WEBVTT 00:00.840 --> 00:01.630 Hi there. 00:01.650 --> 00:09.120 In this lecture, we see David Janowski against Capablanca in 1916, the Rice Memorial tournament around 00:09.120 --> 00:09.900 free. 00:10.110 --> 00:12.690 We have D4 from Janowski. 00:12.690 --> 00:20.730 Capablanca plays nine 690 3d5c4c6 so the Slav defense nine C free. 00:21.360 --> 00:23.070 And then we see Bishop F five. 00:24.090 --> 00:32.310 Here, if Bishop G for one has 95 and this position, yeah, that tempo gain from white can be useful. 00:32.310 --> 00:36.570 This position has e four so it's quite dangerous for black to allow this. 00:36.870 --> 00:43.560 For example here Queen B free 9c6 queen takes F seven Check is a total disaster. 00:43.560 --> 00:47.790 Yeah, it can be very, very dangerous to play Bishop G four in a nutshell. 00:49.290 --> 00:51.870 So Bishop F five is played. 00:51.870 --> 00:58.290 We have Queen B free, and here Capablanca actually plays Queen B six. 00:58.290 --> 01:00.630 So you might think this isn't a positional move. 01:00.630 --> 01:07.230 Surely the positional player aims to cause structural damage in the opponent's position here double 01:07.230 --> 01:08.460 pawns are being offered. 01:08.460 --> 01:12.420 Furthermore, it's not even that it's even worse than double pawns. 01:12.420 --> 01:13.410 They're isolated. 01:13.410 --> 01:20.570 So Queen takes B six, which is actually technically a mistake, but it seems very lucrative. 01:20.580 --> 01:27.330 But C five might actually be better and allow it should allow double pawns because there's a dynamic 01:27.330 --> 01:32.040 on the file which fully compensates the structural issue. 01:32.220 --> 01:35.190 Yeah, chess is about trade offs. 01:35.190 --> 01:38.130 And here, for example, why it's going to have a small edge. 01:38.130 --> 01:43.650 We're very clear cut plans of B4 b five later and also another positional plan of the knight potentially 01:43.650 --> 01:44.610 coming to a five. 01:44.610 --> 01:49.620 There's a lot of plans in this position which London system players are aware of. 01:49.700 --> 01:56.820 This is often very, very good to get the compensation here, but in this case Queen size B six is played 01:56.820 --> 01:59.520 and it looks even more lucrative after C takes. 01:59.520 --> 02:04.110 It looks as though the weaknesses are being amplified because now these double pawns are isolated. 02:04.110 --> 02:08.520 There's no pawns adjacent to them which can defend, say, B six. 02:08.520 --> 02:15.780 But Capablanca has a great idea here of the 1986 Bishop D two, which defends against Knight before 02:16.080 --> 02:21.720 we have an amazing concept to repair the structural damage. 02:22.350 --> 02:26.190 So yes, this is really quite deep. 02:26.190 --> 02:34.950 This move is Bishop DD seven and we see that this bishop later can support a, B five and 90 C four 02:34.950 --> 02:38.490 plan to try and encourage this pawn being swapped. 02:38.490 --> 02:41.070 What moved to the C file? 02:41.220 --> 02:42.390 So we see this in action. 02:42.390 --> 02:43.440 Bishop E to. 02:45.720 --> 02:52.710 We have E Sex White Castles, Bishop RD, Sex Rock 51 King E seven King stays in the sense of Bishop 02:52.710 --> 02:53.520 C free. 02:53.820 --> 02:56.430 So yes, the positional player with the double pawns. 02:56.430 --> 03:03.660 But the plan to un double with rook fc eight Rook eight rather a free and now 95. 03:03.660 --> 03:07.950 So the threat here concretely is immediately knight be free to fork the rooks. 03:09.480 --> 03:15.480 So we have Knight rd two and now five locks against ee4. 03:15.480 --> 03:22.050 So that's prophylaxis against E four, G four and here it comes now B five. 03:23.640 --> 03:27.230 So black is on the way to installing a knight on C four. 03:27.240 --> 03:30.570 Now you might wonder what about Bishop takes a five. 03:30.900 --> 03:35.460 Well, here black can play rook take C one check Rook take one. 03:35.460 --> 03:36.840 Rook takes a five. 03:36.840 --> 03:41.100 And if we look at the resulting position here, there's not much for Black's fear because B four is 03:41.100 --> 03:44.220 happening anyway to resolve the double pawns. 03:44.220 --> 03:45.240 So this would be fine. 03:45.240 --> 03:49.140 Structurally black would have the bishop here as the small positional advantage. 03:49.260 --> 03:54.750 And if 95 black can even consider bishop take C five because here after the rook takes he five rook 03:54.750 --> 04:00.120 a two, and here the king can go to D six and black might have a small edge here. 04:00.120 --> 04:07.680 So that was a way of playing it for white, but it is giving black a small edge and free is played. 