WEBVTT 00:01.290 --> 00:01.950 Hi there. 00:02.010 --> 00:10.530 In this lecture, we see a theme bogoljubov against Alexander Alekhine in 1922 Hastings Tournament around 00:10.530 --> 00:11.160 ten. 00:11.520 --> 00:12.520 So let's have a look. 00:12.540 --> 00:18.630 D4 from Bogoljubov and we see Alekhine playing the Dutch defense. 00:18.630 --> 00:28.410 We have C4 nine times six and now Finn Cato is signalled G3 E6 and the bishop is Cato Bishop. 00:28.440 --> 00:29.490 B4 check. 00:29.520 --> 00:36.870 Alekhine likes slightly weakening the dart squares and here after Bishop d2. 00:37.170 --> 00:37.620 Yeah. 00:37.650 --> 00:37.950 Bishop. 00:37.950 --> 00:40.380 Thanks d2 Czech 1982. 00:40.410 --> 00:43.770 Of course, Black has also weakened their dart squares. 00:44.100 --> 00:45.160 It's a bit double edged. 00:45.180 --> 00:57.510 96 Knight Geoffrey here if D5 Black could play 97 this position D Tanks D tanks nine GM free 96 should 00:57.510 --> 00:58.770 be about even. 00:58.950 --> 01:00.660 There's no big problem here. 01:01.770 --> 01:03.300 Okay, so. 01:04.840 --> 01:07.780 Of the night and three instead of the five. 01:07.780 --> 01:19.030 We have both sides castling d6 Queen B3, King H eight, Queen C free and now a clever tactical move. 01:19.030 --> 01:21.040 A liberating move is played here. 01:21.850 --> 01:23.140 Can you guess what that is? 01:23.800 --> 01:31.030 If I give you 5 seconds pause video and it does kind of highlight amplify that you know, the dart squares 01:31.030 --> 01:39.190 like D2, you know, it's a bit weaker than usual without having the bishop on C one. 01:39.370 --> 01:41.710 So this move is interesting. 01:41.710 --> 01:49.930 It's E5, so E3 is played here because if D takes D tanks, White can't play, Knight takes E5 because 01:49.930 --> 01:53.320 Knight takes E5 and lo and behold D two drops. 01:53.320 --> 01:57.370 So there's a subtle impact on the dark squares shown there in that variation. 01:57.580 --> 02:05.110 So E3 we have a five and now B3 and they'll queeny eights with the f pawn on F5. 02:05.110 --> 02:13.480 One perk is the Queen can provoke weaknesses, it can support Bishop H3 and maybe can support G5. 02:13.540 --> 02:16.720 It's a dangerous looking queen, a free Queen h5. 02:17.200 --> 02:19.870 We have H four now here. 02:20.950 --> 02:22.510 Alekhine played Knight G4. 02:22.510 --> 02:28.450 It seems that there might be some mileage actually with modern engines checking. 02:28.450 --> 02:35.170 This might be some managing A4 actually, if nothing E1, let's just take this as an example. 02:35.170 --> 02:42.740 Black could build up a straightforward attack here, even if A4 by the use of G5 here. 02:42.850 --> 02:50.380 This is building up a straightforward and kind of dangerous attack which is leaving black with a potentially 02:50.380 --> 02:51.910 large advantage. 02:51.910 --> 03:00.670 This kind of situation Black's in a glorious place now on Knight G5 H six Knight H free, you might 03:00.670 --> 03:00.880 think. 03:00.880 --> 03:06.040 Well, hold on King's Cross and I have for the key move here would be Queenie eight not Queen f7 because 03:06.040 --> 03:13.780 that means F3 and and the rook would be X-raying This is actually the rook would be X-raying The Queen 03:13.780 --> 03:15.940 batter is actually Queen eight in inspiration. 