Subject: A note about Rybka's "speed" and variation display

It seems to me that Rybka's seemingly slow speed is caused by not counting
quiescent nodes as search nodes.

You can observe that Rybka's nodes per second drops dramatically in positions
where there are lot of forced check sequences.

I am actually pretty sure of this because of 2 reasons:

1) it never displays the parts of the variation coming out of the quiescent
search
2) it can solve mates with an unrealistically small nodecount
