With all my respect to Crafty and it's author,it's not the holy Bilble and everyone has the right to express his opinion and share his thoughts regarding the engine's performance.....

Opinions are like assholes. Everyone has one, and most aren't worth shit.

But.. everyone is aloud to express them.. especially after a good course of beans.. BRRRRAAAAAPPPP!!!

Loosen up dude this is not the Computer Dictators Club. How is asking "How come crafty does not enjoy the same improvement in strength as the commercial versions?" criticism?

Humans reach a plateau in strength and this could be the case with crafty. Considering that the source is open "should" mean that thousands of developers are eyeing the code and giving feedback to Dr Hyatt. Perhaps this is not the case.

Although many more games are required, the signs are promising that progressive improvement is being shown in recent times.
