WEBVTT 00:01.020 --> 00:01.830 Hi there. 00:01.860 --> 00:07.380 In this lecture, we see Alexander Alekhine against César Morosi in 1951. 00:07.380 --> 00:17.400 The blood tones we have deformed from Anaconda five from Rossi c4 e6 9c3 Knight f6 Bishop G five Bishop 00:17.410 --> 00:18.150 E7. 00:18.240 --> 00:19.770 So the Queen's Gambit declined. 00:19.770 --> 00:21.030 Orthodox Defense. 00:21.390 --> 00:28.020 We have a free night bd seven nights f free Black Castles Rook c one. 00:28.560 --> 00:31.320 So this wants to try and catch detail in one go. 00:31.320 --> 00:36.180 Not that black will play D takes in one go, but black will play another move which might not be ideal. 00:36.180 --> 00:41.160 So H six is played Bishop age four and now C6 so this is not ideal. 00:41.790 --> 00:43.900 And now the bishop moves. 00:43.900 --> 00:46.350 So not mining detailed C4 hair at all. 00:47.430 --> 00:52.800 We have a6y consoles D tank, C4, Bishop tank C4. 00:52.800 --> 00:53.640 Now C5. 00:53.640 --> 00:58.860 This is a very logical play from Black A4 Queen A five, so that's logical as well. 00:59.520 --> 01:06.030 Queen E two And here it seems as though Y is being saddled with an ice queen's pawn. 01:06.060 --> 01:08.760 C tanks D4 and Queen does play. 01:08.790 --> 01:10.110 E takes d4. 01:11.250 --> 01:16.290 We have Knight Be6, Bishop D free Bishop D seven. 01:17.160 --> 01:23.970 So Black has a potentially nice blockade on the D five square and you might wonder about these possessions. 01:23.970 --> 01:25.470 They seem a bit fragile. 01:25.500 --> 01:28.110 We see 95, which kind of weakens d4 a bit more. 01:28.110 --> 01:31.860 Actually we have rook after eight not Minding Knight takes these seven at all. 01:33.360 --> 01:38.460 If it takes these seven I mean let's look at this Black has a lot of pressure on D4 and a beautiful 01:38.460 --> 01:45.870 blockade square and even the possibility maybe of taking out A4 at some point or Queen H five. 01:47.010 --> 01:51.600 I mean there are various possibilities here for Black, but it looks as though it hasn't got much attacking 01:51.600 --> 01:52.350 potential. 01:52.530 --> 01:58.770 So Alekhine actually creates a position with interesting attacking potential through the concept basically 01:58.800 --> 02:03.930 of trading off material for king safety, the opponent's king safety, your own material for king safety 02:03.930 --> 02:05.580 and isolated material. 02:05.580 --> 02:10.500 Isolated Queen's one, which is going to tie way up to try and defend this. 02:10.500 --> 02:16.230 We have A4 anticipating a potential sacrifice of this pawn. 02:16.230 --> 02:20.340 So this is really a nice attacking move and attempt. 02:20.340 --> 02:23.670 It might not be theoretically all that correct. 02:24.810 --> 02:28.080 We have Bishop E so D4 looks to be hanging. 02:28.080 --> 02:30.960 So this is a critical junction point. 02:31.470 --> 02:36.750 Now the decision here is maximising win probability based on attack. 02:38.010 --> 02:45.600 Alekhine's move is offering the deep Knight G4 to try and create some damage around the opponent's king. 02:46.380 --> 02:50.070 If Bishop F2 is plays, let's take this as an example. 02:50.070 --> 02:52.530 Black could use the lovely blockade square. 02:53.430 --> 02:55.170 And what does white have here? 02:55.170 --> 02:59.310 You know, this doesn't seem very nice. 02:59.310 --> 03:00.480 It's not in harmony. 03:00.480 --> 03:06.240 The pieces in pawns are not in ideal harmony here, especially this bishop on the same color as this, 03:06.240 --> 03:07.200 these pawns. 03:07.470 --> 03:10.800 And for example, Knight C for Queen 87. 03:10.800 --> 03:13.770 Bishop Geoffrey Black does have a slight edge here. 03:15.930 --> 03:19.320 I mean, it's not completely busted, but it seems more comfortable for black. 