WEBVTT 00:01.080 --> 00:01.660 Hi there. 00:02.190 --> 00:05.910 In this lecture, we see an absolutely amazing, amazing combination. 00:06.690 --> 00:09.690 I wonder if you can sponsor if I give you five seconds, pause video. 00:11.750 --> 00:19.580 So check all checks, pronouncements, the forcing moves, try and visualize in advance and. 00:21.390 --> 00:27.000 Just make sure it's absolutely checkmate, that there's no defensive resources, sometimes you might 00:27.000 --> 00:31.110 be thinking of another mating pattern, but if there's defensive resources, then it really doesn't 00:31.110 --> 00:32.360 work in your current position. 00:33.030 --> 00:35.940 The expression it all depends is very important in chess. 00:36.450 --> 00:41.590 It really has got to relate to your exact position, not some other position. 00:41.880 --> 00:48.510 So, yeah, OK, I hope you've worked out this amazing checkmate sequence, 10000 points of it, because 00:48.540 --> 00:49.770 actually it's quite tricky. 00:49.770 --> 00:55.380 Queen G-7 Chank Night takes rotates g7 chac. 00:55.470 --> 00:56.760 And here is the key points. 00:58.470 --> 01:00.450 A very, very important key point. 01:02.200 --> 01:08.260 There's something you must not be tempted by, especially if you've seen another baiting pattern, you 01:08.260 --> 01:12.520 must make sure the opponent doesn't have any defensive resources available. 01:12.880 --> 01:15.130 There is a way of doing that in this position. 01:15.610 --> 01:18.040 So which checks do you want to use? 01:18.040 --> 01:19.120 Check all the checks. 01:19.480 --> 01:22.210 Some checks are far less controversial than others. 01:23.470 --> 01:24.880 It all depends, as they say. 01:30.350 --> 01:36.140 Yes, I once asked Firuzan, a koban in Gibralter, the secrets of chess, and he just said, You know, 01:36.470 --> 01:37.430 it all depends. 01:38.540 --> 01:48.470 It wasn't very helpful but OK, we have here a killer move and it actually is a double check. 01:49.550 --> 01:50.450 This is a double check. 01:50.450 --> 01:51.800 It forces the king to move. 01:52.760 --> 01:58.980 And we'll know here that the bishop comes across this tigerland cutting across all the escape squares. 01:59.040 --> 02:07.160 And that is something in itself one should be excited about in the process of calculation for the availability, 02:07.160 --> 02:10.480 the probability of making use of a mating pattern. 02:10.760 --> 02:14.780 If you've got escape squares, covid, you're just looking for a can of CHAC. 02:15.140 --> 02:17.510 And here we have that with rooked one Chac. 02:18.170 --> 02:21.470 There's only technically 25 afterwork do 25. 02:21.470 --> 02:22.770 That is checkmate. 02:23.360 --> 02:28.010 So this happened in the game and of Ansen brilliant player, one of the best players of his time in 02:28.010 --> 02:28.910 1860. 02:29.150 --> 02:34.430 He was white against Berfield, silly, silly, not silly. 02:35.000 --> 02:37.280 And he didn't play in a very silly manner did he. 02:37.640 --> 02:44.000 If he played, you know, for example, you might be tempted by the mating pattern for mating patterns 02:44.000 --> 02:44.390 sake. 02:44.570 --> 02:46.550 But no, you know, black has resources. 02:46.550 --> 02:47.750 Our late night takes me two. 02:47.750 --> 02:48.740 It really doesn't work. 02:49.400 --> 02:51.500 So you need to find out what works and your obsession. 02:51.500 --> 02:57.590 And sometimes you need to check out even the most ridiculous checks, especially double checks, are 02:57.590 --> 03:03.620 always worth checking out in general because you're really fine tuning the opponents responses. 03:03.860 --> 03:05.870 You're limiting them to a king move. 03:06.410 --> 03:11.090 So once you investigate that situation, when you've got the escapes most covered, you know, this 03:11.090 --> 03:12.770 is the art of checkmate generally. 03:13.160 --> 03:19.730 Even if you're not, I don't think it's recommendable that you can go through 2011, make patterns your 03:19.730 --> 03:20.000 head. 03:20.120 --> 03:27.410 The fundamentals of mating patterns is essentially the art of taking Artscape squares and delivering 03:27.410 --> 03:28.760 the killer check on top of that. 03:29.390 --> 03:36.470 So in real games, the excitement level, your excitement level should go up once you see any escapes 03:36.470 --> 03:39.650 was taken up even in the process of calculation. 03:40.580 --> 03:44.630 So it's an interesting one to see this queen sack. 03:45.770 --> 03:47.780 This is a really beautiful combination. 03:48.560 --> 03:51.920 It's really fantastic if you start seeing this kind of thing. 03:52.340 --> 03:55.580 And fundamentally, if we look at this, we've got this semi open phone. 03:56.480 --> 04:01.130 I have a lot of fun and entertainment generally with Salmiya out and phones where you have a pawn missing. 04:02.180 --> 04:03.650 It's like one way traffic. 04:04.010 --> 04:06.170 It's like a one way road or motorway. 04:08.060 --> 04:09.740 And these are often very dangerous. 04:09.740 --> 04:17.630 So fundamentally, the position seems to me here to have some downsides for the black position in general, 04:18.110 --> 04:27.290 that focal point on G7 massively leveraged with this lovely double check from the bishop and the rock. 04:27.290 --> 04:31.550 It's a pattern well worth reinforcing, maybe even just playing for this example, just to make sure 04:31.550 --> 04:41.110 you reinforce these patterns at the back of your mind, they add extra kind of mating awareness when 04:41.260 --> 04:45.020 when when you're calculating variations, OK, and so much.
