WEBVTT 00:00.900 --> 00:01.720 Hi there. 00:01.800 --> 00:09.450 In this lecture, we see Stefano Satie against Anatoly Karpov in 1977, Palmer's tournament round 13. 00:09.540 --> 00:14.520 We have an English opening C4 and Karpov reacts with the symmetrical variation. 00:14.550 --> 00:20.190 See 59239569c free but now breaks the symmetry with D five. 00:21.180 --> 00:23.570 C takes d59 times D five. 00:23.580 --> 00:25.560 We have g fre g six. 00:25.560 --> 00:26.400 Bishop G two. 00:26.400 --> 00:27.510 Bishop g seven. 00:27.900 --> 00:33.830 An alkene A four, c six and here g five is played. 00:33.840 --> 00:37.830 This is quite the adventure in the opening, putting pressure on D five immediately. 00:38.850 --> 00:40.830 So why is one doing this? 00:40.830 --> 00:44.610 Well, one of the ideas is to gain the tempo to look at C five. 00:45.520 --> 00:50.460 It's a very interesting situation if White Castle's 97 is possible. 00:50.670 --> 00:59.820 And in fact here, let's say Knight G five, Bishop D seven is possible with a view of actually just 00:59.820 --> 01:00.810 castling. 01:00.810 --> 01:08.520 Well, to safeguard F seven and offer C five, here is one interesting positional sacrifice of a pawn. 01:09.210 --> 01:12.660 So black gets quite a bit of development here and pressure. 01:12.660 --> 01:18.390 So for example, here the queen goes back b5ae5. 01:18.390 --> 01:21.390 Black has quite a formidable grip on the possession. 01:22.200 --> 01:28.530 And for example, if wrote B 194 there is quite significant pressure building up on the white position 01:28.530 --> 01:31.500 and the Queen seems awkward in the game. 01:31.500 --> 01:33.570 9g5 was played. 01:33.720 --> 01:39.570 We have E, six, g, e four, so C five is on the fire. 01:39.570 --> 01:43.140 We have Karpov playing Knight B six after Queen B five. 01:43.410 --> 01:46.320 This is already a very interesting situation. 01:46.320 --> 01:49.140 Karpov plays C five. 01:50.580 --> 01:51.840 So here. 01:53.450 --> 01:56.060 If black had castles instead. 01:56.090 --> 01:58.730 This is also kind of interesting. 01:58.730 --> 02:02.990 For 94, there is compensation here in this position. 02:03.260 --> 02:13.700 For example, Rooke might just to repair soon another forcing move B six without losing the rook and 02:13.700 --> 02:15.950 black ends up with a lot of pressure here. 02:15.950 --> 02:20.750 There's good compensation and Black's getting some material back as well. 02:21.170 --> 02:30.290 This would be a very interesting position indeed for Black and if Queen St see 594 there's compensation 02:30.290 --> 02:40.270 here to be had after five 9692 and here we can see actually after Bishop de fall, this is quite painful. 02:40.280 --> 02:43.880 Queen 66 winning material. 02:44.600 --> 02:48.050 So so C4 though is an interesting move. 02:48.290 --> 02:53.600 We have 94 being played. 02:53.600 --> 03:02.960 If Queen C five Black can play a tempo gain at Bishop of eight if needed, that seems to safeguard things 03:02.960 --> 03:03.920 fairly well. 03:04.160 --> 03:05.990 So a four. 03:06.200 --> 03:11.720 And now guess what Karpov plays, which you might find really fascinating. 03:12.260 --> 03:13.760 So Black's play. 03:15.720 --> 03:18.960 OC cup of this councils. 03:18.960 --> 03:22.170 He's making this into a possession or pawn sacrifice. 03:23.250 --> 03:24.180 So nine times. 03:24.210 --> 03:25.050 Be six eight. 03:25.260 --> 03:28.480 And also structurally of course, accepting some damage. 