WEBVTT 00:01.490 --> 00:02.190 Hi there. 00:02.210 --> 00:06.110 In this lecture, we have a mega British encounter. 00:06.110 --> 00:10.310 Matthew Sadler, a very strong British grandmaster against Michael Adams. 00:10.310 --> 00:15.080 So this is a 1993 17 Floyds Masters Open Round ten. 00:15.230 --> 00:17.300 So D four from Sadler. 00:17.300 --> 00:23.480 And Adams actually repeats the Benko Gambit, which he had played against me in an earlier round of 00:23.480 --> 00:24.670 this same tournament. 00:24.680 --> 00:27.110 So interesting bit of trivia there. 00:28.760 --> 00:33.830 Matthew Sadler, Natasha Ragan, have a fantastic book, by the way, called Game Changer about neural 00:33.830 --> 00:34.360 networks. 00:34.360 --> 00:37.670 And we had a great discussion video on YouTube about that one or two. 00:37.670 --> 00:41.990 Actually, there's discussion of videos and yeah, great guy. 00:42.110 --> 00:54.050 So we have knights free from Sadler b4a free g6a tanks b4c tanks b4g Free Adams plays Bishop G seven. 00:54.320 --> 00:58.640 We have Bishop G two, both sides, Castle and now a five. 00:59.570 --> 01:04.430 Interesting thing is this structure kind of weak, fragile, overextended. 01:04.430 --> 01:06.170 That's for White's prove. 01:06.170 --> 01:09.380 We have nine BD two, Bishop B seven. 01:10.220 --> 01:14.960 It's that least that protects the rook puts pressure on white censor potentially that's useful Queen 01:14.960 --> 01:23.690 a four and now here we can see already that might be free and it could be interesting. 01:23.690 --> 01:31.910 For 1965 we have Queen C seven, D four and this also looks interesting to get in might be five as well. 01:32.540 --> 01:35.390 And also we have to look out for D six here. 01:35.390 --> 01:38.240 This looks a little bit scary sometimes. 01:38.660 --> 01:49.700 So D six is played at least preventing D six from white and we have 9b5, queen C eight and now might 01:49.700 --> 01:50.390 be free. 01:50.390 --> 01:51.170 Wow. 01:51.170 --> 01:52.920 So there is a weakness of the last two. 01:52.940 --> 01:55.180 It doesn't neglect c four, but white. 01:55.190 --> 01:58.280 It's trying to dismantle Black's pawn chain. 01:58.700 --> 02:00.470 Adams takes on C four. 02:00.860 --> 02:08.300 We have Knight takes a five, and now things get a bit crazy with in effect, a positional exchange 02:08.300 --> 02:10.490 sacrifice from Adams. 02:11.810 --> 02:20.420 He plays actually Queen Tangs E two if he didn't want an exchange sac Queen C eight So in exchange that 02:20.420 --> 02:22.160 a rook for a knight or bishop. 02:22.250 --> 02:26.270 When I talk about positional exchange, take this scenario for example. 02:26.990 --> 02:34.430 Black could end up losing a pawn though however of the bishop, a six might be three Queen B seven. 02:34.430 --> 02:36.920 There is a certain amount of compensation. 02:38.690 --> 02:40.650 Black does have a lot of peace pressure here. 02:40.700 --> 02:48.470 White has a small edge, but with queen size E to the forcing of 1987 is winning in exchange like BD 02:48.470 --> 02:56.450 seven is played not bothering with Rook seven because the bishop e free black can play a tactic or bishop 02:56.450 --> 03:01.730 see six here, but it's still amounts to a good position for for white. 03:02.690 --> 03:07.730 White can either just take this and allow rook ten C seven. 03:07.730 --> 03:12.620 This is a nice advantage for white or white can actually play queen. 03:12.620 --> 03:19.310 Thanks b4 here and this is a nice advantage for white D ten c six. 03:19.550 --> 03:27.580 So anyway like BD seven though is played so offering an exchange sacrifice 90 takes eight rooks ACA 03:27.590 --> 03:31.190 and there's also that annoying pin we have Queen takes B four. 03:31.220 --> 03:34.100 This is actually it's an intriguing inaccuracy. 