WEBVTT 00:00.930 --> 00:02.510 I them in this picture. 00:02.540 --> 00:05.380 I'd like to introduce you to the concept of the opposition. 00:05.700 --> 00:08.070 It's a form of zugzwang compulsion to move. 00:08.580 --> 00:12.210 So say in this position it is blacks turn to move them. 00:12.210 --> 00:13.400 Black is in big trouble. 00:13.800 --> 00:17.590 The compulsion to move when the kings are in opposition like this. 00:17.610 --> 00:19.790 So the kings are separated by one square. 00:20.070 --> 00:21.510 So it's a mutual blockade. 00:21.720 --> 00:25.650 But if black is forced to move, they're releasing the blockade. 00:26.220 --> 00:28.860 So say Kennedy thinks we can go here and win. 00:28.860 --> 00:32.840 This eighty six point G5 might drop off like this. 00:34.050 --> 00:38.390 So if they go to six instead, then we can go over this side of the border. 00:38.730 --> 00:44.400 So you can see that having the opposition when you have the opposition and it's the opponents tend to 00:44.400 --> 00:46.530 move, they have to get their king out of the way. 00:46.530 --> 00:50.070 They're kind of on blocking and blockading your king. 00:50.340 --> 00:51.560 It can be pretty lethal. 00:51.960 --> 00:55.530 Now, let's change the side to move. 00:55.950 --> 01:00.390 So I'm just going to play a move like this, which is inferior. 01:00.900 --> 01:09.030 And just to switch the sides, both sides, whites turn to move in this particular situation, one can 01:09.030 --> 01:17.130 actually hold here by keeping the opposition like this with King Efrain and Black. 01:17.160 --> 01:28.380 And also also hold this position now because black can be claver here and play king have sex and after 01:28.380 --> 01:34.020 Kingi for make sure that it's Wayne's turn to move when the Kings are in opposition. 01:34.530 --> 01:36.060 So the king is forced back. 01:36.150 --> 01:39.450 So you can see it's a very, very powerful tool for both sides. 01:40.320 --> 01:46.950 And the white king does not want to step back here because then whites kind of lose after King five. 01:47.400 --> 01:56.460 The white king can't blockade here and has to make way and whites kind of lose all the pawns on this 01:56.460 --> 01:57.000 occasion. 01:57.270 --> 01:59.280 Either way, the white king goes. 02:00.570 --> 02:07.650 So it's very, very important to know the tracks for keeping the opposition even to George. 02:07.650 --> 02:09.840 Sometimes it's very, very important. 02:10.500 --> 02:18.960 So just to recap here, King differe keeps the opposition in the case of King E5 that Black is forced 02:18.960 --> 02:19.560 to go back. 02:19.890 --> 02:25.920 And if Black doesn't want to lose hair, black can't go to ESX, believe it or not. 02:25.920 --> 02:31.020 Yeah, there is a resource to save this, which is actually King DC. 02:31.020 --> 02:39.660 So waiting for King e4e thinking ESX so you can see the sights to move can play a totally decisive role. 02:40.170 --> 02:45.060 So if you have the opposition and your opponents, King is forced to move out of the way. 02:45.690 --> 02:48.480 That can sometimes be really advantageous. 02:48.960 --> 02:53.250 And given that fact, you need to be very, very careful in such situations. 02:54.120 --> 02:57.480 You may be able to draw them depending on the particular position. 02:59.250 --> 03:05.100 So having the opposition is basically like getting the opponents king to move out of the way. 03:05.610 --> 03:08.460 So the opponent should have avoided this position from earlier. 03:10.200 --> 03:12.030 So I hope that's clear about the opposition. 03:12.420 --> 03:21.930 So just to recap, in the initial position as we set it up, if it's Black's turn to move, they've 03:21.930 --> 03:23.040 had it there. 03:23.040 --> 03:24.390 King has to get out of the way. 03:24.390 --> 03:29.490 It's a form of zugzwang compulsion to move when it's really, really bad that you have to move, you're 03:29.490 --> 03:30.480 damaging opposition. 03:30.810 --> 03:36.690 Total damage is done in the position to position because they have that compulsion to move out of the 03:36.690 --> 03:37.020 way. 03:38.250 --> 03:40.140 So say King dissects. 03:40.380 --> 03:49.740 To recap, we're going to just go on the King side and mop up, you know, the six pawn and then we're 03:49.740 --> 03:51.450 going to win that. 03:53.280 --> 03:59.190 And if they went to F six instead, then we're going to go to the queen side and this vivid example 03:59.550 --> 04:02.040 and we're going to win easily after that. 04:03.270 --> 04:11.550 And what we did in this example is artificially say, well, what if it was once to move in, this particular 04:11.550 --> 04:12.960 example would lose. 04:13.290 --> 04:15.510 So we set that up in all this move. 04:15.510 --> 04:18.840 Really, it's just to set up the position with Winstone to move. 04:19.170 --> 04:26.820 Now, we can draw this with the careful move, for example, with a careful move like King the three. 04:28.290 --> 04:36.120 And also, you know, King Afri would do either of those two moves would do because they prepare to 04:36.120 --> 04:42.720 get the opposition again in the event of King if King Ifrah in the Black Kings forced to also use the 04:42.720 --> 04:49.770 same resource King desex to make sure that the white king's going to be forced back so they can both 04:49.770 --> 04:50.640 draw like this. 04:53.290 --> 05:00.220 So I hope you can vividly see what's going on here, that you somehow sometimes have to sidestep diagonally 05:00.220 --> 05:06.410 like this with your king in order to create the opposition to get the opponents to go back. 05:06.970 --> 05:10.180 So if either side went vertically, it will be fatal. 05:11.150 --> 05:17.890 If the king goes like this or like this, then it's fine and it's it's nonfatal. 05:18.430 --> 05:24.940 However, if the king went vertically, then black would get the opposition and whites kind of losing 05:24.940 --> 05:27.990 by force if the king has to move out of the way. 05:28.000 --> 05:31.150 You know, a major weakness of the last move, dropping all of these points. 05:31.450 --> 05:36.020 And you can see the other way as well, you know, care for a major weakness while also getting out 05:36.020 --> 05:37.210 of the way, dropping all the pawns. 05:37.600 --> 05:46.420 So it's vital to sometimes have that opposition scenario where 05:48.910 --> 05:54.680 depending on the side to move, it can be fatal because your king's getting out of the way in a key, 05:54.850 --> 05:55.500 key manner. 05:56.320 --> 06:02.470 So I hope that's clear about the opposition and why it's important to consider in endgames. 06:02.680 --> 06:09.160 The power of zugzwang comes up quite a bit in endgames, the convulsions move and the opposition opposition 06:09.160 --> 06:11.890 as a kind of special kind of zugzwang. 06:11.890 --> 06:16.450 In a way, you can think of it like a special kind of Tsewang, OK, and so much.
