WEBVTT 00:01.290 --> 00:02.040 Hi there. 00:02.070 --> 00:05.340 In this lecture, we see Alexander Alekhine playing against Samuel. 00:05.340 --> 00:06.690 Samuel Reshevsky. 00:06.720 --> 00:08.340 This is in 1937. 00:08.340 --> 00:10.050 The camera is almost around eight. 00:10.620 --> 00:13.890 So E4 from Alekhine we have to have sex. 00:13.890 --> 00:18.780 So the Alekhine's defense being played against Reshevsky against Alekhine himself. 00:18.780 --> 00:29.970 So e5 95 D 46 nine to have three Bishop g4 we have C4 96 and now Bishop E two. 00:30.000 --> 00:32.160 So this is an interesting line. 00:32.280 --> 00:38.880 Quite often e tanks D Sex is played here, so this position is thought to be a small edge for white, 00:38.880 --> 00:39.270 but. 00:39.270 --> 00:44.880 Bishop E Yes, something interesting is about to happen in the opening of de5. 00:44.880 --> 00:50.340 Now Alekhine has actually created a gambit situation, basically. 00:50.370 --> 00:52.050 Guess what he plays here. 00:54.700 --> 00:55.210 Yeah. 00:56.300 --> 00:57.480 Knight takes E five. 00:57.500 --> 01:01.250 He's prepared to create a -- game out of the D for --. 01:01.280 --> 01:03.350 This is absolutely fascinating stuff. 01:06.330 --> 01:06.660 Yeah. 01:06.660 --> 01:11.550 So I mean, if de takes E5, then the queens just come off. 01:11.550 --> 01:12.840 It's not so great. 01:12.840 --> 01:17.130 There's not going to be too many attacking prospects and also see falls on the fire here as well. 01:17.130 --> 01:25.050 So is the king going to take you know it's miserable black to play 96 and Castle Queenside, etc. So 01:25.410 --> 01:31.350 Knight takes is a pawn sacrifice after Bishop takes it to the queen tanks. 01:31.350 --> 01:33.420 So allowing the D4 pawn to drop. 01:33.540 --> 01:37.560 So for this pawn there's a lot of pressure handed, some tempo gaining. 01:38.250 --> 01:40.380 So this is quite a fun position. 01:40.500 --> 01:56.970 White Castles Knights 8 to 37 and we see here 19 tasty seven 1930 79c3c C6 Yeah, it's it's a little 01:56.970 --> 01:58.740 bit tricky for black here. 01:58.770 --> 02:06.270 If black had castled in this position Rook D one this tempo again and Bishop E free looking A7 this 02:06.270 --> 02:12.090 great surface area of attack when when one cancels queenside, the surface area of attack increases, 02:12.090 --> 02:13.680 the responsibility increases. 02:13.680 --> 02:18.060 And yeah, there's not too many defend defending pieces around the king here. 02:18.360 --> 02:20.880 So anyway, C6 was played here. 02:21.030 --> 02:32.070 Bishop e free Queen e5 Rook 81 e6 and now alekhine underpins the Bishop basically Queen F3 and this 02:32.070 --> 02:34.710 actually is a really interesting position. 02:36.060 --> 02:39.090 Blank is dissuaded from a normal looking move. 02:39.120 --> 02:47.160 Bishop e7 here this wasn't played black castled queenside at move 14 if Bishop e seven There's an interesting 02:47.190 --> 02:48.330 tactic here. 02:48.960 --> 02:50.580 Can you see what that is? 02:50.910 --> 02:52.740 If I give you 5 seconds to pause video. 02:56.040 --> 02:57.600 Well, black is not even French things. 02:57.600 --> 02:59.730 Castle was a tasty seven, though. 02:59.970 --> 03:03.720 So white can actually exploit the king in the center here with 95. 03:03.720 --> 03:05.730 So well done if you sponsored this. 03:05.730 --> 03:06.060 See? 03:06.060 --> 03:07.950 Takes this route takes 87. 03:08.190 --> 03:10.110 Just celebrating the king in the center. 03:10.110 --> 03:14.940 So this situation would be very dangerous if we have Bishop de six. 03:15.630 --> 03:20.010 Can you see what one could play him, which is going to be a winning combination? 