WEBVTT 00:01.180 --> 00:02.090 Hi there. 00:02.110 --> 00:05.200 In this lecture, we see Aaron Nimzowitsch against a very talented player. 00:05.410 --> 00:06.870 I'll check out two articles. 00:06.880 --> 00:08.080 Witty quotations. 00:08.080 --> 00:10.870 He is absolutely brilliant on the quotations front. 00:11.320 --> 00:21.640 So this is a 1929 Carlsberg tournament, round 21 DD four, from which we see Kerr playing 9f6c4g6f3. 00:21.640 --> 00:25.540 We go into a similar variation of the King's Indian defense. 00:26.110 --> 00:34.960 So we see black casting Bishop Efrain like BD seven and this move actually allows quite a positional 00:34.960 --> 00:36.040 move already from White. 00:36.040 --> 00:37.120 Can you see what that is for? 00:37.120 --> 00:37.690 Ten points? 00:37.690 --> 00:38.770 What would you play here? 00:38.770 --> 00:40.660 There is a kind of weakness for the last move. 00:40.660 --> 00:42.610 It's not looking at H three. 00:43.300 --> 00:48.070 Yeah, we can sneak in nine H free the Knights quite good on F two actually. 00:48.070 --> 00:50.470 It supports center more. 00:50.710 --> 00:52.540 It's got some options. 00:52.810 --> 00:53.920 So that's a nice move. 00:53.920 --> 00:58.960 Nice H three we have E five and now D five. 00:59.650 --> 01:01.690 A five might have two and now B six. 01:01.690 --> 01:05.620 This is a very passive treatment of the king's engine defense. 01:06.160 --> 01:09.100 Usually Black tries to create some dynamic play. 01:09.100 --> 01:16.540 So for example, night h5g4 to play 94 to try and open up the dance grab bishop and if queenly to just 01:16.540 --> 01:20.910 use a pawn sac if needed to try and get some peace activity. 01:20.920 --> 01:26.290 So this situation, even though technically it's going to be better for white, is often the way for 01:26.290 --> 01:31.930 black to play it to try and generate counterplay before it's too late, before there's an almighty grip 01:31.930 --> 01:32.800 on the possession. 01:32.800 --> 01:34.870 But B six really doesn't help. 01:35.920 --> 01:40.030 We see Queen D two so already with authority now on this diagonal. 01:40.660 --> 01:45.490 So No H six which could have been used for four King seven or 19 H five. 01:45.490 --> 01:53.680 There's no H six, we see 95 and now Bishop G five also good here already once possession is great off 01:53.680 --> 02:01.330 the G for this position is a great grip on the possession and here we could play like this with advantage 02:02.260 --> 02:06.700 and we can castle queenside So Bishop G five though is interesting. 02:06.850 --> 02:12.400 Bishop d7g for Queen and H for King H eight. 02:12.850 --> 02:16.660 So this doesn't look good with the rook on the H file. 02:16.690 --> 02:17.890 It doesn't look particularly good. 02:17.890 --> 02:23.830 H five might be an interesting try and these trying to tempt a mistake from white. 02:23.830 --> 02:33.310 But Bishop e2 h takes here there's bishop takes f6 Bishop takes up six, F takes g four and it's worth 02:33.640 --> 02:37.300 giving up the darts Chi bishop in this example. 02:37.300 --> 02:39.400 But there is another example. 02:41.150 --> 02:47.150 If it doesn't play Bishop e2 and goes for Bishop saying same sex black can employ a positional pawn 02:47.150 --> 02:56.240 sacrifice here with King G seven, which increases dramatically King safety and H six King is only a 02:56.240 --> 02:58.910 small edge for white, and he is even worse. 02:58.910 --> 03:02.450 That's just equal for black with the bishop power and a target on H four. 03:02.450 --> 03:05.420 And that's the king's going to be quite safe there. 