WEBVTT 00:00.960 --> 00:01.670 Hi there. 00:01.680 --> 00:06.060 In this lecture we see Anatoly Karpov playing against Vishy Annan's in 1991. 00:06.060 --> 00:07.020 The candidates match. 00:07.020 --> 00:12.960 They had it in round eight, so we see D four from Karpov D five, C four, C six. 00:13.410 --> 00:15.540 So we're going to a semi Slav variation. 00:15.540 --> 00:16.800 So 93. 00:16.800 --> 00:17.760 E six. 00:17.970 --> 00:19.690 e397. 00:19.710 --> 00:28.110 Now the weighting move Queen C two So why it doesn't want to play Bishop de Fray because black has dc4 00:28.560 --> 00:34.920 and this generally equalizes so Queen C two is an interesting weighting of trying to get the bishop 00:34.920 --> 00:35.820 to go to D six. 00:35.820 --> 00:44.730 Basically, if Bishop e seven white can consider be free and have potentially a small advantage. 00:44.730 --> 00:54.450 So Bishop D six Bishop E to both sides, Castle D, C for Bishop C for Queen E seven and now a free. 00:54.450 --> 00:56.640 So this is an interesting move in itself. 00:56.640 --> 01:02.700 From a positional perspective, Karpov is not committing to E four, which would be very, very tempting 01:02.700 --> 01:11.820 for a lot of players and after e5h free black can play E takes D for nine, takes three for 95, and 01:11.820 --> 01:13.770 black should be fine. 01:13.770 --> 01:14.880 It should be an even position. 01:14.880 --> 01:19.950 You can see that black's kind of liberated the C eight bishop and this position. 01:19.950 --> 01:25.800 Yeah it's it's interesting there are possibilities and why can't easily play for F4 because of this 01:25.800 --> 01:33.510 diagonal so yeah this is an interesting position for black if by the way 95 wasn't played in Queen E 01:33.510 --> 01:42.450 five, this is asking for trouble like a free queen e71 has Bishop E four and if rookie eight why can 01:42.450 --> 01:47.400 actually play Rook a one here and black's just really wasted time. 01:48.910 --> 01:49.300 Here. 01:49.300 --> 01:52.750 If Knight takes a Fall Knight, take four, Queen, take four. 01:52.780 --> 01:54.730 There's Bishop takes F seven check. 01:54.730 --> 01:57.070 So if King takes, there's 95 check. 01:57.250 --> 02:00.310 And if King F eight, this is just an advantage for white. 02:01.510 --> 02:03.610 And let's say black plays H six. 02:03.730 --> 02:04.900 It's a little bit too late. 02:04.900 --> 02:06.550 White's established an advantage. 02:06.550 --> 02:09.880 This protects the Queen, which means that Knight takes hare. 02:09.880 --> 02:10.960 Knight takes, Queen takes. 02:10.960 --> 02:13.690 There's actually Bishop RD for winning material. 02:14.560 --> 02:14.710 Yeah. 02:14.830 --> 02:22.360 If queen size is going to take on eons and take on C two after so let's say Bishop C seven Bishop d4 02:22.390 --> 02:26.560 this would be nice for white, but as mentioned, black doesn't have to play this city. 02:26.560 --> 02:28.330 Queen E five going for H two. 02:28.360 --> 02:29.350 It's just silly. 02:29.440 --> 02:32.350 If black player is 95, black should be in good shape. 02:32.530 --> 02:41.230 So yeah, there's an underlying tone here for free to not commit this e four And in fact this bishop 02:41.230 --> 02:45.390 doesn't actually have to be opened up on this diagonal. 02:45.400 --> 02:48.940 What about this diagonal where it could go into D two sometimes? 02:49.120 --> 02:50.230 So very interesting. 02:50.230 --> 02:58.630 E five is played here and now H three we have Bishop C seven if E four here, 95 and Black has trouble 02:58.630 --> 03:02.500 protecting E four because there's F three in this position. 03:03.850 --> 03:11.110 If Knight BD five we can take on E four like this 9c48 we can take on F six check to relieve the pressure 03:11.560 --> 03:14.500 and then Queen takes free with small advantage. 03:14.500 --> 03:18.520 So Bishop C seven was played Bishop eight two. 03:19.090 --> 03:24.100 So again, Karpov hasn't really committed his pawns and he's waiting for black to create weaknesses. 03:24.100 --> 03:27.070 H six So why H six you might wonder. 03:27.460 --> 03:34.630 Let's have an example if Rookie Eights bishop need to and let's say B six white can use the G five square. 03:34.630 --> 03:42.130 And this is actually annoying because white can now play F4 and this rook has been developed as well 03:42.130 --> 03:44.410 and this is quite dangerous for black. 