WEBVTT 00:01.140 --> 00:01.980 Hi there. 00:02.010 --> 00:05.640 In this lecture, we see Anatoly Karpov playing against the answer Yusupov. 00:05.640 --> 00:10.320 In 1988, the 55th US championship round nine. 00:10.320 --> 00:13.980 So C four from Karpov e69c3d5. 00:13.980 --> 00:17.730 So it transposes from an English opening into a Queen's Gambit declined. 00:18.060 --> 00:21.030 So we have 93 here from Karpov, nine of six from Yusupov. 00:21.060 --> 00:22.230 C takes D five. 00:22.230 --> 00:23.490 So the exchange variation. 00:23.490 --> 00:24.600 Bishop G five. 00:24.630 --> 00:25.590 C six. 00:25.890 --> 00:27.240 Queen C two. 00:27.810 --> 00:28.690 And now G six. 00:28.690 --> 00:35.370 So this does support Bishop F five and Karpov actually played E four here, if you please. 00:35.400 --> 00:38.850 E Free blacks should have an even possession of the Bishop of five. 00:39.750 --> 00:42.350 Let's say Bishop D three and the bishops get exchanged off. 00:42.360 --> 00:44.280 This should be even. 00:44.610 --> 00:52.290 But Karpov plays E four and we have now nine takes E four, which is a bit of a surprise surprise move. 00:52.290 --> 00:53.720 Maybe a prepared novelty. 00:53.730 --> 00:59.070 D takes E four looks more standard and in fact seems to be the best way for black to go here. 00:59.070 --> 01:03.650 For example, Bishop C for Bishop F five, Queen takes E seven check. 01:03.720 --> 01:05.070 Black does have the bishop here. 01:05.070 --> 01:08.730 It is about even when it has a nice queen's pawn as well. 01:08.730 --> 01:12.270 This is really what black should have played, but black plays. 01:12.270 --> 01:21.480 Knight takes E four, which is a novelty move and we have Karpov now playing Bishop STS E seven and 01:21.480 --> 01:25.830 here King takes E seven is basically forced if Queen size E seven. 01:25.830 --> 01:28.190 Can you see what white plays for? 01:28.200 --> 01:29.040 Ten points. 01:31.900 --> 01:34.360 You know, 1965 doesn't matter about this COVID checks. 01:34.360 --> 01:35.470 We're taking the queen. 01:35.770 --> 01:39.860 And if she takes we're playing Queen st Saint-jacques. 01:39.880 --> 01:43.570 So, yes, this is very unpleasant, to say the least. 01:44.210 --> 01:50.380 So so the king takes we have nine, takes e4d takes E for Queen takes e four. 01:50.380 --> 01:52.540 Check Bishop e six. 01:53.560 --> 01:56.470 If King if eight, bishops e four. 01:56.480 --> 01:59.590 And this should be about even perhaps black should have considered that. 01:59.590 --> 02:05.650 But Bishop e six bishops C four and now black starts to go really badly wrong Queen a five check. 02:08.110 --> 02:09.910 So this is an inaccuracy. 02:09.910 --> 02:12.070 Rook eight would have been better. 02:12.070 --> 02:15.010 So, for example, Bishop takes e six, there's CF eight. 02:15.850 --> 02:19.920 And one of the key points here, the Queen's holding the H four square. 02:19.930 --> 02:30.700 So, for example, if White Castle's rook takes e six, this is about even and if Queen H four, then 02:30.700 --> 02:31.930 no problem. 02:31.930 --> 02:34.780 The Queen's are going to come off and that's that's going to be great here. 02:35.260 --> 02:40.570 But in the game of Queen a five check, black is creating a kind of weakness of the last move not controlling 02:40.570 --> 02:43.740 H four and Karpov just plays king F one. 02:43.750 --> 02:46.990 This is a very different scenario and a difficult story indeed. 02:46.990 --> 02:54.130 Statistically, if we look, there's pawns on nine squares, there's a like square bishop and there's 02:54.130 --> 02:56.020 no dark square bishop. 02:56.020 --> 02:59.260 So the dark squares are kind of vulnerable in Black's camp. 02:59.260 --> 03:05.710 Bear that in mind, positionally, because we might want to amplify the dark square weaknesses. 03:05.890 --> 03:09.940 And yes, we haven't got dark square Bishop but the Queen can sometimes act as a dance queen. 