WEBVTT 00:01.170 --> 00:01.920 Hi there. 00:01.950 --> 00:08.160 In this lecture, we see Sigma Terrace playing against Alexander Alekhine in 1922 Bad Piston Tournament. 00:08.820 --> 00:11.070 So we see d4 from Tarrasch. 00:11.100 --> 00:16.170 Nice to have six from alekhine noit f3 e6 c4. 00:16.710 --> 00:25.140 And this looks like this is basically a queens Indian transposition for a slightly different move order 00:25.140 --> 00:26.820 with a free first. 00:27.120 --> 00:33.820 So queens Indian territory would be d4 of six usually c4 e6 and they'll have free. 00:33.840 --> 00:35.400 We have the same possession. 00:35.670 --> 00:41.560 So in this Queen's Indian move order we have alekhine playing C5. 00:41.580 --> 00:45.000 This spices things up after D5. 00:45.870 --> 00:50.190 One of the better options and this is according to modern engines, this is one of the better options 00:50.190 --> 00:51.100 to play this gambit. 00:51.120 --> 00:55.970 The Blumenfeld Gambit Blow me Blumenfeld Gambit. 00:55.980 --> 01:02.970 If he takes D5 instead, we could transpose into a modern Benoni position where Y hasn't got the option 01:02.970 --> 01:03.600 of F4. 01:03.630 --> 01:08.460 That is an interesting option, where the F4 option is sometimes critical. 01:08.490 --> 01:13.380 The fleck variation against the Benoni, for example, with F4 and Bishop B5 was very dangerous. 01:13.380 --> 01:15.510 So that is a plausible way of playing it. 01:15.510 --> 01:18.090 But this is really quite fascinating. 01:18.390 --> 01:23.330 This particular gambit example game is iconic to me actually. 01:23.340 --> 01:26.640 So we have D takes E6. 01:28.260 --> 01:43.440 If C tanks b5 e 65 Bishop g5 Bishop Be7 F3 a6 black tries to get some play and Bishop E7 is a move here 01:43.770 --> 01:46.180 where White would have to tread carefully. 01:46.200 --> 01:51.600 Bishop takes F6 seems to just lose the advantage this position with Bishop thanks B to black cats and 01:51.600 --> 01:56.880 play with Queen A5 Jack and taking out D5 here. 01:57.630 --> 02:03.180 This is leading to a situation which is, you know, a small edge for blacks. 02:03.180 --> 02:11.310 So instead of Bishop takes F6, this seems to be a bad idea in general to give up not quite Bishop A4 02:11.640 --> 02:14.820 and this position should be a small edge for white. 02:15.120 --> 02:20.460 But anyway, D takes E6 is actually more critical if it's followed up correctly. 02:20.940 --> 02:23.640 F4 takes E6 and this is quite fascinating. 02:23.910 --> 02:28.320 White grabs the B5 pawn and black plays D5. 02:30.050 --> 02:32.980 Now, why is this fascinating to me on a revisit? 02:32.990 --> 02:37.990 Well, I have more detailed knowledge about the move 93. 02:38.000 --> 02:43.730 And actually this is one case where 93 is a top like engine suggestion here. 02:44.120 --> 02:49.730 The thing is, Black's got this kind of ominous censor build up. 02:49.790 --> 02:57.350 If the light squares can be made more solid, black eventually could play for EA five, ea four and 02:57.560 --> 03:01.790 a kind of really strong attack potential from this position. 03:01.790 --> 03:07.420 So this has to be stopped early on right now. 03:07.640 --> 03:08.330 It really does. 03:08.330 --> 03:11.710 Otherwise Black just gets an advantage and won't play the passive move. 03:11.720 --> 03:21.320 E3 G4 is not much better because it takes this position that there is strong counterplay for black E5 03:21.320 --> 03:30.290 is possible and we get a situation where maybe 90 free here is still useful though for the advantage. 03:30.320 --> 03:37.730 93 does seem to be a key move because these pawns don't have many pawns supporting them behind them 03:37.730 --> 03:40.760 and it makes this kind of pressure more effective. 03:40.790 --> 03:49.990 If Bishop G5 let me just show you E4, this position should be about even, but with Knight C4 a flat 03:50.000 --> 03:54.530 place D for the light squares, you can see the light squares. 03:54.950 --> 03:58.730 This provoked provocation with the knight on C3 going to be five. 03:58.850 --> 04:01.820 This is just really interesting, this position. 