WEBVTT 00:00.930 --> 00:01.830 Hi there. 00:02.070 --> 00:08.170 In this lecture, Alexander Alekhine is playing against Oskar Chinese in 1911, the Colonel's battlements. 00:08.190 --> 00:08.880 So we see. 00:08.910 --> 00:12.360 C4 from Alekhine e6 e4. 00:12.390 --> 00:15.600 Now there is an Achilles heel structurally d4. 00:15.630 --> 00:17.040 Just bear that in mind. 00:17.250 --> 00:22.350 We see C5, which marks that square 9396. 00:22.350 --> 00:24.330 Planck's play so far is logical. 00:24.900 --> 00:25.980 Except here, knights. 00:25.980 --> 00:30.360 Every black should be concerned about D4 here. 00:30.390 --> 00:36.810 Black plays actually G6 creating a collection of dot square weaknesses around the place. 00:37.380 --> 00:39.420 This is a bit of a luxury move. 00:39.960 --> 00:47.790 Instead, e5 even though the pawn has gone to E6 and this seems to be a wasting a move, it locks down 00:47.790 --> 00:48.660 D4. 00:48.690 --> 00:50.310 It's got a safety point to it. 00:50.700 --> 01:00.900 If g3 d6 d3 g6 it's like a botvinnik system of the English opening, but it's about equal here in a 01:00.900 --> 01:01.560 technical sense. 01:01.860 --> 01:06.090 This should be equal, but with G6, horrible things happen. 01:06.090 --> 01:15.990 Now we see D4 opening up those darts square weaknesses and if it's ignored there's the possibility of 01:15.990 --> 01:16.520 D5. 01:16.530 --> 01:23.850 So we have C takes D4 Knight 64, Bishop G seven and look at D6 here. 01:24.210 --> 01:33.030 If Knight takes D4, Queen takes f6, there's Bishop A4 here and if Black plays E5, this bishop takes 01:33.030 --> 01:36.090 E5 and this is very nice for white to win the rook. 01:36.420 --> 01:40.500 So let's imagine Knight H6 instead. 01:41.070 --> 01:49.890 Queen D2 one has the advantage here, but Ock Bishop G seven was played Knight DB five and then Bishop 01:49.890 --> 01:50.670 e5. 01:51.840 --> 01:54.850 If Black had played Knight G seven funny enough. 01:54.870 --> 01:57.360 Can you see what strong in this position? 01:58.390 --> 01:59.650 What's really strong. 02:01.480 --> 02:02.740 We can do better. 02:02.740 --> 02:08.140 It seems with 96 check we can do actually back with Bishop A4 if Black Castle. 02:08.230 --> 02:12.880 The point is Bishop C7, then we're going to checkmate the Queen based on the D6 square. 02:13.210 --> 02:14.140 So that's funny. 02:14.140 --> 02:22.570 Anyway, so and here if E5 then 96 Jack and Bishop E4 is great for White, so okay, we have Bishop 02:22.570 --> 02:26.950 E5 F4 trying to nudge the bishop away. 02:28.720 --> 02:30.430 It's such a strong position already. 02:30.430 --> 02:32.290 96 check was also possible. 02:32.290 --> 02:35.890 This position is actually rather dominant with this move order. 02:36.220 --> 02:42.440 So for example, here we can pen the A6 pawn and actually just celebrate a knight on D6. 02:42.440 --> 02:43.540 It doesn't matter about B2. 02:43.570 --> 02:47.830 This is a phenomenal position to get bigger vantage point. 02:47.840 --> 02:55.990 So anyway F for here majorly A6 and F takes E5 eight and now Bishop F4. 02:57.670 --> 02:59.560 Yeah, it's an interesting position. 02:59.770 --> 03:00.880 Lots of options actually. 03:00.890 --> 03:03.400 Knight takes B5 was was possible as well. 03:03.610 --> 03:12.910 Even this route where White loses a rook is not so clear for black here because Bishop F4. 03:14.200 --> 03:17.150 And the queen's kind of a prisoner here. 03:17.170 --> 03:17.860 What's going on? 03:17.890 --> 03:22.340 Castle Queenside and Bishop G2 winning in the Queen so nicely for his desperate move. 03:22.360 --> 03:24.070 But White's just better that. 03:24.220 --> 03:27.220 And if Knight G7 instead. 03:27.230 --> 03:30.640 Not G7, you know, we just castle with Bishop G2 in mind. 03:31.980 --> 03:32.760 Soon. 03:33.480 --> 03:36.720 And in fact, even more accurate, is Bishop H free? 03:37.410 --> 03:38.530 Not without H two. 03:38.550 --> 03:39.720 So here, Bishop H. 03:39.720 --> 03:40.170 Freeh. 03:40.170 --> 03:42.690 And we're winning the Queen without Queen since H two. 03:44.640 --> 03:47.430 So this position is better for Y. 03:47.460 --> 03:51.090 So it's funny stuff about 1965, it seems, is plausible. 03:52.950 --> 03:56.790 Also, you know, just to show how strong possession is, queenly sex is dangerous. 03:56.790 --> 03:59.850 This possession is also kind of good for white. 04:00.690 --> 04:02.400 Yeah, blacks misplayed the opening. 04:02.400 --> 04:07.170 So anyway, we have Bishop F for B taxi for bishop. 04:07.170 --> 04:11.640 Take C for rook e5 wine castles. 04:13.830 --> 04:15.930 And yeah, there's a world of pain here. 04:16.230 --> 04:18.690 On the dark squares, the bishop's just ready to play. 04:18.690 --> 04:20.520 Bishop H six, F nine, G seven. 