WEBVTT 00:00.810 --> 00:01.620 Hi there. 00:01.650 --> 00:08.250 In this lecture, we see Roginsky against Alexander Alekhine in a 1913 exhibition game. 00:08.730 --> 00:18.420 So e4 from was scheme and Alekhine plays e5 We have lighter three d sex so the Philidor defense, Bishop 00:18.450 --> 00:23.010 C4 Knight, C6 C3 and now Bishop G4. 00:23.040 --> 00:25.770 This isn't really a recommendable move. 00:26.040 --> 00:29.460 We have to ignore Alekhine's opening sequence here. 00:29.700 --> 00:36.360 The weakness of the last move b7 is actually exploitable fully here, it seems, because it has made 00:36.360 --> 00:38.610 way for the Queen to use B3. 00:38.610 --> 00:46.500 So hitting F7 and B7 big trouble for black hair in a theoretical sense. 00:46.500 --> 00:55.230 Annacone plays Queen d7g5 is played if Queen size b71 should be getting a clear advantage. 00:55.230 --> 01:06.840 This position behind Queen a6 note f6 as long as White's plays accurately were moved like d three This 01:06.840 --> 01:09.420 position not minding the double pawns. 01:09.420 --> 01:16.380 Why is better here If white indulges Bishop B five, then there's rook B six queen A4 and actually black 01:16.680 --> 01:22.230 can equalize now from the poor opening, can you see how for five points? 01:24.700 --> 01:29.830 It takes EA four to try and drag the Queen away from the Bishop de force. 01:29.870 --> 01:34.280 Even Bishop thinks is just bad for black queen tanks. 01:34.280 --> 01:35.840 And this is bad for black. 01:38.100 --> 01:45.170 Okay, so anyway, Night G5 is suboptimal as a way of punishing Alekhine's opening play. 01:45.230 --> 01:48.710 We have no H6 and now Bishop takes F7. 01:48.740 --> 01:53.120 This is suboptimal Hare Queen thanks B seven Hair B eight. 01:53.120 --> 01:54.020 Queen 86. 01:54.020 --> 01:55.680 Bishop E seven. 01:55.730 --> 02:01.760 The frame protecting the Bishop h5 is an advantage for white. 02:02.830 --> 02:02.950 Yeah. 02:03.040 --> 02:04.150 Even then, the Queen's offside. 02:04.150 --> 02:05.770 This is an advantage for white. 02:06.220 --> 02:09.700 But why instead indulges Bishop takes up seven check. 02:09.700 --> 02:10.520 9/10. 02:10.540 --> 02:11.530 9/10. 02:12.070 --> 02:13.780 Queen Saints have seven. 02:14.660 --> 02:17.960 Which seems like maybe an unexpected. 02:19.220 --> 02:27.190 Well, it's a move which looks, you know, rather expected to to win B7 and win the peace back. 02:27.200 --> 02:28.610 That's the expectation. 02:30.560 --> 02:31.550 So Queen takes. 02:31.550 --> 02:32.600 Yes, it neglects. 02:32.600 --> 02:35.780 There's a weakness of the last move, it seems that neglects C6. 02:35.780 --> 02:37.340 So a queen takes B seven. 02:37.340 --> 02:40.970 What could possibly go wrong here for white in this position? 02:41.300 --> 02:42.110 So. 02:43.150 --> 02:43.570 Yeah. 02:43.570 --> 02:49.150 I mean, Black actually has two strong moves here, but played a very, very nice way. 02:49.180 --> 02:55.750 One of the strongest King D7 There's also Rook D eight just letting C six go black has enough hair. 02:58.160 --> 02:59.140 Of the queen sex. 02:59.150 --> 03:03.920 There's enough compensation hitting E4 and G to the thing with the C free move in this case. 03:04.130 --> 03:09.860 You know, these pieces are still all asleep in bed hangover after a party. 03:09.860 --> 03:16.440 Because if one cancels Bishop H for him, we can actually do more damage than just winning in exchange. 03:16.460 --> 03:18.020 Let's say check here. 03:18.320 --> 03:20.240 Check King seven G. 03:20.450 --> 03:21.500 What would you play here for? 03:21.500 --> 03:22.370 100 points. 03:26.050 --> 03:27.760 Remember, all of these pieces are asleep. 03:27.760 --> 03:29.950 They're piece pieces in this variation. 03:30.430 --> 03:35.890 We can actually play Queen sex e4 Checkmate, and the game ends the war. 03:35.920 --> 03:37.690 You know, winning material is just winning a battle. 03:37.720 --> 03:38.650 Bear that in mind, sir. 03:38.650 --> 03:39.940 Queen takes E4. 03:40.480 --> 03:45.520 So that's why it's sometimes very good to always look for a stronger move, more sort of war ending 03:45.520 --> 03:47.320 moves rather than battle winning. 03:48.250 --> 03:55.810 So every queen eats who is mating Her rook have two queen E one check queen F1 is mate. 03:55.840 --> 03:58.630 So in other words, rook t is actually a good move. 03:58.630 --> 04:00.520 It's actually leading to advantage for Black. 