WEBVTT 00:01.470 --> 00:02.530 Hi there. 00:02.550 --> 00:09.210 In this lecture, Anatoly Karpov is playing against Boris Spassky in the 1980 plus tournament, fourth 00:09.210 --> 00:10.830 edition of the tournament Round nine. 00:10.830 --> 00:13.080 So E four from Karpov. 00:13.530 --> 00:18.000 We have C five from Boris Spassky, nine we have three from Karpov. 00:18.000 --> 00:18.810 DD four. 00:20.660 --> 00:26.150 So after the d4c tanks, 1964 of 69c3, now E six. 00:26.150 --> 00:31.880 So the shaving game variation, which does allow the carriers attack named after Paul Keres and Karpov 00:31.880 --> 00:37.430 chooses G four Here we have h6h4 90 6g1. 00:38.030 --> 00:39.470 So this is an interesting position. 00:39.470 --> 00:42.860 We have de five from black here. 00:42.860 --> 00:54.710 Bishop B five is plain, Bishop d7e taints d59 65 If E takes D five Queen E to check is going to be 00:54.710 --> 00:56.870 more interesting for white here after Bishop e three. 00:56.870 --> 01:03.230 This is actually a rather pleasant position even if simplification happens and you might think these 01:03.230 --> 01:04.070 pawns awake. 01:04.070 --> 01:07.340 It's actually rather nice for white say black castles. 01:07.340 --> 01:14.060 Queenside bishop takes D seven check Rook takes these seven this position one has nothing to fear. 01:14.060 --> 01:16.580 It's a nice blockade on the isolated Queen's pawn. 01:16.940 --> 01:18.470 Overall advantage for white. 01:18.470 --> 01:26.270 So we have Knight text five 965 E taints D five Bishop e three Bishop e seven. 01:26.270 --> 01:27.410 Queen D two. 01:27.950 --> 01:32.240 And here Boris Spassky does to take on H four. 01:33.260 --> 01:36.260 There was actually in later years after this game. 01:36.260 --> 01:43.220 And modern engine analysis also agrees that it seems in this particular position this would normally 01:43.220 --> 01:49.550 be a crazy looking move to Castle right into a ready built attack, half built attack. 01:49.550 --> 01:51.020 But it might be the way to go. 01:51.020 --> 01:57.320 As in Timman, who was a correspondence world champion against of Anderson. 01:57.770 --> 02:06.770 So this was in correspondence and it shows that actually Black was able to get a good game from this 02:06.770 --> 02:07.550 position. 02:10.100 --> 02:16.880 And yes, what does White actually play if Bishop takes C six, B takes, this should be even. 02:16.880 --> 02:21.920 And you might think, well, surely why it has more violent continuation than Bishop. 02:21.920 --> 02:23.000 Take C six. 02:23.000 --> 02:23.810 Yeah. 02:23.810 --> 02:24.680 G five. 02:24.710 --> 02:29.240 But what happens after Knight takes D for the bishop's hit on B five. 02:29.930 --> 02:35.210 So queenside is d4 this becomes a little bit risky piece down. 02:35.210 --> 02:36.980 Yes we have got g takes h six. 02:36.980 --> 02:41.690 But what if Bishop F six we have got rook takes g seven check. 02:41.870 --> 02:42.800 Sure. 02:43.130 --> 02:45.830 So that if Bishop takes G seven, we're going to mate. 02:45.950 --> 02:54.980 But what if King H eight Queen A for this position with Bishop D four Black has resources Queen a five 02:54.980 --> 03:03.050 check king of one bishop takes the four queen takes d4f6 queen D free threatening mates. 03:03.050 --> 03:04.670 This is just an example. 03:04.910 --> 03:06.590 And essentially. 03:08.890 --> 03:13.510 White can use the queen on DD free to basically bail out from perpetual check. 03:13.510 --> 03:17.920 So Bishop B five and white bells up perpetual check. 