WEBVTT 00:01.770 --> 00:02.590 Hi there. 00:02.610 --> 00:06.410 In this lecture, we see Anatoly Karpov playing against Raphael, the Ghanaian. 00:06.420 --> 00:08.280 This is 1976. 00:08.290 --> 00:14.670 Scobey torments around one, so E four from Karpov E six We have default D five. 00:14.670 --> 00:19.080 So the Ghanian is a French defense expert, all major exponents. 00:19.080 --> 00:22.250 So we see 92 from Karpov. 00:22.260 --> 00:28.500 So this is the tarrasch variation and quite often it can lead to an isolated Queen's pawn situation. 00:28.650 --> 00:33.660 So here after E takes E takes, we have a potential for an isolated Queen's pawn. 00:33.780 --> 00:35.760 As soon as white plays D take C five. 00:35.760 --> 00:40.020 But why is waiting here for the bishop to move first? 00:40.560 --> 00:49.290 A six is played there now, but here, instead of waiting further, why actually does commit to D take 00:49.320 --> 00:52.110 C five even though it seems to give a tempo. 00:52.440 --> 00:54.240 So this is an interesting situation. 00:54.240 --> 00:57.690 The thing is there is might be free gaining a tempo. 00:58.110 --> 00:59.910 Bishop B6 and now Bishop de fray. 00:59.910 --> 01:09.540 So what has a comfortable position at the opening 97 white castles like BC six rookie one and this isn't 01:09.540 --> 01:14.660 this is isn't just about the E fold this is about a strategic bishop exchange. 01:14.670 --> 01:20.910 If we can remove the dark square bishops, then the default blockade square is further amplified. 01:21.180 --> 01:27.000 Bishop G four We have C free h6h free Bishop H five and our Bishop E three. 01:27.010 --> 01:32.490 So this important strategic Bishop exchange tries to nullify the dynamic aspects of the position. 01:32.490 --> 01:36.990 The F two The King safety needs to be nullified to be safer. 01:36.990 --> 01:41.790 And getting rid of that dance quo, Bishop say, makes the king safer. 01:41.790 --> 01:43.920 But also the blockade square a bit cozier. 01:44.220 --> 01:51.930 We have Queen E to rook 58, Rook 81, and now a five, and now Bishop B one. 01:52.080 --> 01:58.460 There are tactics to consider in this position because Black's threats things, sometimes it seems to 01:58.470 --> 01:59.520 potentially win a pawn. 01:59.520 --> 02:01.110 So tactical considerations. 02:01.130 --> 02:05.130 If the Queen's not protecting B two, isn't this dangerous? 02:05.130 --> 02:09.360 Well, one could question that there is another move here Instead of Bishop B one, there is actually 02:09.360 --> 02:14.970 G four, but this might only lead to an equal position if the Queen's are challenged. 02:14.970 --> 02:17.010 The Black could keep the Queen's on. 02:17.010 --> 02:22.980 This position is just even anyway, So Bishop B one is played and now Bishop takes a three, which is 02:22.980 --> 02:26.190 actually it's tempting, but it's a mistake. 02:26.190 --> 02:29.460 It's compromising black on the light squares. 02:29.580 --> 02:35.580 So the instructive thing about this game, it's not all about the isolated Queen's pawn now. 02:35.970 --> 02:38.880 It's quite a lot about this bishop, our counterpart. 02:38.880 --> 02:44.610 In fact, there is an attacking perspective around this structure, even though you'd think usually 02:44.850 --> 02:47.760 the attacking player is the one that's taking the risk with the pawns. 02:47.760 --> 02:51.120 Russia kind of sacrificed pawn structure for peace activity. 02:51.120 --> 02:58.800 But here why is really good on the light squares and we see a four and the idea of black to win this 02:58.800 --> 02:59.940 pawn on B two. 02:59.970 --> 03:06.690 However now the forcing move might take six so the knight has to take on C six and now we get light 03:06.690 --> 03:13.860 squared pressure Queen F five inviting will kind of encouraging dark square weaknesses, otherwise black's 03:13.860 --> 03:14.940 going to get mated. 