WEBVTT 00:01.130 --> 00:01.870 Hi there. 00:01.880 --> 00:05.990 In this lecture, we see Anatoly Karpov playing against Andrey Keratin off. 00:06.080 --> 00:16.820 This is in 1988, the 55th US Championship round 1c4 from Karpov we see e69c3d5d4 knights have six, 00:17.120 --> 00:19.610 C takes D five, E takes D five. 00:19.610 --> 00:23.330 So this leads to the so called cold mad structure. 00:23.330 --> 00:26.000 Quite often so Black is playing C6. 00:26.000 --> 00:30.080 The Carlsbad structure allows the classic minority attack. 00:30.080 --> 00:35.810 So if we think of the minority attack as a minority of pawns attacking a majority of pawns, you might 00:35.810 --> 00:41.240 think usually don't you need the majority of pieces for the attack to be successful? 00:41.240 --> 00:43.070 It's a structural attack. 00:43.520 --> 00:47.750 So basically it's good to have a minority. 00:47.750 --> 00:52.070 In a way, we've got the semi-open C file, which which makes the danger great. 00:52.070 --> 00:58.160 If White can play A three, B four and as example, say why it was able to take on C six, why don't 00:58.160 --> 01:05.870 we succeed in creating a backward pawn on that semi-open C file and also isolating the a pawn? 01:05.870 --> 01:09.320 So it's about isolating and weakening pawns in general. 01:09.320 --> 01:13.460 So even though it's a minority, it's a dangerous structural proposition. 01:13.460 --> 01:22.820 If White can do this, we see Bishop D free Black castles, Queen two rookie, eight white castles, 01:22.820 --> 01:23.390 nice F eight. 01:23.390 --> 01:27.470 So H seven is securely defended by both knights here. 01:27.890 --> 01:36.320 So even if Bishop takes the other knights holding h seven, we have h three Bishop e6 Rook fc196 to 01:36.320 --> 01:36.890 d seven. 01:36.890 --> 01:43.280 So offering the exchange of bishops comp off rejects that it is possible it seems to take on e seven 01:43.280 --> 01:44.510 for advantage. 01:44.510 --> 01:51.110 White can actually play b four here, believe it or not, and get on with the minority attack. 01:51.140 --> 01:54.110 If Queen takes b for this situation. 01:54.320 --> 01:55.160 Job done. 01:55.160 --> 01:56.390 It's kind of fragmented. 01:56.390 --> 02:01.100 Black's pawns and white's getting a certain advantage here. 02:01.280 --> 02:08.300 Even if all the rooks came off, White's getting a nice blockade square in front of that backward pawn 02:08.480 --> 02:10.610 and this should be a small edge for white. 02:10.610 --> 02:17.780 So this is possible and the advantage could transform into a nice knight on D four or this situation. 02:19.010 --> 02:24.320 So potentially Bishop takes C eight here and this situation where White's getting a much better end 02:24.320 --> 02:25.760 game a pawn up there. 02:26.150 --> 02:28.580 So yeah, there are interesting possibilities. 02:28.760 --> 02:33.830 And also if Knight 57 we still got Bishop takes H seven there, so that was possible. 02:33.830 --> 02:41.150 Bishop 6e7 we have Bishop four though, might be six, Rook A, B one and Bishop D six. 02:42.320 --> 02:49.370 So here actually plays nicely to being able to recapture on that four nicely. 02:49.370 --> 02:56.480 So Knight G six and now yeah, Bishop takes D six is played here, Queen takes these six and you might 02:56.480 --> 02:58.820 think given what we've said will be four. 02:58.850 --> 03:06.800 The thing is in this situation Black does have it's not that easy here black does have 9c4 potentially 03:08.000 --> 03:13.460 let me put that arrow correct and C four and that will blunts White's activities there. 03:13.460 --> 03:23.000 So actually Karpov starts with a four rook eight, Quincy five And here, yeah, this is tactically 03:23.000 --> 03:23.990 justifiable. 