FRUIT is not available for many years because it is new but it is certainly open source program. I think that second place for a program that is less than 2 years old and also open source is a great achievement for fabien. I think that Fabien is the best programmer in computer chess and he is clearly better than other programmers and the fact that fruit is free source code may push other programs to get better thanks to learning.