03:18.100 --> 03:19.180 So first. 03:22.030 --> 03:22.540 Here. 03:22.540 --> 03:27.670 We can play four if we want to delay the perpetual check. 03:27.670 --> 03:31.030 So Rook H seven, G seven and perpetual check. 03:31.030 --> 03:32.920 So that's not very glamorous. 03:32.920 --> 03:34.000 G five Basically, yeah. 03:34.000 --> 03:38.980 There's an issue with B five here if need C six. 03:40.750 --> 03:41.020 Yeah. 03:41.020 --> 03:41.590 As mentioned. 03:41.590 --> 03:41.730 Yeah. 03:41.770 --> 03:43.870 This, this position is just going to be. 03:44.140 --> 03:46.690 No, no, actually we haven't mentioned this position. 03:49.640 --> 03:50.460 Let's just mention it. 03:50.460 --> 03:53.850 So Bishop takes C6, Bishop takes six B takes. 03:54.060 --> 03:57.210 Won't councils here, Let's say Bishop takes H four. 03:57.810 --> 04:03.360 This is also funny enough, not that easy just because we've got a semi open g GFR. 04:03.360 --> 04:05.820 It's not the end of the world for blank just yet. 04:06.300 --> 04:09.000 Queen of 6g1. 04:09.000 --> 04:13.530 Why has a small maybe small edge, but it could slip away. 04:13.530 --> 04:20.970 You know this looks even engines assess this is about equal if we try and point a five. 04:22.500 --> 04:25.530 Then actually Black has a key resource here, funnily enough. 04:25.530 --> 04:26.460 D for. 04:28.830 --> 04:38.190 If Bishop takes H six bishop before c3d takes breaks once King is attacked and off the Bishop. 04:38.260 --> 04:43.410 I think this is just about even so, it's absolutely fascinating to analyse this. 04:43.770 --> 04:45.900 It turns out actually, yeah. 04:45.930 --> 04:50.760 Castling, believe it or not, might not be as bad as it seems. 04:50.760 --> 04:54.060 So Bishop takes h4 is actually an inaccuracy. 04:54.060 --> 04:58.860 White Castle's queenside and now Bishop f6 is played. 04:58.890 --> 05:06.780 If Bishop G five we can play F4 here and in this position of the Bishop e 7.5, this is going to end 05:06.780 --> 05:15.540 up being very nice for why, if Bishop f6 Bishop C five stopping the King from Castling white is a big 05:15.540 --> 05:16.410 advantage there. 05:17.370 --> 05:19.590 Otherwise, let's say castling. 05:20.160 --> 05:23.430 Bishop takes C six, B takes Queen H to. 05:24.900 --> 05:26.480 And this is a strong attack. 05:26.490 --> 05:28.290 This is now a strong attack. 05:28.290 --> 05:29.620 Why it can play rook tanks. 05:29.640 --> 05:30.780 G seven check. 05:32.280 --> 05:33.470 King G seven. 05:33.480 --> 05:34.890 Bishop D four check. 05:36.540 --> 05:37.680 King H seven. 05:38.250 --> 05:40.220 H one Black has the resource. 05:40.230 --> 05:41.520 Bishop G five. 05:41.760 --> 05:44.250 But funny enough, White is crushing it here. 05:44.280 --> 05:51.180 Can you see this technically amazing kind of preventative attacking move in this position for 200 points? 05:52.920 --> 05:54.000 What would you play here? 06:07.460 --> 06:08.830 It's quite an amazing move. 06:08.880 --> 06:14.840 Bishop E5 If we played F6 immediately, which is really tempting, Black has Quincy seven. 06:18.010 --> 06:22.750 And we don't really want the Queen's coming off of the you know, the Queen's coming off is not going 06:22.750 --> 06:23.620 to be great. 06:24.160 --> 06:28.720 And if Bishop e five, then Queen takes E five exploiting the pin, and that's a disaster. 06:30.430 --> 06:31.660 So that would be a rook up there. 