Hello Terry,
My Century 4 does take untill ply 18.06 to find the right move at 3:09.  At that
point however it holds on untill way past 30 minutes.  This is on my Athlon 1.4
G machine with 200 M hash and Rebel hitting about 1.25M/nps.  After Kg4 and Be7
the machine must still avoid fxg5 and play Kf5 I think to make this a win.  Are
you sure you're using Century 4 and not Century 3.2?
Regards,
Jim
