But I guess you already have to be a quite strong player in order to see these nuggets in a sea of weaker moves. I wasn't very impressed by the CS analysis done by Michael Markefka from the German go forum (http://www.dgob.de/yabbse/index.php?action=dlattach;topic=6039.0;attach=4930). Maybe its acceptable that it didn't found r8 and preferred q7 because r8 is not easy to see (should be a no brainer for 7d though) but that it preferred e.g. m3 over r2 keeps me wondering. Then at later points in the game it likes to peep at q7 at random times for no reason. It actually found that d15 is better than c15 which CS played in the actual game but instead of the deciding mistake b3 it suggests c9, which, while much better than the game since its not a total blunder, is clearly inferior to the Joseki move c7. Sure a strong player like Benjamin can distinguish between just bad and interesting suggestions and might learn from such analyses. But weaker players might end up confused and weaker than before. Note that I'm not singing in this strange chorus of disappointment over CS performance in the game against Haylee. I think it's way to early for todays computer programs (besides AlphaGo) to attempt even games against Pros. So not only the loss but also the way of loss was to be expected. I only want to put CS capabilities as a Go tutor in perspective. I suspect Aja is right and Remi should go the path of integrating the GPU even if it's just to get more "oomph" for CS. That he tried to learn GPU programming from scratch is a noble attempt but I guess it's just to ambitious to accomplish in a reasonable timeframe. Using one of the ready to use frameworks should make it feasible though.
