WEBVTT 00:00.900 --> 00:01.590 Hi there. 00:01.620 --> 00:08.310 In this lecture, we see Jacinta to Caravaggio against Alexander Alekhine in the 1922 exhibition game 00:08.460 --> 00:17.550 E4 from Caravaggio we have E5 from Alekhine 9396, Bishop b5, The Royal of We have A6 Bishop a4 Knight 00:17.550 --> 00:26.280 have six White castles and now dissects the Steinitz defence deferred so this d6 move White now volunteers 00:26.280 --> 00:27.300 the light Squire Bishop. 00:27.300 --> 00:33.270 Now this is quite often a great ingredient of an attacking strategy. 00:33.270 --> 00:40.380 We have this emphatic extreme imbalance where White doesn't have a light at square bishop and we really 00:40.380 --> 00:42.780 want to use this bishop to checkmate the opponent's king. 00:42.780 --> 00:46.460 Basically, that would be a great use of using this pressure. 00:46.470 --> 00:50.580 If we can get on to this diagonal and be involved in this diagonal. 00:50.580 --> 00:54.210 Now, that's a fantasy dream, but it's made possible. 00:54.210 --> 00:57.660 We do have the ingredients here, a key ingredient. 00:57.660 --> 01:02.880 So bear this in mind, the bishop of our counterpart, even like the Morphy Opera game, there was a 01:02.880 --> 01:04.020 bishop of our counterpart. 01:04.020 --> 01:11.940 When Morphy's opponents gave them, they gave up their alliance and Morphy destroyed them on dance on 01:11.940 --> 01:13.200 the light squares later. 01:14.640 --> 01:17.520 So basically, yeah, we have that imbalance. 01:17.520 --> 01:18.990 So D4 is played. 01:19.020 --> 01:20.400 Knight takes E4. 01:20.430 --> 01:29.670 This clears the path actually for the bishop we have rookie one and now f5d takes e5 D four and now 01:29.670 --> 01:32.130 94 we have Bishop C5 in response. 01:32.130 --> 01:35.250 The knight's not going anywhere here C5 protecting Knight. 01:35.250 --> 01:40.260 If Knight takes C6, Bishop takes F to Czech Bishop takes E1. 01:40.260 --> 01:41.490 Thanks very much. 01:41.520 --> 01:42.420 The Queen. 01:42.720 --> 01:45.480 If White takes the Queen, there's nothing left to check. 01:45.900 --> 01:47.610 And that's absolutely winning for black. 01:47.790 --> 01:51.810 So C4 is needed and now just castling. 01:51.810 --> 01:55.800 We have a full oak. 01:56.250 --> 02:06.360 If three Knight G5 this position Bishop takes G5 queen thanks G5 White can play like this with b4. 02:06.990 --> 02:14.010 And there's a point here that actually the two nights are not entirely terrible against the two bishops. 02:15.790 --> 02:19.150 So let's say a591836 is possible. 02:19.150 --> 02:22.010 8/8 B Queen 65 check. 02:22.180 --> 02:24.760 And this position has a small edge. 02:24.970 --> 02:31.900 So in fact here instead of a five though, I mean yeah, if Bishop be seven, that's a bit ambitious. 02:31.900 --> 02:35.050 Because of 96 and losing the exchange, it's just too much. 02:35.350 --> 02:37.660 So yeah, it is a kind of tricky scenario. 02:37.870 --> 02:39.220 Triggered off with a three. 02:39.250 --> 02:46.480 So just to recap, if it gives up both bishops essentially and B for this looks like a position where 02:46.480 --> 02:48.340 Y is trying to undefined this pass pawn. 02:48.340 --> 02:53.950 So the bishops kind of kept at bay on C eight and we can see that yeah, this is an interesting position 02:53.950 --> 02:59.110 for white to play from move the two knights but okay F four is played. 03:00.070 --> 03:02.530 Now this doesn't do anything for this diagonal. 