WEBVTT 00:01.170 --> 00:01.890 Hi there. 00:01.920 --> 00:06.030 In this lecture, we see Max against Alexander Alekhine In 1937. 00:06.030 --> 00:10.290 This is round 25 of the World Championship match default for Max. 00:10.290 --> 00:18.420 Oh, we have 96 C4 E 693 bishop before the names are Indian. 00:18.450 --> 00:27.740 The Rubenstein variation Ephraim Planck consuls Alexander Alekhine castles here Knight G Ito d5 a friend 00:27.750 --> 00:38.640 Bishop e7c tank five e tank d59g3 and the energetic c five not minding an isolated queens pawn. 00:38.640 --> 00:42.120 We have Bishop take C5 and they'll be four. 00:42.150 --> 00:47.190 Statistically, one is moving pawns on dart squares. 00:47.610 --> 00:54.090 The adjacent line squares are interesting to consider, especially ones near the king like D one. 00:54.720 --> 00:58.890 I've seen the game, so I'm just just making note of the square weaknesses. 00:58.890 --> 01:03.060 They could be invasion points and the king still in the center. 01:03.060 --> 01:04.800 Because of this elaborate development. 01:04.800 --> 01:06.270 The king is still in the center. 01:06.960 --> 01:08.220 So just bear that in mind. 01:08.220 --> 01:14.340 So here Alekhine actually plays a very energetic move which is D4. 01:15.090 --> 01:17.020 So not minding, swapping it. 01:17.040 --> 01:20.910 I say Queen's pawn for a potentially weak pawn on C free. 01:21.000 --> 01:25.440 But what does that get exchange to after we have B take C5. 01:26.040 --> 01:28.980 If E takes the E4, bishop takes D4. 01:29.040 --> 01:33.600 Knight G to this position is very unpleasant for white. 01:34.710 --> 01:40.770 For example, Bishop takes E3 this position there's we can insert Bishop takes F to winning a pawn. 01:41.880 --> 01:47.970 But if we look at this, if Bishop B2 there's a direct knight G4 attack on F2, the king is still in 01:47.970 --> 01:50.370 the center, so that's pretty nasty. 01:50.370 --> 01:51.360 What is white doing here? 01:51.360 --> 01:53.910 This my G4, this F5. 01:54.150 --> 01:57.570 Check this position here. 01:57.810 --> 01:59.580 It's just getting a huge advantage. 01:59.580 --> 02:07.530 Yeah this just vicious the attack so okay beating C5 is played and we have D tank C3. 02:07.530 --> 02:09.390 So is this pawn potentially weak? 02:09.720 --> 02:18.180 One thing to consider if queen takes the eight rook takes the knight e two black can play knight e4 02:18.240 --> 02:21.260 holding the pawn for a moment and then taking on C5 here. 02:21.300 --> 02:25.080 This position is in black favor slightly. 02:25.080 --> 02:26.940 This is a very comfortable position for black. 02:27.990 --> 02:29.490 Okay, so Queen C two. 02:29.490 --> 02:31.830 Can this pawn be swapped for anything? 02:31.980 --> 02:32.640 So no. 02:32.640 --> 02:35.460 Statistically, white's pawns on dark squares. 02:35.460 --> 02:42.870 We have adjacent light square weaknesses and it's just an absolutely ingenious little combination is 02:42.870 --> 02:46.320 played by Anakin here which. 02:46.990 --> 02:48.340 Is it staggering? 02:48.340 --> 02:49.630 Basically, it's amazing. 02:49.630 --> 02:52.810 Queen A5, Rook b1. 02:52.960 --> 02:56.380 And there's a key point here being made now. 02:58.100 --> 03:04.340 It looks as though isn't going to be rounded up and this Queen's unprotected. 03:04.730 --> 03:07.170 But Alekhine senses a danger here. 03:07.190 --> 03:19.640 Bishop D7 So this is looking at this diagonal and look at one Here we have Rook B frame if Bishop different. 03:19.760 --> 03:26.930 This is diabolical Bishop A4 and then C to check and this position to avoid losing rook blank is just 03:26.930 --> 03:28.850 losing the exchange here. 03:30.110 --> 03:34.790 And this is even better than taking the exchange immediately. 03:35.750 --> 03:37.430 So what would White do here? 03:38.120 --> 03:41.930 This losing the exchange is just so much better for black. 03:41.930 --> 03:48.830 Black could even crash through here on D one, which echoes actually the game in a way. 03:48.860 --> 03:51.020 So that is a wonderful variation. 