03:44.500 --> 03:50.170 He takes e takes this position with rook e one queen at Rook two This is going to be better for white. 03:50.170 --> 03:51.910 So that whole Yeah. 03:51.940 --> 03:52.900 9g5 and F four. 03:52.900 --> 03:54.430 It's kind of dangerous for black. 03:54.430 --> 03:57.550 So H six is a precaution against nine G fives. 03:57.730 --> 04:01.510 We have nine H for exploiting logically G six. 04:01.510 --> 04:05.140 So 96 sometimes is an idea, but also nine F5. 04:05.140 --> 04:10.570 So 96 to win an exchange because of that bishop pin we have rookie eight. 04:11.020 --> 04:14.890 Funny enough, let's have a look at this after a five the strongest move. 04:14.890 --> 04:16.600 What do you think the strongest move is? 04:16.930 --> 04:19.480 So this is quite curious in its own right. 04:21.190 --> 04:31.630 The strongest move turns out to be 95 because 96 we haven't got an every night defending H two black 04:31.630 --> 04:36.460 has queen de sex, which is tricky because of that h to square. 04:36.940 --> 04:44.350 And as example, if light takes their fight e takes DX four so actually practicing checkmate. 04:44.350 --> 04:50.110 So it's not that clear cut to win in exchange taking hair this position. 04:50.740 --> 04:56.440 White does have an advantage but it's not as great actually as playing night at five. 04:56.620 --> 05:01.510 This is very awkward because it kind of sucks the life out of Black's possession of the night. 05:01.510 --> 05:10.330 BE 596 and this position, for example, White's got rid of Black's Bella bishop and this is just a 05:10.330 --> 05:12.640 much superior position overall. 05:12.640 --> 05:18.310 So this is another way which maybe less controversial than trying to win the exchange. 05:18.310 --> 05:22.450 So this is very interesting for whites with the bishop pair here. 05:22.450 --> 05:26.470 So this situation is very, very comfortable indeed. 05:27.550 --> 05:40.390 So yeah, So anyway, we have rook eights being played and now 95 hair 96. 05:40.780 --> 05:46.810 Again, Queen de sex is a good idea for this diagonal takes nine takes blacks actually a little bit 05:46.810 --> 05:51.260 better so 95 is important here Queen of fake. 05:51.310 --> 05:57.760 Yes Kicking the king the queen back to the first rank and now might be fine trying to suck the life 05:57.760 --> 05:58.300 out of the position. 05:58.300 --> 06:04.320 This better bishop trying to get this better bishop out of the two bishop beings is played and now a 06:04.330 --> 06:04.750 key move. 06:04.750 --> 06:06.400 Can you see what this key move is? 06:06.400 --> 06:07.180 It seems as though. 06:07.180 --> 06:08.410 Well, isn't this pointless? 06:08.410 --> 06:09.670 The knight has to go back. 06:09.670 --> 06:11.560 But Karpov has a great idea. 06:11.560 --> 06:13.330 Tactical idea in this position. 06:13.330 --> 06:15.100 Can you see what it is for 100 points? 06:19.230 --> 06:26.400 So all of this without touching the e pawn Bishop dd two with the big fat of bishop before. 06:27.360 --> 06:29.970 So a five creating weaknesses if C sex. 06:29.970 --> 06:33.420 Let's put this on the board Bishop before What is black do here? 06:33.810 --> 06:36.390 Black's going to be losing material trying to save the queen. 06:37.710 --> 06:38.820 That's horrendous. 06:39.240 --> 06:41.790 The queen is kind of otherwise checkmated. 06:42.480 --> 06:48.600 So yeah, we have a five trying to cover the B four square D takes E five. 06:49.350 --> 06:52.620 Technically nine C free is interesting. 06:52.620 --> 06:58.590 So this position with D takes and this position is a small edge, but D takes E five. 06:58.860 --> 07:00.810 We have Bishop takes e five. 07:01.500 --> 07:02.910 If rook takes e five. 07:02.910 --> 07:08.790 It seems as though white is comfortable, but black might actually be okay here. 07:09.030 --> 07:11.850 This should be an even position in theory. 07:12.330 --> 07:14.100 Nine times e five. 07:14.100 --> 07:23.070 There's this position which black has B five just in time for 94 and this actually creates a quality 07:23.070 --> 07:28.490 any other movement and White's going to be slightly better like that gives up D four but B five here 07:28.620 --> 07:30.690 seems very appropriate for equality. 