WEBVTT 00:00.900 --> 00:01.660 Hi there. 00:01.680 --> 00:07.270 In this lecture, we see Boris Gelfand playing against Anatoly Karpov in the installments of 1994. 00:07.290 --> 00:11.240 So this was one of complex greatest tournaments ever. 00:11.250 --> 00:15.120 So it's interesting to see with the black pieces how he played so E4. 00:16.110 --> 00:20.040 We have a common icon after D 45 E tank. 00:20.070 --> 00:20.680 C tanks. 00:20.700 --> 00:23.430 c49569c36. 00:23.430 --> 00:28.560 We actually transpose into a variation of the Nims Indian hair of the Bishop b4. 00:29.670 --> 00:35.700 So that's very interesting because Karpov and Adams, Michael Adams, they're both fans of names of 00:35.700 --> 00:38.520 Engine Queens and Positions and the Kraken. 00:38.520 --> 00:41.680 So it's interesting to try and leverage opening knowledge. 00:41.700 --> 00:46.350 So here we have Bishop de Fray and now D take C4. 00:46.350 --> 00:47.730 Bishop take C4. 00:48.630 --> 00:57.570 So one is given the Queen's pawn, black castles, white castles, and now Karpov plays B six, so he's 00:57.570 --> 01:00.750 intent on trying to get authority on the light squares. 01:00.750 --> 01:07.050 It looks very logical and if necessary, to give up the dark square bishop to try and amplify the light 01:07.050 --> 01:08.240 square grip. 01:08.250 --> 01:15.150 We have Bishop G five, Bishop B seven, Rookie one and now volunteering the Dart Square, Bishop gives 01:15.150 --> 01:17.010 White a backward pawn. 01:17.460 --> 01:24.180 But chess is not just about pawns, especially if the opponent has strong attacking pressure. 01:24.360 --> 01:28.230 One has to be very careful here to be objective. 01:28.230 --> 01:34.830 Like BD seven we have Bishop DD Free Queen C seven, Rook C one and now Queen dd six. 01:34.830 --> 01:40.260 So this is interesting to try and be annoying with the use of the a free square, which was a kind of 01:40.260 --> 01:41.970 weakness of a capture there. 01:41.970 --> 01:43.800 The four is available to black. 01:43.830 --> 01:45.120 Is it that useful though? 01:45.120 --> 01:52.500 We have Bishop H four Rook f.c eight Bishop G free and the Queen does park for the moment on a free 01:53.400 --> 01:59.790 where else if Queen E seven that's going to run into C four for D five with the rook X-raying the Queen. 01:59.790 --> 02:03.120 So this doesn't look too clever, this situation. 02:03.390 --> 02:10.860 So for example here, in fact, also this pin could be annoying and White's getting overall a nice advantage 02:10.860 --> 02:11.010 here. 02:11.010 --> 02:12.510 So queen a free for the moment. 02:12.540 --> 02:13.590 C for now. 02:13.590 --> 02:14.610 Knight F eight. 02:15.820 --> 02:19.570 It's quite dangerous to take the pawn here as example. 02:19.590 --> 02:26.070 Bishop DD six is making an effort to try and trap the Queen, taking out the a free square if Queen 02:26.070 --> 02:30.420 5d5 we can see here maybe 95 is one of the better moves. 02:30.420 --> 02:39.870 But rook one and the queen is being harassed here and it's difficult to get back into a safe position. 02:39.870 --> 02:45.690 So here, for example, Bishop E5 harasses the Queen and then Queen D four. 02:46.320 --> 02:53.580 And we can see this could be a scenario which is very favorable to white, building up more pressure 02:53.700 --> 02:56.400 and being able to take out G seven sometimes. 02:56.400 --> 02:58.650 Yeah, the Queen's subject to a lot of harassment. 02:58.650 --> 03:00.180 So Queen takes a two. 03:00.180 --> 03:02.430 Does seem too complex. 03:02.940 --> 03:07.140 So Knight F ain't trying to reinforce the soft spot. 03:07.140 --> 03:09.990 H seven We have 95 and now nine. 03:09.990 --> 03:10.770 G six. 03:10.980 --> 03:16.320 So one of the things Karpov wants to do, he ideally like this, like square bishop to go. 03:16.560 --> 03:19.290 We have rookie free if the Knight Square bishop goes. 03:21.080 --> 03:22.160 Or there's an exchange. 