04:00.520 --> 04:03.010 White's completely mishandled the advantage. 04:03.160 --> 04:06.640 But King D7 is played and that's also a good move. 04:06.880 --> 04:14.170 Queen takes ain't the Queen's in Siberia here the king now is in trouble. 04:14.650 --> 04:21.450 So first Queen C4 with the France of a mate in one that's pretty concrete and three bishop tanks at 04:21.460 --> 04:22.600 three G tanks. 04:22.600 --> 04:24.460 Just for the record here. 04:24.490 --> 04:24.760 Yeah. 04:24.790 --> 04:27.520 Bishop takes that phrase one of the best practical tries. 04:29.050 --> 04:34.240 And if, for example, Bishop e6 y has my say three. 04:35.340 --> 04:36.570 And this is really annoying. 04:37.080 --> 04:40.080 If Queen 86 b4 Queen b6 eight. 04:40.110 --> 04:43.560 This is just winning for one actually of the 92. 04:43.560 --> 04:46.920 Why it is why it has king safety emerging. 04:47.520 --> 04:50.130 So yes, Bishop E6 is actually not very good. 04:52.560 --> 04:55.920 And also, of course, it has the luxury of King F2 as an option. 04:55.920 --> 05:07.920 So yeah, Bishop E6 is losing Bishop H 593 this position as an example b4 and here rook b1 is dangerous 05:07.920 --> 05:14.310 for White's queen after rook be free this position one could end up losing the Queen, so it's important 05:14.310 --> 05:18.690 to play accurately this then as Bishop B to winning the Queen. 05:20.010 --> 05:21.810 Bishop H phrase another shot. 05:21.810 --> 05:30.510 Actually, if King F2 bishop takes G2 and Black's going to be doing really well here, this position 05:30.540 --> 05:38.340 likes doing really well because, for example, this attacks the queen and then queen takes her free. 05:38.340 --> 05:40.620 Black can use the F4 and is winning there. 05:40.980 --> 05:45.020 These pieces are still asleep and the queen's in Siberia. 05:45.030 --> 05:47.580 So yeah, what could be expected? 05:49.500 --> 05:51.720 So in that line, Bishop takes G2. 05:51.750 --> 05:52.590 Yeah, that's. 05:52.590 --> 05:53.610 That's dangerous. 05:54.840 --> 05:59.880 If we go back here, though, and say that black doesn't. 06:00.480 --> 06:03.870 Yeah, I mean that that is really dangerous. 06:03.870 --> 06:04.200 But. 06:05.430 --> 06:14.880 King F2 but knowing A3 here instead this position with G takes in this position it's tricky. 06:14.880 --> 06:25.340 There's 92 funny enough and Queen St C2, Queen B seven, Queen B3 White's getting an advantage there. 06:25.350 --> 06:27.840 It's just murky waters, basically. 06:28.260 --> 06:32.040 So Bishop H has murky waters after night a free. 06:32.070 --> 06:36.750 You know, White's not obliged to play king after allowing Bishop takes G2. 06:36.990 --> 06:41.310 So we're actually gathering evidence for the strength of the Queen's move. 06:41.310 --> 06:47.130 Another possibility was 94, but the free hand. 06:48.110 --> 06:53.720 And now if meetings are free, Gee takes Queen 63 as Queen D five. 06:54.230 --> 07:01.720 And this leads to a situation which is essentially a perpetual check drawer. 07:01.760 --> 07:06.530 It's funny, you know, because it has resources like it's a fat train. 07:06.530 --> 07:11.690 But yeah, this this is a perpetual check situation. 07:12.590 --> 07:16.610 If King E seven, Bishop G five check. 07:17.000 --> 07:23.270 And again, we're back to No, we don't have to play the checks now upon me. 07:23.300 --> 07:24.410 So it's not perpetual change. 07:24.590 --> 07:26.560 We just pay as white Queen F one. 07:26.570 --> 07:27.920 It's awkward stuff. 07:28.100 --> 07:29.690 It's really crazy stuff. 07:30.140 --> 07:35.870 But yeah, we get an appreciation if we look at all of these other possibilities that we get an appreciation. 07:36.170 --> 07:45.800 This is very nice, practical trying because it's really damaging the resource capacity on this diagonal 07:46.100 --> 07:51.260 for playing a move like G free by chipping that out, weakening this diagonal. 07:52.010 --> 07:54.200 So, yes, a very, very nice practical move. 07:54.230 --> 07:55.500 Bishop takes her free. 07:55.520 --> 07:57.890 So let's continue the game from here. 07:57.920 --> 07:59.330 G takes our three. 08:01.300 --> 08:02.870 And now another concrete move. 08:02.890 --> 08:04.210 What would you play here? 08:07.350 --> 08:08.340 For ten points. 