03:09.940 --> 03:14.370 Bishop Black plays queen at five if Rook eight. 03:14.410 --> 03:16.720 Here, look at the difference of variations. 03:16.720 --> 03:23.020 Bishop takes e six If King for White has Queen H for hare without penalty because that black queen is 03:23.020 --> 03:25.390 not looking at H four, we're looking at age seven. 03:25.570 --> 03:27.670 So here we can actually play. 03:27.850 --> 03:35.740 In fact, Knight G five is is good even stronger than taking on h7g5 and here for example, nine, 687 03:35.740 --> 03:36.850 check 956 check. 03:36.850 --> 03:38.410 Why it's really doing well here. 03:38.710 --> 03:47.010 This position is very dangerous for black and after h five here it's it's actually a winning advantage. 03:47.020 --> 03:51.580 So Queen five was tried and then we have Queen E free. 03:52.950 --> 03:54.300 And now 97. 03:55.500 --> 03:56.100 Yeah. 03:56.610 --> 03:58.480 I didn't really have much of a choice here. 03:58.500 --> 04:04.050 If Queen takes five, that actually, um, pinned the bishop and black and insert bishop, take C for 04:04.050 --> 04:05.130 check and be winning. 04:05.130 --> 04:05.850 So, Queenie. 04:05.850 --> 04:06.280 Frank. 04:06.720 --> 04:13.650 So keeping the bishop pinned on E 697 rook e 188 So here is a critical moment. 04:13.650 --> 04:19.100 Black statistically has dark square weaknesses, but we don't have a dark square. 04:19.110 --> 04:23.260 Bishop Can we really amplify these weaknesses in Black's camp? 04:23.280 --> 04:27.510 So for 500 points, what is a move that you would play here? 04:29.210 --> 04:30.590 So it's it's a great move. 04:30.590 --> 04:32.570 It's another iconic hop off move. 04:34.610 --> 04:35.190 Okay. 04:35.720 --> 04:36.500 The movie is defined. 04:36.530 --> 04:40.430 It opens up the dark squares for white. 04:40.430 --> 04:45.380 So the dark squares in Black's position are really open up if Bishop takes instead. 04:45.380 --> 04:47.090 F takes H four. 04:47.120 --> 04:49.160 This is plausible to play like this as well. 04:49.160 --> 04:51.920 Actually, White's position is pretty good here as well. 04:52.100 --> 04:53.510 This is another way of playing things. 04:53.510 --> 04:53.660 Why? 04:53.660 --> 04:54.920 It should have an edge here. 04:58.600 --> 05:05.020 You know, as long as one doesn't go crazy with something like quinine, free check and taking and taking 05:05.050 --> 05:07.960 too many liberties, this this position is okay. 05:08.050 --> 05:12.070 But if if Queen takes a seven, then queen bee five shouting, the queen could get trapped. 05:12.070 --> 05:13.060 That would be silly. 05:13.060 --> 05:18.790 But yeah, white can play it much more sensibly with H four here and still have a commanding position 05:18.790 --> 05:19.870 of free. 05:19.870 --> 05:22.180 But anyway, D five is really interesting move. 05:22.180 --> 05:28.300 We have C takes D five, bishop B five and now a six. 05:29.860 --> 05:32.110 So this is a very interesting position. 05:32.110 --> 05:36.970 This weakens even more statistically, it weakens even more dark squares in Black's camp. 05:38.560 --> 05:45.790 Queen C two is an interesting try 94 for taking on B two Queen G five check king for nine takes. 05:45.790 --> 05:51.460 E six is winning material and Black doesn't have enough compensation here. 05:51.460 --> 05:57.760 It seems as though White should be better here with the bishop against lots of pawns, but white should 05:57.760 --> 05:58.540 be better. 05:59.110 --> 06:01.300 So a six was played though. 06:01.300 --> 06:04.330 We have queen a free check, King D eight. 06:04.480 --> 06:14.140 If king of six, we see an amazing situation tactically crowning White's positional dance square strategy 06:14.140 --> 06:15.870 for the positional pawn sacrifice. 06:15.880 --> 06:16.750 Can you see what that is? 06:16.750 --> 06:17.980 What is why at play here? 06:19.890 --> 06:22.250 Might simply amplifies the dark squares even more. 06:22.260 --> 06:25.830 Sometimes trading off a light square bishop for a night will do that. 06:25.830 --> 06:28.140 So that takes away e five control. 