I am giving a large bonus for the connected passers but also added a (very simple) eval term to recognize when a passer will queen and survive... I already am using a square-control mechanism to assess control of the square in front of the passer. Now I just say if the passer is on the 7th rank and its side has the move give a big bonus. >Secondly important is to do promotions in qsearch for this >position. Do you? Yes I have promotions in qsearch. >If you do then with that check extension added it should be 14 ply >this combination. Thanks for the ideas. I am going to think about how to extend or add knowledge to eval to handle this type of position. Scott
