WEBVTT 00:00.930 --> 00:01.720 Hi there. 00:01.740 --> 00:06.330 In this lecture, we see one of my all time favorite games of token Petrosian. 00:06.330 --> 00:07.560 He's playing against Ludic. 00:07.560 --> 00:12.540 PASHMAN, who is a great grandmaster and great book author. 00:12.540 --> 00:14.700 Actually, I have one of his books on the middle game. 00:14.700 --> 00:21.420 So this was played in 1961, The Bled Tournament, Round Six Knights and Free from Tigran Petrosian. 00:21.420 --> 00:25.710 We have C five, G free C six, Bishop G two. 00:25.710 --> 00:33.330 So this is an opening hassle free idea just to play the King's engine attack system with the white pieces. 00:33.330 --> 00:35.820 So g six Chosen castles. 00:35.820 --> 00:39.720 Bishop g7d3e6e4. 00:39.720 --> 00:41.760 I do have a course on the King's engine attack. 00:41.760 --> 00:46.680 By the way, if you want to play this set up, it's not very, very intensive. 00:46.890 --> 00:55.620 We have Knight G seven, Rookie one So this is a standard set up black castles and now E five is played. 00:55.620 --> 01:01.560 So this is interesting establishing this foothold which can be undermined, but at what cost we see 01:01.590 --> 01:04.800 D six So what is the cost of doing? 01:04.800 --> 01:07.680 D six Well, Petrosian actually takes on D six. 01:08.040 --> 01:14.280 We have Queen takes these six and now Knight BD two and it looks as though, well, there's nice ideas 01:14.280 --> 01:20.820 already for white, including Knight C and maybe a foreign bishop at four and get a grip on the E five 01:20.820 --> 01:21.530 square. 01:21.540 --> 01:29.280 So releasing the central occupation for control is a hyper modern idea, and it looks as though, you 01:29.280 --> 01:33.540 know, White's position is super solid here already. 01:33.540 --> 01:42.840 It's got that feel to it as still metal, very strong, steely look to the position in my view, very 01:42.840 --> 01:43.520 solid. 01:43.530 --> 01:52.380 We see Queen C seven might be free and already a mistake Knightly form so Black's possession does have. 01:52.590 --> 01:59.070 There are some positional issues the development lag here the bishop on C eight is not as good as the 01:59.070 --> 02:00.300 G two bishop. 02:00.810 --> 02:09.090 Instead if b six this tries to address the c a issue and if Bishop F for this position with C three, 02:09.660 --> 02:12.480 we can see that black should be okay. 02:12.480 --> 02:15.150 Even if D four is play, try and open up things. 02:15.840 --> 02:22.920 Black has resources like Quincy eight and if black gets to simplify like this, black should be absolutely 02:22.920 --> 02:23.730 fine. 02:23.940 --> 02:28.050 So that does seem as an example that seems plausible. 02:28.320 --> 02:31.770 And if D four immediately C takes even this position. 02:32.670 --> 02:35.430 Bishop B seven it's just even. 02:35.430 --> 02:43.260 But with 94, we have this important tempo gainer which increases y its control over key central squares 02:43.260 --> 02:46.530 like e five and the extended center square. 02:46.530 --> 02:52.320 You know, we can think of the classical central four squares, but there's also a kind of extended 02:52.320 --> 02:53.880 center around that. 02:54.540 --> 02:57.540 These squares are also interesting to think about. 02:57.540 --> 03:03.000 In the extended center we have Queen B six being played. 03:04.520 --> 03:06.950 So blacks holding on to C five if queenly. 03:07.130 --> 03:07.320 Yeah. 03:07.370 --> 03:10.020 White can consider taking on C five. 03:10.040 --> 03:16.160 There isn't really a meaningful backfire of the bishop takes her free bishop takes B to the thing is 03:16.160 --> 03:22.430 rook be one and look at all of these pieces pointed at B seven and let's say Bishop C free nine takes 03:22.460 --> 03:23.810 B seven with ten pawn. 03:23.810 --> 03:30.980 The Queen Bishop takes B seven, Bishop takes B seven, Bishop takes e, one queen takes e, one rook 03:30.980 --> 03:31.790 B eight. 03:31.820 --> 03:36.110 Y ends up being better here of the bishop e four. 03:36.500 --> 03:42.410 And if Knight takes every instead first, check this position with Queen B six. 03:42.860 --> 03:47.990 We've got Bishop E five and we're weakening the opponent's king hair. 03:48.020 --> 03:51.290 This is a very pleasant position indeed for white. 03:51.470 --> 04:00.860 We can see that we've swapped central occupation for central control and C five is a liability for black 04:00.860 --> 04:02.000 to drop off at some point. 04:02.000 --> 04:03.800 Like this example. 04:03.800 --> 04:04.280 But why? 04:04.280 --> 04:06.350 It's going to be significantly better. 