03:02.530 --> 03:09.160 This dream of this diagonal is kind of hasn't been blocked at least we have Queeny eight, Bishop E 03:09.380 --> 03:15.340 and now Bishop six And there is a dream here of C5 and using the bishop on the diagonal. 03:15.340 --> 03:19.900 And I've actually used this in many online games of great success. 03:19.900 --> 03:25.090 When I've got a bishop like this, I want to use it on that diagonal and Alekhine is starting to clear 03:25.090 --> 03:25.960 the way and look. 03:25.960 --> 03:29.320 Look, the dream is becoming true to every rook. 03:29.320 --> 03:31.750 D eight Queen C two now C five. 03:31.750 --> 03:39.730 He wants to maybe push for D4 later, might be free and now C4 as possible here might be D for y doesn't 03:39.730 --> 03:44.010 want to play Bishop takes B6 because then black will insert c takes B3. 03:44.020 --> 03:44.680 Thanks very much. 03:44.680 --> 03:46.690 Hitting the Queen and being a piece up. 03:47.140 --> 03:50.800 So the knight goes back C five point E two. 03:50.830 --> 03:53.860 Now at least we have this potential for D4. 03:53.890 --> 04:02.410 So bear that in mind and we have a potential focal point on G2 so our Queen could get involved at G6 04:02.410 --> 04:07.540 For this bishop in particular, you can see that G2 is of special interest. 04:07.540 --> 04:09.940 The E4 at some point is a special interest. 04:10.090 --> 04:11.770 Queen C six is played. 04:12.310 --> 04:13.870 Why not Queen G6 and one go? 04:13.870 --> 04:19.960 Well, the engines actually prefer Queen G6 and one go and if be free H sex. 04:20.810 --> 04:22.910 As an example, this position. 04:23.630 --> 04:25.040 KING seven. 04:25.130 --> 04:29.780 KING H1 and black sedan, double the pawns and A5. 04:30.560 --> 04:33.120 This seems as though it's pleasant enough for black. 04:33.140 --> 04:39.410 If White's careful, there shouldn't be a major immediate disaster, but black is actually significantly 04:39.410 --> 04:40.310 better here. 04:40.850 --> 04:42.140 The pawns have been doubled. 04:42.140 --> 04:45.230 And in fact, you know, there's a backward pawn target here. 04:45.260 --> 04:49.880 Black can actually play on the queenside, and the knight on E4 is just fantastic. 04:51.350 --> 04:56.980 If, for example, Queen Lee won, you know, Black could put pressure on things and even Knight Sexy 04:56.990 --> 04:59.520 three becomes possible for this kind of tactic. 04:59.540 --> 05:02.820 This is just fictional just to show the bishop has really good beef. 05:02.840 --> 05:05.150 These are big target Black's burner positioning. 05:05.390 --> 05:13.880 But anyway, instead of Queen C6 instead of Queen G6 rather in one go, Queen C6 is played. 05:15.410 --> 05:17.080 So this is interesting. 05:17.090 --> 05:22.730 We have Rook 81 and H thinks Rook f1 are now king. 05:23.570 --> 05:26.150 This and waiting around each one. 05:26.330 --> 05:30.280 Now an alert button should be in one's head here. 05:30.290 --> 05:33.590 The bishop is actually X-raying the king. 05:34.070 --> 05:36.290 And we do have Queen G6 now. 05:38.870 --> 05:43.430 Eight five is also an interesting positional move if B3 ever again. 05:43.430 --> 05:50.270 You know we can play like this and we've kind of restrained with A5 that pawn Also we got Bishop A6 05:50.270 --> 05:53.390 as a resource new resource which could be useful. 05:53.390 --> 05:54.790 So bear that in mind. 05:54.800 --> 06:00.350 But the Queen G6 was played nine e.g. one, Queen H five and now. 06:01.070 --> 06:06.800 Yeah, this is an interesting moment of problem. 