WEBVTT 00:01.020 --> 00:01.820 Hi there. 00:01.830 --> 00:05.460 In this lecture, we see Anatoly Karpov playing against the Massimo Hort. 00:05.460 --> 00:08.370 In 1971, Moscow two went round 11. 00:08.370 --> 00:19.980 We see E four from Karpov, a Sicilian defense from Hort Knight every D six d4 c text e4 96349569c free 00:19.980 --> 00:20.940 and now e six. 00:20.940 --> 00:26.730 The old shaven engine was popular but now has been overtaken generally with the night off. 00:26.730 --> 00:28.950 Move order a sex. 00:28.950 --> 00:38.580 One of the reasons is that black controls g for hair making the carers attack unplayable, but after 00:38.580 --> 00:41.040 e six the cars move is pretty strong. 00:41.040 --> 00:47.460 G for the Bishop has been stopped from controlling G four and is actually a rather good move. 00:47.460 --> 00:52.230 The camera has a tank we see 90 6g5 So why it's gaining space here? 00:52.500 --> 00:55.230 97 and now F four. 00:55.230 --> 01:01.980 Now some sources actually indicate Bishop E free was the move this does actually seem to make more technical 01:01.980 --> 01:09.420 sense because let's say h six we can just take on h six and this is just a good position. 01:09.420 --> 01:17.430 But if this is the move order with F four, the king still in the center and actually here, if this 01:17.430 --> 01:29.190 is the move order then I6 was played by H six does seem interesting here because h fours needed if g 01:29.220 --> 01:34.920 takes h six there's Queen H four check and there's no mechanism for Bishop F2. 01:35.160 --> 01:40.110 So this position after D five is actually in Black's favor. 01:40.650 --> 01:45.120 This is actually getting a little bit scary for white with the king in the center. 01:46.410 --> 01:50.070 So if that's the case, an H four would be needed here. 01:50.070 --> 01:53.730 H takes F takes white would lose positional control of e five. 01:53.730 --> 01:54.870 It makes quite a difference. 01:54.870 --> 01:58.350 The move order here and this position is going to be about even. 01:58.500 --> 02:05.970 But anyway, let's go with this a six So this move to Bishop e three So we have this position anyway 02:05.970 --> 02:06.480 for sure. 02:06.480 --> 02:12.890 Bishop e seven Rook G one Knight takes the four queen 34e5. 02:12.900 --> 02:19.320 Now this does weaken the D five square a bit, but Black is hoping to get a strong knight on E five. 02:19.320 --> 02:22.020 So he takes a four, Bishop takes a four. 02:22.020 --> 02:30.570 And now 95 we have an immediate threat of going free, which is currently check kind of a firmly fork. 02:30.570 --> 02:33.240 And even if White Castle still be the queen and rook. 02:33.240 --> 02:43.500 So White covers F three and we have Bishop E six and now in this position, 95 and Black is annoyed 02:43.500 --> 02:46.680 by that knight somewhat and actually stamps it off. 02:46.680 --> 02:49.020 There are two ways to take on D five here. 02:49.020 --> 02:52.860 E takes D five is chosen by Karpov, which is interesting. 02:52.860 --> 02:57.480 Queen takes D five does seem to be as good in other respects. 02:57.810 --> 03:03.990 So for example Queen B six we can just castle queenside and it looks like if Black Castles kingside, 03:03.990 --> 03:05.880 we've got a ready made attack here. 03:05.880 --> 03:10.470 This seems to be a sensible way to proceed with a small advantage. 03:10.830 --> 03:15.150 But e takes 35 was played and this is also good in other ways. 03:15.150 --> 03:20.970 So 96 we have Bishop E three, h686 Here is interesting. 03:20.970 --> 03:26.790 So G tanks Black is still trying to exploit the king in the center in the main line of the game here. 03:27.870 --> 03:33.600 If White played h four instead h takes h takes 95. 03:33.600 --> 03:37.350 This is also playable without too much hassle. 03:37.470 --> 03:43.350 But we have G tanks and Bishop H four check King d1g takes 86. 03:43.350 --> 03:49.710 So the way karpov's playing it, he is actually giving it seems a little bit of play to black, but 03:49.710 --> 03:53.430 he is creating a pos pawn in this particular game example. 