WEBVTT 00:01.000 --> 00:01.760 Hi there. 00:01.780 --> 00:07.630 In this lecture, we see vastly immature playing against Anatoly Karpov in the 1994, the enormous tournament 00:07.630 --> 00:08.560 round five. 00:08.560 --> 00:11.590 So this was one of Karpov's greatest ever tournaments. 00:11.590 --> 00:14.050 So it's fascinating to see his wins there. 00:14.170 --> 00:17.410 The fall from nine times six from Karpov. 00:17.440 --> 00:18.100 C four. 00:18.100 --> 00:20.680 E six, nine two and 3b6. 00:20.680 --> 00:24.190 So Queen's Indian Territory, G3 Bishop A six. 00:24.820 --> 00:32.020 This teases whites to protect the pawn and disrupt the four, so default could be a more meaningful 00:32.020 --> 00:32.860 target. 00:33.220 --> 00:36.100 We have Bishop just dropping back to B seven now. 00:36.280 --> 00:41.440 Bishop G2 are now exploiting the D pawn slightly looser than before. 00:41.470 --> 00:42.430 C five. 00:42.820 --> 00:47.440 We have E4, so Karpov is going into the hedgehog structure. 00:47.980 --> 00:48.880 If D five. 00:48.880 --> 00:54.910 Instead this is viable for to play like this with stage four pinning the d5 pawn. 00:54.910 --> 00:57.610 So this position should be about equal. 00:58.630 --> 01:02.830 E4 though is played, which is actually more kind of critical for black. 01:02.830 --> 01:08.310 C takes the four white consoles DD 69634. 01:08.320 --> 01:10.630 So Karpov playing with a hedgehog here. 01:10.780 --> 01:17.010 So Queen DD seven if Bishop e seven might be able to get an advantage of E five. 01:17.020 --> 01:19.300 So this looks at the B seven bishop. 01:19.510 --> 01:27.790 If Bishop takes G to E, takes F six, Bishop takes have six, Y can play nine, takes E six here after 01:27.790 --> 01:31.540 F takes six, King takes G to one has a small edge. 01:31.780 --> 01:39.520 So Queen D seven safeguards the bishop on B seven We have rookie one, Bishop E seven, knights B one. 01:39.520 --> 01:43.750 So this is a nice positional maneuver in which to reposition the knight. 01:44.170 --> 01:50.160 9c69c Free Knight takes DD four Queen takes the four Black castles. 01:50.170 --> 01:52.360 B Free Rook 58. 01:53.800 --> 01:58.390 So here it looks as though it's about equal at the moment. 01:58.960 --> 02:02.650 Rook AB eight We have H Free Bishop eight. 02:02.680 --> 02:03.640 G four. 02:03.670 --> 02:07.570 Now there are some dark square weaknesses creeping into White's possession. 02:07.570 --> 02:08.710 Pawns though going backwards. 02:08.710 --> 02:13.420 We have h6a4a6 bishop a free. 02:13.420 --> 02:22.660 So why is looking at D six We have Quincy eight, Bishop B two, Queen C five, Queen DD two. 02:22.660 --> 02:25.000 So she wants to keep the Queen's on. 02:26.140 --> 02:31.630 And also of course B takes will look at a backward pawn on B free one won't want to do that. 02:32.470 --> 02:41.200 We have 97 rook, 81, 95, 92 and here Bishop G5 is played. 02:42.340 --> 02:43.750 So the f pawn is Penns. 02:43.750 --> 02:44.740 There's no f four. 02:44.740 --> 02:45.850 So this is a nuisance. 02:45.850 --> 02:47.080 Isn't that Queen C free? 02:47.080 --> 02:54.550 We have Bishop of six and with this move it looks as though nine takes g four might be frightened. 02:54.550 --> 03:00.700 Looking at the Queen, we have Bishop a free looking at Black's queen. 03:00.850 --> 03:03.760 So here this is no longer working. 03:03.760 --> 03:06.130 Nine g for white would just take the Queen. 03:06.460 --> 03:10.120 And here what ends up being a piece up. 03:10.810 --> 03:12.310 So that's a bad idea. 03:12.310 --> 03:15.700 So basically the queen moves. 03:16.510 --> 03:21.020 So Black still has this 9/10 g for France looking at the queen. 