WEBVTT 00:01.190 --> 00:02.090 Hi there. 00:02.120 --> 00:08.120 In this lecture, we see one of the most amazing games of the 1963 Botvinnik Petrosian World Championship 00:08.120 --> 00:08.610 match. 00:08.630 --> 00:10.460 This is in round five. 00:10.460 --> 00:13.970 Take and Petrosian plays C for the English opening. 00:13.970 --> 00:19.130 We have G six DD 496 and we transpose into a Grunfeld defense. 00:19.130 --> 00:27.080 We have knights have three from Tigran Petrosian Botvinnik plays Bishop g7e free black consoles Bishop 00:27.080 --> 00:30.410 E to d c for Bishop C four. 00:30.440 --> 00:31.370 C five. 00:31.910 --> 00:34.580 D five, e six. 00:34.610 --> 00:41.930 Now there's a tiny bit of controversy here with e six after D takes e six White does have. 00:42.780 --> 00:49.470 A small advantage in terms of Black's pawn structure has been slightly compromised. 00:49.710 --> 00:52.320 There's an extra pawn islands here. 00:53.070 --> 00:55.800 There's three pawn islands in the black possession. 00:55.800 --> 01:05.760 And in fact, one of the things which we can potentially exploit about this is that E5 is not so exposed 01:05.760 --> 01:07.530 from a frontal attack. 01:07.800 --> 01:17.340 So bear that in mind, we have King E2 96 and this means basically both E five and E four. 01:17.370 --> 01:24.630 These squares might be useful for white, more useful than usual to set up camp without being disturbed. 01:25.080 --> 01:32.310 So we have rook D1 rook 88 and Petrosian doesn't mind the exchange of rooks here like g five rookie 01:32.310 --> 01:33.480 and our knight ge4. 01:33.510 --> 01:38.820 You can see that this is a very comfortable knight hitting C five and is not exposed on the e-file. 01:39.630 --> 01:42.360 So it's less assignable. 01:42.360 --> 01:50.070 L And when we say salable, less prone to attack, more comfortable there and. 01:51.780 --> 01:52.860 Yeah, it's just. 01:52.860 --> 01:54.060 It's just a very nice noise. 01:54.090 --> 01:55.560 But is this enough to win the game? 01:55.740 --> 02:01.800 We see B six rook B won, which releases the possibility of playing the B pawn on pending. 02:01.800 --> 02:05.220 The B pawn might be four and then Bishop D two. 02:05.340 --> 02:06.590 We have 95. 02:06.600 --> 02:10.380 If Knight takes a two, this backfires with Rook one. 02:10.800 --> 02:17.520 This position White can take on B four, then take on a seven and it doesn't matter about B two. 02:17.520 --> 02:19.080 Dropping off to B seven. 02:19.080 --> 02:21.570 Y is going to be better here. 02:21.570 --> 02:24.870 For example, this position is better for white. 02:24.870 --> 02:31.650 So 95 we have a four and this restrains Black's queenside pawn majority. 02:31.650 --> 02:36.930 You can argue, well, black's got this queenside pawn majority free to two That's restrains though 02:37.260 --> 02:42.570 rook now b four and this is away from the glare of the bishop putting pawns on light squares on the 02:42.570 --> 02:43.500 other side of the road. 02:43.500 --> 02:47.580 So, so to speak to the bishop is a good safety point. 02:48.810 --> 02:50.400 On the nine squares, Bishop feint. 02:52.600 --> 02:59.770 What else if si for the thing is why it has 96 -- the rook and pawn. 03:00.910 --> 03:03.660 And yeah, there's no backfire here. 03:03.670 --> 03:04.660 This is just winning a pawn. 03:04.660 --> 03:04.870 So. 03:04.870 --> 03:10.420 Bishop F eight, Rook C one, Bishop E seven and now be four. 03:10.630 --> 03:11.680 We have c four. 03:11.680 --> 03:14.830 And this is becoming a bit of a vulnerable pawn after B five. 03:14.830 --> 03:18.160 It's kind of disconnected from Black's other pawns. 