But given how fast Deeper Blue was, this is still a pretty good >result: Deep Blue was not 'faster' when expressed in search depth. Deep Blue, as we can see in its logfiles searched 10-12 ply. In 1997 that was a very big search depth if you realize they didn't use nullmove and did do a huge search in hardware. If you would let the Deep Blue from back then play now, then it would be about 2200-2300 rated now. In 1997 there was not much software that without too much of a forward pruning did get 10-12 ply. I remember how crafty even at 12 ply depth missed simple mates and how it had huge effort in those days to find moves like qxf4 in WAC 141. That was 3 ply in those days for DIEP to find. Deep Blue is very comparable to a tactical stronger gnuchess. Of course making gnuchess' evaluation function in hardware already is an incredible job. Hydra is programmed in FPGA. Though still very low level, that is not comparable to the programming of Deep Blue. It has been programmed in the hardware logics. So it ONLY works for that technology (0.6 micron technology) and it has been built with logic blocks. Try making a chess program with logic blocks! Then 2 weeks before the match takes place, it gets assembled and must face kasparov. That's *real real late*. No time to test. No time to remove bugs. It crashed several times against kasparov. If you try gnuchess 4.0 from those days and sit and wait until it gets 10-12 ply you'll realize how big of an achievement it was to get 10-12 ply with a full width search, only forward pruning in the hardware. But of course it's 2005 now. We cannot compare a car from 2005 with 1905 either. Hardware is tens of times faster now and has more RAM. Algorithms improved. Deep Blue searched without nullmove and without hashtables. That's like making a DSP without FFT algorithms. If you look to the games, they are ugly bad. What we see is how kasparov deliberately has made it more exciting, to in completely won positions play the most ugly move possible in the position (really 1800 rated moves) in order to keep the tension in the game. Always at the moment that kasparov is dead won, he's doing some idiot move to keep back the tension. Especially in opening. In normal games kasparov just *destroys* his opponents in opening. Against deep blue he starts with 20 beginner moves in some random opening no one cares about. Seirawan is very humiliating towards kasparov in his analysis with annotations like: "oh kasparov is not very experienced in this type of position as he never plays it, he will not know this simple strategic idea which every player from 2000+ in this opening realizes". You can read that for 6 games. Do you believe kasparov can play like a beginner for 6 games in a row? In 1 game it sure could happen. But when kasparov plays 6 games like a beginner, when we already knew before the match played that IBM threatened to stop the lucrative matches: "as kasparov wins in the end always too easily", then obviously something else happened there. Please note Kasparov already lost from computers back in 1989. That was against 20Mhz pc's or so. So his loss in 1997 was no big deal from his viewpoint, but after the match when all the publicity happened he started to realize what an idiot he had been towards the chess world in general. The match kasparov-fritz already was a way way higher level. Still kasparov did what he wanted to do, but it was obvious that this match was a far higher level. fritz-kramnik