WEBVTT 00:00.990 --> 00:01.570 Hi there. 00:01.590 --> 00:07.680 In this lecture, Alexander Alekhine is playing against Milan Vidmar in 1911, caused by too much round 00:07.680 --> 00:14.940 one we see E4 from Alekhine e59239669339 ten six. 00:14.940 --> 00:19.530 So the full Knights now here Bishop b five is played. 00:20.160 --> 00:23.370 I quite like G three which is the system. 00:23.370 --> 00:29.940 Grandmaster Gleich later had some really good games with G4 and I've recommended this in my Kings engine 00:29.940 --> 00:36.840 attack course and if we check most databases like Li Chess, they have 35% win rate for white with JI 00:36.970 --> 00:46.830 free and that's over quite a number of games, actually over 1700 games compared to Bishop B5, which 00:46.830 --> 00:48.510 is more trendy. 00:48.510 --> 00:51.420 Sure, over 5500 games. 00:51.420 --> 00:53.040 But the win rate goes down. 00:53.040 --> 00:58.380 I mean, this is just statistical information though, so the win rate goes down to 29%. 00:58.380 --> 01:01.470 So the system, I believe, is a lot of fun, actually. 01:01.470 --> 01:06.570 So, for example, Bishop C5, you might think, well, blacks classically placed, we can play h free 01:06.580 --> 01:09.570 head, stop the pen and play it like a king's engine attack. 01:09.570 --> 01:14.670 So there's a kind of ready made plan of laser perhaps advancing on the kingside. 01:14.670 --> 01:17.640 But anyway, in the game Bishop B5 is played. 01:17.640 --> 01:20.460 We have Bishop before both sides. 01:20.460 --> 01:24.690 Castle Now Bishop takes C six is head B tanks. 01:25.170 --> 01:29.190 So Knight takes E5 black sacks that pawn but is hoping to get it back. 01:29.190 --> 01:36.960 Queenie eight We have knight G4 here Knight D free isn't entirely dull because there's opposite kind 01:36.960 --> 01:42.390 of bishops, which becomes a feature of the game anyway, and black gets the pawn back here. 01:42.690 --> 01:50.250 But this position is actually slightly better for White's overall, but in the game Knight G4 is another 01:50.250 --> 01:51.120 interesting move. 01:51.120 --> 01:56.310 We have Knight takes E4, so there's a very interesting point made by Alekhine in this position. 01:56.310 --> 01:58.440 Can you see what it is for 100 points? 02:02.350 --> 02:02.590 Okay. 02:02.590 --> 02:04.120 Very interesting point made. 02:04.210 --> 02:05.770 Check will check is 1986. 02:05.770 --> 02:06.310 Check. 02:07.000 --> 02:08.680 Now King H.A. is played. 02:08.680 --> 02:15.410 If G takes there is Queen G for check and then Queen takes E for this position. 02:15.430 --> 02:16.870 Let's imagine this position. 02:16.900 --> 02:25.360 It is actually a small edge for wings, but maybe that's the safe route for blank's play. 02:27.490 --> 02:30.960 But Black played King H and we have a very interesting situation. 02:30.970 --> 02:36.620 Rookie 1d5, the three and now Queen E5. 02:36.640 --> 02:41.830 This is a creative move, but maybe not so good as what could have been played. 02:42.190 --> 02:45.520 It's still in a pin that night Night. 02:45.520 --> 02:47.950 Take C free hits. 02:49.020 --> 02:50.160 The queen hair. 02:54.280 --> 02:55.060 And. 02:57.090 --> 02:59.280 The thing is, the bishop's on before, right? 02:59.490 --> 03:00.810 So this is made possible. 03:00.810 --> 03:02.910 So Rook takes it. 03:02.940 --> 03:07.590 Let's say there's 1961 because the bishops won't be for holding a fight. 03:08.730 --> 03:13.920 And if Knight takes seven checking G8, this position just ends up winning for black. 03:14.040 --> 03:19.260 If we go back here and say B B tank, C three Bishop e seven is possible. 03:19.260 --> 03:22.980 Queen A3, Bishop E six point only has a small edge. 03:22.980 --> 03:25.800 So that basically is an option for Black Knight. 03:25.800 --> 03:28.290 Take C three, which wasn't used. 03:30.450 --> 03:33.900 And there's another possibility I just want to mention here. 03:36.630 --> 03:43.380 So here of the 12 B tank C frame, Bishop E seven, Queen F3. 