WEBVTT 00:00.870 --> 00:01.710 Hi there. 00:01.740 --> 00:08.310 In this lecture, we see a gritty game Murray Chandler playing against Michael Adams in 1988, the 12 00:08.310 --> 00:10.050 Floyds Masters, Round ten. 00:10.050 --> 00:14.850 So Chandler Strong Grandmaster Ey four is played C6. 00:14.850 --> 00:19.950 So the Kraken is a great choice for positional players like Adams and Karpov. 00:20.070 --> 00:26.570 We have d4d5 92 D takes E for nine, takes E four now 97. 00:26.580 --> 00:31.740 So this is a very solid variation to exchange off without any structural damage. 00:31.740 --> 00:37.560 We have Knight G five, Knight d72, B six. 00:37.560 --> 00:40.350 We have nine 1 to 3 and now G six. 00:41.190 --> 00:41.970 Bishop D three. 00:41.970 --> 00:43.050 Bishop G seven. 00:43.980 --> 00:46.470 White Castles are now 96. 00:48.060 --> 00:52.580 So this has a view sometimes that a five might be useful to prompt c free. 00:52.590 --> 00:58.860 And in this structure, with a structure like this, there are undermining operations available. 00:59.100 --> 01:04.710 The most obvious would be at the base of the pawn chain with C five later, but less obvious would be 01:04.710 --> 01:08.670 somehow to get in b5b4 try and hit the pawn chain hard. 01:08.670 --> 01:13.710 We see rookie one black castles and now the pawn chain is set up C free. 01:14.160 --> 01:19.020 So at the moment it looks like it's a rock to the bishop. 01:20.190 --> 01:26.940 We have Queen C seven knights, E five if F six. 01:26.940 --> 01:31.080 In fact, there is a way for white to get a very strong attack. 01:31.380 --> 01:32.670 Nine takes h seven. 01:32.670 --> 01:34.530 This is a very strong attacking move. 01:34.860 --> 01:43.260 So if taking then the black king is exposed here, the cost of a knight for two pawns and for example 01:43.260 --> 01:48.960 here White's getting more material and it can end up with a brutal checkmate if instead of King takes 01:48.960 --> 01:54.840 h seven, if F takes e five again, there seems to be enough compensation for white here. 01:54.900 --> 01:57.000 The attack is very, very dangerous. 01:57.000 --> 02:02.430 After Rook takes e five, queen takes the G five if knight g four, rook h five. 02:02.430 --> 02:07.320 And it's a very dangerous scenario where the king's really kind of exposed. 02:07.980 --> 02:10.830 White does have an advantage here. 02:10.950 --> 02:18.510 So yes, that's the most dangerous response I've actually after f six to play knights hh7 if Queen bee 02:18.510 --> 02:19.920 free check 95. 02:19.920 --> 02:25.530 This is also dangerous for black, but to a lesser extent there still Knight takes H seven. 02:26.280 --> 02:30.270 So for example here Knight's FE Bishop takes G six. 02:30.270 --> 02:37.680 Again, White ends up being overall better if for example Knight take C four Bishop takes and then Black's 02:37.680 --> 02:47.340 game mated very dangerous scenario so we have 95 just letting the knights be like that 95 queen free 02:47.340 --> 02:58.110 and now Knight's five Queen Atria now H five Queen F3 Queen RD eight So this is really interesting. 02:58.110 --> 03:06.540 This this queen traits so black is defensively postured here H three and now a very interesting move 03:06.540 --> 03:09.480 indeed which reinforces and strengthens the position. 03:10.230 --> 03:12.420 So what do you think that is for ten points. 03:16.230 --> 03:16.710 Yeah. 03:18.030 --> 03:24.690 Well, previously this square had been weakened, and actually, strength is added to G six with Queen 03:24.690 --> 03:25.470 E eight. 03:26.490 --> 03:35.820 Not only strengthening the position somewhat, but also there's potentially holding C six is useful 03:35.820 --> 03:43.620 sometimes if Bishop D seven again won't can play quite forcefully here with nine G takes F seven as 03:43.620 --> 03:48.720 example, this position with g four ends up being better for Y. 03:48.750 --> 03:50.970 The attacking prospects are pretty strong here. 03:51.480 --> 03:53.010 So this is kind of nasty. 03:53.010 --> 03:57.720 So Queenie eight trying to stabilize strengthen the position, the g six weakness which had been weakened 03:57.720 --> 04:06.180 earlier from playing h five and we have now 9c4 and here things get really interesting. 