WEBVTT 00:01.140 --> 00:02.010 Hi there. 00:02.010 --> 00:08.760 In this lecture, we look at an interesting example, a classic example of Bogoljubov or against Alexander 00:08.760 --> 00:15.120 Alekhine in 1922, the Hastings Mountain we see in this game play on both sides of the board to kind 00:15.120 --> 00:17.520 of overwhelm the opponent positionally. 00:17.850 --> 00:20.040 We see Bogdan JaVale playing D4. 00:20.040 --> 00:30.060 We have f five for Dutch defense from Alexander Alekhine see 4956g3 and now E six Bishop G to Bishop 00:30.060 --> 00:40.080 B for Jack, Bishop D two So square bishops get exchanged off here 90 69gf3 both sides castle and now 00:40.080 --> 00:44.910 D six Queen be free and now King H eight Queen C free. 00:45.180 --> 00:50.520 And this is already a slight inaccuracy allows black to play a very interesting move here. 00:50.520 --> 00:54.330 Can you see what that is which is tactically working. 00:55.470 --> 01:02.760 So White was trying to prevent e five but it's not a very effective prevention move on this occasion 01:02.940 --> 01:05.070 because black just plays now. 01:06.010 --> 01:07.480 Yeah, for ten points at least. 01:07.600 --> 01:08.680 E five. 01:09.850 --> 01:10.840 This is possible. 01:10.840 --> 01:12.010 We have E three. 01:12.010 --> 01:15.370 If D takes E five, D takes nine takes. 01:15.370 --> 01:19.420 The thing is black pathetically just wins a piece at the end of it. 01:19.930 --> 01:21.010 So it's not possible. 01:21.010 --> 01:23.560 So e three and this is not a good sign. 01:23.980 --> 01:29.050 We have now a5b free Queenie eight. 01:29.080 --> 01:33.580 So the Queen looks to be committing just to a kingside attack. 01:33.580 --> 01:35.980 At the moment we see a free queen. 01:35.980 --> 01:43.990 h5b Sorry, H four and now Knight G for already a position will gain that G four square is very cozy 01:43.990 --> 01:44.860 for black. 01:46.330 --> 01:49.900 We have 9g5 now Bishop dd 7f3. 01:49.900 --> 01:53.080 So weaknesses are being provoked as well. 01:54.760 --> 01:58.720 White perhaps should have not played on this side of the board. 01:58.720 --> 02:04.600 And for example, if B for a six this position takes eight takes. 02:04.750 --> 02:07.870 Why actually retains technically a small edge. 02:08.170 --> 02:11.290 So every is creating weaknesses. 02:11.290 --> 02:16.660 We have knight F six, F four and now the bishop shut in after E four. 02:17.440 --> 02:22.450 But on the other hand, White has closed this section of the board. 02:22.450 --> 02:25.660 It doesn't seem as though there's an easy pawn break for black. 02:25.660 --> 02:27.340 We have 86923. 02:27.340 --> 02:30.550 So at least white is holding up against pawn banks. 02:31.090 --> 02:38.140 We have D five now being played 9f1 knights e seven and now a four. 02:38.170 --> 02:43.660 This actually creates another kind of mirror weakness on this side of the board B four. 02:43.660 --> 02:45.760 So both B and G for a weakened. 02:45.760 --> 02:49.570 And the knight actually goes back here to celebrate B four. 02:49.690 --> 02:54.010 So rook d to Knight before we have Bishop H one. 02:54.010 --> 03:01.360 So Y is looking as though white can defend on this side of the board the kingside. 03:01.510 --> 03:07.030 And so here is where the concept of overwhelming the opponent by playing on both sides of the board 03:07.060 --> 03:08.530 is very interesting. 03:08.530 --> 03:14.650 The Queen actually switches back, pivots back and is looking at a four. 03:15.760 --> 03:18.310 We have rook G2. 03:18.310 --> 03:24.460 So once committed a lot resources and resources are shut in and seemingly seemingly quite silly looking, 03:24.460 --> 03:26.980 especially the knight on H three and a bishop on H one. 03:27.580 --> 03:30.100 So what does Black want to do here? 03:30.100 --> 03:33.640 These pieces look a little bit silly in particular. 03:34.390 --> 03:41.920 So black actually Alekhine plays dc4 and we have B to c four. 03:41.920 --> 03:46.420 The thing is, if Queen take C four, there's a very energetic move here. 03:46.420 --> 03:47.500 B five. 03:49.680 --> 03:56.280 And this spells some trouble if a times bishop takes up five this position. 03:58.830 --> 04:00.600 Why it's under real pressure here. 04:00.720 --> 04:05.880 And this is just very, very advantageous to win free and then win the exchange. 04:06.780 --> 04:08.520 So that's out of the question. 04:09.540 --> 04:10.560 And. 04:11.850 --> 04:12.150 Yeah. 04:12.150 --> 04:17.970 It looks as though because of be takes and Bishop takes a four and things like 95 this this is not looking 04:17.970 --> 04:19.260 good or excavating a rook. 04:19.260 --> 04:20.880 It's not good to take on C seven. 