03:34.550 --> 03:40.460 The Queen was actually useful on a four looking at D seven, so it actually ties black down a bit. 03:40.460 --> 03:46.760 There's no bishop takes the five because Bishop takes the 5.65, Queen takes D seven and we see after 03:46.760 --> 03:51.770 Queen takes before that kind of pressure is released on D seven it's hitting the bishop. 03:51.770 --> 04:00.320 But basically White could have played Bishop G five, which is funny enough an improvement in in a different 04:00.320 --> 04:02.450 variation for my game against Bishop G. 04:02.450 --> 04:06.020 Five here keeps black tied up. 04:06.020 --> 04:11.660 So if Bishop takes the five, Bishop takes D five and then D seven drops. 04:11.750 --> 04:20.330 Given that's the case we have, that's a knight C five, then Queen D one White will have technically 04:20.330 --> 04:21.350 an advantage here. 04:21.350 --> 04:25.640 This position is going into an advantage for white scenario. 04:27.530 --> 04:28.150 Okay. 04:28.160 --> 04:34.730 But the queen moved away from D7 and allows Bishop 65. 04:34.730 --> 04:43.100 And there's another aspect of this which amplifies the loss of the square control around why King is 04:43.100 --> 04:45.260 a useful tactical factor. 04:45.830 --> 04:48.230 That weight is a bit weaker now without the fear. 04:48.250 --> 04:51.530 Encanto Queen B 797 to be six. 04:51.530 --> 04:53.900 So this holds things up for the moment. 04:54.260 --> 05:01.500 Rook free the 896 Bishop He fights like a seven rook. 05:01.500 --> 05:03.200 C seven Now. 05:03.200 --> 05:06.320 Rook two should be about equal. 05:06.320 --> 05:08.180 This position should be about even. 05:08.180 --> 05:09.620 But Rook C seven was chosen. 05:09.620 --> 05:10.640 Queen B ain't. 05:13.660 --> 05:14.020 Queen. 05:14.060 --> 05:15.760 A6 is also interesting for Queen. 05:16.000 --> 05:20.230 For one, it should be slightly better overall, but Queen Bee. 05:20.230 --> 05:20.830 Eight. 05:21.070 --> 05:21.820 Nine RD. 05:21.820 --> 05:22.210 Seven. 05:22.210 --> 05:23.000 Queen RD. 05:23.050 --> 05:26.050 Eight again. 05:26.050 --> 05:26.560 Queen Bee. 05:26.560 --> 05:27.030 Five. 05:27.040 --> 05:31.330 Hair Just wanting the exchange of Queens and Queen 84 again. 05:34.060 --> 05:36.250 One should have a small edge but queenly. 05:36.250 --> 05:37.840 Eight And now an inaccuracy. 05:37.840 --> 05:39.070 Queen H five. 05:39.100 --> 05:49.660 It seems here that King G King G seven should be about even and the Queen, funnily enough, it's useful 05:49.660 --> 05:50.170 to stop. 05:50.170 --> 05:51.810 Might be five on this occasion. 05:51.820 --> 05:56.620 It's an interesting game where the queens on what they do, you know, in terms of prevention the queen 05:56.620 --> 05:59.290 is preventing might be five they're on E two. 05:59.440 --> 06:03.820 So it does seem engines suggest that the king move should be even. 06:03.820 --> 06:06.610 There's no nine be five and. 06:07.990 --> 06:08.830 In the game though. 06:08.830 --> 06:15.010 Yeah, this release is B5, but there is an intriguing idea now about trying to get a strong attack 06:15.010 --> 06:15.610 against the king. 06:15.610 --> 06:16.420 Potentially. 06:16.420 --> 06:24.610 We have Knight B five Rook B seven, Quincy eight Rook takes B five, Queen takes 37. 06:24.610 --> 06:26.500 The rook goes back to the back row. 06:26.590 --> 06:28.060 Rook a five. 06:29.290 --> 06:31.570 Now, here, if Queen a seven. 06:32.140 --> 06:37.360 This is also interesting for white actually Rook before Queen 897. 06:37.360 --> 06:38.710 Queen C 696. 06:38.710 --> 06:39.930 This should be in White's favor. 06:39.940 --> 06:44.470 This pendant it looks a bit annoying and that the rook is loose there right now. 06:44.470 --> 06:47.320 There's no King G seven without penalty. 06:47.380 --> 06:51.700 So, I mean, it looks interesting, but Rook, a five was played. 06:51.700 --> 06:53.260 We have Knights of six. 06:54.890 --> 06:58.520 And this hits the queen. 