04:06.600 --> 04:09.480 B five we have nines A five. 04:10.140 --> 04:15.720 So it looks as though, well, there's no undermining at the head of the pawn chain because of the d58 04:15.720 --> 04:16.710 for example. 04:18.860 --> 04:24.920 If needs e five here, then F six is possible because of that strengthening of G six. 04:25.100 --> 04:29.450 So this position is on sound for white. 04:29.600 --> 04:31.460 Black is adequately defended here. 04:31.610 --> 04:38.600 So 95 and we have for trying to undermine this rock against the bishop. 04:38.840 --> 04:42.120 If that bishop can come out to play, that would be good. 04:42.140 --> 04:44.330 So before we have Bishop DD two. 04:45.290 --> 04:49.370 If C four in fact nine takes the four of tempo is nice. 04:50.030 --> 04:52.250 Again, though, the position is kind of complex. 04:52.250 --> 04:56.910 White overall still has a nagging edge overall, even in that possibility. 04:56.960 --> 04:59.110 But Bishop DD two was played. 04:59.120 --> 05:02.390 We have Rook, the 8c4 might be six. 05:03.170 --> 05:08.120 And yes, this is a structure undermining offering C six. 05:08.120 --> 05:10.730 Here we have Bishop takes F five. 05:14.320 --> 05:15.620 Bishop takes five. 05:15.640 --> 05:23.860 So, yes, this is it looks a bit dodgy to give black the bishop hair, but winning the pawn here seems 05:23.860 --> 05:24.360 lucrative. 05:24.400 --> 05:25.480 Rokeby seven. 05:26.470 --> 05:30.340 And there's also another pawn potentially week before hand. 05:30.340 --> 05:31.570 We have be free. 05:33.850 --> 05:35.320 And now Rook see seven. 05:35.530 --> 05:37.090 And now Knight takes B four. 05:37.090 --> 05:42.640 So yeah, technically white is better here. 05:42.640 --> 05:44.530 This is a really gritty game. 05:44.920 --> 05:52.900 If D five then taking out the exchange and playing F6, this should be containing White's advantage 05:52.900 --> 05:55.630 if a counter exchange act to get rid of that knight. 05:56.140 --> 05:58.090 This would be only a small edge for white. 05:58.090 --> 05:59.800 So Knight takes b4. 05:59.800 --> 06:06.010 So at the moment Black does have the bishop parents compensation. 06:06.010 --> 06:16.180 We have Knight defray if Knight d5 this is possible and this position, it should be better here overall. 06:16.180 --> 06:23.380 But Knight rd free we have Bishop Tang's default so it's only a pawn down now. 06:23.380 --> 06:29.080 Black having the bishop and rook 81 and now Queen eight so not minding the Queen's coming off. 06:30.430 --> 06:36.850 So sensing the opponent might not like the Queen's coming off perhaps because they're an attacking player 06:37.030 --> 06:38.830 and they may have used a lot of time earlier. 06:38.830 --> 06:39.750 We have the move. 06:39.790 --> 06:47.920 Bishop F4, if Queen takes a this is a way to go, this position, for example, and then Bishop F4 06:47.950 --> 06:49.570 should be in White's favour. 06:49.570 --> 06:56.350 But Bishop F4 is played and we have Rook de seven and now see five. 06:56.350 --> 06:58.360 This weakens the D5 five square. 06:59.470 --> 07:01.210 So this is a bit of a theme. 07:01.210 --> 07:09.880 Sometimes they get these central squares in Adams games going on, so weakening d5 if Queen E to A for 07:09.880 --> 07:15.940 G for Bishop takes D free, this situation should be okay for white. 07:15.970 --> 07:22.640 Why it needs to be concerned about Bishop takes f two tactics, but it should be solid enough and one 07:22.660 --> 07:24.310 should be with advantage. 07:24.310 --> 07:29.140 But c five was played and now we have 95 and now 94. 07:29.140 --> 07:30.610 This is a bit of an inaccuracy. 07:30.620 --> 07:32.260 Throwing away any advantage really? 07:32.260 --> 07:40.240 Nearly if Bishop e5 Bishop takes Knight takes, this situation is still kind of interesting. 07:40.240 --> 07:45.580 Why has Knight takes F seven Hare Knight He takes F seven for this g for tactic. 07:45.580 --> 07:50.560 And again overall this should be this is the exchange up for why it should be better for white. 07:51.010 --> 08:01.450 But with 94 blacks in with a shot now and plays 90 C free and there's a lot of pressure on these pieces 08:01.450 --> 08:05.380 now that the centre has been kind of taken out. 08:05.620 --> 08:09.880 We have Knight take C free Queen takes free doubling White's pawns. 