WEBVTT 00:00.810 --> 00:01.680 Hi there. 00:01.710 --> 00:05.650 In this lecture, let's have a look at the so called immortal game. 00:05.670 --> 00:07.830 This has stood the test of time. 00:07.830 --> 00:14.100 It was playing between and of Anderson and Lionel Kieseritzky in 1851. 00:14.100 --> 00:18.660 It's just a casual game, but it stood the test of time being so absolutely brilliant. 00:18.930 --> 00:22.350 So it's one of the all time attacking classics. 00:22.500 --> 00:26.280 It has been featured in the 1982 Blade Runner film. 00:26.280 --> 00:33.120 So if you're a fan of sci fi, that's a major sci fi film worth checking out and all versions of Blade 00:33.120 --> 00:33.630 Runner. 00:33.630 --> 00:36.600 So who is Alf Anderson? 00:36.600 --> 00:40.170 So this is a little bit of history you can get at Wiki. 00:40.200 --> 00:46.830 He was one of the strongest players of his day and regarded by some to be the world champion after his 00:46.830 --> 00:50.250 victory in the in the London 1851 tournament. 00:51.060 --> 00:56.940 However, he lost the honor in the Anson Morphy 1858 match. 00:57.480 --> 01:03.180 One year later, when Paul Morphy retired from International Chess, Anderson was able to regain his 01:03.180 --> 01:12.780 reputation as one of the world's leading players, drawing with Polish in 19 in 1860, pardon me, and 01:12.780 --> 01:15.330 winning Anderson College in 1861. 01:15.330 --> 01:19.200 And then he went on to win the London International 1862. 01:21.610 --> 01:23.110 And that was over. 01:23.980 --> 01:26.650 You know, Louis Poulsen was in that finished second. 01:27.190 --> 01:34.210 So, yeah, he's got this great set of victories, basically after Paul Morphy left the scene so he 01:34.210 --> 01:39.310 could be regarded as another kind of unofficial world chess champion, a bit like Paul Morphy, and 01:39.310 --> 01:42.820 he's regarded as the quintessential romantic. 01:44.270 --> 01:47.690 With his sacrificial brilliancy, such as the game we about to see. 01:47.690 --> 01:54.140 So the romantic era of chess where it was fought to be a bit ungentlemanly, not to accept sacrifice 01:54.140 --> 01:56.980 material as if you're a bit cowardly or something. 01:56.990 --> 01:59.000 So okay, let's see this game. 02:00.050 --> 02:08.570 E4 From end of Anderson, we have E5 come from Kieseritzky for The King's Gambit, so this is a powerful 02:08.570 --> 02:13.940 icon of the romantic era of The King's Gambit, and Boris Spassky in later generations took it up with 02:13.940 --> 02:15.290 great success as well. 02:16.070 --> 02:25.250 So we have E2, F4 and now Bishop C4, usually Knight F3 is played here, but this is another variation 02:25.250 --> 02:27.540 which is very, very interesting with Bishop. 02:27.560 --> 02:29.930 C4 Knight Free Gods the age for square. 02:30.080 --> 02:35.900 So Bishop C4, the Queen does use that invitation to use h4. 02:36.500 --> 02:41.540 Black could have played Knight C6 this position for example. 02:41.570 --> 02:42.410 Slight difference. 02:42.410 --> 02:50.300 Black should be with a technical advantage, but engines are having difficulty with these such situations. 02:50.420 --> 02:53.450 There is a balance between material and king safety. 02:53.960 --> 02:59.450 If we look also here at Knights F3, Black could consider G5. 03:00.230 --> 03:05.210 Okay, so anyway, Queen H for check, we have King F1 B5. 03:05.210 --> 03:08.570 So this was actually a favorite move of Kieseritzky. 03:08.570 --> 03:16.490 Apparently this kind of gambit pawn we have you know if these sex here 93 nine f6 this is another way 03:16.490 --> 03:22.550 of playing it and black should be technically okay but B5 this spice things up a little bit. 03:24.080 --> 03:31.130 Bishop thanks B5 we have nice f69 F3 and now Queen H six the free. 03:32.910 --> 03:33.930 Interesting. 