WEBVTT 00:01.020 --> 00:01.620 Hi there. 00:01.890 --> 00:07.200 In this lecture, let's look at the so-called mainline historically fruitiness of the past. 00:07.500 --> 00:14.400 This is really deep opening territory, thoroughly analyzed, so much so that a lot of grandmothers 00:14.400 --> 00:22.890 are choosing different first moves, the English opening or move one has greatly increased in popularity 00:23.340 --> 00:24.380 in recent years. 00:24.390 --> 00:29.950 Grandmothers are interested in winning and not necessarily following the most beaten path. 00:30.150 --> 00:33.690 There's a difference between popular paths and trying to win chess game. 00:33.690 --> 00:36.930 So quite often the English opening has been used. 00:37.680 --> 00:39.690 DeFore has risen in popularity. 00:39.690 --> 00:43.170 So are the first moves like DIPHONE and CIFOR. 00:43.650 --> 00:49.740 So E4, though, is the most forensically analyzed opening and within that the order pairs is one of 00:49.770 --> 00:53.030 the most forensically analyzed variations. 00:53.790 --> 01:01.650 So we see in the main line of the ASX Bishop A4 might have six white castles. 01:04.140 --> 01:10.950 We see he's seven now, why it shouldn't take because it's no good here, but after he won, why is 01:10.950 --> 01:21.390 friends, think tank and black plays quite often B5 should be free and now desex six seefried black 01:21.390 --> 01:22.050 castles. 01:22.050 --> 01:23.960 And here we are at moved nine. 01:24.300 --> 01:28.670 And it's important to be specific with move numbers. 01:28.740 --> 01:30.210 Look at this index above. 01:30.210 --> 01:31.260 So move nine. 01:31.260 --> 01:38.280 There's a number of names, variations, the Powell neck variation, the three, the Yates and Bacolod 01:38.330 --> 01:46.770 Zubov racial defo or Bogalusa Bell rising before the sugaring version age and then black plays A5. 01:47.460 --> 01:54.210 Yeah, the H3 might be Ade's version, which is a favorite of Mangahas Coalson this night. 01:54.210 --> 02:00.810 Retrade the Broyer variation is a real favorite with our current world chess champion, the Zaitsev 02:00.810 --> 02:02.340 variation B seven. 02:03.510 --> 02:09.660 The competition named after Anatoly Karpov D7, a fantastic world champion. 02:10.080 --> 02:11.910 I gave Garry Kasparov a hard time. 02:12.810 --> 02:16.950 The Comal variation Bishop ESX, the SMEs. 02:17.520 --> 02:21.120 They got Vasily Smith of another great world chess champion six. 02:23.360 --> 02:26.610 And there's also Queen D7 attributed to Spacelab as well. 02:27.440 --> 02:33.770 So, yeah, those are very, very important mainline variations to know about. 02:35.360 --> 02:38.360 So it all kicks off her move noin. 02:38.750 --> 02:41.250 Now let's rewind back. 02:41.960 --> 02:50.090 So aside from that main variation, if we go back and rewind to move free, Black does have some unusual 02:50.090 --> 02:53.360 alternatives other than assets which I love playing. 02:53.600 --> 02:56.990 My favorite person is G six, which is the spirit of the fence. 02:56.990 --> 02:58.000 So many of these. 02:58.140 --> 03:04.670 So again, I don't think capturing my bishop and then 97 and sort of Kingside Avalanche later, I like 03:05.090 --> 03:08.090 doing that, but that's going all the hair. 03:08.270 --> 03:14.160 The Cosio defense is also sometimes used by grandmasters as a surprise weapon. 03:14.180 --> 03:16.210 So this is my favorite personally. 03:16.820 --> 03:23.480 The Birds defense is a bit of a trap, more of a trappy line. 03:25.160 --> 03:27.080 Yeah, I mean white. 03:28.480 --> 03:31.190 Can just take with an advantage. 03:31.780 --> 03:33.580 There's ways of getting a clear advantage. 03:33.700 --> 03:36.610 I don't really recommend the defense too much. 03:37.900 --> 03:41.350 It reminds me of it's not quite the Spanish game. 03:41.950 --> 03:47.830 And the Italian game seems to have you know, there is Ninety-four here, which is a trap, which is 03:47.980 --> 03:51.010 well worth knowing about where one gets mated. 