Subject: perpetual check

Author: Robin Smith

The following position is a rather trivial (for a human) perpetual check.  Why
does it take some programs so long to see it?  Many of today's top programs
think White is winning, and after long searches too!  Which program detects
perpetual and returns a draw score the fastest?