03:18.400 --> 03:19.630 King of seven. 03:21.070 --> 03:24.880 So here, if Bishop Are you free? 03:25.210 --> 03:27.370 Roxy To C free. 03:29.090 --> 03:32.630 And one can play Bishop, S.C. free here. 03:33.740 --> 03:41.780 So, for example, this position as King DD two and taking on B four, it ends up being an edge for 03:41.780 --> 03:42.130 white. 03:42.140 --> 03:48.680 This position is an edge for White's safety point. 03:48.710 --> 03:51.170 Tactically, if we enter this variation. 03:52.260 --> 03:52.980 On scifri. 03:52.980 --> 04:00.520 If he takes scifri, then that's announced night before and that's winning material. 04:00.540 --> 04:02.850 The is looking at C one. 04:02.850 --> 04:03.940 So that would be a bad idea. 04:03.960 --> 04:06.390 So Bishop takes scifri though is a small entry point. 04:07.020 --> 04:10.110 We have though in the game. 04:10.860 --> 04:16.540 We have seven sort of bishops, eight free bishops. 04:16.560 --> 04:16.800 See? 04:16.800 --> 04:19.110 Free Bishop, a free hand. 04:20.200 --> 04:21.640 And now Roxy, too. 04:22.270 --> 04:27.760 So with the pool firmly blockaded these active possibilities that we just saw in that generation, they 04:27.760 --> 04:30.310 don't exist now. 04:30.970 --> 04:37.470 So, yes, you know, that's the value of blockade prevention with strong prevention is blockade. 04:37.480 --> 04:38.740 It's the ultimate blockade. 04:38.740 --> 04:40.870 We don't see that see free stuff. 04:41.560 --> 04:43.210 So we see black plane night. 04:43.240 --> 04:45.520 Take free check here. 04:47.930 --> 04:57.230 If instead Bishop E 782 If we have a look at this position for a moment, we can win C four And even 04:57.230 --> 05:03.980 if black gets the A pawn back, this end game is kind of favorable for white. 05:03.980 --> 05:09.500 One pawn is stopping two, which is a kind of Capablanca end game rule one, pawn locking two. 05:09.890 --> 05:15.800 And yeah, we're just going to be better here because that be pawns vulnerable. 05:15.980 --> 05:20.840 And this is just one example where we can end up winning the people with advantage. 05:21.410 --> 05:31.490 So we have nine take C free check rook C for bishop B for Rook goes back to C two king E 792 teasing 05:31.490 --> 05:34.580 the pawn forward with C free. 05:35.750 --> 05:38.890 It looks like a bad idea to take on the two. 05:38.900 --> 05:44.990 The king could come and be very comfortable on C for an end to be for with this pawn really looking 05:44.990 --> 05:45.830 vulnerable. 05:46.280 --> 05:53.570 So we have C 394 and this represents. 05:54.900 --> 06:00.570 Basically blank playing now a -- site with the track the way it's played. 06:00.780 --> 06:06.150 Because if check now King B for this -- is going to go so the opportunity is taken to invade with 06:06.150 --> 06:08.330 the rook and the cost of that --. 06:08.340 --> 06:09.570 Is it enough? 06:10.370 --> 06:12.050 Bottleneck to play like this. 06:12.410 --> 06:21.050 We have Rook age one and 94, offering H two up for positional advantage if h three The thing is, Bishop 06:21.050 --> 06:23.630 takes C free king. 06:23.660 --> 06:27.230 Take C free rook D one though. 06:27.230 --> 06:27.470 Yeah. 06:27.470 --> 06:35.530 This is still plausible for white with advantage, but it's interesting to keep the knights on so 94. 06:35.540 --> 06:40.220 It's interesting to keep this note on because it's very difficult for Black to get to this night and 06:40.220 --> 06:41.390 it's very nice and central. 