03:28.500 --> 03:36.840 So Queen C for E five, there is a large amount of compensation here and tempo gainers as well. 03:36.840 --> 03:39.990 Concretely to play with, we have Quincy two. 03:40.020 --> 03:49.110 If one cancels Bishop Essex and let's say Quincy 294 why it's been pushed on to the first rank and in 03:49.110 --> 03:50.430 fact bishop be free. 03:50.430 --> 03:53.760 Ouch making use of the pins pawn. 03:53.760 --> 03:55.740 And here you know we're winning with Terrell. 03:55.740 --> 03:57.210 But what does white do? 03:57.240 --> 04:02.160 Queen E one as bishop takes a two hair which is nice fresh thing. 04:02.160 --> 04:03.720 Things like knight be free. 04:03.900 --> 04:05.970 So Queen D one that's a queen D one. 04:05.970 --> 04:14.220 Queen C seven is very accurate with the idea of bishop be free and that's hitting the rook. 04:14.220 --> 04:16.880 So we'd be actually winning material by force here. 04:16.890 --> 04:18.420 It's just great for black. 04:18.780 --> 04:20.850 So that shows some of the dangers. 04:21.700 --> 04:30.700 So we have Queen C 294, Queen B one and our f59, C three, E four. 04:31.420 --> 04:34.360 You might think shouldn't white make priority. 04:34.390 --> 04:37.420 Hence Castle de France plate. 04:37.450 --> 04:39.160 So you might think that's strange. 04:39.160 --> 04:39.790 But if. 04:39.790 --> 04:41.110 Cos then guess what? 04:41.110 --> 04:43.840 Black plays here, which ramps up the pressure. 04:47.020 --> 04:50.410 And there is bb5 to try and nudge the knight and win ito. 04:50.620 --> 04:53.290 If e free Knight a free check. 04:53.290 --> 04:56.170 This is very interesting to get a pawn on on for free. 04:56.200 --> 04:58.690 It's very dangerous for wait's king safety. 04:58.690 --> 05:06.940 And for example, here with that loose knight we can play F4 and actually target soon will either make 05:06.940 --> 05:17.230 the queen or if Queen de free, we can play Queen D7 seven looking at B5 and also to try and mate with 05:17.230 --> 05:17.860 this. 05:18.400 --> 05:24.610 And the thing is, if E takes sure that answers Queen H free with Queen sex free. 05:24.760 --> 05:31.750 But we have rook F5 hitting B5 And how does Black actually defends the B5 Knight here? 05:32.350 --> 05:36.940 This is embarrassing if check where's Knight going? 05:37.300 --> 05:42.010 If A4 we just started off using the pins pawn on the file. 05:42.130 --> 05:43.750 Fascinating stuff. 05:44.050 --> 05:47.750 So yes, B5 overall just seemed really interesting. 05:47.770 --> 06:01.840 If rookie one b4 Knight rd one we have b free and this looks kind of positioning crushing if A3 let's 06:01.840 --> 06:06.910 say a free because white doesn't want to allow rook tanks in 92. 06:07.930 --> 06:10.300 Yeah, this is really horrendous stuff. 06:10.660 --> 06:14.350 But yeah, rook tanks and 92 for king, Queen and rook. 06:14.530 --> 06:22.030 But let's say a free this looks terrible for white after 92, and then we can do all sorts of things. 06:22.030 --> 06:23.620 We don't even have to take the rook. 06:23.620 --> 06:30.400 We can just torture white here and just ramp up the pressure, and it's just brilliant. 06:31.120 --> 06:32.890 So we could even just go for the attack. 06:32.890 --> 06:34.690 We don't even need to take on a one. 06:35.980 --> 06:37.900 And so we need to add Bishop C4 here. 06:37.900 --> 06:44.890 For example, we can win lots of material elsewhere and just keep everything stranded for white. 06:45.400 --> 06:47.770 So anyway, so d free. 06:47.770 --> 06:51.460 That helps explain maybe why the king was left in the center. 