WEBVTT 00:01.080 --> 00:01.890 Hi there. 00:01.920 --> 00:08.300 In this lecture, we see an amazing game between Robert Byrne against Bobby Fischer. 00:08.310 --> 00:16.020 So this is in 1963, the US Championship Round three we see D fall from Robert Bunn nine 10:06 p.m. 00:16.020 --> 00:25.920 Fischer c4 g6g free C6 Bishop G2, d5 C tanks C tanks. 00:25.920 --> 00:29.790 So we have a symmetrical pawn structure right now. 00:30.420 --> 00:37.680 Knight C free, Bishop g7e Free Fischer consoles nine G2. 00:37.680 --> 00:40.200 So the Knights are slightly different. 00:40.590 --> 00:46.650 This one's placed on A2 rather than F3 if we want to mirror the pieces as well. 00:46.650 --> 00:49.560 Black hasn't committed to E6 though. 00:49.920 --> 00:58.650 Knight C six consoles are now b6b frame bishop A6 Bishop A3 so White's imitating black. 00:58.650 --> 01:03.510 They're on this queenside which looks very symmetrical indeed. 01:03.690 --> 01:08.250 We c Rookie ain't Queen D two So there's a question here. 01:08.400 --> 01:13.710 Surely E5 is out of the question to have a weakened D5 pawn? 01:14.820 --> 01:16.920 Well really depends on the position. 01:16.920 --> 01:21.000 And here even engines now love Fischer's next move. 01:21.360 --> 01:29.520 Fischer actually does play E5, giving himself the isolated Queen's pawn IQ p for short. 01:29.520 --> 01:35.910 So after D takes E5 because what else could this have been avoided? 01:35.910 --> 01:38.220 Well, possibly. 01:38.310 --> 01:41.910 Let's say Rook fc one Black could have a good game. 01:41.910 --> 01:51.540 He tanks d4 this position of the 18th e fal rook since my f4 black has that hook on the E4 square with 01:51.540 --> 01:53.820 that rook ready and waiting to support the hook. 01:54.360 --> 01:59.550 And we get a situation here which, for example, this could liven up. 02:01.860 --> 02:04.680 Bishop takes A1 Roberts A1 95. 02:04.680 --> 02:06.390 Black is going to get a small edge here. 02:06.420 --> 02:10.740 That's a dynamic thing for White to do that to take on E4. 02:10.740 --> 02:14.670 But otherwise, what about the pressure on D4? 02:14.700 --> 02:19.650 Yeah, that's so yeah, this is a difficult position for White to have to give up the exchange. 02:21.000 --> 02:23.430 So, yes, that's one impact. 02:23.430 --> 02:29.850 Potentially that hook on E4 basically could be made use of pretty soon with the rook on E8. 02:31.320 --> 02:40.350 If this isolated queen pawn structure was not accepted, if we go back here and consider actually. 02:42.080 --> 02:42.950 Also. 02:45.260 --> 02:46.520 Bishop the fall. 02:47.370 --> 02:52.260 It is interesting as well if the tanks e free. 02:53.570 --> 02:55.220 This position with it. 02:55.270 --> 02:56.510 I have to check. 02:56.840 --> 02:57.890 Bishop takes a one. 02:57.890 --> 03:01.110 Is very, very dangerous after rookie one check. 03:01.150 --> 03:01.580 Yeah. 03:01.660 --> 03:03.940 There are various possibilities for black. 03:03.950 --> 03:07.070 So even if Black wasn't given the IQ structure. 03:07.070 --> 03:15.620 But anyway, black was D tanks e5 and we have 96 e5 and now we have the case of the wrong Rook. 03:15.830 --> 03:19.020 There's two rooks which could have gone to D one. 03:19.040 --> 03:21.920 This one has a kind of weakness of the last move. 03:21.920 --> 03:25.730 F2 is a bit weaker and this becomes. 03:26.610 --> 03:30.030 A kind of priority for black to make use of F2. 03:30.060 --> 03:33.060 Pretty soon if rook add one. 03:34.920 --> 03:45.990 This is more testing say Quincy eight 1965 1985 Bishop 65 Rook the eight. 03:47.130 --> 03:53.700 And the thing is here that say four black has a resource here. 03:53.730 --> 03:55.080 Can you see what that is? 03:56.670 --> 03:59.340 Which could lead black to a small edge? 04:01.130 --> 04:01.560 Okay. 04:01.610 --> 04:03.460 Black could try and get onto this. 04:03.470 --> 04:06.320 We can diagonal by taking out the thing ghetto bishop. 04:06.890 --> 04:11.810 And quite often, if you weaken the opponent's king, it's like your pieces get promoted. 04:11.900 --> 04:15.290 This bishop is now kind of more dangerous than usual. 04:16.010 --> 04:20.960 It's more than free because it's getting involved in mating combinations, potentially. 04:21.830 --> 04:26.930 If Queen D two, Queen C sex white would have to give up material. 04:26.930 --> 04:30.100 Actually how white defend on diagonal. 