Originally created at the time, when CM 4.000 was the standard release of MINDSCAPE. There were 2 parties working on this parallel - on one side, Mr. Walter PILZ, and the other side were the 2 old, but very reputated comrades H.J. Schuhmacher and Huber BEDNORZ ( Aachen and Colgne, Germany ). These gents were, BTW, the founders of the valuable BT ( BEDNORZ / Freddy Thönnisen ) - and later BS = BEDNORZ / Schuhmacher test series. They were 1st given to publik in the Austrian Chess Computer mag PC SCHACH 1/ 1995 as the Version b. Last metiones settings came out a couple of weeks earlier than the Mr. PILZ settings. These, however, did a good job in CM 5.000, not so good in CM 5.500 anymore and sure are NOT close to the original gameplay of the engine in it's existing form, 2.61. Here's the reason why : CM 6.000, from what I've tested, roots back noticeable to the fomer gameplay of CM 4.000 - which means, it's designed to play very active against the opposite King, weak pawns and weak fields. The setting " King safety 170 " slams on the brake of this engine, it's far too high, the engine is advised by setting, to play more " carefully " - and this contradicts to the origin. So, it somehow plays " constructed, unnormal " moves, so to say. For your convenience, I repeat the original BEDNORZ settings : Attacker / defender +3; Strenght of Play 100; Randomness of Play 0; Book depth 0 Selective search 10, Contempt for Draw 0,0 Positonal : Materail / Position -3; Control of Center 103; Mobility 103; King safety 133, Passed pawns 100, Pawn Weakness 133 Material : Own Queen 9,2 (!) Opp.Queen 9,0 rest original This, to prevent exchange willingness, if it ain't a countable benefit. CM got no probs to exchange Queens early..... I had them in thest series - they work out fine - and sure are worthy a solid testing, if one is interested in this. To ask something, one doesn't understand - and doesn't have the backgroung info - is GOOD, never ignorant. THIS is the purpose of a NG, and I really wonder, why all our approved experts didn't answer you. Never mind : as far as Mindscape is concerned, they just stick to a somehow " neutral setting " originally. Same as the original settings ttable_size=20 - in the remaining relevant .ini's for this in CM 6.000, the cm.ini and the cmdefalt.ini. This prevents, that somebody with little knowledge " kills " the prog by setting too high values, comparing to his own system ressources. If this is of interest for you, here's the way : BOTH .ini's must have the same (!) value, of course. The general rule her is : 1 count more means allways a doubling of the table size. Example : 20 = 1, 21 = 2, 22 = 4, 23 = 8, 24 = 16, 25 = 32, 26 = 64 ( MB ). CM is NO prog, who basically needs alot of hash tables, it is NO brute force searcher. For Blitz 4 MB. for tournament gameplay 40 / 120 I suggest 16-32 MB as just fine, for overnight analysis 32 - 64 MB....allways keeping your RAM in total in mind, to prevent swapping. Hope, this helps ELVIS
