I usually ask myself why many top commercial programs get hard to beat Crafty, or sometimes be betted. That is very amazing because we all could stand on the shoulders of "giant Bob", get benefit from his work, operate his Crafty, find out any weakness, chop any code to experiment or even "paste" to our programs. So I guess some following reasons (correct me if I am wrong or add more): - The top programmers never look into Crafty code (unbelievable); - Their programs never have any match with Crafty before (unbelievable); - They do not want to be "clone" of Crafty; they try to find other ways for their programs. Certainly, any new ways should be more difficult than common way; - They have to develop their own codes, pay much time and money to test them. On this point, the open source code program has much more advantage: many people with high knowledge and experience are helping Bob to test any new code, idea, find any bug, etc. quicker and better; - They could develop a program to beat Crafty, but it may lose most GMs or other programs. IMHO, Crafty has a good balance between many things; - Bob works for fun (as his statement), most of his time is for creativeness and for developing important functions of chess. In other hand, the commercial programmers work for their money. I know that most of time he has to support customers, develop user guide or many stupid functions. He could not have more time than Bob for creativeness and improvement of strength of their programs; - Bob works in computer chess much longer than us. With huge experience and knowledge, he could check, apply, implement any new idea / technique as quick (or quicker) as any commercial programmer. As a result, Crafty always applies the most important and latest things. The commercial programs have not enough advantage to win it; - Bob works harder than us ;-) Pham