03:20.010 --> 03:22.380 If I give you 5 seconds, pause with the other hand. 03:22.380 --> 03:23.220 What were you playing? 03:26.860 --> 03:27.050 Yeah. 03:27.160 --> 03:28.240 Route 66. 03:28.240 --> 03:30.150 Jack Bishop, Full check. 03:30.160 --> 03:31.510 The king is a bad defender. 03:31.540 --> 03:32.590 We can lure the king. 03:32.590 --> 03:33.130 Wayne Bishop. 03:33.130 --> 03:34.110 Tax efficient. 03:34.150 --> 03:35.470 And when the queen. 03:35.710 --> 03:37.480 So fascinating stuff. 03:39.010 --> 03:47.590 So black out move 14 the sign into castle queenside and this drops the A7 pawn. 03:48.860 --> 03:52.480 So yes, Black is not doing so well here. 03:52.490 --> 03:53.500 Queen 85. 03:53.510 --> 03:58.730 The bishop goes back to D4 trying to tie up this bishop on F eight. 03:58.760 --> 04:02.340 We have Queen A5 White refuses the Queen exchange. 04:02.810 --> 04:04.550 E5 The bishop drops back. 04:05.030 --> 04:09.140 Bishop b4 and then we have A4 looking at that B six square. 04:09.590 --> 04:13.730 Bishop a5 And now A4 is interesting. 04:13.820 --> 04:17.690 So this looks as though it's a little bit anti positional blocking in the bishop. 04:19.140 --> 04:22.830 Bishop ice bishop going back to 87 is interesting here. 04:22.890 --> 04:29.460 So this situation with Queen a free might have been in a way potentially more accurate way of playing 04:29.460 --> 04:30.450 this position. 04:30.570 --> 04:31.770 There's things like rook tanks. 04:31.770 --> 04:34.650 These seven and a 95 were a strong attack. 04:34.650 --> 04:38.520 The queen can look at and be seven in some occasions. 04:39.180 --> 04:45.540 If Bishop B ain't queen ain't, for example, here 9a4, it starts to be quite dangerous for black. 04:45.780 --> 04:47.240 So, yes, fascinating stuff. 04:47.250 --> 04:49.950 F4 looks a little bit anti positional. 04:50.250 --> 04:58.170 So, yeah, Bishop 87 might have actually been an interesting alternative there but F4 Och Bishop C 04:58.170 --> 05:04.300 seven Black misses a shot here to kind of lock down this diagonal to shut it down. 05:04.320 --> 05:08.490 This could be at some point, you know, a dangerous diagonal if E4. 05:08.520 --> 05:11.970 This position should be about even here. 05:12.480 --> 05:17.040 But Bishop's C seven was played be frank and six. 05:18.990 --> 05:19.620 Clearly. 05:19.620 --> 05:21.780 If it's not clearly, I'll show you. 05:21.780 --> 05:27.020 If Black place E takes, then one has a lot of dynamic play on the F file now as well as the diagonal. 05:27.030 --> 05:32.190 This is not very good idea to have all this pressure against the king. 05:32.490 --> 05:34.590 So that would be very, very dangerous for black. 05:34.590 --> 05:45.990 So f thinks f times, Queen E thinks if queen tanks, e five hair bishop perform the Queen 951 can take 05:45.990 --> 05:47.880 on C seven and then take on G seven. 05:47.880 --> 05:52.320 Actually, don't be plausible here with advantage. 05:52.320 --> 05:55.200 So Queenie six H Frink. 05:57.090 --> 05:58.530 Look, H.G. ain't. 05:59.820 --> 06:01.560 We have Bishop Defoe. 06:01.650 --> 06:03.220 Any time you might ask. 06:03.240 --> 06:04.560 Any time Bishop takes any form of this. 06:04.560 --> 06:06.990 Bishop, I, for one, should have something here. 06:07.260 --> 06:17.610 So I was playing bishop for 1965, and then the queen switches to see 397 and now the start of a form 06:17.610 --> 06:23.940 -- installation sci fi with the idea of 96 at some point to try and get a very dangerous pawn potentially 06:23.940 --> 06:24.930 around the king. 06:25.440 --> 06:29.240 So this is a very dangerous attacking strategy in its own right, in my view. 06:29.250 --> 06:33.420 And neural networks have emphasized form -- based attacks. 