WEBVTT 00:01.080 --> 00:01.950 Hi there. 00:01.980 --> 00:07.770 In this lecture, we see Garry Kasparov playing against Viktor Kabakov in 1981. 00:07.800 --> 00:10.460 This is round one of the chess championship. 00:10.470 --> 00:13.560 So D4 from Kasparov we have the final. 00:13.560 --> 00:20.670 We go into the Queen's Gambit declined and it's the transformation in particular after G 396 Bishop 00:20.670 --> 00:27.060 g29561 cancels Bishop e seven and now detailed C five. 00:27.070 --> 00:29.040 This is a very theoretical approach. 00:29.190 --> 00:36.540 So White plays nine Bishop G five black holes was Knight C free D4 and now Bishop takes F six. 00:37.020 --> 00:38.700 This is an established mechanism. 00:38.700 --> 00:44.220 I've used this myself on occasion, giving up the bishop for the knight here and playing for 95. 00:44.220 --> 00:46.080 So one of the perks of this position. 00:46.080 --> 00:51.780 Well, a key defensive knight has been removed from the kingside, so maybe H7 seven is a softer spot 00:51.780 --> 00:52.680 than usual. 00:53.490 --> 00:59.100 We have 92 here supporting the five Knights, a six Rock C one. 00:59.100 --> 01:09.060 The bishop drops back to 87 nine C4 wrote the eight Knights f4 and here a very interesting B5 is played 01:09.150 --> 01:12.780 Queen six might be a little bit more solid. 01:12.960 --> 01:22.260 White overall is slightly better here but yeah B5 trying to generate activity here we have Knight d6y 01:22.260 --> 01:28.410 could have considered bishop take C6 but it looks as though why give black this counterplay in principle 01:28.850 --> 01:30.960 we're coming down to the seventh rank. 01:31.470 --> 01:34.740 The thing is, this position is favorable for White's Queen one. 01:34.740 --> 01:38.340 Let's say one gives up a two here and Bishop D5. 01:38.340 --> 01:46.080 There are pressure points like F seven and C eight converging if Bishop have five rook, C seven hitting 01:46.080 --> 01:54.270 a7 if Rook A1 trying to deflect the Queen away from c seven Queen C4 putting more pressure on F7 and 01:54.270 --> 01:57.810 one is actually significantly better if someone's going to drop like this. 01:58.140 --> 02:00.300 So that was an approach that was possible. 02:00.300 --> 02:08.790 But Kasparov chooses 96, so there's less counterplay here and still with 90 6c6 is targetted. 02:09.000 --> 02:14.670 So we have Queen 66 Rook take C six Queen the eight, Queen C two. 02:15.300 --> 02:21.740 So we do have some of the perks without Black having so much visible counterplay here. 02:22.590 --> 02:23.330 Some of the perks. 02:23.580 --> 02:25.260 White has some pluses here too. 02:25.260 --> 02:35.040 Look look out for so rookie ain't rook c one e5 and now Bishop D5 and this looks kind of ominous already 02:35.040 --> 02:42.240 as if Bishop takes f7, Czech and Queen St's might be actually tempting, and Black actually does provoke 02:42.240 --> 02:44.280 that in a way with Bishop Be6. 02:44.700 --> 02:48.570 So does Kasparov really want to take on F7 or is it just speculation? 02:48.570 --> 02:50.130 Queen B4 is played? 02:50.130 --> 02:54.870 If we look for a moment at Bishop takes f7 check, it is kind of dangerous. 02:55.200 --> 02:56.610 Queen STS 87. 02:56.610 --> 03:00.630 There are very interesting ideas like Rook g6 here. 03:00.960 --> 03:02.370 If d free. 03:02.820 --> 03:09.750 Let's just look at this because if rook gates Queen H five is also kind of a dangerous idea and Black 03:09.750 --> 03:11.220 could end up getting smashed. 03:11.460 --> 03:14.550 So yeah, there are some clear and imminent dangers here. 03:14.550 --> 03:20.580 So after 95 check Queen 87 and crashing through, there are some grave dangers. 03:20.580 --> 03:24.840 So let's say D free, though maintains D free. 03:24.870 --> 03:29.010 So at least Black's activated the bishop Queen G5. 03:30.410 --> 03:31.670 This position. 03:32.690 --> 03:39.110 Let's go with Rook takes B6 Rook seven changes to show that White has a strong attack after E4 and it 03:39.160 --> 03:41.450 looks as though this pawn super dangerous now. 03:41.780 --> 03:47.900 But yeah, engine suggests black might be okay and nearly okay with bishop at five. 03:47.900 --> 03:49.160 It's crazy stuff. 03:49.280 --> 03:58.460 This counter sacrifice is a good idea here because if Queen g6 Queen H four check and then white can 03:58.460 --> 03:59.990 play for five points. 