WEBVTT 00:00.840 --> 00:01.650 Hi there. 00:01.680 --> 00:04.830 In this lecture, we learn a little bit more about the Roy Lopez. 00:05.250 --> 00:10.050 Many grandmasters have said if you mastered Roy the pads, you really start to master chess. 00:10.050 --> 00:13.110 And we see Anatoly Karpov from the black side of a roller. 00:13.110 --> 00:18.400 Pettitte against Roginsky in the 1966 Masters candidates tournament Round four. 00:18.420 --> 00:24.670 So E-4 from Roginsky and we have E five 9396 but should be five. 00:24.690 --> 00:32.150 So Roy Lopez a six bishop a4956 White castle's bishop e seven and now Queen Ito. 00:32.160 --> 00:34.680 This is an anti Marshall gambit move. 00:34.710 --> 00:38.730 The Marshall Gambit, even in 1966, was pretty respected. 00:38.880 --> 00:40.680 So it's an interesting move. 00:40.680 --> 00:48.510 We have B five, bishop B three, D, six, C, free black castles, rook D one. 00:48.510 --> 00:52.020 So this is a slightly unusual configuration. 00:52.020 --> 00:55.470 Usually in the royal pairs, the queen is on D one and a rook is on E one. 00:56.160 --> 01:06.360 So Karpov plays a five Bishop C2 and now C5 D four Quincy 7h3 rookie eight D tanks e5d tanks, E five. 01:06.390 --> 01:07.590 Knight BD two. 01:08.190 --> 01:13.950 And here there's an opportunity to try and get a pair of rooks off and Rook D eight is played. 01:13.950 --> 01:20.970 So there's a slight penalty if 9f1 pair of rooks coming off means there's less attacking potential and 01:20.970 --> 01:29.310 Black's queenside expansion would be less dangerous if White has more complexity with more pieces. 01:29.310 --> 01:31.620 So this is an interesting move for simplification. 01:31.840 --> 01:32.610 Knight Have one. 01:32.610 --> 01:35.700 We have a pair of rooks coming off and now C4. 01:36.030 --> 01:40.890 And the thing is also taking off a pair of rooks weaken slightly the D free squares. 01:40.890 --> 01:46.440 Sometimes it might be possible to manoeuvre a knight into the D free square. 01:46.440 --> 01:50.910 I mean at the moment it's adequately guarded, but that is one square which might be of interest later 01:50.910 --> 01:51.690 to black. 01:51.840 --> 01:54.450 But there's another thing about this position. 01:54.450 --> 02:03.210 The free to free is not a pawn majority, but if we're imaginative with this, we can potentially create 02:03.210 --> 02:03.960 a pass pawn. 02:03.960 --> 02:10.320 Imagine the knight not being there and we go for this with b4 b free. 02:10.320 --> 02:18.210 We could transform it into a virtual pawn majority If we had two pawns here and white had two pawns 02:18.210 --> 02:22.530 there, we'd have much more potential for a past pawn. 02:23.480 --> 02:27.740 So even though it's free again is free, there's a pass -- potential in this position with a bit of 02:27.740 --> 02:28.760 imagination. 02:29.660 --> 02:35.030 So yeah, just imagine two black pawns here and two white pawns here. 02:35.120 --> 02:40.880 And then if we took out beta, we'd have a dangerous be free pass pawn only two squares away. 02:40.880 --> 02:42.470 So just bear that in mind. 02:42.830 --> 02:49.160 We see Bishop G five, Bishop E six, Queen E, two Knight B seven Knight G free. 02:49.160 --> 02:55.910 And now, yeah, there are concerns about 95 we have G six, which is a principled move, it turns out 02:55.910 --> 02:56.480 here. 02:56.480 --> 02:58.310 It's also a slight inaccuracy. 02:58.310 --> 02:59.720 That's the thing with principle moves. 02:59.720 --> 03:02.840 Are they actually to do with the specifics of the position. 