WEBVTT 00:00.780 --> 00:01.640 Hi there. 00:01.650 --> 00:06.640 In this lecture, we see Anatoly Karpov playing against Alexei Shirov in 1992, the Build tournament 00:06.640 --> 00:16.950 to round 13 D4 from Karpov we have d5 C4 C6 9c396e free e6939 87. 00:16.950 --> 00:19.140 So pretty standard stuff so far. 00:19.260 --> 00:28.020 Queen C2 we have Bishop dd six, Bishop E2, Black Castles White Castles dd ten C4. 00:28.020 --> 00:38.130 Bishop take c4 b5 Bishop E2 Rookie eight So usually black is playing 4e5 cop of weights for this rook 00:38.130 --> 00:40.950 dd one We have Queen seven and now be free. 00:41.490 --> 00:42.950 Black does commit to E5. 00:42.960 --> 00:52.020 There is a certain element of weakening light squares with pawn on E five we have H three so here this 00:52.020 --> 00:55.580 safeguards h two against the battery. 00:55.590 --> 01:02.820 Here we have Bishop B seven if e four This doesn't do anything, it just loses a pawn 92 and just take 01:02.820 --> 01:06.330 in a pawn like this with the C Knight. 01:07.770 --> 01:11.250 Well either is okay so that's not doing anything. 01:11.250 --> 01:20.070 So Bishop B seven we have Bishop B to a six now D takes E, five, 96 five and now a four. 01:22.360 --> 01:28.600 So here we have Rook 88 and now Knight G five. 01:30.250 --> 01:35.970 There are some interesting ideas here of playing 94 to try and remove the defender. 01:35.980 --> 01:37.690 The Queen is looking at age seven. 01:38.410 --> 01:42.310 We have queenly seven and now C for Knight takes E four. 01:42.310 --> 01:43.750 Knight takes E four. 01:45.750 --> 01:48.150 So if the queen took him, there's Queen text G five. 01:48.150 --> 01:49.290 So it takes E four. 01:49.290 --> 01:56.610 But looking at the bishop, Bishop B four and G three, Black's like squares are looking a little bit 01:56.610 --> 01:57.720 vulnerable here. 01:57.990 --> 02:00.630 This already looks like a very interesting position. 02:01.170 --> 02:04.170 An F6 weakens the line squares even further. 02:04.560 --> 02:11.040 Better would have been g six it seems, and this looks a bit silly because of the bishop on B two, 02:11.040 --> 02:15.000 but maybe it is the best course of action to limit White's advantage. 02:15.000 --> 02:21.150 So say taking on a four and and C five white does have an advantage, but it's actually better than 02:21.150 --> 02:23.520 the game after F six. 02:23.520 --> 02:31.260 There's a very interesting move here which reflects a common tool that you'll see used even by the top 02:31.260 --> 02:32.820 neural network sometimes. 02:34.360 --> 02:39.420 It's good to amplify Lion Square bishops by giving up a bishop of the other color. 02:39.430 --> 02:44.170 So sometimes when you give up your dance choir, Bishop, you're removing and removing a knight. 02:44.590 --> 02:48.910 You're mathematically securing sometimes an advantage on Knight Squares. 02:48.910 --> 02:55.270 This piece won't be able to be participating in the lite square activities around the board. 02:55.510 --> 03:02.560 So Bishop takes EY five, creates a mathematical superiority in effect on the light squares. 03:02.560 --> 03:04.330 We have Queen Tang's E five. 03:04.570 --> 03:10.190 If we look at F takes E five for the moment, that looks bad for isolating the pawn. 03:10.210 --> 03:14.050 If Bishop de Frame what is black do here? 03:14.050 --> 03:21.220 If h six we have a commanding position after Bishop E four let's say rook f eight we could simplify 03:21.220 --> 03:28.000 a bit and get a very commanding position here with a clear advantage of the Queen. 03:28.000 --> 03:32.560 E two We've got a lot of interesting prospects for attack as well. 03:32.800 --> 03:40.270 If g six we can actually play h four trying to lure the queen away a bit more, otherwise we're going 03:40.270 --> 03:42.850 to undermine the pawn chain with h five. 03:42.940 --> 03:47.830 But let's say queen size h four here we got a very we have a very strong attack. 03:48.040 --> 03:56.440 So this position, for example, plank starts to lose material pretty soon after 95 and let's say rook 03:56.440 --> 04:05.140 gains queen 65 check King of fake rook takes DD eight and it's starting to look really dangerous for 04:05.140 --> 04:07.180 Black's king. 04:07.540 --> 04:12.730 So there are options here of playing after Queen Tense day. 04:14.980 --> 04:16.270 We can play queen. 04:16.270 --> 04:18.670 A full check picking up. 04:19.430 --> 04:19.940 Pardon me. 04:22.250 --> 04:23.450 Picking up the bishop. 04:23.450 --> 04:26.600 So this cheque picks out the bishop and so on. 04:27.830 --> 04:29.940 So that be a pretty strong indeed. 