03:53.430 --> 03:58.500 Now that looks as though that possible is never going to make it at the moment, but as things clear 03:58.500 --> 04:00.300 away it becomes stronger and stronger. 04:00.300 --> 04:02.060 This h two pawn. 04:02.070 --> 04:06.300 So keep on keep a watch on that if a four instead. 04:06.300 --> 04:14.100 This is actually a way to keep more positional control without grabbing h six and it's frantically you 04:14.100 --> 04:20.970 might find in some comp of games as quite often the ones where black has no counterplay at all. 04:20.970 --> 04:24.870 And Karpov is like a python strangling the opponents out of counterplay. 04:25.500 --> 04:29.190 Those are more celebrated quite often sadistic chess players. 04:29.190 --> 04:32.490 But this one, yeah, there's a little bit of play, it seems. 04:32.490 --> 04:39.090 So this this way there wouldn't have been so much play, it seems, with a four. 04:39.120 --> 04:40.170 Let me just clarify that. 04:40.170 --> 04:46.950 So this position, if white doesn't grab on H six and just play, for example, Queen D for her, Bishop 04:46.950 --> 04:49.110 G for Jack White has the bishop pair. 04:49.110 --> 04:50.610 And this is a checkmate, by the way. 04:50.610 --> 04:52.140 This is a checkmate disaster. 04:52.140 --> 04:54.780 So this is quite an amusing variation. 04:54.900 --> 04:56.520 Let me be more sensible here. 04:57.330 --> 04:59.040 So Queen E seven. 05:00.140 --> 05:05.450 Rate this position with queenly four is still it's still better for white. 05:05.480 --> 05:09.170 White can actually manage the pressure with a move like rook free. 05:09.170 --> 05:15.020 So there is a great way of keeping control of the position or the bishop hair and it seems A4 is the 05:15.020 --> 05:15.860 way to go. 05:16.370 --> 05:18.980 So that is a fascinating move to use that photo rank. 05:19.130 --> 05:21.890 Yeah, there's an interesting feature about this position already. 05:21.890 --> 05:27.320 That third rank is kind of useful, but also the full frank is nearly clear in the main line of the 05:27.320 --> 05:27.500 game. 05:27.500 --> 05:33.530 You can see the third and the fourth are kind of useful resourcefully for rooks to swing if they need 05:33.530 --> 05:34.120 to. 05:34.130 --> 05:34.910 It's very interesting. 05:34.910 --> 05:39.500 Furthermore, for Frank Claire Bishop her so this is the main line of the game. 05:39.500 --> 05:42.180 Bishop f6 We have C three So blunting the Bishop. 05:42.180 --> 05:48.440 It seemed logical we have Bishop E five and now with Bishop E five, black is Francis thing potentially 05:48.440 --> 05:57.170 Queen H four and Rook G4 actually prevents Queen H four and also introduces options are rook before 05:57.170 --> 06:03.980 so it's attacking and defensive rook g for we have Queen f6 if Bishop takes H two. 06:04.490 --> 06:05.180 Yeah. 06:05.810 --> 06:07.440 Getting rid of that passport. 06:07.880 --> 06:10.670 What will I have here after King C two? 06:10.670 --> 06:16.280 It does seem slightly better for White in other respects, even though we've lost that possible rookie 06:16.280 --> 06:26.300 one for example here rook before and where there's black actually castle the in the center if black 06:26.300 --> 06:32.480 castles queenside let's say Queen E free and then there's bishop takes a sixth of the king wants to 06:32.480 --> 06:37.130 move off to to avoid queen a seven invasion. 06:37.130 --> 06:43.190 But it's a disaster here where Bishop takes a six this looks like yeah, Black's king is in big trouble. 06:43.190 --> 06:48.410 So although Black gets rid of White's past pawn, the trade off here is king safety. 06:49.040 --> 06:55.940 If we look at 22 instead of taking the pawn, what about Queen B sex as an example? 06:57.080 --> 06:59.870 King C two and black horse was here. 07:00.020 --> 07:02.480 Rook before Queen 85. 07:02.480 --> 07:06.530 We've actually got Bishop E free here with a strong threat of bishop. 