03:34.440 --> 03:36.910 Different is actually pretty interesting. 03:36.930 --> 03:37.740 Alternatives. 03:37.920 --> 03:42.000 If D for sure blank would actually consider taking on E4. 03:43.050 --> 03:49.560 And you know there are threats like night g free shark here this looks you know who's king is unsafe 03:49.560 --> 03:56.490 here like g free to try and win the rook but Queenie to F5 this position now is actually rather interesting 03:57.120 --> 03:59.250 A better move might be knight C free. 03:59.250 --> 04:06.630 In fact, this is another way of protecting E4, but it also offers, if we look at this E5 nine, g 04:06.630 --> 04:11.940 four and now nine E4 protects F2 hits the bishop. 04:11.940 --> 04:21.780 This kind of situation with beef, all this is weird and wonderful, but it should offer up to 95 Knight 04:21.780 --> 04:22.590 D six check. 04:22.590 --> 04:26.700 This should offer a very interesting position for white with maybe a small edge. 04:26.700 --> 04:28.140 It's it looks chaotic. 04:28.140 --> 04:28.950 It looks like a mess. 04:28.950 --> 04:31.620 But yeah there's some interesting lines with knight C free. 04:31.620 --> 04:38.400 But anyway D3 was played We have Knight h5 so the format here is Knight G Free shank. 04:40.590 --> 04:47.550 Essentially, if C six had been played and the bishop drops back, this looks to be about even actually 04:47.550 --> 04:49.140 with Knight G4 here. 04:49.180 --> 04:55.500 93 bishop afterwards be annoying and bishop if it should be about even black does have that free control 04:55.500 --> 04:58.860 with the Queen justifying itself in this variation on age sex. 04:59.130 --> 05:08.760 So anyway, 95 we have no teach for Queen G five and you can see that this is actually attacking both 05:08.760 --> 05:09.540 pieces. 05:09.900 --> 05:18.210 So we have this move Knights F five, C six and now G for countering threat to a piece of offensive, 05:18.210 --> 05:20.330 a piece G for that pawn being pinned. 05:20.340 --> 05:22.320 There's no point without losing the Queen. 05:22.470 --> 05:23.520 We have nothing to have sex. 05:23.520 --> 05:27.180 Rook G one So this is where it absolutely gets amazing. 05:27.840 --> 05:30.270 So rather than move the bishop. 05:31.290 --> 05:36.450 Which does give blank the option of night takes G4 which could be annoying. 05:38.900 --> 05:41.190 Whole bishop is sacrificed and this makes the game. 05:41.190 --> 05:43.020 It starts to make the game absolutely amazing. 05:43.020 --> 05:45.150 So a whole bishop sacrifice here. 05:45.630 --> 05:50.640 But you can see one consideration to make here is about the position, not just the material. 05:53.100 --> 05:57.560 And you know, you can balance when you evaluate positions. 05:57.570 --> 06:02.880 It's like king safety versus interior and often pawn structure versus piece activity and all four of 06:02.880 --> 06:06.900 those elements to be key elements to evaluate any position. 06:07.260 --> 06:12.030 But of course there are other elements like having the bishop pair of bishop without a counterpart are 06:12.030 --> 06:13.740 the elements we've discussed in this. 06:13.740 --> 06:19.800 Sections of this course are all ingredients, but here a key ingredient cropping up is essentially material 06:19.800 --> 06:21.090 versus king safety. 06:21.090 --> 06:27.030 But what's happening is that once pieces are getting developed and Black's pieces are still asleep, 06:27.930 --> 06:30.690 especially these rooks, these guys are still on the back row. 06:30.690 --> 06:38.100 So the quality of pieces after this piece, sacrifice is in its favor position, you could say also 06:39.000 --> 06:40.140 versus. 