06:34.170 --> 06:36.780 And even in games, they can be dangerous. 06:36.780 --> 06:42.780 Still, of course, they can sometimes be weak, but here there's a potential for 96. 06:42.780 --> 06:48.930 Now, it's not used immediately before might be eight, and now it's used 96 check. 06:49.200 --> 06:52.200 So we get this kind of form pawn around the king. 06:52.200 --> 06:57.390 It's like a gold hanging pawn, You know, like in European football, it wouldn't be allowed to be 06:57.390 --> 06:58.290 a gold hanger. 06:58.500 --> 07:01.620 It's just supporting potentially dangerous tactics. 07:01.620 --> 07:03.570 We have Queen takes a two. 07:03.870 --> 07:09.030 And now with the absence of black starts, Squire Bishop White is welcome on this diagonal. 07:09.870 --> 07:12.630 Queen Gfriend friend a mate front now Queen C seven. 07:12.630 --> 07:20.640 Thanks to the pawn, we have Rook D7 and our Bishop c5 so the rook can't leave C7 because of Queen C7. 07:21.270 --> 07:23.400 So this is interesting. 07:23.400 --> 07:30.660 Bishop takes F6 was also kind of interesting here to try and get rid of the defender. 07:30.660 --> 07:35.910 So if Queen of some Rook takes D7 and this position is good for white. 07:36.510 --> 07:39.330 So yeah, there was actually an opportunity for this. 07:39.330 --> 07:43.320 This gets very dangerous if once Rook takes D7 and Queen C7. 07:44.310 --> 07:53.490 So anyway, Bishop C5 though was playing Queen f7 Rook one, Queen G six and now tucking in on A2 just 07:53.490 --> 07:59.970 to keep on that dangerous diagonal, keep the potentially outrageous forcing moves alive like this, 07:59.970 --> 08:05.640 this queen takes in some orations that might be useful to have that threat that that action we have. 08:05.640 --> 08:08.940 Queen So that would that that's kind of interesting. 08:08.940 --> 08:17.760 Queen H two Queen fool was plausible of Queen E for Queen F to this position with Rook. 08:18.270 --> 08:19.770 It is better for Wayne. 08:21.900 --> 08:27.300 Okay so anyway, so rookie won here Rookie five. 08:29.480 --> 08:41.180 If Queen E for Rook eight, Queen E five to protect b81 could take and this position is favorable. 08:41.210 --> 08:45.050 Pick Bishop Geoffrey Rook defray to stop Bishop G. 08:45.500 --> 08:49.010 King HD to renew Bishop Geoffrey this position. 08:49.190 --> 08:56.330 Bishop Geoffrey happens with advantage So yes, Queen falls not great but rookie five played rook eight 08:56.630 --> 09:06.800 rook D two And this is the start of a combination so rook d2 doesn't really help Queen D Queen D friend 09:06.800 --> 09:10.880 being played Queen A4 is interesting. 09:11.000 --> 09:21.890 So this position, for example, is going to be kind of pleasant for white overall trying to break down 09:21.890 --> 09:23.620 this diagonal with rookie form. 09:23.630 --> 09:24.530 Maybe later. 09:24.740 --> 09:27.530 This is fictional, but this kind of thing. 09:29.170 --> 09:29.860 Is interesting. 09:29.860 --> 09:31.630 You know, it's in its favor. 09:32.920 --> 09:35.290 But Ruthie, too, was planed. 09:36.580 --> 09:42.940 And this leads to a spectacular combination involving the power of this form pawn taking out escape 09:42.940 --> 09:43.690 squares. 09:44.230 --> 09:46.080 So there's a great combination here. 09:46.090 --> 09:46.890 Can you spot it? 09:46.900 --> 09:49.690 You might want to pause the video here for 500 points. 09:49.690 --> 09:51.130 It's really amazing. 09:51.550 --> 09:55.060 It's a very, very cute finish here. 09:57.550 --> 09:58.930 I'm about to reveal. 