WEBVTT 00:01.290 --> 00:05.190 Hi there in this letter, I want to introduce you to the London system. 00:05.730 --> 00:08.610 Now you can check out my dates, of course, in London system. 00:08.640 --> 00:10.490 It's a great repertoire in its own right. 00:11.070 --> 00:17.730 So if you want to know a system with whites, which avoids too much opening theory, which you might 00:17.730 --> 00:24.450 need to memorize at the expense of spending time on other essential parts of your game, like middle 00:24.450 --> 00:27.840 game and name, you might want to use a system. 00:28.500 --> 00:35.250 There is some good logic in using a system just to get you over the first few moves castling safely 00:35.760 --> 00:37.270 with a reasonable position to playing. 00:38.130 --> 00:42.480 So the London system starts with day four of the night and things. 00:42.870 --> 00:45.390 The trends you move now is before. 00:46.380 --> 00:47.500 This is a great move. 00:47.520 --> 00:51.800 We see D5 Efrain six 92. 00:51.810 --> 00:58.770 Now, the example game I'm showing you here from this position is Gasa Camp's game against Samuel Shankland. 00:59.070 --> 01:01.350 It also demonstrates an interesting trap. 01:01.350 --> 01:02.670 Later, quite a deep trap. 01:03.240 --> 01:06.690 So what is going on with this London system? 01:07.050 --> 01:10.500 Well, it sets up this solid pawn triangle. 01:10.500 --> 01:11.820 That's a key characteristic. 01:12.120 --> 01:14.580 And the bishop is outside of the pawn chain. 01:14.580 --> 01:17.550 It's not stuck at home on C one. 01:18.570 --> 01:21.660 We see Ninety-Six in this particular game like Geffray. 01:21.660 --> 01:25.440 So why is reinforcing control over a key central square? 01:26.310 --> 01:32.490 Bishop desex Bishop Geoffrey why it doesn't mind double --'s on this occasion, there is an upside 01:32.490 --> 01:35.160 Black didn't take on Jeoffrey Black household. 01:36.000 --> 01:38.490 If it does take on Jeoffrey a key thing. 01:38.730 --> 01:44.520 Most London systems are what most London system players are aware of is that you get good play of the 01:44.820 --> 01:46.500 takes even though the --'s doubled. 01:47.040 --> 01:48.300 The upside is the rook's. 01:48.510 --> 01:51.240 That's the general thing about chess trade offs. 01:51.690 --> 01:57.660 Structurally, sometimes you can have double pawns, but you could have an active rook as an upside. 01:58.050 --> 01:59.970 So plac didn't even want to do that. 02:00.780 --> 02:03.000 We see black playing just castling. 02:03.180 --> 02:07.620 Yeah, Bishop defraying, we see Queene seven and I-95. 02:08.970 --> 02:10.830 We see here these seven. 02:12.630 --> 02:17.610 If Knight takes E5 then details. 02:17.610 --> 02:20.520 If I have actually your -- bishop at night. 02:21.300 --> 02:22.620 So you're winning material there. 02:24.030 --> 02:25.140 So 97 02:27.690 --> 02:36.710 we have now maintains the seven bishop takes the seven and this looks a little bit harmless. 02:36.710 --> 02:38.490 Is that why it's just exchanging pieces? 02:39.060 --> 02:45.210 But there's a fantastic idea here of the detainees 2095. 02:46.590 --> 02:53.430 There's an absolutely staggering, immense idea which made this particular game example extremely famous, 02:53.430 --> 02:55.170 actually began to Chomsky. 02:55.170 --> 03:00.660 So here's one of the pioneers of the land system, and this is one of his most famous wins with hands. 03:01.320 --> 03:08.610 Can you guess what will replace her if I give you five seconds pause where it's actually rather subtle. 03:08.610 --> 03:11.190 It's it's a very, very advanced tactical combination. 03:12.450 --> 03:18.060 So I think I'm just going to show you now as Bishop six, eight, seven check, it does bring the count 03:18.640 --> 03:19.740 coordinates five check. 03:19.950 --> 03:26.100 The important thing here is we've got an x ray against the queen and actually we can use the pins pawn 03:26.100 --> 03:28.020 now with Ninety-four. 03:28.860 --> 03:31.830 So that pawn is pinned because otherwise we'll just take the queen. 03:32.160 --> 03:33.930 So the night is assisting the queen. 03:33.930 --> 03:36.600 Now, sometimes we see Quincy for 03:39.390 --> 03:44.730 if she thinks that might just take some C5 and takes on D7 with advantage. 03:44.730 --> 03:46.500 So this will be a nice advantage for whites. 03:47.640 --> 03:51.150 So Queen seafoam, we see ninety five. 03:52.170 --> 03:56.160 So White is now threatening checkmate with the White Queen. 