WEBVTT 00:00.990 --> 00:01.740 Hi there. 00:01.770 --> 00:08.400 In this lecture, we see a theme Geller against Max over in 1953, Zurich Candidates tournament, round 00:08.400 --> 00:09.090 two. 00:09.690 --> 00:19.620 So D4 from Ghana we have nine times six from max oer C4 e6 nine C3 Bishop before E3 the Rubinstein variation 00:19.950 --> 00:37.320 c5 a3 Bishop St C3 B Tanks c4 b6 Bishop D3 Bishop b7 F3 9692 Both sides Castle 1925 We have e4 98 Knight 00:37.320 --> 00:39.810 G Fraser I'm getting past the opening phase. 00:40.170 --> 00:42.840 It's the middle game I really want to focus on here. 00:43.800 --> 00:53.640 So C takes D4 Rook st F4 so it's getting a potentially dangerous attack by sacrificing the C4 pawn we 00:53.640 --> 00:54.180 have now. 00:54.180 --> 00:55.950 F five someone that's really going for it. 00:55.950 --> 00:57.540 White has that bishop pair. 00:58.020 --> 00:58.950 You might think. 00:58.950 --> 01:01.410 How come we're showing this from Black's perspective? 01:01.410 --> 01:05.070 Well, there's something very, very interesting which happens. 01:05.190 --> 01:07.350 F6 Rook have four. 01:07.350 --> 01:13.860 So White does seem to be putting all his pieces trying to put all these pieces around the King b5 rook 01:13.860 --> 01:18.030 H for Queen B six and now E5. 01:18.030 --> 01:24.270 So very aggressive looking play just to open up the bishop sacrifice sacrificing a pawn because of Knight 01:24.270 --> 01:27.630 takes E5 that is a pawn sac, but it has opened up the bishop. 01:27.870 --> 01:39.060 But now f takes e6 Knight 63 The Queen takes the place of the Bishop looking at H7 Queen St's e6 Queen 01:39.060 --> 01:42.720 St St seven, King of seven, Bishop h6. 01:42.720 --> 01:45.630 And here is the fame of Queen in Siberia. 01:45.630 --> 01:49.530 So this is a pattern I picked up from neural network games. 01:50.490 --> 01:56.940 And that's, you know, it kind of influences the structure of this course actually also form pawns. 01:56.940 --> 01:59.220 And I've made t shirts out of form pawns also. 01:59.220 --> 02:00.990 Bishop without a counterpart. 02:00.990 --> 02:10.500 But yeah, Queen in Siberia is another kind of pattern where pieces kind of get stuck away from activities. 02:10.500 --> 02:18.420 And there's a very lucrative move here that Max Auer played, which on a more detailed inspection, 02:18.420 --> 02:20.970 actually it does have a flaw. 02:22.320 --> 02:23.970 I don't mean I don't mean salary floor. 02:23.970 --> 02:26.550 I mean fe lw, not Salman flaw. 02:26.580 --> 02:27.360 It has a flaw. 02:27.390 --> 02:28.440 This next move. 02:28.440 --> 02:32.520 So what would you play here and why? 02:32.880 --> 02:34.500 For 200 points. 02:37.080 --> 02:38.850 So the Queen in Siberia. 02:38.880 --> 02:44.370 The Queen's not quite in Siberia because it's looking across the whole diagonal, which interferes with 02:44.370 --> 02:45.690 attacking potential. 02:49.690 --> 02:55.780 And I'm kind of misleading you of this, but it is it is based on what was played, but which might 02:55.780 --> 02:57.820 not actually be the strongest move. 03:02.090 --> 03:02.260 Okay. 03:02.420 --> 03:05.590 What was played seems absolutely visual, visually stunning. 03:05.600 --> 03:10.010 We have to give it that real catch, ain't it? 03:10.010 --> 03:12.380 Turns out this might not be correct. 03:12.500 --> 03:16.640 The correct way to play this might actually be Rook Frey, believe it or not. 03:17.930 --> 03:19.850 And this carries the threat of Rook. 03:19.850 --> 03:20.690 Thanks, Jeffrey. 03:20.690 --> 03:26.480 To puncture wounds control of the Air Force E for square for resources like this. 03:26.480 --> 03:34.460 So as example, if rook have one queen five this position. 