04:29.960 --> 04:38.000 So anyway, Queen takes five was played and we have Bishop DD three anyway and like square weaknesses 04:38.000 --> 04:46.340 are increased after H six here G six does fall victim again to a bishop sacked would be justified this 04:46.340 --> 04:55.040 position with Queen H six and here note H five looking at F six is exceptionally dangerous for blank. 04:55.940 --> 05:04.130 So st f five Queen g six check here nice f six and say Bishop C free trying to strengthen the diagonal 05:04.130 --> 05:11.420 Queen G eight Checking is something we could take on E eight And the thing is about this kind of position 05:11.420 --> 05:19.910 is we've accumulated so many pawns that actually we can consider this a success with Rook against two 05:19.910 --> 05:21.740 bishops, but so many pawns. 05:21.740 --> 05:23.240 It's just a winning position. 05:23.240 --> 05:28.670 Basically, the pawns are going to be too much, and this bishop's not very good on B7, to say the 05:28.670 --> 05:29.180 least. 05:29.180 --> 05:36.680 So H six was tried, but now Bishop is making very comfortable looking bishop on the nine squares. 05:36.680 --> 05:40.700 We have rook f five and now the knights online squares. 05:40.850 --> 05:45.470 So most of white's pieces are on white squares apart from rook on a one we have c five. 05:46.100 --> 05:49.410 If a five we can play knight H for this. 05:49.520 --> 05:53.240 I just wanted to demonstrate what we can do with Knight H four with a five. 05:53.240 --> 05:57.680 It's not a particularly good idea, but let's say this position we have Bishop H seven check. 05:58.040 --> 06:03.860 And you can see here that if King H eight we have 96 check and then pick up the Queen will check. 06:04.130 --> 06:08.330 And the thing is, if King of seven, Queen G six, check this position. 06:08.900 --> 06:09.680 Queen Thanks. 06:09.680 --> 06:17.420 G seven We have now bishop at five on the cards and if f five we can play queen takes B seven with a 06:17.420 --> 06:18.410 big advantage. 06:18.860 --> 06:21.380 So yeah, very dangerous scenarios are emerging. 06:21.380 --> 06:23.940 We have C five being played eight times. 06:23.990 --> 06:27.710 B five here again, 984 is strong. 06:27.710 --> 06:29.270 That's a strong idea as well. 06:29.270 --> 06:32.900 This position, Bishop H seven Shank and G three for moments. 06:33.170 --> 06:35.300 So there's no issue with G two. 06:35.300 --> 06:41.660 We can have some delay gratification here before the attack and now with 96 check, we're just going 06:41.660 --> 06:47.720 to be winning material without being mated on G two in any case, you know, so that's good. 06:47.900 --> 06:50.570 King G 896 No problem. 06:50.570 --> 06:57.770 So anyway, eight takes B five, though as good as well for Rook seven it's such a strong position we 06:57.770 --> 07:03.830 can echo H four hair Queen g5g3 Again, this is going to be a super strong possession. 07:04.370 --> 07:13.370 For example, queen sized one hair C four, queen DD seven and here Queen D five check, 9g6 check. 07:13.370 --> 07:15.260 And we're just winning tons of material. 07:15.260 --> 07:15.980 Ouch. 07:15.980 --> 07:18.320 So anyway, Rook seven is also good. 07:18.320 --> 07:23.150 Queen C seven Knight H four Now pair of rooks come off. 07:23.150 --> 07:28.820 Queen takes the one Rook eight But now an absolutely brilliant move in this position so Karpov aware 07:28.820 --> 07:36.320 tactically he's got a big positional advantages and there's a beautiful crowning of the tactics crowning 07:36.320 --> 07:42.290 with tactics in combination now so in this position what would you play for 100 points. 07:42.380 --> 07:43.580 Beautiful stuff. 07:47.220 --> 07:47.760 Yeah. 07:50.100 --> 07:57.900 Lovely Queen G for bypassing the bishop's control on diagonal looking at e sex and to make the king 07:58.470 --> 07:59.760 basically queen. 07:59.940 --> 08:05.940 Sex is played just to show if Rook takes a seven Queenie six check and if King of eight we have Queenie 08:05.940 --> 08:11.370 eight mating mate if king again, the back row is weak were mating. 08:12.450 --> 08:14.250 So Queen C six is tried. 08:14.250 --> 08:16.650 But now guess what is played Hare. 08:19.510 --> 08:23.410 No one is confident in the LightSquared strategy. 08:23.410 --> 08:29.560 Paying off how tactically Rook tanks B seven Getting rid of Black's nine Square defender Queen takes 08:29.560 --> 08:29.920 B seven. 08:29.920 --> 08:31.540 Getting access to E six. 08:32.230 --> 08:33.790 So King eight is played. 