03:19.320 --> 03:22.530 So anyway, Knight G4 though, is very interesting. 03:22.620 --> 03:24.690 Black should have kept very calm here. 03:24.690 --> 03:29.310 Black kind of accepted this virtual gambit of Alekhine taking on D4. 03:30.270 --> 03:37.170 And so there is an exchange of structural damage around the opponent's king instead in this position. 03:37.170 --> 03:39.810 Knight B5 would have been interesting. 03:40.980 --> 03:43.230 So, for example, let's take a violent attempt. 03:43.260 --> 03:45.750 1986 check G tanks. 03:45.750 --> 03:48.150 H six, F five. 03:48.150 --> 03:49.710 This isn't such a big deal. 03:49.740 --> 03:55.470 Black does have resources like Queen B six, not just hitting D4 but also supporting E6. 03:55.980 --> 04:00.150 So F takes Queen takes E6 is the safest. 04:00.150 --> 04:02.130 Try and get the Queen's exchanged off here. 04:02.220 --> 04:03.750 So I'm taking on D4. 04:04.050 --> 04:11.760 This position can go back and and look at the four here and it ends up being significantly better for 04:11.760 --> 04:12.180 black. 04:12.180 --> 04:14.520 Maybe a bit of inconvenience, but not too much. 04:14.520 --> 04:18.600 This is overall it's going to be better for black, this position, this type of position. 04:20.190 --> 04:23.190 So okay, you know Knight B five was better. 04:23.190 --> 04:30.930 Knight takes G4 doesn't really work because the bishop tanks E seven and the rook and hanging. 04:30.930 --> 04:39.480 And the thing is here for example, there's B4 and you know the Queen's could come off, Bishop takes 04:39.480 --> 04:42.510 the eight that's just winning material for White's. 04:42.900 --> 04:44.850 So yes, that doesn't look. 04:46.460 --> 04:49.490 Too promising at all these kind of situations. 04:50.390 --> 04:56.090 And there's also, you know, additional situations if if the route moves, there are resources like 04:56.090 --> 05:01.220 bishops C five, for example, for B for potentially trapping the queen and with the knights still hanging. 05:01.490 --> 05:05.270 You know, this this kind of thing doesn't look very clever for black. 05:05.540 --> 05:11.530 So, okay, so no takes G4 is out is terrible, but Route 64 is also not entirely grain. 05:11.540 --> 05:13.460 We have Bishop takes offense. 05:14.990 --> 05:18.230 This is an interesting situation now. 05:18.230 --> 05:27.320 Structural damage has been incurred 94 hitting f6 rook 88 here. 05:27.500 --> 05:32.300 If we look at F5 for the moment, what happens here on F5 you might ask? 05:32.300 --> 05:42.650 Well my F6 check and here Queen F3 looking at D4 Queen thanks A4 say why it has resources here like 05:42.650 --> 05:47.060 Bishop takes a five which should guarantee a draw by perpetual. 05:47.090 --> 05:54.470 The king is exposed somewhat and for example King G 7.85 check and then going back big Frac Queen St 05:54.500 --> 05:55.010 H six. 05:55.010 --> 05:57.890 So the king doesn't want to be drawn out. 05:57.890 --> 06:01.880 And so this this is likely to be just the drawback perpetual check in reality. 06:02.420 --> 06:06.810 So anyway Rook 88 was played Knight takes f6 check. 06:06.830 --> 06:11.600 So King Safety has been affected by sacrificing that D pawn. 06:12.020 --> 06:18.530 And when we talk about trade offs between material and king safety, the four major elements many chess 06:18.530 --> 06:25.310 websites agree on for evaluating any position king safety material, pawn structure and piece activity. 06:25.340 --> 06:30.320 KING Safety material are very interesting trade offs to trade off your own material to reduce the opponent's 06:30.320 --> 06:32.210 king safety, like in this example. 06:33.320 --> 06:38.780 Now, if King G7, what would you say is a good move in this position? 