08:18.390 --> 08:18.720 Okay. 08:18.720 --> 08:19.590 94. 08:19.590 --> 08:19.810 So. 08:19.860 --> 08:20.940 Fractions, mate. 08:21.180 --> 08:22.650 Now, White makes a big mistake. 08:22.650 --> 08:23.100 D3. 08:23.250 --> 08:27.540 It should have played C takes D4 and trade off some material for King safety. 08:27.540 --> 08:30.720 This position is actually funny enough. 08:32.040 --> 08:36.720 Even the engines have this position is even of the B4. 08:38.370 --> 08:47.970 Yeah, because Queen thanks H to King D one Queen G one King C two and yeah, the b4 pawn actually covers 08:47.970 --> 08:52.560 the C5 square used for it and that bishop is kind of pin this is an even position. 08:52.560 --> 09:02.790 But instead after 94 won't play D3 which where creeping into a mating combination elements of a mating 09:02.790 --> 09:09.360 combination here because after Queen takes D3, the Queen is covering even more escape squares than 09:09.360 --> 09:10.170 before. 09:11.980 --> 09:13.500 So we have C 64. 09:13.510 --> 09:14.270 But now guess what? 09:14.290 --> 09:15.460 Our crime place. 09:19.560 --> 09:20.370 Bishop seven. 09:20.370 --> 09:20.820 Yeah. 09:21.270 --> 09:23.850 It's hitting the Queen and threatening. 09:23.850 --> 09:25.560 Make your hair very concrete. 09:26.490 --> 09:33.030 So Queen St's ain't st Bishop h4 Champ mates if 92 instead. 09:33.030 --> 09:33.240 Yeah. 09:33.240 --> 09:34.680 We're just going to take the Queen. 09:35.010 --> 09:35.360 Okay. 09:35.370 --> 09:41.070 This is not champ mate because of King D1, but we're just going to take the Queen and you know it's 09:41.080 --> 09:43.410 subsidy winning for black, this position. 09:44.280 --> 09:45.840 So yes, funny stuff. 09:45.870 --> 09:51.630 A funny game 15 mover I alekhine I completely misplayed his opening actually. 09:52.200 --> 09:55.980 But the resources in chess are quite rich. 09:57.120 --> 09:58.610 We're not all supercomputers. 09:58.620 --> 10:04.110 So yes, we're wrong here with especially nine takes F seven. 10:04.830 --> 10:09.450 Well, this whole concept of bishop upon me, the whole concept of bishop takes up seven. 10:09.460 --> 10:12.330 It's leaving one weak on the line squares, actually. 10:12.360 --> 10:13.890 Fundamentally, if you think about it. 10:15.540 --> 10:18.270 So, yes, Queen size seven was very important here. 10:18.720 --> 10:23.880 So in the game, yeah, once kind of left like abandon these light squares, especially the see four 10:23.880 --> 10:24.600 points. 10:25.740 --> 10:27.450 And so this is just great news. 10:27.450 --> 10:29.850 This is really a great news. 10:30.150 --> 10:32.580 One has to play accurately just to stay in the game. 10:34.190 --> 10:37.130 So every. 10:39.410 --> 10:42.990 And then the bishop takes that very, really brutal stuff actually from Alekhine. 10:43.040 --> 10:50.690 So it is really nice how he recovered from the bad opening, very provocative opening and actually casting 10:50.690 --> 10:55.460 a big shadow on all the consensus of whites materialism. 10:55.790 --> 10:58.910 Basically, the light squares, the king in the center. 10:59.420 --> 11:04.210 And if you think about it, this is a variation of the Boden's mate with the queen is substituting for 11:04.250 --> 11:04.860 a bishop. 11:04.880 --> 11:07.460 Well, it's also God in curse capes where says. 11:07.940 --> 11:11.480 It's just it's just a made pattern with bishop and queen. 11:11.990 --> 11:13.330 So really, really nice. 11:13.340 --> 11:22.040 I think that's what makes Alekhine really fun to me because his play has emerged, it seems, from beautiful 11:22.220 --> 11:26.780 mating combinations, and that's one of my absolute favorite type of combinations. 11:26.780 --> 11:32.360 In general, they are, you know, war ending combinations, not just battle ending combinations like 11:32.360 --> 11:33.260 winning material. 11:33.410 --> 11:41.570 So, yeah, this whole game is fantastic for this build up for this mating combination, in my view. 11:41.570 --> 11:43.220 I hope you've enjoyed it as much as me. 11:43.460 --> 11:52.070 So we see some of the mechanics involved here ripping open the king cover and care scape squares ready 11:52.070 --> 11:52.880 to pounce. 11:53.090 --> 11:55.460 Okay, that's very much.
