Subject: a test position for computer programs(perpetual check)

Author: blass uri

Date: 06:32:49 05/30/98

the position:q5k1/4Q3/5r2/5P1B/6PK/8/8/8 white to move

Qxf6 leads to perpetual check begin with Qh1+
with 99968 Kbytes hash tables fritz5 found the draw after 32
seconds computing 9823 Knodes

Junior4.6 found the draw after 10 minutes and 21 seconds
and it computed 92,632 Knodes.

we see that the computers do not know what lines to compute
because I can see the draw by looking at less than 1000 nodes.

fritz5 is only very weak in this position while other programs I have
are weaker than fritz5.

is there a program that can see the draw
after less nodes than fritz5?
