But we changed at the last second, yet after the tournament we re-ran this position so many times we stopped counting and it _never_ shifted off of Ne6. We later found parallel search bugs, but never found one we could _prove_ caused the change from Ne6. I haven't tried this position on Crafty.. but as I said, CB would probably have a tactical edge, Crafty would have a knowledge edge, particularly in endgames. I wouldn't be surprised if CB found some moves way quicker than Crafty, but I _would_ be surprised if the inverse happened. >one position doesn't say much but i think it is a good guess besides you've come >to similar conclusions years ago..... > > >Thankyou again Prof. Hyatt > >If you think of anything that may intrest me let me know
