WEBVTT 00:01.290 --> 00:02.130 Hi there. 00:02.250 --> 00:07.800 In this lecture, we see an absolutely iconic game, one of my favorite games of Tigran Petrosian. 00:08.190 --> 00:13.590 So this is against Boris Spassky in their 1966 World Championship match, Round ten. 00:14.040 --> 00:17.070 So take around Petrosian kicked off with nice and free. 00:17.520 --> 00:20.100 We have nine, we have six, G three, G six. 00:20.100 --> 00:24.360 So both sides V in Kettering, the bishops, the King's bishops. 00:24.930 --> 00:25.740 Now both sides. 00:25.740 --> 00:28.950 Castle, We have 96 knights C free. 00:28.950 --> 00:33.240 So this is a Kings engine defense for an ket operation. 00:33.570 --> 00:34.800 We have a six. 00:35.010 --> 00:38.370 DD 595. 00:38.370 --> 00:42.750 So this hits the c four pawn 92 and now C five. 00:42.750 --> 00:46.590 This is a standard way of trying to generate some counterplay with the black pieces. 00:46.890 --> 00:49.590 Queen C two We have E five. 00:50.820 --> 00:55.230 So now we have B free and on Knight G four. 00:55.620 --> 01:01.560 So Spassky is wanting to launch an attack on this side of the board with F five. 01:01.710 --> 01:08.300 We have E four, F five and now E takes F five, G takes F five. 01:08.310 --> 01:09.850 If Bishop takes a five. 01:09.870 --> 01:15.540 We get the E four square to play with, which can be very useful after Knight D four. 01:15.570 --> 01:21.360 That's a very nice kind of blockade which also hems in the G seven bishop. 01:22.050 --> 01:24.840 So this is positionally quite pleasant for Y. 01:24.840 --> 01:32.550 As example, this situation, even if we release the blockade, we can renew it with 94 later. 01:32.940 --> 01:38.160 And we're looking at the a five knight here with this bishop. 01:38.760 --> 01:39.600 If it goes back. 01:39.600 --> 01:39.780 Yeah. 01:39.780 --> 01:42.090 Once it's got a very comfortable position here. 01:42.780 --> 01:46.500 So basically g takes tries to keep e control. 01:46.500 --> 01:50.190 We have 90 1b5 and now F three. 01:50.190 --> 01:56.130 It looks as though White's pieces are a little bit passive on the first two rows here. 01:56.130 --> 01:58.530 So this move looks at the rock. 01:59.130 --> 02:05.490 We have Bishop B two, E takes our free bishop takes our free and our bishop takes B two. 02:07.040 --> 02:12.050 If we look around the squares, around the king, we're getting a vacuum here around the black king 02:12.500 --> 02:17.150 queen, thanks be to potential weaknesses which could be exploited later. 02:17.660 --> 02:25.610 95 the bishop goes to e to hear this safeguard C for we have that F for very aggressive, playful and 02:25.610 --> 02:27.590 Spassky even though he's weakened this king. 02:27.590 --> 02:36.170 So in effect, it is a bit like weakness, provocation in that an incentive has been given for black 02:36.170 --> 02:40.790 to create weaknesses around their KING So this is a kind of. 02:41.750 --> 02:47.270 You could say a position or strategy to encourage your opponent to go on the attack and to kind of burn 02:47.270 --> 02:55.100 the bridges, you know, make committal decisions like creating weaknesses We have now, G takes F four, 02:56.510 --> 03:01.550 it seems in this position, takes F or might have actually been technically more accurate. 03:01.550 --> 03:10.000 This position, for example, is going to be better for white. 03:10.010 --> 03:12.260 This situation is actually better for white. 03:12.950 --> 03:14.240 And we can take this a bit further. 03:14.240 --> 03:20.330 We can see the vacuum of weaknesses with nine of six on the cards or the queen being able to hit a five 03:20.330 --> 03:21.890 and go to G three later. 