I also had serious doubts about the strength of CM8000 at first. Most of them were caused by evaluation bugs in the Thinking Lines and Visual Thinking windows, as have been clarified in this forum and promised to be fixed in the patch next month. Reportedly they are GUI bugs only, not bugs in the chess engine itself. Now, after quite a few comparison tests between CM6000 and CM8000 using analogous personalities, my impression is that they are generally very similar. Except: CM8000 is generally faster to evaluate the same position, and seems less likely to "hang" on trivial lines during analysis. So I am inclined to think the CM8000 engine is stronger. Note that I did not say that I think the default CM8000 personality is stronger than the default CM6000 personality! That's tricky, because the time control is involved. The best personality for blitz play may be very different from what is best for long analysis in infinite mode. Of course this is all very subjective. WP
