WEBVTT 00:01.320 --> 00:01.980 Hi there. 00:02.010 --> 00:05.880 In this lecture, we see Alexander Alekhine playing against Hugh Alexander. 00:06.330 --> 00:08.520 So he has a very interesting wiki page. 00:08.520 --> 00:10.770 He works at Bletchley Park. 00:11.760 --> 00:15.960 So cryptanalysis, not crypto cryptanalysis. 00:15.960 --> 00:20.460 So yeah, encryption decryption rather. 00:20.460 --> 00:22.500 Mostly decryption, presumably. 00:22.500 --> 00:23.100 So anyway. 00:23.130 --> 00:30.450 1936 Nottingham Thomas round 11 D4 from Alexander Alekhine. 00:30.960 --> 00:38.580 So Knight f6 we have C4 e6 Knight F3 so Queen's Indian territory and actually it's a bow go Indian defense 00:38.580 --> 00:48.060 here now Bishop b4 check we see Knight bd to be 6g3 Bishop B seven Bishop G to both sides. 00:48.060 --> 00:54.660 Castle Bishop takes D2 so giving up the Bishop voluntarily here, not inflicting structural damage. 00:54.660 --> 00:56.490 So how would you take here? 00:58.120 --> 01:00.580 So we have now a bishop of our counterpart. 01:01.900 --> 01:03.970 Ideally, we want either king, right? 01:04.000 --> 01:05.560 That's the dance square around the king. 01:05.560 --> 01:08.080 So how would you take care for ten points? 01:08.470 --> 01:10.390 I believe this is absolutely logical. 01:10.390 --> 01:17.480 Queen 62 So this means that we can play a subtle move and have a bishop looking at the king here. 01:17.500 --> 01:24.700 So we have d6 b free knight Bd7 Bishop b2 so rook b8. 01:24.700 --> 01:29.140 So there's a strategy of amplification when we have such a bishop, especially with our counterpart, 01:29.170 --> 01:33.880 it's already basically naturally amplified that there's no counterpart Don't square. 01:33.910 --> 01:41.770 Bishop We have Rook 81, 94 and now Queen E4, a very nice move, putting pressure on that knight learning 01:41.770 --> 01:43.270 occupied E4. 01:43.780 --> 01:47.920 But here now after F5 a really. 01:48.620 --> 01:53.870 Interesting move indeed to find this bishop rather than it being locked in. 01:53.870 --> 01:54.950 And then he points. 01:54.980 --> 01:55.610 Guess what? 01:55.610 --> 01:56.600 White Plains. 01:59.930 --> 02:00.680 Okay. 02:01.550 --> 02:07.550 D5 Yeah, D5 opens up the bishop and you might think, Well, isn't that a weak pawn on D5? 02:07.580 --> 02:11.360 That's the interesting part here because of this Bishop counterpart. 02:11.390 --> 02:17.960 Sometimes the weak pawn can be an illusion and we can prove that with variations. 02:18.230 --> 02:26.150 First of all, if E5, let's say it isn't played, then Knight h4 and all of a sudden, well, Knight 02:26.150 --> 02:36.080 takes F5 is on to undermine the knight if G6 F4 and we can try and amplify the bishop like this. 02:36.290 --> 02:45.890 So this position takes E5 if Knight G4, Queen C one Knight takes e5 A3 and we try and break open that 02:45.890 --> 02:46.480 diagonal. 02:46.490 --> 02:55.850 This position is quite nice for White's and Queen G4 Queen G5 rather Bishop takes E4. 02:57.470 --> 03:00.800 Leaves one with a very dominating position here. 03:01.110 --> 03:07.520 After Rook takes a fake, rook takes F8 entry -86, 96. 03:07.820 --> 03:10.820 And yeah, White's just got a huge advantage here. 03:12.590 --> 03:16.420 And, you know, there's prospects to do all sorts of things. 