04:07.680 --> 04:13.290 We have 9c4 and in fact, Black's really increasing positional advantages here in two ways. 04:13.290 --> 04:16.080 Getting the bishop pair off to Bishop take C four. 04:16.080 --> 04:20.460 So we have a bishop without counterpart and we're doubling the pawns. 04:20.460 --> 04:22.590 So all of a sudden what a transformation. 04:22.590 --> 04:28.770 This looks like a super solid position that a positional player would really respect their own pawn 04:28.770 --> 04:29.580 structure. 04:30.240 --> 04:33.150 So we have E four and now King F seven. 04:33.150 --> 04:38.610 So not trying to let this bishop escape its prisoner behind its own pawn. 04:40.800 --> 04:41.520 Okay. 04:43.170 --> 04:46.110 And G5 was also interesting here. 04:46.110 --> 04:48.210 If E-5, the bishop would go back. 04:48.300 --> 04:52.310 And here, for example, G takes her four, G takes her four rook G back. 04:52.350 --> 04:56.370 And Bishop f4 Black has a small edge there, but King F seven is played. 04:56.370 --> 04:57.240 We have E5. 04:57.240 --> 05:03.450 This is actually a positional mistake because it means that the structure is more undefinable later 05:03.450 --> 05:05.910 as we're going to see with G five. 05:05.910 --> 05:12.870 So Bishop E seven the intention is f four, but there's an undermine operation available with G five 05:12.960 --> 05:14.640 to try and shake this structure. 05:15.390 --> 05:20.250 So yes, E five was a mistake it seems, with this follow up idea. 05:21.510 --> 05:26.250 So now we have B five, so it's like play on potentially on both sides of the board. 05:26.250 --> 05:30.300 King F2 rook f4 king E free rook C eight. 05:30.540 --> 05:38.070 So there's a fret now of B for we have rook ab1h6. 05:39.570 --> 05:39.960 Yeah. 05:39.960 --> 05:44.970 I mean that threat is is just to see the tactical implication here of B four. 05:44.970 --> 05:45.960 What does White do? 05:46.130 --> 05:48.060 White's losing material. 05:48.300 --> 05:48.770 Yeah. 05:48.780 --> 05:55.260 Because Brook takes say one so the rooks are doubling with great purpose there so rook AB 1h6 so this 05:55.260 --> 06:06.360 undermining operation is possible now we see Knight and 3g5 91 Rook G eight So we have King F3, G takes 06:06.360 --> 06:14.730 our four, G takes our form and the rock on the A file comes back 9g2 Rook G four We have rook G one 06:14.730 --> 06:15.930 Rook ag8. 06:16.890 --> 06:18.180 Bishop E one. 06:19.130 --> 06:20.840 And now Be4 is played. 06:22.550 --> 06:24.650 So, yes, this is really interesting. 06:24.650 --> 06:28.310 It opens up the Lions Square bishop to come into the position. 06:28.940 --> 06:30.890 Yeah, it's making great use of that. 06:30.890 --> 06:35.570 Bishop of that counterpart, Bishop II was possible as well. 06:35.600 --> 06:37.100 There's another way of playing this. 06:37.520 --> 06:43.190 For example, like this, the bishop can come to this side of the board as well with a huge advantage. 06:43.190 --> 06:44.240 This would be crushing. 06:45.530 --> 06:51.500 So that's actually this is in a way, it's more accurate than the games continuations. 06:51.500 --> 06:52.330 Go for the king here. 06:52.340 --> 06:53.330 Just winning material. 06:53.330 --> 06:54.430 Absolutely winning there. 06:54.580 --> 06:56.630 That's really, really dangerous. 06:57.350 --> 07:00.260 And you might wonder, well, what about king of two here then? 07:00.260 --> 07:03.620 B4 here with H5. 07:03.860 --> 07:07.070 This is also great for black in its own way. 07:07.520 --> 07:10.970 So for example, like this black can make progress soon. 07:11.630 --> 07:19.550 For example, we've rook be free rooks doubling on the B file and the rooks can make inroads potentially. 07:19.550 --> 07:25.160 So for example, like this, this is just another illustration where black's going to be better past 07:25.160 --> 07:26.450 pawn is being created there. 07:26.450 --> 07:27.490 So okay. 07:27.530 --> 07:34.610 Before though, this seems super lucrative in its own right to get the bishop into the position of white, 07:34.970 --> 07:38.600 we have eight takes before bishop a four. 07:41.060 --> 07:44.240 So potentially coming into the position now we have rook one. 07:45.690 --> 07:48.450 Bishop see to Bishop Jeffrey. 07:49.320 --> 07:51.030 And this actually makes things a lot worse. 07:51.030 --> 07:57.750 It's actually a relatively big mistake if rook a seven bishop e for take this way of playing things. 07:58.770 --> 08:04.380 White does have a resource here with Bishop H four and it actually leads to an even position. 08:04.380 --> 08:07.110 Believe it or not, this this will be even after all that. 08:07.110 --> 08:07.410 Yeah. 08:07.410 --> 08:14.280 So actually it does seem Rook seven had to be tried here to pin the bishop and for this bishop to make 08:14.280 --> 08:15.990 use of h four sometimes. 