WEBVTT 00:01.050 --> 00:09.360 Hi there in his lecture, I'm going to try and answer the question, what makes a pool structure kind 00:09.360 --> 00:11.700 of strong or weak? 00:11.730 --> 00:14.610 What is a good -- structure in general? 00:16.700 --> 00:23.960 For me personally, a pawn structure plays in a serving role to give you good moves, basically winning 00:23.960 --> 00:31.970 moves and winning plans, if it doesn't serve you in that role, then it's like the tail wagging the 00:31.970 --> 00:32.450 dog. 00:33.080 --> 00:34.940 The pawn structure is your servant. 00:35.270 --> 00:39.830 If it doesn't give you winning plans and tactics, then maybe it's not very good. 00:40.400 --> 00:45.520 So here is an interesting, vivid example of pawn structure at work. 00:45.860 --> 00:53.510 Nigel Short against John Tymon in the 1991 Interpol installment, bound for e4e for Monju Short. 00:53.850 --> 00:57.920 So Nigel has been one of Britain's leading grandmasters. 00:58.610 --> 01:07.310 We have Knights have sex, the Annacone Defence Defense, the defence e 595 for Desex Mewshaw plays 01:07.310 --> 01:15.280 the modest Afri G Sex Bishop, C for Knight B Sex Bishop Be Free Bishop G7 Queene to. 01:15.500 --> 01:17.930 So at the moment the Portrush is pretty interesting. 01:18.800 --> 01:25.730 Why is content with a -- wench in a sense a slightly extra extra space see sex. 01:25.730 --> 01:36.170 Both sides castle we see here a treat which restricts that bishop so the pawn structure isn't a serving 01:36.170 --> 01:44.990 role here to give whites a comfortable edge in the centre space age, the bishop is blunted so the annoying 01:44.990 --> 01:46.340 pin doesn't have to be dealt with. 01:47.420 --> 01:55.250 So no horrors of a pin space or anything if we see a form stopping a form from blank. 01:55.910 --> 01:56.930 Details, details. 01:56.930 --> 02:00.290 And it seems as though Black's a little bit active lately for forcing move. 02:00.770 --> 02:04.010 Nineteenth Queen takes a blacks hitting that if form. 02:04.010 --> 02:05.480 That seems to be a vulnerable pawn. 02:05.840 --> 02:06.710 It's supported. 02:07.490 --> 02:11.000 And now esx this balance that Bishop C8. 02:13.610 --> 02:23.060 So interesting decision here, it was things perhaps that the bishop could be a target later if it was 02:23.060 --> 02:30.050 on air five and also why it potentially has sex so black is radically stopping e sex as a potential 02:30.050 --> 02:30.820 threat as well. 02:31.430 --> 02:32.960 But there are downsides. 02:32.990 --> 02:39.560 So is the pool structure making life easier for whites or for black hair? 02:40.190 --> 02:41.790 Well, this bishop is not very happy. 02:41.810 --> 02:43.730 It's blunted by the -- on sex. 02:45.140 --> 02:48.560 We have one shared file here, a two way road, potentially. 02:49.190 --> 03:00.140 Can white dominate this or can black dominate this within 90 to 95, like every Queen C5 and then Queen 03:00.140 --> 03:00.740 efore? 03:02.970 --> 03:08.940 The queen does have some interesting syncing options, for example, queen or maybe Bishop sings later 03:09.570 --> 03:13.650 going in for an attack queen before trying to parry things in advance. 03:14.790 --> 03:17.250 But now a very, very interesting decision. 03:17.430 --> 03:20.580 What goes into a kind of self penned in general? 03:20.580 --> 03:24.780 We shall do this, but it's just a relative penance, not an absolute pen. 03:25.050 --> 03:30.630 However, black can inflict on white structural damage and thus choose. 03:30.630 --> 03:34.640 So with night be sex choose to do so would not be sex. 03:34.650 --> 03:35.600 We seem to be free. 03:36.150 --> 03:42.570 This introduces this unveils Bishop Avery as a potential threat as well as supporting the bishop. 