03:16.430 --> 03:18.020 We got pressure, we got a weak pawn here. 03:18.020 --> 03:20.360 We got potentially four G for FFL. 03:20.510 --> 03:22.580 It's just been four one. 03:22.580 --> 03:22.850 So. 03:22.880 --> 03:23.540 E5 Yeah. 03:23.570 --> 03:24.770 Knight H for. 03:26.830 --> 03:29.520 And just to show the threat, if a59 takes F five. 03:29.530 --> 03:29.830 Yeah. 03:29.830 --> 03:33.550 So just, you know, the E4 nine is a target. 03:33.940 --> 03:37.000 So this variation is kind of critical with fall. 03:37.450 --> 03:45.310 But anyway in the game though it takes was played so this leaves the bishop nicely looking at G7 sea 03:45.310 --> 03:51.400 tanks and now Knight D six and now here really nice move. 03:51.430 --> 03:52.960 Guess what won't plays. 03:54.130 --> 03:56.080 So it looks as though, well, D5 is weak. 03:56.110 --> 03:57.790 Why did Alekhine do this? 03:58.420 --> 04:06.610 Well, my change for this bishop is lurking around being the kind of guardian of the white position 04:06.610 --> 04:08.290 and indirectly this pawn. 04:08.530 --> 04:17.320 We have Queen D7 If Knight takes D5 orders won't, do you think, at some points. 04:19.770 --> 04:21.000 Yeah, it has here. 04:21.040 --> 04:22.500 Rook takes D5. 04:23.790 --> 04:28.480 And then we can amplify the Bishop of Quirindi for the battery threatening chat mates. 04:28.500 --> 04:31.230 One is black do hair and also threatening D5. 04:31.290 --> 04:34.140 If knights have sex, then Bishop takes D5 check. 04:34.320 --> 04:40.140 So we're winning material and if Bishop takes the E5 instead, then wants the key move here. 04:42.730 --> 04:43.660 At some points. 04:44.590 --> 04:45.160 Yeah. 04:47.580 --> 04:49.560 Bishop takes off six is winning a piece. 04:51.330 --> 04:58.140 Not Route 65 here because this position has no def since I'm black, actually has a small edge. 04:58.140 --> 05:03.960 So now rook takes the E5 is not the way but in this case. 05:07.050 --> 05:09.900 Bishop takes offence undermines the bishop. 05:10.140 --> 05:11.640 If Knight takes, we're taking. 05:12.150 --> 05:12.990 Bishop, take 35. 05:12.990 --> 05:14.250 That's the way to win material. 05:14.370 --> 05:14.700 So. 05:14.700 --> 05:17.290 Okay, so it's all kind of it's immune. 05:17.310 --> 05:23.220 Diplomatic immunity at this point we have Quirindi seven, Bishop H free. 05:23.220 --> 05:28.800 And again, this pawn is immune actually, even though the bishop's now on this diagonal because well, 05:28.840 --> 05:35.460 black plate amplifying the bishop further really creating dance square weaknesses if Knight takes D5, 05:35.490 --> 05:37.050 can you see what won't plays here. 05:39.260 --> 05:41.510 You know, the power of the pin piece of -- is illusionary. 05:41.540 --> 05:44.380 Queen SACS E4 is spinning material. 05:45.650 --> 05:53.840 And if Bishop takes D5, yeah, Rook takes D5 here and then we get Queen takes E4 again, just winning 05:53.840 --> 05:54.290 material. 05:54.290 --> 05:57.740 This is just big for one huge point, huge position. 05:57.740 --> 06:03.820 So G sinks F3, C five and now Queen G five. 06:03.830 --> 06:06.680 Very direct play, very logical. 06:06.680 --> 06:10.760 This bishop is just doing so much damage to Black's position. 06:10.760 --> 06:14.870 It's just a major weapon here, a major attacking weapon. 