Their is a weird account at ICC called DeepViolet. The facts about it: a) the operator is a nice fellow b) when it entered icc many years ago it had the same rating like scratchy (deep blue). didn't go up much since then. c) i have not seen it lose because of tactical mistakes yet, so tactical it's at ferret level. d) it makes the weird deep blue Bxg3 mistake, yet plays very strong further e) its rating is way higher than zarkovx (which has not only a high similar style as deepviolet, but from experiments also plays positional similar to deep blue). f) finger says deepviolet plays at a PII-266. operator told me PII-333, and updated recently his finger. ZarkovX runs unattended at a K6-3 at 475Mhz. zarkov runs way faster on a K6 than on a PII at same speeds. This K6-3 at 475 is for crafty though and for DIEP exactly as fast as a PII-450. For zarkov it's more like a PII-650Mhz. g) operator needs 18 seconds increment, a level which is only needed if you are way older than 75 or operating hardware or a parallel system. Operators of Rebel use 8 seconds a move (very seldom 9 seconds). operators of windows programs use 4 seconds a move (this all loss because of operating). h) he already plays for years 2 18. a very consequent man this operator. fingering scratchy: Information about scratchy(C) (Last disconnected Wed Mar 13 1996 19:25): rating [need] win loss draw total best Blitz 2871 [8] 141 1 4 146 Standard 2781 [6] 374 14 37 425 1: Meow.

Bf4 a5 19. Qb3 {Game courtesyadjourned by White} The 16..Bxg3 move was funny and quite laughable. DIEP doesn't even *consider* bxg3 of course. I tried several ZarkovX versions: don't even *consider* Bxg3 either. Now this bxg3 gets made by more programs, i don't know why actually, it's a beginnersmistake in chess. Giving up the bishop pair AND giving white a nice g3 pawn. Now let's get to a game fragment DeepViolet - other program 1. d4 (0:05) Nf6 (0:06) 2. c4 (0:05) g6 (0:04) 3. g3 (0:05) c6 (0:04) 4. Bg2 (0:07) d5 (0:04) 5. cxd5 (0:06) cxd5 (0:04) 6. Nc3 (0:07) Nc6 (0:04) 7. Nf3 (0:27) Bg7 (0:06) Weird, but not all programs play Nf3 8. O-O (0:19) Ne4 (0:10) 9. Bf4 (0:39) O-O (0:09) Most prefer Bg5 10. Rc1 (0:25) Be6 (0:06) 11. e3 (0:29) f6 (0:39) e3? the opponent of deepviolet would have made the same mistake 12. Qb3 (0:29) Qd7 (0:31) 13. h4 (0:07) h6 (0:12) 14. g4 (0:33) Rad8 (0:44) 15. Rb1 (0:38) g5 (0:28) Now this is a weird move 15. Rb1. it's laughably bad. it's not a tactical blunder though. I see junior at huge depth get to the same move. Zarkov is the only program that could reproduce this move, but deepviolet definitely isn't zarkov at a PII-333. It isn't zarkov at all. 16. Bh2 (0:24) Rf7 (0:46) 17. Rfc1 (0:33) Bxg4 (0:25) 18. Nxe4 (0:37) dxe4 (0:10) 19.

Kg1 (0:11) Bb5 (0:32) etcetera of course white lost it So i give here 4 moves: 16..Bxg3? 7.Nf3 9.Bg5 15.Rb1 I haven't found a program yet that makes all those moves in blitz, or a minute later. Can someone try all his programs at home at these 4 positions and see whether these 4 moves get the mainline. I like to solve this deepviolet mystery. It is not zarkov 4.5 4.0 diep fritz junior wchess genius 6.0 So what softwareprogram/hardwarecomputer is it then?
