WEBVTT 00:00.940 --> 00:01.600 Hi there. 00:01.630 --> 00:03.590 This is a very tricky one indeed. 00:03.610 --> 00:08.230 I have to say, you have to kind of remove the defensive hero before giving it another go. 00:08.470 --> 00:10.390 Your first go at this might actually fail. 00:10.390 --> 00:14.410 You might need to work out how was there any defensive hero? 00:14.590 --> 00:16.630 And that's part of the reason why it fails. 00:17.320 --> 00:22.390 So it's almost as if you do some analysis on the position and kind of do a post-mortem and say, what 00:22.390 --> 00:24.070 if there wasn't that defensive piece? 00:24.970 --> 00:28.900 And then you realize actually from the outset you could have nudged that defensive piece away. 00:29.330 --> 00:31.030 So this is a close to you. 00:31.050 --> 00:32.710 It's it's very, very tricky. 00:32.980 --> 00:36.310 But we can actually make use of pins here. 00:37.300 --> 00:39.250 It's a very advanced use of pens. 00:40.120 --> 00:43.970 So what do you think the crushing move is if I give you five seconds pause video. 00:43.990 --> 00:45.130 So very, very tricky. 00:46.390 --> 00:51.280 OK, the first crushing move is actually rookie six. 00:52.480 --> 00:59.290 And if you look at this, the queen has to stand by for the rook. 00:59.950 --> 01:02.200 We're making use of this kind of relative pin. 01:03.130 --> 01:04.930 So if. 01:06.090 --> 01:09.210 Offtakes we play rotates a fake check and we'll be meeting. 01:09.480 --> 01:10.680 That's pretty clear cut. 01:12.270 --> 01:15.090 So we nudged the queen away that way. 01:15.690 --> 01:17.810 And if the queen goes here, we're just taking her. 01:17.820 --> 01:18.570 You know, it's a weakness. 01:18.570 --> 01:19.120 We must move. 01:19.140 --> 01:21.720 The queen has to stay on duty over Efate. 01:22.080 --> 01:22.950 Can't go there. 01:22.950 --> 01:23.730 Same reason. 01:24.780 --> 01:27.450 So the queen hasn't got that many moves. 01:27.450 --> 01:32.070 And we can't take the to rotate the face of the queen stands guard on Efate. 01:32.940 --> 01:34.720 So what have we actually done here? 01:36.300 --> 01:38.110 We've created a weakness of the last move. 01:38.130 --> 01:41.540 We've created a kind of neglect of F7. 01:42.450 --> 01:50.670 And now how do we exploit both a kind of relative and an absolute pin with one move here, which is 01:50.970 --> 01:52.260 absolutely crushing? 01:54.660 --> 01:57.250 OK, can you hear what now you play? 01:58.770 --> 02:04.260 OK, it's Ruggie six, so there's an absolute ping going along here and it's a kind of roads have been 02:04.260 --> 02:04.510 here. 02:04.530 --> 02:06.300 So this is out of the question taking. 02:07.830 --> 02:08.680 So what does black do? 02:08.700 --> 02:12.570 There's only one kind of defensive resource, RUGGIE eight, and it's here. 02:12.600 --> 02:19.460 This is a weakness of the last move in the glass f7, but it only neglects F7 making a significant witness 02:19.480 --> 02:25.060 the last move because we've nudged that Queensway earlier and we can actually crash through with rotates 02:25.140 --> 02:25.770 f7. 02:26.580 --> 02:28.020 So we're threatening here. 02:28.500 --> 02:30.570 Chatterley, which is very difficult to defend. 02:31.050 --> 02:34.230 What Black can do is try a few checks. 02:34.740 --> 02:40.440 This Jack Kajita and now there is no check available on Bates. 02:40.920 --> 02:43.530 So this is why this is really tricky. 02:43.860 --> 02:46.770 That's the only check from the Queen, which is kind of legitimate. 02:47.640 --> 02:50.180 If Queen Desex, we're going to take Queen somewhere. 02:50.520 --> 02:53.370 But there is a check, Jeoffrey. 02:53.790 --> 02:55.950 Now, Black really is running out of checks. 02:56.310 --> 02:58.320 Black really can't handle this maiffret. 02:59.370 --> 03:03.270 So Black can try checking to try and drag the queen away. 03:03.270 --> 03:07.170 But we don't want to drag queen away because then route takes desex. 03:09.390 --> 03:16.860 So we actually move our king to H1 if we move our king to G. 03:16.860 --> 03:18.660 Well, I did tell you, this is tricky. 