Did I get diddled when I bought my computer? It takes CM8K 28secs to solve
this on a 1.3Ghz P4. Or am I setting the thing up wrong to solve the mate?
Incidentally, the default CM personality is fastest, it seems, when it
comes to mate solving. I tried a couple of custom personalities, and they
were slower.