03:21.040 --> 03:23.860 So the queen moves to d d2. 03:27.880 --> 03:37.000 Before we get into that, actually, instead of Queen C seven, we've looked at Knight's text G four, 03:37.000 --> 03:37.780 but what about nine? 03:37.780 --> 03:38.410 G six? 03:38.410 --> 03:40.240 This is actually a plausible move. 03:41.260 --> 03:47.080 Funny enough, if Queen takes off six, this position is going to be in Black's favor. 03:48.310 --> 03:59.500 So we have if Bishop take C five, this is also going to be quite nice for black if Queen C one. 04:01.100 --> 04:02.240 Quincy seven. 04:02.750 --> 04:03.380 Yeah. 04:03.380 --> 04:06.540 Black actually, overall has a small edge here. 04:06.560 --> 04:09.590 This is a very favorable hedgehog situation. 04:10.130 --> 04:15.830 So anyway, Quincy seven is played Queen DD two and we have nine. 04:15.830 --> 04:16.700 G six. 04:16.850 --> 04:20.540 So we're looking at the rook on a one. 04:20.990 --> 04:22.580 We have Rook AC one. 04:23.330 --> 04:26.690 If Bishop takes DD six, then Black just plays for five points. 04:26.690 --> 04:27.470 What would you play? 04:27.950 --> 04:28.550 Yeah, just play. 04:28.550 --> 04:31.730 Rook takes these six here and then we're winning the rook on a one after. 04:31.970 --> 04:33.860 So the rook has to move. 04:34.310 --> 04:37.790 We have Bishop e seven here. 04:38.060 --> 04:44.200 It's worth pointing out that Bishop g5i think it's worth pointing out. 04:44.210 --> 04:46.100 Bishop, do you find there's F4? 04:46.430 --> 04:49.910 And if Knight takes her four, this trick doesn't work here. 04:49.970 --> 04:51.110 E five. 04:51.380 --> 04:57.200 You might think he's winning a pawn, but actually 95 hits the Queen on C seven. 04:59.630 --> 05:02.660 So this ends up being favorable. 05:03.690 --> 05:04.710 To white. 05:05.250 --> 05:07.860 If Bishop takes the five Queen 65. 05:07.860 --> 05:15.360 And if Bishop takes the white has just one or two bishops for it's big advantage actually at this level 05:15.520 --> 05:15.960 for white. 05:15.960 --> 05:18.130 So that's winning for white, basically. 05:18.900 --> 05:22.290 So that's not actually working here. 05:22.530 --> 05:29.940 D five might be better, but even so, E takes this position is still going to be about even so, it's 05:29.940 --> 05:31.920 funny to be on the lookout for this. 05:31.920 --> 05:35.270 So we see Bishop e seven and now Queen friend. 05:35.280 --> 05:37.620 You might think, well, it's not much different, right? 05:37.620 --> 05:38.160 Is it? 05:39.300 --> 05:41.460 That Bishop shouldn't be working? 05:42.870 --> 05:45.270 Or is it working out for ten points? 05:45.270 --> 05:47.400 Is Bishop G five more effective and why? 05:47.760 --> 05:48.480 That's the important thing. 05:48.480 --> 05:51.330 Why would Bishop defy be more effective here? 05:53.490 --> 05:59.400 So one should have stayed away from the E three square because that is actually aligns to the king. 05:59.850 --> 06:04.890 Queen D phrase example for would be just a waiting game. 06:05.070 --> 06:06.030 It's even. 06:06.540 --> 06:12.390 But with Queen E three this changes things quite differently, quite massively with Bishop G five working 06:12.870 --> 06:15.960 after F for nine takes F four. 06:15.960 --> 06:16.800 Now it takes F four. 06:16.800 --> 06:23.610 And you can see a key difference now that actually 95 is completely impossible here. 06:25.460 --> 06:29.240 Because Bishop Saint free is Czech simply. 