03:22.160 --> 03:23.990 This helps black considerably. 03:23.990 --> 03:28.750 This position is only a small edge for white, and this position is only a small edge. 03:28.760 --> 03:31.820 The simplification would really be helpful for black. 03:32.870 --> 03:38.870 So yeah, rookie free is interesting because it now threatens Bishop takes G6 hitting the Queen. 03:40.040 --> 03:47.300 Another option here H four does seem dangerous to try and harass this night with tempo. 03:47.300 --> 03:54.980 So as example, if Queen E seven in fact H five is not even needed here G four and here D five. 03:54.980 --> 04:00.320 This position you can see why it should have some attacking prospects in this position. 04:00.320 --> 04:02.090 Chess is not that simple. 04:02.540 --> 04:07.280 And yeah, white does have sufficient counterplay. 04:08.090 --> 04:10.670 This doesn't have to be a one way game at all. 04:10.670 --> 04:17.840 White's doing quite well here with a nice attacking position, so H4 does seem a key to the position 04:17.840 --> 04:19.460 for White, which was missed. 04:19.460 --> 04:21.890 So rookie free was played. 04:22.070 --> 04:29.000 We have Queen for an F4 and this is definitely not a great way to attack it does leave weaknesses behind 04:29.000 --> 04:34.640 that diagonal of def it seems all the world champions well especially like Fischer Kasparov. 04:34.820 --> 04:40.010 If there's such a weakness on the diagonal they'll find a way to make use of that to exploit that. 04:40.010 --> 04:44.450 Somehow it seems H four is much more dangerous. 04:44.450 --> 04:53.900 So for example, 90 7h5 and in fact one could try and undermine black on the dark squares this position. 04:53.900 --> 04:58.670 Bishop h495d5 is very, very dangerous. 04:58.670 --> 05:05.390 There's a lot of dynamics which are occurring here and yeah, it's just this form pawn, this pressure 05:05.390 --> 05:06.440 on the diagonal. 05:06.620 --> 05:12.770 If we look at this just with another sample example, Knight takes a five, Bishop takes e five here, 05:12.800 --> 05:19.310 Bishop takes H seven check shows why it could potentially conjure up a strong attack with a double bishop 05:19.310 --> 05:21.890 sacrifice, for example, like this winning the Queen. 05:21.890 --> 05:24.020 Otherwise the black king is going to get mated. 05:25.310 --> 05:26.050 You know this. 05:26.060 --> 05:28.940 This doesn't look too promising with black king get made. 05:28.940 --> 05:31.370 So these scenarios are dangerous. 05:31.370 --> 05:38.750 They are very dangerous for black, but white has to play to try and maximize peace harmony throughout 05:38.750 --> 05:39.350 the attack. 05:39.350 --> 05:41.720 H4 does that because it doesn't close up. 05:41.720 --> 05:43.010 The bishop doesn't weaken the diagonal. 05:43.010 --> 05:47.000 It doesn't create so many downsides as what was played, which is F4. 05:47.780 --> 05:53.030 So there's a potential lack of harmony in White's position here with this pawn. 05:53.030 --> 05:56.120 If it's locked, if it's dissuaded from F5. 05:56.210 --> 06:00.290 So aims first to take Target at D four. 06:00.680 --> 06:03.800 So this is prompting a defense for D four. 06:03.800 --> 06:06.320 We have Bishop B one and now 97. 06:06.320 --> 06:09.410 So F five is prevented or discouraged. 06:09.560 --> 06:13.940 Bishop h4 now nine, G six, Bishop G five. 06:14.360 --> 06:22.910 And now an interesting way of trying to get counterplay with Black B five here and underline the line 06:22.910 --> 06:24.410 square weaknesses of White's position. 06:24.410 --> 06:25.910 These pawns are not squares. 06:25.910 --> 06:28.730 The adjacent light square weaknesses are interesting. 06:29.570 --> 06:39.800 If H six bishop takes g six is annoying, this position will be annoying for black if rook c seven then 06:39.800 --> 06:41.060 here rook g. 06:41.070 --> 06:48.740 For this position H will could still come to the rescue somewhat with a decent enough position for white. 