1)It seems that Ed missed the following post http://www.talkchess.com/forums/1/message.html?274444 2)I have questions about the recapture extensions. a)I think that it is more simple to use HIGH = root_score+TABLE [current_depth]; static int TABLE 500,500,450,400,350,300,275,250,225,200,200,.... By this way you do not need to update high every ply but only calculate it after recapture. b)What do you mean by I_score Is is the score after the recapture or before the recapture. I think that it may be productive if you demonstrate by a diagram what is the value of I_score. suppose you search from the opening position 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nc6 Bxc6 dxc6 I guess that a recapture extensions is done. Assume that the initial position has 0.00 evaluation. What is the value of high?(I am not sure if 2.5 or 2.25) Ignore the fact that bishop and knight may have the same value. Is piece_value depth the value of bishop or knight when the recapture extension is done(I guess bishop)? Is I_score the score before dxc6 or after dxc6? Is I_score from the point of view of the side to move or from the point of view of the opponent? Uri
