You complain about hiarcs book using the line using 8.......f5. You have white. If you use the book at it's best settings the move f5 would never be played. That is to say tournament book on variety of play to minimum. Remember variety is set higher so that you have more variation with the book. Mine I just realize may not play it due to book adjustments (learning) however I have tried to get mine to follow this line a 100 times and it won't. To attempt to carry on a little further. 9. Nd6...Bxd6 10.exd...Now it gets strange since 10...Qb6 is still book. Yet if I buy into what you are telling me Hiarcs here I must assume played 0-0. 11.Be2...Qb6 12.c4....Nf6 13.0-0. And that this is the final position you complain is so bad for black. So what do we have mistaken moves posted, complaint about book but not used to it's optimum playing strength, with 10....?? I must assume another mistaken posted move, then finally last but by no means least a final position that leaves white less then 0.5 of a pawn up. As for the complaint about the bishop's opening again I would suggest you change your book settings however that was also dealt with in another thread. To deal with your specific questions I was rated at 2140 a couple of years ago, prior to other committments. I do play against my programs but it would be true to state that I handicap them normally either by turning down there rating then playing an even timed game or by allowing the program less time than I normally 10 minutes for it and 2 hours for me. I normally do not play any program until I have seen it play a considerable amount of games at which point I feel I have more of an idea of it's style. I use computers as an analysis tool and to play over games played by others. Thanks. Sarah.
