WEBVTT 00:01.530 --> 00:02.140 Hi there. 00:02.160 --> 00:07.800 In this introduction lecture, I want to talk about another important real world metaphor teamwork. 00:08.130 --> 00:11.700 It's valued a lot in different disciplines. 00:12.450 --> 00:21.270 So if people work as a team and they take different roles, that makes often the sum of the parts is 00:21.270 --> 00:25.590 greater than what you'd expect if they work together. 00:26.400 --> 00:34.830 And in chess to checkmate, sometimes you need pieces in covering escape square roll, and other pieces 00:34.830 --> 00:39.240 will do the checkmate so division of roles and responsibilities. 00:40.470 --> 00:45.540 There is fantastic evidence in this course that a weakened king, the great attacking masters, when 00:45.540 --> 00:50.340 they have weakened the opponent's king, it creates huge teamwork potential. 00:50.340 --> 00:54.480 Those roles open up pieces can take away escape squares. 00:54.480 --> 00:58.770 Other pieces can come in for the checkmate as the two basic roles. 00:59.070 --> 01:06.750 But generally in one's attacking chess, one should be looking at the number of attacking pieces around 01:06.750 --> 01:12.180 the king and number of defending pieces to be able to overwhelm the defense as well. 01:13.710 --> 01:15.030 Not just the queen alone. 01:15.030 --> 01:21.270 Sometimes it's very tempting to sacrifice a piece, but there's only really your queen sometimes left 01:21.270 --> 01:25.530 or maybe another piece, but there's too many defenders and it ends up being nothing. 01:25.530 --> 01:27.930 That's the difference between a nothing attack. 01:27.930 --> 01:32.160 You know, if you've got other reinforcements coming in to the attacking party, that's the difference 01:32.160 --> 01:40.650 often between failure and success, the amount of teamwork potential, the amount of team you can get 01:40.650 --> 01:42.030 involved in the attack. 01:43.410 --> 01:48.270 So ideally outnumbered the number of defending pieces, the number of attacking pieces. 01:48.930 --> 01:52.380 And in the opening, usually you want to develop all pieces. 01:52.380 --> 01:53.640 That's like an opening principle. 01:53.640 --> 01:58.710 Hopefully you should be in such a position where if you are getting an attack, you haven't got pieces 01:58.710 --> 01:59.610 still asleep. 01:59.610 --> 02:01.140 They haven't been developed. 02:01.140 --> 02:06.090 You usually want to get all your pieces out, control the center, and then think about the attack. 02:07.020 --> 02:09.810 That's one of Sheryl's basic attacking formulas. 02:09.810 --> 02:14.340 Basically develop pieces control center, then think about that later. 02:14.340 --> 02:17.070 But it guarantees teamwork, certain level of teamwork. 02:17.070 --> 02:19.290 You can't have pieces that are asleep in bed. 02:20.160 --> 02:22.780 And there are many, many teamwork examples in this course. 02:22.780 --> 02:24.570 So look out for the teamwork. 02:24.600 --> 02:28.710 Now, here's a classic example, which is in much greater depth in detail. 02:28.710 --> 02:34.140 You'll see it's off playing against Karpov in 1990. 02:34.650 --> 02:39.320 So here Kasparov unleashes a really vicious attack. 02:39.330 --> 02:45.780 There are already pieces pointed in the direction of the opponent's king, and there's even been a bouncy 02:45.780 --> 02:46.440 road of attack. 02:46.440 --> 02:48.810 A rook has left it on that third rank. 02:49.500 --> 02:53.190 So we see strength playing an absolutely amazing move here. 02:53.820 --> 02:55.590 Can you guess 100 points. 02:57.330 --> 02:58.800 Don't worry too much about this. 02:58.800 --> 03:00.960 You'll see this game in detail. 03:00.960 --> 03:04.290 So Knight takes H six, taking out a key defender. 03:04.590 --> 03:10.320 So it kind of creates potentially much more dangerous threats on the H file by taking out a key defender 03:10.350 --> 03:17.280 is refused for a moment with c free if rook takes h six it's magical. 03:17.850 --> 03:21.570 Knight takes D sixes hitting the queen. 03:21.570 --> 03:22.700 Queen moves right? 03:22.710 --> 03:25.770 And then the queen G4 is actually very powerful here. 03:27.630 --> 03:32.450 So for example, Queen takes G4 off seven, Jack Knight takes age six. 03:32.460 --> 03:33.090 Check. 03:34.610 --> 03:35.480 And. 03:36.250 --> 03:36.610 Yeah. 03:36.610 --> 03:39.520 I mean, this this is absolutely tremendous here. 03:39.730 --> 03:40.570 If. 03:42.120 --> 03:42.290 Black. 03:42.430 --> 03:43.300 It takes her. 03:43.320 --> 03:50.610 Then this rook takes G4, check Bishop G6 and Y ends up getting the material all back with Bishop 65. 03:50.660 --> 03:51.330 Check here. 03:51.510 --> 03:52.860 Bishop takes B7. 03:53.010 --> 03:54.420 So it's absolutely tremendous. 03:54.420 --> 04:03.540 So if Queen takes G4 seven, check King G eight, Knight takes H six, check Knight 64 with a big advantage. 