03:23.990 --> 03:25.940 It's not losing a pawn or anything. 03:26.240 --> 03:32.390 If Queen takes one, it's going to get ad4 for the knight, but also more significantly B free winning 03:32.390 --> 03:33.800 material, winning that knight. 03:33.980 --> 03:36.170 So the queen goes back. 03:37.640 --> 03:41.210 Another queen parks on a free if a five. 03:41.210 --> 03:43.370 We can see 90 C four is a nuisance. 03:43.370 --> 03:44.180 Be free. 03:44.180 --> 03:49.220 If the knight gets the D six, it's holding things up against the minority attack. 03:49.220 --> 03:50.510 It makes black more solid. 03:50.510 --> 03:54.590 So this situation why only has a small edge. 03:55.040 --> 03:56.270 So queen a free. 03:56.270 --> 04:01.790 We have a six again here Knight C four could be useful for black so a six say. 04:01.790 --> 04:07.220 And then if the knight's on D six black could consider B five here as example. 04:07.220 --> 04:09.890 And it limits White's advantage. 04:09.890 --> 04:13.250 This is a good defensive strategy actually. 04:13.250 --> 04:15.140 So but A-6 was played. 04:15.140 --> 04:25.790 We have Rook C free queen C seven rook BC one rook eight if 90 C four It does seem as though Black could 04:25.790 --> 04:28.130 put up stubborn resistance like this. 04:28.700 --> 04:31.520 So yeah, I mean, there are no guarantees. 04:31.520 --> 04:33.560 This is not a losing pawn structure anything. 04:33.560 --> 04:38.120 It is a game and it would be technically about even here. 04:40.040 --> 04:43.520 And you can see that black's making it difficult to play B four. 04:43.520 --> 04:49.340 So Rook eight though, was played 90 to a five here. 04:49.340 --> 04:53.360 If Knight's F Eights, then B four. 04:53.360 --> 04:59.990 And Queen B free does leave dangers for why four black here after B five and actually all. 05:00.120 --> 05:04.610 So tactics flying say this position a 5.8. 05:04.620 --> 05:06.170 Can you see what one can play here? 05:06.180 --> 05:12.780 The tactics do flow from this as well with that backward C pawn that pressure on the C file and the 05:12.780 --> 05:14.880 pawn is pinned, we can exploit that. 05:14.880 --> 05:15.420 Five points. 05:15.420 --> 05:16.200 What would you play? 05:17.010 --> 05:18.030 Queen 65. 05:18.030 --> 05:21.480 Yeah, that would be a tactical fruit from the positional play. 05:21.780 --> 05:28.470 So anyway, 85 is played rook P 198 and here. 05:28.470 --> 05:28.710 Yeah. 05:28.710 --> 05:31.200 It's not quite a conventional minority attack. 05:31.500 --> 05:35.790 It's one that is trying to be stopped and seeing what can we do from here. 05:36.240 --> 05:43.260 So still it seems as though it has other advantages after might be free bishops. 05:44.790 --> 05:52.890 If Bishop f five then White could take on F5 and this position is going to be a small edge. 05:52.890 --> 06:03.540 So Bishop C eight we have a 590 7g3g6, Rooks goes back H five and now Rook one. 06:03.540 --> 06:08.820 So there is a kind of still a structural attack of sorts with a six trying to weaken. 06:08.820 --> 06:11.760 C six undermine this pawn chain. 06:11.760 --> 06:20.680 Basically we're standard undermining in a way h4f1 bishop and five bishop E two We have 94 and now Knight 06:20.730 --> 06:25.260 C five and here really black could have put up more resistance than what they did. 06:25.260 --> 06:26.010 It seems. 06:26.010 --> 06:34.110 Knights C five helps White Rook A seven was possible and for example here with 92 this position would 06:34.110 --> 06:38.220 be a stubborn position for black to play for. 06:38.220 --> 06:40.920 And you know, it's only about even actually. 