04:30.110 --> 04:38.840 And if this is the case here, then Black is doing quite well in this position with a small edge. 04:39.350 --> 04:41.150 So that was interesting. 04:41.960 --> 04:47.810 It's much more interesting for White to have done Rook 81 rather than Rook 51. 04:47.810 --> 04:55.220 So after this move we see Knight D free and this is really quite an annoying night indeed. 04:55.220 --> 04:56.720 We see Queen C two. 04:56.810 --> 05:02.450 So as if the friend, you know, Rook 63 and Grandmasters 40 Fischer might have been in trouble here. 05:02.600 --> 05:03.950 What is going on here? 05:05.270 --> 05:09.230 Well, the thing is, he plays now a brilliant move. 05:09.860 --> 05:16.700 If instead of the Queen C2 though, just have a look at 94, then there's no E4 using that hook and 05:16.700 --> 05:19.370 this would be cementing the knight on D3. 05:19.880 --> 05:23.600 So this possession, for example, would be quite nice. 05:23.870 --> 05:28.250 Black has Bishop C free and this is very pleasant for black. 05:28.250 --> 05:31.370 That isn't such a weakness having the knight on D3. 05:31.370 --> 05:33.410 It's just it's a nice position. 05:33.500 --> 05:35.040 So Queen C2 though. 05:35.060 --> 05:45.020 So this next move by Fisher is absolutely brilliant and it kind of recognizes basically when we have 05:45.020 --> 05:51.530 a dynamic pawn structure like an ice queen, Queen's pawn with the extended hanging pawns, sometimes 05:51.530 --> 05:56.270 these guys are getting in the way for attacking potential against the king. 05:56.960 --> 05:58.610 So just bear that in mind. 05:59.890 --> 06:05.510 But also, of course, we need to bear in mind if we weaken the opponent's king, we're giving our pieces, 06:05.510 --> 06:11.300 you know, potentially a promotion because they might be more valuable for hunting the king. 06:11.870 --> 06:14.480 So here the bishop is only in a support role. 06:14.480 --> 06:17.150 So I'm about to show you the Fisher move now. 06:17.990 --> 06:19.070 Knight takes F2. 06:19.070 --> 06:21.140 Well done if you found this 100 points. 06:21.140 --> 06:22.550 So King tanks. 06:22.940 --> 06:28.640 And the point is Knight G4 check King Ju on the king can't go to F3. 06:28.940 --> 06:29.870 It's out of the question. 06:29.870 --> 06:31.880 Rook takes every check is possible. 06:31.940 --> 06:34.310 Doesn't matter about the knight on G4. 06:35.360 --> 06:41.600 If King takes G4, there's h five check and black gets mated soon like this. 06:41.600 --> 06:42.320 Checkmate. 06:43.100 --> 06:47.090 And if King f4 again black gets mated soon like this. 06:47.720 --> 06:49.250 So this would be checkmate. 06:49.250 --> 06:51.470 So the king has to go back. 06:51.830 --> 07:00.380 Knight takes E frame Queen D and here the beautiful point about this pawn, it's kind of a constraints, 07:01.130 --> 07:04.910 potentially Fish and Nell plays a very, very strong move. 07:05.650 --> 07:09.760 So which way to take the bishop or the rook for 100 points? 07:09.760 --> 07:12.610 Would you take the bishop or would you take the rook? 07:15.190 --> 07:18.820 The right thing to do here is actually to take the bishop because it's weakening. 07:19.650 --> 07:20.670 The opponent's king. 07:20.670 --> 07:23.340 So weakening the opponent's king, especially the light squares. 07:23.340 --> 07:24.990 That was the guardian bishop of the Lion Square. 07:24.990 --> 07:30.660 So it actually promotes this guy because this guy can work on the light squares now without the counterpart. 07:32.910 --> 07:38.410 If Fisher had taken on d one route. 07:38.430 --> 07:39.540 Thanks d one. 07:41.330 --> 07:44.000 This is nothing to really write home about here. 07:44.030 --> 07:47.120 Bishop takes the five is an equal position. 07:48.950 --> 07:57.740 There was, however, an alternate to 1962, which was also very strong here, showing the actually. 07:57.770 --> 08:00.800 Hold on the four. 08:03.050 --> 08:06.020 It offers the special blank on ice. 08:06.020 --> 08:07.460 And the thing is. 08:09.590 --> 08:12.020 If the night moves here. 08:13.830 --> 08:20.160 Then there's no it takes G2 and rotates E to, as example, saying the knight moves, Knight takes G2 08:20.160 --> 08:21.780 and then rotates EA two. 08:22.770 --> 08:25.290 And given that the case of Bishop takes eight. 08:25.320 --> 08:31.890 We do get the Queen menacingly looking at G2 teammates Knight for protecting G2. 