04:20.730 --> 04:23.730 There's lots of interesting moves here, in fact. 04:24.570 --> 04:25.470 So. 04:26.720 --> 04:36.200 We have actually be five and now be4 if Bishop be free before one can actually throw in 95 with the 04:36.200 --> 04:37.590 king still in the center. 04:38.280 --> 04:43.760 So it is just liberates the whole wide position here and is a big advantage. 04:43.760 --> 04:48.260 This position is also you know it's just an overwhelming position cracking open. 04:48.260 --> 04:51.560 The position with the king and the center is a nice recipe. 04:51.740 --> 04:55.430 And, you know, this is just devastating here. 04:55.430 --> 05:02.030 For example, if a queen bring the king back for queen, the eight track queen is main. 05:02.270 --> 05:04.580 So, yeah, there's lots of interesting stuff. 05:04.760 --> 05:11.810 Even Bishop be free for 95 is great but before was plate we have Queen bees six check. 05:14.100 --> 05:22.320 If Knight takes before Knight takes B5 and it doesn't actually matter at this check, if Rook takes 05:22.320 --> 05:28.890 P5, we can take here and hit this position, pin the knight and look at look at Black's pieces. 05:28.890 --> 05:29.830 They're ridiculous. 05:29.850 --> 05:33.750 This is just a ridiculous situation where Black has to give back the piece, basically. 05:33.750 --> 05:35.880 And White's in a commanding position. 05:36.030 --> 05:44.280 So anyway, Queen Bee six Champ was played nine times before here, and yet it's a similar scenario. 05:44.310 --> 05:51.150 Bishop takes B5 where we're getting a pin out of this Knight takes Queen where Black's again, not in 05:51.150 --> 05:58.440 a great position to do anything about the pin Bishop e6 is tried If queen a five we can amplify the 05:58.440 --> 05:58.670 pen. 05:58.690 --> 06:00.750 Bishop d2 and this is just great. 06:00.780 --> 06:03.030 Bishop takes b4 so yes. 06:03.030 --> 06:03.780 And if Queen. 06:03.810 --> 06:06.990 C for sure. 06:07.380 --> 06:08.200 Queen Rook. 06:08.200 --> 06:11.400 C one this queen a6 protecting A6. 06:11.520 --> 06:17.850 But we can just amplify the pin with Queen A4 here and getting commanding position there. 06:18.120 --> 06:20.460 So anyway, Bishop A6 was played. 06:21.150 --> 06:25.080 We have Queen D6 now. 06:27.200 --> 06:36.340 F thinks if my e7 rook have D1 and if Cos then Queen takes E7, we're looking forward to a dot square 06:36.350 --> 06:40.550 tonight with Queen of Sixth and Bishop 86 as well as winning that piece on B4. 06:40.970 --> 06:46.310 So okay, so F6 was tried Rook FC one. 06:47.060 --> 06:50.000 So this frees up the rook now without being mated. 06:50.030 --> 06:53.090 If rook takes b4 then queen f1 is mate. 06:53.730 --> 06:53.960 Yeah. 06:53.990 --> 07:02.390 So rook FC one queen D3 and now just rook takes before we have G5. 07:02.420 --> 07:02.750 Yeah. 07:03.110 --> 07:04.560 Black's opening is terrible. 07:04.580 --> 07:05.810 Here's the nightmare. 07:06.170 --> 07:13.070 If Queen takes D6, then this is also it's just the exchange down basically with a lost position. 07:13.070 --> 07:15.410 And even Rook C seven is winning here. 07:15.440 --> 07:17.630 This position is so strong for white. 07:17.810 --> 07:21.470 For example here, what is black doing about this pawn? 07:21.590 --> 07:22.520 Not much. 07:22.880 --> 07:23.590 It's terrible. 07:23.600 --> 07:33.020 So G5 is tried, but now rook D4 looking at D7 so tempo and I'm trying to nudge the queen away from 07:33.020 --> 07:33.710 D7. 07:34.550 --> 07:34.930 Okay. 07:34.940 --> 07:43.670 Queen V7 and now Rook c seven not minding this checkers of Rook D one and here black resigned if Queen 07:43.670 --> 07:48.320 B eight Queen 67 check and Queen F seven is checkmate. 07:48.710 --> 07:51.420 Now, this is kind of instructive. 07:51.440 --> 07:56.330 Like with Paul Morphy games, often they're very instructive because the opponent made some mistakes 07:56.330 --> 08:02.810 which often occur at the the average player level, which you know is less than 2200. 08:03.440 --> 08:08.210 But this is like a typical mistake creating too many dot square weaknesses. 08:08.210 --> 08:15.890 So we see that actually, even if we had been planning on a botvinnik system with different Geoffrey, 08:16.190 --> 08:22.690 that structure, you know, accepting D4 as a weakness, this is a special circumstance where D4 here 08:22.940 --> 08:31.760 is very powerful indeed very, very, very strong, very dangerous position for black to be in. 08:32.210 --> 08:38.690 So, yes, when it opens up like this, we're getting a semi-open file, which is enabling us to exploit 08:38.690 --> 08:44.970 much more easily these dot square weaknesses such as D6 and Black's camp as we see here. 08:44.990 --> 08:48.230 This is a major issue that's D6 square. 08:48.590 --> 08:50.660 So it's very interesting stuff. 08:50.690 --> 08:52.550 How to expose weaknesses. 08:53.090 --> 08:56.000 I hope you enjoyed this game and so much.