06:41.520 --> 06:42.210 Material. 06:42.210 --> 06:47.090 So material being offered for possession or or you could say KING Safety first all. 06:47.130 --> 06:53.160 But actually the position itself, just intuitively, one should feel there are a lot of these spectator 06:53.160 --> 06:54.540 sleeping pieces here. 06:54.570 --> 06:58.470 The position for why seems absolutely great. 06:59.640 --> 07:05.850 So Queen G five Queen are free and it looks as though this pawn is going to win on the tempo and black 07:05.850 --> 07:08.760 goes back to let the Queen have some escape squares. 07:08.880 --> 07:11.700 So the position is getting even more dominant. 07:12.750 --> 07:17.790 That's a fantastic thing to liberate one's chest, just to look visually. 07:17.880 --> 07:22.110 We don't have to just regard on what computers say about positions. 07:22.110 --> 07:29.130 If, you know, they classically have favored the signs with great material because computers have to 07:29.130 --> 07:31.890 calculate further and further to justify the material. 07:31.890 --> 07:38.070 But as humans, we can say, well, blacks really on a back foot, literally in a funny back foot with 07:38.070 --> 07:43.200 all of these pieces on the back row, blacks really on the back foot here, Bishop takes her for Queen 07:43.360 --> 07:46.620 sex and we see Knight C friend. 07:46.620 --> 07:51.630 And this knight's now poised to actually help its fellow knight and get into key squares and the real 07:51.630 --> 07:56.940 key squares around the opponent's king here or in the vicinity, which are of great interest to white 07:56.970 --> 07:59.820 to try and make that king still in the center. 07:59.820 --> 08:02.310 The position looks absolutely overwhelming. 08:02.310 --> 08:07.350 Even though White's a bishop down, it looks like an overwhelming position. 08:07.350 --> 08:12.360 We see Bishop see five and now 95 is played. 08:12.600 --> 08:15.000 Yeah, this looks absolutely fantastic. 08:15.510 --> 08:22.980 If the four bishop be six this this also could be played and here Knight takes G seven shank This is 08:22.980 --> 08:30.420 very very dangerous Bishop these six Jack G five this is still this is like a really dangerous, incredibly 08:30.420 --> 08:36.060 dangerous position for, you know, the king Safety has been shot here. 08:36.990 --> 08:47.910 It's actually a mate a force to mate here if f6 G takes f6 king of some G seven king six for Czech king 08:47.940 --> 08:52.680 takes d6 e5 Czech king C 796 is checkmate. 08:52.680 --> 08:56.070 Yeah, there's force mates around. 08:56.100 --> 08:57.360 This is absolutely amazing. 08:57.360 --> 09:05.160 But default, this is like a variation which it just shows the enormity of White's position that there 09:05.160 --> 09:06.240 are variations like this. 09:06.240 --> 09:12.060 And if Bishop takes D4 even more great basically, which is not helping Black's position, greed does 09:12.060 --> 09:14.250 not help the whole position here. 09:14.280 --> 09:16.740 97 Czech 1984. 09:16.770 --> 09:17.940 This is just crushing. 09:18.090 --> 09:25.680 So yeah, already D4 looks to be a super strong move, just maximising the position even further. 09:25.830 --> 09:28.560 But okay, 95 was played immediately. 