03:16.180 --> 03:24.520 And here in fact G5 again is useful D5 and then this position is going to be an advantage for Black 03:24.520 --> 03:26.320 in a different form. 03:27.070 --> 03:32.640 Plants got a lot of light square pressure and White's pieces are kind of locked in black overall was 03:32.680 --> 03:40.240 is better they're slightly but anyway E4 was an opportunity but knight G4 was used we have nine G5 Bishop 03:40.240 --> 03:48.340 D7 F3 knights have sex and now for white volunteers light squared weaknesses and that kind of locked 03:48.340 --> 03:55.000 in position anyway now so black is significantly better positioning on the light squares in particular. 03:56.500 --> 03:58.650 You know, this pool is poking into light and squares. 03:58.660 --> 04:00.490 This bishop is kind of blunted. 04:02.440 --> 04:04.720 We have rook hefty one, I think. 04:04.810 --> 04:08.940 Knight Frank, D5. 04:09.370 --> 04:09.810 Yeah. 04:09.820 --> 04:12.100 Black doesn't have to go for a G5 plan here. 04:12.130 --> 04:21.730 White is kind of well equipped for that, but D5 we have f19, E seven we have A4, which weakens B4 04:21.730 --> 04:21.970 now. 04:21.970 --> 04:29.410 So not only as white we can g4 now B4 is weaker and 96 would be two knight before the knight occupies 04:29.410 --> 04:30.250 a nice square. 04:31.210 --> 04:33.370 Bishop H1 and now Queenie eight. 04:34.090 --> 04:35.380 So it seems as though. 04:35.380 --> 04:36.220 Hold on a sec. 04:36.370 --> 04:37.720 What's going on here? 04:37.750 --> 04:40.210 Is there a square attack on this side of the board? 04:40.960 --> 04:42.100 Kind of, yes. 04:42.820 --> 04:43.870 We have Bishop. 04:43.880 --> 04:45.460 Sorry, we have rook G2. 04:46.750 --> 04:47.690 And now guess what? 04:47.710 --> 04:48.610 Alekhine place. 04:48.610 --> 04:54.700 So this queen is a very flexible at first, you know, it's like tangling up White's pieces, her congestion, 04:54.700 --> 04:56.080 and they look rather silly. 04:56.080 --> 04:58.420 I mean, this is a defensive posture. 04:58.420 --> 05:04.390 It's like, okay, but on this side of the board D take C4 now is played wonderfully. 05:04.600 --> 05:07.300 Switching attention B take C4. 05:07.330 --> 05:11.140 If Queen takes C4, there's an energetic B5 available. 05:11.830 --> 05:17.860 For example, this position, Queen c1951 is in a very passive way. 05:17.860 --> 05:26.920 Bishop takes F1 and it's kind of getting very difficult here. 05:29.640 --> 05:30.300 For whites. 05:30.300 --> 05:35.740 Indeed, this kind of scenario is very, very nasty. 05:35.760 --> 05:42.750 If King takes F1 the resources like Queen B five check and this is this is becoming unpalatable, this 05:42.750 --> 05:46.230 kind of thing hitting Ephraim before it's so unpalatable. 05:46.230 --> 05:48.780 So it's there's a lot of dangers there. 05:48.780 --> 05:53.850 And if Rook have 293 forks Queen and Rook. 05:55.380 --> 06:01.320 So okay, we have B take C for just letting the A4 pawn go instead. 06:02.010 --> 06:04.020 Yes, it's unfortunate. 06:04.050 --> 06:09.690 We have F2 Bishop 80 79d So now the attack on the light squares continues. 06:09.690 --> 06:15.330 B five 9193 And it looks as though. 06:15.330 --> 06:16.830 Hold on, come on, get the poor man. 06:16.830 --> 06:18.210 Rook takes a five. 06:18.240 --> 06:27.360 We have a fantastic concept now coming up it starts with b4 Rook takes eight and guess what the fantastic 06:27.360 --> 06:29.940 concept is here in this position. 06:29.940 --> 06:32.310 What would you play in this position? 06:37.140 --> 06:37.620 Okay. 06:37.650 --> 06:41.370 We've white spaces kind of huddled up, beating sea free. 06:42.590 --> 06:43.200 Yeah. 06:44.220 --> 06:51.420 Beats even not just taking the rook on eight beating BTC free rook takes eight. 06:51.420 --> 06:55.740 And the point is the magnificent point is actually C two. 06:55.830 --> 06:58.590 And how does white stop the queen? 