03:43.590 --> 03:45.680 Black takes the time to take that. 03:45.680 --> 03:53.260 That does cover the Avery Square against a free and whites actually hair place B to Seaforth. 03:53.280 --> 03:55.410 This keeps the Queens on the board. 03:56.030 --> 03:58.110 It is threatening Bishop Avery currently. 03:59.010 --> 04:07.440 And if we look at this position, whites, despite this fracture, despite having an isolated apelin, 04:07.830 --> 04:11.550 doubled C --'s Y is actually better. 04:11.850 --> 04:17.250 You have to ask the pawn structure who is it serving better here? 04:17.790 --> 04:19.980 Why it's much better here, why it's much freer. 04:20.340 --> 04:27.210 In fact, if this was European football, why is in a position soon to try to kind of take control of 04:27.210 --> 04:28.560 board by this default. 04:28.560 --> 04:35.400 If we can establish dominance of the default, that would be an interesting advantage in accumulating 04:35.400 --> 04:36.180 advantages. 04:36.450 --> 04:39.090 Like Williams, finance has approved of the idea. 04:39.090 --> 04:43.770 You want to accumulate advantages and it seems as though, well, actually, you know, structurally, 04:43.770 --> 04:45.870 surely this this really counts as a negative. 04:45.870 --> 04:47.040 You know, these pawns here. 04:47.940 --> 04:55.710 Well, if black was in such a great shape, couldn't you know, wouldn't this, Paul, try to be supportive 04:55.710 --> 04:56.720 of the aid? 04:57.360 --> 05:04.770 The thing is, Bishop afraid of queen bee the won't takes the default here of the queen for once, virtually 05:04.770 --> 05:13.950 taking this defo and here with this poor much on E5 has got fantastic attacking potential here, for 05:13.950 --> 05:17.310 example, like this by nineteen eighty six. 05:17.820 --> 05:23.580 But a fine, huge attacking potential is afforded to whites here. 05:24.390 --> 05:30.330 In a way we can feel that the pawn structure and in a real game, you know, you play in real games, 05:30.330 --> 05:36.240 you play, you might need to test the waters to see if it apparently really damaged structure either 05:36.240 --> 05:43.410 for you or your opponent gives amazing fun in terms of plans and winning moves, because that's what 05:43.410 --> 05:50.310 really is the role of a pool structure, is to support you to win games, not just to look good, not 05:50.310 --> 05:51.270 just to look solid. 05:51.840 --> 05:55.950 So we see here rookie eight, not of the eight. 05:56.460 --> 06:02.460 And now the one taking that defo this is like possession in European football where, you know, you 06:02.460 --> 06:04.230 don't just go and try and score. 06:04.230 --> 06:09.720 We try and keep possession, keep passing the ball around, wearing the opponent out, making them work 06:09.720 --> 06:13.650 hard, make them run all over the place by here on the chessboard. 06:14.070 --> 06:15.540 We're controlling the defo here. 06:15.540 --> 06:19.020 We've got possession is like positional, you know, possession. 06:19.830 --> 06:21.880 Quincy, five, four. 06:22.260 --> 06:23.100 Look at this queen. 06:23.580 --> 06:25.200 It's got great options. 06:25.230 --> 06:26.700 Look at this, bishop, great options. 06:27.180 --> 06:28.490 This bishops blunted this. 06:28.500 --> 06:32.700 Bishops blunted Wentz pieces have more scope here. 06:33.150 --> 06:38.670 We see B6 trying to give the bishops some scope on dayglo slight downside. 06:39.150 --> 06:44.610 If it leaves to go onto a more exotic diagonal, it will leave the seven behind. 06:44.610 --> 06:45.960 Sometimes this might be dangerous. 