A few points 1)Even in Chessmaster GUI, CM 9000 does not probe tablebases in search. It can only use them when the positions covered by the tablebases are reached. 2)In Chessbase GUI, whenever a position covered by the tablebase is reached, the GUI takes over. This is regardless of the fact that the engine has tablebase access 3) Given 1)+2) , CM9K doesnt lose anything when used in Chessbase GUI. 4) Tablebases probably result in a very small (if at all) increase in strenght. A minority are of the opinion that in certain positions, probing the tablebases can even weaken play. >What do your test results tell us?