06:31.660 --> 06:36.940 So Bishop e five, though, funnily enough, prevents all of that stuff if we go back. 06:38.940 --> 06:39.810 So. 06:43.350 --> 06:44.850 In that continuation. 06:45.600 --> 06:47.370 Let's go back into that continuation. 06:48.660 --> 06:50.280 So, Bishop D for check. 06:52.140 --> 06:54.120 And here. 06:54.120 --> 06:54.720 Yeah, that's. 06:54.720 --> 07:02.730 Imagine this position again, Bishop if I put it black, do so this is crushing If f6f takes. 07:02.730 --> 07:03.240 Yeah. 07:03.240 --> 07:06.780 The Kings had it really, you know, like, for example, like that. 07:06.780 --> 07:09.030 So yeah, it is fascinating. 07:09.210 --> 07:20.400 But Bishop six was played, we have 9 to 5 if King B won here, this is also a decent move. 07:20.400 --> 07:28.680 Actually in 1964 we insert Bishop takes these seven Czech Queen, 67 Bishop takes D for this position 07:28.890 --> 07:32.460 with inserting a check here is going to be better for us. 07:32.460 --> 07:36.420 So now it's five we have Bishop takes her five. 07:37.620 --> 07:44.820 If Black Castle is here, different ball game nine takes H six check G takes. 07:44.820 --> 07:49.050 There's actually a strong G five to open up that G file. 07:49.710 --> 07:53.940 So say Bishop takes G five isn't played. 07:53.940 --> 08:00.870 If Bishop E five we can take our time with Queen takes D five, Bishop e six, Queen E four. 08:00.870 --> 08:02.160 So we're hitting the Queen. 08:03.060 --> 08:08.460 And in this situation, Bishop D free threatens checkmate on H seven. 08:08.970 --> 08:10.350 Let's say black is forced to play. 08:10.350 --> 08:17.460 This Bishop takes P to check, King takes B2, Queen takes A to check King C one queen, a free check 08:17.460 --> 08:25.980 King D to Queen B four check to defend against being mated, but white ends up being significantly better 08:25.980 --> 08:26.700 here. 08:28.530 --> 08:30.450 So yeah, fascinating stuff. 08:32.840 --> 08:38.780 Aside from Bishop takes F five, if G six, there's Bishop C five to keep the king in the center. 08:39.230 --> 08:40.860 So here Bishop takes her five. 08:40.880 --> 08:42.470 This is just better for wait. 08:43.370 --> 08:48.230 And if G takes her five, Queen takes the five with the king kept in the center. 08:48.500 --> 08:51.080 This is bad news for black in this particular scenario. 08:51.080 --> 08:58.880 After Bishop take six puncturing the Dart square control so we can play Queen D for looking at H eight. 08:58.880 --> 09:01.880 And this is nasty with the king in the center. 09:01.880 --> 09:04.340 Queen E free taking your time a bit. 09:04.910 --> 09:05.990 Queen takes E six. 09:05.990 --> 09:07.220 It's going to be crushing. 09:07.220 --> 09:08.780 Can you see a crushing blow here? 09:08.780 --> 09:10.130 What is won't play hair. 09:12.250 --> 09:15.630 You know, we just disconnect the Queen from E seven for ten points. 09:15.630 --> 09:16.740 Rook dd six. 09:17.070 --> 09:18.630 So Queen takes queen twice. 09:18.630 --> 09:19.620 Yeah, we're winning there. 09:19.950 --> 09:21.290 So fun stuff. 09:21.300 --> 09:25.710 So anyway, Bishop takes that five is played G tanks. 09:25.890 --> 09:27.330 We have a six. 09:27.510 --> 09:31.530 Bishop take C six check, B takes Bishop C five. 09:31.530 --> 09:33.360 So the Kings kept in the center. 09:33.660 --> 09:35.220 We have Rook B eight. 09:37.420 --> 09:43.600 And now, funny enough, you might find this a little bit strange, but before you might think, Hang 09:43.600 --> 09:43.720 on. 09:43.720 --> 09:45.910 Isn't there a cozier move? 09:46.810 --> 09:48.010 Sort of before? 