03:43.410 --> 03:44.880 So I mentioned Bishop E six. 03:45.210 --> 03:50.340 If G tanks H six hand, you might wonder what why isn't Black doing this? 03:51.270 --> 03:56.760 The thing is, there's Queen E three in this position, which is really cute. 03:57.900 --> 04:00.930 So the bishop can't move without giving the pace back. 04:00.930 --> 04:04.290 Bishop e Sex doesn't quite work because Queenie five shank. 04:05.430 --> 04:09.160 Now, if King G is played, there's Bishop takes H six. 04:09.210 --> 04:13.770 Even though Wayne's the bishop down, the bishop has got back because black has to play f6, giving 04:13.770 --> 04:16.050 the Bishop back with the advantage for white. 04:16.560 --> 04:23.160 So yes, on Queen E five check f6 if it was played that f6 instead. 04:23.190 --> 04:25.890 This is still going to be okay for white. 04:25.900 --> 04:27.330 It's going to be pleasant for white. 04:27.360 --> 04:28.680 So yeah, funny stuff. 04:28.680 --> 04:31.420 But Knight thank scifri. 04:31.440 --> 04:34.800 Yeah, it does seem like the whites go. 04:36.380 --> 04:37.640 But Queenie five his play. 04:37.640 --> 04:39.060 We get a very interesting position now. 04:39.080 --> 04:42.030 Detox e for default. 04:43.760 --> 04:48.950 If G takes then E tanks D5 hitting the Queen. 04:49.280 --> 04:52.640 And this position is actually a very good tactical move here. 04:52.640 --> 04:54.590 Can you see what that is for? 04:54.590 --> 04:55.430 Five points? 04:58.400 --> 04:58.820 Yeah. 04:58.820 --> 05:02.870 There's bishop saying each sex looking at the rook. 05:03.080 --> 05:08.120 If queen sex there's Queen Dee for Jack and I'm taking out this B4 with advantage for wine. 05:08.240 --> 05:14.300 So anyway D4 was played and we have a very cute move which. 05:17.100 --> 05:19.050 Does create an advantage for white. 05:19.080 --> 05:20.190 Can you see what that is? 05:20.190 --> 05:21.540 Is quite subtle stuff. 05:24.780 --> 05:25.440 Okay. 05:25.530 --> 05:27.570 The cute move is actually a free. 05:29.520 --> 05:30.420 It's trying to unpin. 05:30.450 --> 05:32.280 Here we have details. 05:32.320 --> 05:32.900 See free. 05:32.910 --> 05:37.830 If g takes then eighteenths D tanks. 05:38.340 --> 05:43.290 There's actually in this position we have opposite kind of bishops, which can be really painful for 05:43.290 --> 05:47.580 both sides, but especially for black, because it's more opened up on those dark squares. 05:47.580 --> 05:49.960 There's more access routes to the king. 05:49.980 --> 05:52.240 Guess what White has as a resource here? 05:52.260 --> 05:53.220 Key resource. 05:55.330 --> 05:56.310 If you were white. 05:56.320 --> 06:02.380 So both sides have got extreme imbalances against each other, but we are facilitated with this structural 06:02.380 --> 06:02.860 damage here. 06:02.860 --> 06:07.630 We can play Bishop free with the bishop before if C takes Bishop D form. 06:07.720 --> 06:09.120 Yeah, we're going to be just winning here. 06:09.130 --> 06:11.260 The Queen if. 06:12.080 --> 06:14.650 Bishop a5 is played b4 Bishop B6. 06:14.660 --> 06:20.540 We can grab that bishop with 94 and again blacks humming their own dot squares. 06:20.540 --> 06:24.500 We can play this position and we're looking forward to a nice edge. 06:24.500 --> 06:28.730 So for example here we're looking forward to taking out B6. 06:28.730 --> 06:37.340 And then I move like to see Fred's actually good against the pin and yeah, this is just going to be 06:37.340 --> 06:38.600 favorable for Waynes. 06:38.780 --> 06:41.900 So OC D takes his plate here. 06:41.900 --> 06:42.890 It hangs. 06:44.520 --> 06:47.370 There was an alternative based on tactics. 06:48.160 --> 06:49.510 In this position. 06:51.390 --> 06:56.340 Which is actually nine takes of seven rogue tanks and not queen. 