03:59.990 --> 04:00.950 What would you play here? 04:02.240 --> 04:03.800 Yeah, we can win the queen here with Rook. 04:03.810 --> 04:06.110 Have seven check and then queen size. 04:06.110 --> 04:12.500 So let's assume this crazy move Bishop at five this position, Queen H six and white ends up with a 04:12.500 --> 04:13.400 small edge. 04:14.030 --> 04:20.300 Okay, so it's tempting, but I've actually preferred Queen B free hair. 04:20.300 --> 04:21.920 So this does look at F seven. 04:21.920 --> 04:25.820 And there is a very specific idea to put the Brooke on E seven. 04:25.820 --> 04:26.780 And now. 04:26.780 --> 04:34.310 Yeah, because one is going to e seven if rook f eight, then queen afraid the queen can just majestically 04:34.310 --> 04:36.920 come over here and cause trouble. 04:36.920 --> 04:41.090 So this position is going to be very pleasant for white indeed. 04:41.090 --> 04:42.590 There's a lot of pressure points. 04:44.160 --> 04:44.340 Okay. 04:44.540 --> 04:51.740 So let's, let's say Queen E eight, H four. 04:51.740 --> 04:53.870 Yeah, that's a nice position. 04:53.870 --> 04:57.710 But if we go back instead, Rook f eight say Rook half faints. 04:57.950 --> 04:59.210 Queen F three. 05:02.010 --> 05:06.310 A four queen H five queen in 8h4. 05:06.330 --> 05:08.340 Let's just have a look at this position for a moment. 05:08.640 --> 05:10.620 This is a bit passive with the look on her face. 05:10.650 --> 05:15.270 It does look very passive and it's going to have some interesting plans. 05:15.270 --> 05:17.400 Why it might even play on the Queen's side. 05:17.940 --> 05:20.730 So, yeah, this kind of play, it looks very dangerous. 05:20.730 --> 05:21.360 Blank. 05:21.600 --> 05:22.890 It's a different ball game. 05:22.940 --> 05:28.080 Okay, so 96 with ideas of Queen tanks, B five and hitting the rook. 05:28.410 --> 05:30.870 So here's just one fictional variation. 05:30.870 --> 05:38.820 But anyway, Rookie seven So the reason I've labelled that as an option to F eight is that on E seven 05:39.360 --> 05:46.530 there is a potential for white vacating D five and threatening 95 which hits the rook and hence the 05:46.560 --> 05:47.230 bishop. 05:47.250 --> 05:48.900 So this is what happens. 05:48.900 --> 05:55.320 This is a very powerful move now, and it also reserves the possibility not only vacating D five for 05:55.320 --> 05:59.700 95, it reserves the possibility of Bishop H five coming at this angle. 06:00.240 --> 06:03.770 So things are coming together on black's f seven soft spot. 06:03.780 --> 06:06.630 Here we see rook e5. 06:08.820 --> 06:16.290 Okay, so at least 95 is not with tempo, but now Bishop H five and here G six. 06:17.400 --> 06:24.600 So if the bishop dents go, if the rook rather dents go back, there's 95 and this is very unpleasant. 06:24.870 --> 06:31.140 So if rook d79 takes B six just winning material, if rook thinks there's rook st case. 06:31.740 --> 06:38.640 So yeah, this would be extremely unpleasant if rookie since 1966 again this position as Queen Zaitsev 06:38.640 --> 06:43.110 seven check and Rook take C six that's pretty crushing. 06:43.500 --> 06:49.020 So OC we have G six now there's a temptation to sacrifice. 06:49.020 --> 06:50.280 Is it sound? 06:50.550 --> 06:54.360 So this is really start of a vicious attack. 06:54.360 --> 06:55.530 That's the clue. 06:55.560 --> 06:57.330 So what would you play here? 06:57.330 --> 07:03.000 If I give you five sentence pause, video and know maybe work as deeply as possible from this position 07:03.240 --> 07:05.430 to justify any sacrifice made. 07:07.510 --> 07:09.580 Okay, so I'm about to reveal. 07:11.440 --> 07:13.400 Well, its pieces do seem optimal. 07:13.420 --> 07:18.440 That's a clue that maybe if if there is any time to do anything, maybe it's here. 07:18.460 --> 07:19.860 So Bishop takes G6. 07:19.960 --> 07:21.100 A whole bishop sacrifice. 07:21.100 --> 07:25.180 It is weakening the opponent's king significantly. 07:25.180 --> 07:27.660 So age tanks, rook tanks, G6, check. 07:27.670 --> 07:29.680 So here, F King 87. 07:29.680 --> 07:32.290 We're just coming in to F7. 07:32.530 --> 07:34.930 We're just crashing through f7. 07:34.930 --> 07:35.860 Thanks very much. 07:36.310 --> 07:39.340 So black's got a trend pretty carefully here. 07:39.640 --> 07:43.990 And the same with King H.A. Queen takes half seven is still very strong so. 07:43.990 --> 07:46.660 KING If eight King tries to flee towards the center. 07:46.870 --> 07:53.710 ROOK H6 And we have now King E seven if King G7 Hey, guess what we play. 07:55.430 --> 07:56.330 At some points. 