09:28.560 --> 09:36.420 We have Queen size B2 and now this is the funny thing, this is absolutely unbelievable thing about 09:36.420 --> 09:42.360 this game, this next move, if you put it in light analysis, Bishop D6 on certain online sites like 09:42.510 --> 09:45.900 chess, it's like regarded as a blunder you actually need. 09:46.570 --> 09:47.350 The. 09:48.100 --> 09:54.020 Even Stockfish needs to have time to properly work out what the heck is going on. 09:54.040 --> 10:01.840 Here we have a very strange position where both Rucks can be taken potentially and all White's done 10:01.840 --> 10:07.840 is is kind of secure some escape squares to try and weave a mating that around the king. 10:07.930 --> 10:14.470 But yeah, it's another central move it's the bishop is now central White's just built and built on 10:14.470 --> 10:19.510 the position in an intuitive manner, trusting that the position will outweigh the material. 10:19.600 --> 10:24.130 And yeah, if you don't leave engines running, you know, they think that maybe Black's got resources 10:24.130 --> 10:25.570 here to draw or something. 10:25.600 --> 10:26.290 It's not the case. 10:26.320 --> 10:31.180 White definitely has a clear advantage, even with absolute best play. 10:31.180 --> 10:37.450 But there was a more accurate continuation with rookie one, which is a kind of delayed gratification 10:37.450 --> 10:38.470 of Bishop de Sex. 10:38.920 --> 10:46.720 If Bishop b7 Bishop de sex here is even stronger, it seems, in a way than the continuation of the 10:46.720 --> 10:48.280 game, which is absolutely brilliant. 10:48.280 --> 10:51.670 But this continuation with Bishop takes G1. 10:54.170 --> 11:01.340 Boy actually is in a situation a funny situation where queen are for. 11:03.130 --> 11:04.390 It's super strong. 11:05.710 --> 11:14.410 So like the bishops less left the scene here and it's trying to coordinate the queen and bishop to have 11:14.410 --> 11:18.340 multiple threats like 97 check their what is black do here? 11:18.340 --> 11:20.500 Bishop B six, Queen G five. 11:20.590 --> 11:26.800 And the positions reached this kind of threshold where it's difficult to defend the king. 11:26.800 --> 11:28.400 You know, 1967 check. 11:28.420 --> 11:30.010 Black would have to give up the queen. 11:30.010 --> 11:31.650 That's another key idea here. 11:31.660 --> 11:34.270 Just 1967, Black would have to give up the queen. 11:34.540 --> 11:38.560 And this was a 1966 check taking out the Rock. 11:38.560 --> 11:40.240 White's on top there. 11:40.360 --> 11:41.050 So it's funny. 11:41.050 --> 11:42.820 Rookie one is even stronger technically. 11:42.820 --> 11:46.120 But let's go into the game, which certain engines believe. 11:46.150 --> 11:51.910 Believe it or not, if you put it on a not enough analysis, the engine just can't evaluate. 11:51.910 --> 11:53.740 This is very difficult to evaluate this. 11:53.740 --> 11:57.190 We have Bishop takes G1, so this is a mistake. 11:57.190 --> 11:58.420 But Black was losing. 11:58.420 --> 12:08.170 In any case, if Queen takes a one check King E to saying no, take both my rocks here. 12:09.130 --> 12:12.220 If Queen B2, King D2. 12:13.320 --> 12:14.220 And it's still winning. 12:14.220 --> 12:18.030 For once, this position if Bishop takes JI won. 12:19.830 --> 12:24.990 There's a key move here which takes away a key defensive resource. 12:26.450 --> 12:27.890 Can you see what that is? 12:28.080 --> 12:29.290 400 points. 12:29.300 --> 12:30.470 What would you play in this position? 12:30.470 --> 12:32.060 So you've just lost both your rooks? 12:32.090 --> 12:32.950 No panic. 12:32.960 --> 12:36.010 The position looks really, really strong with these pieces. 12:36.030 --> 12:37.490 The king still in the center. 12:37.760 --> 12:40.040 We've got kind of a half woven mating there. 12:40.070 --> 12:41.120 What do we play here? 12:43.280 --> 12:43.850 Yeah, just. 12:43.850 --> 12:45.110 This is the quiet E-5. 