09:49.120 --> 09:57.940 The funny thing is about this position, if we play C free, this is this is a funny position for the 09:57.940 --> 09:58.180 king. 09:58.180 --> 09:59.440 Safety battles. 10:01.380 --> 10:04.740 It's not that bad for Black, believe it or not. 10:04.890 --> 10:14.220 Black has a key move for king safety, which you might give a give it a double exclamation mark if it 10:14.220 --> 10:17.750 was the older informed to symbols for very strong move. 10:17.760 --> 10:20.070 Can you see a very strong move for black hair. 10:21.840 --> 10:27.720 Yeah black could play King seven if Bishop Yeah. 10:27.830 --> 10:36.840 This means that we can never really make use of C four because of the B two issue, which explains somewhat 10:36.840 --> 10:44.940 why cop Off chose b4 he wants to reserve the possibility of C4 without this rook glaring down at B two. 10:45.510 --> 10:51.030 So if, if we only have this position Bishop D for Rook, it's black's got a small edge. 10:51.540 --> 10:54.660 Funny enough, black's got the more solid pawn structure. 10:54.660 --> 11:00.660 White is played like an attacking player with a weakened pawn structure here, but with B four it's 11:00.660 --> 11:01.650 slightly different. 11:01.650 --> 11:03.600 So now we can play C for. 11:06.110 --> 11:07.700 So that's very interesting. 11:11.080 --> 11:12.070 And here. 11:13.590 --> 11:14.780 Tho plant goes wrong. 11:14.790 --> 11:20.710 If b5 black still could play kingly seven and even with the RAF of C4 king. 11:20.730 --> 11:23.370 c7c takes C techs. 11:23.370 --> 11:30.890 Let's examine Queen D free Queen D seven Just that black off of that Queen C six check King. 11:30.900 --> 11:33.270 See, this is even this position even. 11:33.270 --> 11:36.120 I mean, White's king is getting potentially exposed as well. 11:36.660 --> 11:37.300 If Rook. 11:37.320 --> 11:38.460 B seven. 11:39.930 --> 11:40.800 C four. 11:40.800 --> 11:41.790 D four. 11:42.090 --> 11:43.680 This is good for whites. 11:44.520 --> 11:45.270 This is very different. 11:45.480 --> 11:45.930 G three. 11:45.960 --> 11:50.780 Exploiting that third rank, not Bishop 64. 11:50.820 --> 11:56.210 This simplification would just help Black's king safety cause and black would be fine. 11:56.220 --> 12:01.710 So the critical test would be Rook G free here h5 Rook free. 12:01.710 --> 12:08.640 And yeah, I mean, black's in trouble here because the upcoming rook takes 86. 12:08.640 --> 12:10.050 So this is just desperate. 12:11.900 --> 12:13.310 And we could just take on E seven. 12:13.310 --> 12:14.360 Take on a six. 12:14.360 --> 12:14.910 So yeah. 12:14.930 --> 12:15.350 Interesting. 12:15.350 --> 12:16.880 But Rugby five is a mistake. 12:16.880 --> 12:17.900 It provides a tempo. 12:17.900 --> 12:19.880 Gaynor for C4. 12:20.060 --> 12:25.070 Well, Black's intention is to sacrifice the exchange to try and make the most out of this bishop. 12:25.910 --> 12:27.710 So it's an interesting idea. 12:27.860 --> 12:29.050 Rook g one check. 12:29.090 --> 12:29.720 Kingsley seven. 