04:06.950 --> 04:12.020 And even if the free drops, why it's got the bishop, her hair and strong pressure and potential to 04:12.020 --> 04:13.550 create an outside pass pawn. 04:13.670 --> 04:14.930 So that's better for white. 04:14.990 --> 04:20.600 So we see Queen B sinks a number of F and now 95. 04:20.600 --> 04:24.230 This is a very powerful move to try and harass the Queen. 04:24.230 --> 04:28.220 With 9c4, we have nine takes B free and now for 100 points. 04:28.220 --> 04:29.630 What would you play here? 04:34.000 --> 04:37.540 Very important move to avoid simplification on this occasion. 04:38.020 --> 04:46.960 For if a tax be free, black could play Bishop takes e five, even though that does seem counterintuitive 04:46.960 --> 04:48.580 to weaken one's own king. 04:48.760 --> 04:54.670 But this position with F6 White's advantage is more limited than in the game continuation. 04:54.970 --> 05:00.850 And let's say Black doesn't play Bishop takes E5 apart Queen de A then once going to have a small edge 05:00.850 --> 05:01.480 here. 05:01.750 --> 05:04.570 This position black does have resources. 05:04.570 --> 05:06.010 Sure like this. 05:06.010 --> 05:08.290 So that hits the bishop on D six. 05:08.500 --> 05:17.680 And White's advantage is limited, but with C four very important tempo gainer hitting the Queen this 05:17.680 --> 05:18.370 position. 05:18.370 --> 05:21.280 White's got a lot of central control here. 05:21.520 --> 05:24.430 You see that there's nothing in the sense occupying center. 05:24.430 --> 05:31.180 But look at White's glorious bishops stretching all across through the central four squares is a really 05:31.180 --> 05:33.250 glorious position to look at. 05:34.330 --> 05:41.230 And threats include Rook five supported by the Knights looking at C five. 05:42.250 --> 05:48.370 And also Bishop de six looking at the skewer in the Knight and Rook. 05:48.820 --> 05:54.160 So we see a five being played and that does quite create more weakness as that. 05:54.160 --> 05:54.950 B six. 05:54.970 --> 05:56.830 Bishop D six. 05:56.830 --> 05:58.240 Bishop F sinks. 05:59.440 --> 06:02.690 So this is a very difficult position indeed of rookie aides. 06:02.800 --> 06:09.170 This position, as example of Bishop E five is going to be better for white. 06:09.190 --> 06:12.300 White could pick up the A five pawn as one example. 06:12.310 --> 06:15.220 You can see that this pressure has conspired here. 06:15.220 --> 06:20.760 The bishop pinning b seven said pressure conspired on a five in this example. 06:20.770 --> 06:29.530 And if a four we can play bishops hg79 sage seven Queen f four is attractive and there are ideas here, 06:29.680 --> 06:31.600 very dangerous ideas. 06:32.080 --> 06:42.880 For example, 936 which would hit the Queen on B five and seven So if 98 let's say Queen E three now 06:43.900 --> 06:50.770 and yeah, we just have a magnificent position here, for example, where we're potentially winning 06:50.770 --> 06:51.340 material. 06:51.340 --> 06:55.000 So Bishop f six was tried, Queen F, King G seven. 06:55.000 --> 07:01.900 The king is not usually a good protector of things when the king is involved, but the thing is, what 07:01.900 --> 07:02.170 is black? 07:02.170 --> 07:02.710 Duke Bishop G. 07:02.710 --> 07:04.960 Seven We're just taking on E seven, Rookie eight. 07:04.960 --> 07:06.610 We're just playing Queen six. 07:06.610 --> 07:11.200 So it looks like an only move to play King G seven. 07:11.470 --> 07:20.350 Now Rookie four is played Rook D eight and now yeah, this is this is a bit of a mistake to say the 07:20.350 --> 07:20.670 least. 07:20.680 --> 07:22.180 Rookie a f knight. 07:23.290 --> 07:24.610 Defy, though. 07:24.610 --> 07:27.130 You know why it's just going to win material, right? 07:27.130 --> 07:28.600 That seems out of the question. 07:28.600 --> 07:30.100 So rugby ain't. 07:30.250 --> 07:36.970 Now, this next move is absolutely magnificent, showing the tactical teeth of Petrosian. 07:38.200 --> 07:42.580 So as many have said, you know, Trojans tactical abilities are absolutely amazing. 07:42.580 --> 07:49.690 Some people argue on par with Mikhail Tal, but he usually uses them only when there's very low risks 07:49.690 --> 07:50.020 to do. 07:50.020 --> 07:52.720 You know, tactics and combinations is very, very low risk. 07:52.720 --> 07:56.200 Petrosian hates losing, basically doesn't like speculation. 07:56.230 --> 08:01.600 He sees chess as a ruthless logic game where gambling shouldn't be part of it. 08:02.560 --> 08:04.950 If he wants to gamble, he could play backgammon instead. 08:04.960 --> 08:10.650 So anyway, there's a move here which is absolutely beautiful, which even Fischer admired. 08:10.660 --> 08:14.170 It's actually forcing a checkmate. 08:14.170 --> 08:18.730 It's a really beautiful move indeed. 