03:15.060 --> 03:18.450 So we see this is a very interesting situation. 03:18.450 --> 03:25.950 But also here, perhaps even more accurate in this position is to play h four. 03:27.410 --> 03:31.070 Because this has ideas of playing queen differ in age five. 03:31.070 --> 03:39.500 So as example, if Rook dd six queen dd free black does best it seems well any rook g six there's H 03:39.500 --> 03:41.510 five so let's say g6h5. 03:41.510 --> 03:44.060 This is difficult for black, this position. 03:44.060 --> 03:46.250 All of a sudden it's become about attack. 03:46.730 --> 03:55.280 So after F takes, because if Rook takes, then that kind of fragments black structure here and this 03:55.280 --> 04:00.620 situation with Queen a free is just going to be very favorable for white taking out D five and then 04:00.620 --> 04:03.920 later to take out H six it's going to be extremely favorable. 04:03.920 --> 04:06.530 So let's imagine F takes g six instead. 04:07.520 --> 04:11.690 Rookie two, Queen free, Queen G free six. 04:11.900 --> 04:14.390 This position white's just better. 04:14.570 --> 04:16.880 That is another legitimate way of playing it. 04:16.880 --> 04:19.300 H four here it seems better. 04:19.460 --> 04:22.520 Yeah, we have Queen f5g6. 04:22.850 --> 04:23.810 Queen F six. 04:23.810 --> 04:27.020 So this protects C free. 04:27.410 --> 04:31.700 But also there's another very interesting idea here. 04:32.810 --> 04:37.250 Well, there's an idea of sacrificing on G six Black tries to make provision for that with rook these 04:37.250 --> 04:41.990 seven if rook e eight bishop takes g six is strong. 04:41.990 --> 04:49.190 This is just attacking chess here because the queen can mop up the pawns and then the rook comes in 04:49.190 --> 04:51.890 for the kill here or winning the queen. 04:51.890 --> 04:58.220 So Rook D seven was tried, but now there's a shocking tactical move from Karpov. 04:58.610 --> 05:02.390 So yes, very aware of the concrete stuff of positions. 05:02.480 --> 05:06.410 So in this, in this position, what would you play for 100 points? 05:09.610 --> 05:10.330 A forcing move. 05:10.380 --> 05:11.360 Bishop at five. 05:11.430 --> 05:11.830 Yeah. 05:12.880 --> 05:13.720 This is very interesting. 05:13.720 --> 05:20.230 If rook free, there is d44 black to play and this possession black should be just about OC. 05:20.530 --> 05:28.450 For example, here it should be about even so oc Bishop F five though, is the move. 05:28.930 --> 05:29.230 Yeah. 05:29.230 --> 05:30.720 This is a very, very interesting move, Bishop. 05:30.730 --> 05:33.210 At five we have rook e seven. 05:33.220 --> 05:37.630 Funny enough, if it was taken rook D three does seem very strong. 05:37.630 --> 05:42.220 There's four the Queen could take and it seems as though y it's got a very strong attack for the piece. 05:42.400 --> 05:48.350 But there is one move which might save black f six is the only move, in fact, which seems to save 05:48.350 --> 05:54.940 black because it facilitates rook g seven and here White just has perpetual check scenarios or potential 05:54.940 --> 05:56.920 attack scenarios for a draw. 05:57.310 --> 06:01.420 So it seems yeah, that would have been perhaps a better idea. 06:01.450 --> 06:02.650 G takes her five. 06:02.680 --> 06:07.060 If Rook D we see Bishop G six again and this is a strong attack. 06:07.060 --> 06:08.680 The Queen and the rook. 06:08.680 --> 06:10.240 Very, very strong force here. 06:11.350 --> 06:18.670 So Rook E seven was played and we have rook takes e seven knights, 87 Bishop drops back, and there's 06:18.670 --> 06:20.230 the potential now to do a lot of damage. 06:20.230 --> 06:27.340 So five Bishop takes F five and you can see all of a sudden look at the structural wreck, train wreck 06:27.340 --> 06:28.560 of Black's position. 