04:20.880 --> 04:31.050 So B takes C four was played and we have Bishop takes A for losing a pawn right off to Bishop D 792 04:31.080 --> 04:41.250 and now again on this side of the board B five we have 91 and now 93 offering whites the A five pawn 04:41.580 --> 04:46.950 rook takes a five and we have now B for rook takes eight. 04:46.950 --> 04:52.140 And guess what Alekhine plays here, which makes this game very special. 04:55.970 --> 04:58.880 So it's been playing on this side of the board after the King side. 04:58.940 --> 05:02.030 He actually just plays be tank free. 05:03.170 --> 05:07.580 So we have rook takes a white temporarily is material up. 05:08.090 --> 05:10.760 And the point here is believe it or not. 05:11.840 --> 05:12.720 For 100 points. 05:12.720 --> 05:13.710 What would you play here? 05:15.790 --> 05:16.090 Yeah. 05:16.120 --> 05:20.230 See, too, these nights are not very good at managing the past pawn. 05:20.320 --> 05:24.190 So this rook on for is given with check kh7. 05:24.190 --> 05:26.500 But now black is going to be queening. 05:26.500 --> 05:36.310 We have nine F to see one queening with check nine to f one and now night E one, two and now queen 05:36.310 --> 05:37.390 take C4. 05:37.480 --> 05:44.160 So an interesting imbalance, but White's pieces look rather silly squeezed on this side of the board. 05:44.170 --> 05:46.930 So we have rugby eight and now Bishop B five. 05:46.930 --> 05:51.520 So a concrete mass of queen takes F1 mating. 05:51.970 --> 05:58.180 So White sacrifices the exchange here and tries to open up the pieces with G four. 05:58.390 --> 06:04.090 We have nice f free tag, which leaves a very dangerous pawn around the white king. 06:04.540 --> 06:05.890 G takes her five at now. 06:05.890 --> 06:07.090 Queen E two. 06:07.870 --> 06:12.730 We have D five and now King G eight. 06:14.710 --> 06:15.550 H five. 06:15.550 --> 06:16.590 And our King H seven. 06:16.600 --> 06:20.290 It looks as though White's struggling to be able to move. 06:20.290 --> 06:23.650 We have e four that's taken nine times. 06:23.650 --> 06:25.630 E for Queen takes e four. 06:25.630 --> 06:28.810 The Queen is too much in this position for the rook and knight. 06:29.290 --> 06:29.920 D six. 06:29.920 --> 06:30.940 This looks very desperate. 06:30.970 --> 06:36.700 C takes F six again, very desperate looking G takes F six, rook D two. 06:37.150 --> 06:40.450 And now returning to the theme of past pawns. 06:40.480 --> 06:42.310 Guess what the queen plays here. 06:44.830 --> 06:46.810 OC Queen E two. 06:47.110 --> 06:49.360 So it's actually a simplifying combination. 06:49.660 --> 06:52.500 Can't take on DD six because of Queen G two mating. 06:52.510 --> 06:59.080 So we have rook takes E to this simplifies thou after king F2 to a winning king and pawn ending. 06:59.080 --> 07:02.260 So e take f one King takes f one. 07:02.590 --> 07:07.490 We have king G seven, King E two, King F seven, King E four. 07:07.510 --> 07:11.440 And this is just a winning king and pawn anyhow, of the D five check. 07:13.460 --> 07:14.150 Yeah. 07:14.270 --> 07:19.580 When it has to resign, it's just trivially going to be winning now with King F5 coming. 07:21.110 --> 07:23.690 So, for example, King D for. 07:25.020 --> 07:25.350 Can't. 07:25.350 --> 07:27.660 Five This is just trivially winning. 07:28.050 --> 07:36.930 Or this deep -- can be used to lure away the white king soon, or even here just default fall and 07:36.930 --> 07:38.490 just learn the king away. 07:41.070 --> 07:45.690 So we're for DD two and that's going to be winning, picking up the other pawn soon. 07:45.840 --> 07:49.580 So, yeah, a fascinating game. 07:49.590 --> 07:53.850 It shows play on both sides of the board how to overwhelm an opponent. 07:53.880 --> 07:58.950 It's like resources were kind of damaged in the defense on the king side. 07:58.950 --> 08:05.550 Initially they were misplaced and that created weaknesses on the queenside in effect. 08:06.030 --> 08:11.910 So White's position was not very well prepared for the queenside attack after. 08:12.420 --> 08:20.460 So this is one of Amazon anakin's favorite positional patterns before attacking was part of attacking 08:20.460 --> 08:25.340 chess to kind of overwhelm the opponents on both sides of the board. 08:25.350 --> 08:27.260 So I thought it's an interesting example. 08:27.270 --> 08:35.130 So Alekhine you wouldn't think as a traditional positional player, but sometimes his concepts do have 08:35.130 --> 08:38.820 great positional and and strategic considerations. 08:39.120 --> 08:41.310 Okay, so much.