08:19.000 --> 08:22.750 One of the most beautiful of all time, in my view. 08:22.750 --> 08:27.340 So for 500 points, what would you play and what is the idea behind it? 08:28.600 --> 08:29.920 What is the follow up? 08:29.920 --> 08:34.450 If you don't have the follow up, then you're just guessing the first movie. 08:34.450 --> 08:39.160 You need to know the follow up and the follow up is magnificent in its own right. 08:39.700 --> 08:45.820 So the first move is Queen takes F six check and now E five check. 08:46.120 --> 08:50.200 And now the beautiful move which ends the game. 08:52.980 --> 08:54.390 And that is Bishop G7. 08:54.390 --> 08:58.430 It stops the king from going back to safety and ends the game. 08:58.440 --> 09:00.820 Fisher described it as a real problem move. 09:00.840 --> 09:02.460 So here Black has to resign. 09:02.460 --> 09:04.560 Black resigned if f six. 09:04.860 --> 09:06.270 Let's take some examples. 09:06.300 --> 09:06.780 H four. 09:06.780 --> 09:07.430 Check. 09:07.440 --> 09:08.310 King H five. 09:08.340 --> 09:11.100 Bishop three is checkmate. 09:11.370 --> 09:15.390 So that's F six rule out if f5h4. 09:15.390 --> 09:20.450 Checking h five Bishop F three is not much different If Rook takes the free we're taking here. 09:20.460 --> 09:25.410 Okay, first and then we're playing h four check and then Bishop F three. 09:26.460 --> 09:32.340 And let's say the king went to, you know, instead of the king moving nine, 6h4. 09:32.340 --> 09:36.210 We're playing G takes h four check and F king of five. 09:36.210 --> 09:42.090 We have 96 checkmate or F King H five. 09:42.120 --> 09:45.600 Again we have Bishop F three. 09:46.740 --> 09:53.670 Champ means that Bishop is controlling this great squares on G seven If knights have 5h4 check nine 09:53.670 --> 09:55.950 takes g takes h4k5. 09:55.950 --> 09:56.850 We have Bishop H three. 09:56.850 --> 09:57.750 Checkmate. 09:58.260 --> 10:00.330 All 93 Checkmate. 10:01.410 --> 10:01.860 Yeah. 10:01.860 --> 10:03.780 If King H five, Bishop free. 10:03.780 --> 10:04.470 King G five. 10:04.470 --> 10:09.990 We have H four check King of five and now G four is checkmate. 10:10.950 --> 10:13.500 And the thing is, after H four check. 10:13.800 --> 10:18.900 There's also, by the way, instead of h four check, there's rookie five check nine to have five and 10:18.900 --> 10:22.050 now h four check with the knight taking in this game square. 10:22.260 --> 10:23.910 So it's all mating. 10:23.910 --> 10:24.300 Basically. 10:24.300 --> 10:24.960 It's a force. 10:24.960 --> 10:25.530 Checkmate. 10:25.530 --> 10:27.660 Really beautiful stuff. 10:27.870 --> 10:30.240 So Bishop G seven, ending the game here. 10:30.240 --> 10:34.950 This is a magnificence crowning of the earlier positional play. 10:35.130 --> 10:39.390 So we're interested in this particular course in the positional ingredients. 10:39.390 --> 10:50.130 We could say there was a kind of hyper modern swapping of central occupation here with E five to kind 10:50.130 --> 10:58.410 of get pieces, glancing through, peering through the sensor when the pawn was removed while its actual 10:58.410 --> 11:02.130 central grip did seem to be amplified here. 11:02.340 --> 11:10.800 So this strong central control over key squares leading to great things and with the bishop as an issue. 11:10.800 --> 11:15.810 So the positional play here leading up to the tactics is magnificent. 11:16.110 --> 11:23.520 This is a really reliable position for White to have with great tactical pressure and an absolutely 11:23.520 --> 11:25.440 beautiful, crowning combination. 11:25.440 --> 11:31.590 Now, to be fair, just to be accurate, rather, it could have been considered instead of rookie for 11:31.590 --> 11:36.000 I didn't want to spoil it for you first time round, but it's a rookie for it could have been played 11:36.000 --> 11:38.040 here as well. 11:38.280 --> 11:40.200 It could have actually been played here. 11:40.470 --> 11:46.290 And for example, this situation, the black king is in big trouble. 11:46.670 --> 11:51.030 You know, with G4, it's less clear than what happened in the game, though. 11:51.180 --> 11:55.350 So this situation is going to be mating the black King as well. 11:55.350 --> 12:01.290 But yeah, Rookie four was such a beautiful preload to what happened so that's more technical. 12:01.290 --> 12:07.530 Queen Text F six did actually exist a move earlier but yeah, after rook D eight that really smooths 12:07.530 --> 12:10.800 things out for queen size f six check even more. 12:11.130 --> 12:14.850 So I really hope you hope you enjoyed this iconic game. 12:14.850 --> 12:19.380 It's one of my favorite games of where I'm frozen of all time. 12:19.380 --> 12:20.250 Okay. 12:21.130 --> 12:21.880 I so much.
