What is your opinion? I tested only Junior5.9 and not Junior6[I do not get new versions from amir ban after I decided to stop helping him by telling him about bugs or about my ideas(I do not hate him and I also do not help other programmers)]. I did a nunn match against Fritz5 and Junior5.9(64 minutes/40 moves on p200MMX) and Junior5.9 won 12.5:7.5(Junior5 won only 11.5:8.5 in the chessbase games1 hour/game p233MMX) I also tested it in positions and gave it to play against other programs from some different positions but I did not test it in regular games. The value of the pawn of Junior is reduced and the result can be sometimes positive but sometimes negative. The negative news is that Junior5.9 cannot find the famous sacrifice that Junior did against Nimzo in WCCC. The positive news is that it is sometimes better in finding a sacrifce of a pawn or avoiding a bad trade. I believe that it is less than 100 elo better and even less than 80 elo better than Junior5 but I do not know. I have not the new book of alterman and Junior5.9 does not use tablebases. Uri