06:28.570 --> 06:37.210 Structurally we have rook e one so ideas of either rook lifts or rook E seven we have queen takes a 06:37.240 --> 06:44.770 two, queen takes h6a free queen g five check king of fake queen F six. 06:45.790 --> 06:54.520 So this threatens to play potentially queen air can pick the rook up King Queen takes a five queen rd 06:54.520 --> 07:02.610 to rook e seven is used so rook eight queen G four check King H seven and now rook E five. 07:02.620 --> 07:04.600 So a little mermaid pattern. 07:05.080 --> 07:08.800 So, blimey, is this a position, of course, or an attacking course? 07:08.800 --> 07:14.170 Well, the thing is, I think it's important to show that when playing against the isolated Queen's 07:14.170 --> 07:17.740 pawn, it's not all about the pawn structure sometimes. 07:17.740 --> 07:20.320 Sometimes it is about other dynamic aspects. 07:20.320 --> 07:23.440 So here, Queen H six, Rook five. 07:23.830 --> 07:26.200 And yeah, Black's really kind of had it. 07:26.200 --> 07:28.990 The pawn isn't enough here. 07:28.990 --> 07:34.750 So Queen at five, King G seven Rook takes H six King takes a six. 07:35.080 --> 07:41.140 Queen of six check King eight, seven Queen takes F seven check cash eights and now Queen takes B seven 07:41.140 --> 07:42.220 ends the game. 07:42.730 --> 07:49.600 If rook a five, then Queen C and Queen C seven will pick up the rook. 07:50.020 --> 07:55.030 If rook a four, then Queen c H, Queen D seven champ will pick up the rook. 07:55.030 --> 07:57.250 Yes, it's a hopeless position in the end. 07:57.250 --> 08:02.650 So a very interesting kind of dynamic treatment against the isolated Queen's pawn. 08:02.650 --> 08:06.940 So a positional kind of variation, it seems again, structure. 08:06.940 --> 08:11.200 And because of the tempo gaining aspect of might be free. 08:11.680 --> 08:18.430 What didn't really wait any longer, didn't see the need to wait any longer here so interesting. 08:18.430 --> 08:24.550 So D takes this might be free Bishop D free so key points positioning against the Queen's pawn. 08:24.640 --> 08:28.180 Take out the Dart square campaign of black. 08:28.180 --> 08:36.550 Try and exchange off Dart Square bishops, reinforce the blockade square d four and if black plays actively 08:36.550 --> 08:40.570 against B two, there are other aspects in the position here. 08:40.570 --> 08:45.940 King Safety with the knight on E seven rather than six means that this diagonal maybe is a bit more 08:45.940 --> 08:49.960 dangerous than usual, especially the H seven is a softer spot than usual. 08:49.960 --> 08:57.670 So this position is a very interesting basically kind of gambit for a strong attack potential here after 08:57.670 --> 09:03.400 nine, 8c6 and queen of five, how the weaknesses are encouraged and then the threats imminent. 09:03.400 --> 09:06.400 But Bishop at five is a very, very good try. 09:06.430 --> 09:10.420 So black goes wrong and actually gets a lost position. 09:10.420 --> 09:13.630 Soon after rookie seven black had to take on five. 09:13.630 --> 09:15.460 So a very, very interesting game. 09:15.940 --> 09:22.090 Is it positional is it attacking well that there's a blur there's this fine blurred distinction So sometimes 09:22.090 --> 09:29.140 in this course we will see attacking games but there is a positional undertone to this attack So here 09:29.140 --> 09:31.570 yeah the pawns getting mopped up. 09:32.080 --> 09:33.940 It's a very, very dangerous scenario. 09:35.350 --> 09:38.230 So yeah, crushing attack in the end. 09:38.350 --> 09:45.760 And if at five by the way there's rook E seven check and that will be mating pretty soon after. 09:46.000 --> 09:47.320 So yeah. 09:47.320 --> 09:50.440 This is just an absolute last position now so. 09:50.440 --> 09:52.090 Och interesting game. 09:52.090 --> 09:53.440 I hope you enjoyed this one. 09:54.250 --> 09:57.880 And the game ended on Queen B seven has so much.
