Hmmn - I have a totally different experience. When I run with ponder=ON on my single CPU Win98 system under Winboard (or under Xboard and Linux), I get about 50% CPU time for both programs (and the few programs I tried). Under the Fritz 6 GUI, playing Firz vs. Yace, Fritz gets 80% CPU and Yace 20% CPU. Running Tiger-Yace under CA6, Tiger gets 80% CPU and Yace 20% CPU. Yace does not lower its priority, nor does it try steal any CPU-cycles. This clearly shows, that on my computer, running under CB with ponder on is almost useless. Regards, Dieter