12:45.140 --> 12:47.570 Just disconnect a little bit of disconnection. 12:47.570 --> 12:49.280 Disconnect the Queen from G seven. 12:49.760 --> 12:53.720 So the fret is actually now 90 6g7. 12:53.720 --> 12:56.750 Check King and Bishop C seventh mate. 12:57.500 --> 12:58.520 Let me put that on the board. 12:58.520 --> 13:03.830 You know, 85 knights as a token of 1967 Shank and Bishop C seven is checkmate. 13:05.060 --> 13:06.520 So what does Black do here? 13:06.530 --> 13:07.760 Bishop A6. 13:09.290 --> 13:21.590 Bishop before and blacks in huge trouble after this, if not to each sex, because that vocation of 13:21.740 --> 13:24.350 sex means that there's new resource de sex. 13:24.380 --> 13:29.450 If for example queen sex if I'm there's 90 sex check and. 13:30.850 --> 13:31.960 This is troublesome. 13:31.960 --> 13:38.980 You know, if KING if a queen size of seven and if King decides, we can take on seven at the very least 13:38.980 --> 13:41.830 to win the queen and the attack rages on. 13:42.370 --> 13:44.020 So let's imagine. 13:44.770 --> 13:49.660 Nice h six though, to defend f seven. 13:49.840 --> 13:53.680 This position is still really strong after four. 13:53.680 --> 13:53.920 Why? 13:53.960 --> 13:54.580 96. 13:54.580 --> 13:55.160 Check. 13:56.320 --> 13:57.250 And here. 13:58.670 --> 14:00.950 If King of eight. 14:03.550 --> 14:07.990 G five and White still got a big advantage in this situation. 14:08.200 --> 14:11.430 It's a fascinating set of scenarios. 14:11.440 --> 14:17.380 If we go back here just just to highlight some other stuff after this. 14:17.410 --> 14:26.590 E5 So I mentioned Bishop A6 F6 just to show 9/10 G seven check nine takes F6 and yeah, Black's running 14:26.590 --> 14:32.560 out of options for king safety you know Queen C1 shaking up to queenside C2. 14:32.590 --> 14:37.090 KING Geoffrey White's attack is still pretty vicious here. 14:37.120 --> 14:38.380 White's winning there. 14:39.790 --> 14:46.210 So if we go back to this bishop, A6 mainline bishop before, yeah, it's just problematic. 14:46.210 --> 14:49.270 This, this whole variation is in White's favor. 14:51.080 --> 14:52.430 If we go back. 14:54.300 --> 14:58.290 So this is one Queen E, one King E two. 14:58.320 --> 14:59.990 We mentioned Queen B2. 15:00.090 --> 15:02.250 If Queen cites G one just to show. 15:04.180 --> 15:06.610 Well, yeah, it's. 15:07.000 --> 15:07.570 It's. 15:09.040 --> 15:10.210 What would you play here? 15:10.210 --> 15:11.710 There's a false checkmate in this position. 15:11.710 --> 15:18.520 If this happens, our position is so dominant, we've really got to celebrate all its possibilities. 15:18.520 --> 15:21.730 We have nine tanks, g seven shank, and we've got a killer. 15:21.730 --> 15:22.210 Common square. 15:22.210 --> 15:23.470 Bishop C seven is checkmate. 15:23.500 --> 15:24.610 The Knights holding E eight. 15:24.610 --> 15:26.680 They're so wonderful stuff. 15:26.680 --> 15:26.890 Yeah. 15:26.890 --> 15:32.080 All of this stuff shows such dominating position does actually pay dividends. 15:32.080 --> 15:33.310 So back to the game. 15:33.310 --> 15:37.960 Bishop takes G1, made Wayne's task easier. 15:38.650 --> 15:43.540 We have E five here disconnecting the Queen from G7. 15:47.230 --> 15:49.400 Okay, So this is a. 15:50.680 --> 15:51.820 Very, very good stuff. 15:51.850 --> 15:53.710 E5 is good. 15:53.710 --> 16:03.460 And also, you know, Rookie won this position with 96 check nine takes F seven, Shaq, C, 96 Shaq. 16:03.760 --> 16:08.320 And the thing is, once F seven has been taken, the Queen's got access to that back row. 16:08.320 --> 16:15.550 So this variation shows some dangers there where black could be clobbered basically with rookie one 16:15.550 --> 16:19.870 but E5 and now that's what makes game special. 