In friend mode, the engine send to the chessbase interface different variation
line with evaluation of the current position. The interface, choose a variation
with an evaluation that is equal to the best evaluation minus the handicap that
you can see when you start fritz in "friend mode".
If you play with a positionnal engine, the evaluation of the position will be
calculate with parameters like open line, passed pawn etc... If you play with
pure tactical engine, the position will be calculate with the values of the
figures (pawn=1,rook=5 ...).
So a positional engine will have an evaluation of the position larger than a
tactical one. Choose a "bad positional handicap variation" will be best than
choose a "bad tactical handicap variation". Do you understand ?
