WEBVTT 00:00.900 --> 00:01.770 Hi there. 00:01.800 --> 00:08.070 In this lecture, we see Akiva Rubinstein playing against Alexander Alekhine In the 1926 Dresden two 00:08.400 --> 00:09.420 around six. 00:09.960 --> 00:15.340 We see D4 Knight have six knights F3 e6 Bishop F4. 00:15.360 --> 00:17.010 So a London system actually. 00:17.430 --> 00:21.960 So the modern move order for the London system that I've recommended, if you check my London system 00:21.960 --> 00:25.380 of course is actually to play Bishop F4 immediately. 00:25.380 --> 00:27.570 Sometimes by not having a free. 00:27.720 --> 00:34.440 There are subtle advantages like the D1 2h5 diagonal and bat preparation in lions where Queen B six 00:34.440 --> 00:35.370 is played by. 00:35.370 --> 00:37.200 Here we have a traditional London system. 00:37.200 --> 00:37.950 Move order. 00:38.250 --> 00:40.110 So what does Alekhine play here? 00:40.410 --> 00:41.880 He plays actually B6. 00:41.880 --> 00:49.080 It seems a logical move trying to control E4 more so H Frank Bishop B seven, Knight BD two and he sorts 00:49.080 --> 00:53.340 out this annoying bishop with Bishop D things not minding of the pawns get doubled. 00:53.340 --> 01:00.450 So a dynamic treatment we have, you know, an alternative you could consider a D5, but it does block 01:00.450 --> 01:01.380 in the Bishop. 01:01.380 --> 01:08.250 However with Bishop d6 here it has kind of used the move h three and if the bishops are swapped off 01:08.250 --> 01:10.230 here, it looks to be about equal. 01:10.230 --> 01:17.340 And funnily enough, this kind of method for Bishop D6 has been favoured by Magnus Carlsen in many games 01:17.580 --> 01:19.080 at various time controls. 01:19.230 --> 01:20.580 So interesting stuff. 01:20.580 --> 01:25.860 So we see Bishop D6 though and White accepts the offer to double the pawns. 01:26.070 --> 01:30.480 So C takes d6 e free black castles. 01:30.510 --> 01:35.880 Bishop Ito So an advantage here for one moment is the Bishop saying that, but it's actually closed 01:35.880 --> 01:43.380 voluntarily to keep a grip on key squares white castles 96 we see C free. 01:44.760 --> 01:46.680 You might wonder what about C4? 01:47.010 --> 01:49.380 Adventurous D take C4, Bishop, take C4. 01:49.410 --> 01:51.840 This should be fine for black. 01:51.840 --> 01:56.430 If we imagine this scenario, let's take it a bit further with D6. 01:56.430 --> 01:58.020 This should be fine here. 01:59.200 --> 02:03.040 Bishop takes a six, queen takes a six if black plays like this. 02:03.100 --> 02:05.340 This looks like a fine enough position. 02:05.350 --> 02:07.030 And there's even some traps. 02:07.210 --> 02:11.920 If Rook see two knight before, so you know why has to tread carefully. 02:12.130 --> 02:17.680 If the queen retracts after that exchange of the bishops, there should be about equal. 02:18.190 --> 02:20.290 Okay, but see, free was played. 02:20.650 --> 02:27.920 We have Knight E4, so not minding the double pawns being exchanged for doubled pawns with double E 02:27.970 --> 02:28.600 pawns. 02:28.630 --> 02:33.370 Why accepts that offer details 92 now A5. 02:33.970 --> 02:37.300 Now here White plays A4. 02:37.330 --> 02:40.090 This seems a little bit controversial. 02:40.420 --> 02:45.940 There is a kind of cost associated with this, you know, cost of downsides associated with this in 02:45.970 --> 02:49.420 that black could play G5 and E3 is weak. 02:50.110 --> 02:51.970 Potentially, it's like a backward pool. 02:51.970 --> 02:56.740 Now, there's no pawns kind of supporting that pawn on F3. 02:56.740 --> 03:02.230 So any entrance to rook G4 in a later if that uses the G4, that's going to be a target. 03:03.070 --> 03:05.560 So this is controversial this move. 03:05.590 --> 03:11.050 If Rook C1 instead the E5 Queen E1 one rook this should be about even. 03:11.350 --> 03:16.270 But with F4 there is a target and G5 is played a very aggressive move. 03:16.420 --> 03:20.680 So alekhine thinking about attacking potential attacking combinations the G4. 03:21.250 --> 03:23.390 It's the sort of thing I absolutely love. 03:23.410 --> 03:24.850 Just French Open the G5. 03:24.850 --> 03:26.080 I'll use that. 03:26.080 --> 03:28.270 Excuse the F for pawn as a lever. 