WEBVTT 00:01.110 --> 00:01.760 Hi there. 00:02.480 --> 00:06.390 In this lecture, I'd like to introduce you to the concept of imbalances. 00:07.150 --> 00:08.250 These are the differences. 00:08.250 --> 00:12.090 You get positive and negative from a certain opening. 00:12.390 --> 00:18.750 So, for example, if we go into the so-called French defense and play nice Jeoffrey here, we're inviting 00:18.750 --> 00:23.520 this pen and this is going straight into the quinoa variation. 00:24.480 --> 00:28.800 And in this variation, there are sets of imbalances. 00:28.800 --> 00:35.580 Black has a superior pawns, rich White House double pawns, but White has a bishop on the square without 00:35.580 --> 00:36.300 a counterpart. 00:36.780 --> 00:46.440 So quite often the plans are to do of celebrating the positive imbalances or differences from the opening 00:46.440 --> 00:53.040 position, which is often aiming to, for example, celebrate this bishop sometimes with a pawn sacrifice 00:53.040 --> 00:54.870 or too many games of Bobby Fischer. 00:55.080 --> 01:02.250 He sacrificed his pawns to make sure that this positive difference in position is celebrated, especially 01:02.250 --> 01:05.510 without accountable, but also the extra space advantage here. 01:05.850 --> 01:11.850 And the pawn chain being an effective pawn chain also has opportunities later on dark squares, tactical 01:11.850 --> 01:12.600 opportunities. 01:12.900 --> 01:19.140 If you have a DFI pawn chain instead, then you're looking for like square opportunities. 01:19.530 --> 01:24.990 So say default have see for Jesus. 01:24.990 --> 01:27.630 And we go into the so-called King's engine, the fence. 01:29.040 --> 01:31.980 There are variations where White gets an interesting. 01:34.330 --> 01:36.490 Light, square advantage. 01:36.790 --> 01:44.770 So say this, possession with E 535 one as a square pawn chain and quite often, you know, like squares 01:44.770 --> 01:50.080 later are the way games are one tactic on the light squares. 01:50.410 --> 01:56.530 And because black has pawns on task, has also this pronounces aplan quite often that one often wants 01:56.530 --> 02:02.260 to try and trade off these bishops to amplify blacks line square weaknesses. 02:02.800 --> 02:09.520 So every plan, every pawn structure, every opening quite often has these imbalances. 02:10.810 --> 02:16.390 One opening, which you might say, well, doesn't surely the exchange French where you exchange here 02:16.660 --> 02:18.130 doesn't have too many imbalances. 02:18.830 --> 02:25.600 That's true, but it sometimes has a kind of pressure initiative which can still be meaningful and still 02:25.600 --> 02:26.920 actually went away. 02:27.190 --> 02:34.650 And sometimes black, you know, plays to really shake up things by putting the king on the queen side. 02:35.020 --> 02:41.830 So there are ways and means, for example, say like this, there are ways and means for black to actually 02:41.830 --> 02:45.840 fight for imbalances even though the pawn structure is symmetrical. 02:46.540 --> 02:50.050 But for me, you know, one of the more pronounced examples, and that's why I started with that. 02:50.050 --> 02:55.060 First, there's in the French defense, you know, the quinoa in particular to me is a clear example 02:55.450 --> 03:01.300 of imbalances in a position where, you know, blacks got the structure and whites got the bishops. 03:01.510 --> 03:03.880 This also happens in the engine, though. 03:04.060 --> 03:10.600 If we look at the names, the engine the fans wear, white also collects, in fact, the dance choir 03:10.600 --> 03:11.590 bishop quite often. 03:13.240 --> 03:18.400 So, for example, here, this situation, blacks got the structural advantage. 03:18.640 --> 03:23.130 But what has this dance, bishop, which could be dangerous later. 03:23.530 --> 03:30.220 So its job is to try and liberate the two bishops, especially this one, and prove that maybe the Kingside 03:30.220 --> 03:32.170 is weak later when black holes was Kingside. 03:32.650 --> 03:34.810 So there's a burden of proof. 03:34.810 --> 03:43.240 In fact, it's like two people are trying to argue their case for what the positive differences of the 03:43.240 --> 03:44.980 opening chosen are. 03:45.310 --> 03:50.380 You're trying to argue your case, and that's why just memorizing the storm moves might not be enough. 03:50.770 --> 03:56.620 You need to know kind of model games for where, you know, the bishop is liberated in some way and 03:56.620 --> 03:57.160 proven. 03:57.370 --> 04:04.210 If you can see example proofs, then you can base your plans based on those little game proofs and opening 04:04.750 --> 04:07.630 connects more intimately with your mental game. 04:08.590 --> 04:14.500 So these differences carry through to the mental game and even to the in-game echoes the end game. 04:15.190 --> 04:19.780 So every opening has these sets of imbalances when you play. 04:19.780 --> 04:24.090 This is set in defense against this Essendon offense is another example. 