06:07.220 --> 06:08.660 Can you see what black is first? 06:08.660 --> 06:12.460 Then start off with if be free. 06:12.470 --> 06:14.300 Let me test you for ten points. 06:14.300 --> 06:15.230 What would you play? 06:15.980 --> 06:18.140 Yeah, the game would end with Knight G free. 06:18.140 --> 06:18.860 Checkmate. 06:19.100 --> 06:23.600 So my times free is understandable to parry Knight G free for that. 06:23.840 --> 06:28.640 It turns out here 92 is also another way. 06:28.670 --> 06:38.240 Knight one to E, two to Parry Knight G free and here if a5 kanji one Bishop c6 be free. 06:38.270 --> 06:43.370 It's a position and the bishop can actually use this diagonal with Bishop B5. 06:44.240 --> 06:51.710 We can put our mating plans on hold and this situation is going to be kind of favorable, winning the 06:51.710 --> 06:52.820 exchange as an example. 06:52.820 --> 06:55.910 So what if it doesn't want to give up the exchange? 06:55.910 --> 07:03.200 If Rook B won, then there are interesting tactics here based on this Bishop X rang. 07:03.710 --> 07:09.380 Actually, there's there's a remarkable tactic in this position just to show the bishops also dangerous 07:09.380 --> 07:13.460 on this diagonal, creating opportunity for itself for 100 points. 07:13.460 --> 07:14.390 What would you play here? 07:14.420 --> 07:15.560 This is just fictional. 07:17.800 --> 07:21.340 But we have actually got bishop, the phrase resource. 07:22.970 --> 07:30.650 If Queen 63 C4 and the Queen has to leave the bishop on E3 and in this position is just great for black. 07:31.580 --> 07:33.130 Look at all the potential here. 07:33.140 --> 07:34.610 White's ready tied down. 07:35.900 --> 07:36.470 Okay. 07:36.530 --> 07:40.490 And we could even consider just winning the exchange if we want. 07:40.490 --> 07:44.510 But just leaving white paralyzed is also pretty good. 07:45.980 --> 07:46.760 So. 07:46.760 --> 07:47.480 Okay. 07:48.110 --> 07:53.810 Anyway, noise tree free though, leads to a situation which is very, very bad. 07:53.810 --> 07:56.260 So guess what black player said. 07:56.270 --> 07:57.710 What does play here? 08:00.460 --> 08:00.650 Okay. 08:00.760 --> 08:02.610 He does actually open up the bishop. 08:02.620 --> 08:04.300 The dream is really coming true now. 08:04.300 --> 08:07.600 The bishop is starting to get a view on the King Sea tanks. 08:07.600 --> 08:08.260 Sea tanks. 08:08.260 --> 08:11.860 And why it makes this a total, unmitigated disaster. 08:11.860 --> 08:15.370 By playing Bishop takes D4, it makes things a lot worse. 08:15.370 --> 08:22.150 Bishop G one had to be played, and in which case in this position, G5 five is interesting. 08:23.230 --> 08:27.130 If tanks H tanks, we could try and use this pawn to fork the rooks. 08:27.130 --> 08:29.050 But g4 e seven. 08:31.230 --> 08:33.510 It's a very tricky scenario here. 08:34.260 --> 08:43.140 If we look at Bishop takes D4, Czech rook takes D4 road takes d4 G takes H3, we can see the damage 08:43.170 --> 08:44.850 being done to White's king. 08:45.090 --> 08:50.280 Bishop text e4 964 Black could end up crashing through like this with Rook. 08:50.610 --> 08:52.440 It's just a very, very strong position. 08:52.680 --> 08:53.430 I woke up. 08:53.430 --> 08:55.200 This pawn isn't that significant. 08:56.700 --> 08:58.080 So let's say E seven. 08:58.080 --> 08:59.400 Let's go E seven. 09:00.030 --> 09:04.200 Black has to tread a bit carefully here and play D3. 09:04.890 --> 09:08.080 If G takes H3, this is a different scene altogether. 