WEBVTT 00:00.810 --> 00:01.530 Hi there. 00:01.560 --> 00:04.230 In this lecture, we see a game of Tyrion Petrosian. 00:04.230 --> 00:10.050 And yes, I know he's known as more of a position on defensive player rather than an attacker, but 00:10.050 --> 00:16.830 they say the best form of defense is counterattack and we see a major counterattack here. 00:16.830 --> 00:19.890 So attack can be part of defense. 00:19.890 --> 00:28.860 And Petrosian was a fan of Aron Nimzowitsch and sometimes he likes strengthening his position and opponent's 00:28.860 --> 00:34.320 attacks when he is in a strong position, Sometimes they are likely to fell. 00:34.560 --> 00:38.520 So he's playing here against Boris Spassky, a great attacking player and world champion. 00:38.520 --> 00:42.420 So this is their world championship match Round ten in 1966. 00:42.600 --> 00:44.490 Nice have free from Tigran Petrosian. 00:44.490 --> 00:47.130 We have nice to have six from Boris Spassky. 00:47.130 --> 00:51.030 G Free g6c for Bishop G seven. 00:51.030 --> 00:54.720 We have a thing Kanto variation of the King's Indian defense. 00:54.960 --> 01:02.610 So we see 9c3d6d4a6d5 19 five So this is slightly provocative. 01:02.610 --> 01:05.520 It is a way of getting some counterplay. 01:05.730 --> 01:08.160 90 2c5 on the queenside. 01:08.490 --> 01:14.790 So we see Queen C two here and now Boris Spassky plays E5 closing the center. 01:14.790 --> 01:20.760 He's quite ambitious with this move, not relying on the traditional C for counterplay. 01:20.760 --> 01:23.280 He wants to have the sense of closure. 01:23.280 --> 01:28.770 He can play like a king's engine pawn storm stall if he played Rook B ain't. 01:28.800 --> 01:33.720 There are issues that white faces here in relation to C4. 01:34.140 --> 01:41.880 So in this position, for example, Bishop age six and black is threatening, Bishop takes D2 and then 01:41.880 --> 01:43.410 Knight takes C4. 01:43.740 --> 01:46.710 One of the better moves seems to be from an engine perspective. 01:47.040 --> 01:50.070 CP one Just strengthening the position here. 01:50.070 --> 01:58.500 Ready to recapture if F4 for example E5 and this position Black seems to have good, active aggressive 01:58.500 --> 02:05.580 pieces, it should be about even, especially with an exchange sacrifice to get a bishop of our counterpart. 02:05.820 --> 02:09.960 This position is very interesting to consider engines consider this equal. 02:09.960 --> 02:15.330 So this is a way of getting counterplay with the traditional methods of Rook B eight It's interesting 02:15.330 --> 02:16.230 to consider. 02:17.010 --> 02:26.310 So just to recap, so ninth CB one and here for example, E4 and White can slowly make progress. 02:26.430 --> 02:33.140 Black can get aggressive knights, white can safeguard C4 enough so B1 pertaining to D two. 02:33.180 --> 02:39.360 But you can see, you know G5 this should be an interesting position for white bishop takes E5 is a 02:39.360 --> 02:46.140 forceful option not necessarily needed noise H Knight's a three and white can start to make progress 02:46.140 --> 02:48.900 now with moves like Knight F3 again. 02:48.900 --> 02:55.080 Strengthening, strengthening, strengthening, strengthening and that's indirectly protected by the 02:55.080 --> 02:55.800 Queen. 02:55.800 --> 03:01.770 So this position, for example, should lead to a nice advantage for white. 03:01.800 --> 03:03.570 We're very careful play. 03:04.170 --> 03:06.170 So yeah, there are dangers to retaliate. 03:06.180 --> 03:10.800 This is a standard kind of counterplay system within the King's Indian defense, which is interesting 03:10.800 --> 03:11.550 to consider. 03:11.550 --> 03:21.720 But in the game we have E5 and Spassky plays a very committal direct attack style Knight G4 here. 03:23.230 --> 03:26.820 If this this five hair can be played. 