Subject: Disadvantages of failsoft ?

   I was looking at the source of crafty and saw that on a fail low, the value
returned is alpha, rather than Max of all the values from the level below. Is
there some disadvantage in returning the real upper bound? I think it causes
some problems in Crafty making it much slower resolving fail-highs and fail-lows
at the root as these branches all need to be re-searched.
