WEBVTT 00:01.290 --> 00:01.930 Hi there. 00:02.730 --> 00:06.410 In this example, it looks pretty dangerous for us here. 00:06.550 --> 00:09.600 We can't make the apartment because the bishop is defending. 00:11.340 --> 00:16.080 So we seem to be under attack majorly in this position. 00:16.890 --> 00:19.210 If we take the bishop, we're going to get checkmated. 00:19.560 --> 00:26.640 So is this a desperate situation or can the interference tactic save the day here or even win it for 00:26.640 --> 00:26.920 us? 00:27.450 --> 00:34.740 In fact, there was a move which Tony Mon's, one of Britain's leading grandmothers at the time, played 00:35.130 --> 00:41.100 against Bridgeheads and actually won the game, which had actually resigned after this next move. 00:41.370 --> 00:43.060 I wonder if you couldn't find it. 00:43.090 --> 00:45.740 I'll give you five seconds, pause the video. 00:46.050 --> 00:49.380 It's a rather beautiful interference stall tactic. 00:56.180 --> 01:06.020 OK, so we really want to break down the communications of blacks position, there are communications 01:06.020 --> 01:09.260 between this point and this point, between this point in this point. 01:10.070 --> 01:16.970 And in fact, if we look at the intersection, we can do something rather cruel with one move based 01:16.970 --> 01:17.930 on that intersection. 01:18.830 --> 01:20.480 We can throw a spanner in the works. 01:21.530 --> 01:27.260 And you might ask the more discerning Spanish press might ask, where exactly do you throw the spanner 01:27.260 --> 01:27.760 in the works? 01:28.220 --> 01:35.870 Well, here and in many other examples, you look at the intersection point and actually further split 01:35.870 --> 01:36.170 of that. 01:36.170 --> 01:37.040 So which spanner? 01:38.000 --> 01:38.780 It's the bishop. 01:40.640 --> 01:46.280 Wow, and this connects essentially interferes with this point and this point at this point in this 01:46.280 --> 01:46.580 point. 01:47.060 --> 01:47.770 Of course it does. 01:48.680 --> 01:50.140 And the game actually ended here. 01:52.100 --> 01:59.180 If Rook eight takes a five, then that this connection as appearance Queen 67 is Chameides. 02:01.590 --> 02:04.300 And same with this one disconnects that key diagram. 02:05.280 --> 02:13.140 So what does Black actually do if Bishop takes B to check the wonderful thing here as bishop things 02:13.140 --> 02:20.010 B to renews that Friends of Queen 67 Chatenay Black has those key checks and it's important not to give 02:20.010 --> 02:20.800 the opponent checks. 02:20.820 --> 02:25.250 By the way, if you plan, you've got this, you ask him for Queen seats and getting chameides it. 02:25.800 --> 02:32.580 So there's no immediate major checks for black in Queen now, which doesn't do anything on this occasion 02:33.300 --> 02:41.160 and say the retreat's then blacks really in big trouble, for example, like this is a false checkmate 02:41.160 --> 02:43.500 sequence like this. 02:45.300 --> 02:46.800 So that's a forced checkmate there. 02:47.010 --> 02:54.690 So this really does for España in Black Swans, it's a wonderful example of indifference. 02:54.690 --> 03:04.640 If Bishop takes F5, then OK, G7 is defended, but this connection is broken. 03:04.650 --> 03:08.820 So Queen eats Chank Queen G six Jack. 03:09.540 --> 03:12.630 I'm the is actually mating so yeah. 03:12.690 --> 03:15.000 Bishop e5 a wonderful example. 03:15.600 --> 03:24.720 Finding that intersection point for maximum disruption of communication between the pieces actually 03:24.720 --> 03:27.690 spells a major disaster for black indisposition. 03:32.590 --> 03:40.110 So, yeah, very, very interesting and friends move, you might also ask Coton King's question isn't 03:40.200 --> 03:43.910 a really resourceful defensa informal queen 67. 03:44.710 --> 03:45.400 Yes. 03:47.250 --> 03:51.540 OK, we've got to be careful here if we take them, we're we in the background, we don't want to be 03:51.720 --> 03:52.410 cremated. 03:53.250 --> 03:54.300 Yes, good point. 03:54.300 --> 03:59.060 But we've still got some of the artifacts of the interference here. 03:59.460 --> 04:07.910 So, in fact, in this position, if we take with the queen, then we're not being back cremated. 04:08.730 --> 04:12.420 And this point is still not in touch with this point. 04:15.650 --> 04:23.800 So basically, if, you know, Bishop takes to attract the bishop out of danger, then quintets Yangcheng 04:25.160 --> 04:30.370 And we're back to the meeting after, so that's no good. 04:34.150 --> 04:39.040 And if the opponent does this, then actually, you know, we just take the bishop on this occasion 04:39.040 --> 04:40.160 and we're just winning here. 04:41.650 --> 04:44.140 So, yeah, all in all, it's absolutely crushing. 04:44.260 --> 04:46.840 Whatever black dance, however black slices. 04:46.840 --> 04:49.660 And this this is a really crushing interference. 04:49.690 --> 04:50.260 Over and over. 04:51.330 --> 04:53.620 OK, I will do that. 04:54.010 --> 04:56.020 It got something out of it too much.