06:38.780 --> 06:41.090 There's actually a very powerful move in this position. 06:41.180 --> 06:44.720 Again, we can further trade off material potentially. 06:44.720 --> 06:46.790 So for 100 points, what would you play in this variation? 06:46.790 --> 06:47.810 This didn't happen. 06:47.810 --> 06:50.960 King F8 was played, but here, what would you play? 06:56.470 --> 06:56.850 Okay. 06:56.860 --> 06:58.870 F five would be actually rather strong. 07:00.280 --> 07:02.680 Yeah, it's it's just it's very, very dangerous. 07:03.100 --> 07:05.410 Tanks D free tanks check. 07:05.410 --> 07:06.310 And then queen tanks. 07:06.310 --> 07:07.150 D free. 07:08.110 --> 07:08.470 Yeah. 07:08.470 --> 07:13.450 It's, it will be very, very dangerous for black to take on f6 here. 07:15.890 --> 07:21.380 So the king is being pulled open somewhat and. 07:22.600 --> 07:23.770 Okay, so. 07:25.630 --> 07:33.460 If we take this a bit further as well, though, if King F eight, F takes E six, it takes F seven. 07:33.730 --> 07:37.630 There's another nice, cute, fancy variation I want to show you. 07:37.660 --> 07:43.360 So if black doesn't give up a rock, say Black doesn't give up a rock here with Rook. 07:43.400 --> 07:45.250 If, say, black plays queenly sex. 07:45.280 --> 07:48.070 Can you see what knock out black hair in this position? 07:50.080 --> 07:51.660 We quite convincing. 07:51.990 --> 07:53.310 Yeah, well, we've got choice. 07:53.310 --> 07:54.280 We can even play Queenie ain't. 07:54.300 --> 07:56.280 But actually even more correct. 07:56.280 --> 07:58.740 Is Queen four even more accurate? 07:59.340 --> 08:02.640 So heading for that, Queen eight, you know, checkmate. 08:04.650 --> 08:07.770 So, och, they're very dangerous situations. 08:07.770 --> 08:17.130 Basically, if the King's brought out here because of five and peeling open the king like this is just 08:17.130 --> 08:22.830 there's a wolf of attacking potential here in this kind of situation. 08:22.830 --> 08:30.750 See black hair plays Bishop takes F seven because if rook takes the three, we can rule that out and 08:30.750 --> 08:32.850 think Queen, that's pretty nasty. 08:34.230 --> 08:36.030 So Bishop takes seven. 08:36.510 --> 08:40.980 What do you think is a really strong move in this position? 08:46.590 --> 08:50.190 Not many pieces of black garden e seven hair. 08:50.190 --> 08:50.860 That's a clue. 08:50.880 --> 08:54.920 So there's a way of actually getting into E seven with the queen. 08:54.930 --> 08:56.610 Can you say, well, that it's 100 points. 08:59.310 --> 09:05.250 Potentially with great effect, we can kick off with tanks f seven tank sacrificing material around 09:05.250 --> 09:06.570 material for the opponents. 09:06.570 --> 09:11.460 King Safety here rook have one check and once we get in Queeny seven, that's devastating. 09:11.460 --> 09:17.850 Then we've got killer common squares while nice cool killer common squares like not their bishop 87 09:18.300 --> 09:19.350 and the Queen 97. 09:19.350 --> 09:22.170 So King Jane Queen 87 one be checkmate. 09:22.260 --> 09:24.990 So just to recap that, let's have an action replay. 09:24.990 --> 09:32.220 King comes out play after takes E6 check from the rook E takes F seven is devastating because there's 09:32.220 --> 09:34.500 nothing really covering the entry point E seven. 09:34.500 --> 09:40.890 It's only the king and we can actually get that entry point with check or we've checked while these 09:40.890 --> 09:42.990 pieces are just frozen in time. 09:42.990 --> 09:45.750 We're getting all these tempos and these pieces are just frozen. 09:45.750 --> 09:46.950 They're like statues. 09:46.950 --> 09:55.380 So, yes, coming back to the game, then King F8 was played and we have 97 check. 09:57.300 --> 09:58.320 And here. 09:58.350 --> 10:00.600 Yeah it's it's incredibly. 