WEBVTT 00:01.080 --> 00:01.820 Hi there. 00:01.830 --> 00:06.450 In this lecture, we see a theme boggle tangible against Aron Nimzowitsch. 00:06.450 --> 00:11.460 So Bogoljubov was later to have a world championship match with Alexander Alekhine. 00:11.730 --> 00:17.250 But in the Carlsbad tournament of 1929, this was nimzowitsch his finest hour. 00:17.250 --> 00:23.340 It's interesting to see games from installments and especially against Bogoljubov So D4 from Bogdan 00:23.640 --> 00:29.940 Nimzowitsch plays nine of six C for E six is brainchild opening the Nims are engine to is aiming to 00:29.940 --> 00:33.540 double the pawns and he does so immediately. 00:33.540 --> 00:34.800 Bishop take C free. 00:34.830 --> 00:38.280 We have B tanks b6g free. 00:38.280 --> 00:39.360 Bishop B seven. 00:39.480 --> 00:43.050 Bishop G two both sides Castle and now Rookie eight. 00:43.050 --> 00:46.470 This is a very interesting kind of waiting move. 00:47.610 --> 00:55.440 It's sometimes designed to play E5 in certain variations, but if we look concretely, if H six was 00:55.440 --> 00:57.630 played D five, we can just play D six here. 00:57.630 --> 00:59.070 It's not such a big deal 01:02.290 --> 01:06.300 as as long as in this position E takes D five. 01:06.300 --> 01:14.910 That would be a mistake of note h four And here this situation is a is to White's advantage. 01:15.900 --> 01:21.480 So there is there are some points the rookie eight early, sometimes 94 can be a useful resource in 01:21.480 --> 01:22.650 some of the variations. 01:23.930 --> 01:26.690 So rookie ain't we have rookie one. 01:26.690 --> 01:36.530 So for example here, if D five, E takes 94, there is actually 94 well supported by the rook and pawn 01:36.530 --> 01:38.480 and black has the advantage there. 01:38.660 --> 01:42.980 Or if we look at 94 then we can use 94 here as well. 01:43.520 --> 01:47.570 See text and play nine, take four and all of a sudden E two is under fire. 01:47.570 --> 01:55.310 So yes, rookie A is a little bit mysterious, but it has some elements of prevention. 01:55.910 --> 02:02.570 We have Rook E one, DD six, Quincy two and now Bishop E four. 02:02.570 --> 02:08.540 So this keeps a lock and key over white playing E four If I wanted to play E four with Quincy to an 02:08.540 --> 02:10.430 E4, and that's not there at the moment. 02:10.430 --> 02:15.950 So Queen bee free we have 96 and Bishop have one. 02:15.950 --> 02:16.850 So it moved 12. 02:16.850 --> 02:22.250 It looks as though White's really quite passive, but can Nimzowitsch actually make something out of 02:22.250 --> 02:24.050 this particular pawn structure? 02:24.920 --> 02:29.480 And there is an option option or an option to take on F3 as well, but that's going to give White a 02:29.480 --> 02:30.860 lot of pressure potentially. 02:31.100 --> 02:40.520 We see E five So this is interesting also Knight A four like a five rather is interesting for C five. 02:40.520 --> 02:47.900 This would be constituting, for example a very interesting position for blank where. 02:48.840 --> 02:50.970 There's great control over the light squares. 02:50.970 --> 02:57.660 And for example, here we could play E five and then take on G two and then Quincy eight. 02:57.660 --> 03:02.990 And this resembles another Nimzowitsch game where the Queen replaced the bishop on the diagonal. 03:03.000 --> 03:07.230 So this variation is just actually already just better for black. 03:07.260 --> 03:09.510 If you look at white structure, it's pretty miserable. 03:10.980 --> 03:14.670 So we see E5 though that's a great move as well. 03:14.670 --> 03:16.140 D takes E5. 03:17.400 --> 03:25.950 If Bishop E free, we can play 95 and try and try and tap into the weakness of C4 somehow. 03:26.190 --> 03:33.120 E4 could be useful here and actually we could play the transformative D5 in this situation to take C4. 