WEBVTT 00:00.950 --> 00:01.910 Hi there. 00:02.240 --> 00:04.850 In this, actually, we see the so called game of the century. 00:04.850 --> 00:09.440 This is Donald Byrne against Bobby Fischer in 1956. 00:09.530 --> 00:12.560 Third was Maude Trophy, round eight. 00:13.010 --> 00:23.120 So Byrne had won the US Open Championship in 1953 and had achieved the second highest rating in the 00:23.120 --> 00:29.840 US behind Sammy Rose FC, against whom Byrne had a winning record. 00:30.770 --> 00:35.870 So this is a very strong opponent that the young Bobby Fischer is facing. 00:35.870 --> 00:37.760 Nights of free is played. 00:38.120 --> 00:47.360 We have Knights of six from Fischer, C4 g6, C free, Bishop G seven D4 black consoles. 00:48.260 --> 00:50.950 We have Bishop F4 and now D5. 00:50.960 --> 00:53.030 So this is now Grunfeld territory. 00:53.390 --> 00:59.990 The Russian system Queen B3 detailed C4 is played. 01:02.120 --> 01:03.680 C-5 is another option here. 01:03.710 --> 01:05.870 This is interesting. 01:07.250 --> 01:13.280 And we get a game where like, should be fine. 01:14.300 --> 01:18.290 So C5, Yeah, there's lots of possibilities, but let's look at the game. 01:18.440 --> 01:19.730 Now do you take C4? 01:19.730 --> 01:22.400 Queen takes C4 C6. 01:24.240 --> 01:32.000 We have e4 Bd7 Rook D1 so it looks as though White's plan is pretty sensible. 01:32.010 --> 01:32.790 Logical. 01:34.860 --> 01:37.500 Fair is also a move here. 01:38.130 --> 01:43.680 So, for example, the bishop could take away on age to why it should be with a small armchair. 01:44.130 --> 01:53.970 So rugby one though we have might be six Queen C five Bishop G4 and now you have the king still in the 01:53.970 --> 01:54.750 center. 01:54.990 --> 01:58.560 And usually you want development to be optimal. 01:58.560 --> 02:02.100 You don't want to move a piece twice. 02:03.140 --> 02:04.340 In the opening. 02:04.430 --> 02:09.200 Otherwise you are asking for a little bit of trouble and a piece is moved twice. 02:09.200 --> 02:10.940 Bishop G5 is played. 02:12.800 --> 02:15.620 Bishop E2 would have been more solid. 02:16.400 --> 02:27.650 And for example, if Bishop thinks that Frank Bishop takes a free 57, hits the Queen, and if E5 this 02:27.650 --> 02:33.020 should be okay for whites, but hasn't done too much wrong actually. 02:33.410 --> 02:38.870 So this position should lead to a small edge for whites. 02:39.650 --> 02:41.630 So Bishop Ito wants to be preferred. 02:41.630 --> 02:45.170 So what happens after Bishop do you find now, which is so bad? 02:45.170 --> 02:46.580 Is it really that bad? 02:47.030 --> 02:56.030 Well, there's a very, very interesting move played here. 02:57.800 --> 02:59.810 Indeed, a brilliant move. 02:59.930 --> 03:01.640 Absolutely brilliant move is played here. 03:01.640 --> 03:04.070 I wonder if you can spot it for 500 points. 03:05.300 --> 03:06.590 Yeah, it's. 03:08.780 --> 03:14.870 Making use actually in some may of the bishop on G5 actually as a potential liability. 03:15.740 --> 03:19.280 It's like looking at the opponent's position and looking for liabilities balances. 03:19.280 --> 03:21.620 So there's a forcing of a fall. 03:21.890 --> 03:29.060 So hitting the Queen and trying to deflect this knight from E4, which creates a kind of chain reaction, 03:29.210 --> 03:31.460 you know, hitting the queen and the bishop. 03:31.460 --> 03:33.620 And then the bishop takes, the knight takes. 03:33.860 --> 03:36.110 So it's a chain reaction move. 03:36.120 --> 03:40.640 Knight A4 quite a brilliant move indeed. 