06:48.740 --> 06:53.990 Actually, if we take this a bit further using the pin there about Queen D free looking at age seven, 06:53.990 --> 06:57.320 it starts to get a little bit dangerous with resources. 06:57.320 --> 07:00.290 You know, there's attacking resources chances are complex game. 07:00.290 --> 07:08.180 So this this way White's going to get a potentially really interesting position here with attack potential 07:08.810 --> 07:16.610 even if D four drops this looks like an attack versus positional play and for example here once doing 07:16.610 --> 07:17.300 quite well. 07:17.300 --> 07:24.560 So this is all pretty fictional based on H six, but B five is played and now if there's a clear possession 07:24.560 --> 07:29.120 or mistake while conducting the attack, it's this one, it seems Bishop takes G six. 07:29.120 --> 07:32.150 That was one of the better pieces in White's position. 07:32.390 --> 07:35.510 C five is more interesting. 07:35.510 --> 07:38.030 So for example here, just keep the line square. 07:38.030 --> 07:39.800 Bishop It's nice. 07:39.950 --> 07:44.120 And if this position d5e takes Bishop F five, it's useful. 07:44.300 --> 07:50.990 It can be a hero here with Bishop F5, as example, winning the exchange and when it's going to be better. 07:50.990 --> 07:55.730 So with that Bishop giving up, that bishop seems to be a bit of a tragic positional mistake. 07:56.000 --> 07:58.790 And after this H takes g rook free. 07:58.790 --> 08:04.250 It seems White is playing in a very crude manner, trying potentially if White gets the chance. 08:04.400 --> 08:09.170 It hasn't got a chance just yet, it seems, for this kind of construction, which would be very dangerous. 08:09.680 --> 08:14.420 So Rook c7d5 if Queenie won. 08:14.420 --> 08:18.200 The thing is, it's far too slow after Queen takes the four check. 08:19.610 --> 08:25.580 When we see 94 to the rescue And yeah, classic check will be winning everything. 08:25.850 --> 08:32.530 So we have the five trying to shut down Black's use of D four, but at what cost. 08:32.540 --> 08:34.070 So C five. 08:34.100 --> 08:35.660 This is a bit of a vulnerable pawn. 08:35.660 --> 08:42.590 Now, Bishop C eight is not taking too much risk with king safety with Bishop C A as example, a slow 08:42.590 --> 08:49.370 move and black's going to be obliterated with Queeny 12h4 It will be too late to plan this because of 08:49.370 --> 08:59.000 g four if Queen Queen H four and we can see some of the dangers here that this position is is not very 08:59.000 --> 09:00.230 good for black at all. 09:00.230 --> 09:06.170 Yeah, the crude crudeness is actually paying off here, but with Bishop K immediately it's difficult 09:06.170 --> 09:07.070 for white. 09:07.400 --> 09:08.600 That was just the token move. 09:08.600 --> 09:11.750 I just wanted to show you what one is actually threatening. 09:13.910 --> 09:23.360 So basically we've bishop see a rook be free is played evicting the attacking piece of G for queen E 09:23.360 --> 09:24.980 aids and here. 09:26.790 --> 09:29.820 In this position that's I'm pinning the nine and looking at g four. 09:29.820 --> 09:36.660 So if Queeny one we just take on G four and there's enough defensive resources here. 09:38.550 --> 09:46.320 So if nine takes nine, if nine takes G four, there's Queen takes E one check and 9g4. 09:46.320 --> 09:47.610 Black's doing very well. 09:47.610 --> 09:49.050 So rook be free. 09:49.470 --> 09:56.580 We have Queenie eight protecting B five Also Bishop at five was already good four black hair with rook 09:56.580 --> 10:05.310 a.k.a this possession queen e six taking the opportunities for a past d pawn here and a nice bishop. 10:05.310 --> 10:07.740 This is just very nice for black overall. 10:07.740 --> 10:14.090 So Queen eight we have Queen D for Bishop and five rook e three and now queen for eight. 