03:52.410 --> 03:54.150 With huge trouble for white. 03:55.230 --> 03:58.560 So Rook B3 is played and this seems to run into a skewer. 03:58.560 --> 04:08.280 But the big butts and this is the ingenious bat has an alchemist queen take C free because he can't 04:08.280 --> 04:08.700 take the root. 04:08.700 --> 04:09.700 Now it's just queens hanging. 04:09.720 --> 04:12.450 Guess what he plays here for ten points. 04:13.110 --> 04:14.130 Make it 100 points. 04:14.130 --> 04:15.600 So black to play. 04:19.660 --> 04:20.170 Yeah. 04:20.170 --> 04:23.110 The common square DX one is amplified. 04:23.890 --> 04:24.550 Yep. 04:24.940 --> 04:25.510 One. 04:26.110 --> 04:26.750 Ouch. 04:26.770 --> 04:28.780 This is actually winning material for Black. 04:29.590 --> 04:33.610 So what's happened is an isolated queens pawn was swapped for a weak pawn, which is swapped for winning 04:33.610 --> 04:34.570 material on D1. 04:34.630 --> 04:35.930 It's amazing stuff. 04:35.950 --> 04:39.220 We have Bishop C-4 just to put that on the board. 04:39.340 --> 04:42.250 You know, if Rook takes B7, Queen D1 is checkmate. 04:42.940 --> 04:47.230 So, Bishop C4 and now, actually. 04:49.000 --> 04:51.880 We have 96 not rushing to take on B3. 04:53.560 --> 04:58.890 Bishop takes A6 B tanks my consuls and now Bishop takes P3 the exchange up. 04:58.900 --> 04:59.800 Thanks very much. 04:59.920 --> 05:10.030 Rook B ain't Quincy two and we have Queen D five e4, Queen B3, Queenie two, Queen B five Queen offering 05:10.060 --> 05:12.700 Queen Take C 595. 05:12.760 --> 05:16.300 And this is looking like a dangerous night with possibilities for white. 05:16.720 --> 05:19.750 So we have rook b one and now queen of forest played. 05:21.130 --> 05:25.570 Okay, so if H yeah, black's just taking on C one. 05:25.570 --> 05:30.100 So Queen F4 is about protecting C one Queen G4 is interesting. 05:30.100 --> 05:36.610 Looking for a checkmates it turns out g5 g6 Queen g5. 05:37.480 --> 05:43.540 Guess what Black can play here, which is just winning even though the Queen's unprotected and it looks 05:43.540 --> 05:48.100 to be some dangerous tactics here, Black's play has. 05:48.860 --> 05:49.370 Yeah. 05:49.520 --> 05:50.540 No, it takes E-4. 05:50.540 --> 05:51.260 It hits the queen. 05:51.260 --> 05:52.280 It protects the queen. 05:53.120 --> 05:56.420 If 97 check king, H.A. is important. 05:56.720 --> 06:04.220 So there's no Queen H six check of King G seven and Black is just winning her King G seven is entertaining 06:04.220 --> 06:06.680 a load of nonsense with Queen H sex check. 06:06.920 --> 06:07.460 Yeah. 06:07.580 --> 06:10.130 If you know we don't want to entertain this. 06:10.130 --> 06:15.500 If the king has to step out here because this is unfortunate. 06:15.650 --> 06:17.270 No, this is just a load of nonsense. 06:17.270 --> 06:21.410 And actually, it could just end up with a draw by pencil with precise playing. 06:21.500 --> 06:22.100 So. 06:22.100 --> 06:23.990 But yeah, the key move would be. 06:25.190 --> 06:26.330 That I mentioned. 06:26.600 --> 06:35.660 So, Queen Jeffrey, this sequence with 9/10, E, four and eight, the bishop can't quite get onto 06:35.660 --> 06:36.650 the title. 06:37.520 --> 06:39.800 Effectively, the queen is looking at the queen. 06:40.130 --> 06:41.150 Protecting the queen. 06:41.180 --> 06:41.780 Yeah. 06:42.290 --> 06:45.680 And the queen is about to take out E7 seven as well. 06:45.710 --> 06:47.780 If the queen moves to H six. 06:47.990 --> 06:50.150 So, yeah, fun stuff. 06:50.300 --> 06:55.550 So anyway, so Queen Joffrey, unfortunately for Max, is ineffectual. 06:57.990 --> 06:58.650 Tell me so. 06:58.650 --> 07:02.130 Kung fu is played by now. 07:02.130 --> 07:06.990 Neat little tiny think nine E4 to try and deflect the Queen away from our form. 07:07.260 --> 07:10.920 We have H4 just to put that on the board. 07:10.950 --> 07:12.840 Queen takes e4, Rook takes C one. 07:12.840 --> 07:20.430 So H4 we have rookie eight, Rookie one and now Queen C afraid that she might be in a more. 07:20.460 --> 07:25.560 It seems that is a more accurate move in 96 just looking at that pin to simplify. 