03:37.310 --> 03:40.000 It's actually kind of interesting. 03:40.010 --> 03:42.080 It looks like crazy stuff. 03:42.080 --> 03:51.320 But here, for example, Rook C2 can happen and we get a possession which the black king kind of evacuates 03:51.320 --> 04:03.710 and there's a rook takes two punch here to puncture this diagonal and this position ends up being the 04:04.460 --> 04:06.260 same as of Queen G2 mating. 04:06.410 --> 04:10.460 But this position ends up being in Black's favor. 04:10.820 --> 04:16.370 Even though black is the exchange down, there's two pawns were being exchanged down, so that ends 04:16.370 --> 04:17.930 up being in Black's favor. 04:18.500 --> 04:21.770 So Rook C3 is actually a very interesting move. 04:24.500 --> 04:26.990 The thing is, so that's we've rook have won. 04:26.990 --> 04:29.780 We saw that with rook have one how that can work. 04:30.320 --> 04:42.320 But also if we look at the disruptive D5 here, Queen takes D5, there's no E4 but in this position. 04:43.460 --> 04:51.800 Queen D for check, King H H1 the Queen in Siberia effects can be felt with this move. 04:51.800 --> 04:58.880 Rook H ain't to put the Queen away from action and this is just very strong. 04:58.880 --> 05:02.240 If Queen takes her, Bishop takes E4. 05:04.270 --> 05:04.840 Rookie one. 05:04.840 --> 05:06.280 G tanks H six. 05:06.880 --> 05:10.180 This position planks doing really quite well. 05:10.690 --> 05:16.270 The king is not being the black king is not being mated and black is getting the advantage. 05:16.360 --> 05:17.890 If we look at this again. 05:20.430 --> 05:21.090 Here. 05:24.010 --> 05:27.160 So we're saying 94. 05:27.200 --> 05:28.380 24, Jack. 05:29.230 --> 05:29.620 Yeah. 05:29.620 --> 05:32.260 I mean, there's interesting variations. 05:32.980 --> 05:33.790 If. 05:36.570 --> 05:37.800 Rookie fall. 05:38.070 --> 05:40.050 Look at rookie for a moment. 05:43.940 --> 05:49.720 There's Bishop E for Queen Sexy for G tanks. 05:49.820 --> 05:51.740 This position has just been a blank. 05:52.190 --> 05:52.970 Yes. 05:53.330 --> 06:00.260 And if Knight takes it for her rook C4 rookie one queen G4. 06:03.500 --> 06:11.910 Brooke, I have one rule which is very useful here, to drag the queen kind of away from action to win 06:11.910 --> 06:12.870 the E4. 06:12.870 --> 06:20.100 So the rib Cage eight resource does feature actually in many of the technically absolutely winning variations. 06:20.160 --> 06:24.000 It's not a button to press to get the queen away from key squares. 06:24.900 --> 06:28.080 So yeah, Rook C free technically is the way to go. 06:28.110 --> 06:40.710 It seems as though, you know once in big trouble here whatever white done so you know rook f one is 06:40.710 --> 06:43.620 not working basically in a nutshell because of Queen D five. 06:43.620 --> 06:43.980 Yeah. 06:44.190 --> 06:45.360 So okay. 06:46.260 --> 06:54.150 But in the game we have the immediate rib cage eight based on the idea of being able to play Roxy to. 06:56.130 --> 07:03.880 Okay, So it looks as though this is a good queen in Siberia case, because surely Rook C, too, is 07:03.880 --> 07:05.320 absolutely winning, right? 07:05.830 --> 07:08.170 Because we're getting our teamwork. 07:08.170 --> 07:09.910 We're getting a killer common square on G2. 07:09.940 --> 07:11.620 Why isn't this absolutely winning? 07:12.610 --> 07:20.380 Okay, If Queen D five as an alternate, you know, rookie four was what is black do at five This rook 07:20.380 --> 07:25.600 have one so it has to be with rook c two. 07:25.600 --> 07:26.920 This is just hopeless. 07:27.940 --> 07:34.450 Basically four black black's getting on the losing end there, so Rook c two seems absolutely convincing, 07:34.450 --> 07:35.020 right? 