06:56.640 --> 06:58.860 Because there's eight but eight hikes here. 06:58.890 --> 07:07.080 So this pool is immune that this move order could have been used if Queen f6 just rook have one. 07:08.780 --> 07:10.650 As possible protecting F two. 07:10.670 --> 07:12.110 This is a funny situation. 07:12.110 --> 07:14.300 So Queen X was looking at F two about C texts. 07:14.300 --> 07:17.360 We can just take here immunity because of Queen. 07:17.390 --> 07:18.650 There's a penalty, Queenie. 07:18.650 --> 07:23.540 Seven Rook five is better for white, but also even better if black tanks. 07:23.540 --> 07:25.550 Then there's a weakness of the last move. 07:27.020 --> 07:29.750 We could play queen with the classic back row, mate. 07:30.080 --> 07:30.500 So. 07:30.530 --> 07:36.380 Okay, so anyway, eight takes was played this move order C text and we get nine text F seven here. 07:40.050 --> 07:46.170 So in this position, Rook B one was also alternate B types. 07:46.210 --> 07:53.640 97 check can be played in this particular move order with Queen J mating so blank would have to be careful 07:55.320 --> 07:56.820 in this situation. 07:56.820 --> 08:02.700 So anyway, so in this situation with Rook takes up seven. 08:02.700 --> 08:03.690 That's impossible. 08:04.650 --> 08:06.990 Okay, let's go back to the game. 08:06.990 --> 08:15.840 So in the game C takes B to nine times F seven check, King G eight is played and now Rook B one. 08:15.900 --> 08:20.910 So we reach a situation here where there's going to be opposite kind of bishops. 08:21.820 --> 08:24.510 And, you know, usually those are drawn on the King's Cross. 08:24.510 --> 08:27.450 Yes, In the middle game, though, there are extreme imbalances. 08:27.450 --> 08:32.940 If there's a king safety issue that comes out, it's like really good attacking weapon quite often to 08:32.940 --> 08:34.260 have obviously killed the bishops. 08:34.650 --> 08:37.920 And there has been some damage to the king here for black's king. 08:42.060 --> 08:46.570 Well, it could have also by the way, played neat takes E5. 08:46.590 --> 08:51.840 If B takes A1, this position is better for one of the Queen D five. 08:51.870 --> 08:53.790 This is an advantage for White as well. 08:54.090 --> 08:59.880 It's a bit tricky maybe, but overall it's better for one, but b one. 09:00.360 --> 09:02.130 We have rook tanks F seven. 09:03.060 --> 09:04.830 If B tanks C one. 09:04.830 --> 09:08.970 Here Cleaning knight takes E5 Queen tanks one. 09:09.210 --> 09:11.270 This position is better for white as well. 09:11.280 --> 09:16.560 These end game transitions because of chipping out that pawn structural damage over here. 09:16.890 --> 09:19.660 They're likely usually to be better for one. 09:19.680 --> 09:20.610 This is better for white. 09:20.640 --> 09:21.540 This position. 09:22.550 --> 09:26.150 This component is significantly better for wine. 09:26.240 --> 09:31.160 So anyway, Rook takes f7 was blind and now. 09:31.160 --> 09:33.380 Yeah, the bank, you know, bank a bit vulnerable. 09:33.380 --> 09:34.730 Bishop takes B2. 09:35.930 --> 09:37.550 We have Queen G five. 09:40.230 --> 09:43.200 We have Queen Bee free now. 09:43.650 --> 09:46.890 So this gold's actually any Bishop H free stuff as well. 09:47.130 --> 09:50.160 So Queen D, Frank, Bishop E, Bishop Defoe. 09:50.190 --> 09:55.680 Now, this is a fantastic position actually, for the Bishop looking in both directions. 09:56.610 --> 10:04.140 Fantastic position, Rook the Queen e free on pinning and offering the exchange of Queen's blank refuses 10:04.140 --> 10:05.060 Queen B five. 10:05.070 --> 10:07.890 If Queen takes e free, Bishop takes E free. 10:08.310 --> 10:15.150 This scenario in the endgame is actually quite nice for whites, for example, here. 10:15.540 --> 10:17.940 So this is quite nice for one hand. 10:18.720 --> 10:22.790 So Bishop takes a seven, was played on Queen B5. 10:22.800 --> 10:24.750 So Queen B five, Bishop takes 87. 10:24.990 --> 10:26.970 Queen A4 C three. 10:27.000 --> 10:27.790 That's good enough. 