03:26.830 --> 03:34.900 And sure, you know we can still play this to reinforce see for indirectly so g for we have E for. 03:37.920 --> 03:40.980 And at five, now it takes five. 03:41.010 --> 03:44.970 You might think this is a bit strange giving back, you know, a G file, but what is the use of the 03:44.970 --> 03:46.920 G file against the fen cats out here? 03:46.950 --> 03:53.150 It's not that easy to crack open the white king if Bishop takes her five as every Russian schoolboy 03:53.150 --> 03:57.120 he knows a knight on E4 against King's Indian fans is often quite good. 03:57.300 --> 04:03.750 So this position, it's kind of strategically favorable for whites that he foursquare control because 04:03.750 --> 04:05.130 it locks in the G7. 04:05.130 --> 04:08.580 Bishop So this situation, for example, is good. 04:08.580 --> 04:12.360 We're hitting a five and we're going to get a pleasant advantage here. 04:12.480 --> 04:19.230 So anyway, G takes F five keeping control of for 91 B5 and F three. 04:19.230 --> 04:23.790 So that night D one stopping 93, that was preparation there to keep that nice. 04:23.790 --> 04:28.020 But now E4 hitting the rook, the knights not going back just yet. 04:28.020 --> 04:31.470 Bishop b2 e takes her free, Bishop takes her free. 04:31.470 --> 04:37.680 And now you can see that after Bishop takes B2, Queen size B2, it's a bit of a loss for Black's King 04:37.680 --> 04:38.100 safety. 04:38.100 --> 04:41.490 Black is opening themselves up for a potential counterattack. 04:41.490 --> 04:48.600 Here we see 95 Bishop E to keeping flexible rather than the G2 position keeps C4 reinforced. 04:49.080 --> 04:54.030 So C4 is a spot to safeguard generally here. 04:55.830 --> 05:06.900 So if Bishop had gone back here, perhaps Bishop D7 is actually a key idea and then B4 actually because 05:06.900 --> 05:15.810 if we get into the details here, if B takes there is actually 90 fray and actually this position. 05:17.690 --> 05:18.290 Is. 05:18.530 --> 05:21.110 It's kind of interesting why gets. 05:22.530 --> 05:23.370 Maybe. 05:25.210 --> 05:26.160 A small edge. 05:26.170 --> 05:28.270 Yeah, there's interesting dynamics. 05:28.570 --> 05:30.910 But anyway, Bishop E is played. 05:30.910 --> 05:34.150 It seems just logical and sensible to sport C4 like this. 05:34.630 --> 05:35.980 We have four. 05:35.980 --> 05:37.810 But what about this attack? 05:37.810 --> 05:39.580 And it's like hasn't. 05:40.150 --> 05:41.830 Although I say it's logical and sensible. 05:41.830 --> 05:42.880 Isn't the bishop on G2? 05:42.880 --> 05:43.660 Khoza. 05:43.750 --> 05:50.020 It looks as though black's bringing cold winds to the king, as David Bronstein might say, bringing 05:50.020 --> 05:58.990 these cold winds if Queen E7 won't could play C takes B5 with that bishop on E to now being able to 05:58.990 --> 06:05.530 take on B5 this position, one should be able to stabilize the target targets. 06:05.530 --> 06:12.250 So this position for example, with King H1 and preparing to hijack this file if needed. 06:12.400 --> 06:15.310 So this position should be very pleasant for whites. 06:16.300 --> 06:23.950 Okay so F4 and we have G takes F4, which technically is an inaccuracy. 06:23.950 --> 06:32.890 Rook takes F4 is interesting because here Knight E4 like takes a full knight D f2. 06:32.980 --> 06:39.550 This is quite stable for whites with that nice central knight on E4 and these darts quants to try and 06:39.550 --> 06:44.110 tap into these dark square weaknesses that hits a five as example. 06:44.110 --> 06:47.650 This position is better for whites. 06:47.680 --> 06:50.950 Knight takes C5 as a tactic hitting the Queen. 