03:30.100 --> 03:31.900 So it's a lever pawn to wrench open the file. 03:32.200 --> 03:33.460 C4 is played. 03:33.580 --> 03:41.200 If G3 white could play G3 about 97 this position black should have a small edge just maintaining the 03:41.200 --> 03:42.190 tension here. 03:42.760 --> 03:45.790 But anyway, the C4 is played and we have d5. 03:47.230 --> 03:48.280 D5 is interesting. 03:48.280 --> 03:50.020 97 was also possible. 03:50.020 --> 03:53.770 So for example, if 9595 when we're looking at E3. 03:54.010 --> 04:02.950 So this situation D6 and here plant gets a strong position for example with G tanks he takes it and 04:02.950 --> 04:05.490 just let B5 go. 04:05.620 --> 04:10.600 There's enough power in the position while the knight's on D5 and there's no C4 immediately without 04:10.600 --> 04:13.720 B takes if one accepts a pawn sack here. 04:13.870 --> 04:15.910 This is quite vicious position. 04:16.360 --> 04:20.380 For example, Bishop C4 E3 and look, look at this. 04:20.950 --> 04:22.990 Now the bishops probing G2. 04:23.320 --> 04:25.530 This would be a remarkably strong attack. 04:25.540 --> 04:28.780 Knight takes a fall, and this is possible. 04:28.780 --> 04:35.020 Even though White's got some material, there's Queen G5 winning a whole rook in broad daylight with 04:35.020 --> 04:39.100 E5 end of game, basically the going to be lost. 04:40.330 --> 04:49.510 So yes, there are amazing attack potentials with 97 and this idea of Knight D5, but we have D5 instead 04:49.750 --> 04:52.570 99, 95, 99 c5d tanks. 04:52.570 --> 04:58.330 Cage ain't a full rook, G ain't Queen d2g takes her four. 04:58.840 --> 05:02.020 And now, yeah, this looks fragmentation. 05:02.020 --> 05:05.920 All these pawns are now isolated and kind of doubled. 05:05.920 --> 05:08.020 And that's potentially going to be picked off later. 05:08.380 --> 05:09.670 That's going to be probed later. 05:09.670 --> 05:11.290 They're both liabilities. 05:12.160 --> 05:16.830 If he takes his plate though, this G4 is gorgeous. 05:16.840 --> 05:21.640 Queen H four threatens lots of things like Queen size H three. 05:21.640 --> 05:30.310 But let's say Rook have F2 because well, if King H two Queen G4 in white gets mated. 05:30.310 --> 05:32.830 So let's say rook f2 rook g3. 05:32.830 --> 05:34.870 Forget Queen takes H3 for a moment. 05:35.140 --> 05:38.320 We've actually got support for E4 either. 05:39.070 --> 05:43.960 So Queenie one against F3, no C4, E3 for King, Queen and Rook. 05:43.960 --> 05:47.740 So Queen E one, but then the rook stable and then this is devastating. 05:47.740 --> 05:53.290 Rook take sanctuary end of game basically Black's crushing it there so. 05:53.830 --> 06:03.580 Okay but so rook takes F4 was played You can understand why Black doesn't want to wake up Black's bishop 06:03.580 --> 06:15.010 especially so King Safety first Queen G5 Bishop one Queen G3 King H one Queen G seven Looking at E5. 06:15.010 --> 06:22.480 So this is a great way of pointing at E5 and we have Queen D4 and now funnily enough, Bishop A6 so 06:22.480 --> 06:24.880 the Bishop can't move away from G2. 06:25.240 --> 06:26.710 We have Rook F2. 06:29.290 --> 06:29.590 Yes. 06:29.590 --> 06:33.970 If the rook if the bishop moves away, we just use that weakness of the last move. 06:34.090 --> 06:42.940 Okay, so Rook f2, we have Queen G3, Rosita and now Bishop takes F1 and this actually subtly weakens 06:42.940 --> 06:45.460 the C4 square in particular. 06:46.000 --> 06:53.350 So we have Rook ac a and there is actually a kind of threat of rook C4 here to hit the queen and the 06:53.350 --> 07:00.040 A4 pawn and that's parried would be free rook D2 would be a very amusing for rook C4 trapping the queen 07:00.880 --> 07:09.550 but anyway B3 controlling C4 and we have now rookie seven. 07:11.620 --> 07:16.900 This is an interesting decision to kind of use that tempo gainer to switch the G4, but there was also 07:16.900 --> 07:28.120 actually Queen H4, which is surprisingly effective because queenly to rook, Geoffrey Rook and for 07:28.120 --> 07:28.810 Queen G5. 07:28.810 --> 07:34.570 This situation with Rook coming to G8 is an interesting arrangement. 07:34.830 --> 07:36.070 Threatening. 