WEBVTT 00:01.040 --> 00:01.850 Hi there. 00:01.850 --> 00:05.210 In this lecture, we see Anatoly Karpov playing against Joel Attia. 00:05.420 --> 00:11.990 This is in 1995, the Dortmund Sparkasse and tournament around nine D4 from Karpov we have D five from 00:11.990 --> 00:12.610 Nausea, 00:12.650 --> 00:19.060 c4c69c3956369239 00:19.100 --> 00:20.030 BD seven. 00:20.030 --> 00:25.460 This is a very solid looking opening choice by black semi Slav defense. 00:25.520 --> 00:34.490 We have Bishop E two Black castles, white castles, Rookie eight Rook D one Queen e7h3h6a3. 00:34.490 --> 00:40.760 So this is a favorite treatment of Karpov letting Black play 4e5 potentially. 00:40.760 --> 00:45.800 We have D take C four Black doesn't want to play E five immediately. 00:45.800 --> 00:48.110 That would weaken the d pawn. 00:49.010 --> 00:56.600 So we have the on being dissolved first before this e five now knight H four we have knight F eight 00:57.590 --> 01:06.770 and here D tanks E five Bishop takes E five, Bishop D two, Bishop C seven and now 9 to 5. 01:06.770 --> 01:16.430 We have Queen E five looking at H two and comp of defense that with Knight g31 other way if four are 01:16.430 --> 01:19.550 knights just hanging black and just play queen takes F five. 01:19.550 --> 01:24.710 So Knight G three we have Bishop E six here. 01:24.710 --> 01:26.240 You might think, Hold on. 01:26.240 --> 01:29.270 Hasn't Black got an interesting knight? 01:29.510 --> 01:32.720 Five Sure. 01:34.200 --> 01:38.970 Okay, but one can play like f one just to be solid here. 01:39.130 --> 01:42.480 And for example, at five Queen Bee free, this is about even. 01:42.780 --> 01:44.520 It is possible to play that. 01:45.180 --> 01:54.890 So, Bishop e six, Bishop D Free Rook 80 89ce to Bishop be six and they'll be four. 01:54.900 --> 02:00.120 So this gives the idea that White might be interested in trying to inflict structural damage with the 02:00.120 --> 02:06.360 so called minority attack, minority of pawns, attacking majority of pawns over here trying to cause 02:06.360 --> 02:07.410 structural damage. 02:07.410 --> 02:14.100 For example, if White can leave a backward pawn on c six that be interesting or isolate this guy. 02:14.940 --> 02:19.910 So try to cause structural damage 9g6 And you might ask, well, so what about structural damage? 02:19.920 --> 02:25.830 So sometimes pieces are strains when they have to defend pawn structure. 02:25.830 --> 02:31.650 So it's like having a stored advantage that the opponent's pieces are slightly worse, slightly overworked 02:31.650 --> 02:32.610 sometimes. 02:32.940 --> 02:41.850 So we have a4a6 bishops C free queen, G five, and now Bishop D for trying to trade off potentially 02:41.850 --> 02:42.720 dangerous. 02:42.720 --> 02:54.060 Bishop Black obliges nine times for Bishop D five and here perhaps concerned about the tactics a little 02:54.060 --> 03:00.750 bit cop of place what seems to be a natural move E for trying to get rid of this pressure on G two it 03:00.750 --> 03:06.810 turns out here can you see another move which is more tactical in nature, which might actually be worth 03:06.810 --> 03:08.310 trying here? 03:08.310 --> 03:09.150 Can you see? 03:12.050 --> 03:20.810 Yeah, there's a tactical move, 95, which has a threat of effort to try and win material. 03:20.930 --> 03:30.680 So as example, if we take 5f4, then black could sacrifice a piece, of course. 03:30.680 --> 03:37.580 And maybe it looks initially this could be unclear, which is not really karpov's cup of tea, but it 03:37.580 --> 03:43.220 does seem as though it can consolidate like this as example with advantage. 03:43.220 --> 03:47.000 So maybe it was worth trying that move. 03:47.080 --> 03:48.410 95. 03:48.530 --> 03:50.930 But okay, Karpov is human. 03:50.930 --> 03:52.490 Maybe he saw it, maybe he didn't. 03:52.490 --> 03:55.700 But E4 is a bit of an inaccuracy. 03:55.700 --> 04:02.330 Then we could say Bishop E6 came on Knight three, Queen F4 and now Minority Attack. 04:02.480 --> 04:10.340 So we get to see Minority Attack theme though the way it's played 88 times 95 nine takes E five Queen 04:10.340 --> 04:10.880 takes. 04:10.910 --> 04:16.130 It's important to be aware of be aware of the tactics here, acutely aware. 04:16.880 --> 04:19.460 We need to look at the downsides of our own position. 