08:32.280 --> 08:36.150 This position is very strong for black of the C2. 08:36.420 --> 08:43.890 Bishop takes A1, Rogue takes A1, Knight D one and nothing else but French thing. 08:44.280 --> 08:51.430 The e one square if Queen D2 trying to hold e one queen F3 and it's quite vicious. 08:51.450 --> 08:56.820 Queen f1 mate France and trade queen takes G4 he won't just crumbles her basically. 08:56.820 --> 09:00.150 This is a crushing position to be in. 09:02.880 --> 09:03.270 So. 09:03.270 --> 09:03.890 Okay. 09:03.900 --> 09:04.230 Yeah. 09:04.230 --> 09:08.130 There's very, very interesting possibilities here, including the. 09:08.670 --> 09:09.630 That was also very strong. 09:09.630 --> 09:13.050 But 1962 is absolutely amazing what we're about to see. 09:13.470 --> 09:14.970 King takes G2. 09:19.300 --> 09:23.020 Because if you don't testify, we're just going to take on Ito, for example. 09:23.260 --> 09:24.700 So King takes two. 09:24.700 --> 09:26.590 But now what's the key move here? 09:27.430 --> 09:31.930 So the pieces have gone up in value because the king's weaker. 09:31.930 --> 09:36.820 We can assume that it's not just that piece, but potentially other pieces could be involved in king 09:36.820 --> 09:40.540 hunting as a sport and come together as a team here. 09:41.920 --> 09:50.620 Okay, so here black plays now default fisheries, letting the pawn go to get this diagonal access. 09:51.160 --> 09:55.090 That's the funny thing with dynamic pawn structures, especially the ice Queen pawn. 09:55.090 --> 09:56.410 Sometimes it's just a restraint. 09:56.410 --> 10:02.530 Sometimes you just want to take it to the next level, make it disappear as a sort of line clearance 10:02.530 --> 10:03.340 tactic. 10:04.300 --> 10:12.640 So yes, and the same with quite often, if it was hanging pawns, it's often a pawn sack just to let 10:12.640 --> 10:19.360 a pawn go just often liberates the pieces, which gives us good potential for attacking combinations. 10:19.540 --> 10:22.000 So here 964 is played. 10:24.200 --> 10:25.220 It's a difficult position. 10:25.220 --> 10:32.660 If the night moves, we're playing rock tanks, aid to Czech bishops, quite useful where it is at the 10:32.660 --> 10:34.250 moment for such tactics. 10:34.580 --> 10:38.000 So Knight takes D4 now Bishop b7 Shank. 10:38.750 --> 10:41.240 And this looks very scary after killing of one. 10:42.770 --> 10:43.970 Very, very scary. 10:48.000 --> 10:50.430 If Qing ji won. 10:51.270 --> 10:55.710 Black has a tactical sequence here to win material at the very least. 10:56.220 --> 10:57.750 Can you see what that is? 11:01.430 --> 11:01.610 Okay. 11:01.760 --> 11:03.710 There's Bishop takes the fall check. 11:03.920 --> 11:06.080 And here, what does black play? 11:07.490 --> 11:09.140 It's actually a funny move. 11:09.170 --> 11:10.520 Check who checks Rookie one. 11:10.520 --> 11:10.880 Check. 11:10.880 --> 11:12.740 So the rook takes protecting the queen. 11:13.600 --> 11:15.950 And otherwise, we just end up. 11:15.950 --> 11:19.910 We take the queen here to win the A1 rook and win the exchange up. 11:20.780 --> 11:23.630 So the king went to F1. 11:23.930 --> 11:28.340 And now there's two really great moves with the same kind of goal achieved. 11:29.210 --> 11:32.390 So what do you think one of the two moves are for 500 points? 11:32.390 --> 11:33.140 What would you play here? 11:33.140 --> 11:39.800 The value of all the pieces has gone up all of a sudden because the king is weaker, because the king 11:39.800 --> 11:45.350 is weaker, the pieces of more things to do, more fun is available to them. 11:45.830 --> 11:47.150 And we see Queen D seven. 11:47.150 --> 11:49.490 Queen Kate would have done the job as well. 11:49.820 --> 11:56.150 The huge frappe basically is Queen H three and actually White resigned her move 21. 11:56.630 --> 11:59.030 The grandmasters were completely shocked by this game. 11:59.030 --> 12:01.370 They thought fish would have been slightly worse. 12:01.370 --> 12:03.050 We've lost that in Queen's Pawn. 12:04.070 --> 12:08.390 So yes, a total of the unexpected, to say the least. 12:08.900 --> 12:11.450 So let's look at various options here. 12:11.450 --> 12:17.960 If DB five, let's say queen and free check. 12:17.960 --> 12:20.930 And there's a key move here which is crushing. 12:20.930 --> 12:22.910 Funny enough, can you see what that is for?
