WEBVTT 00:00.960 --> 00:01.560 Hi there. 00:02.040 --> 00:09.780 This example is from one of my favorite little games of all time, so Quintet's E5 has been played and 00:09.780 --> 00:12.270 it looks as though online spend and we're in big trouble. 00:13.020 --> 00:17.090 Bonce is a fantastic way out of this situation. 00:18.420 --> 00:26.220 Can we actually play something which is really magnificent here and could we actually calculate it? 00:27.100 --> 00:34.110 And in advance, as you only simplify it for you, I'm going to show you the next move, which set a 00:34.110 --> 00:40.780 major trap for the opponents with the opponent failing to know if the opponent played Queen E4. 00:41.070 --> 00:43.580 So this is Richard Reti against the very Tascosa. 00:44.220 --> 00:49.170 Then we play Rook A1, pinning the queen to the king just to put them on board. 00:50.430 --> 00:53.490 Ruki one would pin the queen to the king and not be winning for one. 00:53.850 --> 00:57.750 However, more subtle is 1984. 00:58.230 --> 01:02.880 But I like to use this example to reinforce the process of calculation. 01:03.180 --> 01:10.140 The in effect clause, the in effect clause basically says you don't just look or, you know, kind 01:10.140 --> 01:16.530 of staring at the move, just plate and its particular impact and implications on position. 01:16.530 --> 01:21.930 But you look at the whole board of facts, which could be the discovery of facts, the liberation or 01:21.930 --> 01:24.240 facts of other pieces involved. 01:24.690 --> 01:31.350 When you move a piece on a chess board, not only do you transfer energy from one point to another, 01:31.770 --> 01:35.370 thus creating a weakness of the last move. 01:35.880 --> 01:40.630 So say you move, you know Beshir from here to here, you've just neglected, you know, they're there 01:40.660 --> 01:45.840 that you you get a plus and you got minus for every single move. 01:46.080 --> 01:49.920 But also it's not that move in isolation. 01:50.670 --> 01:58.350 When you move a piece, that piece is obstruction to your pieces essentially and the opponents pieces. 01:59.130 --> 02:03.540 So there's a default obstruction property as well to factor in. 02:04.710 --> 02:10.380 And that's why sometimes when you exchange of pawns, your pieces become more active and aggressive 02:10.380 --> 02:15.390 all around the board, especially since --'s when the sense is clear, there's less obstruction. 02:15.960 --> 02:22.620 The obstruction factor, you know, the blocked in factor is very important to factor in to every move 02:22.620 --> 02:25.740 you play in your mind's eye, especially poor moves. 02:25.740 --> 02:28.140 You know, you shouldn't be just looking in that poor move. 02:28.530 --> 02:34.260 But the obstruction factor, what liberation occurred elsewhere around the board. 02:34.590 --> 02:36.390 You move a pawn over there. 02:36.390 --> 02:38.760 Hold on the say you've just opened up Bishop. 02:39.150 --> 02:40.680 That was obstructed by that pawn. 02:40.890 --> 02:42.130 We've over there, Bishop. 02:42.130 --> 02:44.010 We've you've closed one of their bishops. 02:44.610 --> 02:51.810 The obstruction or obstruction factor needs to be factored in of every move in the mind's eye. 02:52.530 --> 02:56.760 That's why this is one of my three golden rules. 02:56.760 --> 03:02.880 When you calculate weakness of the last move, killer common squares and the in effect, closing the 03:02.880 --> 03:08.640 whole position to factor in the defo obstructions or obstructions of every single move. 03:09.240 --> 03:17.670 Now, here, if we shackle checks, there's actually a remarkable check in this position which severely 03:17.670 --> 03:19.140 limits the opponent's replies. 03:19.500 --> 03:23.200 And so is actually your duty in your mind's eye. 03:23.200 --> 03:26.850 At least you don't have to play these out, but it's your duty to be aware of them. 03:27.120 --> 03:31.620 You must start with awareness, for example, of the opponents wrestling you again. 