we saw how easily GM's can win if they want to. the last few games kramnik played were a deliberate give away to get the match straight. >New game, >R7/1r3kp1/1qQb1p1p/1p1PpP2/1Pp1B3/2P4P/6P1/6K1 w - - 0 1 > >Analysis by Deep Shredder 9: > >1.Qxb6 > ² (0.41) Depth: 1/2 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kf1 Qxc6 2.dxc6 Rc7 3.g4 > ± (0.97) Depth: 5/10 00:00:00 >1.Kh1 > ± (0.98) Depth: 5/10 00:00:00 >1.Kh1 Qxc6 > ± (1.14) Depth: 5/12 00:00:00 >1.Kh2 > ± (1.15) Depth: 5/12 00:00:00 >1.Kh2 Qxc6 2.dxc6 > ± (1.20) Depth: 5/12 00:00:00 >1.Kh2 Rb8 2.Qd7+ Kg8 3.Ra7 > ± (1.27) Depth: 6/14 00:00:00 >1.Kh2 Rb8 > ± (1.02) Depth: 7/15 00:00:00 42kN >1.Kh2 Rb8 > ± (1.02) Depth: 7/15 00:00:00 46kN >1.Kf1 Rb8 2.Qd7+ Kg8 3.Ra7 Bf8 4.Qe6+ Kh7 5.Qf7 Qe3 > ± (1.15) Depth: 7/15 00:00:00 49kN >1.Kf1 Rb8 2.Qd7+ Kg8 3.Ra7 Bf8 4.Qe6+ Kh7 5.Qf7 Qe3 > ± (1.15) Depth: 7/15 00:00:00 53kN >1.Kh1 > ± (1.16) Depth: 7/16 00:00:00 74kN >1.Kh1 Rb8 > ± (1.16) Depth: 7/17 00:00:00 102kN >1.Kh1 Rb8 2.Qd7+ Kg8 3.Ra7 Bf8 4.Qe6+ Kh8 5.Qxb6 Rxb6 6.g4 Kg8 7.Kg2 Rd6 > ± (0.98) Depth: 8/18 00:00:00 135kN >1.Kh2 Rb8 2.Qd7+ Kg8 3.Ra7 Bf8 4.Qe6+ Kh7 5.Qxb6 Rxb6 6.g4 Kg8 7.Kg3 Rd6 > ± (1.00) Depth: 8/18 00:00:00 140kN >1.Kh2 Rb8 2.Qd7+ Kg8 3.Ra7 Bf8 4.Qe6+ Kh7 5.Qxb6 Rxb6 6.g4 Kg8 7.Kg3 Rd6 > ± (1.00) Depth: 8/18 00:00:00 145kN >1.Kf1 > +- (1.46) Depth: 8/18 00:00:00 150kN >1.Kf1 Rb8 2.Qd7+ > +- (1.74) Depth: 8/19 00:00:00 187kN >1.Kf1 Rb8 > +- (1.49) Depth: 9/21 00:00:00 231kN >1.Kf1 Rb8 > +- (1.46) Depth: 9/21 00:00:00 236kN >1.Kh1 > +- (1.47) Depth: 9/21 00:00:00 285kN >1.Kh1 Qxc6 2.dxc6 Rc7 3.Ra5 Ke7 4.Rxb5 Ra7 5.g4 Kd8 6.Kg2 Kc7 > +- (1.56) Depth: 9/25 00:00:00 387kN >1.Kh1 Qxc6 2.dxc6 Rc7 3.Ra5 Ke7 4.Rxb5 Ra7 5.g4 Kd8 6.Kg2 Ra2+ 7.Kf3 Kc7 > +- (1.70) Depth: 10/20 00:00:01 468kN >1.Kh1 Qxc6 2.dxc6 Rc7 3.Bd5+ Ke7 4.Rg8 g5 5.fxg6 f5 6.Rh8 Kf6 7.Rxh6 > +- (1.69) Depth: 11/24 00:00:01 731kN >1.Kh1 Qxc6 > +- (1.44) Depth: 12/37 00:00:02 1430kN >1.Kh1 Rb8 2.Ra6 Qxc6 3.dxc6 Kg8 4.Ra7 Rc8 5.g4 Kf8 6.Kg1 Rc7 > ± (1.29) Depth: 12/39 00:00:03 1980kN >1.Kh1 Rb8 2.Ra6 Qxc6 3.dxc6 Kg8 4.Ra7 Rc8 5.g4 Kh7 6.Rd7 Bc7 7.Kg2 > +- (1.53) Depth: 13/26 00:00:05 2749kN >1.Kf1 > +- (1.54) Depth: 13/35 00:00:06 3377kN >1.Kf1 Rb8 2.Ra6 Qxc6 3.dxc6 Kf8 4.Ra7 h5 > +- (1.88) Depth: 13/35 00:00:06 3736kN >1.Kf1 Rb8 > +- (2.13) Depth: 14/38 00:00:09 5431kN >1.Kf1 Rb8 2.Ra6 Qxc6 3.dxc6 Kf8 4.Ra7 Rc8 > +- (2.38) Depth: 14/38 00:00:10 6290kN >1.Kf1 Rb8 2.Ra6 Qxc6 3.dxc6 Kf8 4.Ra7 Rc8 5.Rb7 h5 > +- (2.37) Depth: 15/43 00:00:14 8488kN >1.Kf1 Rb8 2.Ra6 Qxc6 3.dxc6 Kf8 4.Ra7 Rc8 > +- (2.55) Depth: 16/43 00:00:23 13865kN >1.Kf1 Rb8 > +- (2.30) Depth: 17/48 00:01:29 49964kN >1.Kf1 Rb8 > +- (1.80) Depth: 17/48 00:01:53 63109kN >1.Kf1 Rb8 2.Ra6 Qe3 3.Qxd6 Re8 4.h4 Qxe4 5.Ra7+ > +- (1.80) Depth: 17/50 00:03:44 119708kN >1.Kf1 Rb8 > +- (1.55) Depth: 18/51 00:06:48 210842kN >1.Kf1 Rb8 2.Qd7+ Kg8 3.Ra7 Bf8 4.Qf7+ Kh8 5.Ke2 Rd8 6.Qb7 Rb8 7.Qxb6 > ± (1.21) Depth: 18/51 00:10:02 313444kN >1.Kh1 > ± (1.22) Depth: 18/51 00:10:13 319327kN >1.Kh1 > +- (1.57) Depth: 18/51 00:10:19 322612kN >1.Kh1 Rb8 2.Ra6 Qe3 > +- (2.18) Depth: 18/51 00:11:44 370017kN >1.Kh1 Rb8 2.Ra6 Qxc6 3.dxc6 Re8 4.Ra7+ Re7 5.Ra5 h5 > +- (2.33) Depth: 19/51 00:12:24 391645kN >1.Kh1 Rb8 2.Ra6 Qxc6 3.dxc6 Rc8 4.Ra7+ Rc7 5.Ra8 Bf8 6.Ra5 Bd6 7.g4 Ke7 8.Ra8 > +- (2.36) Depth: 20/51 00:15:31 484941kN >1.Kh1 Rb8 2.Ra6 Qxc6 3.dxc6 Rc8 4.Ra7+ Rc7 5.Ra8 Bf8 6.Ra5 Bd6 7.g4 Ke7 8.Ra8 > +- (2.36) Depth: 21/54 00:19:48 608403kN