10:27.810 --> 10:32.370 Bishop C for Bishop D for white is significantly better here. 10:33.180 --> 10:40.500 The structural damage over here, the fine bishop looking at G seven, we have Rook eight, Queen D 10:40.500 --> 10:41.220 two. 10:41.700 --> 10:43.890 And this is a very good move. 10:44.700 --> 10:45.810 I mean, it's a central move. 10:45.810 --> 10:47.820 It has some flexibility as we're about to see. 10:47.820 --> 10:58.530 h6h3, Queen B five and now tries to get this A4 rook one rook free was also plausible if Queen G five. 11:00.320 --> 11:06.020 Queen C one Queen A4 Rook G frame is going to be good pointing at G seven. 11:06.020 --> 11:08.150 That would be the point of that looking at G seven. 11:08.270 --> 11:11.610 This position is nice for once, but okay. 11:11.630 --> 11:18.290 Rook a1 We have rook for Queen C two rotates A1. 11:18.890 --> 11:21.710 Bishop So Rook takes A1 and now Bishop D3. 11:21.740 --> 11:23.650 This has a weakness of the last move. 11:23.660 --> 11:32.120 It's weakened A2 And in fact, first there's Rook eight check now King H seven. 11:33.590 --> 11:38.300 If Rook have eight, Queen A2, check Quincy for rook tanks F eight. 11:38.300 --> 11:41.470 This position with King tanks f8 Queen eight. 11:41.570 --> 11:43.550 Check King f7. 11:43.670 --> 11:47.000 There's actually a fine resource here showing the power of this. 11:47.000 --> 11:49.490 Bishop White's so dangerous. 11:49.820 --> 11:54.980 The opposite of bishops, especially when there's a king safety issue, we can play for ten points. 11:54.980 --> 11:55.790 What would you play? 11:58.370 --> 11:58.750 Yeah. 11:58.760 --> 12:00.160 Queen H eight. 12:02.000 --> 12:04.610 Blank spaces would have difficulty defending here. 12:04.730 --> 12:07.100 This is just a very big advantage for for white. 12:07.310 --> 12:10.820 So anyway, King seven is played here. 12:14.080 --> 12:15.770 And we have now Queen A2. 12:15.790 --> 12:17.050 That's a nifty move. 12:18.550 --> 12:21.340 Queen H five Protecting the rook like that. 12:23.910 --> 12:24.480 Queen. 12:24.510 --> 12:26.770 E-6 And this is so dangerous for blacks. 12:26.790 --> 12:28.410 KING Now, we have. 12:28.410 --> 12:29.460 ROOK Sorry, we have. 12:29.460 --> 12:30.360 BISHOP Have fun. 12:30.370 --> 12:33.120 This is a very cheeky move, trampy move. 12:33.240 --> 12:34.140 It's bypassed. 12:34.140 --> 12:35.710 I mean, it's just ignored with Rook. 12:35.730 --> 12:38.830 A5 If King takes, then that would be a blunder. 12:38.850 --> 12:44.010 Queen D one check blunder and half So Rook five is played. 12:44.490 --> 12:46.560 Queen D one, King H two. 12:48.480 --> 12:50.610 And this is just terrible for black. 12:50.610 --> 12:51.120 The King. 12:51.120 --> 12:52.530 The King has had it here. 12:52.530 --> 12:53.330 Actually. 12:53.340 --> 12:54.960 This is a desperate move. 12:55.800 --> 12:56.720 Bishop Thanks, G2. 12:56.730 --> 13:01.280 The thing is, if Rook have a how would you win this? 13:01.290 --> 13:02.760 Can you see a way of winning this? 13:05.160 --> 13:05.460 Yeah. 13:05.490 --> 13:07.500 Queen E seven wrote in here. 13:07.530 --> 13:08.430 What would you play? 13:10.720 --> 13:14.500 I mean, we're basically playing with an extra piece here with that Bishop gunning G7. 13:14.500 --> 13:16.300 But how do we actually make use of it? 13:17.050 --> 13:19.480 There's a phenomenal move here. 13:19.480 --> 13:21.460 Very instructive in my view. 13:22.550 --> 13:25.500 Yeah, we can play Queen F seven, it looks like. 13:25.530 --> 13:26.720 Well, what's the point of that? 13:26.740 --> 13:30.900 The point is Queen F seven to nudge the king away from G six. 13:30.910 --> 13:34.240 If we can get into G six, it's going to be game over. 13:34.240 --> 13:34.550 Sorry. 13:34.570 --> 13:37.180 Bishop B five, Queen F five, check. 13:37.750 --> 13:39.190 And this is decisive. 13:39.640 --> 13:43.090 If G six were mating of Queen of seven shank. 