04:04.240 --> 04:07.930 So, for example, Queen Bee six, Queen Bee three. 04:08.620 --> 04:11.290 You know, this is this is problematic for black. 04:12.790 --> 04:14.590 These stories are problematic. 04:14.590 --> 04:24.040 And otherwise, it's interesting that black is in positional trouble here. 04:24.250 --> 04:27.070 Of the bishop D2 in a sense. 04:27.860 --> 04:28.810 Okay, so. 04:30.010 --> 04:37.220 But even better than all this from the outset here, instead of certainly instead of E3, there is Nike 04:37.240 --> 04:44.620 free, which is a super good move, it turns out here, because if the bishop can come out later to 04:44.620 --> 04:49.610 C4, it's really eyeing a lot of issues here. 04:49.630 --> 04:57.040 So as an example, if Bishop E7, E4, if E4 there's A4 job done because the light squares have been 04:57.040 --> 05:00.970 weakened and these pawns are kind of fragile, this is an ideal position. 05:00.970 --> 05:10.380 Even if E4 drops here, giving back one pawn, one establishes light square control on various light 05:10.420 --> 05:10.840 squares. 05:10.840 --> 05:16.120 And this is, this is to me, the White's plan for an advantage, which is why perhaps, you know, 05:16.150 --> 05:19.720 the Bloomfield gambit is not entirely great. 05:19.720 --> 05:22.930 It does seem like C4 is an absolutely critical test. 05:23.050 --> 05:27.370 If if Bishop seven e4 default. 05:27.370 --> 05:30.040 Yeah, this does seem a critical test. 05:30.250 --> 05:37.120 But also let's imagine de takes. 05:37.120 --> 05:43.540 We can just take the queen off, Queen's off and then Knight G five is nice. 05:43.540 --> 05:44.290 It's going to be nice. 05:44.290 --> 05:46.990 It's a position you're hitting E6 and E4. 05:47.110 --> 05:51.580 Yeah, there's a lot of compensation here and. 05:52.720 --> 05:53.020 Yeah. 05:53.020 --> 06:00.940 So d for a for this position, it's just good for Wayne to get that grip so nicely. 06:00.940 --> 06:03.040 Free is a key move to be aware of. 06:06.580 --> 06:15.220 If Bishop de sex e for de tax night g five hare Bishop C for and then the gambit doesn't look so hot 06:15.640 --> 06:16.480 but in the game. 06:16.480 --> 06:26.350 Yeah we do get a kind of real downside now of E3 it's so passive this position of the bishop 8693 Black 06:26.350 --> 06:36.490 Castles Bishop Ito bishop b7 the grip is intensifying on the center now be free is played if castling 06:36.490 --> 06:45.370 Han Knight b seven a4 this position 8588 it might be imbalanced, but it's easier for black to play 06:45.370 --> 06:45.730 this. 06:45.730 --> 06:48.550 There are fans turning up like E5 and E4. 06:50.260 --> 06:55.750 Instead of be free hair if your hair is interesting. 06:55.960 --> 06:59.320 So E takes e takes, but black stands better. 06:59.500 --> 07:03.160 There's no -- of the light squares just yet. 07:03.190 --> 07:10.150 And black has attacking prospects here and may even just pivot the queen at some point to the kingside 07:11.350 --> 07:15.490 and with D4 ominously looking at G2. 07:16.510 --> 07:18.970 Yeah, this is absolutely fascinating stuff. 07:19.930 --> 07:22.450 If we go back here. 07:27.680 --> 07:28.520 And. 07:30.090 --> 07:37.440 So the suggestion that be free looks passive by E4 looks plausible if DD takes e4 again. 07:37.440 --> 07:46.410 Knight Ji five familiar patterns say Bishop D5 to try and keep things intact to some extent and potentially 07:46.410 --> 07:47.950 offering an exchange sack. 07:47.970 --> 07:50.490 This is fine here. 07:50.820 --> 07:53.100 1965 it takes. 07:54.850 --> 07:58.330 It's fine for Y actually, because of 96 just winning the exchange. 07:58.360 --> 07:59.500 The thing is. 07:59.500 --> 08:04.000 Yeah, so black can't really keep things intact and this is precarious. 08:04.030 --> 08:08.360 After 1965, if H takes G five, then Knight takes f6. 08:08.380 --> 08:15.640 The Queen as Queen takes the queen, takes d6, rook takes less, Bishop takes G five and G takes looks 08:15.640 --> 08:19.030 wretched with Bishop C four and Queen G four. 08:19.060 --> 08:19.990 This looks painful. 08:20.020 --> 08:20.590 Black. 