08:33.790 --> 08:40.450 If King F eight, there's actually Bishop H five vacating G six for G six mating. 08:40.780 --> 08:44.830 And here, for example, Queen takes F six, Jack, Queen and seven. 08:44.830 --> 08:46.540 We can play nine, takes G six check. 08:46.540 --> 08:48.440 And here there's Queen Checkmate. 08:49.540 --> 08:55.060 And if King E eight, then we can play check, for example, and just pick up the rook and carry on. 08:55.630 --> 08:56.800 So that'll be great as well. 08:56.800 --> 09:02.560 So King H eight is tried, but now Bishop E four with tempo and Black resigned. 09:02.770 --> 09:05.290 Let's have a look at this final possession. 09:06.430 --> 09:11.950 So first of all, the work really doesn't want to leave the back row, otherwise there'll be introducing 09:11.950 --> 09:12.430 Queenie. 09:12.640 --> 09:17.860 So let's say Quincy seven we can play 9g6 check. 09:17.860 --> 09:24.220 And here just take on a simple and here, although it seems to be. 09:24.220 --> 09:24.550 Hold on. 09:24.550 --> 09:26.860 We've just lost our material advantage. 09:26.860 --> 09:27.850 We're mating, basically. 09:27.850 --> 09:29.210 Bishop E four check. 09:29.560 --> 09:30.490 King G five. 09:30.520 --> 09:32.080 Queen G for is checkmate. 09:32.170 --> 09:35.170 So that's a beautiful line, but there's some others as well. 09:35.440 --> 09:39.490 So Queen a seven, We have 9g6 tracking H seven. 09:39.490 --> 09:45.940 And we can play the quiet king H to preventative move for any naughty business with Queen A one with 09:45.940 --> 09:49.210 check and then Queen E five when our knight's not looking at E five. 09:49.210 --> 09:53.140 This is such a strong move here and. 09:55.640 --> 09:57.920 Let me show you why King is such strong. 09:58.070 --> 10:04.040 Say 97, Shaq and Queen are five looking to make on age seven, but Black has the two. 10:04.040 --> 10:06.710 Check the fence, which is annoying. 10:06.710 --> 10:08.300 We're still winning, but it's annoying. 10:08.300 --> 10:12.650 So actually we can even do better with King H two and say Check. 10:12.650 --> 10:19.970 We can play our four ruling out Black's use of the E five square and now we play 97 check without any 10:19.970 --> 10:21.460 sort of counterplay at all. 10:21.470 --> 10:25.430 Queen at five looking at H seven Queen J We just contain the Queen. 10:25.670 --> 10:27.050 So yes, that's beautiful. 10:27.050 --> 10:34.490 Queen A sex is another option, but we have G six checking H 795 Check this double check. 10:34.730 --> 10:36.950 King H ain't fg6. 10:36.950 --> 10:42.410 We just may ensure order with Queen F seven checking age 90 6g6 is mine. 10:42.620 --> 10:49.400 So here on page eight we have seven check King G and now nine states H six double check. 10:49.400 --> 10:50.780 So the king has to move. 10:51.950 --> 10:52.970 And now? 10:52.970 --> 10:53.860 Yes, guess what? 10:53.870 --> 10:54.470 For ten points. 10:54.470 --> 10:55.610 What would you play here? 10:57.290 --> 10:57.740 Yeah. 10:57.830 --> 11:02.480 Queen g h So if the rook takes G, eight of seven is checkmate. 11:03.020 --> 11:03.840 Wow. 11:03.890 --> 11:09.910 A beautiful variations in the end, but we don't see them visually for sure. 11:09.910 --> 11:13.160 He understands quite clearly his position is busted. 11:14.270 --> 11:14.700 Yeah. 11:15.710 --> 11:23.030 So it's amazing how the accumulation of a few light square weaknesses leads to such devastations. 11:23.030 --> 11:26.840 But how many players would consider Bishop takes E five. 11:26.840 --> 11:28.280 For me, this is instrumental. 11:28.280 --> 11:34.300 If you look at neural network games sometimes to amplify a light square color complex weakness. 11:34.300 --> 11:40.130 So a set of light squares, sometimes we need to give up the bishop opposite to the color complex we 11:40.130 --> 11:47.240 want to have an advantage on and we see that this bishop, you know, is really not that relevant after. 11:47.240 --> 11:53.000 So this Square campaign is really great with this bishop as a bystander on the other side of the road, 11:53.000 --> 11:53.960 so to speak. 11:54.170 --> 11:59.540 We speak of a road as light squares and dark squares on the other side of the road, and a lot of White's 11:59.540 --> 12:05.780 moves converge for the beautiful final light square attack, taking out B seven. 12:05.780 --> 12:06.980 It's beautiful stuff, really. 12:06.980 --> 12:08.000 It's poetry. 12:08.180 --> 12:11.270 I really hope you enjoyed this game as much as me. 12:11.600 --> 12:14.750 Karpov at his best and so much.
