WEBVTT 00:00.930 --> 00:01.770 Hi there. 00:01.800 --> 00:08.510 In this lecture, we see Michael Adams against Richard Burton in 1988, the 12th Lloyd's back Masters. 00:08.520 --> 00:13.890 So we have ey four, Richard Britton, C five, play, C five. 00:13.890 --> 00:17.340 This is an and we go into a nine off variation. 00:17.340 --> 00:20.820 So nine f6 90 3a6 The Sicilian Najdorf. 00:21.120 --> 00:25.020 We have Bishop e3e6 Queen dd two. 00:25.020 --> 00:30.960 Bishop e7f3 90 6g4 97. 00:30.960 --> 00:34.950 So this is the English attack system, popular with English grandmasters. 00:35.730 --> 00:42.900 So, yes, the the set up has the same as what you use against a Sicilian dragon in the main line. 00:43.350 --> 00:51.150 So we have Queen C seven, King B one, D, E five, Bishop two, B five. 00:51.420 --> 00:55.260 Now, this is a really interesting situation. 00:55.260 --> 01:00.150 There's actually a phenomenal resource available, which we know now with modern engine technology. 01:00.360 --> 01:05.760 In this position, Adams plays a move which seems actually to give a lot of passport potential. 01:05.760 --> 01:09.120 So a lot of passport potential already. 01:09.120 --> 01:11.030 We can see that in the possession. 01:11.040 --> 01:13.230 Forget about attacking Kings for a moment. 01:13.230 --> 01:17.430 There's a free to pull majority and it's kind of amplified with Adams's move. 01:17.430 --> 01:24.900 Knight takes B five and David Bronstein has played similar such sacrifices to just try and get a lot 01:24.900 --> 01:26.150 of pawns for a knight. 01:26.160 --> 01:31.170 It turns out here, there's an incredible resource in 95. 01:33.440 --> 01:37.850 You might wonder, what on earth is this about if castling just rule out castling? 01:37.850 --> 01:42.090 Knight takes E seven check and Queen 66 is great for white. 01:42.110 --> 01:47.690 So the critical test E tanks Knight RD five big tempo gain one pawn. 01:47.690 --> 01:50.060 But it's really a vicious position here. 01:50.060 --> 01:52.370 This knight is super dangerous. 01:52.610 --> 01:59.330 If we look at, say, Bishop Fe rook hg1 and let's say black tries the castle on the queenside f4 we 01:59.330 --> 02:03.290 can allow Knight C for just take and hear Queen C free. 02:03.530 --> 02:06.860 So at the moment the trend is going up and up here. 02:07.760 --> 02:10.310 We've got one pawn for the piece now. 02:10.310 --> 02:13.610 Bishop Be6 Rook, two pawns for the piece. 02:13.610 --> 02:16.430 And look at the first rank here. 02:16.730 --> 02:19.550 Compared to Black's fold rank, compare third ranks. 02:19.550 --> 02:21.980 White can do rook cliffs here. 02:21.980 --> 02:29.690 So for example G six, rook D three bishop e seven rook be free Queen eight, Bishop a five. 02:29.930 --> 02:35.090 And this position is just going downhill essentially because of this pressure on the black position. 02:35.090 --> 02:36.940 This is actually going downhill. 02:36.950 --> 02:41.990 For example, here, Queen f six, check another pawn and you can see Black's pacified. 02:42.230 --> 02:44.720 It's a remarkable resource. 02:44.720 --> 02:46.130 Nine and five. 02:46.430 --> 02:48.230 But yeah, Adams play is an interesting move. 02:48.230 --> 02:52.370 Anyway, he takes b5a takes nine, takes B five. 02:53.300 --> 02:56.420 Now Queen A five is technically an inaccuracy. 02:56.420 --> 03:03.020 Queen B eight seems more stubborn, but Black is faced with free pass pawns. 03:03.050 --> 03:13.640 Over here it seems potentially black could get enough to hold it with G five to lock these pawns. 03:13.640 --> 03:17.480 So say this position h five to try and cause trouble. 03:17.600 --> 03:22.070 And here it's about even as example. 03:23.980 --> 03:27.260 But yeah, it's easier to play for white with the pawns in general. 03:27.280 --> 03:28.060 We have Queen. 03:28.060 --> 03:32.380 A five queen takes a five, rook takes a five, Bishop B six. 03:32.380 --> 03:38.190 This wins essentially an exchange and makes things worse for Black Rook takes B five. 03:38.200 --> 03:40.120 If rook A for B free. 03:40.120 --> 03:41.590 Where is this rook going? 03:41.890 --> 03:45.790 So if it goes back to eight, nine, C seven, Shaq picking up the rook. 03:45.790 --> 03:49.090 So the rook really has to give itself up. 03:49.210 --> 03:54.910 Bishop takes B5, Bishop B seven, Bishop e2g5 Rook d2 f6. 03:54.910 --> 04:00.010 Now to Richard Britton's credit, and I played Richard Bryn Actually I played some games. 04:00.010 --> 04:04.700 I beat him once actually in one of the the London classics. 