Hello Mark, This is what I just found at the ChessBase site in Germany under Hiarcs 7.32: "Hiarcs is the first ChessBase-compatible engine to fully retain hash tables between seaches. This improves performance in practical games. Even more important is the effect on game analysis..." It would appear from the above that Hiarcs does retain hash tables between moves. It would be very nice to see this in the info window. Hiarcs 7 and Fritz 5.32 show hash table info on the screen - why not Hiarcs 7.32? Also, I think that hash table info would be of some practical use for people wanting to experiment with the amount of megs allocated for HT in Hiarcs. By the way, I believe you have Rebel 10 and so do I, do you find as I do that Rebel's evaluation score is more accurate on a consistent basis than Hiarcs 7.32?