06:28.140 --> 06:31.470 And this is fatal for black after Queen C free check. 06:32.130 --> 06:34.260 Black is cool here. 06:34.950 --> 06:37.740 Would have to give up a rook and it's just a total disaster. 06:37.740 --> 06:40.320 More material or mater will follow. 06:41.490 --> 06:44.910 So King D eight we have Queen A five check King E seven. 06:45.780 --> 06:49.040 If B six won't can simply just take on a six hair. 06:49.050 --> 06:52.770 This position D four is strong in hair queen. 06:52.850 --> 06:54.180 Fall That's a strong position for white. 06:54.180 --> 06:57.660 So King is seven queen before checking off six 07:00.090 --> 07:00.870 so. 07:02.070 --> 07:08.580 Here if King 894 is good here, any move other than Queen F six if well, if going to the fifth rank, 07:08.580 --> 07:12.450 there's no takes E six check and we're going to be winning the queen. 07:12.450 --> 07:14.100 Unless the queen wants to give herself up. 07:14.100 --> 07:15.750 We're just winning the queen like that. 07:16.110 --> 07:18.090 So, yeah, very dangerous scenarios. 07:18.600 --> 07:24.390 And if Queen F six her, this position is comfortable for whites, for example, here taking out B seven. 07:24.390 --> 07:26.520 Black's structure is damaged. 07:26.850 --> 07:31.470 So King F thinks we have Queen D for King E seven. 07:31.470 --> 07:34.140 So the queen has taken some time to get to D four. 07:34.140 --> 07:35.910 So that's a really interesting situation. 07:35.910 --> 07:39.150 Those checks just to get to D four if we look. 07:39.150 --> 07:43.200 So this is a move 22 with Bishop D free. 07:43.200 --> 07:45.000 So the Queen is on D four. 07:45.000 --> 07:53.130 If we were going to see where we came from, we came from a position here where the Queen was on e free. 07:54.740 --> 07:55.070 Yeah. 07:55.070 --> 08:01.220 So these checks ending up just putting the queen on D four, but the queen is nice and central. 08:01.220 --> 08:03.680 So Bishop D three we have Queen H five. 08:04.100 --> 08:08.900 If Queen F thinks her queen be full check and disposition Queen takes B seven. 08:09.140 --> 08:12.450 There is a little trick here for black, which needs to be factored in. 08:12.470 --> 08:13.610 Funny enough. 08:13.820 --> 08:14.900 Can you see what that is for? 08:14.900 --> 08:15.470 Ten points? 08:15.470 --> 08:17.330 What's Black's little tactical trick? 08:21.480 --> 08:21.700 Yeah. 08:21.720 --> 08:26.070 Queen sakes are free so that if G tanks gets mated, Bishop is free. 08:26.100 --> 08:26.520 Check. 08:26.520 --> 08:29.060 Rook takes E one and one gets mated. 08:29.070 --> 08:30.480 However, why? 08:30.480 --> 08:31.890 It doesn't play ball. 08:31.890 --> 08:34.770 There won't place queen a check. 08:34.770 --> 08:37.800 And then here Queen takes eight and this is better for white. 08:38.010 --> 08:41.220 So anyway, Queen H five was played. 08:41.220 --> 08:44.880 Queen of six was objectively maybe slightly better than Queen H five. 08:44.880 --> 08:46.890 This is very bad for the Queen's position. 08:46.890 --> 08:51.570 Now we have H four which sets up support for G five. 08:51.570 --> 08:57.870 So setting up support on the dark squares which are weakened around Black's position generally we have 08:57.870 --> 09:01.980 King d89, G five. 09:04.490 --> 09:05.840 Look, I ain't. 09:07.400 --> 09:13.070 So here we have Bishop E2 harassing the Queen Queen aged six and now Bishop offering. 09:15.740 --> 09:19.280 So Rook e seven and now Queen Bee four. 09:20.240 --> 09:22.700 So this stops the king for moving kings. 09:22.820 --> 09:23.540 Holding that rook. 09:23.540 --> 09:27.730 We have knights f six And here Queen RD six checks. 09:27.740 --> 09:31.280 So bouncing around blacks position, Queen F four. 09:31.280 --> 09:38.330 So this sets up lots of ideas like night takes and Queen tanks or Queen tanks and Black's only move, 09:38.360 --> 09:38.720 basically. 