07:37.630 --> 07:40.930 Well, it becomes convincing because white plays rook C one. 07:40.960 --> 07:42.550 This is actually a big mistake. 07:42.550 --> 07:55.870 Before we get into it, there's a resource here which is super annoying, and it tells us that as attacking 07:55.870 --> 08:01.480 players, the details, the finesses really, really matter. 08:01.480 --> 08:05.740 And this, this resource was only analysed after this game was played. 08:05.740 --> 08:11.230 It was researched, you know, even without engines, but they found this resource even when our engines 08:11.230 --> 08:17.350 eventually there's a resource here which can't see through this kind of killer common square business 08:18.100 --> 08:19.540 and that resource. 08:19.540 --> 08:21.310 I wonder if you can spot what it is. 08:24.350 --> 08:24.780 Okay. 08:24.850 --> 08:26.720 It's actually D5. 08:27.680 --> 08:30.590 So if Queen Tanks D5. 08:30.650 --> 08:38.420 The point is the bishops no longer looking at G2, so rookie for her and White's got the advantage. 08:40.430 --> 08:42.320 And also white is actually French. 08:42.320 --> 08:47.360 Then Queen 68 her, which is a mate prat. 08:47.480 --> 08:52.430 So if the rock scurries back, then White just builds up on it. 08:52.460 --> 08:53.370 Check here. 08:53.390 --> 08:54.710 Bishop e Fray. 08:54.920 --> 08:58.550 This is not going anywhere once getting a huge advantage. 08:59.150 --> 09:02.420 So, yes, this this is kind of problematic. 09:03.050 --> 09:10.350 And if Bishop takes D5, believe it or not, Rook D1 creates a kind of defensive square. 09:10.370 --> 09:12.260 Kill a defensive square. 09:12.890 --> 09:15.110 Kill a common square for D4. 09:15.320 --> 09:17.600 And the reason why that's important. 09:18.170 --> 09:20.000 That's the only move here. 09:20.420 --> 09:21.530 Rook D1. 09:22.070 --> 09:27.710 I mean, basically it's the only move because black currently is faster than Queen B6 check. 09:29.270 --> 09:31.370 And then, you know, Bishop takes G2. 09:31.370 --> 09:36.720 So for example, if one plays A4 as a token move just to show Queen B6 check. 09:36.740 --> 09:41.540 Bishop takes G2 is mating and if King F1 Queen F2 is mating. 09:41.540 --> 09:51.530 But this move is a right Payne rook D1 because it means that if Queen b6 check now there's rook d4 and 09:51.530 --> 09:54.440 how this black's attack continue. 09:54.470 --> 10:03.310 So yes, this position shows the details matter and actually y can unfortunately consolidate. 10:03.320 --> 10:09.080 You know for example this position check and then get the queen's off and what ends up with winning 10:09.080 --> 10:09.800 position. 10:10.880 --> 10:21.710 If Rook takes G2 instead of Queen B6, check king if one rook a2 Bishop D2 disconnects the rook from 10:21.710 --> 10:22.550 G2. 10:22.790 --> 10:31.140 This position white can counter sacrifice and we get a position where Queen h5 check. 10:31.160 --> 10:37.250 We get a position which is about even in this endgame, Black has enough pawns to actually claim equality. 10:37.610 --> 10:44.540 But yeah, it just shows the details in chess for the attacking player to factor in. 10:44.540 --> 10:45.890 This is a really subtle detail. 10:45.890 --> 10:51.740 One of the more subtle of all the games in this course, and yet it just shows that I would have loved 10:51.740 --> 10:56.800 to have shown a queen in Siberia theme from this position with the played move. 10:56.810 --> 11:04.010 But it turns out it is still a useful switch kind of to press a buttons press in some of the key variations 11:04.010 --> 11:05.000 that we witnessed. 11:05.000 --> 11:08.840 Just not here, just not in this exact position. 11:08.870 --> 11:11.070 That's the funny thing about chances. 11:11.070 --> 11:14.800 It's very, very difficult to estimate the resources. 