09:08.100 --> 09:09.030 Bishop takes D4. 09:09.030 --> 09:10.230 Czech rook take. 09:10.680 --> 09:19.200 Bishop takes D4, Rook takes the E4, H takes G2, Czech Queen G2 B eight. 09:19.230 --> 09:23.490 There's enough for White's do here taking out that rook and rook g1. 09:24.120 --> 09:28.920 This could just go into an equal end game with simplification like this. 09:29.370 --> 09:31.640 It just goes into a rock and pawn ending. 09:31.650 --> 09:33.750 So black has to be careful. 09:33.750 --> 09:35.250 This would be just about equal. 09:36.700 --> 09:38.980 But with D3 in this scenario. 09:39.130 --> 09:42.400 So this is where best play with Bishop D1 with D3 here. 09:43.300 --> 09:45.330 Queen St C4 G Tanks A3. 09:45.340 --> 09:46.540 This is very different. 09:47.110 --> 09:48.580 Rook takes F8. 09:49.900 --> 09:54.660 And we can see that this position of the G tanks H free, there's no G five. 09:54.670 --> 10:00.970 You can see the power of these bishops that that one that bishop is really seeing the kingpin in the 10:00.970 --> 10:11.080 every night rook takes D three 9/10 F4 is just it's going to be a crushing 95 check from the bishop 10:11.620 --> 10:13.870 wins the queen next. 10:13.870 --> 10:17.860 We could even slip in a couple of checks first and then when the queen. 10:18.100 --> 10:21.850 So yeah, there are fascinating scenarios essentially with Bishop G. 10:21.850 --> 10:22.390 One. 10:22.780 --> 10:26.950 This is the only way for White to play on in this position. 10:27.100 --> 10:33.400 So basically in a nutshell to try and use the e pawn to try and hijack these diagonals off the G5. 10:33.400 --> 10:36.940 So yeah, G5 has some costs associated with that. 10:37.540 --> 10:40.120 But overall it's worth playing here. 10:40.510 --> 10:43.660 So this this is a critical attacking pattern. 10:43.660 --> 10:45.970 Where are kings getting exposed? 10:45.970 --> 10:49.000 But if we play our cards right actually accurately, we're okay. 10:49.270 --> 10:51.130 But this didn't happen. 10:51.130 --> 10:55.330 So White just basically capitulated with bishop tanks. 10:55.330 --> 10:59.680 D form makes things a lot worse and they're going to just take us on D4. 10:59.710 --> 11:00.610 He's got a combination. 11:00.670 --> 11:03.400 He's in combination mode, in combination mode. 11:04.480 --> 11:10.870 So 964 is just as a disastrous but I don't want to spoil the combination just yet. 11:12.070 --> 11:20.770 We have rotates the E4 964 Now here's the key move which is often used for many puzzles. 11:20.770 --> 11:23.020 We're in a checkmate puzzle now, basically. 11:23.650 --> 11:26.230 So what would you play here with Black? 11:26.800 --> 11:29.530 So this is the culmination of this bishop. 11:31.600 --> 11:35.770 A bishop about a counterpart pointing at the king basically through x ray. 11:36.490 --> 11:38.300 How do we celebrate this? 11:38.320 --> 11:43.390 How do we amplify the mating pattern that might exist? 11:43.390 --> 11:44.620 Mating patterns? 11:44.770 --> 11:45.760 What would you play for? 11:45.760 --> 11:46.900 200 points? 11:50.950 --> 11:51.330 Okay. 11:51.340 --> 11:52.270 The beautiful queen. 11:52.270 --> 11:52.570 Thanks. 11:52.570 --> 11:53.320 Inch very. 11:55.130 --> 11:58.280 The dreams really, really coming true to its full extent. 11:58.820 --> 12:02.740 So if White just ignores this, fine, we're just peace up. 12:02.750 --> 12:04.130 No problem winning. 