Only because Anand made a little bit PR for ChessBase you >believe that? No It has nothing to do with anand. The point is that search help not only in tactical positions. programs have some positional understanding in their evaluation and if you combine the positional understanding with deep search you may get good moves in most quiet positions. > > > >>In minority of the positions they perform like 1700 players or worse but it is >>hard to get them in practical games. > > >How do you know? Eduard Nemeth knows some dozens or more variations to get a >program into helplessness, of course 3000 tactical ON! But still the progs lose >like 1700. Could you explain it? Let me help. Real masters simplx don't like >such play. Ergo, they don't train. And that gives you the impression you >described. Nemeth lose more games than he wins and analysis of his wins show that usually the programs do not do the same mistakes at long time control on fast hardware. I am sure that GM's can beat programs by wrong sacrifices if they want to do it but they will lose more games by this tries before they get their win. If they did not plan all the game before the tournament this is a big risk to play wrong moves and it is better for hem to play for a draw against the computer and not to try to win with probability of 10% by Nemeth's way when there is 90% probability for a loss. > > > > >> >>computers already performed better than 2400 in the israeli league when the >>teams had the right to choose the human to play against the computer so they >>could choose humans who are relatively better against computers. > >So you accept that training helps.

Just >average competition without the show character. Fabulous. Could I visit Israel >without fear to be killed in the war? I live in Israel and I do not feel afraid of being killed. I cannot be sure that nothing will happen but statistics tell me that accidents between cars kill more people than the terrorists. I know that statistics tells me only about the past and not about the future but if you do not assume that things will be different in the near future you should be afraid more of being killed by other reasons and not by terror even in Israel. > >Finally: Are you Mendi Bael?
