Thx for explaining. > >Jeroen ;-} If the evaluation is dependent in the initial position then the program is called a root processor. Fritz can trade queens when the evaluation is changed after trading queens not because of the fact that it can see more but because before trading queens Fritz believes that there is a king safety problem for white and after trading queens it suddenly understands that there is no problem because there is not enough material in the board. The problem is that Fritz has one evaluation for middle game positions and another evaluation for endgame positions. If the original position is a middle game position it does not use the endgame evaluation in the search and start to use it only when the position in the board is endgame position. Uri