03:33.150 --> 03:39.780 The result here, if we have this nice g for Bishop C one queen of six, we're really doing quite comfortably 03:39.780 --> 03:41.460 here and we're looking at F two. 03:41.820 --> 03:49.110 If every E takes nine, takes 90 C four, as example on Knight, it's a really quite aggressive here 03:49.440 --> 03:53.670 and we're doing really well off the Queen E, six, H and G. 03:53.880 --> 04:03.750 Both knights can conspire on the E three square sometimes if Bishop G to the 95 Queen D one we can consider 04:03.750 --> 04:09.240 H six just a simple h six just waiting for white to do something. 04:09.630 --> 04:14.550 And once you really just tie it down here, we don't have to be in a rush to take any pawns or anything. 04:14.550 --> 04:17.910 We can have just the massive binding on the position like this. 04:18.360 --> 04:23.220 So D takes though, it kind of isolates these double pawns. 04:23.220 --> 04:25.200 So there is a bit of a transformation here. 04:25.290 --> 04:32.820 Nine six If Bishop G to this just will lose material because the back row is not connected up yet. 04:34.560 --> 04:37.320 If we look at that rocket's potentially unprotected, we can just play. 04:37.320 --> 04:42.300 Bishop takes our free E text and now Knight takes our free check to win E one. 04:42.600 --> 04:46.590 So a knight takes E five was played, Rook takes E five. 04:46.590 --> 04:53.820 So this is a great move keeping black structure intact, keeping a grip on the E file. 04:53.970 --> 04:57.930 We have bishop and former rookie eight and Free Bishop B seven. 04:58.020 --> 05:04.410 Perhaps better in terms of prevention would be Bishop C six just in case there's any C five. 05:04.710 --> 05:05.580 So this is interesting. 05:05.580 --> 05:11.640 The modern positional players seem much more emphatic sometimes about prevention like Karpov and Adams. 05:11.640 --> 05:15.810 But with Bishop B seven, this is actually kind of encouraging. 05:15.840 --> 05:21.060 C five under the right circumstances because of the unprotected piece on B seven. 05:21.930 --> 05:26.700 So if Bishop C six, as example, the knight could come to D seven, Queen come to F six. 05:26.700 --> 05:28.260 It's a really comfortable position. 05:28.740 --> 05:37.200 So Bishop B some we have Rook 8190 7e4, Queen F six, Bishop G two and now 95. 05:37.200 --> 05:46.830 This is actually a little bit of an inaccuracy if A five queen B 595 Black's doing so well here, but 05:46.830 --> 05:47.670 95 was played. 05:47.670 --> 05:53.190 We have rook D two This was once moments to try something like C five. 05:54.660 --> 05:57.510 Yeah, if g five then sure. 05:57.510 --> 06:00.810 Bishop takes E five, D takes D seven. 06:00.810 --> 06:04.650 You can see that White's been given a tiny bit of play. 06:05.420 --> 06:06.320 Bounce. 06:08.040 --> 06:09.930 What's the alternative if DD takes? 06:09.930 --> 06:11.520 The thing is Bishop takes hare. 06:12.780 --> 06:18.540 And if Queenside Rook rd seven looking at F seven and you can see that there's a bit of play here. 06:18.720 --> 06:20.490 The four, it's even. 06:20.970 --> 06:26.850 So this is one of the reasons why, as well as prevention, we shouldn't be asking for certain possibilities 06:26.850 --> 06:29.820 by having unprotected pieces or downsides. 06:29.820 --> 06:34.170 That's going to encourage exploitation of unprotected pieces. 06:34.170 --> 06:45.120 So anyway, Nimzowitsch was let off a bit with Rocket D two rookies, seven Rook D one again C five 06:45.120 --> 06:47.850 Here is actually a good shot. 06:47.850 --> 06:54.030 So D takes Bishop takes E five, and if Queen takes, then there's a four. 06:55.370 --> 07:01.250 And if Queen H five, Queen RD one, this is going to be actually a position where. 07:03.160 --> 07:06.970 Blacks only going to get a small edge in this rook and pawn ending. 07:07.720 --> 07:12.790 And if we look at this again with Rook takes five, that actually runs into a four and black would actually 07:12.790 --> 07:15.150 be losing after E five looking at B seven. 07:15.160 --> 07:21.640 So this issue, it's it's in terms of prevention, it's good if we don't have tactical downsides. 07:21.760 --> 07:23.590 Yeah we're just asking for trouble really. 