07:57.010 --> 07:57.130 Yeah. 07:57.620 --> 07:59.570 We want to bring our best resources to the king. 07:59.570 --> 08:01.370 So Rook seven champ will do that. 08:01.370 --> 08:03.050 Bringing the queen to the king. 08:03.350 --> 08:04.750 And then the king gets mated. 08:04.760 --> 08:10.310 If King G ain't, we can play Rook c six this position. 08:10.490 --> 08:12.350 We can actually again bring the queen. 08:12.350 --> 08:13.850 Queen very near to the king. 08:13.850 --> 08:16.910 Can you see how at some points. 08:18.760 --> 08:19.090 Yeah. 08:19.120 --> 08:20.260 Rook check. 08:20.260 --> 08:23.370 And then if Rook G said we're playing Rook 87. 08:23.380 --> 08:28.570 Otherwise we're getting the queen right near the king controlling escape squares, igniting France like 08:28.570 --> 08:35.920 rook h6 If Queen G five knight G six check and we're winning the queen, it's crashing through if rook 08:35.920 --> 08:39.670 g5 her rook C6. 08:39.670 --> 08:47.080 This position is interesting, but White could sacrifice further to weaken the king further. 08:47.230 --> 08:50.220 And this position is just untenable for black. 08:50.790 --> 08:53.170 Black could see it try and counter p sac. 08:53.170 --> 08:55.480 But yeah, it's just an untenable position. 08:55.480 --> 08:58.420 It's just crashing through winning material. 08:58.870 --> 09:05.950 So the king went towards the center rook C6 anyway, so rooks controlling escape squares, but there's 09:05.950 --> 09:12.130 also key checking threats to factor in which we're about to see Rook F5 is tried. 09:13.390 --> 09:14.290 If IFOR. 09:14.290 --> 09:15.970 Can you see what one can do here? 09:17.560 --> 09:18.460 It's crushing blow. 09:18.730 --> 09:20.080 96 check. 09:21.160 --> 09:25.750 So if King Eights check, nine takes five and we're mating. 09:27.520 --> 09:30.660 And if King did something, it would just take only five. 09:30.670 --> 09:32.050 So that's pretty vicious. 09:34.360 --> 09:35.290 Otherwise. 09:35.290 --> 09:37.180 Yeah, it's dangerous for the back row. 09:37.210 --> 09:42.100 If the back row has opened up, this check is going to be really vicious. 09:42.700 --> 09:48.430 Rookie seven That rookie is stopping the king coming forward and we're getting a kind of back row mating 09:48.430 --> 09:49.960 possibilities or Queen F seven. 09:50.880 --> 09:56.020 Okay, so Rook five is tried and now queen free. 09:56.050 --> 09:59.560 The queen is coming over here, so it's worth playing a whole piece down. 09:59.560 --> 10:05.290 But he has faith that he has the advantage in a way, because of the King safety issues. 10:05.470 --> 10:11.050 The advantage is not just being up in material you can attack when there are king safety issues. 10:11.530 --> 10:13.180 The king is weakened here. 10:13.210 --> 10:16.150 There are many, many concrete threats to deal with. 10:16.360 --> 10:19.870 We see bishops C seven queen E for check. 10:20.680 --> 10:25.120 And here now we have rookie five. 10:25.300 --> 10:31.510 So guess what won't plays here, which kind of weakens the king a little bit further. 10:33.850 --> 10:35.920 Okay, 96 check. 10:36.730 --> 10:38.560 So it opens up that seven franc. 10:39.130 --> 10:43.060 The Kings push back on the back row, and now just Queen takes six. 10:43.570 --> 10:52.090 So with ominous threats and Black had to resign here, Black resigned if Rook have five to defend Queen 10:52.090 --> 10:54.820 F seven, Queen G seven check. 10:54.820 --> 10:58.330 And we have just a back row mate actually emerging. 10:59.110 --> 11:07.720 If Queen D seven here we can play rook H eight check and Queen F six is checkmate. 11:07.750 --> 11:10.540 Yes, it's a vicious position. 11:10.540 --> 11:17.080 So an amazing attacking potential shown in this transformation where there isn't a defensive knight 11:17.080 --> 11:17.800 on f6. 11:17.800 --> 11:25.720 Why seems to get glorious attacking opportunities and avoided an initial temptation actually just to 11:25.720 --> 11:26.860 take on h seven. 11:26.860 --> 11:32.380 So very interesting decision making moments in this game. 11:32.380 --> 11:39.880 This is very tempting, but it was rejected in favour of a very small maneuver with the bishop, so 11:39.880 --> 11:48.010 vacating D5 giving that 95 resource very, very suave maneuvers from Eric's POV in this game. 11:48.010 --> 11:48.820 A wonderful game. 11:48.820 --> 11:49.780 I hope you enjoyed it. 11:51.310 --> 11:54.100 Got some points from it so much.