06:51.460 --> 06:59.830 We have B5 now Bishop e free if one cancels B4 again and then we're going to take on E2 with Shaq. 07:00.220 --> 07:03.640 And this is just great for Black after E takes DD free. 07:03.640 --> 07:15.620 So Bishop e free try b4 91 rookie eight D takes e for F, take C4 and now Bishop takes D4 in stride. 07:15.640 --> 07:18.580 If White Castles Knight takes E to check. 07:18.850 --> 07:22.300 And here Queen de five reinforcing E four for a moment. 07:22.450 --> 07:26.050 And our Bishop g for this is just a very strong position for Bishop free. 07:26.200 --> 07:35.410 And here, for example, we're dominating the position when it's really kind of looking how's back held 07:35.410 --> 07:39.900 in a terrible binds if Knight C free. 07:39.910 --> 07:42.790 Yeah we can even play like this and we don't even have to play bishop. 07:42.820 --> 07:43.870 Take C free. 07:43.870 --> 07:46.570 We can just continue with Rook, take C free. 07:46.750 --> 07:51.910 And then we've just got a massive position here with a great pass pawn there guided by the bishop. 07:52.570 --> 08:02.980 So Bishop takes the fall was tried Queen takes D for a free if White Castle's here Bishop G for rookie 08:02.980 --> 08:08.800 one And actually we have Bishop H six which creates sometimes the possibility of Bishop D2 being useful. 08:10.150 --> 08:12.100 Yeah, this is quite amazing. 08:12.100 --> 08:19.690 If a free queen D2 is also useful 90 free, we can take on EA free and this position is just great. 08:20.740 --> 08:22.510 But what else? 08:22.780 --> 08:23.830 If h free? 08:23.830 --> 08:28.960 We can use Bishop D2 here and in this position Bishop takes e2. 08:30.820 --> 08:31.080 Yeah. 08:31.300 --> 08:39.970 If e free queen d2 this position AC eight and we've got a dominant position after Bishop E2 and then 08:39.970 --> 08:40.450 be free. 08:40.480 --> 08:41.560 What is white doing here? 08:41.560 --> 08:42.820 We're just winning material. 08:43.240 --> 08:45.850 So okay, a free was tried. 08:45.940 --> 08:47.500 The king still in the center. 08:47.500 --> 08:48.310 Bishop G. 08:48.310 --> 08:50.680 For Quincy two. 08:50.710 --> 08:54.160 If one cancels here, we're just going to take on E2. 08:54.190 --> 08:56.530 Thanks very much, Queen DD two. 08:57.640 --> 09:01.330 And this is pretty embarrassing. 09:01.330 --> 09:06.940 Let's say check on me, Queen nine to check King on 93. 09:06.940 --> 09:08.830 We can just play Bishop DD free here. 09:09.310 --> 09:15.250 And we're looking to win sometimes B two, so this is just great for us. 09:15.490 --> 09:17.050 So Queen C two. 09:18.640 --> 09:20.650 Now this is a star move of the game. 09:20.800 --> 09:23.440 What would you play in this position for 100 points? 09:24.520 --> 09:27.220 This is a really cool looking move. 09:29.910 --> 09:30.570 Okay. 09:33.510 --> 09:33.780 Yeah. 09:33.810 --> 09:36.630 KING The sense that we can play queenly, free one a tempo gainer. 09:39.160 --> 09:44.030 So yes, the pain of being a pawn up, but pieces are so bad. 09:44.050 --> 09:45.260 King and center. 09:46.540 --> 09:49.330 So Wayne Wayne's fed up with being pushed around. 09:49.330 --> 09:50.380 Why it has to react. 09:50.410 --> 09:51.820 He takes DD free. 09:52.330 --> 09:53.980 He takes the free check. 09:54.880 --> 09:59.530 KING And now the Kings checked here and brought up the boards. 09:59.560 --> 10:04.120 ROOK The ancient kings see four rook take to check. 10:05.020 --> 10:06.580 KING Thanks b4. 