07:06.560 --> 07:07.490 He's six. 07:07.490 --> 07:12.830 So, you know, for example, here, this is great for white to win the queen like that when material 07:13.940 --> 07:14.750 so. 07:16.660 --> 07:17.980 Okay, so. 07:18.880 --> 07:25.510 What does have a resource reductase e to but we can basically win material with Bishop takes a five 07:25.510 --> 07:26.590 at minimum. 07:26.590 --> 07:30.790 What we can do is just take an analysis and we're material up here. 07:31.060 --> 07:35.530 So anyway, Queen F six was tried, we have H four. 07:35.560 --> 07:38.140 So that passport is taking a step forward. 07:38.560 --> 07:40.210 We have Queen five. 07:40.210 --> 07:45.010 If nine takes H for Bishop G five is cute to win material. 07:45.250 --> 07:51.340 So Queen at five we have Rook before, so it's kind of majestic how this four frames used. 07:51.670 --> 07:57.640 The third rank is has got a block pawn but this for Frank is kind of cute and also functional because 07:57.640 --> 08:02.860 there's Bishop G for F Black Castled Bishop f six is actually an inaccuracy. 08:02.860 --> 08:06.580 It seems 97 might be the better way to go. 08:06.580 --> 08:11.860 And then here B five should be only a small edge for white if black cancels. 08:11.860 --> 08:14.400 Bishop G four So okay. 08:14.470 --> 08:16.780 Bishop F six we have h five. 08:16.780 --> 08:20.620 So that pawn is making steady progress down the board. 08:20.620 --> 08:24.970 And now, yeah, this is interesting range thing. 08:25.090 --> 08:27.790 So comp doesn't take on B seven. 08:27.790 --> 08:32.680 He plays rook at four and we have Queen E five. 08:32.680 --> 08:33.640 So now. 08:35.110 --> 08:37.120 Because why is blocked eight six Black is frightening. 08:37.120 --> 08:44.470 Rook takes h six Currently we have rook three maybe a little bit more accurate is actually rook f2. 08:45.430 --> 08:49.750 So rook F2 also protects the bishop and some other options. 08:49.750 --> 08:58.810 For example, if black castles queenside king c2 if rook takes h six Air Queen tanks Bishop H four We 08:58.810 --> 09:02.170 have Queen F4 offering the exchange back. 09:02.260 --> 09:04.330 And this might be interesting for white. 09:04.330 --> 09:05.920 This position is interesting. 09:05.920 --> 09:13.660 We have a past pawn and saint after Bishop G for check, we can play rookie one to reinforce any tricks. 09:13.660 --> 09:17.290 Hence the e free the free square with the E free squire Queen G five. 09:17.290 --> 09:20.530 This position ends up being better for white. 09:20.590 --> 09:25.770 The king can find safety potentially if it is rust. 09:25.780 --> 09:31.840 So for example here this is going to be a position where White's making some progress with the past 09:31.840 --> 09:34.600 pawn Bishop seems a bit better than a knight. 09:34.600 --> 09:41.670 Black has structural defects overall white slightly better here, but our rook, our free was played 09:41.680 --> 09:43.150 and we have Knight 65. 09:43.150 --> 09:44.140 This is a mistake. 09:44.140 --> 09:48.610 It seems black can fully equalize with castling queenside here. 09:48.610 --> 09:56.740 So Bishop f4 this position for example and let's say black gobbles on the five rook d free so black 09:56.740 --> 10:06.250 would be a pawn up and white can get the pawn back in in this example and here can bail out for a perpetual 10:06.250 --> 10:07.930 check at minimum. 10:08.560 --> 10:12.880 So at least white can force a perpetual check in that example variation. 10:12.880 --> 10:16.690 But yet it seems as though castling was the way to go here. 10:18.160 --> 10:19.570 So that's interesting. 10:20.890 --> 10:22.840 But Knight takes DD five. 10:22.840 --> 10:25.930 We have rook D free and our rook takes H six. 10:25.930 --> 10:27.520 So simplification here. 10:27.940 --> 10:29.800 If the knight had just gone back. 10:29.800 --> 10:32.200 Bishop four and the Queen a five. 10:32.200 --> 10:33.910 King to this position. 10:33.910 --> 10:36.370 Bishop takes DD six White has a big advantage. 