12:04.490 --> 12:06.080 So G tanks ain't free. 12:06.080 --> 12:07.590 And the point is here. 12:07.610 --> 12:08.600 What would you play? 12:08.660 --> 12:10.730 Which check? 12:11.920 --> 12:13.090 Think carefully. 12:15.040 --> 12:16.990 Okay, I have to check. 12:16.990 --> 12:17.590 Double check. 12:17.620 --> 12:20.880 The king has to move because it's a double check. 12:20.890 --> 12:22.660 Kings have to move on a double check. 12:23.140 --> 12:26.770 King G want Knight takes H three is checkmate 12:29.200 --> 12:33.310 glorious A glorious celebration of the bishop without a counterpart. 12:33.310 --> 12:39.970 You can see that ingredients picked up in the opening phase of this game and how it can be a vicious 12:39.970 --> 12:43.960 tactical ingredient as vicious as a form pawn, in my view. 12:44.060 --> 12:44.980 Love the form balls. 12:44.980 --> 12:52.000 But yeah, it's one of my favorite concepts and is also another one I've observed heavily in studying 12:52.000 --> 12:58.570 neural network games that sometimes and the neural network engineers are often prepared to sacrifice 12:58.570 --> 13:03.430 one or two or even three pawns to amplify a bishop of our counterpart. 13:03.460 --> 13:04.390 Now in this game. 13:04.390 --> 13:09.850 Yeah, there was some very interesting moves and the bishops working together in many variations. 13:09.850 --> 13:14.890 So we see that, yeah, this general plan of trying to liberate the bishop across the diagonal is one 13:14.890 --> 13:16.930 that I've won so many games with as well. 13:17.260 --> 13:25.810 It's like people are oblivious to this part of evaluating positions. 13:26.080 --> 13:30.390 The more classic thing talked about is having the bishop pair. 13:31.360 --> 13:37.810 But yeah, Bishop without a counterpart to me is a fantastic, glorious, exciting attacking ingredients 13:38.320 --> 13:40.900 and the whole plan, you know, liberating. 13:40.900 --> 13:45.340 Later, with the fall, we're setting the scene for a liberation with the fall. 13:45.820 --> 13:51.460 So it made this significantly worse because, yeah, the Queen's looking at Queen saying free these 13:51.460 --> 13:53.440 outrageous forcing moves. 13:54.430 --> 13:59.710 Even if they don't work here, they demonstrate the pressure that White is up against and has to continually 13:59.710 --> 14:02.170 calculate these crazy forcing moves. 14:02.170 --> 14:08.440 And if White slips up, then all of a sudden this crazy forcing move is working in a key position. 14:08.440 --> 14:09.580 It's working here. 14:10.840 --> 14:12.820 That's another thing about attacking chess. 14:13.510 --> 14:18.910 This awareness of concrete forcing moves, you know, there's going to be a slip up somewhere. 14:18.980 --> 14:20.790 Actually, you know, it could work out. 14:20.790 --> 14:27.070 So you've got to be on the lookout all the time for checking out your forcing moves, not to miss that 14:27.070 --> 14:28.300 golden opportunity. 14:28.570 --> 14:29.830 So Queen takes sanctuary. 14:29.830 --> 14:32.770 Anakin is not missing the golden opportunity at all. 14:32.770 --> 14:39.490 Here He plays it with spectacular checkmate to be celebrated many, many years later. 14:39.490 --> 14:41.920 This nice, cute checkmate combination. 14:41.920 --> 14:45.130 But it's the build up we're interested in, Winston and the ingredients. 14:45.130 --> 14:47.680 We want to see the magic behind this kind of thing. 14:47.680 --> 14:49.540 How it's actually arranged. 14:49.930 --> 14:50.710 Okay. 14:51.380 --> 14:52.390 Have you enjoyed this? 14:53.200 --> 14:53.920 That's a much.