03:18.660 --> 03:24.480 I know this is a really unfair puzzle, but I mean, the follow up is you don't have to see all this 03:24.480 --> 03:24.890 follow up. 03:24.900 --> 03:30.990 I mean, you'd have to be a GM grandma to see this by this, you know, could cause some problems as 03:30.990 --> 03:31.290 well. 03:31.590 --> 03:34.530 Or doesn't it doesn't really. 03:34.530 --> 03:36.990 We aren't we are protecting Jeoffrey. 03:37.170 --> 03:40.050 More accurate is actually king age one. 03:40.560 --> 03:45.030 So and then the checks will run out like this. 03:45.030 --> 03:49.890 We can just move OKing over and then just, you know, take care. 03:49.890 --> 03:52.140 It's just checks per check sake. 03:53.280 --> 03:55.070 There's no real defense on H7. 03:57.930 --> 04:02.130 So, you know, can I get MITers so you might want to. 04:02.130 --> 04:04.680 OK, squasher what on earth. 04:04.680 --> 04:09.300 Like I did try on this and I found, you know this desex. 04:10.050 --> 04:10.380 Yeah. 04:10.390 --> 04:12.150 Why, why is this so different. 04:13.410 --> 04:15.930 Well the thing is Ruchi AIDS rotates. 04:15.930 --> 04:16.320 Yeah. 04:16.800 --> 04:18.570 Because we f7 is not available. 04:18.720 --> 04:19.140 Yeah. 04:21.010 --> 04:28.330 So thanks, guys, we can try rock left, but, you know, blacks got resources here if we try rock 04:28.330 --> 04:32.140 left to try rock for. 04:34.610 --> 04:38.480 I mean, on the surface, it looks a little bit as though this could be dangerous. 04:41.130 --> 04:53.230 But black can actually defend this way, for example, the one check and you know, Rook Desex says 04:53.250 --> 04:54.180 as one example. 04:56.410 --> 05:03.640 And if Ruggie for, you know, Jesus is defendable, I know this is a bit of a naughty, pretty advanced 05:03.850 --> 05:04.540 scenario. 05:05.110 --> 05:13.930 However, it does have Penns involved and it shows a kind of great application, a kind of killer application 05:13.930 --> 05:20.220 appends to take away the defensive heroes before you start getting to work on the Chapman. 05:21.310 --> 05:25.280 So that what that is what makes jazz so unbelievably hard. 05:25.300 --> 05:30.190 You know, this is why there's so many thousands of, you know, ratings in chess. 05:30.190 --> 05:31.640 Chess is not like north and crosses. 05:32.170 --> 05:39.730 There are seriously difficult positions where a certain player might see the increased subtlety of things 05:39.730 --> 05:45.850 going on rather than someone lower rated by the higher ratings might be able to knock out the opponents 05:46.270 --> 05:47.770 from this amazing rookie. 05:47.790 --> 05:48.060 Six. 05:48.060 --> 05:51.790 First, the lower rate players might be trying RUGGIE Sex and the opponent. 05:51.790 --> 05:53.800 Just offense, you know. 05:53.820 --> 05:56.100 RUGGIE And it's really inadequate. 05:56.110 --> 06:00.430 This attack, in fact, you know, desex immediately as well. 06:00.790 --> 06:04.980 We don't even have to run a check and blacks are actually going to be better off here. 06:05.740 --> 06:09.370 So, you know, sometimes there are tactics and there are tactics. 06:10.180 --> 06:18.430 But I'd like you to bear in mind that also sometimes you do calculations to gain an insight into a position, 06:18.940 --> 06:25.260 and that insight could be, well, what was the key hero and why it didn't work. 06:25.270 --> 06:29.170 Almost as if you've done a postmortem but with a vengeance, because I actually. 06:29.170 --> 06:29.710 Hold on. 06:30.040 --> 06:31.500 You haven't yet committed to that. 06:31.510 --> 06:33.070 It's only in the mind's eye, right? 06:33.550 --> 06:37.060 You only committed to that sequence of the mind's eye, whether it was the defensive hero. 06:37.630 --> 06:44.350 So because you haven't committed I mean, is there anything you can sort of adjust things, the outcome 06:44.350 --> 06:45.910 by removing the defensive hero? 06:46.030 --> 06:47.680 It's a very, very advanced one. 06:50.910 --> 06:55.810 Very, very tricky if you got this, you know, 10000 points instead of the usual thousand points. 06:56.250 --> 06:58.020 OK, thanks very much.
