This is correct; just make sure that you've edited the file chssbase.ini to reflect the fact that the tablebases are now on the hard drive. >Presumably Hiarcs7.32 does this >automatically when a tablebase position is reached, though it sounds doubtful to >me if it can just change engines on the fly. When a tablebase position is reached, the Hiarcs engine itself accesses it without a change of engines (this is why you get the message "Initializing tablebases" when you load the Hiarcs7.32 engine). I recommended using Tablebase 1.0 for positions you set up yourself because A) I've had better results with it and B) I *think* (and this is a surmise based on the behavior I've seen -- take this with a pinch of salt) that the Hiarcs7.32 engine needs a move or two "warning" before accessing the tablebases -- in other words, the tablebases didn't appear to be accessed when I set up a tablebased position and used Hiarcs7.32 for analysis of it, but when I created a position a move sooner (in which a tablebased position was reached after an obvious capture), the Hiarcs7.32 engine accessed the tablebases with no problem. The Tablebase 1.0 engine *always* accessed the tablebases when I set up a position that I knew was in one of the tablebases. Of course, all of this could easily be due to my own stupidity or some sort of hardware problem so, as I said, take this with a pinch of salt.
