Steve: read the other responses carefully, as there is a lot of good info in them. I will add two comments. First, my Fritz 5.16 does backward game analysis, but it clears the hash tables between moves; I am told by CCC members that Hiarcs 7.32 does NOT clear the hash tables between moves, which I would guess would lead to a superior SYSTEM of game analysis (but not necessarily a superior result - - that will depend also on the evaluator, etc.). Second, for actual playing strength, the results between the two engines seem to be exceptionally close, based on a number of different competitions, and in spite of their different styles. Cheers, Mark