03:02.840 --> 03:11.090 It seems more accurate is h six and if Bishop takes Bishop takes 595 blacks should be slightly better 03:11.090 --> 03:12.110 in the game. 03:12.110 --> 03:20.300 G six is played, but White doesn't really sniff the tactical potential of this slight weakening move 03:20.690 --> 03:22.790 and actually plays Rook RD one. 03:22.790 --> 03:29.030 There was an opportunity, but this is beyond most humans, unless they're like Tao or Shirov attacking 03:29.030 --> 03:29.300 players. 03:29.300 --> 03:32.630 Knight at five is actually rather dangerous here. 03:33.440 --> 03:40.730 If Bishop debates Knight H six, Jack and Rook RD one this is starting to be quite dangerous for white. 03:41.920 --> 03:48.640 And if it's got a bit of danger and if here the point of a piece like getting two pawns, but then there's 03:48.640 --> 03:52.630 potential for G four and it starts to get quite scary. 03:52.840 --> 03:56.230 This position, for example, is quite scary business. 03:56.230 --> 03:57.340 And what ends up? 03:57.550 --> 03:59.320 Technically better. 03:59.560 --> 04:02.320 But yeah, this requires quite a bit of imagination. 04:02.320 --> 04:03.610 There's a poor mess over here. 04:03.610 --> 04:05.020 There's a knight over here. 04:05.170 --> 04:07.540 These pawns kind of a kind of useful. 04:07.540 --> 04:12.790 And there's attacking potential, which is difficult actually, to tame in this position. 04:12.790 --> 04:14.380 So that kind of thing is scary. 04:14.380 --> 04:21.400 But White played rook D one and we have another pair of rooks coming off the moments gone from 95 totally. 04:22.900 --> 04:24.910 So here if a five. 04:24.910 --> 04:27.370 Yeah, Black just takes on D one and there's nothing special here. 04:27.370 --> 04:29.380 Black's just a piece up. 04:29.830 --> 04:31.240 So rook tanks D eight. 04:31.240 --> 04:38.170 So with the rooks coming off this plan, this creative plan with the free to free to actually squeeze 04:38.170 --> 04:40.870 water out of a stone, you know, squeeze blood out of a stone. 04:40.900 --> 04:44.830 It is possible to create a pass pawn here, even though it's free against free. 04:44.830 --> 04:47.980 So that's a remarkable thing about this game we're about to see. 04:47.980 --> 04:49.270 97. 04:49.270 --> 04:52.360 This is nice for weakening on the dark square. 04:52.360 --> 04:56.590 So getting rid of the dark square defender means F four, C five. 04:56.590 --> 04:58.630 These these are more accessible for black. 04:58.630 --> 05:01.000 So Black is doing very well here. 05:01.180 --> 05:07.060 Queen 86 and now there is a fret of G five so that stops with F six. 05:08.170 --> 05:10.120 We have you know it's. 05:10.830 --> 05:14.920 If it's not played yet, it's too dangerous for 95. 05:14.940 --> 05:19.470 If nothing else, if a five also nine five here is good. 05:19.680 --> 05:26.000 This position with F six threatening Queen G seven mate is going to be in White's favour. 05:26.010 --> 05:27.650 That Bishop is also great here. 05:27.660 --> 05:29.430 That's great for the Royal affairs Bishop. 05:29.610 --> 05:30.900 And if C six. 05:30.900 --> 05:32.280 Yeah, 9g5. 05:32.280 --> 05:39.930 And this is dangerous, this is far too dangerous because H five So there's a lot of problems here. 05:39.930 --> 05:45.730 So for example, Queen takes H seven even though it's not mating on F seven, nine takes E six. 05:45.750 --> 05:46.470 Ouch. 05:46.710 --> 05:47.960 And then winning the queen. 05:47.970 --> 05:55.440 So yeah, it's it's a very important to play to stop that possibility. 