06:15.890 --> 06:19.370 We have Queen G seven if night 65 hair. 06:22.850 --> 06:28.070 In fact Rook 65 is strong and then the follow up nine times G6. 06:28.580 --> 06:31.220 This just destroys the king. 06:31.220 --> 06:31.610 Really. 06:31.610 --> 06:35.720 If h takes ouch what is plan to Queen G seven. 06:36.380 --> 06:40.310 So yes, that is really devastating. 06:40.310 --> 06:41.450 Rook takes D5. 06:41.480 --> 06:45.650 It's the most devastating it seems, if 96. 06:48.040 --> 06:50.470 There's no E seven double check for a moment. 06:50.470 --> 06:51.790 So the king has to move. 06:52.710 --> 06:55.920 Queen f six chink and then 1965 is clean. 06:56.430 --> 07:01.800 Another way of playing it, though, instead of 65, even 90 6g6 immediately. 07:01.800 --> 07:02.830 96. 07:04.080 --> 07:04.890 96. 07:04.890 --> 07:06.060 F eight. 07:06.180 --> 07:09.240 Check here is good this position. 07:11.320 --> 07:15.670 Because if it's a freaking G2. 07:17.840 --> 07:18.650 And. 07:19.910 --> 07:22.250 One is going to be winning material. 07:22.250 --> 07:23.330 Whatever happens. 07:25.610 --> 07:30.500 If 95 broke, 65 is nice. 07:30.500 --> 07:35.750 This position leaves white as an example, a whole bunch of up. 07:38.470 --> 07:44.410 And if Rook eats, King takes this position, that's not enough compensation. 07:44.890 --> 07:46.000 A whole World Cup. 07:46.750 --> 07:47.110 So. 07:47.110 --> 07:47.740 Yes. 07:48.880 --> 07:51.010 So Queen G seven is played. 07:53.530 --> 07:54.460 Okay. 07:55.480 --> 07:58.750 Before 9d7. 08:01.290 --> 08:02.670 And now E-4. 08:03.240 --> 08:05.010 And this is really interesting. 08:06.720 --> 08:13.950 We have actually what seems to be a very clever move, 9/10 E4 rebounding against the pinna and hitting 08:13.950 --> 08:14.700 the queen. 08:16.470 --> 08:21.330 Now a really powerful move is played here, just amplifying this bishop, wanting to keep this bishop 08:21.330 --> 08:23.910 and finding one primary default thing. 08:24.080 --> 08:27.000 You know, sometimes you want to keep that bishop, so that's the clue. 08:27.030 --> 08:28.230 What would you play here? 08:33.670 --> 08:33.920 Yeah. 08:34.000 --> 08:35.050 Queen C one. 08:36.310 --> 08:37.800 This is really the strongest move. 08:37.810 --> 08:40.990 It creates just an enormous pressure on the diagonal. 08:44.440 --> 08:52.000 And if we just look at an alternative for a moment, if tanks, queen tanks, there is it takes this 08:52.000 --> 08:53.440 is better for white. 08:54.430 --> 08:56.560 But there's a bit of work to do. 08:56.740 --> 09:00.100 You know this position, it is clearly better for white as well. 09:01.330 --> 09:02.740 But there's work to do. 09:03.610 --> 09:05.800 It's not as crushing as Queen C one. 09:07.990 --> 09:09.580 So the thing is here. 09:11.310 --> 09:12.450 This position. 09:15.060 --> 09:17.290 There's something very nice about this position. 09:17.310 --> 09:18.720 Can you see what that is? 09:19.080 --> 09:20.070 Why it's playing. 09:22.460 --> 09:23.570 400 points. 09:24.110 --> 09:24.980 What would you play here? 09:28.040 --> 09:29.230 Yeah, there's a break. 09:29.240 --> 09:30.890 You know, destroying the shelter of the king. 09:30.890 --> 09:33.170 Bishop takes up five if King H. 09:33.200 --> 09:36.230 Well, King responded If G takes, then nine takes five. 09:36.240 --> 09:36.650 One is black. 09:36.650 --> 09:41.270 Do Queen G 697 wins the Queen. 