04:19.460 --> 04:24.470 So B takes B takes what you will not not want to do here. 04:24.680 --> 04:27.560 And why for ten points, what do you want to play? 04:28.700 --> 04:35.210 So it seems as though we've dissolved our queenside pawns to give black this backward pawn. 04:35.750 --> 04:37.970 But we shouldn't rush to take it. 04:37.970 --> 04:41.540 If we take it, we create a downside here. 04:42.500 --> 04:43.970 Can you see what that is? 04:45.610 --> 04:46.810 Yeah, but ten points. 04:46.810 --> 04:51.100 What is black play and the fruits of our positional play? 04:51.220 --> 04:52.240 Our disaster. 04:53.620 --> 04:54.940 Rook takes the free. 04:54.940 --> 04:55.510 Yeah. 04:55.690 --> 04:58.450 If rook takes thievery, there's a weakness of the last move. 04:58.750 --> 05:00.010 Neglecting a one. 05:00.010 --> 05:02.000 And tactics are important in chess. 05:02.020 --> 05:02.920 We lose here. 05:02.920 --> 05:06.730 So Rook AC one gently does it. 05:06.730 --> 05:13.990 Rook dd six Queen C4 897 Bishop e2 Rook Tanks dd one check. 05:14.470 --> 05:17.230 So the bishop has to take here. 05:17.350 --> 05:21.220 Otherwise, the queen drops off, the Queen's come off. 05:22.360 --> 05:28.290 So in this position, is it such a big deal with this backward pawn? 05:28.300 --> 05:30.850 There's a bit of strain on a piece. 05:32.350 --> 05:35.140 The Rook f6 92. 05:35.140 --> 05:39.850 There is a potential pass pull now here with the two, two, one. 05:40.540 --> 05:46.420 We have C five and in fact this allows 94 exploiting the pen and hitting the bishop. 05:46.420 --> 05:48.520 Bishop F seven and now another pin. 05:48.520 --> 05:53.500 So it's exploited Bishop G for we have rookie eights. 05:57.330 --> 05:59.910 And now might be five is polite. 06:00.720 --> 06:04.980 So now D seven really has to be addressed. 06:05.070 --> 06:12.840 If it had taken on d7c text E for free, there is rook d eight. 06:12.870 --> 06:16.320 Note Black also has to be careful about their downsides. 06:16.320 --> 06:17.970 If rook takes E four. 06:19.440 --> 06:21.350 That would be disaster for black. 06:21.360 --> 06:25.980 Can you see how tactics rook eight. 06:25.980 --> 06:28.260 Check King eight seven. 06:28.260 --> 06:30.030 Bishop at five Check. 06:30.030 --> 06:31.740 Winning the exchange and winning the game. 06:31.740 --> 06:34.890 Basically the skew skewers the pawn and the bishop. 06:34.890 --> 06:37.320 There's no hope here for playing with best play. 06:37.320 --> 06:38.940 So might be five. 06:40.230 --> 06:43.650 This turns out to be quite a critical moment of the game. 06:43.650 --> 06:45.480 Black is under strain. 06:46.350 --> 06:50.850 Trying to defend C five and plays 96 here. 06:50.850 --> 06:53.600 It seems as though a fight had to be played. 06:53.610 --> 07:00.480 Why directly play 96 here to hit the rook and defend. 07:00.520 --> 07:02.460 Efforts to keep the attack. 07:02.760 --> 07:07.650 So yes, this is delayed gratification for that structural issue. 07:07.680 --> 07:17.730 If rook the eight knights b seven and let's say E two, we can take on C five with a small edge to work 07:17.730 --> 07:18.300 with. 07:18.540 --> 07:22.080 Now, let's say Black had played rookie seven. 07:24.950 --> 07:25.520 Okay. 07:27.660 --> 07:35.550 So in this position we're saying, look, e seven the funny thing is about this, although it seems 07:36.840 --> 07:41.550 that yeah, we can try and cash out with Bishop takes D seven. 07:41.550 --> 07:48.870 Sure, but there's actually a more delicate way of playing this position based on the strain of the 07:48.870 --> 07:50.130 D seven Knights. 07:51.330 --> 07:53.370 It's having to be defended by the rook. 07:53.370 --> 07:58.410 So strain causes strain and it's like we can undermine the pieces here. 07:58.410 --> 08:04.860 With 96, we can actually fraternite c a and you can see that if the rook moves, we're going to take 08:04.860 --> 08:05.400 on D seven. 08:05.400 --> 08:12.240 So what black do here, let's say Bishop Essex then? 08:12.240 --> 08:20.190 Actually, funny enough, in this position we can increase the strain even more with Bishop H five. 08:20.190 --> 08:23.310 Very delicate micro downsides of these pieces. 08:23.310 --> 08:29.400 So this knight's strained, protecting this and the rooks kind of confines protecting the knight. 08:29.400 --> 08:33.120 And actually we're threatening 98 here to win the rook. 08:33.540 --> 08:37.200 So say Knight, then this is definitely losing to a loss of material. 08:37.200 --> 08:38.730 Just rook take C five. 08:38.730 --> 08:42.420 But if black plays something else, King H seven, then 98. 