09:38.720 --> 09:39.510 Knight G eight. 09:39.530 --> 09:45.290 So just to show B five, Knight takes E six check and taking on H six or Queen G seven. 09:45.650 --> 09:48.920 There's actually here another tactical idea can you see for ten points. 09:50.790 --> 09:51.180 Yeah. 09:51.690 --> 09:54.900 Rook takes six would be crushing for the family fork. 09:54.960 --> 09:55.500 So. 09:55.500 --> 09:56.210 Okay. 09:56.250 --> 10:00.910 We have had one of the only moves in G eight stay on the board for a bit longer. 10:00.930 --> 10:03.780 But now Karpov really amplifies the pressure. 10:03.780 --> 10:04.290 Bishop G. 10:04.290 --> 10:06.360 For we have King C eight. 10:06.450 --> 10:10.320 If Bishop takes G for Queen Bey is checkmate. 10:10.320 --> 10:16.410 So King C eight, Bishop takes e6f tanks and now Rook C one checks. 10:16.410 --> 10:22.610 This forcibly wins material so one can either play queen takes a fight or like in the game, Knight 10:22.620 --> 10:25.170 takes e six check and just win the exchange. 10:25.170 --> 10:31.290 So after this it's basically a one possession and play continues. 10:31.290 --> 10:39.090 Rook H free 90 7h5 can do seven comp sets up the form pawn or in the form pawn is good in end games 10:39.120 --> 10:43.010 check here and now we have King E six. 10:43.020 --> 10:46.650 Otherwise there's an almighty pin with rook f seven of King G five. 10:47.040 --> 11:01.290 So we have King six rookie one check King six Rook have six King c7g4 96 rook e8d4. 11:01.290 --> 11:03.510 And the position's pretty hopeless here. 11:03.630 --> 11:05.700 Black actually resigned. 11:05.700 --> 11:10.500 There is an easy winning method for white against this seemingly quite scary pawn. 11:10.500 --> 11:12.870 We've got to be careful about past pawns here. 11:12.870 --> 11:15.780 One of the key moves would be Rook G eight. 11:15.780 --> 11:18.810 So our form pawn supports rook g seven. 11:19.080 --> 11:26.940 So say D free we can play rook g seven and not fair d2 at all because anytime D2 happens, there's a 11:26.940 --> 11:28.380 weakness of the last move. 11:28.380 --> 11:30.150 The pawn is actually allowed. 11:30.150 --> 11:36.810 King E two We just take on D seven first check, then King E two, and that's it for black. 11:37.350 --> 11:38.340 Another way of playing it. 11:38.340 --> 11:46.560 We can first head the king towards D one, but still a key mechanism here is Rook G eight. 11:46.560 --> 11:50.790 That's just a beautiful mechanism to simplify, which is worth knowing with the form pawn. 11:50.790 --> 11:53.580 In fact, in my view, formulas are pretty useful. 11:53.610 --> 11:56.910 Endgames, those form pawns, those hooks are very, very useful. 11:56.910 --> 11:58.410 And Black's had it there. 11:58.410 --> 12:00.420 So yes, the end of the game after default. 12:00.450 --> 12:05.430 So one of the key aspects of this game is the notion of the positional sacrifice. 12:05.430 --> 12:10.170 It's almost as if we can look statistically at Black's position at the moment. 12:10.170 --> 12:16.530 The positional pawn sacrifice was played and see around and say, Black hasn't got the dart square bishop, 12:16.530 --> 12:18.990 so it's something we can amplify What they haven't got. 12:19.020 --> 12:23.250 What they have got statistically is kind of relative weaknesses for dark squares. 12:23.250 --> 12:29.970 When the adjacent light squares, they're not supporting the dark squares and the positional pawn sacrifice 12:29.970 --> 12:33.090 with the king and center is really instructive on my view. 12:33.090 --> 12:36.810 So a very iconic move, this positional pawn sacrifice playing for the position. 12:36.810 --> 12:40.680 It shows the great difficulties black head in wriggling out here. 12:40.680 --> 12:46.290 So yeah, a really fantastic game from Karpov kind of strategy and tactics blended together. 12:46.290 --> 12:49.320 I hope you enjoyed this as much as me and so much.