06:41.390 --> 06:49.250 So offering H to King default, there is a particular idea here of being very, very aggressive with 06:49.250 --> 06:52.070 the rook, the knight and the king. 06:52.070 --> 06:59.810 So offering even G2 King D seven's played if rook takes G to rook C seven Shaq and actually we can take 06:59.810 --> 07:00.950 our H seven. 07:01.580 --> 07:05.710 And this position is absolutely great for white here. 07:05.720 --> 07:10.310 For example, the king can infiltrate a bit more and these pawns are vulnerable. 07:10.310 --> 07:13.010 So for example, King takes e six with advantage. 07:13.190 --> 07:20.840 So King D seven was played g free bishop before and now the king goes forward. 07:20.840 --> 07:22.070 King E5 Very aggressive. 07:22.070 --> 07:24.140 King rook H five check. 07:24.890 --> 07:27.260 And now king of six, you might ask. 07:27.260 --> 07:28.430 Hold on, hold on. 07:28.910 --> 07:35.810 What if black hair had tried to prevent King F six with Bishop E seven? 07:35.810 --> 07:39.500 The thing is rook D to check and then we're just taking on E six. 07:40.010 --> 07:41.300 Yeah, it wasn't possible. 07:41.300 --> 07:41.540 So. 07:41.540 --> 07:42.530 Rook five check. 07:42.530 --> 07:46.220 The king goes to F six, Bishop E seven check. 07:47.750 --> 07:56.090 If Rook had five instead, check this position of the G four rook C for the king's really a fighting 07:56.090 --> 07:59.480 piece and is going to be winning one of these pawns. 08:00.860 --> 08:06.980 So yeah, it's looking very dangerous for black hair. 08:09.280 --> 08:16.420 And, you know, there's also possibilities of playing F4 and G five, if appropriate as well. 08:16.420 --> 08:22.780 So we have Bishop E seven check though, King G seven, E five. 08:22.780 --> 08:27.490 If instead of E five, let's say Rock H one is played. 08:27.490 --> 08:32.670 King F seven has a strong threat of Brook RD to check and then winning the bishop. 08:32.680 --> 08:37.090 So let's say rook d one to prevent rook d to check. 08:37.540 --> 08:45.100 We can still make inroads here with white with C six and if e five we can actually play rocky sex and 08:45.100 --> 08:46.870 the bishop moves g four. 08:46.900 --> 08:49.360 Let's take this example with G five. 08:50.140 --> 08:52.100 We have advantage here with white. 08:52.120 --> 08:52.810 It's very nice. 08:52.810 --> 08:55.210 This endgame advantage persists. 08:55.210 --> 09:02.360 So say check King G eight rookie seven rook C6 Look at that Knights in front of the E five pawn. 09:02.380 --> 09:05.100 It's a brilliant position for the knight. 09:06.160 --> 09:09.670 9f6 And we're trying to win material as well. 09:10.540 --> 09:17.170 We can even give up F two and once we take on H seven, G six is going to drop and we're on the way 09:17.170 --> 09:18.150 to winning here. 09:18.160 --> 09:22.300 So that's just one example of Rook h1y here. 09:22.330 --> 09:24.970 King of seven is so dangerous for Rook D to check. 09:25.690 --> 09:29.420 So E five was tried immediately. 09:29.440 --> 09:33.040 We have rook 6h1 and now king of seven. 09:34.480 --> 09:36.790 Not the illegal move. 09:36.790 --> 09:38.580 This is a skilled move. 09:38.590 --> 09:45.010 Botvinnik was trying to suggest an illegal sealed move had been written which would have lose white 09:45.010 --> 09:45.850 the game. 09:46.810 --> 09:49.690 But Botvinnik was trying to claim that quite desperately. 09:49.690 --> 09:52.690 It seems to try and win by forfeit. 09:53.110 --> 09:59.050 But Petrosian had a peculiar way of writing the number seven with tails. 09:59.200 --> 10:05.380 So he actually meant, you know, clearly meant based on his past handwriting. 10:05.380 --> 10:06.430 King of seven. 10:06.430 --> 10:07.900 So a king of seven. 