08:20.710 --> 08:26.740 So in other words, yeah, it seems as though b4 is also a pretty passive move. 08:26.920 --> 08:32.710 E4 to try and challenge black on the light squares. 08:32.710 --> 08:39.520 Seems important here, but yeah, black can just play. 08:40.390 --> 08:41.920 Might be the seven at this point. 08:41.920 --> 08:43.630 It's a bit too late. 08:44.170 --> 08:47.140 This just in time controls the E5 square D5 is intact. 08:47.170 --> 08:49.270 It's a little bit too late, but it had to be tried. 08:49.270 --> 08:52.090 So we really get yet another passive move. 08:52.120 --> 08:53.380 Night bd7. 08:53.380 --> 08:54.040 Bishop B two. 08:54.040 --> 08:54.910 Queen D seven. 08:54.910 --> 08:58.300 This is a train position basically. 08:58.300 --> 09:03.760 So one would think the Blumenfeld gambit is like a win by forcing this game. 09:03.760 --> 09:05.290 Basically Queen C to E5. 09:05.290 --> 09:09.960 It looks as though hold on, the Knights Knight's being driven away from H to this. 09:09.970 --> 09:12.070 This is like what is going on here? 09:12.070 --> 09:13.000 What does white done? 09:13.000 --> 09:18.220 Rook f one is played if e4 here it's a bit too late. 09:18.220 --> 09:20.590 D4 and Bishop takes e4. 09:20.920 --> 09:22.210 Simple enough. 09:23.590 --> 09:24.880 Is pretty nasty. 09:25.060 --> 09:27.910 And if, Bishop, if we can just take in an E for. 09:30.150 --> 09:32.340 This is this is nasty, basically. 09:32.550 --> 09:33.660 It's too late. 09:33.660 --> 09:35.580 It's too little too late. 09:35.700 --> 09:39.120 So, rook f1 e4, this is just an absolute dream. 09:39.510 --> 09:42.930 Position 9591. 09:42.930 --> 09:49.140 And now looking directly at soft spots like age two, now we have Bishop takes G4, which weakens light 09:49.140 --> 09:49.730 squares. 09:49.740 --> 09:52.260 So still looking at age to not have one. 09:52.260 --> 09:52.770 And now. 09:52.770 --> 09:55.710 Yeah, direct kind of attack is justified. 09:55.730 --> 09:57.900 Queen five This is what I mean. 09:57.900 --> 10:03.930 It's like an iconic gambit game and if you don't know how to handle the white pieces with an early nine 10:03.930 --> 10:07.980 C for an E4, you get his passive position. 10:07.980 --> 10:09.690 It looks like a loss by default. 10:09.720 --> 10:12.750 86928619 and five. 10:12.750 --> 10:20.070 It's just a vicious position with got having limited counterplay nice H2 and now D4 trying to open up 10:20.070 --> 10:21.150 this bishop to G2. 10:21.180 --> 10:25.620 This looks like you know it's a very very dangerous bishop lurking here for attack. 10:25.830 --> 10:35.430 We have Bishop C1 if a free bishop d5 this position of pull wedge there in the center is going to be 10:35.430 --> 10:35.760 nice. 10:35.760 --> 10:44.250 Bishop 6h2, Knight H four and we can even have this rawcliffe This extra space means these rook lifts 10:44.250 --> 10:47.640 are amazing and this position is just crushing. 10:47.910 --> 10:51.350 So Bishop C1 is like the free hair similar to the game. 10:51.420 --> 10:57.120 Queens D Fortnite, King H, eight, Bishop B2 and Knight, Geoffrey Shaq. 10:57.210 --> 10:58.590 This can't be taken. 10:58.590 --> 11:02.280 King G one If F takes G a queen takes G3. 11:03.090 --> 11:06.630 Once in huge trouble here, as you might suspect. 11:06.630 --> 11:07.200 If not, have fun. 11:07.200 --> 11:08.580 We're just snapping that off. 11:08.580 --> 11:10.530 And then Queen H two is checkmate. 11:11.610 --> 11:14.490 Yeah, it's huge trouble here. 11:15.120 --> 11:16.920 So King G1 was right. 11:17.280 --> 11:21.540 Bishop D5 and we have Queen A4 So Y has been reduced. 11:21.540 --> 11:24.480 I mean, these are disconnected rooks on t one. 11:24.480 --> 11:27.330 Why is reduced to trying to win a seven? 11:27.330 --> 11:35.010 I mean really we have 92 King H one If Rook takes E2, that doesn't give much relief that tanks and 11:35.010 --> 11:43.650 I'm Bishop takes H two rook takes F2 and this is over because E1 distracting the rook mate so King H 11:43.650 --> 11:48.690 one is played rook f seven okay protecting A7 for a moment. 11:48.690 --> 11:56.280 Queen A6 Just trying to be a nuisance H five that stops any back road trips, tricks, tricks and stops 11:56.280 --> 11:59.670 doing g4 b six here just being a nuisance. 