03:22.100 --> 03:28.130 This situation is rather pleasant and there's even tactics like 965 in this example variation hitting 03:28.130 --> 03:28.730 the queen. 03:28.730 --> 03:37.220 So there are danger points associated with Rook takes F4, but G takes F four was played. 03:37.490 --> 03:39.020 This leads to a very interesting game. 03:39.320 --> 03:43.700 H free and now a really interesting move. 03:43.700 --> 03:48.590 So black's guardian of the light squares is this Bishop? 03:48.590 --> 03:56.480 Guess what Abraham Petrosian plays here, which is really interesting for 100 points to try and expose 03:56.480 --> 04:04.040 further and connect to the existing weaknesses which have indirectly kind of been provoked by saying, 04:04.040 --> 04:06.260 Come and get my king, come and get my king. 04:06.500 --> 04:10.370 So what do you think the move is here that won't place? 04:12.860 --> 04:13.370 Yeah. 04:13.730 --> 04:14.570 93. 04:14.600 --> 04:15.950 Just offering an exchange. 04:16.700 --> 04:18.440 We have Bishop takes everyone. 04:19.400 --> 04:20.680 And this is actually a mistake. 04:20.690 --> 04:26.030 It gives a very dangerous position now for white winning the exchange here. 04:26.180 --> 04:31.580 If Rook takes F4 instead, this situation with Queen G five check. 04:31.580 --> 04:35.420 Bishop takes G for light and takes G for $0.09. 04:35.420 --> 04:39.100 G for Bishop G for Queen G for check. 04:39.290 --> 04:47.350 This situation should actually end up being about equal with best play for both sides. 04:47.360 --> 04:52.850 There's yeah, there's Waynes ways it means for this to maintain equality. 04:53.330 --> 04:59.240 This situation if rook takes a two check here the king gets active. 04:59.240 --> 05:03.740 There's enough compensation for both sides to work with to draw. 05:04.370 --> 05:09.290 And if rook g check again, you know this is going to be draw ish. 05:09.560 --> 05:14.630 So that would have been an interesting move to play. 05:14.630 --> 05:22.070 Rook takes our four here leveraging the idea of Queen G five check but with Bishop takes F one. 05:22.070 --> 05:28.990 This vacuum of weaknesses around the King is also potentially on the line squares as well. 05:29.000 --> 05:36.470 So we've got like square weaknesses as well as dark square weaknesses and they can help to really create 05:36.470 --> 05:38.450 dangers around the black king. 05:38.450 --> 05:43.580 We have 96 and our Bishop G four and already we have a bishop coming to e six. 05:43.820 --> 05:48.230 It seems exceptionally dangerous, but isn't there a technical issue and then it takes her four. 05:48.230 --> 05:56.030 Doesn't that stop any use of E six Guess what Tig controls in place air, which is absolutely brilliant 05:56.030 --> 05:57.170 for 100 points. 05:58.520 --> 05:58.940 Yes. 05:58.940 --> 06:00.250 It's just a technicality. 06:00.410 --> 06:01.100 It takes her four. 06:01.100 --> 06:04.280 It can be erased off the board with Rook, takes her four. 06:04.280 --> 06:07.430 So double exchange sex so far from white. 06:07.670 --> 06:09.860 And the rewards are rich, though. 06:10.070 --> 06:16.040 So already black has to go back with the rook and look at this vacuum of weaknesses. 06:16.040 --> 06:20.630 Now around the King, the knights are ready to pounce. 06:20.630 --> 06:22.730 94 is played. 06:22.730 --> 06:24.230 We have created four. 06:24.560 --> 06:33.500 If B takes C4, we can play 95 with menacing ideas and direct mate France on G seven here. 06:34.220 --> 06:36.740 So this is for example, mate. 06:37.640 --> 06:42.590 And yeah, it's just so dangerous if queen if I Queen F six. 06:42.590 --> 06:50.420 And the thing is here we can play Knight G five and six, F seven and Bishop takes F seven check and 06:50.630 --> 06:51.260 H six check. 