08:16.110 --> 08:17.340 But with Bishop G. 08:17.340 --> 08:22.620 Frayne we have Bishop e48 now K to H five rook a seven. 08:22.620 --> 08:23.940 This is too late. 08:23.940 --> 08:25.740 This is far too late now. 08:26.040 --> 08:28.620 The Bishop H four is not going to be available. 08:28.620 --> 08:33.900 We have Bishop takes G two, Rook takes G two, and now H four. 08:34.470 --> 08:36.060 Bishop takes H four now. 08:36.060 --> 08:44.190 But with big penalty, Rook takes G to check king of free and now Rook takes H two White doesn't have 08:44.190 --> 08:47.580 enough compensation here, so Bishop takes E seven. 08:47.580 --> 08:53.130 If rook takes e seven, check King of eight This position rook gh8. 08:54.060 --> 08:56.670 Black's going to get a big advantage here. 08:56.670 --> 08:58.440 Like this, for example. 08:58.710 --> 08:59.070 Yeah. 08:59.070 --> 09:00.360 What is black doing here? 09:00.510 --> 09:01.710 What is white doing here? 09:01.740 --> 09:04.440 Black's going to be meeting with Rook hedge free. 09:04.440 --> 09:05.700 So what is white doing here? 09:05.700 --> 09:15.930 Rather so anyway, Bishop takes e seven was played rook free Check King Have two Rook be free Bishop 09:15.930 --> 09:19.140 G five Check this cover check. 09:19.770 --> 09:22.050 Okay, so there isn't enough here. 09:22.050 --> 09:30.480 King G six rookie seven Rook takes B to check king free and now Rook eight So threatening to make the 09:30.480 --> 09:35.310 king soon we have rook takes e six check King H seven. 09:35.310 --> 09:36.900 And here White resigned. 09:37.680 --> 09:39.720 Now, there was a last trick here. 09:39.720 --> 09:42.990 If the king went to H five, there's real H six. 09:42.990 --> 09:43.710 Checkmate. 09:43.710 --> 09:47.100 So the positional player does need to be aware tactically what's going on. 09:47.400 --> 09:52.290 And here in the final possession if white plays rookie seven, check King G six. 09:53.930 --> 09:56.050 Uh, and white carries on here. 09:56.060 --> 09:57.260 Just King G seven. 09:57.260 --> 09:58.070 Check. 09:58.250 --> 09:59.480 King eight, seven. 10:01.040 --> 10:01.550 Yeah. 10:01.550 --> 10:03.020 And then off the check here. 10:03.530 --> 10:08.770 Rook G two will threaten Rook G for checkmate as an example. 10:08.780 --> 10:11.480 Well, mating, rather mating soon. 10:11.480 --> 10:12.380 So rookie's seven. 10:12.380 --> 10:13.220 Shaq king takes. 10:13.220 --> 10:14.540 This is just hopeless for white. 10:14.570 --> 10:17.900 White's running out of checks essentially and will be mated. 10:18.020 --> 10:21.530 So, yeah, if we look at this final position, it is pretty hopeless. 10:23.390 --> 10:25.010 A check on E seven. 10:25.010 --> 10:29.960 We're just going to play King F eight and then we're looking forward to Champ mating the opponent's 10:29.960 --> 10:30.560 king. 10:32.730 --> 10:36.240 So yes, a crushing game positionally. 10:36.360 --> 10:41.700 And it seems very paradoxical in one sense when you first look at this game and this is a very highly 10:41.700 --> 10:47.370 celebrated positional masterpiece, it seems paradoxical that a positional player would allow such apparent 10:47.370 --> 10:49.740 damage to their pawn structure. 10:49.890 --> 10:57.660 But if there's a plan on top of this to repair the damage with interest and there was, then it justifies 10:57.660 --> 10:58.020 it. 10:58.710 --> 11:05.340 So, yes, there's great queenside play here from black to repair the structure. 11:06.840 --> 11:13.830 So this position white perhaps should have bailed out here with a simple bishop takes a five not allowing 11:13.830 --> 11:19.110 this position because two positional advantages now creep in the repairing of the structure and the 11:19.110 --> 11:19.560 bishop. 11:19.710 --> 11:23.330 And we see that this light squared bishop can be devastating later. 11:23.340 --> 11:25.070 In particular, it's without a counterpart. 11:25.080 --> 11:33.450 So great positional play after incurring structural damage, volunteering structural damage in one's 11:33.480 --> 11:35.610 own position, who would have fought the positional player? 11:35.610 --> 11:38.250 A position player like Capablanca would do this. 11:38.250 --> 11:40.440 But yeah, it makes the game even more beautiful. 11:40.440 --> 11:46.860 This kind of paradox okay for how to handle structure and how double pawns aren't necessarily bad. 11:47.130 --> 11:51.800 You've got to think, are they exploitable and are they repairable? 11:51.820 --> 11:53.340 Are they transformable? 11:53.340 --> 11:58.080 We're going to think about weaknesses in dynamic ways as a positional player, not just that double 11:58.080 --> 12:00.660 pawns are just bad and you can't ever have them. 12:00.990 --> 12:01.750 Okay. 12:02.040 --> 12:02.880 And so much.
