WEBVTT 00:01.020 --> 00:01.560 Hi there. 00:02.160 --> 00:12.270 In this lecture, we see a very, very interesting example of a skewer and we want to link the skirt 00:12.270 --> 00:14.000 to actually a winning probability. 00:14.010 --> 00:19.140 There's no good doing a skill for skewers sake where you're not actually winning, you're just treading 00:19.140 --> 00:19.690 water. 00:20.190 --> 00:26.850 There's actually a very, very powerful winning skewer available if you play your cards right here. 00:27.720 --> 00:29.270 So I wonder if you can spot that. 00:29.730 --> 00:34.590 This is from a grandmaster game example, Nigel Short against Rafael Loganathan. 00:35.370 --> 00:36.210 So won't play. 00:36.240 --> 00:37.060 What do you think, Nigel? 00:37.060 --> 00:37.740 Short played. 00:51.350 --> 01:00.020 OK, the crushing blow is bishop, if I check, it's kind of detaching the king away from the queen 01:00.170 --> 01:04.400 so that now you can play, I hope you spotted this Quincey free check. 01:04.970 --> 01:08.480 So, yes, this is a royal skua, an absolute skua. 01:09.770 --> 01:14.630 The king moves and then black loses the queen. 01:16.220 --> 01:20.300 This is so much more effective than just a plain vanilla check. 01:21.860 --> 01:27.250 For example, Quincy Free Jack is just harmless, mostly homeless Camp seven. 01:27.950 --> 01:33.920 And so what it will be, you know, someone's obviously kind spending still, you know, but there might 01:33.920 --> 01:34.820 even be a draw. 01:35.090 --> 01:36.850 Usually Straub's accomplish things. 01:37.370 --> 01:41.630 So so essentially the skewer is really created here. 01:42.050 --> 01:46.850 The effective power, powerful winning skill is created by dragging the king here and they're still 01:46.850 --> 01:47.680 in alignment. 01:48.050 --> 01:52.100 This is the thing to note that on the same line. 01:53.090 --> 01:58.040 So if you're a user interface design specialist, by the way, in computers, you like things neatly 01:58.040 --> 01:58.610 aligned. 01:58.940 --> 02:06.830 Now, in chess, it's not sometimes good to have your pieces neatly aligned like it can lead to disasters. 02:07.160 --> 02:11.960 This alignment is bad in this case because of Queen suffering. 02:12.410 --> 02:18.500 It means that because your pieces are in the line, this tracking is picking up the other one, which 02:18.500 --> 02:19.730 is also aligned. 02:20.240 --> 02:25.760 So yeah, sometimes alignment of your own pieces can be a bad thing, but it's kind of encouraged her. 02:26.210 --> 02:26.630 Yeah. 02:26.630 --> 02:34.460 By this E5 So perhaps there were better moves for black to avoid this possibility. 02:35.840 --> 02:42.530 So but on the other hand, if Black Hand played kinky sex as a bonus puzzle, can you see what White 02:42.530 --> 02:43.570 could play here? 02:44.570 --> 02:46.850 And this doesn't look good either for black. 02:48.610 --> 02:55.110 OK, here we have it, just a double take a fork, and so they'll be winning. 02:55.720 --> 02:59.060 So, yeah, there was there was a method in the madness for that to allow that. 02:59.590 --> 02:59.920 Yeah. 02:59.920 --> 03:05.170 More subtle attack, more subtle tactics. 03:05.180 --> 03:13.660 So the game actually going on here in the game, it was this check and then black kind of was encouraged 03:13.660 --> 03:14.920 to align like this. 03:15.340 --> 03:21.730 And the alignment was kind of made use of by making this detachment of the king away from the queen 03:22.270 --> 03:22.660 and black. 03:22.660 --> 03:23.350 And she was there. 03:23.350 --> 03:27.750 But if it continues, you know, this is a beautiful skua example. 03:28.420 --> 03:32.470 So have you got that idea that Bishop E5 really, really nice. 03:32.470 --> 03:34.630 Bishop E5 crushing blow. 03:34.630 --> 03:37.060 They're emphasizing the power of a skewer. 03:37.510 --> 03:39.370 OK, that's a much.