03:40.910 --> 03:47.780 If h6 if a plain vanilla move has been played, this position is just even. 03:47.780 --> 03:48.490 It gives one. 03:48.530 --> 03:53.270 Maybe what they wanted a bit of weakness provocation, weaknesses on line squares. 03:54.140 --> 04:01.460 So you know, if the bishop goes back here again this is kind of even so. 04:02.230 --> 04:02.920 Yeah. 04:04.340 --> 04:06.380 So 94 is very interesting. 04:06.380 --> 04:08.210 So we have Queen A three. 04:09.080 --> 04:11.830 Believe it or not, if Knight takes a four. 04:11.840 --> 04:13.040 So let's have a look now. 04:13.070 --> 04:15.800 Knight takes it for that weakness for the last move. 04:16.850 --> 04:21.700 If Bishop takes E7, the thing is, this is opening up a file to the king. 04:21.710 --> 04:23.720 In effect, the king still in the center. 04:24.200 --> 04:27.470 So this is a great punishment of the king in the sense of this variation. 04:28.760 --> 04:33.260 Queen C seven is very strong here. 04:37.330 --> 04:42.370 Now there's no time for the bishop to take the role because the nine times queen and queen, a free 04:42.370 --> 04:43.480 rookie ain't. 04:43.750 --> 04:44.980 You can see that, actually. 04:45.010 --> 04:45.510 Hang on. 04:45.520 --> 04:51.640 There's a huge backfire now night G3 shack taking away each one black has a huge advantage. 04:52.180 --> 04:54.250 So, yes, this is very interesting. 04:54.580 --> 04:56.620 So Bishop takes E7 is not good. 04:56.620 --> 04:59.770 Queen takes E7, there's Knight takes G5. 05:00.340 --> 05:02.530 This position only takes the eight. 05:02.680 --> 05:09.360 And here Roc-A-Fella Check Bishop 61. 05:09.370 --> 05:11.680 This is very unpleasant things are falling off. 05:12.280 --> 05:17.080 So yes that justifies that that king of the center is a real liability. 05:17.680 --> 05:18.520 So. 05:20.070 --> 05:25.080 Okay, so perhaps why is Queen a free that's played instead? 05:25.890 --> 05:29.610 It seems now Knight takes Siegfried, so this is a bit counterintuitive. 05:29.910 --> 05:37.410 It seems to be strengthening the white centre, but it's still fragile. 05:37.410 --> 05:39.320 It's fundamentally fragile. 05:39.360 --> 05:40.230 The centre. 05:40.260 --> 05:48.330 If Queen St Siegfried has nine takes E4, and here Bishop takes her three G tanks, Queen A five. 05:48.330 --> 05:51.060 Jack So we're looking at G five. 05:51.240 --> 05:57.960 Bishop D2 1962, Queen St D2 as example, Queen size eight two and Black's doing really well. 05:57.960 --> 06:00.240 This is absolutely a shattered pawn structure. 06:01.620 --> 06:15.960 So B take C three is played and we have no tanks E4 here inviting Bishop tanks E seven If Bishop E2 06:17.430 --> 06:23.960 1965 1965 Bishop takes E2, King takes E2. 06:23.970 --> 06:31.320 There's a strong E5 hitting the knight and here he takes D4. 06:31.320 --> 06:32.910 Black's got a big advantage here. 06:34.020 --> 06:41.040 Oh, well, well, okay, so Bishop takes E seven is played and now. 06:41.070 --> 06:43.290 Yeah, this is an absolutely brilliant point. 06:43.290 --> 06:46.980 Fish is basically factoring in all angles to the king. 06:47.190 --> 06:47.910 Like this angle. 06:47.910 --> 06:48.780 This angle. 06:48.990 --> 06:51.000 And he plays actually Queen B six. 06:52.920 --> 06:54.780 Now Bishop C4 is played here. 06:55.590 --> 06:57.390 If Bishop takes a fight. 06:57.810 --> 07:06.000 The issue is the remarkable bishop takes a fight here because can you see a tactic in this position? 07:08.260 --> 07:11.950 Which is gaining even more material. 