07:23.590 --> 07:29.890 Sometimes prevention or not, we shouldn't be having downsides that undetected pieces they can crop 07:29.890 --> 07:32.650 up as liabilities in the variations. 07:32.650 --> 07:40.480 But I played the Passive Rook 81 and we have Bishop C six finally dissuading C five now that there's 07:40.480 --> 07:42.970 a safe B takes so rook have. 07:43.120 --> 07:44.470 So that's a great preventative move. 07:44.470 --> 07:51.280 Now finally, so preventive preventative by not having an unprotected piece, we have rook eight Bishop 07:51.280 --> 07:54.330 f186 should be two. 07:54.340 --> 07:56.710 So how to transform this structure? 07:56.800 --> 08:03.970 We have King H So improving the king a little bit or trying to queen a free queen e sex this pawn cannot 08:03.970 --> 08:04.720 be taken. 08:04.720 --> 08:08.950 We see Quincy one If queen takes a seven, we simply play rook eight. 08:08.950 --> 08:09.940 Thanks very much. 08:10.420 --> 08:11.740 Just trapping the queen. 08:12.580 --> 08:15.130 So Queen C one But now. 08:15.130 --> 08:15.580 Yes. 08:15.580 --> 08:17.230 What would you play with Black for? 08:17.230 --> 08:18.100 Ten points. 08:20.370 --> 08:20.750 Yep. 08:20.840 --> 08:22.860 F while trying to undermine the structure. 08:24.570 --> 08:28.740 If you take C for this will be missing a tactical shot. 08:29.010 --> 08:31.020 Can you see what White would play here? 08:33.410 --> 08:34.700 In this moment. 08:34.730 --> 08:40.220 This bishop takes H six again, kind of under protected pieces and points here. 08:40.220 --> 08:46.970 Bishop, S.C. four And one could win basically a perpetual check draw out of this situation, totally 08:46.970 --> 08:48.230 salvaging situation. 08:48.230 --> 08:50.750 So this creates some liability that's avoided. 08:50.750 --> 08:56.240 So that's great to avoid that Nimzowitsch played F5 just to undermine the structure. 08:56.570 --> 08:57.350 E Thanks. 08:57.350 --> 08:58.340 Queen takes her five. 08:58.340 --> 09:03.470 Queen RD two If Bishop takes E five here, Rook takes E five. 09:03.470 --> 09:09.950 This situation with Queen H five and say this G for Queen H Well, this is just better for Black Black's 09:09.950 --> 09:11.330 dominating that file. 09:12.740 --> 09:14.900 So Queen D two we have Queen F seven. 09:16.820 --> 09:19.610 This is looking at C four again sometimes. 09:19.610 --> 09:23.210 So we have Queen D for protecting C four among other things. 09:23.450 --> 09:25.820 If Bishop takes E five, Rook takes E5. 09:25.820 --> 09:36.410 This situation we can play here in this situation, it's just better for black here. 09:36.440 --> 09:39.500 Overall, after King Black's fine. 09:39.500 --> 09:43.930 For example, if Bishop f one we can play nine six our free check. 09:44.060 --> 09:45.710 It has to be careful about free. 09:46.340 --> 09:52.010 If rook df1 96 this situation we can double the pawns over here. 09:52.130 --> 09:53.540 And this is similar. 09:53.870 --> 09:55.640 Well, this is a bit of a nightmare we can play. 09:55.640 --> 09:56.720 Bishop takes our free. 09:56.750 --> 10:01.160 This is great great for playing so queenly for tried 96. 10:01.160 --> 10:07.430 This unveils an attack simultaneously against E2 and F4 to do even more structural damage. 10:07.430 --> 10:10.400 Bishop dd free is played if Bishop C one. 10:10.400 --> 10:12.320 Yes, we're just going to take on E two. 10:12.320 --> 10:13.430 No backfire. 10:13.520 --> 10:19.940 So Bishop de Fray Knight takes F4, Queen takes F4, Queen takes F4 and look at white structure. 10:20.300 --> 10:21.920 They're like grandma's teeth, hair. 10:21.920 --> 10:25.880 I joked in a YouTube video many years ago, but it is look at the structure. 10:25.880 --> 10:29.840 This is such a success in terms of destroying the opponent's structure. 10:29.960 --> 10:34.850 And there is really an exploitable weakness now this F4 so that's targeted. 10:35.660 --> 10:38.270 So F five we have Bishop D seven. 