10:14.100 --> 10:15.990 So a lot of queen moves from Karpov off that. 10:15.990 --> 10:18.360 They are very well designed. 10:18.360 --> 10:19.890 We have Bishop takes f6. 10:19.890 --> 10:23.100 This is a mistake it seems C six. 10:23.100 --> 10:32.430 This position should still be almost in balance with pressure on D five and that passed pawn but with 10:32.430 --> 10:35.550 Bishop takes F six, G takes a free. 10:36.180 --> 10:43.890 We have Bishop E four, King G seven who also go in this position is nice for black. 10:44.190 --> 10:49.290 So Bishop E four we have 92 and F five rook ac three. 10:49.320 --> 10:54.660 If Knight takes E four, D takes Black has a big advantage here, it seems. 10:54.660 --> 11:02.220 You know, this position is unfortunate for white for example here rook d one shank and then we take 11:02.220 --> 11:03.450 out C five. 11:03.450 --> 11:05.610 That's got a very strong position. 11:06.090 --> 11:14.880 So rook ec three we have a five, C six and now Queen b4 maybe even slightly better is Queen G seven. 11:14.880 --> 11:22.530 So this situation is fairly pleasant for black as example with D for the rook endings here are in black's 11:22.530 --> 11:23.250 favor. 11:23.640 --> 11:25.500 This position is in black's favor. 11:25.500 --> 11:26.700 F fours weak. 11:26.700 --> 11:28.200 That's in Black's favor. 11:28.200 --> 11:30.000 So Queen before though was played. 11:30.000 --> 11:31.230 We have Knight be free. 11:32.040 --> 11:34.680 If Queen takes b4, then 8/8. 11:34.680 --> 11:38.510 And that's cop off's intention to take out a two hair. 11:38.520 --> 11:47.300 And this scenario with Rook A6 is very difficult rook component and that's got a big past pawn on E4 11:47.340 --> 11:57.060 big advantage so might be very we have queen dd sex queen F to better here Mervyn rockets raids go for 11:57.060 --> 12:04.890 it with rook H three is threatening rook A and Queen H a mate and if f6. 12:07.300 --> 12:08.500 Then Queen F2. 12:08.530 --> 12:11.830 This crude idea might actually be the only way to go here. 12:11.860 --> 12:21.520 Giving up C six this possession with Queen H for there is check and here queen A seven protected by 12:21.520 --> 12:22.210 the queen. 12:22.210 --> 12:25.080 But this doesn't look too clever. 12:25.090 --> 12:30.550 White can take on f six this possession and has at least a perpetual check. 12:31.120 --> 12:34.840 So this is any Queen seven this eight check. 12:34.840 --> 12:37.000 So this would just be a perpetual check. 12:37.180 --> 12:38.740 So that was the way to go. 12:38.740 --> 12:39.870 It seems real cage free. 12:39.880 --> 12:41.160 Just go for it here. 12:41.350 --> 12:49.000 But Queen F two was played instead and now b4c5. 12:49.030 --> 12:52.240 If rook free here, it seems far too slow. 12:52.240 --> 13:02.800 Rook S.C six And for example Queen h4c1 check 9c1 Black leverages that diagonal with Quincy one check 13:02.800 --> 13:05.170 and it's White's king that's in big trouble. 13:05.170 --> 13:07.420 This would open up the for tempo. 13:07.600 --> 13:12.370 So this position is just going to be all over for White's king, for example. 13:12.370 --> 13:14.740 Like this is mating. 13:14.890 --> 13:24.100 So Rook five White's attack is attacking James have disappeared now a 494 and now Bishop D three. 13:24.100 --> 13:29.500 And what White is left with is the prospect of a stranded rook after Bishop C four. 13:29.680 --> 13:33.430 So yes, a lot of resources are being tied up behind this pawn. 13:34.000 --> 13:40.690 A bit of a downside of a possible Now if you overdo it with the resources tied up with that pawn. 13:40.810 --> 13:48.010 So here queenly two if h raid is to show Bishop c four with the Queen c54, it might be five. 13:48.010 --> 13:49.450 Sure is possible. 13:49.450 --> 13:53.230 But here this scenario is in Black's favor. 13:53.230 --> 13:58.690 Black can make progress here, for example, with a3d free. 13:59.050 --> 14:02.980 And this simplification is only going to favor black. 