07:30.690 --> 07:31.920 So it's interesting. 07:31.920 --> 07:36.660 Bishop takes, if I might be one of the more controversial choices compared to the other two. 07:36.690 --> 07:40.860 We have four and that bishop is kind of restricted now. 07:41.580 --> 07:47.520 So yes, Black is not interested in taking the nine on B five here. 07:47.520 --> 07:50.820 This wrath of the file will be too much. 07:51.420 --> 07:57.390 So Bishop eight we have the knight going back Finally Rook D and inaccuracy. 07:57.390 --> 08:01.200 But there's only a magical tactical solution. 08:01.200 --> 08:04.800 And if Black doesn't see it, Black doesn't say it's very hard to comprehend. 08:04.800 --> 08:09.750 Let's c five actually might offer black a decent game. 08:09.750 --> 08:16.050 So as example, let's say knight g free and it looks as though White's going to just push through here 08:16.050 --> 08:18.660 potentially with E four and E five. 08:18.660 --> 08:26.730 But look at this H five rook 81 then say Bishop A seven, Bishop B one and H four. 08:28.500 --> 08:33.090 And it's reaching a critical point for Black's sensitive square. 08:33.090 --> 08:36.420 So Knights H five trying to lure the knight away from H seven. 08:36.420 --> 08:43.410 But Black has this very interesting tactical idea to suppress the white position. 08:43.410 --> 08:46.080 And if B for just sacrifice a piece. 08:46.080 --> 08:47.310 This is crazy stuff. 08:47.310 --> 08:49.320 This is computer land stuff. 08:49.410 --> 08:55.530 So Knight G three hence the Queen, hence the knight h5e for Knight takes E four. 08:55.650 --> 09:02.190 And the point is, Black gets quite a lot of pawns here for the piece sacrifice. 09:02.190 --> 09:07.650 And this actually can lead to potentially a decent enough position for black. 09:08.130 --> 09:14.370 So here, for example, Bishop Ephraim and coming up with Bishop takes a three It's crazy stuff if we 09:14.370 --> 09:18.690 look at this if a four here there's rookie two that's crushing. 09:18.840 --> 09:27.570 So the point of F5 is to be able to answer rookie two with Knight and for defending G two and hitting 09:27.590 --> 09:28.320 Ito. 09:28.320 --> 09:31.560 But yeah, Bishop be free this is guaranteed four black. 09:31.560 --> 09:35.250 It seems to be a decent enough position if we look at the pawns. 09:35.490 --> 09:37.800 Yeah, it's quite a lot of pawns for the piece. 09:38.010 --> 09:39.000 So that's about even. 09:39.000 --> 09:45.120 But yeah, that's just a crazy continuation with 95 but a slight inaccuracy. 09:45.120 --> 09:52.230 And now Bishop E one which makes this bishop come alive on this diagonal. 09:52.230 --> 09:57.330 So blunting the opponent's bishop and having one's own bishop kind of do a French defense style maneuver. 09:57.330 --> 10:03.330 You know, when bad bishop and the French is like the bad bishop here is coming to a much more decent, 10:03.330 --> 10:05.730 energetic diagonal with targets. 10:06.780 --> 10:10.620 If E4 this would be premature, it seems like C five, E five. 10:10.620 --> 10:13.920 There's not fee for tactically exposing the F five Knight. 10:13.920 --> 10:17.610 So Knight takes Bishop takes out five, doesn't matter about nine, F six Check. 10:17.640 --> 10:22.170 Black can accept the structural damage here and be even that's a different ball game. 10:22.560 --> 10:26.340 So Bishop e one we have Knights H seven. 10:29.540 --> 10:30.230 So. 10:31.560 --> 10:35.110 If C five hare Bishop H four for four. 10:35.110 --> 10:36.630 It doesn't quite work. 10:37.080 --> 10:39.000 There's 9hh6 check. 10:39.000 --> 10:45.870 So desperado before taking on E four and then this possession there's 9f6 check picking up F five bishop 10:45.870 --> 10:47.490 soon so that's crushing. 10:47.490 --> 10:56.640 So night h7h4 So this is a nice move, but also e four here is decent enough just to push through with 10:56.640 --> 11:08.730 E five and this is a nice advantage for white, but Bishop H four is decent df6 look 81 here 94 is interesting 11:08.730 --> 11:16.400 and this position white stands very nicely after Bishop B one but rook 81 black plays, rook takes D 11:16.410 --> 11:17.250 one rook takes the one. 11:17.250 --> 11:21.450 And here's the really big mistake of the game match. 