06:51.260 --> 06:52.460 Everything is crumbling. 06:52.940 --> 07:00.050 So Queen H four is tried, but now it has the point to hit the Knights. 07:00.050 --> 07:03.530 We have Knight 66, Queen G five. 07:03.530 --> 07:07.760 Check and hear King H one is played. 07:08.510 --> 07:12.290 We have Rook 8a7 if queen takes a fray. 07:12.290 --> 07:19.400 The thing is, Bishop takes F seven check king for we have Queen H eight, check King seven and now 07:19.910 --> 07:21.710 Knight a five check. 07:22.310 --> 07:25.340 And this is kind of vicious. 07:27.620 --> 07:30.080 Our Queen's attacked her, but we're attacking the opponents queen. 07:30.080 --> 07:32.420 And here we can play Bishop E six check. 07:34.190 --> 07:39.350 And the thing is, we're grabbing a check to get our queen out of danger, and then we're going to take 07:39.350 --> 07:40.700 the opponent's queen next. 07:40.880 --> 07:45.140 So Rook eight, a seven, was tried, but now an absolutely beautiful finish. 07:45.620 --> 07:49.160 Can you spot the finishing combination for 200 points? 07:50.550 --> 07:51.960 Really beautiful stuff. 07:52.440 --> 07:53.820 It starts with. 07:54.480 --> 07:55.480 You might want to pause the video. 07:55.500 --> 07:58.470 It starts with Bishop, takes off some check. 07:58.470 --> 08:03.750 And here is one of the most magnificent Tiger Stadium tactical moves. 08:04.050 --> 08:05.850 In my view, one of my favorites. 08:05.850 --> 08:07.590 One of my absolute favorites. 08:08.340 --> 08:09.990 Very iconic game. 08:10.230 --> 08:14.770 So Tigran Petrosian, you know, they say he's like Tao in terms of tactical ability. 08:14.790 --> 08:19.290 Just usually, you know, he reserves his tactics for defense and not losing. 08:19.530 --> 08:26.060 But you know, we can see the magnificent tactical abilities of Tigran Petrosian with this next move. 08:26.070 --> 08:29.040 So check all checks, even the most outrageous ones. 08:29.280 --> 08:34.680 And hopefully you'll see that that vacuum of weaknesses is brutally exploited here. 08:35.470 --> 08:35.980 Yeah. 08:36.590 --> 08:39.160 Queen h h what a magnificent move. 08:39.160 --> 08:40.300 And it ends the game. 08:40.510 --> 08:48.970 If taking note takes F seven check, Why, It's just a whole piece up and also a pawn up. 08:48.970 --> 08:51.520 So this is absolutely a winning position. 08:51.730 --> 08:53.470 So, yeah, a beautiful game. 08:53.470 --> 08:59.350 It really is a striking game for weakness, provocations, you know, trying to encourage weaknesses 08:59.350 --> 09:05.170 from the opponent, giving them what seems to be a legitimate agenda to get to your king. 09:05.440 --> 09:12.580 But the fact is that they're creating weaknesses in the process and there were expertly exploited these 09:12.580 --> 09:17.410 weaknesses through two key exchange sacrifices. 09:17.620 --> 09:22.840 So one position the bishops gets assists and the other to make sure the bishops get into Essex. 09:22.840 --> 09:28.660 Once that bishop got to Essex, the Knights were really dangerous with the Queen around the weaknesses 09:28.660 --> 09:29.800 around the opponent's king. 09:29.800 --> 09:36.970 So really fascinating game for weakness, provocation, and saying, come and get me an amazing kind 09:36.970 --> 09:38.830 of counter-attack game. 09:38.830 --> 09:46.870 So counter-attacks are often really powerful when opponents have committed their pawns and created irreversible 09:46.870 --> 09:47.680 weaknesses. 09:47.710 --> 09:50.140 OC has so much.