07:12.340 --> 07:13.960 For 100 points, what would you play here? 07:14.170 --> 07:15.460 So the king is in the center. 07:15.460 --> 07:20.920 So there are all these like roads that are king diagonals, diagonals of death, roads of death, you 07:20.920 --> 07:22.480 know, straight through roads. 07:22.480 --> 07:23.470 There's nothing to see. 07:23.470 --> 07:25.540 Free to try and get in bishop before. 07:26.290 --> 07:30.040 So here, Queen Saint Siegfried as bishop before pinning the queen to the king. 07:30.310 --> 07:36.430 And if queen thinks that's got more than enough material, this pawn on a two is going to be taken soon. 07:36.430 --> 07:43.390 So taking that with check this position huge advantage for why an African drop D4 is going to drop. 07:43.560 --> 07:50.380 It's just so much and it would have three connected pass pawns you know potentially so. 07:50.980 --> 07:58.540 Bishop C4 is tried not bishop takes her fight not this not entertaining this kind of rebounds on this 07:58.540 --> 08:09.580 diagonal we have now though a brutal move you know Knight take C free and I want choice to keep control 08:09.580 --> 08:10.730 of Bishop C5. 08:10.750 --> 08:17.200 If Queen St C3 then this bishop gets pinned and this is just great for black. 08:17.740 --> 08:19.500 If Bishop takes a fight. 08:19.690 --> 08:23.890 We're back to variations involving this horrible diagonal. 08:24.250 --> 08:26.860 So Queen C one we can actually take on D one. 08:26.860 --> 08:28.240 Here, check. 08:28.810 --> 08:30.100 Take out the bishop. 08:30.950 --> 08:33.220 Okay, so Bishop C five was tried. 08:33.730 --> 08:34.690 Rook f eight. 08:34.690 --> 08:36.880 Check King F one. 08:38.710 --> 08:40.900 Now, here, the king's on F one. 08:40.900 --> 08:41.500 Right? 08:42.190 --> 08:44.170 And it's good, actually. 08:44.350 --> 08:48.730 And I think this is a mistake I've been making, thinking there's only just one diagonal of death, 08:48.970 --> 08:49.240 though. 08:49.240 --> 08:53.830 Look out for the diagonals, plural of death where the king is. 08:53.830 --> 08:55.870 So where is the opponent's king? 08:56.740 --> 08:57.880 It's on F1. 08:57.880 --> 09:01.960 The theoretical diagonals of death, which we'd relish are these two. 09:01.960 --> 09:07.330 Now we have to look where the opponent's king is and look at the diagonals, plural of death. 09:07.330 --> 09:14.920 And you might have a clue then, for this next move based on this principle of diagonals, plural of 09:14.920 --> 09:15.460 death. 09:17.050 --> 09:19.540 So I arrived around the default diagonal. 09:19.540 --> 09:21.910 When you're white and you have the default thing or black. 09:21.910 --> 09:22.960 Yeah, I've won so many games. 09:22.960 --> 09:27.820 But also, yeah, it depends where the king is and when you know when the king is on the queen side, 09:27.820 --> 09:29.890 it's not just, you know, this diagonal. 09:30.220 --> 09:33.760 If the king is on this diagonal, but we have a king on F one. 09:33.760 --> 09:40.780 So we got to think in a theoretical sense because there's a there's a close relationship between theoretical 09:40.780 --> 09:44.920 downsides and technical variations. 09:44.920 --> 09:48.970 There's often a close relationship, especially in features games. 09:49.240 --> 09:54.160 So the King's on F1 is prone to a diagonal attack in theory. 09:54.670 --> 09:57.430 But how would we do that in practice here? 09:57.430 --> 10:03.670 It's a beautiful move indeed, based on, you know, diagonals of death is the ingredient, basically. 