11:59.670 --> 12:04.410 But in fact even this queen is a potential, it's a potential downside. 12:04.410 --> 12:05.790 It's an unprotected piece. 12:05.790 --> 12:07.020 Bear that in mind. 12:07.020 --> 12:12.210 We have Knight G free choke here King g18 takes queen takes B6. 12:12.210 --> 12:14.430 So that's an unprotected piece liability. 12:14.430 --> 12:20.640 We have 90 to check the queen just happens to support D eight. 12:21.300 --> 12:28.980 Okay so King h19g free check King G one and now D2, this forcibly wins the exchange. 12:28.980 --> 12:30.120 Where is the rook going? 12:30.120 --> 12:38.200 So rook have 196f196f1 and now Bishop e6 gunning H three. 12:38.310 --> 12:41.100 Yeah, it's just the dream attacking flow game. 12:41.640 --> 12:45.090 King H one And now guess what Alekhine plays here. 12:45.510 --> 12:50.460 Which exposes the king essentially for ten points. 12:52.090 --> 12:52.290 Yeah. 12:52.300 --> 12:53.210 Just chips away. 12:53.230 --> 12:56.590 Bishop takes H for G, takes Rook every night. 12:56.590 --> 12:59.020 g3h for. 12:59.020 --> 13:01.180 Yeah, it looks absolutely terrible. 13:01.180 --> 13:07.390 Now, of course, Bishop f6, this is a very desperate move for a very desperate tactic. 13:07.510 --> 13:08.380 So. 13:08.920 --> 13:16.060 Okay, the thing is, if Knight if one does, Rook takes h free check and then just mating. 13:16.060 --> 13:18.880 So Bishop f6 we have queen size. 13:18.880 --> 13:19.390 Sure. 13:19.390 --> 13:25.000 If G takes that blocks the support of D eight queen. 13:25.000 --> 13:27.060 Thanks D but that's black. 13:27.100 --> 13:28.450 Doesn't need to do this. 13:28.840 --> 13:36.340 We have just queen size f6 allowing 94 nine takes E4 because now rook takes H three and one has to resign 13:36.340 --> 13:36.880 here. 13:37.480 --> 13:42.610 If King G2, Queen Africa and Rook H one or Queen H one is mating. 13:43.060 --> 13:49.690 If King G won, we have a wealth of options here. 13:49.960 --> 13:56.230 But the Queen, we can actually backfire things against the Queen here with Bishop H to check to win 13:56.230 --> 13:56.980 the Queen. 13:57.670 --> 13:58.180 Yeah. 13:58.210 --> 13:59.260 Funny stuff. 13:59.830 --> 14:06.700 It's important to understand this game is not supposed to get a winning attacking position by force. 14:06.700 --> 14:14.800 That's why I'm at Labour to show some enthusiasm here for an early night c free concept. 14:15.010 --> 14:19.120 So if you ever have this, the white pieces are pretty worried about this. 14:20.170 --> 14:28.330 And I have been in the past, it seems nicely phrased an instrumental move to try and pierce open prise, 14:28.330 --> 14:35.890 open light squares in Black's camp in various ways, either through force of E4 or provocation of default. 14:35.890 --> 14:40.450 Whatever happens, if the D4 pawn moves, you know, opens up like squares. 14:40.450 --> 14:44.110 Black's structure is kind of fragile here. 14:44.110 --> 14:46.120 It's up to pieces to support it. 14:46.120 --> 14:49.450 There's no kind of pawn supporting, for example, C5. 14:50.230 --> 14:54.250 But yeah, the way it was played is an absolute dream come true. 14:55.090 --> 14:57.260 So in the actual game, that's a variation on me. 14:57.280 --> 15:01.240 In the actual game, it's an absolute dream come true because of E3. 15:01.240 --> 15:06.760 This is just it looks like for me such a smooth attacking win. 15:06.970 --> 15:13.420 But yeah, if you have this attacking position here, yeah, it's just a dream come true for the attacking 15:13.420 --> 15:16.090 player, but it's just not guaranteed. 15:16.330 --> 15:21.220 So just bear that in mind if you are considering this Blumenfeld gambit because you might be a Nimzowitsch 15:21.220 --> 15:22.210 engine fan. 15:22.210 --> 15:27.550 So obviously it becomes like a model game, this position. 15:27.550 --> 15:33.130 So C5 with the idea of B5, it is really interesting and maybe at the faster time because you can have 15:33.130 --> 15:34.750 a great deal of fun with this. 15:35.200 --> 15:37.330 Okay, so much.