10:09.550 --> 10:17.810 Now here we have Rook one rookie six, prompting the bishop to move to D eight. 10:17.830 --> 10:21.640 If Bishop B four The thing is, there's nine of six. 10:21.640 --> 10:24.430 Check, rookie eight check. 10:24.940 --> 10:30.580 And this possession If we saw a four for seven, this is just better for white. 10:30.620 --> 10:34.780 White's getting a number of past pawns over here. 10:35.140 --> 10:43.330 And for example, with 94 White's going to win this pawn race this past g pawn is very strong for example 10:43.330 --> 10:43.780 here. 10:44.470 --> 10:50.230 And you can see that this is going to be winning as an example. 10:51.040 --> 10:55.270 So Bishop Dines is tried trying to avoid this. 10:55.840 --> 10:56.920 Six Check. 10:57.040 --> 10:58.420 Rook RD six check. 10:58.420 --> 11:00.370 Kinsey King E eight. 11:00.400 --> 11:01.810 The bishop is being harassed. 11:01.810 --> 11:03.100 Rook six. 11:03.640 --> 11:04.810 Rook rd one. 11:05.680 --> 11:11.230 If rook takes a four here, there's no C free with tempo for 95. 11:11.350 --> 11:13.660 So Rook five, 95. 11:13.900 --> 11:19.300 And then we're playing rook C seven, check and E four. 11:19.300 --> 11:22.480 And this is sufficient if rook for winning. 11:22.480 --> 11:30.760 If rook takes the thing is this position King E seven and that powerful D pawn past pawn is winning. 11:30.760 --> 11:33.810 It's got the express route train with tempos. 11:33.820 --> 11:37.090 So rugby one is tried. 11:38.430 --> 11:48.240 We have g5d checking f7d7, checking King G eight and it moved 48 bubbling, resigned. 11:48.510 --> 11:53.610 So if h five let's take H five then Rook takes g six. 11:53.610 --> 11:55.650 And this is just great for white. 11:56.310 --> 11:57.000 Yeah. 11:57.390 --> 12:00.720 Pawns are dropping off and we can even secure a four there. 12:01.350 --> 12:02.970 And we're just winning pawns. 12:03.390 --> 12:04.170 Winning. 12:04.440 --> 12:07.950 And if h six, we can play 96. 12:07.950 --> 12:14.760 And actually here we can simply just simplify and use the Capablanca rule one, pawn locking two. 12:15.180 --> 12:19.710 We're going to pick up these pawns with a winning position, easily winning king and pawn ending. 12:20.190 --> 12:27.180 So, yes, a really fantastic game in this world championship match full of drama. 12:27.960 --> 12:32.730 And that King invasion was very, very interesting. 12:33.630 --> 12:36.120 So very, very interesting game with the King invasion. 12:36.120 --> 12:41.970 The King aggressive king in endgames is a beauty to behold quite often. 12:42.270 --> 12:47.460 So like this game, but also the knight versus bishop, the knight superiority versus the bishop and 12:47.460 --> 12:48.660 this pawn islands. 12:48.660 --> 12:51.240 We can see this is a vivid example. 12:51.240 --> 12:56.670 While we say that sometimes the number of pawn islands, if there's pawn islands, that could represent 12:56.670 --> 12:58.320 an exploitable weakness. 12:58.350 --> 13:05.040 If there's nice blockades in front of single pawn islands, isolated pawns, basically, then they are 13:05.040 --> 13:11.430 great squares where we're covered, where naturally we naturally have protection for not only from fronts 13:11.430 --> 13:12.870 or pressures. 13:12.960 --> 13:18.890 So yeah, great use of the knight in this game as well as the king and the invasive rook. 13:18.900 --> 13:25.170 So I hope you enjoyed this beautiful end game, a very important game in chess history in this 1963 13:25.170 --> 13:29.010 world Championship match with great endgame. 13:29.010 --> 13:34.770 Lessons in game, strategy and game possession will play beautiful stuff and so much.