16:19.870 --> 16:22.360 The black is so greedy taking this off the rook. 16:22.600 --> 16:24.040 So both rooks taken. 16:24.040 --> 16:32.470 We have a really wonderful situation, the kind of effects, the side effects of materialism, these 16:32.470 --> 16:35.500 pieces kind of out of play away from the king. 16:35.710 --> 16:40.930 These pieces are asleep still in bed, spectator pieces. 16:41.560 --> 16:55.090 We have now huge fans of Black Steel with 96 destroyed if Bishop a6 97 Shank 9/10 A6 is troublesome 16:55.090 --> 16:55.810 for black. 16:57.410 --> 16:58.250 Say Quincy. 16:58.250 --> 16:59.930 Jeffrey Bishop. 16:59.960 --> 17:03.290 See, seven Shaq Black would have to give up the queen. 17:03.710 --> 17:04.430 There. 17:05.360 --> 17:14.870 If King size 96 is checkmate on the other way, plants could get mated on potentially the other way. 17:15.140 --> 17:16.880 Queen snakes have seven mating. 17:17.630 --> 17:21.980 So, yeah, that's that's very, very funny. 17:22.010 --> 17:23.570 Very, very problematic. 17:25.070 --> 17:28.730 If queen takes a two, might be four heads. 17:28.730 --> 17:30.680 The Queen and Nancy two. 17:31.130 --> 17:32.960 That's in Wayne's favor. 17:32.970 --> 17:36.830 One's going to potentially just take on eight soon. 17:36.830 --> 17:38.830 And the attack rolls on. 17:38.840 --> 17:42.050 If Bishop be six, Queen takes eight for sure. 17:42.080 --> 17:46.970 Queen C three night b4 protect c two and the attack rolls on her. 17:47.180 --> 17:50.060 Bishop c seven King D one. 17:50.210 --> 18:02.540 This position is also it's very strong after this situation with a free one is also in a winning position 18:02.540 --> 18:03.900 getting material back. 18:03.920 --> 18:06.230 Funny stuff, Really funny stuff. 18:06.230 --> 18:14.300 But anyway, Knights six was played and we have this iconic scene in in Blade Runner where we have this 18:14.300 --> 18:18.410 position and while it's absolutely winning here, there's a false checkmate. 18:18.440 --> 18:19.970 Can you spot what that is? 18:19.970 --> 18:25.790 If I give you 5 seconds to pause Video So for 500 points, can you spot the final checkmate sequence? 18:27.050 --> 18:32.210 It's not Also E5 just disconnects the Queen away from certain key squares, not even just G seven, 18:32.210 --> 18:33.770 but also F six actually. 18:34.250 --> 18:36.050 So that was a great disconnect. 18:36.050 --> 18:43.670 Move to further amplify the dominating look of the possession, how the pieces, you know, are so good, 18:43.670 --> 18:47.390 but without any key defensive resources on that diagonal as well from that queen. 18:47.390 --> 18:50.030 This bishop, of course, looks extremely irrelevant. 18:50.030 --> 18:55.280 But here yeah, there's a false checkmate with nine times G seven check. 18:55.310 --> 18:56.390 That's the first move. 18:56.390 --> 18:58.250 And can you see what the move is here? 19:01.920 --> 19:03.240 So once planned shut, mate. 19:03.240 --> 19:06.270 So check all checks, even the seemingly outrageous ones. 19:08.920 --> 19:09.670 Okay. 19:10.920 --> 19:11.790 Queen F six. 19:11.790 --> 19:12.600 CHANG Yeah. 19:12.990 --> 19:20.160 This gets access to E seven, so it takes away the defender from E seven 9/10 f sex and Bishop E seven 19:20.160 --> 19:25.950 is actually checkmate because this time it's guarding C seven and this night it's gone in E eight. 