05:55.440 --> 05:57.660 And here this is also in White's favour. 05:58.650 --> 06:01.500 So f six important Queen E free. 06:01.500 --> 06:03.770 So Karpov has sorted himself out. 06:03.780 --> 06:07.530 He's put himself beyond the feet in a way before going on the attack. 06:07.800 --> 06:10.010 But the attack is on the Queen's side. 06:10.020 --> 06:12.420 He's put himself beyond the feet on the king's. 06:14.190 --> 06:15.520 And now it's Karpov's turn. 06:15.540 --> 06:20.160 a5h for White's still trying to get some sort of attack b four. 06:20.280 --> 06:24.270 So this dream, dreamy idea of this kind of 2 to 1. 06:25.480 --> 06:29.620 Pawn chain, if we have 2.7 is only one there, we've got a majority. 06:29.620 --> 06:37.420 Even though if we took the whole of the free kind of fouls, it is in principle free to free. 06:37.420 --> 06:41.860 But yeah, without this imagination for the past more, we're not going to be able to play like Karpov 06:41.860 --> 06:42.010 here. 06:42.010 --> 06:44.980 We need this imagination for the past pawn potential. 06:44.980 --> 06:46.840 So H five King G seven. 06:47.230 --> 06:53.650 Bishop D one if h six check King F 890 2957. 06:53.650 --> 06:58.780 And if we can think in terms of passports or passport potential, even though it's outrageous, we're 06:58.780 --> 06:59.650 thinking positioning. 06:59.650 --> 07:02.200 We're not just thinking as a mass of variations. 07:02.410 --> 07:04.780 We're thinking in the domain of chess. 07:04.780 --> 07:08.620 You know what's great in the domain of chess rather than specific variations. 07:10.780 --> 07:13.630 And, you know, that's a bit like domain driven design in programming. 07:13.630 --> 07:17.230 You know, you think about the domain of chess, what is actually, you know, great assets. 07:17.230 --> 07:21.180 A pass -- is a vivid like winning probability assets have. 07:21.190 --> 07:23.530 So if we can think positionally, that's just brilliant. 07:23.530 --> 07:27.520 But here let's see so Bishop rd one we have nine of seven. 07:28.510 --> 07:31.600 Yeah white didn't really benefit from H six check here. 07:31.600 --> 07:33.340 The form point here is is a bit futile. 07:33.340 --> 07:35.020 It's actually a bit of a weakness after nine of seven. 07:35.020 --> 07:36.490 It's just continually targeted. 07:36.490 --> 07:40.450 But I could try and get the Queen's off and then prove that it's weak, you know, take it off later. 07:40.450 --> 07:40.840 So. 07:40.840 --> 07:49.960 Bishop dd 1957 we have HD HD 9295 and we can see that B free is on the way now. 07:50.290 --> 07:55.870 And also it's, it's, you know, the bishops guarding a fork because sometimes a fork will be useful 07:55.870 --> 07:57.910 to hit that poor B to pawn. 07:57.910 --> 08:00.190 This is a kind of disconnected pawn in it's game. 08:00.190 --> 08:01.840 It's difficult to defend B two. 08:01.840 --> 08:03.160 We have B free. 08:03.370 --> 08:05.730 It's a difficult position already for one. 08:05.740 --> 08:13.150 If 92, let's have a look at this queenly sex free as example here, be free. 08:13.150 --> 08:18.160 We get that ideal and then let's say 93 how is white defending B two? 08:18.160 --> 08:24.160 So even though there is no vivid poor majority, he beats it because B two is going. 08:24.160 --> 08:28.450 This is a fast passed pawn after this is just going to be a crushing position. 