WEBVTT 00:00.810 --> 00:01.620 Hi there. 00:02.010 --> 00:07.140 In this lecture, we see the first official world chess champion Wilhelm Steinitz playing against Augustus 00:07.150 --> 00:09.300 Mongolian in 1862. 00:09.300 --> 00:15.080 A highly celebrated casual game We have E4 and we see the modern defence G6. 00:15.120 --> 00:18.660 So this does incur certain downsides. 00:18.660 --> 00:20.040 Don't square weaknesses. 00:20.400 --> 00:24.960 The film cuts out in hyper modern tradition, exerts pressure on white center. 00:25.410 --> 00:29.610 It's fine, it's blunt set with C frame and now we get a double thing. 00:29.610 --> 00:42.090 Kato B6 so very very hyper modern from Mongolian Bishop E3 Bishop b7 92 protecting e4 pawn we have d 00:42.090 --> 00:49.440 sex knight Geoffrey and now e5 Black's already. 00:49.440 --> 00:52.440 You know technically this isn't so clever, this opening. 00:52.440 --> 01:01.830 It looks kind of fun and maybe it can go into a hippo if black plays a bottomless defense if a6 e6 h6 01:01.830 --> 01:05.790 and the knights arrange themselves, we'd have a hippopotamus set up. 01:05.790 --> 01:08.040 But Black commenced at E5. 01:08.490 --> 01:10.140 This isn't so good. 01:10.170 --> 01:14.880 Waiting around a little bit with 97 might have been more prudent, more safer. 01:14.910 --> 01:21.480 Bishop D3 You know this position gives one a small edge though, but E5 makes things worse. 01:21.480 --> 01:21.840 For Black. 01:21.840 --> 01:29.880 We have D tanks, e5 D tanks, E5 and now Bishop C4 97 and now Queen E two. 01:29.970 --> 01:36.780 Y has the option now of Castle than queenside Black Castles into an attack here. 01:36.780 --> 01:38.790 The thing is, the knight's on E seven. 01:38.790 --> 01:39.960 It's not on f6. 01:39.960 --> 01:46.230 This makes it much more lucrative for a classic undermining of this structure to open up the rook on 01:46.230 --> 01:49.770 the h file, which creates very nice tactical possibilities. 01:50.160 --> 01:53.520 Black had to consider something like 98. 01:54.510 --> 01:56.850 So for example h4 try and keep things closed. 01:56.850 --> 02:00.090 The H6 and this position try and keep things closed. 02:00.090 --> 02:08.820 But even here, White does have an advantage or another possibility instead of H six Knight D six going 02:08.820 --> 02:09.840 for this bishop. 02:10.530 --> 02:19.080 And this situation though is interesting and black might actually get a position where they can try 02:19.080 --> 02:21.930 and get the Queen's off this position. 02:22.560 --> 02:29.850 But even here, even with this resourcefulness from black white, it's still better here in this situation. 02:29.850 --> 02:38.790 H takes we can see that rooks kind of valuable to open up Knight G5 and it has good prospects here. 02:39.390 --> 02:44.460 So anyway, but what is played makes things very, very easy for white. 02:44.490 --> 02:46.410 It's a very, very standard looking attack. 02:46.410 --> 02:54.210 Age four we have 97 if h six here, this is quite interesting to consider. 02:56.010 --> 02:58.290 White could console queenside still. 02:58.410 --> 03:02.010 And what would you play here to try and attack the defend Catto structure. 03:02.010 --> 03:09.840 There is a very nice attacking move available here based on H four and it's vacation actually of H two. 03:10.140 --> 03:12.240 So what would you play here for ten points. 03:14.100 --> 03:14.370 Yeah. 03:14.370 --> 03:20.490 We can actually use that square with Knight H two to go in with Knight G4 This would be a very good 03:20.490 --> 03:21.630 way of playing things. 03:21.630 --> 03:27.270 Knight G4 If the king protects, we can actually play Knight free. 03:27.660 --> 03:31.860 So now the Queen contacts of G5 check and we're going to be winning the Queen. 