12:29.720 --> 12:30.510 C four. 12:30.530 --> 12:32.150 So, Boris Spassky's idea. 12:32.150 --> 12:33.890 Sacrifice the exchange here. 12:37.340 --> 12:41.750 Beat Saints, Bishop G five and four. 12:42.920 --> 12:47.000 And now very interesting, Queen F six looking at a one. 12:48.440 --> 12:54.470 So this is a crunch moment for how allowing counterplay could be fatal for us. 12:55.070 --> 12:59.450 The difference between allowing counterplay or not Higgs or king is exposed and it looks as though, 12:59.450 --> 13:02.260 well, hold on, we're just going to be a whole rook up if we take on G five. 13:02.270 --> 13:05.390 Now, do you take on G five or do you do something else? 13:06.410 --> 13:08.840 So for 100 points, what would you play here? 13:12.180 --> 13:15.390 It looks as though visually, you know, this rook has even got out of bed yet. 13:15.420 --> 13:18.450 How on earth could this rook help the queen if we take on G five? 13:20.560 --> 13:21.580 Impossible, right? 13:25.880 --> 13:27.580 You know, the alarm clock hasn't gone off this. 13:27.720 --> 13:29.930 It's still lying there in bed after all this time. 13:29.930 --> 13:32.630 But the thing is, sea tax is played. 13:32.660 --> 13:33.920 It's less risk. 13:34.220 --> 13:36.050 If F takes there is a risk. 13:36.050 --> 13:38.090 And it's more than a risk. 13:38.090 --> 13:38.420 Actually. 13:38.420 --> 13:39.890 Queen a one check. 13:40.070 --> 13:43.490 The thing is Queen saying A to Jack. 13:43.490 --> 13:47.690 Now let's say we were playing for a win with King de There's Queen. 13:47.690 --> 13:57.200 Take C for checking E for at this moment the rook gets straight out of bed with H text g five activate 13:57.230 --> 14:00.440 straight out and as Queen E four if needed. 14:00.530 --> 14:01.670 If zero case one. 14:01.670 --> 14:02.810 This is not nice. 14:02.810 --> 14:08.930 Queen G to H for all of a sudden it's under big attack. 14:09.320 --> 14:13.880 You know, this position is getting rather embarrassing. 14:13.880 --> 14:14.750 Ouch. 14:15.110 --> 14:18.800 So yes, C takes the five is so much safer. 14:18.800 --> 14:21.340 Don't activate the opponent's pieces. 14:21.350 --> 14:23.030 So queen a one check. 14:23.030 --> 14:25.520 King C two queen takes a two check. 14:25.520 --> 14:29.270 King D free queen takes RD to check one else. 14:29.420 --> 14:34.520 Now, there's some nuance here in a variation I'd like to show you if the Queen's didn't come off. 14:34.520 --> 14:35.660 Queen B free check. 14:35.780 --> 14:38.840 Queen C three, Queen B five Queen for. 14:40.200 --> 14:44.250 And let's say Black played Bishop eight four. 14:44.430 --> 14:50.730 Would you be in a rush to take the Queens off here, or would you do something else in this position 14:50.730 --> 14:51.840 for ten points? 14:53.900 --> 14:56.960 Because surely you could take the queens off and then move the rook, right? 14:57.830 --> 15:07.390 It turns out here, Rook, one is so much stronger if we play Rook G one and then DD six we've got nice 15:07.400 --> 15:09.440 pawns and look at the opponent's split pawns. 15:09.440 --> 15:12.210 We've still got to think positioning about pawn structure. 15:12.230 --> 15:19.070 The point is, if we took on B5, we're healing Black's pawn structure after moving a rook. 15:22.360 --> 15:22.990 Here. 15:24.970 --> 15:28.570 So this is setting a trap. 15:28.780 --> 15:32.320 If Bishop takes, we have check and another check to win the rook. 15:32.560 --> 15:33.730 Let's put that on the board. 15:34.390 --> 15:35.170 Check. 15:35.950 --> 15:38.110 So the king goes to the background. 15:38.110 --> 15:39.520 We play a check, and we win the rook. 15:39.520 --> 15:40.180 Right. 15:41.200 --> 15:43.540 And that's going to be good for white. 15:43.870 --> 15:44.680 But. 15:49.480 --> 15:57.490 But after he takes the five yea blacks positional kind of exchange, sacrifice is a little bit more 15:57.490 --> 15:58.000 justified. 15:58.030 --> 16:03.250 White's advantage here is significantly smaller. 