03:31.620 --> 03:35.580 Just to reinforce, you have to be aware of the opponent threats, just like you have to be aware of 03:35.580 --> 03:36.240 the opponents threats. 03:36.240 --> 03:39.660 You have to be aware of your forcing move opportunities. 03:41.280 --> 03:47.760 And here there's a magic foursome of opportunity which severely limits the opponent's replies, and 03:47.760 --> 03:54.600 it seems you have another check, but when you play the unchecked in your mind's eye, look at the defo 03:54.600 --> 03:55.620 obstructions. 03:57.690 --> 03:59.630 All the operations that occur. 04:03.630 --> 04:09.120 So I'll make it easy for you, the first outrageous charge for you to consider is Queen the check. 04:09.900 --> 04:12.750 So you might not wanna play this out in a normal game. 04:12.750 --> 04:14.890 You know, you don't want to be just giving your queen away for nothing. 04:14.910 --> 04:20.160 Some of these, you know, maybe maybe a lot of time, maybe 99 percent of the time they don't work. 04:21.630 --> 04:23.930 But that is what you do as a chess player. 04:23.970 --> 04:26.100 These are all variations behind the scenes. 04:27.430 --> 04:30.370 These help explain games, the variations behind the scenes. 04:31.470 --> 04:34.470 When I do UCP, people say, why have we gone into all these what ifs? 04:34.680 --> 04:39.300 Well, if you actually wanting to play tennis yourself, you'd need to know the variations behind the 04:39.300 --> 04:39.750 scenes. 04:40.000 --> 04:43.890 A lot of the time they're not working, but you need to be aware of them during an actual game. 04:44.100 --> 04:47.340 So it gives great empathy, at least to the players that played. 04:47.370 --> 04:51.720 They might have considered these variations, rejects them, and that's why they played how they played. 04:56.230 --> 05:00.050 So on this occasion, though, this is actually in this particular possession. 05:00.070 --> 05:03.580 I can tell you that this is actually a very good move on this occasion. 05:03.970 --> 05:06.930 But here, I want you to think about that in effect clause. 05:07.170 --> 05:11.590 So this is the third golden rule of calculation that I think is super important. 05:11.890 --> 05:15.850 And it is based on defaults, you know, are pieces. 05:15.850 --> 05:23.380 When they move by default, they're often obstructing or distracting, distracting, obstructing or 05:23.380 --> 05:26.300 liberating, I'd say liberating. 05:26.830 --> 05:31.030 So, you know, for example, here, if we play this poor move, we're kind of liberating the block. 05:31.030 --> 05:35.350 It's not just a pawn like controlling G5 that we move this. 05:35.350 --> 05:37.270 We're actually liberating the bishop. 05:38.080 --> 05:40.960 If we play this, we're actually blocking in this bishop. 05:42.250 --> 05:43.620 You know, you get the idea. 05:44.170 --> 05:50.140 Yeah, we're kind of by default obstructing or liberating moves. 05:53.690 --> 06:01.190 But in this position, there happens to be a move which is especially interesting, how it liberates, 06:01.400 --> 06:06.620 and at the same time a double whammy might create actually a killer common square. 06:08.610 --> 06:14.220 And this actually makes it one of my favorite little games of all time, can you see if you shackle 06:14.220 --> 06:15.120 checks now? 06:15.480 --> 06:20.660 So don't just check all checks by factoring the in effect clause on the entire position. 06:20.970 --> 06:23.310 So what checks do you have available? 06:24.010 --> 06:24.420 Yeah. 06:29.530 --> 06:35.260 There are two key checks and in fact, look at the liberation as well associated with them, the day 06:35.260 --> 06:38.040 for liberation or obstruction. 06:38.590 --> 06:44.540 There are two key checks as a check here and a check here. 06:44.540 --> 06:48.460 And actually there are double checks because they actually open up the rug, but one of them is a lot 06:48.460 --> 06:49.460 stronger than the other. 