As I said in an earlier post I'm not a programmer or even a good chess player. But I still keep coming back to the CD ROM as the problem. I don't know if Fritz uses Ken Thompsons database or what. Fritz does not do a normal "search" on this move. Fritz seems to read the CD ROM and then make the wrong move. The info which shows up in the move window indicates Fritz has incorrect information about the value of the moves in the move list. Where do these values come from? All moves have a score of draw so it does not matter which one it plays. Evidently the first move "generated" or looked at is f8=B and it plays that move. Fritz 5.32 with the Fritz 5.32 CD ROM does not play that move. It correctly has the score as (8) 1.f8=R. Why does Fritz play the move correctly with the new CD ROM but incorrectly with the old CD ROM? Fritz does not go back to a regular search routine untill after the f8=B move. So where does Fritz get the wrong idea that all moves are a draw? If this information does not come from the CD ROM then where? Please educate me so I can know better next time. Jim Walker
