WEBVTT 00:00.850 --> 00:03.020 Hi there in this lecture. 00:03.030 --> 00:10.380 I would like to introduce you to the greenfield defense, so of the default might have things CIFOR 00:10.980 --> 00:18.930 G Sex Mitzy Free, unlike the King's InGen defense, which is Bishop D7 inviting, might set up a center 00:18.930 --> 00:28.320 of --'s abroad center --'s Yeonji play D5 and actually the Grunfeld defense is. 00:28.980 --> 00:35.730 It's one of those openings I really would not recommend to any beginner or even intermediate player 00:36.000 --> 00:37.910 unless you really, really know what you're doing. 00:37.920 --> 00:39.870 There are many books on the ground. 00:39.870 --> 00:40.380 Feel the fans. 00:40.390 --> 00:43.950 Some of the bridges are very, very tactical in nature and some raisons. 00:43.950 --> 00:48.720 You really do need to kind of, you know, know quite well. 00:49.290 --> 00:50.880 I hate to use the word Memrise. 00:50.880 --> 00:52.830 That's kind of a bad word in this course. 00:53.160 --> 00:58.410 This course is more about understanding the principles, the philosophies, ideally, which drive the 00:58.410 --> 01:02.610 principles which drive into the specific examples. 01:02.610 --> 01:09.420 But when we talk about the green, we really are going into very, very technical, very maybe, you 01:09.420 --> 01:11.160 know, you love technical stuff. 01:12.390 --> 01:16.830 And if so, you know, get back on the green field maybe at some point if you really want to play it. 01:17.340 --> 01:22.410 So D5 So this is just a very, very brief overview. 01:23.490 --> 01:27.390 It was used by Garry Kasparov against Anatoly Karpov with some success. 01:28.140 --> 01:33.360 He was having some issues playing the terrorist defense and switch that a Grunfeld in one of the major 01:33.360 --> 01:35.040 world championships they had. 01:35.460 --> 01:37.020 So that Battle of the Titans. 01:37.440 --> 01:45.030 So the main line exchange variation is SI takes the five black takes and then White plays E4. 01:46.440 --> 01:50.280 So this is the main line variation which many, many games have trodden through. 01:50.280 --> 01:54.960 You know, after nine takes beatings, for example, things start here. 01:54.990 --> 01:56.550 It's very, very interesting. 01:56.550 --> 02:06.360 Black is often putting pressure on white sensible moves like Bishop, D7, C, 596, etc. So default 02:06.360 --> 02:08.130 becomes a target. 02:09.030 --> 02:11.310 So that's the main line exchange variation. 02:11.910 --> 02:15.180 You really, really need to know what you're doing with both sides. 02:16.560 --> 02:23.730 Now, many years back, I had been recommending the so-called Russian system, in fact. 02:24.360 --> 02:35.970 So actually it's sort of takes the five you might want to potentially play Knight Afri and after Bishop 02:35.970 --> 02:42.360 G7 queen bee free teasing black about this DFI pawn to try and get them to take on CIFOR. 02:43.380 --> 02:45.260 And I thought this was an interesting system. 02:45.260 --> 02:51.390 It has its downsides that sometimes black can gain valuable, valuable time kicking around the queen. 02:51.930 --> 02:57.570 But on the upside, you sometimes get a nice pawn center, which can be dangerous and can lead potentially 02:57.570 --> 03:03.510 to a past -- sometimes in the censor, which can be super dangerous for black on a good day. 03:05.100 --> 03:08.130 So that Russian system is very, very interesting. 03:08.520 --> 03:15.660 And in fact, there's a lot of theory from this position with minor variations of the Black Castles 03:16.230 --> 03:19.620 E4 There's the Hungarian version of ASX. 03:19.980 --> 03:30.180 The SMEs love rational for the Prince Prince version of ASX Knight CSX recommended as the main line 03:31.650 --> 03:32.970 and 96. 03:34.200 --> 03:43.440 Also, if we go back to move for instead of knight Afri with that intention, you can actually without 03:43.440 --> 03:46.890 the intention of Queen before you can actually follow up here with Bishop G5. 03:47.280 --> 03:48.600 So this is the time in time. 03:48.600 --> 03:54.360 No variation names of the time off who famously lost to Bobby Fischer six nil and one of the world championship 03:54.360 --> 03:55.320 candlelights matches. 03:55.890 --> 04:05.700 So here a black complaint might efore and White can decide actually here between Bishop 84. 04:05.700 --> 04:08.670 This is one of the major options or C takes the five. 04:08.670 --> 04:15.930 So this is the time long version when White plays this kind of bishop G5 kind of provocative in a way. 04:15.930 --> 04:22.470 Is that provoking this attack on the bishop with Ninety-four so provocative by Bishop G. 04:22.470 --> 04:27.480 Five, if you want a more modest movement with the best of. 04:30.430 --> 04:41.500 And Iran is sort of actually afraid to actually play on move for a full year, and there's a very interesting 04:42.310 --> 04:48.280 line called the Grunfeld gambit of the G-7, Efraim Black counsels. 04:49.270 --> 04:50.740 And here. 04:52.950 --> 05:03.330 She takes the five, 1965, and Black is laying deliberately the C7 down, this gives black quite a 05:03.330 --> 05:06.270 bit of peace activity for that sacrifice -- sites. 05:06.270 --> 05:07.460 Grunfeld gambit. 05:08.220 --> 05:11.550 If they play for, we can go into that game. 05:11.610 --> 05:16.730 And interesting is that where, you know, it's not such a big deal losing the C7. 05:16.980 --> 05:22.770 So if a special effort really is being played with materialistic intention, it's not a big deal. 05:22.770 --> 05:25.510 Just run with it as the greenfield gambit. 05:25.860 --> 05:26.310 Yeah. 05:27.810 --> 05:32.190 So, yeah, very, very, very interesting opening. 05:33.690 --> 05:38.310 It's one which you really, really need to know what you're doing. 05:38.310 --> 05:43.980 If you enter into it, especially with the white pieces, you can expect your parents who have swallowed 05:43.980 --> 05:47.860 a book on it potentially as you get more and more experience. 05:47.890 --> 05:57.030 So this is why, you know, sometimes you might want to veer off in very interesting, weird and wonderful 05:57.030 --> 05:59.670 ways just to get the opponent to improvise. 06:00.390 --> 06:07.650 In fact, if you suspect, you know, they're going to play the football, they do play defensive or 06:08.160 --> 06:08.430 not. 06:08.430 --> 06:10.650 The Kings, they play the Grunfeld, the five. 06:10.950 --> 06:19.470 You know, you can actually play all sorts of things if you really are concerned just to get the book. 06:21.150 --> 06:24.510 There are other things which are not so efficiently names which could be dangerous. 06:25.410 --> 06:27.240 So just just bear that in mind. 06:27.570 --> 06:33.810 You don't have to follow this mainlined very as mentioned here, but these are the more established 06:34.170 --> 06:34.920 systems. 06:35.430 --> 06:40.020 So you might want to find your own movie alternatives by looking at various online opportunities for 06:40.020 --> 06:45.180 us and finding things which with a reasonable sample size, you'll make sure as a reasonable sample 06:45.180 --> 06:46.980 size and decent opponents. 06:47.220 --> 06:52.460 And it was a decent time limit, you know, just on bullet charts to base your decisions on. 06:52.740 --> 06:58.140 But, yeah, the established variations are interesting, but you really need to know what you're doing. 06:58.590 --> 07:00.840 OK, that's a much.