03:51.010 --> 03:53.710 So in the trap section, you might to review that. 03:54.280 --> 03:58.240 But here five, it kind of reminds me it's not quite the trap line. 03:59.050 --> 04:01.020 It is a legitimate defense. 04:01.030 --> 04:08.010 But the fence named after Henry Bardes, so we have also the Stinnett's defense here. 04:08.350 --> 04:15.370 It seems like a little bit of a passive move and it can be deferred until later, delayed, deferred 04:15.550 --> 04:17.470 until later that its defense. 04:18.400 --> 04:21.340 But it is kind of like the position can be quite solid. 04:22.150 --> 04:26.310 We have also very aggressive Schliemann defense at five. 04:26.830 --> 04:32.530 We have the classical defense Bishop C5 and we have the dreaded Berlind defense. 04:32.530 --> 04:39.970 And this is definitely not this might be lost, but it's definitely not least because Vladimir Kramnik 04:39.970 --> 04:46.990 has made this a formidable weapon of choice and yet another reason why modern grandmasters are not playing 04:46.990 --> 04:47.970 onea for as much. 04:48.310 --> 04:55.450 It's got a really, really solid, reliable reputation, the Berlin defense, and has been used on recent 04:55.750 --> 04:58.420 world championship matches. 04:58.990 --> 05:08.620 So Black really is potentially threatening to take on a for here as an example of the dreaded Berlin 05:09.310 --> 05:09.930 defense. 05:09.940 --> 05:16.520 If White Castles Black takes this pawn now say, you know, to make moves like rookie one day for, 05:16.520 --> 05:22.060 say, DeFore and the Queens are kind of answering each other quite quickly here. 05:22.060 --> 05:32.050 And actually, there's a situation now where black attacks that night on B5 encouraging this and then 05:32.050 --> 05:34.750 encouraging this and encouraging white to take the queens off. 05:35.290 --> 05:41.620 But the situation here, black does have that bishop power, even though black has double pawns here, 05:42.280 --> 05:47.410 this is fought to be fairly solid, even though blacks also lost casting rights because the queens are 05:47.410 --> 05:48.160 off the boards. 05:48.160 --> 05:50.800 You know, the verdict on this position is far from clear. 05:51.220 --> 05:58.630 A lot of grandmasters are simply avoiding playing one E4 because of this very, very solid Berlinda 05:58.630 --> 05:59.070 fans. 05:59.080 --> 06:02.140 So, yes, it's kind of the bane, the grandmaster level. 06:02.410 --> 06:06.130 So it's definitely a good weapon of choice with the black pieces as well. 06:06.130 --> 06:12.820 If you want something super solid and bypassing a lot of the royal of the pads, very believe it or 06:12.820 --> 06:14.120 not, just don't move. 06:14.120 --> 06:15.520 Free the ball in the fence. 06:15.520 --> 06:17.320 Just just bringing out the other night. 06:17.770 --> 06:21.970 I know it's it's a lot of big territory to know. 06:23.080 --> 06:28.630 So just to recap, if White Castles 964, you need to be prepared for rookie one or D for. 06:28.630 --> 06:34.570 So defo you had that bishop encourage why to kind of swamp off the Queen's and it's actually a fine 06:34.570 --> 06:35.430 position for black. 06:35.710 --> 06:37.150 Check out the slam games there. 06:37.420 --> 06:39.250 OK, it's very theoretical and trendy. 06:39.880 --> 06:47.350 So OK, I hope this is just a very, very quick tour of some of the major name variations through the 06:47.350 --> 06:53.620 ages in the world powers, one of the most theoretically analyzed openings in chess. 06:54.070 --> 07:00.070 And it's nice, I think, culturally to know at least some of the names and the world champions and 07:00.400 --> 07:06.850 other great players that have given contributions to the world powers over the last few hundred years. 07:07.300 --> 07:09.220 OK, and so much.