07:36.070 --> 07:46.510 For example, Rook takes h free check if queen have two queen E seven and it's difficult for white to 07:46.510 --> 07:51.820 hold on him because of this threat of Queen C5 looking at G three. 07:52.270 --> 07:55.870 So Queen G1, Queen C five and then taking out E free. 07:55.870 --> 08:01.570 It's going to be an enormous possession of black and instead of queen, you want to be fourth stop Queen 08:01.570 --> 08:05.500 C5 back to G seven and look at E5. 08:05.500 --> 08:07.030 You know, E5 is going to drop. 08:07.030 --> 08:10.840 So these pawn liabilities can be probed in various variations. 08:10.960 --> 08:17.500 So yes, Queen H four is very interesting, but Rook C7 was played Rook E two and now the rook switches 08:17.770 --> 08:23.230 rook a4 rook g6 Queen b4 and now Rook h6. 08:23.230 --> 08:25.420 So Francis Rook takes h six. 08:26.830 --> 08:31.780 I wrote six takes eight free rather, and then G takes Queen G One is checkmate. 08:31.780 --> 08:33.420 So H four is played. 08:33.430 --> 08:37.840 This doesn't look great just to put that on the board, just to show you clearly. 08:37.840 --> 08:40.210 Queen Rook takes H three check. 08:40.720 --> 08:42.760 You can see this is not good news. 08:42.910 --> 08:44.980 G takes Queen G one is checkmate. 08:46.380 --> 08:54.660 And if King g1 Queen H to check rogue takes g to chase all crashing through for a checkmate sequence. 08:54.930 --> 09:04.790 So ock h four is tried and we have Queen G seven So looking at e5 C4, but now instead of E5, yeah, 09:04.830 --> 09:09.990 going for the King of G6, Queen D two and I'm Rook g free. 09:10.920 --> 09:12.840 Okay, so this is getting quite vicious. 09:13.170 --> 09:18.450 Queen E one and now Rook takes E three ends the game White resigns here. 09:19.500 --> 09:21.120 So this is very strong. 09:21.690 --> 09:24.370 There was also even a stronger move. 09:24.390 --> 09:26.460 It turns out Rook takes G2. 09:26.490 --> 09:27.150 Yes. 09:28.260 --> 09:30.650 And what does y actually do? 09:30.660 --> 09:31.860 You know, be free. 09:33.030 --> 09:37.160 We're going to play Rook G one check if if Rook have one. 09:37.170 --> 09:40.580 The thing is, Queen G4 looks at Queen H three. 09:40.590 --> 09:41.940 This is just devastating. 09:41.940 --> 09:44.070 So that was another way of playing it here. 09:44.100 --> 09:45.150 It just takes G2. 09:45.150 --> 09:48.420 But Rook takes E3 is winning as well. 09:48.420 --> 09:57.360 So say C takes Rook, takes E to Queen, takes E to Queen, takes E5, hits this rook black is metro 09:57.360 --> 10:03.840 up with a dominating mass of pawns here and this is quite interesting as well, but even more brutal. 10:03.840 --> 10:06.350 Yeah would have been rook takes you to in the end. 10:06.360 --> 10:09.000 So anyway, this is the game in possession. 10:09.000 --> 10:15.420 So I thought this game was interesting that when there's an opportunity to open up a GFL road to the 10:15.420 --> 10:20.610 King, this is about G4 roads that we should really take this kind of seriously. 10:20.610 --> 10:26.790 This situation where we're presented with a move which maybe ordinarily you think you shouldn't move 10:26.820 --> 10:29.520 pawns around your king, but it's all about exploits ability. 10:29.550 --> 10:31.230 Can you actually get away of it in this position? 10:31.230 --> 10:36.690 Because White's pieces are quite passive here and we can get away with this G5. 10:36.690 --> 10:37.680 We're not going to get mated. 10:37.680 --> 10:43.380 You know, maybe there's certain situations it would lead to us getting mated to move on g pawn, but 10:43.380 --> 10:48.390 sometimes we can use the pawns aggressively to create very aggressive roads to the opponent's king. 10:48.390 --> 10:49.740 So that was the case here. 10:49.760 --> 10:52.680 Very dangerous final, this semi-open farm. 10:52.680 --> 10:54.150 It's like one way traffic. 10:54.150 --> 10:56.880 I love semi fouls for the attacking player. 10:56.880 --> 10:58.590 It's like a one way road. 10:58.590 --> 10:59.610 You're sending your cars. 10:59.610 --> 11:01.980 The opponent and the opponent can't send the cars back. 11:01.980 --> 11:03.960 So a beautiful semi-open file. 11:03.990 --> 11:09.150 This is a lovely position for attacking potential OC. 11:09.210 --> 11:12.750 So I hope you enjoyed this game as much as me and so much.