13:43.660 --> 13:49.290 And the other point is, if instead King H eight. 13:49.300 --> 13:59.410 Yes, we get into G six with a killer threat of queen thanks h six check and also because all rooks 13:59.410 --> 14:03.550 on a five, you know, it's pretty hopeless, actually. 14:04.480 --> 14:08.680 So Queen E two, queen size H six is main. 14:08.980 --> 14:12.190 Queen C one we complain. 14:12.640 --> 14:13.390 Bishop Thanks. 14:13.390 --> 14:16.450 G seven Chang Rogue Rook eight. 14:16.990 --> 14:20.440 And then that's going to be mating with Queen. 14:20.440 --> 14:22.830 So you can see how dangerous it is. 14:22.840 --> 14:24.910 And it's opposite of Bishop's Knights. 14:24.910 --> 14:29.710 So this, this move is just a losing move, I mean, in a lost position. 14:29.830 --> 14:34.200 King takes his blade, Queen F Jack and the Bishop because it's on D4. 14:34.240 --> 14:34.690 It's. 14:34.690 --> 14:36.160 Yeah, it's handling F two. 14:36.340 --> 14:38.620 Rook F we have Rook Ain't black. 14:38.620 --> 14:39.580 Could have just resigned. 14:39.580 --> 14:42.490 Rook have seven Queen G for Queen D three. 14:42.490 --> 14:46.720 And now Black resigns after Rook eight trying to drag the rook away from G seven. 14:46.900 --> 14:51.580 If Rook D seven Queen f5g68 is checkmate. 14:52.900 --> 14:58.060 So yes, I thought this was an interesting game example with the opposite kind of bishops out of the 14:58.060 --> 15:05.830 opening and slight damage around Black's king, which amplifies even more that extreme imbalance that 15:05.830 --> 15:12.250 White has that bishop without the counterpart in this part of the game. 15:12.250 --> 15:19.660 So 9 seconds have seven cute stuff doing a bit of damage there and yeah, it's surprisingly tricky for 15:19.660 --> 15:20.230 Black. 15:20.230 --> 15:26.590 So White's plan of getting a central bishop and getting attacking opportunities later, it was just 15:26.590 --> 15:31.390 absolutely quite convincing, especially because the Queen stayed on the board. 15:31.390 --> 15:34.390 That favors the attacker quite often. 15:34.390 --> 15:39.880 So yeah, it's a rich position, but quite tricky for black to actually hold this position. 15:39.880 --> 15:41.500 So fascinating stuff. 15:41.830 --> 15:43.960 And the queen started seizing control of things. 15:43.960 --> 15:52.180 And once, you know, he had control of the A4, this position starts to get really, really tricky. 15:52.300 --> 16:01.480 This is just, you know, Black's kind of in a paralyzed state here, actually. 16:01.480 --> 16:07.240 And also, by the way, there are little tricks hand going on if Queen G6 because the Rooks on eight, 16:07.270 --> 16:08.770 what would you play here? 16:10.400 --> 16:12.210 His little trick ain't. 16:12.290 --> 16:15.440 So it shows the difficulty of Black's position. 16:17.120 --> 16:19.460 What does Black actually do here? 16:20.940 --> 16:24.450 Yeah, it's it's just very, very tricky in this position. 16:26.250 --> 16:29.810 So, yeah, if the rook moves off, there's. 16:30.620 --> 16:34.910 There's a bigger type of queen she ain't check if the move somewhere. 16:34.920 --> 16:35.130 Yeah. 16:35.130 --> 16:38.040 So this is, you know Rook five. 16:41.880 --> 16:47.250 Is bypassing blacks trap and just an absolutely winning position here off the cutting edge to. 16:48.900 --> 16:49.650 As we say. 16:49.650 --> 16:51.150 So yeah, it's so powerful. 16:51.150 --> 16:57.750 The bishops basically both sides have bishops of our counterpart, which is representing an extreme 16:57.750 --> 17:04.710 imbalance, representing a big advantage in that particular domain of the dark squares here, because 17:04.710 --> 17:08.310 black has already suffered missing a key pawn around the king. 17:08.310 --> 17:10.050 Black's king is weaker than usual. 17:10.170 --> 17:14.760 And these tactics, these combinations are quite interesting. 17:14.760 --> 17:15.740 What results? 17:15.750 --> 17:18.600 OC Have you enjoyed that say much?
