Hello, Another way to prove it retains the hash tables is to turn off the permanent brain (Pondering). Then when playing a game, notice the depth of search and how long it takes to finda a move. When you play a move you will notice that Hiarcs does not start it's search a 1 ply but may start its search at 5/8 or something like that with 00:00:00 time showing taken for search. This indicates it is using information from a previous search stored in the hash tables. This is why Hiarcs has an advantage in engine/engine testing. The Pondering is turned off for both engines but since Hiarcs does not reset it's hash tables it has information left over to start the next search. But notice it's opponents (Fritz,Junior,Nimzo) have to start every search from ply 1 even when the predicted move is made. Jim Walker
