It is correct that free chess programs clearly make it harder for programmers to make money from chess engines but it seems to be also correct that free chess programs help to improve the level of the best programs. There was a long time with little improvement when shredder dominated and top programmers could not improve their program even by 50 elo per year and suddenly we find some programs that are better than shredder(rybka,commercial fruit and fritz and probably hiarcs and the toga1.1 that is based on fruit). It seems clear that at least part of that improvement is thanks to the free source code of fruit2.1.

I am sure that every program has the potential to become stronger. It is possible that null move pruning is not productive if you do different pruning and at least Junior does not use null move pruning. Uri