03:05.780 --> 03:12.860 So H five was an interesting try to try and mix things up, but King H eight is a bit passive again 03:12.950 --> 03:20.090 and H five So actually there's a threat immediately of H six winning the Bishop. 03:20.090 --> 03:23.780 So we have G takes and now Nimzowitsch gives up the dark square. 03:23.780 --> 03:31.790 Bishop Bishop takes them six, Bishop takes up six, rook takes H five, Bishop G seven and there's 03:31.790 --> 03:34.880 a nice positional move improving one of the pieces. 03:34.880 --> 03:36.080 Can you see what it is. 03:36.710 --> 03:38.840 So there's a net gain effect. 03:38.840 --> 03:40.760 Sometimes we have to go backwards to go forward. 03:40.760 --> 03:42.830 So what do you think this positional move is? 03:42.830 --> 03:46.460 Which engines also like on this occasion? 03:48.520 --> 03:49.210 Okay. 03:50.650 --> 03:52.600 For 100 points, what would you play here? 03:53.260 --> 03:55.660 It's really a position devoid of counterplay. 03:56.830 --> 04:00.460 This is a very sad version of the kings of Defense without any F5. 04:00.460 --> 04:07.390 So no one reinforces the depressing nature of affairs here for the knight to occupy F5. 04:07.780 --> 04:13.390 So f six, Knight and Queen H two first H 6.9 G free. 04:14.380 --> 04:21.790 So both F6 and H six are coming under blockade heavy restraints, which gives black basically a dead 04:21.790 --> 04:22.520 position here. 04:22.540 --> 04:27.860 Bishop e2 rookie a King F2 and one can just build up here without too much worry. 04:27.880 --> 04:31.990 We have royal cage for Queen E eight. 04:32.860 --> 04:35.530 So rook h will vacated h five. 04:35.980 --> 04:38.890 We have Rook hg1. 04:39.040 --> 04:40.150 Bishop F eight. 04:40.660 --> 04:41.490 King G two. 04:41.500 --> 04:43.800 The king improves itself a little bit. 04:43.810 --> 04:50.410 So noice H five the first night blockade and looking at F six the Queen protects F six now F four. 04:50.740 --> 04:54.250 This is looking really dangerous for black. 04:54.250 --> 04:55.500 We have 90 eights. 04:55.510 --> 05:02.990 If E takes f four, this will open up essentially the possibility of this diagonal if E takes F4. 05:03.010 --> 05:09.970 So e five here opening up the bishop soon to use D three is going to be really dangerous for black. 05:09.970 --> 05:17.020 This scenario where Bishop DD free comes along is just super dangerous for black, and if white can 05:17.020 --> 05:19.900 get this dominating position, it's on the way to winning. 05:20.230 --> 05:30.100 So 98 is tried Bishop f37 and now another positional maneuver. 05:30.100 --> 05:30.880 So guess what? 05:30.880 --> 05:32.710 Nimzowitsch plays here for another blockade. 05:32.710 --> 05:34.180 In fact, destination. 05:34.630 --> 05:37.960 So blockade is the ultimate form of pawn restraints. 05:37.960 --> 05:39.430 We've restrained H six. 05:39.430 --> 05:41.830 Can we restrain f6? 05:41.830 --> 05:42.730 That's the challenge. 05:42.730 --> 05:43.990 So what would you play here? 05:47.240 --> 05:48.010 92. 05:48.010 --> 05:52.450 We want to reroute the night, improve the night blockade on F5. 05:52.480 --> 05:54.130 Bishop E seven, King H one. 05:54.130 --> 05:56.440 The King improves itself slightly. 05:56.530 --> 05:58.540 Slight improvements to the position. 05:58.540 --> 06:03.640 So this is a great positional plane e.g. free king of 895. 06:03.640 --> 06:05.860 So it's a beautiful blockading scenario. 06:05.980 --> 06:07.780 Blacks The void of counterplay. 06:07.810 --> 06:08.720 Rook g eight. 06:08.760 --> 06:10.060 We have queenly to. 06:11.580 --> 06:11.880 Rook. 06:12.000 --> 06:12.960 See eight rook. 06:12.960 --> 06:13.800 H two 06:16.500 --> 06:17.630 The king flees. 06:17.640 --> 06:18.360 Be free. 06:18.360 --> 06:19.980 So this is an interesting move. 06:20.010 --> 06:21.930 It could be as a preparation. 