06:47.130 --> 06:51.770 So we see Bishop Efrain Quincey six and eight. 06:51.950 --> 06:56.460 So why is trying to weaken these dance squares by exchanging off that defensive bishop? 06:57.150 --> 06:57.980 Bishop H. 06:57.990 --> 06:58.430 Eight. 06:58.890 --> 07:03.840 If Bishop takes a six, her queen takes this situation. 07:05.850 --> 07:07.320 Why has a crushing blow? 07:07.320 --> 07:08.220 Rakti five. 07:10.330 --> 07:15.300 You know, I'm not going the major interference basic basically means the noise is free to help the 07:15.300 --> 07:21.480 queen without getting mated on to major interference stall tactic behind the scenes guarantees. 07:21.480 --> 07:25.320 Why it's kind of, you know, absolutely crush or jamai. 07:25.710 --> 07:27.240 The queen didn't go to ESX. 07:27.250 --> 07:35.280 Another example here, if Queen D7, Queen STS 87 is not as good as 1997. 07:35.670 --> 07:37.050 This is absolutely lethal. 07:37.150 --> 07:43.590 The Lefsetz checkmating Queen takes seven, doesn't go anywhere. 07:43.620 --> 07:47.940 And it's just enough for a perpetual check in this fashion. 07:49.110 --> 07:52.790 Critics say it looks tempting, but there's nothing actually there. 07:55.020 --> 08:04.380 But with Nighttime's H7, this is crushing Essex's the France, and if to have sex trafficking, queen 08:04.890 --> 08:06.310 is absolutely crushing stuff. 08:06.690 --> 08:09.810 So anyway, back to the game, Bishop Age sex. 08:09.810 --> 08:12.840 We see the bishop avoiding that exchange. 08:14.170 --> 08:20.060 So once controlling even more now is Bishop controlling seven and eight and now rook the eight. 08:20.520 --> 08:21.360 There should be seven. 08:21.360 --> 08:28.620 And look at that D7 square at sensitive black cannot resolve the situation without being background 08:28.620 --> 08:34.050 mated with the bishop g7 if rook eighty-eight then. 08:37.910 --> 08:44.250 So if Rook takes on a takes the eight route, takes the AIDS, have sex. 08:44.630 --> 08:49.190 This is just devastating of the F7 Queen takes the eight. 08:49.220 --> 08:52.280 This is just crushing stuff like this. 08:53.000 --> 08:59.960 So Bishop, G-7 was played this weekend, potentially blacks dance choirs, but white retreats that 08:59.960 --> 09:05.900 rock keeping the tension there, keeping possession, putting pressure on something so white dominates 09:06.500 --> 09:07.370 this default. 09:08.540 --> 09:16.640 Answer the question, if you can, please, which side's pawn structure is serving them better to give 09:16.640 --> 09:18.590 them winning plans and winning tactics? 09:26.290 --> 09:31.240 White's white structure is giving all sorts of fun, basically. 09:32.960 --> 09:37.900 Boils down to a lot of fun to be had for the opposition here, and in fact, after a Catholic bishop 09:37.910 --> 09:45.800 takes king, takes women for a breathtaking continuation, which makes this game kind of at the immortal 09:45.800 --> 09:51.320 level of the queen of six king kings, it seems as though I once got all the possession in the world. 09:51.320 --> 09:53.880 But how do we actually finish off the opponent? 09:54.410 --> 10:01.910 Well, if we look at the section of how we actually win games, either the opponent resigns, we could 10:01.910 --> 10:06.080 win on time, or actually there's another option we can make. 10:06.080 --> 10:13.880 The opponent, in fact, Nigel Shaw, has had the quotation that pulls a nice but checkmate, you know, 10:13.880 --> 10:14.570 ends the game. 10:14.570 --> 10:15.290 It wins the game. 10:15.860 --> 10:22.730 How can we do that here where we can threaten a deadly form pawn age for so threatening to have a deadly 10:22.730 --> 10:23.900 form borne by black players? 