10:04.060 --> 10:07.480 So what would you play here for 200 points? 10:08.740 --> 10:11.230 So bear that in mind where the opponent's king is. 10:11.230 --> 10:13.360 Look at the diagonals. 10:14.080 --> 10:14.800 Okay. 10:14.830 --> 10:16.480 Instead of moving the queen. 10:18.070 --> 10:28.480 Absolutely brilliant move entertained bishop he sex ed Fisher just moved the Queen Queen St S.C. free 10:29.320 --> 10:33.640 and how does black actually attack white hair? 10:37.440 --> 10:41.880 If Be6 Bishop a3 c5 h3. 10:42.270 --> 10:44.460 Bishop Thanks d for this position. 10:45.120 --> 10:45.720 Bishop Thanks. 10:45.720 --> 10:47.550 D One Knight goes back. 10:49.730 --> 10:55.130 And you know why it has to bishops here for this friends might as well. 10:55.580 --> 10:57.680 So that would actually win material. 10:57.680 --> 11:02.490 You know, Queenie, y ends up being a bishop potentially. 11:02.510 --> 11:03.170 Ouch. 11:04.520 --> 11:05.630 So Queen C seven. 11:05.630 --> 11:06.070 Yeah. 11:06.080 --> 11:10.280 You know, I mean, most normal players have that natural reaction to move their queen. 11:10.280 --> 11:14.070 But this is absolutely brilliant based on diagonals of death. 11:14.090 --> 11:17.420 I know this one is closed up, but you can imagine, you know, sometimes there might be ten six on 11:17.420 --> 11:18.560 this diagonal. 11:18.560 --> 11:25.730 So Bishop e six was played offering, you know, a queen sacrifice. 11:25.730 --> 11:28.730 And the thing is, so Bishop takes be six was played. 11:28.730 --> 11:31.730 If Bishop takes E6, we still get onto this diagonal. 11:31.760 --> 11:33.050 There's a weakness of the last move. 11:33.050 --> 11:35.060 We pounce with the key square B five. 11:35.060 --> 11:43.310 Not a six of course, but B five gets onto that diagonal and would create a lovely mating pattern. 11:44.060 --> 11:45.650 So here, double check. 11:45.650 --> 11:49.130 And I hope you can see what Black would play here for ten points. 11:51.490 --> 11:54.640 Yeah, Queen F1, Shaq and that would be made there. 11:56.470 --> 12:00.070 And also, if we look at this, a sort of bishop takes these things. 12:02.050 --> 12:03.850 If you look at Bishop, be free. 12:05.560 --> 12:08.290 We still get onto the diagonal Queen B five, Jack. 12:08.430 --> 12:10.000 Yeah, it doesn't make any difference at all. 12:10.180 --> 12:12.220 We still the key thing is to get onto that diagonal. 12:12.220 --> 12:12.640 So. 12:12.640 --> 12:20.020 So the queen sacrifice is actually taken and Bishop takes C4 check now and we have a windmill kind of 12:20.020 --> 12:21.940 set of checks winning material. 12:21.940 --> 12:26.290 So check, winning D fall check. 12:27.370 --> 12:28.240 Check. 12:29.410 --> 12:36.160 And now it takes be six, delaying the check for a moment to win until to hit the queen. 12:37.540 --> 12:38.410 Queen before. 12:38.410 --> 12:41.200 And now another powerful forcing move here. 12:41.230 --> 12:47.970 These forcing moves are very, very useful for the attacking player whilst the king and the said just 12:47.980 --> 12:48.580 asleep. 12:48.580 --> 12:53.380 So the forcing moves are really good to keep the options limited. 12:53.380 --> 12:58.990 So offering a performance was only part of the double pawns anyway, but now winning this role. 12:58.990 --> 13:06.400 So a lot of material has been gains for the Queen sacrifice and each free rook takes a two. 13:06.580 --> 13:14.440 And now looking at F2 that's taken so lots of pawns, three pawns up loads of material for the Queen 13:16.270 --> 13:17.170 Rook and two bishops. 