16:03.550 --> 16:04.990 It's only a slight advantage. 16:04.990 --> 16:07.720 So yes, I mean disposition. 16:07.780 --> 16:09.970 Got to be careful with these pawns. 16:10.060 --> 16:17.890 So yes, it's so much stronger just to play Rook G one here. 16:20.850 --> 16:24.900 And in the case of sea, takes blacks dismantling the structure. 16:25.800 --> 16:27.870 So we have options. 16:27.870 --> 16:32.100 Then in this position, we can dismantle black structure. 16:32.100 --> 16:34.710 The structural difference is the big deal. 16:35.550 --> 16:41.160 So we want to be the exchange up under ideal conditions with good pawn structure as well. 16:41.160 --> 16:44.280 So Queen takes DD to though was played. 16:44.280 --> 16:49.620 That's all irrelevant because Queen takes DD to check, Rook takes Bishop takes F form. 16:51.180 --> 16:53.280 We have now Rook a two. 16:55.760 --> 16:56.930 And this is a big problem. 16:56.930 --> 17:01.820 C to 65 rotates a six, H five. 17:03.020 --> 17:05.810 We have King D for actual king. 17:05.840 --> 17:06.070 Thanks. 17:06.080 --> 17:06.490 D five. 17:06.500 --> 17:09.170 There's not really enough compensation. 17:10.760 --> 17:12.050 For the exchange down. 17:12.050 --> 17:20.000 We have Rokeby eight and I'm breaking up black spawns of F six or providing a meaningful hook on E seven. 17:20.000 --> 17:20.660 So G. 17:20.660 --> 17:21.390 Thanks, Rook. 17:21.410 --> 17:22.040 Thanks. 17:22.040 --> 17:26.900 Bishop moves, Rook takes F seven, check King the eight and now the rook f h hack. 17:26.900 --> 17:29.090 Boris Spassky resigned. 17:29.090 --> 17:36.020 So why did he resign If King D seven we can play the neat C six check as one example rookie seven check 17:36.020 --> 17:38.780 and we end up playing Rook takes B check. 17:38.780 --> 17:43.190 Bishop takes eight ROKEBY seven picking up the bishop. 17:43.970 --> 17:47.270 And you might ask instead of King D seven, King C seven. 17:47.270 --> 17:49.490 We have just Checkmate Hare immediately. 17:51.620 --> 17:52.430 Yes. 17:52.430 --> 17:54.350 So end of game after Rook, a fake check. 17:54.410 --> 17:56.030 So a fascinating game. 17:58.160 --> 18:04.520 It's interesting to see these highly tactical sharp variations in karpov's hands. 18:05.240 --> 18:12.440 So his expression about if there's a choice between a large advantage with a bit of controversy basically, 18:12.440 --> 18:18.740 or the small advantage microscopic even, which is much clearer, not so murky, he'll pick the clearer 18:18.740 --> 18:19.220 one. 18:19.220 --> 18:26.510 But we see a vivid example here that we don't want to be tempted just because we're a rook up to allow 18:26.510 --> 18:27.500 counterplay. 18:27.800 --> 18:30.050 So there's very fascinating variation. 18:30.050 --> 18:34.060 So he kept control to a large extent all the way through. 18:34.070 --> 18:35.270 So very, very interesting game. 18:35.270 --> 18:36.440 I hope you enjoyed this one. 18:37.280 --> 18:44.330 So Boris Spassky was a bit of a major victim of Anatoly Karpov, know Boris Spassky more than ten times 18:44.330 --> 18:48.200 in their match record and only lost like very, very occasionally. 18:48.200 --> 18:51.590 Just one, I believe so, yeah. 18:52.460 --> 18:53.900 So something like 13 one. 18:53.930 --> 18:59.450 If you look at the records, we've got some draws, but yeah, quite, quite the customer. 18:59.450 --> 19:01.760 Boris Spassky of Anatoly Karpov. 19:03.560 --> 19:06.350 Och, I hope you enjoy this so much.