10:23.910 --> 10:27.740 H5 Black is not waiting for H5 86 Kwangju. 10:27.740 --> 10:32.780 Some might say black players age five just put that on board. 10:32.780 --> 10:39.170 If AIDS H5 Bishop B some 86 form -- will win the game. 10:41.510 --> 10:48.160 However, age five said, we're back to square one, are we square one, so to speak? 10:50.790 --> 10:58.050 Well, guess what the winning move is if I give you five seconds to pause video, you have complete 10:58.050 --> 10:58.710 possession. 11:00.870 --> 11:07.980 In this position, black is tied in knots, black cannot do anything constructive or fun, Black's position 11:07.980 --> 11:11.120 is locked up, blocked out, so to speak. 11:13.690 --> 11:20.660 Are with blacks position in locked up my usual place, King H2. 11:20.680 --> 11:26.950 And guess what, this king is quite a piece in this position. 11:27.340 --> 11:32.480 This is the mortal king walking free rookie, a king at four. 11:32.690 --> 11:34.930 There was a big threat of just joining the queen. 11:36.130 --> 11:39.910 The checkmate on G7 bishop is played. 11:41.590 --> 11:53.530 If King aged seven here, then 95 Czech and A takes f7 check is crushing of the 95 check from the rock. 11:54.550 --> 11:56.550 Seven is checkmate there as an example. 11:57.370 --> 12:02.370 And here if King G-8 then knights rook takes F7 as crushing. 12:03.910 --> 12:07.210 So for example rotates Queen six and seven and coordinates seven. 12:07.210 --> 12:10.810 Checkmate so black Bishopsgate. 12:11.020 --> 12:13.870 But now the King war continues and actually the game ended here. 12:14.620 --> 12:18.520 Black is in no way able to defend this position. 12:20.600 --> 12:27.800 If Bishop takes these seven, you know, black resigns, then king age six, we've made to follow. 12:31.570 --> 12:37.260 Yeah, and if King Eighty-seven, guess what, the power of the pen peso Paul is illusionary here, 12:38.080 --> 12:41.940 so which piece of pawn is absolutely pens? 12:41.950 --> 12:45.070 And so what is an illusion of the fence? 12:46.990 --> 12:51.250 The -- on F7 and spend the power of the pen, peaceful -- is illusionary. 12:51.640 --> 12:59.320 It's not really supporting sex we can play Queen takes Jesus, check her a sex check and in fact, we 12:59.320 --> 13:01.420 can land king of sex on this occasion. 13:01.900 --> 13:03.040 The King helping the queen. 13:05.570 --> 13:12.980 And if Queen takes her free check, gee, thanks, Bishop, thanks, we have queen checkmate, absolutely 13:12.980 --> 13:13.810 beautiful stuff. 13:14.420 --> 13:20.870 So when someone asks you about Paul structure being good or bad or when you want to think about pawn 13:20.870 --> 13:22.550 structure, you have uncertainty's. 13:23.990 --> 13:25.280 You can draw on this example. 13:25.280 --> 13:26.180 It's a vivid example. 13:26.180 --> 13:29.840 Sometimes you can accept Fracture's ugly. 13:29.840 --> 13:33.740 --'s look at the functionality is not all and how it looks. 13:33.740 --> 13:34.970 It's what it does for you. 13:35.090 --> 13:36.710 It's serving role. 13:42.960 --> 13:43.650 Does it make. 13:44.590 --> 13:48.770 Does it enable you to have winning plans and winning tactics? 13:48.790 --> 13:49.560 That's a key question. 13:49.570 --> 13:51.550 We all generally enjoy winning. 13:51.880 --> 13:55.100 That's generally the point of trying to learn about chess. 13:55.120 --> 13:57.400 We generally want to win games. 13:58.000 --> 14:03.400 So Portrush structures, you know, they are a good pawn structure is one which serves you well better 14:03.400 --> 14:04.190 than the opponent. 14:05.650 --> 14:07.480 OK, that's how much.