04:24.520 --> 04:30.820 So say the opensource in in defense, black is trading off a flagpole for a sensible and you might think 04:31.420 --> 04:34.750 this is actually good for and games in the future. 04:34.900 --> 04:37.810 Maybe if you know that lost the game. 04:37.960 --> 04:41.080 Sometimes there are ferocious attacks before that. 04:41.890 --> 04:43.090 So, say, in the night of. 04:43.300 --> 04:47.710 Yeah, both sides are trying to prove that imbalances quite often. 04:47.710 --> 04:54.820 The CFO has been used expertly by Bobby Fisher and the elbow square and all the perks associated with 04:54.820 --> 04:57.280 that CFO needs to be fully understood. 04:57.970 --> 05:05.530 And why has this defined pressure and sometimes can build up attacks on the Kingside sometimes later 05:05.530 --> 05:08.590 he's playing for queeny one queen jeoffrey queen for. 05:09.190 --> 05:16.780 But anyway, the point is the opening sets the set of differences that both sides play on. 05:17.440 --> 05:22.330 And both both players are giving themselves an education, quite often in different pawn structures, 05:22.900 --> 05:23.560 etc.. 05:23.860 --> 05:33.280 So these set scenes or Tubby's starting positions are great learning vehicles to play from both sides, 05:33.280 --> 05:38.890 sometimes, especially the pawn structure, which pervades in many, many different openings. 05:39.280 --> 05:41.980 They have their pros and cons to celebrate. 05:43.210 --> 05:50.920 So that's also something you want to celebrate the positive and dampen the negative of the opponent. 05:51.190 --> 05:57.490 So the concept of differences in general, you want to basically it's rather selfish. 05:57.490 --> 06:04.150 You want to celebrate the positive aspects and downplay the negative, whatever it exists from the opening, 06:04.450 --> 06:06.400 whatever pawn structure exists from the opening. 06:07.090 --> 06:09.910 So say you're playing with an isolated queen's pawn. 06:10.690 --> 06:13.960 You want to celebrate the positives and downplay the negatives. 06:14.410 --> 06:25.150 So say we have this possession and let's say we get an isolated queen's pawn when they play this and 06:25.150 --> 06:25.810 they play this. 06:26.770 --> 06:31.750 From Black's point of view, the positive favorable imbalances will be the blockade. 06:31.750 --> 06:33.700 Square 525 trying to. 06:33.950 --> 06:39.260 At this point, trying to simplify and maybe winning games where this pawn, this isolated queen's pawn 06:39.680 --> 06:40.250 is weak. 06:40.880 --> 06:44.200 So White is trying to use the upsides of this. 06:44.210 --> 06:51.440 I think ball like these hook squares, not that one, these squares, C5 and A5, this pressure on the 06:51.440 --> 06:58.340 EFO, the CFO sometimes is trying to create a battery here. 06:59.090 --> 07:01.900 And so you'll see that in the pawn section. 07:01.910 --> 07:08.960 In fact, some of the pros and cons of certain power structures which reflect more structural imbalances 07:09.200 --> 07:11.630 and that there's a range of these differences. 07:11.630 --> 07:18.380 You could think about the more long term differences which persist quite a lot throughout the game and 07:18.380 --> 07:22.100 the shorter kind of initiatives that way up in a bit of time of development. 07:22.430 --> 07:28.700 And they could evaporate unless they're stored translated into something else, they can evaporate quite 07:28.700 --> 07:29.190 easily. 07:29.660 --> 07:33.500 So the imbalances, you know, go from more static to dynamic. 07:33.740 --> 07:37.220 The dynamic sometimes only exists for a short period of time. 07:38.420 --> 07:43.550 So each opening has its, you know, favorable differences for both sides. 07:43.550 --> 07:46.100 And it's up to you to really celebrate hard those. 07:46.280 --> 07:49.750 And that's where tactics is a key instrument as well. 07:50.150 --> 07:56.740 If you're a brilliant tactician, then maybe a slight advantage you have in time in a particular moment 07:57.020 --> 07:59.610 gives you a winning attack if you play your cards right. 08:00.110 --> 08:06.710 So you have to be a major tactician to celebrate sometimes a small time advantage. 08:07.400 --> 08:13.190 But for the structuralists, the longer term aspects of the position that might be applied over several 08:13.190 --> 08:15.500 moves because the advantage is not going anywhere. 08:16.040 --> 08:19.240 It's there might be some weakness in the families pull structure. 08:19.250 --> 08:22.160 It's difficult for that weakness to disappear instantly. 08:22.550 --> 08:25.310 So imbalances take various forms. 08:25.520 --> 08:27.500 They have a short term to long term. 08:27.920 --> 08:31.490 And it's your job to play on your favorable imbalances. 08:31.490 --> 08:39.530 So a good plan is one which generally plays an on on your favorable advantages or imbalances. 08:39.750 --> 08:42.800 OK, so I hope that's kind of clear about these openings. 08:44.150 --> 08:50.300 And generally that's an interesting theory of openings in general to think about settlements imbalance 08:50.300 --> 08:50.660 theory. 08:51.320 --> 08:52.880 OK, and so much.