08:28.600 --> 08:33.880 And yeah, that d free square is a disaster in that regard for Black's use, it's great for Black to 08:33.880 --> 08:34.030 use. 08:34.030 --> 08:41.290 So if Bishop E to be free and we reach that dreamy structure where we have a 2 to 1 in effect here and 08:41.290 --> 08:47.080 also B2 is is difficult to defend but this position 90 6a4 Yeah. 08:47.080 --> 08:58.390 Black's just doing really well here so we have B free C tanks, eight tanks and now Queen B 696 is also 08:58.390 --> 09:00.010 a decent enough move, it seems. 09:00.010 --> 09:09.010 You know, this position of might be 5c4 97 Black's getting a significant advantage here so be free. 09:09.010 --> 09:12.580 We have C tanks, B free, eight tanks, Queen B six. 09:14.140 --> 09:17.620 So back to the game 9gf1 is an inaccuracy. 09:17.620 --> 09:19.630 It makes things slightly worse for white. 09:19.660 --> 09:27.430 If 92 Queen de sex is a nice move and here it's waiting for what white to do. 09:27.460 --> 09:27.790 Here. 09:28.600 --> 09:33.580 Have a look at Queen C six for a moment then knight G five looking at e four. 09:33.580 --> 09:36.940 And if every bishop F seven black just stands really well here. 09:38.050 --> 09:43.390 So gf1 90 6c4. 09:44.380 --> 09:50.080 So why c four that looks commit to it looks like it's weakening default even more and it makes this 09:50.080 --> 09:57.430 2 to 1 more apparent for creating a real pass pawn if King H two The problem is one of the problems 09:57.430 --> 10:01.000 B tanks, queen tanks then actually just e four drop. 10:01.000 --> 10:03.520 Simply there's pressure on E for all time. 10:03.520 --> 10:08.890 So C four we have Queen C six, Bishop C two, and now a four. 10:08.890 --> 10:14.560 So here it comes, this 2 to 1 where it was a kind of 2 to 2 if you took those free files. 10:14.560 --> 10:16.510 But now a passport is being generated. 10:16.510 --> 10:21.880 B takes learn, behold, or rather behold the past pawn we have now. 10:21.880 --> 10:27.360 Bishop take C4 cup is very tempo cautious it seems with Bishop Take C four. 10:27.370 --> 10:29.050 Perhaps he considered knight. 10:29.050 --> 10:33.790 Take C for this position with 92 to be interesting for white, but it's not. 10:33.790 --> 10:34.360 Actually. 10:34.360 --> 10:36.400 This position is rather good for black. 10:36.880 --> 10:39.220 It's just black's got a big advantage here. 10:40.720 --> 10:42.940 And if a five queen B five. 10:42.940 --> 10:44.230 Yeah, that pawn is not going anywhere. 10:44.230 --> 10:47.470 We can snap off, be free and take him with advantage. 10:47.470 --> 10:52.990 So actually, it seems as though 1964 was playable, but Bishop takes C four. 10:52.990 --> 11:02.980 It's dangerous for white Knight G three if Knight takes c496c for this position is going to be just 11:02.980 --> 11:03.790 better for black. 11:03.820 --> 11:06.070 You know, there's torture coming with the default square. 11:06.070 --> 11:13.270 So Och Knight G three we have Bishop going back a five and now Queen B five. 11:13.270 --> 11:17.500 So things are getting behind this past pawn potential we have now. 11:18.490 --> 11:22.330 F four Yeah, Queen takes a five. 11:22.330 --> 11:23.860 So a pawn up as well. 11:23.860 --> 11:25.240 It's, it's kind of terrible. 11:25.240 --> 11:27.700 White's position F takes e five. 11:27.730 --> 11:29.320 It's falling apart now. 11:29.470 --> 11:33.940 But if F five there is queen a one check and here Queen D four. 11:33.940 --> 11:35.500 And that's going to be winning for black. 11:35.740 --> 11:41.890 So F takes E five, Queen a one check king of two queen takes E five, 9 to 3. 11:41.890 --> 11:47.970 So a pawn up, big past pawn created from seemingly nothing but imagination. 