03:57.030 --> 03:59.920 So cauterising on eight seven Urbino escape sequence. 03:59.940 --> 04:01.230 Just to put that on the board for you. 04:01.650 --> 04:08.760 If Rook ACA Queen 87 is checkmate so much that maybe you should be well aware, well aware of when the 04:08.760 --> 04:10.050 opponent's castle. 04:10.050 --> 04:15.600 Kingside, if you have a night in queen like that, that's a winning method quite often when there's 04:15.600 --> 04:16.400 no defense of night. 04:16.420 --> 04:25.850 Lefsetz but anyway, we see the rook giving the King some air effort to escape to Queen takes f7 check. 04:26.700 --> 04:35.790 Check King James and then Rudy one we see five Queen f7 check King James and our efore. 04:36.900 --> 04:39.840 There are various ideas afoot here for White. 04:40.710 --> 04:43.740 I don't want to go into too much of the complex details. 04:44.160 --> 04:45.150 Let's just see the game. 04:45.240 --> 04:51.120 Ninety seven was a desperate move though, giving back pace. 04:51.960 --> 04:57.030 The thing is, what can Black actually do here if bishop ice queen if is checkmate. 04:59.190 --> 04:59.830 If I. 04:59.920 --> 05:08.170 Five, six is very dangerous for have might and hair, Brooke, the five and then check and I'm rotates 05:08.180 --> 05:14.590 the seven is strong, for example, this situation, because that was also hitting the queen. 05:14.950 --> 05:16.950 It's just winning loads of material wise. 05:18.040 --> 05:19.730 So we'll look at that again here. 05:19.870 --> 05:22.740 This is a nasty tactic that we just saw. 05:22.750 --> 05:25.270 Rook takes these look at the effect on the whole position. 05:25.900 --> 05:29.430 We're actually hitting the queen and now this is Jack. 05:29.440 --> 05:32.050 So, yeah, all these lines are very bad. 05:32.590 --> 05:34.260 So this is a desperate try. 05:35.440 --> 05:40.180 Queen Elizabeth, be five black is frightening to my only two. 05:40.540 --> 05:53.650 That's Parit Queen takes her to Queen f7 Jack will be one queen takes me to Jack King James check king 05:53.700 --> 05:57.580 Afghans check King seven Queen 67. 05:57.580 --> 05:59.440 Check King MI6. 05:59.440 --> 06:00.760 But now rotate 85. 06:00.760 --> 06:05.740 Check out the King's Essex Queen Essex Check and the game ended here. 06:07.000 --> 06:17.970 If the game continues with King C7 then ninety six Jack and taking on the eight winning Momotaro 1968 06:17.980 --> 06:19.810 is track so. 06:21.660 --> 06:28.290 The London system, as shown in this game, is pretty dangerous if the game continues, if the bishops 06:28.290 --> 06:34.740 C6 six just councils once got a big advantage, an extra rook up. 06:35.910 --> 06:36.450 So. 06:38.580 --> 06:46.260 The London system was kind of made famous by gas, escaped with winds like this especially so essentially 06:46.890 --> 06:51.900 coming back to the opening idea, it's a bishop outside of the -- chain. 06:53.430 --> 06:58.490 It saves you spending months looking at technical opening very in one A4. 06:58.500 --> 07:02.600 So it's even just a day for opening, not only for opening. 07:03.480 --> 07:07.350 It's a system which means that there's less very to know about. 07:07.350 --> 07:10.590 You can play it largely independent of what the opponent does. 07:10.900 --> 07:16.890 But nevertheless, if you want more details about how to handle different things that black and you, 07:16.890 --> 07:21.000 you know, check out my London system course for more detail on that. 07:22.290 --> 07:32.460 So it's a great standby opening and should get you lots of points, especially if you build up your 07:32.470 --> 07:37.680 middle game in and game relative to your opponents in your early stages of learning chess. 07:38.010 --> 07:40.440 Having these systems is not a bad thing. 07:40.740 --> 07:44.540 Bobby Fischer had a system, the American chess legend. 07:44.580 --> 07:51.300 He played the Kings in an attack which will introduce actually shortly. 07:51.330 --> 07:57.990 OK, so but this is the London system, just a very, very important game example. 07:58.500 --> 08:02.130 But the basic principle is the bishop outside of the pawn chain. 08:04.500 --> 08:08.400 And there are certain dynamic, very interesting things that can happen. 08:09.450 --> 08:12.660 As we saw, doubling pawns is not a big deal when you activate Rook's. 08:13.110 --> 08:18.640 And here we saw very, very dynamic attack opportunity that was used by Gostkowski. 08:18.910 --> 08:21.000 OK, that's a much.