06:41.160 --> 06:49.770 But in the game with Knight 65 this helps Karpov significantly after queen take C five this is nice 06:49.770 --> 06:56.730 and also D takes as nice as well because here we could go for a situation as well as hitting the h pawn. 06:56.730 --> 06:58.230 We could ignore that for the moment. 06:58.230 --> 06:59.580 We can actually play like this. 06:59.580 --> 07:04.530 Just positionally forget trying to win material and just perch the knight on D four and play from this 07:04.530 --> 07:05.190 position. 07:05.190 --> 07:06.600 This is really nice. 07:06.900 --> 07:10.050 So Queen takes C five though is nice as well. 07:10.050 --> 07:17.040 Bishop E six like DD 295 Knights F eight, Queen D eight and now a six. 07:17.040 --> 07:22.560 So trying to break down the structure B tanks undermining the structure. 07:23.010 --> 07:28.380 If rugby eight we can see that we're going to undermine the structure and take out C six without any 07:28.380 --> 07:29.100 fuss. 07:29.490 --> 07:34.710 So B takes was played, rook takes a six and yeah. 07:34.710 --> 07:39.810 And black starting to crumble here that pawn chain is crumbling under the weight of pressure. 07:39.810 --> 07:47.220 So Queen eight if not E seven, we can actually take the time out here to take that h pawn, that cheeky 07:47.220 --> 07:48.810 h pawn lying around. 07:48.810 --> 07:49.890 And this is a big advantage. 07:49.890 --> 07:53.100 Then carry on, bring them back to talk to your C six. 07:53.100 --> 07:55.110 So Queen eight was played. 07:55.530 --> 07:57.120 Black's getting dismantled now. 07:57.120 --> 07:59.370 Queen C six Queen. 07:59.370 --> 08:00.000 Thanks, Rook. 08:00.030 --> 08:00.630 Thanks. 08:01.800 --> 08:03.690 So yes, just to pawn down. 08:03.690 --> 08:06.600 But White dominates the position of the Bishop de free. 08:06.600 --> 08:09.120 Actually, Black generously resigns. 08:09.480 --> 08:14.530 It looks as though he was under fire and threatening to basically win another pawn. 08:14.550 --> 08:20.910 It's a very difficult position for black hair given that black is going to lose another pawn. 08:20.910 --> 08:23.970 It's just misery that the bishop is not a great bishop. 08:23.970 --> 08:29.130 So Black generously resigned here just to take it a bit further, you know, check. 08:29.130 --> 08:29.970 So what? 08:30.300 --> 08:37.950 And yeah, I mean, when it's going to be winning material for the night retreats, we can play Rook 08:37.980 --> 08:40.950 See seven to gain a tempo. 08:41.400 --> 08:46.620 And for example, here, just taking an H for two pawns up, there's no real counterplay for black, 08:46.620 --> 08:48.390 so it's a very neat game. 08:48.870 --> 08:50.430 I'll take it to that game and possession. 08:50.430 --> 08:54.680 It's very neat game with a kind of other story of the minority. 08:54.930 --> 08:57.480 If it's prevented, what could happen? 08:57.480 --> 09:02.070 We still have structural goals to undermine the pawn chain, to weaken pawns. 09:02.070 --> 09:03.690 That's the key consideration. 09:03.690 --> 09:07.920 Weakening pawns don't get carried away by the classic concept of minority. 09:07.920 --> 09:08.790 Take more. 09:08.790 --> 09:11.970 The goal of it is to weaken pawns, weaken structure. 09:12.240 --> 09:18.180 Okay, so this is quite a good illustration of the goal of minority attack and how it could be kind 09:18.180 --> 09:24.210 of slowed down or the impact taken out in some of the variations we saw, especially with knights come 09:24.210 --> 09:24.810 into D six. 09:24.810 --> 09:29.430 That's a classic method to try and make the black position more solid. 09:29.550 --> 09:33.300 Okay, I hope you enjoyed this one and so much.