06:58.640 --> 07:01.250 So rebelling against the relative pain. 07:01.280 --> 07:04.760 Now Rook takes age five is played if Queen a seven. 07:05.480 --> 07:06.110 Guess what? 07:06.110 --> 07:07.520 Black can play here. 07:08.810 --> 07:09.980 Which saves. 07:11.740 --> 07:15.580 It's like, well, actually there might be one or two moves, actually might be fine. 07:15.580 --> 07:19.960 But one of the more interesting is Queen H free in this possession. 07:19.960 --> 07:25.390 So if Queen takes B eight, then there's 9g4 and White's getting in trouble. 07:25.390 --> 07:26.700 There is a forcing move. 07:26.710 --> 07:29.590 Queen takes F eight check, but it doesn't lead anywhere. 07:29.590 --> 07:32.620 The king comes out here and black's going to be better. 07:33.790 --> 07:36.370 So that's an intriguing variation. 07:36.370 --> 07:46.750 And in fact, Rook for Rooks is about even so, anyway, the queens traded off for each other, so Black 07:46.750 --> 07:50.200 is playing the exchange down for just one pawn. 07:51.430 --> 07:55.780 But there is pressure on B two, so it's an intriguing position. 07:55.780 --> 08:01.630 And now with F five, the King is actually getting a little bit better than the white king in a way. 08:01.870 --> 08:04.330 So Rook D one king of seven coming out. 08:04.330 --> 08:06.790 Bishop G seven Rook two. 08:06.790 --> 08:07.930 Bishop F six. 08:08.170 --> 08:15.130 So Black has a kind of fortress style position with White's extra pawn on this side of the ball kind 08:15.130 --> 08:17.170 of being stopped. 08:17.650 --> 08:23.650 So h four we have rook before rook a seven like e four and black is improving the pieces now. 08:23.650 --> 08:27.310 And in fact potentially now F two is under pressure. 08:29.080 --> 08:42.880 If Bishop takes B two, white can play Bishop four and here if rook four, rook takes E seven as example 08:42.880 --> 08:53.470 should be a simplification to an even position looks fairly even so 94 we have rook a two bishop d4 08:53.470 --> 08:56.410 looking at F two now B Freeze. 08:56.410 --> 08:59.560 Yeah, concessions have two, but there's 90 free. 08:59.560 --> 09:01.000 So 90 C free. 09:01.000 --> 09:05.590 Bishop RD two But now two pawns with exchange with rook takes be free. 09:06.790 --> 09:19.390 So sure if in any rook is taken then as a penalty here Bishop takes and then rook tanks or the other 09:19.390 --> 09:22.000 way knight tanks and then Bishop takes. 09:22.240 --> 09:25.690 But Adams just takes two pawns for the exchange. 09:25.690 --> 09:28.150 Now Bishop takes Bishop's take free. 09:28.150 --> 09:31.840 So Black's really got a stable position exchange down. 09:32.290 --> 09:35.440 So, Ruby six safeguards against Rook takes DD six. 09:35.690 --> 09:38.980 That's like tactical threats there. 09:39.790 --> 09:44.170 Rook dd five, Bishop f6h5. 09:44.260 --> 09:45.430 So this is intriguing. 09:45.430 --> 09:45.640 Now. 09:45.640 --> 09:53.620 King E six And here after wrote dd free first wrote B one check and now taking out H five. 09:54.040 --> 09:57.880 So this stops it being potentially dangerous. 09:58.300 --> 10:00.670 Is h pawn or just chipping out? 10:00.670 --> 10:02.050 G six Yeah. 10:02.050 --> 10:12.670 So taking out h five we have Rook a five, bishop E five and now F four bishop a one rookie free check, 10:12.670 --> 10:13.390 king of six. 10:13.390 --> 10:14.500 And now big mistake. 10:14.500 --> 10:17.590 Probably in big time trouble here, Rook seven. 10:17.590 --> 10:21.250 This looks like a time trouble mistake from move 50. 10:21.760 --> 10:23.500 This loses the exchange back. 10:23.500 --> 10:27.760 Yeah, it's a kind of forceable configuration if we look at this. 10:27.760 --> 10:34.120 So if rook a four instead staying off the dark square road of Dart Square Bishop on the other side of 10:34.120 --> 10:35.260 the road, so to speak. 10:35.800 --> 10:41.020 This should be only a small edge for black at this point, or equal. 