03:32.070 --> 03:33.060 That's going to be good for white. 03:33.060 --> 03:41.460 So let's imagine here Bishop A6 Knight G five Check with the king on the H file is super dangerous here. 03:41.820 --> 03:48.390 So for example, Knight takes F seven, rook takes up seven, Bishop takes up seven, check king tanks, 03:48.390 --> 03:54.960 the king's exposed and actually we can then take on H six and the attack just carries on. 03:55.830 --> 03:59.820 For example, this situation, even the endgame here is just better. 03:59.820 --> 04:04.320 For one, this endgame scenario, even if we reach this scenario, it's just better for white. 04:04.320 --> 04:07.440 So that's a fictional scenario with H six. 04:08.610 --> 04:10.050 If we just look at that again for the moment. 04:10.050 --> 04:12.750 So we're saying Knight H two would be a good recipe. 04:14.890 --> 04:15.430 Yeah. 04:15.580 --> 04:20.860 And just later on in this analysis, let me just show you something else here. 04:20.890 --> 04:27.010 So this is a demolition job, but say King Gates, the king had gone that way. 04:27.340 --> 04:28.360 96, 86. 04:28.360 --> 04:28.930 Check again. 04:28.930 --> 04:30.460 We can just open things up. 04:30.820 --> 04:32.710 And this is a very strong attack. 04:32.740 --> 04:34.090 This situation. 04:35.700 --> 04:41.820 Trying to avoid these scenarios where the H file is really good here. 04:41.880 --> 04:44.130 There's a beautiful tactic in this variation. 04:44.250 --> 04:46.140 Can you see what would play here? 04:48.700 --> 04:49.720 At some points. 04:49.840 --> 04:51.070 Check all checks. 04:52.630 --> 04:52.860 Yeah. 04:52.930 --> 04:54.360 Queen G seven Shank. 04:54.370 --> 04:56.380 And this is just absolutely winning as a rookie. 04:56.410 --> 05:01.240 Jake Shank then crashing through and Mason shortly after. 05:01.480 --> 05:03.550 So yes it's interesting situation. 05:03.550 --> 05:06.670 So eight six seems to be out of the question. 05:06.790 --> 05:09.100 You might ask what about h five here? 05:09.130 --> 05:13.390 There is a way of proceeding here which might actually apply to some of your games where you think, 05:13.390 --> 05:15.510 well, I can never get these attacks going. 05:15.520 --> 05:16.530 They've just blocked me. 05:16.540 --> 05:21.730 Now, there's something I love doing here and I win lots of games with this kind of mechanism. 05:21.730 --> 05:29.590 I love trying to peel open the king with a pawn sack like G4 generally to consider this here. 05:30.610 --> 05:33.190 If h takes G4, we have nice h two. 05:33.460 --> 05:37.000 And what is that black player with this pawn pins? 05:37.000 --> 05:39.850 There's no easy F five because that's an illegal move. 05:39.880 --> 05:46.600 If g free we can play like G4 and this position is very, very strong for white. 05:46.630 --> 05:48.040 The attack rages on. 05:48.340 --> 05:48.820 Yeah. 05:48.820 --> 05:54.790 For example, this situation Bishop thinks Queen F6 is diabolical. 05:55.300 --> 05:57.040 You know, we're just crashing through. 05:57.040 --> 06:05.230 So yes, in the case of h5g4, this is something to consider in another just situations in your own 06:05.230 --> 06:05.800 games. 06:05.800 --> 06:10.690 Black could try and be resourceful here with B5 to get the bishop off this diagonal. 06:10.720 --> 06:16.780 Let's say this happens like gg4, F five, let's say this happens. 06:17.320 --> 06:19.960 Yeah, we've got enough pressure on the king. 06:19.960 --> 06:26.530 We can afford a piece sack if the bishop goes back now with the Czech Queen six G4 This is just a very 06:26.530 --> 06:27.700 strong attack. 06:27.700 --> 06:32.230 We've got enough attacking pieces whilst these guys are just asleep here. 06:32.620 --> 06:35.890 So this situation with Bishop thanks. 06:35.900 --> 06:36.280 Have seven. 