07:27.030 --> 07:35.130 And if 97 check just rotates E seven and here taking out C one we've check and black is just winning 07:35.130 --> 07:35.580 her. 07:37.650 --> 07:42.780 You know any queen saints there's always always check anyway and it's just Tony winning for black so 07:42.780 --> 07:46.590 Queen C Fredo was was played rook D one night D2. 07:46.620 --> 07:50.490 This does three seems to be a forceful simplification rook Tasty. 07:50.490 --> 07:52.200 Two rook take C one check. 07:53.100 --> 08:01.290 King H two Queen C seven Rook d6 Rook c5 So with the France of rook thanks. 08:01.290 --> 08:05.750 F five But now we have yes, an ingenious little trap here. 08:05.760 --> 08:06.740 G Free. 08:07.830 --> 08:08.850 And you might think. 08:09.730 --> 08:13.420 Well, why can't blank just take on that five? 08:15.510 --> 08:18.410 That is actually a good move, as it turns out. 08:18.420 --> 08:19.910 But this is even better. 08:20.070 --> 08:25.530 I think if Rock takes a five, can you see why it plays here for ten points? 08:28.320 --> 08:28.500 Yeah. 08:28.500 --> 08:33.270 One, it's a little trick based on the background closing up that diagonal One is a little trick. 08:33.270 --> 08:33.870 Rookie sex. 08:33.870 --> 08:34.140 Yes. 08:34.140 --> 08:37.890 That sets up a trick to show the king rookie six hits the eight. 08:38.190 --> 08:41.010 But even here, you know, Rook takes. 08:41.030 --> 08:47.190 He thinks this position with Rook takes four to check and the work coming back to E to to be able to 08:47.190 --> 08:54.570 defend the back road check Black still is better here as well but it's a lot more work potentially than 08:54.570 --> 08:55.260 the game. 08:55.260 --> 09:03.090 So just tucking the rook away, rook and fight is played and that renews. 09:03.090 --> 09:08.250 Rook takes five as a key France so that is protected. 09:08.250 --> 09:10.650 And now F6 is played. 09:13.040 --> 09:19.160 We have cage free and now H5 trying to undermine that Knight Queen d2. 09:19.190 --> 09:20.960 H thanks g for Czech King. 09:20.990 --> 09:23.960 Thanks G for Queen f7. 09:23.960 --> 09:26.000 So that F6 enabled this. 09:27.590 --> 09:35.590 We have age five and now alcohol is a bit fed up with that night on a five and uses a simplifying tank 09:35.630 --> 09:38.030 tank route takes five. 09:38.960 --> 09:45.960 So yes he's picking up now H five Quidditch for Czech Quidditch free. 09:45.980 --> 09:47.660 Czech Rookie. 09:47.660 --> 09:48.500 Eight Czech. 09:49.670 --> 09:51.110 Queen bee free check. 09:51.680 --> 09:53.420 And those taking out this --. 09:53.420 --> 09:58.160 And here once resigns, Max resigns here. 09:58.490 --> 10:05.400 A fascinating game, a really interesting swamp conversion of one thing to another. 10:05.420 --> 10:13.280 In the opening, actually, we see that the isolated queen's -- is turned into something else here. 10:13.310 --> 10:18.110 It's transformed into something else, a double edged, you know, seemingly loose form, which has 10:18.110 --> 10:24.320 turned into something else, you know, a way of winning material based on this amazing skewer combination 10:24.440 --> 10:27.140 in a way to see this retreat. 10:27.140 --> 10:31.310 Queen Diane, It's intriguing. 10:31.310 --> 10:33.350 It's just absolutely intriguing, this take. 10:34.790 --> 10:40.220 So looking at Dwan, yeah, statistically we can say, well, maybe intuitively, if the if the opponent's 10:40.220 --> 10:44.990 pawns are on a certain color, look, on the other hand, how you can join forces on the other color 10:44.990 --> 10:45.650 basically. 10:45.650 --> 10:51.200 But yeah, it's concrete calculation and the Queen is a fantastic calculator. 10:51.890 --> 10:58.700 But yeah, it's just very interesting, this tactical combination to win material in a world championship 10:58.700 --> 10:59.210 match. 10:59.330 --> 11:00.200 Okay. 11:00.860 --> 11:02.990 I hope you got some constructive points from that. 11:03.740 --> 11:04.490 Thanks very much.