06:58.740 --> 07:02.490 White takes off on F eight, King H seven. 07:02.490 --> 07:04.140 And we have a marvellous imbalance. 07:04.140 --> 07:12.720 Now see one queen in check nine to have one knights e, one rook, two queen. 07:12.720 --> 07:13.920 Thank C for. 07:15.060 --> 07:16.890 Wrote the eighth and now Bishop be five. 07:16.890 --> 07:20.460 Britain's Queen tanks F1 mating. 07:21.840 --> 07:28.530 So we have rook Saxby five necessary Queen B five and why it's kind of paralysed here we have G for 07:28.530 --> 07:33.090 once trying to get some something going like a free check. 07:33.450 --> 07:42.780 Bishop Tanks, E tanks, G tanks, F five and L Queenie two once in a kind of zugzwang here the five 07:43.050 --> 07:47.490 are now just waiting, saying, Well, why don't you play now after King James? 07:48.150 --> 07:52.650 This is highly problematic, this position, to say the least. 07:53.100 --> 07:56.310 We have h57 again waiting. 07:57.810 --> 07:59.160 And now e4. 07:59.190 --> 08:01.680 This is, this is very, very painful. 08:03.720 --> 08:13.560 If a move like if the rook moves, then there are very painful options like knights e4 and what's happening 08:13.560 --> 08:22.340 there if ever takes there's Queen G2 so it's kind of stuck here and tries e4 Knight takes e4 nine take 08:22.380 --> 08:31.440 for Queen say C4 six that's taken F6 that's taken Rook Ditto. 08:31.440 --> 08:34.590 Now another great move is played. 08:34.590 --> 08:38.370 What would you play here which greatly simplifies the position. 08:38.370 --> 08:43.620 I mean, Black's doing fantastically well here anyway, but this move is marvellous. 08:44.070 --> 08:45.330 Okay, for ten points. 08:48.400 --> 08:49.750 Queen E two. 08:50.530 --> 08:51.210 Yeah. 08:51.220 --> 08:53.380 So this actually simplifies that. 08:53.710 --> 08:57.450 KING After is needed, he takes this this ending. 08:57.460 --> 08:59.380 KING Upon ending is just one. 08:59.740 --> 09:00.760 King G seven. 09:00.760 --> 09:01.400 King E two. 09:01.420 --> 09:02.410 King F seven. 09:02.740 --> 09:03.670 King E three. 09:05.320 --> 09:06.340 King E six. 09:07.000 --> 09:08.350 King, You know, D five. 09:08.350 --> 09:08.860 Check. 09:09.430 --> 09:12.100 And that's the end of the game here. 09:12.100 --> 09:15.410 It's just easily one if. 09:15.430 --> 09:16.510 KING The four. 09:16.510 --> 09:17.200 King of five. 09:17.200 --> 09:18.700 This is just an easy one. 09:18.820 --> 09:20.100 KING Important thing. 09:20.980 --> 09:33.100 So, yes, it really is a very interesting attacking game where we saw in the opening the exchange of 09:33.100 --> 09:41.050 the dark where bishops, which actually kind of helps this F5 liberation, and we get this kind of aggressive 09:41.050 --> 09:50.560 situation now where E4 was possible here, it does seem, but it came up anyway, white just compromising 09:50.560 --> 09:53.770 the light square control here. 09:54.160 --> 09:59.410 So I think it's kind of been tested with his occupation here of the center. 09:59.830 --> 10:02.740 And it's a marvelous switch the other side of the board here. 10:02.740 --> 10:04.810 But first, using the B for weakness. 10:04.840 --> 10:07.030 So there's an accumulation of advantages. 10:07.030 --> 10:12.130 Basically, the true monsters of attack, they accumulate advantages quite often. 10:13.000 --> 10:17.770 And the attack, you know, it doesn't have to result in a checkmate. 10:17.770 --> 10:24.190 It can just result in positional advantages, you know, magnifying, amplifying positional advantages. 10:24.460 --> 10:28.390 But this B5 is a real thing of beauty here. 10:28.390 --> 10:29.290 What happens here?
