There are things in Junior that can be improved without changing the fact that it is a fast searcher. The evaluation function should be changed and my Junior5.4 has a different evaluation function. For example it is improved in avoiding the mistake of losing the bishop by Bxa7. There are also tactical mistakes that Junior can do not because of the fact that it is a fast searcher. It does not consider underpromotion. It is more important against humans who know this weakness because computer programs do not use evaluation function that assume that the opponent cannot do underpromotion. I found also other cases when Junior could not see simple tactics. Junior clears the hash tables after every move so it cannot learn from previous search and it is not because of the fact that it is a fast searcher. I know that Junior5.4 has a different evaluation function(probably better) and it is not slower. There are many things to improve also in Junior5.4 and again it has nothing to do with the fact that Junior5.4 is a fast searcher. It has more to do with the fact that Amir Ban is not living from developing Junior and has a full time job in M-systems. Uri