10:41.050 --> 10:42.910 Equal or small edge. 10:42.910 --> 10:48.520 But it's easy for waiting to go wrong here in this scenario, even though once exchange if for example, 10:48.520 --> 10:56.170 Rook eight for let's just say fictionally like this check and an E five happens, then all of a sudden 10:56.170 --> 10:58.450 Black's position is really springing into life. 10:58.810 --> 11:07.600 You know, this could be afforded you know, this starts to get dangerous for white rook free as example. 11:07.600 --> 11:12.370 And black's got small edge you know there's a target on G free a dark square target. 11:12.370 --> 11:19.270 Yeah it's it's better for black slightly so but with rook seven this is bad news Bishop d4 so getting 11:19.270 --> 11:29.140 the exchange back so rook e takes e seven if rook any takes e seven taking on e free and h four Black's 11:29.140 --> 11:34.210 got a big advantage here with h four using that to undermine the structure here and the king can cozy 11:34.240 --> 11:37.930 up coming g6852g4 potentially. 11:37.990 --> 11:50.710 So so rook e takes e seven first the check, then another check, then taking out a seven. 11:50.710 --> 11:52.210 So the rooks improved here. 11:52.210 --> 11:53.530 So that was nifty. 11:53.650 --> 12:01.540 If the king had gone to G one, then that's bad news because of Rook, a two check and then picking 12:01.540 --> 12:03.760 up an entire rook after. 12:03.940 --> 12:10.450 So the king is kind of taken out to an unfortunate square. 12:10.780 --> 12:13.360 e1a little bit further from the pawns. 12:13.360 --> 12:19.270 Bishop takes seven, Rook takes rook G two, Rook takes H7 Rook takes G free. 12:20.200 --> 12:25.150 We have King F to Rook G4 six. 12:25.180 --> 12:26.320 Jack King E seven. 12:27.310 --> 12:28.390 King F three. 12:28.570 --> 12:29.350 H four. 12:30.890 --> 12:33.330 We have King E three, D five. 12:33.350 --> 12:33.680 Yeah. 12:33.680 --> 12:37.270 This end game is unpleasant for white and it's a bit of a grind. 12:37.280 --> 12:44.840 So King G seven, five King G, six rook chains check dd four The pawns are making progress. 12:45.260 --> 12:46.550 So Rook D eight. 12:46.550 --> 12:50.360 Yes, the pawns are making progress here. 12:51.200 --> 12:56.570 And there's also, you know, an idea that if rook takes Rook g four looks very good. 12:58.310 --> 13:02.450 That's kind of overwhelming for the king here to have to catch both pawns. 13:02.450 --> 13:03.980 It's too late for the king now. 13:04.100 --> 13:11.420 So yeah, we have rook d instead d Free rook d five. 13:11.420 --> 13:17.690 And now Capablanca like getting the king much more aggressive King h five rook takes F five king G four 13:17.690 --> 13:20.660 King's very aggressive rook, a free check. 13:20.960 --> 13:23.060 And this is actually the end of the game here. 13:23.060 --> 13:27.260 So the Thunder resigned if King e1h free this position. 13:27.260 --> 13:30.140 H two This is overwhelming that h pawn is very strong. 13:30.140 --> 13:31.490 It's going to be herded through. 13:32.270 --> 13:32.720 Yeah. 13:32.720 --> 13:38.480 An intriguing game, a real fighting game between and they're still the one and two basic on the British 13:38.480 --> 13:40.610 ranking list at the time of this recording. 13:40.610 --> 13:48.830 So these are really great British grandmasters, banker gambit, very dramatic intense struggle of a 13:48.830 --> 13:49.400 game. 13:49.850 --> 13:52.190 But there are some positional considerations. 13:52.190 --> 14:01.160 Positional exchange sacrifice helps Black get a very lively game for the rook and yeah, lots of rich 14:01.160 --> 14:02.780 counterplay opportunities. 14:02.780 --> 14:06.110 So an absolutely fascinating game, very complicated game. 14:06.200 --> 14:13.280 But yeah, this was a transitioning into a more simplified scenario where there's a lot of compensation. 14:13.280 --> 14:14.300 Black hats here. 14:14.870 --> 14:18.140 Okay, I hope you enjoyed this one answer much.