06:50.950 --> 06:59.950 This is better for white so okay here G thanks for was played and we have Bishop H friend and it looks 06:59.950 --> 07:05.320 very dangerous but now an amazing move in circumstance. 07:05.350 --> 07:05.830 Guess what? 07:05.830 --> 07:12.010 Petrosian plays and he does grab an attacking ingredients which we've spoken in this course. 07:12.070 --> 07:12.940 There's a section. 07:13.690 --> 07:13.850 Yeah. 07:14.020 --> 07:14.800 I'll give you a clue. 07:14.830 --> 07:17.050 How does he grab Bishop without a counterpart? 07:18.130 --> 07:20.350 Both sides have got line square bishops. 07:20.350 --> 07:22.720 Black has these weaknesses around the king. 07:22.720 --> 07:24.460 This kind of vacuum Weaknesses? 07:24.880 --> 07:25.330 Yeah. 07:25.330 --> 07:28.510 He gets the ingredients, the attacking ingredients. 07:28.540 --> 07:31.690 93 bishop without counterpart offering exchange. 07:32.590 --> 07:40.240 If F takes E5 Queen G five Jack and it's going to get mated if rookie one queen inch four is too powerful. 07:41.410 --> 07:45.220 So for example taking a queen takes E one and it's going to get mated. 07:45.550 --> 07:48.820 Or if the F two then rook takes F4 is too powerful. 07:48.850 --> 07:54.070 This is just a very strong attack that's going to crash through with this strong attack. 07:54.220 --> 07:55.090 So that's first thing. 07:55.090 --> 07:57.040 Rook takes age to checkmate. 07:57.040 --> 08:00.130 And this is just sort of win material with queen sites and free check. 08:00.430 --> 08:05.920 So this is the exchange up for black so it's quite vicious situation. 08:05.920 --> 08:13.300 So 93 in the circumstances is brilliant and it's kind of trying to hijack these diagonals, which Black 08:13.300 --> 08:16.300 used to control and now dozens and white hands. 08:16.300 --> 08:20.350 This bishop is essentially being amplified because it hasn't got a counterpart. 08:20.350 --> 08:25.990 So it's an extreme imbalance, an extremely favorable advantage to have this bishop counterpart in this 08:25.990 --> 08:29.500 situation, especially with the lines where it's quite raw. 08:29.530 --> 08:37.600 We have Knight G6 and now Bishop G4 going into the E6 six Square is a lovely aspect, but Black has 08:37.600 --> 08:39.160 stopped Bishop E6. 08:39.160 --> 08:41.190 Guess what Tigran Petrosian plays here. 08:41.830 --> 08:47.590 Actually, before we even get into that, if Rook takes F4, if it wasn't stopped then this position 08:47.590 --> 08:53.530 is exceptionally dangerous for black of the Queen H eight check and knight F five is checkmate if Queen 08:53.530 --> 08:58.390 H for again the Bishop e6 then horrible things happen after 94. 08:58.390 --> 09:05.500 Bishop takes after seven Check King takes king H one Black is in a world of pain here in this position. 09:05.950 --> 09:11.290 So that's a nasty check and a knight 68 as example. 09:11.290 --> 09:16.960 So Spassky tries to stop the use of E6 with knight takes F4. 09:16.960 --> 09:17.770 So guess what? 09:17.950 --> 09:26.950 When Petrosian plays here, which further amplifies the light square Bishop, it gives up well, 400 09:26.950 --> 09:27.190 points. 09:27.190 --> 09:32.920 He gives up another exchange and the Knights are ready to jump into various amazing squares here. 09:32.920 --> 09:38.140 Now, these knights go from a defensive role to a vicious attacking role. 09:38.140 --> 09:44.950 So night E4, plenty of interesting threats and opportunities are building up. 09:44.950 --> 09:53.770 Now we have Queen H h4 if B takes C4 knight at five as example where threatening Queen G seven champ 09:53.770 --> 09:56.470 mate, the power of the pin piece or pawn is illusionary. 