19:27.510 --> 19:29.250 So this is why it's the immortal game. 19:29.250 --> 19:33.480 It really actually, you know, is technically sound as well. 19:34.080 --> 19:34.380 Okay. 19:34.380 --> 19:40.080 There might be a more optimal move at a certain point, but you know it makes a huge impression and 19:40.080 --> 19:46.560 I was in for a shock on revisiting this game with more detailed analysis, but there's also a dedicated 19:46.560 --> 19:49.380 wiki page which has important analysis as well. 19:49.410 --> 19:54.090 Just in case you're getting the wrong impression from analysis, check the wiki page for the immortal 19:54.090 --> 19:54.660 game. 19:54.660 --> 19:56.190 There's analysis there. 19:56.220 --> 20:02.910 But yeah, this this, this whole game shows quite vividly. 20:02.910 --> 20:09.210 Not just the king in the sense of this whole notion of king safety versus material. 20:09.600 --> 20:16.560 Or you could say king safety verses a position which looks like really, really good, really dominating 20:16.560 --> 20:16.890 position. 20:16.900 --> 20:22.380 Sometimes we do need to, especially when we're playing people, we're playing people, not machines. 20:22.380 --> 20:29.070 So positions which really look great sometimes they aren't really great and it really needs huge effort 20:29.100 --> 20:32.760 on the part of engine to actually evaluate things properly. 20:33.150 --> 20:41.010 That huge, you know, that balance between material in king safety, all the strength, the good looking 20:41.010 --> 20:43.890 strength of position versus king safety. 20:43.890 --> 20:46.230 So the attacking plan needs to bear this in mind. 20:46.230 --> 20:52.110 You know, sometimes there's going to be intuitive sacrifices to get huge knights, for example, on 20:52.110 --> 20:58.200 day five or five and see what dividends they actually pay. 20:58.230 --> 21:00.600 What is the trend of the position after. 21:00.600 --> 21:03.920 So, yeah, this was an absolutely beautiful looking position. 21:03.930 --> 21:04.400 Okay. 21:04.440 --> 21:06.270 A bishop now on technicality. 21:06.270 --> 21:07.290 Look at the pieces. 21:07.290 --> 21:10.920 If they're going backwards, we're getting, you know, like a Morphy victim. 21:10.920 --> 21:13.920 Basically, when the pieces are in bed, I tend to think of it. 21:13.950 --> 21:16.230 Oh, this is a Morphy victim, Paul Morphy. 21:16.230 --> 21:21.480 But no, this is actually Adolf Anson, again, one of the great attacking players of that time. 21:22.740 --> 21:28.860 And he's just wrapping himself around the king systematically and, you know, using a key disconnection 21:29.760 --> 21:30.630 resource. 21:31.200 --> 21:34.290 But yeah, this is absolutely, you know, a winning position. 21:34.290 --> 21:38.640 It's great to think that you can play like this in such a romantic fashion. 21:38.730 --> 21:47.070 And, you know, hundreds of years later, you know, it's proven by modern technology that actually 21:47.070 --> 21:48.480 there is something about this. 21:48.510 --> 21:49.800 It's actually rather sound. 21:49.800 --> 21:55.620 So it does kind of create a liberation effect for me, you know, material. 21:56.400 --> 21:59.370 Yeah, is is an obsession, but it's not the only element. 21:59.370 --> 22:03.600 How how good looking is the strength of your or the strength of your pieces. 22:03.600 --> 22:06.300 Are they much more developed than the opponent, the whole position as a whole? 22:06.330 --> 22:08.700 How does that link with King safety? 22:09.060 --> 22:11.700 So this balance get it right, try and get it right. 22:11.790 --> 22:17.760 The attacking players, You know, when we see examples like this, these are mortal games. 22:17.760 --> 22:25.320 They are really inspirational, in my view, for attacking chess and sacrificing and combinations. 22:25.530 --> 22:26.340 Okay. 22:27.060 --> 22:27.780 Thanks so much.
