WEBVTT 00:01.230 --> 00:01.840 Hi there. 00:02.100 --> 00:05.070 And this is actually we're going to learn how to checkmate with just King and Rock. 00:05.310 --> 00:11.310 Now, let's say we have this position and this might be a position which we want to head to in the first 00:11.310 --> 00:13.470 place, but we'll look at more advanced examples like. 00:20.870 --> 00:24.440 Check there, and so that would be check, mate. 00:25.030 --> 00:26.430 So how do we do that here? 00:27.010 --> 00:27.880 Is it easy? 00:28.510 --> 00:29.850 Well, let's move the king here. 00:30.070 --> 00:32.100 Let's say King ain't no. 00:32.110 --> 00:34.360 We want to keep the king restricted. 00:36.160 --> 00:38.680 But the problem is they're a bit tricky. 00:38.680 --> 00:44.020 Only if we go here to try and deliver a checkmate, they just go there. 00:44.290 --> 00:48.430 And we definitely don't want to check now because the king will escape to that seven. 00:48.430 --> 00:54.990 Frank, you know, if we play this, then they're just going to go there. 00:56.200 --> 01:02.890 Now, that move is interesting because it's a kind of waiting move here and that's the kind of way to 01:02.890 --> 01:03.100 move. 01:03.100 --> 01:04.960 We want to wait for a disaster. 01:05.440 --> 01:08.390 If Kingi ain't, then that would be checkmate. 01:09.160 --> 01:11.590 So this waiting move is very interesting. 01:13.030 --> 01:18.060 So let's say now they go the other way, though, to try and run away, then we can do this. 01:19.000 --> 01:21.630 So now as soon as they go back, we can always checkmate. 01:21.760 --> 01:23.370 So they try and run away again. 01:24.490 --> 01:28.470 Then you go here, then they try and run away again. 01:29.710 --> 01:34.060 Then you go here and then they have to go back and they have to bounce back. 01:34.060 --> 01:35.350 And then you do the checkmate. 01:37.000 --> 01:44.140 So let's run that through again, but maybe even more efficiently based on what we know, if possible. 01:44.680 --> 01:47.270 So King here, we sent King E eight. 01:47.500 --> 01:49.840 Now let's not bother with King 86. 01:50.680 --> 01:57.040 We can actually do what we did more efficiently by introducing a way to move right here. 01:57.040 --> 02:00.160 Rook by seven, this is a key waiting move. 02:00.640 --> 02:02.590 So it's waiting for that disaster of King. 02:02.590 --> 02:04.980 The Einstein being is checkmate. 02:06.190 --> 02:10.990 So if they have to go back there, then here and any time they go out, we're going to checkmate. 02:11.500 --> 02:15.190 So we get a little bit more efficient than before that. 02:15.190 --> 02:17.440 The same bouncing from that side of the board. 02:18.220 --> 02:21.210 Once they reach that corner, they have to come back and then it's checkmate. 02:21.910 --> 02:27.670 So this is a basic example to get the general idea. 02:28.120 --> 02:38.830 You're restricting the king with your rook and you may need a key weighting move which helps the efficiency 02:38.830 --> 02:39.790 of the track meet. 02:40.270 --> 02:43.330 And a key one here is simply Rook B seven. 02:44.390 --> 02:52.060 This is more sensible than going on that side of the board in terms of efficiency because they could 02:52.060 --> 02:54.760 come over here and then they would be attacking or rook. 02:55.360 --> 02:57.520 It can still get a winning position here. 02:58.270 --> 03:02.740 But just remember, if we have this position now, we really need this way to move away from that. 03:02.740 --> 03:04.000 King would be seven. 03:04.390 --> 03:07.600 So saying to them, look, if you go there, I'm going to be eight. 03:07.930 --> 03:13.090 So again, they have to go back and then we end up checkmating them like this. 03:13.090 --> 03:16.330 It's an absolutely essential England Snowbowl. 03:16.330 --> 03:20.780 You might just be a rock up in the end and you need to know how to checkmate with the. 03:20.980 --> 03:29.350 So I hope you do master this position to start off with with friends, relatives, practice this position 03:29.830 --> 03:30.730 we've wanted to play. 03:31.000 --> 03:36.730 And if it's black to playing, I mean, it doesn't make too much difference. 03:37.390 --> 03:40.300 We've got the same principle of king here, king here. 03:41.080 --> 03:45.460 And then they would be chased back and they will be even easier if it was black to play because they 03:45.460 --> 03:52.330 couldn't go back because of Rook that checkmate or at least put arrows that if the king moved that you 03:52.330 --> 03:55.540 just move there and if they move there, then you just do checkmate. 03:57.220 --> 03:59.890 So it'll be even easier if they moved. 04:00.550 --> 04:10.720 Uh, let's say they go over here straight away and then they go here key whites in move so they can't 04:10.720 --> 04:17.500 go there because you Chameides somehow been getting the gist and then we get this opposition. 04:17.500 --> 04:23.890 The Kings are in opposition and that actually tactically means you're taking away the key escape squares 04:24.310 --> 04:27.060 and then you can do that checkmate. 04:27.250 --> 04:28.600 So it's check and mate. 04:29.560 --> 04:30.430 So very, very nice. 04:30.430 --> 04:32.380 I hope you practice that to perfection. 04:33.910 --> 04:34.570 That's very much.