09:56.470 --> 10:03.910 So she takes Queen G seven is mate and also if queen AFAIK Queen F six is actually a force mate in five. 10:04.150 --> 10:06.610 So much being two exchanges down. 10:06.610 --> 10:12.490 This is too much pressure to bear after Knight G five for example, Knight takes F seven, Bishop takes 10:12.490 --> 10:13.360 f seven check. 10:13.360 --> 10:15.490 It's all crashing through on have seven. 10:15.970 --> 10:22.130 So we have Queen H four and here knight takes these six, Queen G five. 10:22.130 --> 10:24.160 Check King H one. 10:24.530 --> 10:32.750 And we have rook a seven if queen size e free bishop takes F seven is kind of vicious with Queen H eight 10:32.750 --> 10:35.120 check and a five check. 10:35.240 --> 10:39.530 And yeah, if King takes we would take their and take the queen. 10:39.830 --> 10:49.010 But in this case we play Bishop E6 check and we do get a check to take the queen anyway so och rook 10:49.010 --> 10:55.820 a seven ignoring e three we have Bishop takes F seven Schenk rook takes F seven and now one of the most 10:55.820 --> 11:01.280 beautiful ten where have chosen iconic moves in my view, one of the most beautiful. 11:01.280 --> 11:05.630 When I think of team chosen, I think of this winning combination in this game. 11:06.080 --> 11:10.040 So what this won't play here, which just basically wins material. 11:10.040 --> 11:12.680 What would you play for 500 points? 11:12.680 --> 11:16.190 There's an amazingly crushing resource here. 11:16.190 --> 11:20.180 Chapel checks even the seemingly totally outrageous checks. 11:20.840 --> 11:22.700 So hopefully you find it. 11:23.210 --> 11:24.440 You might want to pull the video. 11:25.550 --> 11:29.300 So it's Queen H eight check end of game. 11:29.300 --> 11:33.350 So King takes those, Knight takes F seven check, and we're just the piece up. 11:33.350 --> 11:34.340 Thanks very much. 11:34.910 --> 11:39.020 So I find this game a beautiful kind of counterattack game. 11:39.140 --> 11:43.910 So even the defensive world champions can play amazing counterattack chess. 11:43.910 --> 11:47.660 They're picking up rapidly in this example the ingredients. 11:47.660 --> 11:54.170 The bishop about the counterpart, the pin pieces, ingredients, king safety issues, all all the pieces 11:54.170 --> 11:58.100 coming together as a team to exploit the weakened king, in effect. 11:58.100 --> 12:04.400 And it was self weakened for letting the opponent commit themselves with pawns, irreversible pawn moves. 12:04.700 --> 12:11.500 So sometimes counterattacks are so powerful, especially if you factor in pawns are the only piece or 12:11.780 --> 12:13.370 they're irreversible. 12:13.370 --> 12:15.350 So it's like irreversible damage being done. 12:15.350 --> 12:20.360 So the power of the counterattack instead of a direct attack is very lucrative. 12:20.360 --> 12:23.960 Sometimes you get the opponents to weaken themselves. 12:24.290 --> 12:27.380 That's a bit like strengthening your position, but in reverse. 12:27.410 --> 12:31.610 Getting your opponent to weaken their position is two sides in a way of the same coin. 12:31.610 --> 12:37.610 Either you're strengthening your position like nimzowitsch prophylaxis over protection, restraint, 12:37.610 --> 12:41.630 blockade, you're restraining your possession, or kind of the opponent's weakening theirs. 12:41.750 --> 12:47.630 And you get this amazing attack potential if the opponent's really committed all these weaknesses just 12:47.630 --> 12:53.990 waiting to be exploited, then you like pick up on the counter, attack the essential attacking ingredients. 12:53.990 --> 13:02.060 So attack is the best form of defense and this is a fantastic counter-attacking game example in my view. 13:02.060 --> 13:04.520 I hope you enjoyed this game as much as me. 13:05.240 --> 13:05.840 So much.