13:17.170 --> 13:24.640 Basically, if we refactor out rook and night for rook and knight, we're left with rook and two bishops 13:25.780 --> 13:26.470 against the Queen. 13:26.470 --> 13:28.420 But we've also got an extra three pawns. 13:28.420 --> 13:32.680 We have rookie one pair of rooks come off Queen the shank. 13:32.770 --> 13:37.540 Well insert in that first Bishop D5. 13:37.630 --> 13:41.770 So common targets like G2 now like 394. 13:41.800 --> 13:44.500 So if the king moves, there's Bishop D6 check. 13:46.180 --> 13:48.340 We have Queen B five. 13:51.810 --> 13:57.090 So all the pawns of the offended flank we have now h5. 13:58.920 --> 14:04.020 It's a huge possession, 95 and now underpinning tactic to liberate the bishop. 14:04.020 --> 14:05.610 Frightening bishop these CINCs. 14:05.910 --> 14:11.190 King G one But now Bishop C five Jack King have won. 14:11.190 --> 14:19.230 And now this beautiful walk over to the other side of the board, driven by the pieces by force or forcing 14:19.230 --> 14:22.680 moves 90 to check 90 C Free check. 14:22.680 --> 14:23.430 Very good sport. 14:23.430 --> 14:28.770 Donald Byrne allowing to be checkmated and it was Queen's game of the century. 14:29.640 --> 14:34.260 So the 13 year old future world chess champion Bobby Fischer against Donald Byrne. 14:34.710 --> 14:35.280 Yep. 14:35.280 --> 14:41.790 By Hans Mock in basically in 1956 Chess Review. 14:41.820 --> 14:49.830 Hans Mock dubbed it Game of the Century, a masterpiece of combination play performed by Boy at 13 against 14:49.830 --> 14:56.490 a formidable opponent, maybe the finest on record in the history of chess prodigies. 14:57.480 --> 15:04.740 It is beautiful, and it amply demonstrates that if the king is left in the center with the opponent 15:05.040 --> 15:12.480 being suboptimal in development, there are amazing resources on the chessboard. 15:12.810 --> 15:18.720 But yeah, what an amazing set of resources demonstrated by the young Fischer starting off with the 15:18.720 --> 15:20.310 amazing night A Fall. 15:24.290 --> 15:26.170 It's just incredible, really. 15:26.180 --> 15:32.750 And then strength in the sense only to think about obliterating it from all angles for that access path 15:32.750 --> 15:34.910 in mind in some of the variations already. 15:36.200 --> 15:43.130 So here, the idea of offering an exchange sacrifice to obliterate this diagonal and then the diagonals 15:43.130 --> 15:44.880 are still carefully watched by Fisher. 15:44.900 --> 15:48.380 The king has got two new diagonals because it's just moved. 15:48.980 --> 15:54.740 So there's stunning Queen sack trying to get onto this diagonal to get that check, which leads to a 15:54.740 --> 15:57.890 windmill to take winning a ton of material here. 15:58.850 --> 16:06.470 So taking out the centre, taking out the bishop, taking out the rook, and then just mass piece coordination 16:06.470 --> 16:11.840 resulting absolutely beautiful masterpiece, a treasure in chess history. 16:11.840 --> 16:13.550 I'm pinning for Bishop d6. 16:14.330 --> 16:21.980 So and then the king just taken from one end of the board to the other by force basically masterpiece. 16:22.130 --> 16:25.940 I hope you enjoyed this one and got some instructive lessons and why. 16:25.940 --> 16:31.010 You know, it's important sometimes not to move a piece twice in the opening of the Kingston in the 16:31.010 --> 16:33.980 sense there could be drastic punishments available. 16:34.430 --> 16:35.270 Okay. 16:35.660 --> 16:36.560 And so much.