14:02.980 --> 14:04.900 This game is very very nice to play. 14:04.900 --> 14:07.330 So Queen D two is tried. 14:08.620 --> 14:14.470 Bishop C four stranding the rook, rescuing the rook but losing F4. 14:14.470 --> 14:19.720 So for the moment the rook is living on the day Queen C free. 14:19.720 --> 14:26.260 We have rookie but Karpov has gained this central foal now to play with Rook D one and now infiltration 14:26.260 --> 14:28.990 rookie free with tempo Queen C one. 14:28.990 --> 14:30.180 Queen E four. 14:30.310 --> 14:32.050 Why it's totally tied down now. 14:32.050 --> 14:34.390 Queen one This is looking bad. 14:34.390 --> 14:45.970 Rook eight We have Rook a five and now Rook free targeting a two queen B one queen free taking H one 14:46.210 --> 14:50.950 rook takes a two rook on the seventh rank Lots of juicy targets. 14:51.040 --> 14:53.770 Knight Free Bishop be free. 14:55.240 --> 14:57.940 We have Quincy one and now F four. 14:57.940 --> 14:58.960 Yeah, it's all over. 14:58.960 --> 14:59.470 Basically. 14:59.470 --> 15:03.820 Why it hasn't got too much play Rook C2 trying to get simplification. 15:03.820 --> 15:07.690 Queen one If rook takes EA free rook take one check. 15:07.690 --> 15:12.880 This possession is just all over Endgames A nightmare that's got a huge advantage here. 15:13.540 --> 15:18.910 So we have Queen a one, but now Queen B six just kind of wins the rook. 15:19.330 --> 15:19.880 Yeah. 15:20.920 --> 15:27.760 So this is it won't resigned if Bishop if rook takes a four losing the exchange There's no compensation 15:27.760 --> 15:28.540 for white here. 15:29.380 --> 15:29.710 Yeah. 15:29.740 --> 15:30.460 This is crushing. 15:30.460 --> 15:32.630 So Queen B six ending the game there. 15:32.650 --> 15:34.750 So a very, very interesting game. 15:35.050 --> 15:38.380 We see a little bit potentially on the defensive. 15:38.380 --> 15:44.800 What really helps Karpov are crucial moment and he does need help from opponents to pull this stuff 15:44.800 --> 15:45.370 off. 15:45.610 --> 15:51.700 It seems F4 doesn't lead to a great attack compared to H four. 15:51.700 --> 15:57.310 What has to try and get the attacking potential out of this dynamic structure with White not getting 15:57.310 --> 16:00.130 the attacking potential from the dynamic structure. 16:00.130 --> 16:07.210 It seems Karpov was starting to tie White's resources down and this B5 is very, very interesting. 16:07.280 --> 16:09.190 These situations are very, very interesting. 16:10.090 --> 16:17.350 But yeah, the defensive accuracy was needed and come off delivered here with Bishop C eight and Queen. 16:17.590 --> 16:23.770 I'm pinning useful to Unpin and yet it started to be downhill for white. 16:23.860 --> 16:30.400 A very complicated game, but fundamentally there seemed to be a lack of harmony in the conduct of the 16:30.400 --> 16:35.010 attack from White, which led to other issues as well. 16:35.020 --> 16:39.220 This protected pawn was using up too many resources which are themselves targets. 16:39.220 --> 16:43.930 So on paper you might think, well, a passport is dangerous, but if it's sufficiently blockaded, 16:43.930 --> 16:46.180 a lot of resources can be tied up behind that. 16:46.390 --> 16:51.580 But yes, Black's piece harmony for our seemed to be very good as well. 16:51.580 --> 16:52.810 Much better than whites. 16:52.810 --> 16:54.730 So yes, a crucial mistake. 16:55.030 --> 17:04.630 Let Karpov have a fantastic game fundamentally when White played this full move so that's it's not only 17:04.810 --> 17:05.980 blocks in. 17:06.600 --> 17:07.140 The dark square. 17:07.140 --> 17:15.750 Bishop This diagonal is just so good in the hands of skill players for operations with tempo and defensive 17:15.750 --> 17:17.490 operations and combinations. 17:17.650 --> 17:21.030 OC I hope you enjoyed this one so much.
