WEBVTT 00:00.720 --> 00:08.850 Hi there in this clash on the show, you the Legal's meIt's passan, and in fact, this came on that 00:08.850 --> 00:13.690 show you features a reverse tango, which I've been playing quite a lot in recent months myself. 00:14.040 --> 00:18.800 This is actually from a correspondence game of David mooting against some bender. 00:19.410 --> 00:30.000 So after d5 E for D4 92, C see two rather that's disambiguate that both sides could have gone into 00:30.420 --> 00:31.650 if I like Jeoffrey. 00:31.680 --> 00:39.270 So the night as tangoed to this side of the board, we see not every F six bishop seafoam black relies 00:39.270 --> 00:48.900 and puts trust in a relative pin here and we actually get the Largos pattern quite early on in this 00:49.440 --> 00:49.850 game. 00:49.860 --> 00:54.810 Can you see why it plays here, which is a very, very powerful move indeed. 00:56.310 --> 01:01.800 And I have managed to play this a few times myself from the tango opening. 01:01.850 --> 01:04.080 I mean, it can happen in other openings. 01:04.740 --> 01:11.640 It's its amazing pattern, which involves very minor pieces. 01:12.300 --> 01:17.460 So the minor pieces, the bishops and lights, not the rocks and the queens, those are the major but 01:17.460 --> 01:18.450 the minor pieces. 01:19.140 --> 01:22.470 OK, so it's 1965 offering the queen up. 01:23.220 --> 01:26.540 So Black doesn't really want to take her because the queen takes G4. 01:27.210 --> 01:28.200 So we have Bishop takes. 01:28.200 --> 01:35.180 And the point is, can you see what won't please her if I give you five seconds, pause the video, 01:36.840 --> 01:37.470 OK? 01:41.110 --> 01:52.260 F7 Jack of the King s7, guess what, our tangoed knight actually delivers the checkmate. 01:53.350 --> 01:56.110 What a great have for the tango of 93. 01:56.350 --> 01:58.200 So clearly check out my tango. 01:58.200 --> 02:02.230 Of course you can actually play the tango in reverse if you want a system of white. 02:03.520 --> 02:11.620 So the tango can sometimes occasionally lead to the Largos checkmate pattern like this. 02:12.490 --> 02:16.000 So let's have a look at what makes up this pattern. 02:16.000 --> 02:17.200 A and bishop. 02:18.280 --> 02:19.650 A knight supports the bishop. 02:20.080 --> 02:22.170 The Bishop takes away and escapes choir. 02:22.180 --> 02:24.070 The knight takes white escape square. 02:24.400 --> 02:29.190 And this knight not only delivers the check, it's also taking away another key escape square. 02:29.560 --> 02:36.490 So sometimes the checks in themselves also take away key escape squares not to be taken for granted. 02:36.910 --> 02:40.650 The six pawn really helps her. 02:41.110 --> 02:46.540 Sometimes it's just a piece, you know, the fundamentals, the patterns, the mafia, whatever is occupying 02:46.930 --> 02:55.300 there, it's as long as it can't do anything about five checkmate and it doesn't matter. 02:55.510 --> 03:02.520 The basic pattern is there, the free minor pieces conspiring here to set up this lovely checkmate. 03:03.280 --> 03:05.020 So that's an example of that. 03:05.020 --> 03:07.420 It goes my pattern quite often. 03:07.420 --> 03:11.020 You will get it for a rebellion against a relative pin. 03:11.560 --> 03:13.180 So remember those relative pins. 03:13.630 --> 03:19.120 If you look at the rise of Bobby Fischer when he went mega tactical called Tactical Monster, he was 03:19.120 --> 03:22.500 rebelling against the relative spends quite a lot. 03:22.810 --> 03:24.730 If you look at his games, which I have. 03:25.570 --> 03:33.010 So that is part of your tactical tactical comment kind of understanding that your resolution of moves 03:33.010 --> 03:39.010 and possibilities, they open up, they have to open up for you to be more dangerous to opponents, 03:39.280 --> 03:43.860 not play routine stuff to think about rebelling against relative pens. 03:44.170 --> 03:50.680 And also yet this mating pattern, once you've seen it and you know it exists, you know that there's 03:50.680 --> 03:54.970 something potentially to look out for here, OK? 03:55.720 --> 03:56.350 And so much.