11:21.750 --> 11:27.000 It does seem as though this accelerates Black's demise here. 11:28.560 --> 11:31.050 Black played Bishop Essex. 11:31.050 --> 11:32.130 Now why is this a mistake? 11:32.130 --> 11:36.150 This is really interesting from the point of view of king safety and tactics, actually. 11:36.570 --> 11:40.500 So even if you're a brilliant tactician, this is you know, it's a bit tricky what Karpov played. 11:41.100 --> 11:44.040 But let's have a look at Bishop takes that five first. 11:44.040 --> 11:49.710 This seems counterintuitive to give up the bishop, but it might have been the way to go after Bishop 11:49.710 --> 11:57.360 A seven, Bishop f2b5 White does have a small edge, so this position is a small edge, especially with 11:57.630 --> 12:01.560 the referee keeping the tension on the defile. 12:01.560 --> 12:12.160 That's an important move here to nurture a small advantage and say Black play's king h h here rook takes, 12:12.330 --> 12:12.940 queen takes. 12:12.960 --> 12:14.520 We have Bishop takes F seven 12:17.130 --> 12:19.830 and this is working as black's got a weak back row. 12:20.220 --> 12:24.660 Black can't go and win material because of Quincy ain't coming later And that's working. 12:24.660 --> 12:29.190 And if Rook takes the free, this position is nurturing small edge for white. 12:30.000 --> 12:32.310 So that wouldn't be that bad for white. 12:32.580 --> 12:35.220 So but Bishop takes five is the way to go. 12:35.220 --> 12:40.740 So this situation, if for example King H to that speculative 90 for this position, black can actually 12:40.740 --> 12:41.700 be equal. 12:41.700 --> 12:45.900 If white just goes for the double pawns, it's not such a big deal that should be equal. 12:45.900 --> 12:51.240 So why it has to tread carefully on Bishop takes South five, but with Bishop E six, a really interesting 12:51.270 --> 12:56.490 tactical solution emerges here and it's a lot of forcing moves. 12:56.490 --> 13:02.250 Bishop takes e six for takes and guess what is really strong in this position and why? 13:02.670 --> 13:04.140 Why is it really strong? 13:04.410 --> 13:09.180 I mean, there's a weakness about this that actually Black's weakened that second rank. 13:09.840 --> 13:14.010 The King Shelter G seven is under greater scrutiny potentially. 13:14.100 --> 13:15.780 So that's a clue here. 13:15.780 --> 13:18.570 But White starts off with 410 points. 13:18.570 --> 13:19.860 What does White start off with? 13:21.680 --> 13:21.900 Yeah. 13:21.920 --> 13:22.770 Queen bee free. 13:22.790 --> 13:26.660 It's like a double attack on E six and B seven. 13:26.660 --> 13:29.260 And that's the non-protected piece on eight. 13:32.070 --> 13:37.770 In fact, there was another solution here takes h six check as well with Queen G six check. 13:37.920 --> 13:46.470 This is unfortunate for the h9f8 Queen tax f six is a big advantage for Y, but this is another great 13:46.470 --> 13:46.830 solution. 13:46.830 --> 13:51.470 Queen Bee three We have Queen eight and it's a kind of weakness of the last move here. 13:51.480 --> 14:00.420 So that's compounded this second rank access which already existed and it means something here quite 14:00.420 --> 14:01.380 significant. 14:03.850 --> 14:10.270 If Bishop C-7 had been played instead, then Queen 66 is pretty noncontroversial, just taking out that 14:10.270 --> 14:10.890 E six point. 14:10.900 --> 14:15.130 If Queen F seven wrote the check and here 96. 14:15.610 --> 14:17.980 This position is winning material. 14:17.980 --> 14:24.590 But what else does black do if Queen e796b7 is just winning material. 14:24.610 --> 14:25.720 Winning that key pawn. 14:25.720 --> 14:27.430 So Queen eight was tried. 14:27.820 --> 14:33.610 Now here there is actually more than one tactical solution of the Queen eight. 14:34.360 --> 14:39.520 Now Karpov is playing a very attractive one, simple looking nine times G seven. 14:40.540 --> 14:43.570 Now, for the record, there is actually Queen Bee seven. 14:44.890 --> 14:48.640 So you might have thought, well, it takes gives black E free. 14:48.640 --> 14:49.750 Is that a big deal, though? 14:49.750 --> 14:55.150 If we take on eight Queen takes E free check, we have Bishop F two and the Queen has to scurry back 14:55.150 --> 14:57.960 for the bishop and we pick up another pawn. 14:57.970 --> 14:59.170 It's clearly winning. 