11:14.810 --> 11:16.640 I mean, who would have for that move? 11:16.640 --> 11:20.630 Rook C Free is going to be so strong. 11:20.630 --> 11:22.400 So but yeah, it does. 11:22.400 --> 11:23.090 Frandsen. 11:23.090 --> 11:24.680 Rook Thanks, Geoffrey. 11:25.010 --> 11:28.820 To get into the E to square, which gets the coordination on G2. 11:29.150 --> 11:34.880 So yes, this is why, I mean, the D5 stuff doesn't work against Rook C3. 11:36.230 --> 11:42.080 So just to recap here, this doesn't work so well because Queen d4 Shank Rook h8 now. 11:43.030 --> 11:44.140 Is powerful. 11:44.860 --> 11:46.020 And the bishop, thanks for this. 11:46.060 --> 11:48.040 This is just a powerful position for blank. 11:48.220 --> 11:48.580 Yeah. 11:48.610 --> 11:49.660 Huge difference. 11:49.660 --> 11:51.300 The timing of Rook H eight. 11:52.270 --> 11:55.410 So in these variations, black ends up being better. 11:55.420 --> 11:56.500 So funny stuff. 11:56.500 --> 12:06.250 But rook out immediately queenside so white didn't see the D5 resource because White's human is don't 12:06.250 --> 12:07.960 stop fish supercomputer. 12:08.140 --> 12:10.000 So Rook C1 is played. 12:10.360 --> 12:11.050 Okay. 12:13.240 --> 12:20.590 And now we have we do have the queen in Siberia fame sure that the Queen is there on H8 in a silly possession 12:21.160 --> 12:24.060 and now a super accurate move is actually played here. 12:24.070 --> 12:30.490 One of the absolute the absolute best move it seems is played here from from Max. 12:30.510 --> 12:30.760 Okay. 12:30.790 --> 12:32.140 Can you see what that is? 12:34.270 --> 12:36.280 If I give you 5 seconds, pause in your hair. 12:40.160 --> 12:40.880 400 points. 12:40.880 --> 12:41.120 Yeah. 12:41.150 --> 12:41.900 Queen bee free. 12:41.930 --> 12:46.700 It does threaten to swoop in from be free to to the King position. 12:47.510 --> 12:50.660 So we have King E one queen every. 12:54.060 --> 13:04.830 Rookie full queen F to check and here Rook G one Shaq Knight f1 rookie STS f1 tank Rookie one Rook takes 13:04.950 --> 13:05.400 one. 13:05.520 --> 13:11.190 So at the game at the time of this game, this must have been entirely convincing this rookie eight 13:11.220 --> 13:17.750 leaving a vivid impression of how to kind of disable the opponent's queen to get a vicious attack. 13:17.760 --> 13:22.830 But yeah, details do matter and the stronger and stronger the opponent's. 13:22.830 --> 13:25.980 You get what I think of as scalability. 13:26.580 --> 13:30.030 You know, you need to have attacking chess with scalability. 13:30.660 --> 13:36.780 So yeah, there is a funny way of actually black black proving the advantage. 13:36.780 --> 13:44.610 So it's a funny game and clearly not a perfect queen in Siberia example. 13:45.300 --> 13:52.650 But we're playing against humans and we're only humans generally, so it's still interesting and it's 13:52.650 --> 13:54.720 still a celebrated game of Max. 13:54.720 --> 13:56.880 Oh, I really celebrate game. 13:56.880 --> 14:03.630 So it's giving credit to this world champion for this creative achievement. 14:04.920 --> 14:11.010 Flaws or not, it's still, you know, a brilliant game for that whole concept of dragging the queen 14:11.010 --> 14:17.220 right to the corner here to gain access to the C2 square, The principle remains sound. 14:17.220 --> 14:24.630 The philosophy remains sound of taking your opponent's pieces to obscure locations so you can get more 14:24.630 --> 14:27.900 influence on key attacking squares like C2. 14:27.900 --> 14:31.740 So the principle is there in this game for sure. 14:33.750 --> 14:34.650 Floor or not. 14:34.770 --> 14:36.990 Okay, I hope you enjoy that. 14:37.200 --> 14:37.890 That's a much.