06:49.510 --> 06:50.590 It's actually Bishop G. 06:50.590 --> 06:53.070 Five is a lot stronger than the other one. 06:53.290 --> 06:54.550 I'll show the other one moment. 06:54.970 --> 06:58.210 But we can't access the king has to move because it's double check. 06:58.210 --> 06:59.530 That's a special double check. 06:59.950 --> 07:04.330 Really, really limiting the amount of supplies they can't obstruct because they're still in check. 07:04.810 --> 07:06.400 They can't shut them in check. 07:06.760 --> 07:08.080 They can't shut this because they still be. 07:08.530 --> 07:10.150 The king has to move on a double check. 07:10.930 --> 07:12.040 So the king moves. 07:12.040 --> 07:15.570 And now we've got this license to kill on a killer common square here. 07:17.290 --> 07:18.310 I hope you can spot it. 07:18.850 --> 07:19.960 It's Bishop the eight. 07:21.640 --> 07:26.080 And if the king had gone to Aetate, then it's the ain't checkmate. 07:26.410 --> 07:29.680 So this double check is far more powerful than the other one. 07:32.230 --> 07:39.460 So let's look at the other one, because in the end, the other way here, there is the king's got a 07:40.060 --> 07:40.960 on this occasion. 07:42.610 --> 07:45.430 So we can't really play this and the Kings also got AAA. 07:46.910 --> 07:48.700 It's far from being a checkmate. 07:49.030 --> 07:51.660 So, yeah, the way to do it is Bishop GFI. 07:51.700 --> 07:55.030 So that's why some checks are much, much better than others. 07:55.600 --> 07:57.310 Some checks are clear blue. 07:57.340 --> 07:58.030 Absolutely. 07:58.270 --> 08:00.790 You know, high clarity, no controversy. 08:00.790 --> 08:03.510 You want to find the best possible checks. 08:03.880 --> 08:08.410 So in fact, when you calculate, you know, check all the checks, some of them are so much simpler 08:08.680 --> 08:14.570 and achieve your goals, goals with so little fuss compared to others, it's unreal. 08:15.130 --> 08:17.540 So this is so much better than the other Chank. 08:17.560 --> 08:18.490 It's a double check. 08:18.850 --> 08:19.990 It opens up. 08:20.260 --> 08:27.700 The key thing to know is how it opens up that rook to give you a kalkhoven square and you only need 08:27.700 --> 08:31.380 a Caricom square in one moment and then you're winning the game with that. 08:31.420 --> 08:32.530 That's the end of the game. 08:32.950 --> 08:35.860 Like in this example, it's a pretty dramatic example. 08:37.720 --> 08:43.360 It's been nicknamed Suckerpunch on some sites, though, as though that was not seen this. 08:43.360 --> 08:51.850 Yeah, it's such a clear, nice, lovely forcing move sequence showing the beauty and power of the chess 08:51.850 --> 08:55.870 pieces working together and how they liberate each other with their movements. 08:56.620 --> 08:56.950 Yeah. 08:56.950 --> 09:03.970 So every time you make a move, Ukranian wings of the last move, sometimes you're combining with other 09:03.970 --> 09:09.670 pieces to create Caricom squares and the default liberacion or obstruction with every move as well, 09:11.240 --> 09:12.340 the bear in mind. 09:12.340 --> 09:16.030 So I hope this is clear enough that we want to look at the effects. 09:16.030 --> 09:20.380 We don't just want to be distracted by this move on some interfaces online. 09:20.980 --> 09:22.770 They'll show the, you know, the Arab Spring. 09:22.780 --> 09:25.000 You just look at that move is looking at what it does. 09:25.000 --> 09:26.290 You're not looking at the whole board. 09:26.530 --> 09:27.820 Go look at the whole board. 09:29.260 --> 09:30.940 These other pieces have been activated. 09:30.940 --> 09:33.640 They've been unlocked, unleashed, liberated. 09:34.000 --> 09:34.960 You're going to look for that. 09:35.770 --> 09:37.390 If you don't look for that, you missed that. 09:37.960 --> 09:40.000 Then you miss out on killer common scans as well. 09:41.110 --> 09:44.410 OK, I hope that's fairly clear from this example. 09:45.260 --> 09:47.020 The power of that and so much.