11:47.980 --> 11:51.550 Queen B two is now a brilliant move. 11:51.550 --> 11:54.010 This is actually a brilliant tactical move. 11:54.280 --> 11:59.830 And yeah, it required great vision here because otherwise it looks as though Black's losing a piece. 11:59.830 --> 12:01.150 Why has Black gone into this? 12:01.150 --> 12:03.130 Isn't black losing a piece? 12:03.700 --> 12:08.820 Yeah, but Karpov had seen this, so actually from here, Karpov had seen that the C. 12:08.950 --> 12:17.110 Life is not really an under protected piece because 93 so black plays queen bee two so temporary a piece 12:17.110 --> 12:21.640 sack by the past pawn is the difference now which makes things wonderful. 12:21.640 --> 12:26.860 So be free and black is at least getting the piece back and more. 12:26.950 --> 12:29.500 So the thing is, if Queen takes these six. 12:29.530 --> 12:31.120 Be take two. 12:31.120 --> 12:34.030 And it's difficult because it's going to be check against the king. 12:34.030 --> 12:39.820 It's difficult to stop that pawn might have five check is is a try and for example here Queen G free 12:39.820 --> 12:42.790 check queen free check check. 12:42.790 --> 12:44.440 Black can actually get out the checks. 12:44.440 --> 12:46.120 Can you see how in this position. 12:50.330 --> 12:50.750 Yeah. 12:50.960 --> 12:52.310 Bishop 85. 12:52.430 --> 12:55.850 Then there's no checks, because thanks to the double pawns. 12:56.060 --> 12:57.350 And then we're going to Queen. 12:57.350 --> 12:59.210 And then all our worries are over. 12:59.210 --> 13:01.010 After Queen's 78, we're just winning. 13:01.010 --> 13:04.100 So anyway, 94, though, was was played. 13:04.280 --> 13:05.960 And here be take two. 13:05.960 --> 13:07.010 And this is crushing. 13:07.010 --> 13:11.770 Even though the part spawns all that work to create the passport and just to lose it. 13:11.780 --> 13:16.440 But in this particular configuration, two against two, it's still winning for black. 13:16.460 --> 13:18.680 Tactically, now white has to resign. 13:18.680 --> 13:24.140 If Queen takes C2, Queen takes RD for check if Knight takes C2. 13:24.170 --> 13:25.730 Can you see what black plays? 13:29.290 --> 13:29.590 Yeah. 13:29.920 --> 13:32.250 Sorry for interrupting the protection of C two. 13:32.260 --> 13:33.430 It's brutal. 13:33.430 --> 13:34.790 And then just winning material. 13:34.810 --> 13:38.200 If D two, C four. 13:38.530 --> 13:42.400 And then what's going to stop C one queening if E five. 13:43.720 --> 13:45.480 It doesn't matter, we queen. 13:45.690 --> 13:50.990 And then here it's Czech as well, so that there's no king safety issues. 13:51.030 --> 13:53.310 So a very, very interesting game. 13:53.310 --> 13:57.390 Very simply played and strong by Anatoly Karpov. 13:57.420 --> 14:03.810 It's like he did put himself beyond the feet before going on the attack, but not in the attacking mindset, 14:03.810 --> 14:09.720 in a positional mindset beyond the feet in terms of his King safety going on attack, in terms of creating 14:09.720 --> 14:10.840 a pass pawn. 14:10.860 --> 14:16.710 So it's still the same principles as an attacking player, but for a kind of positional agenda. 14:16.740 --> 14:20.310 The positional mindset is really expressed well in this game. 14:20.310 --> 14:25.290 If we can get into that mindset like creating passed pawns on the black side of royal affairs, I'm 14:25.290 --> 14:30.180 sure we'll all be playing the royal affairs in a much more dangerous, effective way like Karpov here. 14:30.180 --> 14:32.370 So I hope you enjoyed this game as much as me. 14:33.060 --> 14:33.870 Thanks very much.