08:42.420 --> 08:43.980 And we're kind of checkmate in the rook. 08:44.220 --> 08:51.390 So it's a funny state of affairs now, even with Best play instead of Knight B six point. 08:51.400 --> 08:57.780 If a black's pieces kind of get tangled up and confused and overworked and there are delicate little 08:57.780 --> 09:03.750 kind of micro piece downsides to try and win material based on their awkwardness. 09:03.750 --> 09:08.340 So, yes, this is just leading to a really awkward position in some cases. 09:08.340 --> 09:11.850 If it's not that case, it's rookie seventh, It's just awkward. 09:11.850 --> 09:14.610 The Rooks protecting the knight, the knight's protecting the pawn. 09:15.030 --> 09:19.620 And apart from the right hitting E4, we're kind of addressing that with 96. 09:19.620 --> 09:23.760 So yes, we're actually threatening 98 now. 09:24.180 --> 09:30.420 It's an undermining attack on the pieces and the pawn, the whole the whole lot is under fire here. 09:30.420 --> 09:37.140 It shows the level of discomfort that's possible, all based on minority text. 09:37.140 --> 09:43.440 So we can say that the minority attack, even in the best case scenario for black, is successful. 09:43.440 --> 09:46.440 It's led to peace, confusion and vulnerabilities. 09:47.280 --> 09:50.070 But with Knight B six, Yeah. 09:50.100 --> 09:53.100 Karpov now plays like RD Sex. 09:54.460 --> 09:56.440 And this is now tricky. 09:56.440 --> 09:57.730 Very, very tricky. 09:57.760 --> 09:59.800 So black plays 94. 10:00.070 --> 10:04.480 If Rook is seven, we can just take on C five Hare. 10:04.480 --> 10:05.320 No problem. 10:05.320 --> 10:07.690 If rook D eight, we can just take on F seven. 10:07.690 --> 10:14.830 No problem then 25 So a four hitting white's rook rook a free rook. 10:15.070 --> 10:16.450 Another past pawn is created. 10:16.450 --> 10:24.100 Now this is more than just straining the pieces slightly, you know, to threaten to get a queen. 10:24.100 --> 10:28.090 Paul spawns sometimes very, very dangerous. 10:28.090 --> 10:30.580 And that's the case here we have Bishop D five. 10:30.880 --> 10:34.450 If F takes E five, F takes this position. 10:35.020 --> 10:36.310 Rook D three. 10:36.460 --> 10:37.540 Bishop C six. 10:37.540 --> 10:38.560 E six. 10:40.260 --> 10:44.190 And you can see that actually the passport is so dangerous here. 10:44.520 --> 10:48.150 C three The rook can get behind the black's past pawn. 10:49.140 --> 10:52.410 And for example, Knight 68 wins material. 10:53.850 --> 10:58.050 If we go back here, Black's really on the string with this past pawn. 10:59.520 --> 11:06.210 And if Bishop D five, Rook c seven this position, we're going to end up playing E seven. 11:06.810 --> 11:07.980 And here. 11:09.460 --> 11:11.680 Let's say Bishop e four group. 11:11.680 --> 11:22.810 We ain't h four and blacks really tied up in knots and is in a kind of near zugzwang if a for releasing 11:22.810 --> 11:25.250 the seventh be able to be used. 11:25.270 --> 11:31.180 We'd use that for rook the eight so we can see how the dangerous passed pawn in action just winning 11:31.180 --> 11:32.710 here in that variation. 11:32.710 --> 11:37.110 But Bishop D five but in this case just E six. 11:37.120 --> 11:39.070 Yeah, that was the stubborn variation here. 11:39.070 --> 11:46.540 Just e six and it looks as though this is terminal E seven resigned actually, and moved 44 If King 11:46.540 --> 11:52.210 of Fe one has rookie free to renew E seven check. 11:53.050 --> 11:57.460 And what does black do this? 11:58.180 --> 12:04.390 It's a very difficult position given that there's 95 F king E seven. 12:05.110 --> 12:10.600 So if black has to give up a piece that's pretty hopeless. 12:10.600 --> 12:15.040 This is just hopeless at five skills, everything. 12:15.040 --> 12:21.640 And if we look again, if rook a seven, then actually knight C eight and if rook be seven, we can 12:21.640 --> 12:26.950 play E seven check here and here we have 96 is checkmate. 12:27.460 --> 12:34.900 So yes, the past pawn in the end was the really decisive factor, not the structural damage, although 12:34.900 --> 12:40.120 that was a distraction for Black having that pressure. 12:40.450 --> 12:47.830 So, yes, a very interesting game from a positional perspective, at least showing how structural damage 12:48.010 --> 12:55.180 can create responsibilities for the opponent's pieces, but also can lead to things like very dangerous 12:55.180 --> 12:56.200 pass pawns. 12:57.310 --> 12:58.720 So I hope you enjoyed this one. 12:59.580 --> 13:00.360 And so much.