04:04.720 --> 04:05.740 Very, very interesting player. 04:05.740 --> 04:09.340 But to his credit, he does play extremely well here. 04:11.340 --> 04:16.860 Each five would also be interesting for f five this position to technically be about equal. 04:18.150 --> 04:23.010 But f six we have a four king d7b free. 04:23.610 --> 04:26.520 So that keeps the light out of c49, G six. 04:28.140 --> 04:29.880 We have Rook HD one. 04:30.810 --> 04:31.830 King eight. 04:32.340 --> 04:33.330 Bishop C four. 04:33.330 --> 04:35.800 So probing here might have four. 04:35.910 --> 04:38.040 Bishop B 595. 04:38.700 --> 04:39.750 A number of F one. 04:39.750 --> 04:40.350 H five. 04:40.350 --> 04:44.010 So black's really doing quite well considering here. 04:44.010 --> 04:45.470 G takes rook takes. 04:45.480 --> 04:52.740 We have a five rook h free blacks trying to create their own past pawn potential with this, this pawn 04:52.740 --> 04:54.000 and this pawn potentially. 04:54.000 --> 05:00.300 We have a six bishop 8fd1 which threatens rook takes d six. 05:00.330 --> 05:00.500 Yeah. 05:00.510 --> 05:05.160 The king's safety is also an issue here D five is played very, very good move D five. 05:05.460 --> 05:07.020 I mean it's logical looking as well. 05:07.020 --> 05:11.400 If Knight takes a free this is a disaster for Black Rook takes D six. 05:11.400 --> 05:16.290 How does black stop rook d eight if rook eight rook d seven. 05:16.290 --> 05:25.860 And the thing is here, black's in big trouble because let's, let's say this ignoring the knight for 05:25.860 --> 05:28.610 a moment, there's rook D eight check. 05:28.620 --> 05:29.190 Make that. 05:29.190 --> 05:30.420 So what does black do here? 05:30.420 --> 05:37.110 95 Because the front here is rook c seven check. 05:37.110 --> 05:40.230 And if King ba7 is checkmate if knight. 05:40.620 --> 05:45.840 So if 95 here he takes let's just put this on the board. 05:45.840 --> 05:48.000 A seven would be strong in this position 05:51.780 --> 06:00.810 and here Brooks C seven Shaq rook B seven check and then mating so it's very difficult So D five very 06:00.810 --> 06:02.700 good E tanks, E tanks. 06:02.700 --> 06:03.300 C four. 06:03.300 --> 06:05.430 So trying to blast through the D file. 06:05.430 --> 06:08.370 But Black is getting now a past g pawn. 06:08.370 --> 06:10.290 So this is a game about pass pawns. 06:10.290 --> 06:17.640 Both both sides have passed pawn potential rook c two rook takes d five technically better for just 06:17.640 --> 06:18.630 an even possession. 06:18.630 --> 06:22.680 This possession 92 check is an important trick for rook to be free. 06:23.100 --> 06:27.840 So this position and here it should be about even. 06:27.840 --> 06:35.460 But rook c two we have d4c5 95 that D five squares is good to use. 06:35.460 --> 06:45.630 King a15a7 Bishop F six and now rook D three is play, but actually black's doing rather well. 06:45.720 --> 06:55.200 But please g for rook eight would actually be prophylaxis in effect against this pawn queening. 06:55.740 --> 07:04.950 So for example here let's imagine g four rookie to like g five let's follow through rook f to 94 let's 07:04.950 --> 07:09.150 imagine rook takes f five Check, check. 07:09.150 --> 07:10.440 Taking out the bishop. 07:10.440 --> 07:14.190 We reach scenarios like this that are better for black. 07:15.240 --> 07:19.410 Yeah, it's difficult for one here, but g four is a mistake. 07:19.410 --> 07:24.330 When bishop a six checking d7c6 check and now King E six is a mistake. 07:24.360 --> 07:30.120 Technically, there's better things to do, but C seven is played. 07:32.980 --> 07:39.070 Bishop a five was interesting here for a big advantage instead of C seven. 07:39.370 --> 07:45.970 So why is that different if Bishop E five, C seven and then we're taking out a piece? 07:45.970 --> 07:46.360 Yeah. 07:46.360 --> 07:51.760 It's safeguards the position to play bishop a five hair. 07:55.210 --> 07:57.370 And it's difficult to see what. 07:58.250 --> 08:00.590 Black is doing for a moments. 08:00.590 --> 08:03.530 White is also practicing Bishop B seven. 08:03.530 --> 08:08.420 So the night is not hitting the bishop and it gives time for this bishop be seven for. 08:08.540 --> 08:10.550 So that's like one of the key points. 08:10.550 --> 08:12.770 So anyway, see seven immediately. 08:12.770 --> 08:18.920 And also the bishop's hanging here, it's taken C eight, nine, six, eight. 08:18.920 --> 08:30.680 Rook takes the eight and now rook H eight, B four king D seven, rook C five and now pass pawn is created. 