10:03.060 --> 10:04.920 Dangerous hair. 10:07.170 --> 10:08.970 This is very interesting. 10:09.060 --> 10:17.040 But there's also, you know, F5 is also interesting for rotates f tanks this position with E seven 10:17.040 --> 10:22.070 check we can win material, lots of material and also do a forklift. 10:23.340 --> 10:25.380 So this kind of situation is diabolical. 10:25.380 --> 10:26.040 For black. 10:26.040 --> 10:27.750 We just winning, not zero. 10:28.110 --> 10:28.380 So. 10:28.380 --> 10:29.940 Okay, nice H seven check. 10:29.940 --> 10:31.890 The king went to E seven. 10:31.890 --> 10:36.960 So filling that was safer rather than this side of the ball where there's all sorts of things going 10:36.960 --> 10:40.920 on, like potentially rook lifts or the queen coming in with Shaq. 10:41.370 --> 10:42.930 There's a lot of dangers there. 10:44.690 --> 10:45.470 So. 10:45.890 --> 10:51.860 Okay, so we have King E seven and now F five offering the DX Free Bishop. 10:51.860 --> 10:53.630 This is absolutely amazing stuff. 10:53.630 --> 10:55.640 Rook 8d6 is played. 10:55.850 --> 11:03.020 If Rook takes the free here, there's simply F six actually getting the king to disconnect the rooks 11:03.020 --> 11:05.780 and then we can take on D three with big advantage. 11:07.310 --> 11:11.540 So Rook 8d6 was played trying to keep the rooks protecting each other. 11:12.140 --> 11:19.580 We have now b4 this is trying to get access to E5. 11:19.850 --> 11:22.040 So it's interesting an echo of what we've seen previously. 11:22.040 --> 11:26.060 Trying to get access to to squares with the Queen is very important. 11:26.060 --> 11:29.600 So Queen thanks b b for that weakness of the last move. 11:30.380 --> 11:33.830 It seems like these micro details, they're super significant. 11:37.050 --> 11:38.190 Okay, so this is. 11:39.630 --> 11:41.610 Very, very tricky. 11:43.800 --> 11:46.230 On a move like Queen D five. 11:47.130 --> 11:48.040 Well, queenly five. 11:48.060 --> 11:53.060 Concretely, there's there are ways of breaking this position. 11:53.070 --> 11:56.160 So here a key move would be Rook c five. 11:56.160 --> 11:58.730 That is one of the best moves here just to win the queen. 11:58.740 --> 12:00.420 Basically, Rook takes the three. 12:00.720 --> 12:07.770 We could take the queen off here, take on E6, and this should be very pleasant for white. 12:07.980 --> 12:11.040 White overall is doing very well here. 12:11.880 --> 12:13.360 So Queen H for check. 12:13.410 --> 12:18.480 This is just a fictional example and we could start checking the king and winning material. 12:18.960 --> 12:24.060 So this is thought to be clearing up here with advice for my career advice for white. 12:24.180 --> 12:27.480 So anyway, so Queen D five wasn't trained. 12:27.480 --> 12:35.520 We have Queen St before, which relinquishes E5 and pounces into E5, not worrying about the D three 12:35.520 --> 12:40.740 Bishop and Black plays 97 hand. 12:42.370 --> 12:45.910 If Rook takes the fray, can you see acute checkmate. 12:47.700 --> 12:51.540 In basically two gentlemen to two. 12:52.320 --> 12:52.530 Quick. 12:52.530 --> 12:53.130 One, two. 12:53.180 --> 12:53.520 There's. 12:54.030 --> 12:55.200 I'm about to reveal. 12:55.540 --> 12:57.420 Let's try and work out the quick checkmate. 12:58.590 --> 13:00.240 It's Queen F six, Jack. 13:00.240 --> 13:02.940 And that drives the king away from the F eight square. 13:02.940 --> 13:06.390 So that's a new opportunity to use a new resource. 13:06.690 --> 13:07.840 Fate is checkmate there. 13:07.860 --> 13:08.910 That's pretty cute. 13:09.540 --> 13:10.740 So 97. 13:10.740 --> 13:15.540 Yes, 95 was actually more solid and perhaps just an even position, actually. 13:15.720 --> 13:16.140 Yeah. 13:16.360 --> 13:19.870 It's very rich games with resources for both sides by 95. 