10:36.370 --> 10:39.940 So Rook takes H six and we have rook takes D five. 10:39.940 --> 10:42.520 So not queen size h six. 10:42.520 --> 10:46.240 So this would lose control of the position trying to win material here. 10:46.240 --> 10:47.980 It seems because of a knight at four. 10:48.010 --> 10:54.760 What would white do with this fork rook DD two The thing is King is seven and White's rook is still 10:54.760 --> 10:56.470 asleep on a one here. 10:56.860 --> 10:58.900 And this is a very difficult position. 10:59.080 --> 11:03.340 If Queen H seven Rook eight Queen goes back. 11:03.340 --> 11:09.280 Rook G eight We can't black can't take the pawn, but black on black is kind of menacing White's king 11:09.280 --> 11:12.700 here Black's getting a huge advantage so it's good. 11:12.700 --> 11:18.940 Karpov kept control relatively speaking with Rook takes D five forget Queen takes H six, even though 11:19.240 --> 11:21.100 it's opposite kind of bishops. 11:21.100 --> 11:27.970 And maybe one of the things about this game is its compas philosophy about even the microscopic advantage. 11:27.970 --> 11:32.050 If it's non controversial, he doesn't mind playing with microscopic advantage. 11:32.050 --> 11:32.620 And here. 11:32.620 --> 11:39.760 Yeah some players might think well obviously colored bishops wants the win chance so rook d free facilitates 11:39.760 --> 11:47.470 kings to and to get this other rook out of bed we have in fact it's lost now the rooks lost with Queen 11:47.470 --> 11:48.490 H one check. 11:49.420 --> 11:50.980 So what's going on here? 11:50.980 --> 11:54.220 If Black Castle's queenside, we're just going to take on h six. 11:54.220 --> 11:57.370 So, yeah, it's it's an interesting position. 11:57.370 --> 11:59.770 There's dual France, there's rookie free. 12:00.220 --> 12:03.310 If the rook moves, there's rookie free pinning the queen to the king. 12:03.310 --> 12:06.310 So this is an interesting simplification. 12:06.310 --> 12:10.170 They'll check taking on a one cup of takes on each six. 12:10.180 --> 12:12.220 Now look at the strength of the past pawn here. 12:12.220 --> 12:15.970 It is increasing in strength but it's obviously called the bishops. 12:15.970 --> 12:16.120 Right. 12:16.120 --> 12:19.690 But the kings in the center now and stranded off the Queen G5. 12:19.690 --> 12:21.910 In fact, Vladimir Haut resigned. 12:23.410 --> 12:27.490 This is too dangerous if f six, Queen G six. 12:28.300 --> 12:28.750 Sorry. 12:28.750 --> 12:36.460 Queen G H is the key move and just and just take on eight if rook the eight white can just play eight 12:36.460 --> 12:43.210 six here and it turns out this pawn now which did give black a bit of counterplay is actually a winning 12:43.210 --> 12:51.460 aspect of the position so rookie free it's it creates win probability that possible so yeah King D seven 12:51.460 --> 12:56.830 for example Bishop G for check here for example eight seven and that pawn super dangerous. 12:59.900 --> 13:00.680 So. 13:01.420 --> 13:06.130 And this this is just one key way of winning the possession. 13:06.490 --> 13:17.230 And if Queen a five rook takes e five just to show Bishop a free check, queen of six. 13:18.430 --> 13:20.860 And the queen Queen is on the way. 13:20.860 --> 13:23.620 So Queen C five Queen takes DA as example. 13:24.010 --> 13:30.640 Hey, there are other ways to win, but the final position is is pretty crushing of the Queen G five. 13:30.790 --> 13:36.850 So, yes, an interesting game showing elements of control and elements of sort of giving a little bit 13:36.850 --> 13:40.390 of counterplay to create a potentially winning pass pawn. 13:40.390 --> 13:42.750 And that did win the game for Karpov in the end. 13:42.760 --> 13:49.150 So there is this balance between control and controversy giving the opponent's counterplay. 13:49.150 --> 13:53.590 But if you're going to get a winning potential passport and sometimes maybe it's a little bit worth 13:53.590 --> 14:02.080 it, Yeah, it's it's an interesting game and not totally classic cop off suffocation strategy but it 14:02.080 --> 14:10.210 was a Sicilian defense and comp have managed to keep control even in these highly sharp tactical situations. 14:10.570 --> 14:14.050 So I hope you got something from this game and so much.