06:21.930 --> 06:24.420 Quite often if we want to play a free there's a four. 06:24.420 --> 06:33.360 So this be free move is often in a preparation for a free and and B for we have king a free player tries 06:33.360 --> 06:40.860 to dissuade b4 with rook eight now before it is a good move, but we can also just keep our options 06:40.860 --> 06:41.280 open. 06:41.280 --> 06:46.740 Queen C one and didn't have to wait too long here for a terrible mistake. 06:46.740 --> 06:50.160 Bishop F eight This is a weakness of the last move. 06:50.160 --> 06:51.150 It's weakened. 06:51.150 --> 06:54.030 F six and what would you play here? 06:54.030 --> 06:58.380 Which is just basically a winning game after this next move. 06:58.770 --> 07:01.260 So the clue is there's a weakness of the last move. 07:02.790 --> 07:05.910 Okay, The knights are not just pressing and blockading. 07:05.910 --> 07:09.600 They can actually be functional and react to weaknesses of the last move. 07:09.600 --> 07:15.600 So Knights H for hitting the Queen, driving the Queen away from F6 and Black's game now crumbles. 07:15.600 --> 07:18.240 So losing a pawn followed by the exchange. 07:18.240 --> 07:21.060 This isn't the best of news for black queen. 07:21.060 --> 07:24.660 Thanks g5e takes her four. 07:24.690 --> 07:27.990 If H takes g five, F takes g five. 07:27.990 --> 07:31.410 This situation is just driving the advantage forward. 07:31.770 --> 07:34.530 So E takes her four, G takes H six. 07:35.100 --> 07:36.180 Queen 87. 07:36.360 --> 07:37.890 The Queen was attacked with the rook. 07:37.890 --> 07:45.930 So here Queen takes her for bishop, takes h six Queen f6 check Kinsey eight and they'll knight F five. 07:46.260 --> 07:53.820 This is reinforcing the advantages Bishop takes her five, E takes King B seven and not Minding Queen's 07:53.820 --> 07:54.630 coming off. 07:54.810 --> 07:55.680 We have a location. 07:56.160 --> 08:04.500 Queen's come off leaving black in an almighty pin rook g sex king and now f6. 08:04.500 --> 08:11.070 So the bishop is offered a great diagonal to reroute and to make the position really crumble for black 08:11.070 --> 08:16.590 Bishop G for Chick King, the Bishop e six, King e eight. 08:16.740 --> 08:24.330 And then Bishop takes F seven changes winning material King takes F seven, rook H takes H six end of 08:24.330 --> 08:24.750 game. 08:24.750 --> 08:31.770 We don't need to explain why does the rook up here on this occasion so quite a controlled positional 08:31.770 --> 08:40.470 masterpiece with blockading on Black's pawns, improving the possession and there's a bit of a wait 08:40.470 --> 08:46.590 for a really destructive weakness of the last move where Black just blundered f6 so a crushing one way 08:46.590 --> 08:48.930 game without much counterplay. 08:50.340 --> 08:57.330 So yes, Nimzowitsch Setting the tone here for future generations of positional players blockading strategy 08:57.330 --> 09:04.770 really emphasized in this game when we have the knights blockading on F five and H five, blockading 09:04.770 --> 09:07.500 F six and H six respectively. 09:07.500 --> 09:14.250 So a very nice blockading example and it was in nimzowitsch his finest hour like this game example because 09:14.250 --> 09:18.000 it's also what's called Nimzowitsch is finest hour to be aware of. 09:18.000 --> 09:22.850 Carlsbad, 1929 Nimzowitsch won this tournament, very prestigious tournament. 09:22.860 --> 09:29.370 It was basically a fantastic achievement for Nimzowitsch, you know, so one of his best ever tournament. 09:29.370 --> 09:32.670 So it's nice to see this beautiful blockading example. 09:33.420 --> 09:35.970 I hope you enjoyed it so much.
