So the question can be re-phrased, do you believe that the decision to stand pat in quies should be based on a different score than is used for various pruning decisions in the main search? Using methods (B) or (C) would imply this. If so, why?


You use the same score everywhere with both methods (A) and (B), you just have to adjust margins. If you include tempo bonus in evaluate(), all your margins (used for 'various' pruning decisions in the main search) are offset by that value.


I notice that Critter evaluates symmetrical positions near the opening as +.05. If you don't give a bonus in evaluate but only use the bonus for stand pat decisions, what accounts for the displayed .05 score? Is it purely something added for display purposes only?


Please give a specific example. Without knowing the position I can only say that most probably it is exactly because of the reason you stated. (Tempo bonus is added to the stand pat score).