10:07.180 --> 10:12.820 So why is two pawns up but off the rook? 10:12.850 --> 10:15.040 KD two There's big problems. 10:15.040 --> 10:20.320 The knight is pressurized here so that shoot it with their free. 10:20.590 --> 10:27.180 The thing is, if I see free weakness of the last move, we're going to take on B two and here win material 10:27.190 --> 10:28.810 or checkmate soon. 10:29.150 --> 10:31.380 For example, like this, we're going to checkmate soon. 10:31.390 --> 10:32.320 Cute. 10:32.530 --> 10:34.720 So C three is totally out of the question. 10:34.720 --> 10:36.460 So how else to defend? 10:38.700 --> 10:40.470 The night on day one. 10:42.450 --> 10:44.130 And, you know, this is quite vicious. 10:44.130 --> 10:47.280 Rock takes pizza if night moves, among other things. 10:47.400 --> 10:48.950 So everyone's tried. 10:48.960 --> 10:53.430 We have Bishop, I think Jack King, a five. 10:55.300 --> 10:58.390 And then Bishop D seven and this ends the game Y actually resigned here. 10:58.600 --> 10:59.980 Two pawns up. 11:00.820 --> 11:01.450 Yeah. 11:01.450 --> 11:08.710 If F for let's say F for rook D six has the cute idea of rook six Checkmate. 11:08.740 --> 11:10.310 The bishop's holding B four. 11:10.330 --> 11:14.350 If bishop takes B seven to against Rook six. 11:14.350 --> 11:15.940 We should just play rugby ain't. 11:16.360 --> 11:19.660 And if the bishop moves, then B five check. 11:19.660 --> 11:21.490 And we've got a low make pattern. 11:21.940 --> 11:26.680 So yes, Q ends the game if, let's say H four, we can simply pay Bishop C five. 11:26.680 --> 11:29.890 If this is not addressed, we're going to play Rook eight mating. 11:31.480 --> 11:35.680 And yeah, what is what is happening here? 11:35.680 --> 11:41.110 Yeah, the king is just getting mated in various ways, basically. 11:42.880 --> 11:44.020 So yes. 11:45.500 --> 11:48.140 It's pretty vicious if Rook see one to stop. 11:48.140 --> 11:52.460 Bishop c5 Rook dd six again for Rook six. 11:53.030 --> 11:54.320 If Rooks five. 11:54.890 --> 11:57.050 Rook eight is cute. 11:57.770 --> 11:59.330 So here Rook takes the eight. 11:59.330 --> 12:00.950 We can now play. 12:00.950 --> 12:01.550 Rook six. 12:01.550 --> 12:02.240 Checkmate. 12:02.510 --> 12:04.820 So, yes, a very, very cute game. 12:04.820 --> 12:09.470 Positional pawn sacrifice in the English opening symmetrical variation. 12:09.470 --> 12:15.650 So it seems as though there was a tempting downside out of the opening that black C pawn this liberating 12:15.650 --> 12:16.040 D5. 12:16.040 --> 12:18.560 Surely it had a cost, maybe ten. 12:18.650 --> 12:22.700 I was thinking that this C five pawn would be a useful target. 12:22.820 --> 12:31.670 But yeah, Karpov is not afraid to play dynamically here and just sacrifice that pawn and pawn structure 12:31.670 --> 12:33.810 in spectacular style here. 12:33.830 --> 12:41.390 So this is really quite vicious positional pawn sacrifice, creating a huge, impressive initiative 12:41.390 --> 12:44.270 and huge tactics to back that up. 12:44.450 --> 12:46.910 Tempo, gainers, sacrifices, the works. 12:46.910 --> 12:52.970 So it shows the tactical side of Karpov, but making use of a key positional sacrifice to really get 12:52.970 --> 12:57.530 a massive initiative going where Karpov is calling the shots, making the threats. 12:57.530 --> 13:04.880 And Black's white White, rather, is just having to defend all the time throughout this game. 13:04.880 --> 13:06.710 So a really amazing game of Karpov. 13:06.710 --> 13:10.250 I hope you enjoyed this game as much as me as you much.