08:30.680 --> 08:32.600 The G pawn passport is created. 08:32.600 --> 08:34.700 Bishop Check King E seven. 08:35.930 --> 08:37.370 Bishop B seven. 08:37.700 --> 08:41.510 Now here is an absolutely critical point in the game. 08:43.130 --> 08:47.090 Black is wanting to get a queen and plays g free. 08:47.120 --> 08:47.840 Big mistake. 08:47.840 --> 08:51.350 Rook, age eight, is actually really quite good for black hair. 08:51.740 --> 09:00.350 So as example, King Bee won just to get out of the firing line with Bishop 95 and play Rook free. 09:02.420 --> 09:04.820 So it looks as though, hold on, this is big trouble, right? 09:04.820 --> 09:07.450 Because isn't white queening the pawn? 09:07.460 --> 09:16.460 The thing is this position black can get ready to take off White's pawn potential and two exchanges 09:16.460 --> 09:16.730 down. 09:16.730 --> 09:18.680 But this is a winning position for black. 09:19.040 --> 09:25.010 So this position is absolutely it's a win for black because of the two connected pass pawns. 09:25.010 --> 09:27.920 So for example here g three and winning. 09:28.250 --> 09:31.160 So this is a great demonstration for black to win with the past pawns. 09:31.160 --> 09:40.670 But G4 a huge mistake because after Bishop takes eight g Rook H one check King B to g two Adams just 09:40.670 --> 09:50.030 can't just just takes on free and off to G one sorts out King safety issues just taking on H one and 09:50.030 --> 09:54.740 here rook C eight and there's no key checks which help black hair. 09:54.830 --> 09:56.870 Black's going to be the exchange down. 09:57.230 --> 10:02.810 So Queen G to check is try King A free doesn't even matter if King B free is used. 10:03.080 --> 10:06.890 So say this position queening taking on D free. 10:06.890 --> 10:08.810 White's got a big advantage here. 10:09.170 --> 10:18.500 But King a free is chosen queen F one and white lets that rook go queening Queen takes the free king 10:18.620 --> 10:23.660 a four queen rd one check King B five Queen E to check King B six. 10:25.050 --> 10:26.910 King of seven and now Rook F. 10:27.480 --> 10:34.440 And the Queen of the Rook G centralizes nicely with Queen D five, Queen H five and Rook G one. 10:34.440 --> 10:41.130 So that big central queen on D five is supporting Rook H one King h61, Bishop H four. 10:41.130 --> 10:45.270 And now Queen takes DD four Vicious. 10:45.270 --> 10:47.000 We have Bishop D eight check. 10:47.010 --> 10:50.100 And has Adams messed up here with the rook? 10:50.100 --> 10:51.060 Not really. 10:51.060 --> 10:54.360 The point was Queen takes a and black has to resign. 10:54.360 --> 10:58.890 If queen takes h one queen h h check and then queen takes h one. 10:58.890 --> 11:02.340 So an intense game about past pawn potential. 11:02.670 --> 11:04.500 It's fascinating. 11:04.500 --> 11:08.910 You know, this is a very, very popular opening for British grandmasters against the Sicilian knight 11:08.910 --> 11:13.110 off as if same set up against the Sicilian dragon. 11:14.310 --> 11:19.560 So it's interesting the richness of the position here. 11:19.890 --> 11:26.370 So off the B five, this is an incredibly for size excited engine move 95. 11:26.370 --> 11:34.230 To be fair, it seems you have to be treating this as a positional knight sacrifice to just dominate 11:34.230 --> 11:39.300 position and eventually see that the third rank is really good for attacking the opponent's king. 11:40.350 --> 11:47.400 Yeah, that's kind of a sci fi move, like a five, but details B five is a theme which has been seen 11:47.400 --> 11:50.430 in many human games before, particularly David Bronstein. 11:50.430 --> 11:53.910 So this winning exchange, it was very, very dangerous situation. 11:54.030 --> 12:00.120 Richard Brennan, to his credit, created some significant counterplay and on a better day, might have 12:00.360 --> 12:03.090 beaten Adams if he had a bit more luck here. 12:03.090 --> 12:09.030 But yeah, it's about being very, very careful about the opponent's resources and sometimes letting 12:09.030 --> 12:11.340 the opponent queen before you. 12:12.090 --> 12:15.720 Is important not to rush the queen like the opponent, sometimes queen before you. 12:15.720 --> 12:24.780 But yeah, it's, it's a very, very intense struggle this game but shows that past pawn potential and 12:24.780 --> 12:30.030 the fun of trying to unlock unlock the passport potential and combine it with King's safety issues. 12:30.030 --> 12:34.680 It's very, very interesting conceptually of the game, so I hope you're inspired by it. 12:35.190 --> 12:35.970 That's very much.