09:59.920 --> 10:01.840 It's ideal if you can work it out to the ends. 10:01.870 --> 10:04.900 These tactics based on forcing moves. 10:04.990 --> 10:05.860 Checkerboard Change. 10:05.860 --> 10:12.640 Checkerboard captures checkerboard major frets like making one ideally. 10:12.670 --> 10:15.730 So rook tanks, bait check, king tanks. 10:15.730 --> 10:20.740 And now we can see that that form pawn is covering two key escape squares. 10:20.740 --> 10:25.090 And the potential for a back row mate has basically just increased. 10:25.210 --> 10:30.160 So how can we basically amplify back row mate mating pattern here? 10:31.080 --> 10:33.510 I hope you've spotted Queen size five. 10:33.520 --> 10:35.070 Jack Black has to resign. 10:35.340 --> 10:36.180 If King C. 10:36.180 --> 10:38.040 S Queen C seven is checkmate. 10:40.690 --> 10:45.580 Otherwise, if F takes Rook can feint and we're basically going into a bank run make pattern. 10:46.450 --> 10:47.620 Wonderful stuff. 10:47.620 --> 10:54.280 How this kind of attack is built up in this game, this arrangement of trying to get a very dangerous 10:54.280 --> 11:01.330 like form pawn around the king, I believe is, you know, a key attacking strategy quite often. 11:01.690 --> 11:05.520 So the gambit was also an interesting aspect. 11:05.530 --> 11:14.290 Building up the pressure from this gambit is just it puts black on a back foot here where there's a 11:14.290 --> 11:21.190 temptation to castle queenside because of this default pressure, nagging pressure on the defile which 11:21.190 --> 11:26.050 kind of dissuades natural moves like Bishop E7, because any time castling we're just going to take 11:26.050 --> 11:26.980 on D7. 11:26.980 --> 11:33.280 So Black Castle in Queenside was basically the first major concession from this gambit. 11:33.280 --> 11:35.500 So equal on pawns now. 11:35.500 --> 11:43.630 But B6 being punched creates a routine for a piece on B6 to try and get a very, very dangerous goal 11:43.630 --> 11:44.800 hanging pawn. 11:45.070 --> 11:50.200 So it's very, very interesting and for might not have been entirely optimal. 11:50.200 --> 11:56.590 There are lines, the engines, Bishop, A7 and Queen A3, but Black didn't shut down this diagonal 11:56.740 --> 12:04.240 and so got into trouble later on that diagonal, even though at the moment it looks secure when things 12:04.240 --> 12:05.320 like the form pawn happens. 12:05.320 --> 12:13.030 It also took away the defensive dance when Bishop so reactivating interest in that diagonal soon so 12:13.030 --> 12:19.300 that guardian bishop guardian guarding the diagonal taken out of the equation as part of installing 12:19.450 --> 12:21.190 this dangerous form pawn. 12:21.190 --> 12:23.410 So that's two birds with one stone. 12:23.410 --> 12:30.520 So this diagonal much more sensitive again and white getting quite quickly on on the frets And so rook 12:30.520 --> 12:36.100 takes D one there's Queen C seven checkmate And there's also ideas of Rook one Rook eight So yes, black 12:36.100 --> 12:38.180 was definitely in a bad way here. 12:38.230 --> 12:42.670 The queen, you know, relentlessly on this diagonal of Queen H two. 12:42.670 --> 12:46.480 So leading to this wonderful combination here, great stuff. 12:46.480 --> 12:48.160 You know, this is absolutely beautiful stuff. 12:48.160 --> 12:50.620 So game ending on Queen takes E5 check. 12:50.620 --> 12:56.110 I hope you enjoyed this game and patterns of the form pawn creation, but with it it did actually get 12:56.110 --> 12:57.640 that important dance Great bishop. 12:57.640 --> 13:04.060 So keeping this diagonal even more sensitive after Black's guardian bishop was out of the picture. 13:04.360 --> 13:06.420 Okay, I'd say much.