06:36.280 --> 06:40.780 We're crashing through here and we've got a raging attack essentially. 06:41.140 --> 06:46.210 So this is very much an advantage for white crashing through like this. 06:47.590 --> 06:53.020 So anyway, yeah, it does seem as though technically, you know, black's in huge trouble here. 06:53.020 --> 06:57.370 We have Knight D seven just not doing anything about H five. 06:57.760 --> 07:03.430 So we're getting a classic semi fa very dangerous semi fa near to the opponent's king and an opposite 07:03.430 --> 07:04.990 side castling recipe. 07:05.920 --> 07:16.030 So 1986 opposite side castling c59g5 and now a six is played. 07:16.270 --> 07:22.450 Yeah, this is a very, very bad position if B5 trying to get some council like this Queen C seven bishop 07:22.450 --> 07:28.630 just goes back to that amazing place nine takes F seven is actually justifiable here because we're getting 07:28.630 --> 07:29.830 huge pressure on the king. 07:29.830 --> 07:33.280 We're opening up the king, big Queen H six. 07:34.320 --> 07:38.440 So so for this position, we're going to just work with G free very soon. 07:38.440 --> 07:41.650 So that stabilizes the F3 and stabilizing E4. 07:41.650 --> 07:48.490 About G three here is just opening up the king as an example with interest. 07:48.490 --> 07:51.640 So this is not going to be ending well for black. 07:51.730 --> 07:56.620 This is not I wrote the seven check taking out B seven. 07:56.950 --> 08:00.280 Yeah, it's just a pulverizing scenario. 08:01.630 --> 08:02.410 So. 08:02.410 --> 08:02.860 Okay. 08:02.860 --> 08:04.470 So yeah, the resource will be fine. 08:04.500 --> 08:06.220 Doesn't really do anything now. 08:06.220 --> 08:12.460 So A6 and now nice combination will play from Steinitz. 08:12.460 --> 08:13.750 So what would you play here for? 08:13.750 --> 08:14.710 100 points. 08:20.520 --> 08:21.240 Okay. 08:21.870 --> 08:23.690 Nice sacrifice night. 08:23.690 --> 08:24.410 Six, eight, seven. 08:24.420 --> 08:29.490 It creates that weakness of the last wave of h five, letting the queen come to a very aggressive square. 08:29.670 --> 08:33.150 But rotates, takes h seven is played here. 08:34.800 --> 08:38.280 Queen H five is also very, very strong, as you might imagine. 08:38.280 --> 08:41.700 So because it hits H seven and it hence g six. 08:42.300 --> 08:43.230 So six. 08:43.230 --> 08:44.220 Queen size G six. 08:44.220 --> 08:45.600 This is very, very good. 08:45.600 --> 08:48.870 Bishop D five trying to be resourceful. 08:51.090 --> 08:53.730 But you know why? 08:53.760 --> 09:01.470 Because just for example, Bishop size play this Queen 67 and is a piece up at the very least. 09:03.210 --> 09:05.010 So yeah. 09:05.010 --> 09:06.840 So Queen H five is absolutely winning. 09:06.840 --> 09:11.700 But also Rook takes age seven as played, creates a neat combination. 09:11.700 --> 09:13.890 So King says H seven, Queen H five. 09:13.890 --> 09:16.920 Shaq King James Rook H one. 09:16.920 --> 09:18.630 So the threat now is Queen H seven. 09:18.630 --> 09:19.440 Checkmate. 09:21.270 --> 09:23.490 So rookie eight Queen Thanks. 09:23.490 --> 09:27.180 G six So yes. 09:27.180 --> 09:28.320 F seven is a problem. 09:28.320 --> 09:31.920 Queen F six And now a really neat idea is played. 09:33.510 --> 09:35.160 Which isn't strictly needed. 09:35.160 --> 09:37.860 But can you see what plays here for ten points? 09:38.190 --> 09:41.220 We have a combination here to win the Queen. 09:41.310 --> 09:42.850 Actually, that's a clue. 09:42.870 --> 09:44.190 So why not play? 09:44.190 --> 09:45.060 What would you play? 09:48.660 --> 09:50.970 So we don't want the king necessarily escaping. 09:51.420 --> 09:53.820 Eight We played Bishop takes F seven shank. 