13:19.890 --> 13:20.040 Yeah. 13:20.040 --> 13:26.670 It seems as though this might be stable enough for black, but 97 was played queen and now a total disaster 13:26.670 --> 13:30.870 Move is played Rogue takes the frame. 13:30.900 --> 13:32.040 This shouldn't have been played. 13:32.050 --> 13:35.130 80 takes is not so hot either. 13:35.460 --> 13:39.570 This position is going to be better for white. 13:39.590 --> 13:41.580 One's going to be winning material as an example. 13:41.580 --> 13:43.990 But Rook C6 is stubborn. 13:44.010 --> 13:45.690 This becomes a bit murky. 13:45.840 --> 13:50.620 It is possible for White to get an advantage, but, you know, it's a lot of work. 13:50.640 --> 13:52.080 You know, this kind of thing. 13:52.440 --> 13:57.640 And once just a pawn down by engine suggests this is slightly better for white. 13:57.660 --> 14:00.150 But in the game we have a total disaster move. 14:00.150 --> 14:02.010 Rook takes the phrase, So this is fun. 14:02.190 --> 14:06.060 So why on earth is this winning for white? 14:06.090 --> 14:07.080 Can you work out? 14:07.140 --> 14:13.410 Tactics are really important tactical combinations for the masters of attack. 14:14.340 --> 14:16.470 So I hope you can work it out here. 14:17.200 --> 14:21.330 This is quite rewarding, in my view, to work out the false checkmate. 14:22.980 --> 14:23.760 Okay. 14:26.770 --> 14:29.790 It's actually I'm about to roll that f6 check. 14:29.800 --> 14:30.460 You might wonder. 14:30.730 --> 14:31.660 You know what? 14:31.810 --> 14:32.740 What about King Lear? 14:32.860 --> 14:34.720 Can you see what happens on King The eight? 14:37.540 --> 14:40.110 Yeah, we can actually take on here. 14:40.780 --> 14:42.400 Taking the King away from Kate. 14:42.400 --> 14:44.230 And she is actually checkmate. 14:44.230 --> 14:47.440 The pawn is holding King Escape square E seven. 14:48.220 --> 14:53.800 And in the event of night tanks have sex, that weakens F-8. 14:53.800 --> 14:59.110 Weakness of the last move we have queen takes and fight check 15:01.930 --> 15:08.050 sorry queen sex things check this this is the absolute most incisive Forget using our fight here we 15:08.050 --> 15:12.820 take on sex so basically not too many moves. 15:12.820 --> 15:14.940 There's only kingly seven and that runs into night, I think. 15:14.980 --> 15:15.670 Checkmate. 15:16.930 --> 15:21.130 So yeah, it's a very interesting attacking game. 15:21.130 --> 15:27.010 It looks as though Alexander Alekhine, he's played the Queen's Gambit not in the style of Capablanca 15:27.130 --> 15:28.270 for sure. 15:28.720 --> 15:38.110 He's basically used the pawn as a kind of gambit pawn trying to invest material into damaging the opponent's 15:38.650 --> 15:39.670 king safety. 15:39.670 --> 15:47.740 So letting D4 drop and black, you know, taking this does incur some risks and has to play more precisely 15:47.740 --> 15:48.550 in general. 15:48.580 --> 15:52.600 And the precision required is often too much for human opponents. 15:53.380 --> 16:01.240 So here yeah it's just really, really tricky position here it starts to be but especially with these 16:01.240 --> 16:03.610 nice little moves like before. 16:03.610 --> 16:06.120 So in some reactions, we're going to be winning the Queen Queen if I'm wrong. 16:06.180 --> 16:06.630 C5. 16:06.670 --> 16:12.700 But now there's this Queen is now invading on these dark squares away from the glare of the specialists 16:12.700 --> 16:13.690 on the other side of the road. 16:13.690 --> 16:18.730 So these dot square entry points become the source of disaster here, basically. 16:18.790 --> 16:19.180 Yeah. 16:19.210 --> 16:19.840 Fun stuff. 16:19.840 --> 16:23.260 I hope you enjoyed this one as much as me and so much.