14:59.290 --> 15:01.210 So Queen takes B seven. 15:01.210 --> 15:03.280 The concern is Rook seven. 15:03.280 --> 15:09.070 But we do have a move here because this x ray defends G seven, but we actually do have a move here 15:09.070 --> 15:09.580 technically. 15:09.580 --> 15:10.750 Can you see what that is? 15:12.400 --> 15:13.210 Ten points. 15:14.150 --> 15:14.590 Yeah. 15:15.370 --> 15:18.970 Queen Bee six actually frightens Rook the eight. 15:19.420 --> 15:26.680 So e thinks we're going to play rugby eight And given that's the case of 97, we can get back with Queen 15:26.680 --> 15:28.840 Bee free and we've done a bit of damage. 15:28.840 --> 15:32.380 We can maintain that pin on E six and we're just better here. 15:32.380 --> 15:39.040 So yeah, it's, it's a much superior position where tactics flow here that either nine takes G seven 15:39.040 --> 15:40.390 or Queen takes B seven. 15:40.390 --> 15:43.240 They're actually both doing a good job there. 15:43.240 --> 15:49.300 And actually we can even also consider Bishop takes F six first and then 9g7. 15:49.300 --> 15:52.900 It's just a position where tactics really flow here. 15:53.500 --> 15:56.140 So yes, it's it's a very, very difficult position. 15:56.140 --> 16:02.110 This but note takes G seven is Karpov's choice here, which is very neat as well and very simple looking 16:02.110 --> 16:03.100 in many ways. 16:03.100 --> 16:04.540 So so game on. 16:04.540 --> 16:12.790 Black played Queen seven if King takes the point is Queen takes B seven check and then picking up the 16:12.790 --> 16:17.230 rook and notes know the queen's like locked in still it's not out and about. 16:18.610 --> 16:24.340 And if we look at this if bishops C seven yeah, we're just going to take on C seven, take on C six. 16:24.340 --> 16:25.270 Thanks very much. 16:25.270 --> 16:32.170 So Queen seven and now we have 966 winning another pawn. 16:32.170 --> 16:38.710 So it's two pawns up Bishop a seven, Bishop F two defending a free why not rookie eight and now 94 16:38.710 --> 16:44.320 so that rescues of the Knights and the Queen is protected by the knight here. 16:44.320 --> 16:47.470 So Queen takes be free if Bishop takes DD four. 16:47.470 --> 16:50.590 Yeah we're just going to take on F seven and then say it on D four. 16:50.590 --> 16:51.310 Thanks very much. 16:51.310 --> 16:52.630 Two pawns up. 16:52.870 --> 16:53.560 So, Queen. 16:53.560 --> 16:53.830 Thanks. 16:53.860 --> 16:54.730 Be free, Knight. 16:54.730 --> 16:55.000 Thanks. 16:55.000 --> 16:55.780 Be free. 16:56.440 --> 17:01.960 And it doesn't matter here about EA free dropping because why it's taking there and then taking on a 17:01.960 --> 17:08.590 five and this ends the game here move for two quite short game so if rook e seven. 17:08.590 --> 17:08.720 Yeah. 17:08.740 --> 17:08.890 Why? 17:08.890 --> 17:10.360 It's just two pawns up here. 17:10.360 --> 17:16.630 This is pretty much this level over and white can start improving the position soon with 95 to bring 17:16.630 --> 17:17.860 the rook back if needed. 17:17.980 --> 17:23.980 And it's just two pawns up so, you know, can't come up with one that pretty quickly against Vishy 17:23.980 --> 17:24.280 Anand. 17:24.280 --> 17:27.670 So like takes a five the final possession. 17:28.510 --> 17:30.070 So a very, very interesting game. 17:30.070 --> 17:35.950 The way the opening was played in actually is really inspiring because this is actually quite a dangerous 17:35.950 --> 17:43.000 variation when E4 is played in E5, Black does seem to get a lot of peace activity, so the way Karpov 17:43.000 --> 17:49.090 played it was with minimal risk, minimal counterplay and using interesting diagonals for his C one 17:49.090 --> 17:50.500 bishop in this game. 17:50.500 --> 17:53.890 So the C one bishop was really, really interesting. 17:53.910 --> 18:01.510 I was kept at bay and then tactically used in a little combination here with Knight B five for Bishop 18:01.510 --> 18:02.320 D two. 18:02.320 --> 18:04.240 Absolutely fascinating game. 18:04.240 --> 18:10.570 How this seemingly passive structure offers so many opportunities in different ways. 18:10.570 --> 18:13.000 After this E five is played. 18:13.000 --> 18:14.890 Really, really fascinating game. 18:14.890 --> 18:18.490 I hope you enjoyed this one as much as me and so much.
