I think you work too hard to draw an artificial distinction. First, I like the sacrifices that CST comes up with. It takes a plain position and turns it into a tactical mess via a startling sacrifice or series of sacrifices. Sometimes it is wrong and loses, other times it is right and wins. I think it is a mistake to get hung up about the possibility that it will make a mistake, and I want to make sure that I am not coming down on that side. It plays like its namesake, and what could be better than that? Especially if the target opponent is human. If someone wouldn't be delighted to have a computer program do that kind of thing against them, they need to go play checkers or something. This kind of thing should amuse you greatly (I don't think that programs do this enough), stretch your defensive resources (which programs don't tend to do very much at all), and give you ideas about how to do that kind of thing yourself (which programs don't tend to do at all). If the target opponent is a computer, it sort of depends upon what your goal is. If you don't want to lose, this is probably not the best way to play. I have to believe that some of these sacrifices can be defended easily, causing the program to "lose chanceless", as Vincent would say. So I hope that I have indicated to you that I am a CST fan, even though I am not a fan of Chris' personal behavior. I hope that I have also indicated that I don't think that boring chess is the best chess. I think though that this kind of stuff can be challenged and explored without pooping the party completely. In my opinion it is not enough to play this kind of thing. There should be some sense behind it, and if anything is to be applauded as a brilliancy, there should be something substantial behind it. I suppose it comes down to whether the program knows anything here other than that it wants to open lines, get passed pawns, and win a pawn or two for the exchange? A couple of points. It is unlikely that a program will refuse the sacrifice, but I wonder what happens if one chooses to do so. Superficially black seems to be fine to let it sit there. Assuming that the sacrifice is accepted, 45. a5 seems easy to find, but I wonder what would have happened had black tried to keep lines closed with 45. ... b5, which is also possible for a program to find. bruce >is there any chess program playing Rc6 ? > >brilliant. i hope more will follow. >because this steps into a new quality in computerchess. >the moment when chess programs BELIEVE !!!! instead of knowing. >or seeing in the tree. > > >43.Rc6 Nxc6 >44.bxc6 Rc7 45.a5 bxa5 46.Qe2 a4 47.Qb5+ Ka8 48.Qxa4 Qf6 49.Qa5 Qe7 >50.Re2 Rdc8 51.Rxe5 Qg7 52.Qe1 a6 53.Qe2 Rxc6 54.Re7 Qc3 55.Kh2 Qb4 >56.Ra7+ Kb8 57.Qe5+ R8c7 58.Qh8+ Rc8 59.Qxh4 Rc1 60.Bf2 R1c6 >61.Qg5 R8c7 62.Qg8+ Rc8 63.Qg7 R8c7 64.Qh8+ Rc8 65.Qe5+ R8c7 66.h4 Rc2 >67.Bd4 R2c4 68.Qe8+ Rc8 69.Qe4 R8c6 70.Rd7 a5 71.Be5+ Ka8 72.Rd8+ Ka7 >73.Qh7+ Ka6 74.Rb8 Rb6 75.Ra8+ Kb5 76.Qd7+ Rcc6 77.Bc7 Qe1 78.Re8 Qxh4+ >79.Kg1 Qf6 80.Re5+ Kc4 81.Bxb6 Qxe5 82.Qxc6+ Kb3 83.Qe4 Qa1+ >84.Kf2 Qb2+ 85.Qe2 Qxe2+ 86.Kxe2 a4 87.Kd2 a3 88.Ba5 a2 1-0 > >typical for this forum that nobody registers. > >i guess the nimzo-team has registered it. >maybe chrilly himself, when he was in leiden knows about.