10:38.270 --> 10:39.890 This pawn is being picked off. 10:40.370 --> 10:42.110 And is it enough to win? 10:42.290 --> 10:44.540 Well, the rest of the structure is also pretty weak. 10:44.540 --> 10:50.450 So Rook f2 we have rook takes e to Bishop takes Ede. 10:50.450 --> 10:52.250 So that's the only way. 10:52.370 --> 10:55.070 Because if rook takes it, it would take on D three. 10:55.100 --> 10:57.680 So Rook So Bishop takes E two. 10:57.710 --> 11:04.790 We have rookie eight king f2 rookie five rook five Nimzowitsch doesn't mind simplification here. 11:04.790 --> 11:09.380 He's confident after G five fixing the f pawn. 11:09.490 --> 11:12.320 This is a winning ending so rook times details. 11:13.670 --> 11:19.640 This does give a natural path for the king to use to come to see five later. 11:19.640 --> 11:22.610 And you can imagine when bishop he thinks how the stronger this will be. 11:23.660 --> 11:27.290 So c five was played now little too late. 11:27.320 --> 11:30.830 B takes bishop a six, E four. 11:31.460 --> 11:39.020 So this is creating potentially a 2 to 1 pawn majority A for King g7a5e takes our free so a 2 to 1 pawn 11:39.020 --> 11:49.820 majority King takes a free king F six king every king E five Bishop C for Bishop G for 6h5. 11:49.820 --> 11:50.840 The pawns are pushed. 11:50.840 --> 11:52.730 This poor majority is to be exploited. 11:53.090 --> 12:01.790 So Bishop D one should be now g four end of game about resigned here if Bishop eight six as example 12:01.790 --> 12:04.130 g3h takes h next. 12:04.130 --> 12:14.570 What we can do is just transition into a winning king and sometimes so g two can have to well, we can 12:14.570 --> 12:15.770 get our king to be aggressive. 12:15.770 --> 12:22.520 This ending scenario is going to be absolutely winning just with the king coming to scoop up the dart 12:22.530 --> 12:25.310 square pawn on C free and that's a big pass pawn. 12:25.520 --> 12:27.860 So here this is getting bad. 12:28.310 --> 12:30.880 So yes, the final position G four. 12:30.890 --> 12:37.160 So it's interesting how you know a player relatively strong in the world at the time and to be playing 12:37.160 --> 12:47.360 Alexander Alekhine is just positionally kind of crushed but it seems as though Nimzowitsch perhaps shouldn't 12:47.360 --> 12:53.660 have advertised how strong he is with the tournament book it seems, you know, maybe there was a greater 12:53.660 --> 12:57.020 possibility of being chosen as a world championship challenger. 12:57.020 --> 13:02.150 Challenger if sometimes had been a little bit more modest in his writings. 13:02.150 --> 13:07.880 He seems to be advertising his system as well as detailing the annotations of the tournament. 13:07.880 --> 13:11.030 So it's interesting that it's annotated, the whole tournament. 13:11.030 --> 13:17.450 But yeah, it does seem to be pretty systematic this game in terms of doubling the structure on both 13:17.450 --> 13:23.600 sides of the board, quite vivid example of pawn structure damage and transitioning the pawn structure, 13:25.040 --> 13:28.190 modern accuracies, improving with modern super grandmasters. 13:28.190 --> 13:32.150 So as part of prevention, not to have liabilities is something to be. 13:32.270 --> 13:32.900 Borne in mind. 13:33.200 --> 13:35.950 Bishop seven is a potential liability to see five sometimes. 13:35.960 --> 13:37.940 Why take that theoretical risk? 13:37.940 --> 13:43.820 It's good to shut down as much as possible, take absolute to the absolute maximum and the idea of prevention. 13:44.060 --> 13:46.220 So not just active surveillance. 13:46.490 --> 13:51.050 If we take NIMS, which is idea that for example, passports, we need them under lock and key, we 13:51.050 --> 13:57.590 need things under lock and key or maximum surveillance or maximum dissuasion of tactical possibilities. 13:57.590 --> 14:03.620 But it was relatively under control and why it didn't really get any counts by the way he played it. 14:03.620 --> 14:06.350 So yeah, a real, you know, one way game here. 14:06.350 --> 14:07.460 I hope you enjoyed this. 14:08.040 --> 14:08.930 Thanks very much.