09:54.330 --> 09:55.890 This is a great way of playing it. 09:57.890 --> 09:59.060 Before we get into that. 09:59.060 --> 10:01.010 Queen age seven is also dangerous. 10:01.010 --> 10:02.810 For the record, we're broke free. 10:05.060 --> 10:13.820 So this situation looking at F seven if rookie six recovery, this is kind of crushing but what does 10:13.840 --> 10:14.750 plant do here? 10:16.640 --> 10:16.880 Rook. 10:16.880 --> 10:17.570 Dang. 10:18.660 --> 10:19.750 Just letting the queen go. 10:20.540 --> 10:21.760 It's still much better for white. 10:21.770 --> 10:23.570 So that was a way of playing as well. 10:23.570 --> 10:25.100 Just Queen H seven check. 10:25.100 --> 10:26.030 But in the game. 10:26.030 --> 10:26.240 Yeah. 10:26.270 --> 10:29.870 Bishop takes f7 check was played. 10:33.030 --> 10:34.410 So very interesting situation. 10:34.440 --> 10:35.940 Bishop takes up seven. 10:35.940 --> 10:37.080 Queen, Banks have seven. 10:37.080 --> 10:40.830 So the king is a bad protector in general of any peace. 10:40.980 --> 10:42.670 So why is it a bad protector here? 10:42.690 --> 10:43.620 What is at play here? 10:43.620 --> 10:44.910 Which is a winning move? 10:47.640 --> 10:48.570 At ten points. 10:51.670 --> 10:53.330 You know, rook h h ach. 10:53.330 --> 10:55.790 Just deflecting the king away from f7. 10:57.410 --> 10:58.360 End of game. 10:58.370 --> 11:02.090 If the game continues, there's not too much point here. 11:02.450 --> 11:06.590 Although Black does seem to have a lot of material, we could play Queen G6 as an example. 11:06.950 --> 11:08.330 Kick the bishop away. 11:08.440 --> 11:10.820 1903 This is just a fictional example. 11:10.850 --> 11:17.090 Of course, Queen f7 and E5 is going to drop at some point. 11:17.090 --> 11:18.370 You can see the pressure on E5. 11:18.380 --> 11:24.990 We can cash out by looking at E5 here, and this is going to be easy to convert here. 11:25.010 --> 11:27.140 We've got a lot of pawns extra. 11:27.140 --> 11:28.670 We've got three pawns extra. 11:29.030 --> 11:33.080 So anyway, what do we get from this classic iconic game? 11:33.110 --> 11:36.260 Okay, first of all, it is really, really beautiful, the combinations. 11:36.260 --> 11:40.310 But we also want to know from a learning perspective of attacking a thinker. 11:40.310 --> 11:43.580 So the technicalities of defense. 11:44.030 --> 11:44.720 You know what? 11:44.720 --> 11:47.900 If so, we've looked at a few what ifs in recap here. 11:47.930 --> 11:53.960 What if h6 What if h five We have peeling operations available. 11:55.330 --> 11:56.920 And so it's quite interesting. 11:57.160 --> 11:58.720 Like H five, G four. 11:59.200 --> 12:01.420 So, yes, don't be afraid to peel open. 12:01.420 --> 12:05.050 Sometimes it's really the right thing to do to peel open the possession. 12:05.050 --> 12:09.010 So that is a very strong move here, as mentioned in the variations. 12:09.010 --> 12:15.780 But H six yes, we mentioned variations there with H six and with the idea of using the H two square. 12:15.790 --> 12:22.840 So yes, the thing canto is a bit of a liability, especially on opposite side casting games where horrible 12:22.840 --> 12:24.190 things can happen here. 12:24.220 --> 12:32.230 So yes, but Black made things very kind of clear cut, just allowing the semi-open h file and the tactics 12:32.230 --> 12:35.320 are just absolutely just waiting to be played here. 12:35.830 --> 12:39.670 So nine times eight seven is just a crushing blow, really. 12:39.850 --> 12:42.160 Okay, so I hope you enjoyed this game example. 12:43.300 --> 12:50.050 And we can see the liabilities of when there's a thin cathode construction and also adding in the mix 12:50.050 --> 12:53.110 here opposite side castling makes it super fun to attack. 12:53.110 --> 12:58.450 I think Ito with the whole hack attack OC had so much.