06:30.620 --> 06:32.840 So Karpov has just won a pawn. 06:35.210 --> 06:35.960 And. 06:37.430 --> 06:38.510 It's actually then the game. 06:38.510 --> 06:40.940 We've kind of been shortchanged in a way. 06:41.210 --> 06:48.500 This potentially epic game between Evans and Karpov in round five ended here. 06:48.770 --> 06:52.130 Yeah, it was just annoyed about this pawn loss. 06:53.180 --> 06:59.930 I mean, it is a significant pawn loss If Queen f2 e takes F4 seems to be the very best way to play 06:59.930 --> 07:00.500 this. 07:00.620 --> 07:07.370 So with the E five score in mind for later for using the E five square as example, like this blank 07:07.370 --> 07:13.280 wraps around the E five square and should be able to make progress eventually. 07:13.280 --> 07:17.400 It's actually harder to make progress with Bishop takes F4. 07:17.420 --> 07:26.120 It seems in my in this simulation theoretical game that even though blacks are pawn up the binds is 07:26.120 --> 07:31.690 quite good for white and may actually offer a huge amount of resistance. 07:31.700 --> 07:34.340 This situation is a huge amount of resistance. 07:34.340 --> 07:37.570 How is Black actually exploit the extra pawn? 07:37.580 --> 07:39.710 It's going to be very tricky indeed. 07:39.710 --> 07:44.510 In this position there is a bind, so the way it's played would have been, it seems e takes out for 07:44.540 --> 07:50.660 that seems a little bit more accurate to give Black some real winning chances, but in which it was 07:50.660 --> 07:58.460 so annoyed that yeah, he just resigned here after if I'm not really testing what White would play after 07:59.690 --> 08:01.970 what black would play after rather. 08:02.360 --> 08:03.230 So yes. 08:03.230 --> 08:08.390 Karpov on the lookout comp of not minding playing the hedgehog and you know Britain's Michael Adams 08:08.390 --> 08:11.270 has played the hedgehog with great success as well, it seems. 08:11.270 --> 08:17.420 You might think there's a long time to wait for a mistake, but no, it was like a major like mistake. 08:17.420 --> 08:24.350 Queenie, free this, you know, the aspects of the position here tactically, even if we just without 08:24.350 --> 08:32.200 even calculating our own moves, it seems we can by instinct say there are downsides without calculating 08:32.210 --> 08:35.690 our own moves, that the Queen is on a skewer line with the rook. 08:35.690 --> 08:40.220 The Queen is also on a skewer line with the king. 08:40.220 --> 08:45.830 I know we can't skewer on this diagonal, but it's still in the same road as the king, So it makes 08:45.830 --> 08:48.530 this Bishop G5 all the more powerful here. 08:48.530 --> 08:53.150 So it's something to look out for this instinct, for just looking at the downsides of the opponent's 08:53.150 --> 08:57.380 position, even without calculating our own moves. 08:57.380 --> 08:58.820 That's a great instinct. 08:59.240 --> 09:01.940 But the zone of weakness, provocation. 09:02.870 --> 09:09.290 One could argue when the hedgehog's structures the hedgehog is is seen as a great structure. 09:09.290 --> 09:15.650 It does seem to offer an interesting game which can stretch out and eventually the opponent can blunder. 09:15.650 --> 09:21.950 And Michael Adams has emphasized that is often look out for such games where there's a wide scope for 09:21.950 --> 09:24.410 the opponent blundering if the game can go on and on and on. 09:24.410 --> 09:30.860 So hedgehogs a very solid structure and can invite mistakes like this. 09:31.010 --> 09:33.860 So in one sense, why am I showing in this game? 09:33.860 --> 09:37.250 I think it's an important aspect that we can play a waiting game. 09:37.250 --> 09:40.340 Sometimes with solid moves and wait for the opponent to self destruct. 09:40.700 --> 09:44.630 Okay, I hope you enjoyed this your much.
