eqvivalent number in single
proccesor was clearly smaller.

Ed(the programmer of Rebel) already suspected some months ago that the number of
nodes may be wrong and we see that he was right about it.
