I am wondering why do you trust test suites. They do not test the sucess in games but only success in test suites. There are many factors that are not tested in test suites. One of them is better time allocation. Another one is learning from previous search(programs that learn from previous search and do not clear their hash tables after every move can get better results in games but it is not going to help them in test suites). better book can also help. I think that the biggest problems are: 1)The fact that in test suites there is only one good reply when in practical cases there is more than one good reply. There is usually one bad move that turned out to be good in test suites and it is not the case in games. 2)The fact that the test positions were composed by humans and there are many cases when humans do not know the right move and these positions are not part of a test suite.