09:43.070 --> 09:43.880 Queen H eight. 09:43.880 --> 09:50.060 There's no ice age six taking away the king escape squares and queen you five is checkmate Brutal. 09:51.140 --> 09:53.990 Yeah this this bishop can't be taken. 09:55.790 --> 09:56.150 So. 09:56.150 --> 10:00.620 KING H.A. now, Bishop Essex, strengthening that pawn huge pen. 10:01.670 --> 10:11.690 Bishop Isaacs We have a look at 5195, and now this wonderful finish for just encouraging 93. 10:13.050 --> 10:14.030 It's a really amplify. 10:14.030 --> 10:17.960 This bishop in spectacular style rotates. 10:17.960 --> 10:23.320 The free bishop takes the fray and now G4 with the big G5 and black actually resigned. 10:23.330 --> 10:27.710 This is all about bishop amplification in this game and the bishop about the counterpart. 10:27.770 --> 10:33.410 So black resigns here if H6 we just play G5 we're playing in with G5. 10:33.770 --> 10:35.600 This is really crushing stuff. 10:35.600 --> 10:37.820 Move the knight leave that nasty pin. 10:38.600 --> 10:41.180 Yeah, this is absolutely crushing. 10:42.080 --> 10:48.140 So G4 there's no real defensive G5 which is taking on Queens on C1 Thanks very much. 10:48.860 --> 10:50.600 So yeah, what a brutal game. 10:50.600 --> 10:54.020 This is really an emphatic game to say the least. 10:54.110 --> 10:56.990 What an emphatic victory you might think. 10:56.990 --> 10:57.670 Hold on. 10:57.680 --> 11:04.370 There is a question which looks in my mind though, about this, and let's just see for a moments what 11:04.370 --> 11:07.490 was the point of playing. 11:10.360 --> 11:11.580 E forehand and. 11:17.300 --> 11:19.580 Well, you know, at the moment. 11:22.390 --> 11:23.890 Five was defended. 11:23.890 --> 11:26.620 So what really happens with this E4 business? 11:27.220 --> 11:29.740 It seems we get a position where. 11:30.670 --> 11:31.120 Planks. 11:31.120 --> 11:37.240 Committing to nine takes E4 and the Queen steps way, which means Bishop takes F5 was actually ignited. 11:37.270 --> 11:39.520 It wasn't ignited here basically. 11:39.520 --> 11:47.350 So we get a kind of kind of tempo position where our queen's on C one now instead of on G five. 11:47.470 --> 11:53.320 So missing pawn, but our Queen's on C one protecting the bishop, very importantly protecting the bishop. 11:53.320 --> 11:56.860 And this is just such a punishing move. 11:57.620 --> 11:57.940 Yeah. 11:57.940 --> 12:03.550 Without the Queen being on G five, because then G takes, you know, our queen would be here. 12:03.550 --> 12:06.880 This is just a wonderful position of Bishop protected. 12:07.870 --> 12:08.950 Yeah, absolutely. 12:08.950 --> 12:10.630 Amazing stuff. 12:12.390 --> 12:13.220 And G5. 12:13.230 --> 12:14.580 You know, it looks just horrible. 12:14.580 --> 12:16.350 Bishop F five as well. 12:16.350 --> 12:23.160 I mean, so, yes, it's really interesting how this attack plays out and the amplification of the dot 12:23.160 --> 12:24.000 square bishop. 12:24.150 --> 12:30.030 So yeah, for me this is really an emphatic demonstration of the use of a bishop of our counterpart 12:30.030 --> 12:32.670 amplifying that bishop against the opponent's king. 12:34.710 --> 12:40.110 And everything seems to be mostly in service to this amplification strategy. 12:40.350 --> 12:40.740 Okay. 12:40.740 --> 12:43.200 I hope you enjoyed that and so much.