04:04.170 --> 04:16.140 So yes, it's kind of it's instead C phrase played by Karpov and we simply have F5 by taking out a defender. 04:16.140 --> 04:18.600 It's worth losing an attacker. 04:19.140 --> 04:25.140 And I know it's a lovely bishop in general on that diagonal, but it's sacrificed on this occasion because 04:25.140 --> 04:33.150 there's so many other attacking pieces in the team and there's less of a defending team, the offending 04:33.150 --> 04:35.390 team being stripped of that h pawn. 04:35.400 --> 04:40.950 Quite often when you take away the opponent's magical things happen tactically. 04:40.950 --> 04:47.970 So we have Queen G4 here Bishop and that lack of support means this is now a check. 04:48.390 --> 04:57.360 We have rook h6 if King G It's just very very dangerous here of the King H two with a big fat of G5. 04:57.360 --> 05:03.750 So for example G6 Knight G Fiber, you can see that lack of H4 means that without that defensive shield, 05:03.750 --> 05:05.730 White is threatening Queen H7 checkmate. 05:07.110 --> 05:11.700 And this position is going to be broken basically soon. 05:11.790 --> 05:14.730 For example, here plants getting absolutely smashed. 05:15.750 --> 05:19.170 But okay, let's let's go with it with Rook Brooke. 05:19.170 --> 05:21.380 H6 So another defender was removed. 05:21.380 --> 05:24.780 So there's only like the bishop around the king at the moment. 05:24.870 --> 05:30.300 King H two means that now Knight G5 can fly without this being check. 05:30.840 --> 05:31.620 This is wrong with that. 05:31.620 --> 05:34.380 Queen five So Knight G five. 05:35.190 --> 05:38.100 So here Queen F6 is played. 05:38.100 --> 05:43.830 It's only the Queen and bishop defending the king whilst there's one, two, three, four outnumbering 05:43.830 --> 05:45.150 the defenders here. 05:45.150 --> 05:51.780 So this is great teamwork from White's and we have rookie eight which is absolutely you know pinning 05:51.780 --> 05:55.860 the bishop and it's a forced mate coming up here. 05:57.570 --> 06:03.180 It's now a forced mate actually in eight and this was the first move it's a forced by knight which just 06:03.180 --> 06:07.860 shows that teamwork and you can get a fourth mate technically, even if you don't know it's an absolute 06:07.860 --> 06:12.990 force mate in a Bishop five Now, there was an optimal route to checkmate here. 06:13.060 --> 06:17.910 Kasparov chose Queen St's H six check and he won pretty soon after that. 06:18.060 --> 06:21.390 There's actually a false checkmate here with seven check. 06:22.440 --> 06:26.490 And here Queen takes 86 check and just. 06:26.490 --> 06:31.110 Bishop Sorry, Rook Thanks I And it's impossible for black to defend this. 06:31.140 --> 06:35.520 These guys are not really part of the defensive team of the king. 06:35.520 --> 06:36.930 They're too far away. 06:37.440 --> 06:41.130 And if 97 Rook takes a fight, for example, this is just. 06:41.190 --> 06:42.750 It's game over soon. 06:43.770 --> 06:45.510 So anyway. 06:45.510 --> 06:47.130 So there was a force to mate. 06:47.260 --> 06:54.000 Kasparov chose Queen St's H six, which was good enough for seven check and winning material. 06:54.270 --> 07:00.600 And he has to deal with this pawn of course, but that is soon dealt with here. 07:00.600 --> 07:06.090 Bishop e4 Czech Bishop takes the five Czech end of game. 07:08.150 --> 07:10.490 So, yes, 1965, that poll was taken. 07:10.490 --> 07:11.990 So it was a huge attack. 07:12.020 --> 07:14.120 You'll see this spectacular game. 07:14.270 --> 07:21.260 But you're also see, you know, wherever basically there's a king safety issue, how pieces can naturally 07:21.260 --> 07:27.500 take certain roles and responsibilities, especially taking escape squares, just generally outnumbering 07:27.500 --> 07:29.180 the opponent's defensive team. 07:29.180 --> 07:35.930 So you're attacking team in that sector of the board is your advantage, even if parts of your queenside 07:35.930 --> 07:40.550 are falling off or you're losing control on the queenside, If you're outnumbering the opponent, you 07:40.550 --> 07:44.150 have a relevant advantage for Champ mating. 07:44.150 --> 07:46.970 So it was a fantastic team effort in this game. 07:47.090 --> 07:55.730 So it's the 1990 Kasparov against Karpov Roy Lopez game Pretty amazing stuff but yeah in Kasparov games 07:55.730 --> 08:01.820 another great attacking players they usually develop their pieces optimally so they're out and about 08:01.820 --> 08:09.800 and it's ideal to either like both and both weaken the opponent's king and outnumber the defensive resources 08:09.800 --> 08:13.760 numerically to have that advantage around the opponent's king. 08:13.760 --> 08:20.120 You want your attacks to be irresistible, and that is a fundamental way that your attack is overwhelming. 08:20.120 --> 08:22.340 Just the numerical superiority. 08:23.060 --> 08:23.990 Okay. 08:24.660 --> 08:27.410 Hope you enjoy this example had so much.