08:09.880 --> 08:11.560 Bishop take C free. 08:11.560 --> 08:14.020 And now this really makes things a lot worse now. 08:14.020 --> 08:19.810 C six so black from struggling is now with advantage of this. 08:19.810 --> 08:31.090 If knight e5 rook takes DD one rook takes the one, rooks should be even, but this just blunders the 08:31.090 --> 08:36.130 position away C six we have now Rook takes DD free. 08:36.130 --> 08:40.960 Yeah, the passport is not good enough here so we have Bishop takes E one. 08:40.960 --> 08:50.450 In fact, Bishop takes DD four is good as well because Bishop five is strong here and black speller 08:50.860 --> 08:52.960 but Bishop takes E one is also good. 08:52.960 --> 09:03.010 So black Bishop up four Not too many pawns, just one pawn C seven We have Roxy eight Rook c1f6. 09:03.010 --> 09:04.720 So it's just the bishop up now. 09:04.720 --> 09:05.940 Bishop takes H three. 09:05.940 --> 09:06.240 Yeah. 09:06.310 --> 09:12.580 It seems as though White is pretty distraught here and losing material, not even protecting h free, 09:12.580 --> 09:14.470 but yeah, they are a bishop down. 09:14.470 --> 09:15.700 So Bishop takes h three. 09:15.700 --> 09:16.420 This should be six. 09:16.420 --> 09:23.020 King of seven, Rook C four Bishop e six rook c2h for some nice pass pawn there. 09:23.590 --> 09:25.540 White's just giving up material for not much. 09:25.780 --> 09:28.480 Trying to get two connected pass ones, but they're a bit slow. 09:29.080 --> 09:34.330 Bishop d6b for rook eight and white here resigned. 09:34.330 --> 09:43.120 It is a hopeless situation if rook c1h3 this possession black can make progress on the diagonal for 09:43.120 --> 09:45.790 example like this making progress for example. 09:45.790 --> 09:47.050 This will be crushing now. 09:47.050 --> 09:54.640 So it's a fighting nitty gre nitty game here in the corner Con But if you play the Kraken, yeah, you're 09:54.640 --> 09:58.420 going to get attacking players going for you with Knight G five. 09:58.420 --> 10:04.210 So interesting moves for me in this game from a positional perspective, strengthening the possession 10:04.540 --> 10:08.200 at key points, which one has kind of been provoked to weaken. 10:08.410 --> 10:11.860 So White's manoeuvres with the queen kind of soon. 10:12.180 --> 10:14.460 Provoked JI six to be weakened. 10:14.460 --> 10:21.540 And it's fascinating that sense of weakness in the position to add the prophylaxis to where one has 10:21.540 --> 10:22.920 been weakened. 10:22.920 --> 10:29.490 So Queen to Queen E is a fascinating possession, but also tactically, of course, it threatens F six. 10:29.490 --> 10:31.770 So it's not just about in a theoretical sense. 10:31.770 --> 10:34.350 There's a there's a concrete fact here as well. 10:34.920 --> 10:36.180 F six potentially. 10:36.180 --> 10:43.410 So in the moving encouraged basically the undermining of the pawn chain, even if it cost a pawn, it 10:43.410 --> 10:50.250 seems in a from a practical perspective, White's position is loosened, the grip is loosened off, 10:50.430 --> 10:55.680 the pawn is won and with default coming off. 10:56.070 --> 11:02.400 Here, from a practical perspective, even if engines like white in some way it's become more difficult 11:02.400 --> 11:05.100 for white to manage this position. 11:05.100 --> 11:11.910 Black has solved a lot of the key issues in the position from a practical kind of human perspective 11:11.910 --> 11:14.280 and won't go severely wrong soon. 11:14.850 --> 11:15.270 So. 11:15.310 --> 11:16.380 Nancy Frey. 11:16.680 --> 11:21.390 Yeah, this is this is a terrible mistake. 11:21.690 --> 11:24.540 Coming up, this C six move. 11:24.540 --> 11:26.880 So White had to play 95 here. 11:28.350 --> 11:31.020 So fascinating game. 11:31.800 --> 11:32.760 Key mistake there. 11:32.880 --> 11:38.640 So Adams with the black pieces beating Grandmaster Murray Chandler in 1988 in round ten. 11:39.780 --> 11:42.000 So I hope you got some key points from it. 11:42.210 --> 11:47.490 Prophylaxis of key points undermining the structure, trying to you know, the bishop was kind of put 11:47.490 --> 11:51.060 against granite a rock, but the pawn structure was undermined. 11:51.060 --> 11:54.120 So good stuff from a few positional perspectives in my view. 11:54.150 --> 11:56.250 I hope you enjoyed it so much.
