WEBVTT 00:01.290 --> 00:02.010 Hi there. 00:02.490 --> 00:07.860 In this lecture, we see an amazing game between Genki buying and thing learn. 00:08.460 --> 00:10.320 So this is in 2017. 00:10.980 --> 00:15.270 The Chinese Chess League D4 from buying. 00:15.300 --> 00:17.490 We have things there on playing night of sex. 00:17.700 --> 00:19.880 C4 e6 we have 93. 00:19.890 --> 00:29.790 The names are Indian Defence Bishop e4 Knight have three Black Castles Bishop G5 and it does seem logical 00:29.790 --> 00:31.590 to play C5 here. 00:33.090 --> 00:36.990 There are possibilities of Queen A5 sometimes and C64. 00:36.990 --> 00:43.320 There are possibilities of breaking this pin sometimes for 94 to add pressure to C free. 00:43.740 --> 00:44.940 So it's an interesting move. 00:44.970 --> 00:51.450 C5 we have E free C tank, C4 Queen tanks, the nine C6 and the queen goes to DD free. 00:51.480 --> 00:55.840 Here we have H6, Bishop H4 and now D5. 00:55.860 --> 00:58.200 So this does seem very logical play. 00:59.310 --> 01:03.960 And potentially if a rook comes to the defile, if the queen moves and the rook comes to the default, 01:03.960 --> 01:06.090 there's a target ready and waiting. 01:06.420 --> 01:09.750 So we see Rook dd one the queen of the target on D3. 01:09.750 --> 01:20.250 So Rook D1 if C takes D5 here, E takes D5 this position Black can play aggressively with G5 for 94. 01:20.610 --> 01:24.420 Ordinarily, this would be a lot of weaknesses being represented by here. 01:24.420 --> 01:29.460 It's kind of justifiable because Bishop takes C3 wrecks a little bit. 01:30.330 --> 01:34.830 The structure of White's and Bishop F5 is a nice position in general. 01:35.910 --> 01:38.880 Well, in specifically, it's a nice position here. 01:40.260 --> 01:46.470 Even though Black's got the isolated Queen's pawn, Black has sufficient play and there is a structural 01:46.470 --> 01:48.060 issue on C3 right now. 01:48.900 --> 01:51.090 So Rook D one is played. 01:51.840 --> 01:57.420 We have G5 Bishop G3 94 here and now 92. 01:57.450 --> 02:04.500 You'll note that this kind of weakens D4 control and thing therein uses that fact. 02:04.530 --> 02:13.170 Knight C5 Queen C two He actually uses D4 here despite the rook and strong Black's queen on this occasion. 02:13.170 --> 02:21.050 Here we have 90 have free one else if Bishop E2 and D3 ouch winning material. 02:21.060 --> 02:24.420 So Knight's afraid looks as though well, you know, this is pen. 02:24.450 --> 02:25.560 What is black doing here? 02:26.100 --> 02:28.320 Well very dynamic move in this position. 02:28.320 --> 02:31.170 So what would you play here for Ten points? 02:31.500 --> 02:35.250 Black's play is a very logical looking move. 02:39.600 --> 02:46.350 A logical looking pawn sacrifice has great perks here to open up against the king in the center. 02:46.800 --> 02:49.740 Intuitively, this pawn is taken. 02:50.370 --> 02:53.420 If Bishop e to her, then Queen F sinks. 02:53.430 --> 03:00.850 And here we can play Bishop F five, and Bishop takes C free check. 03:00.870 --> 03:03.930 If Bishop a5 there is b4 as possibility. 03:03.930 --> 03:04.820 So let's go with Bishop. 03:04.830 --> 03:09.030 Take C free check and just D free is very impressive. 03:09.060 --> 03:10.470 Black has a big advantage there. 03:11.750 --> 03:13.490 Putting the bishop back in his box. 03:13.940 --> 03:14.960 It's just terrible. 03:15.530 --> 03:16.580 Okay, so. 03:18.310 --> 03:22.060 Thanks E5 is played, so here is a crunch moment. 03:22.600 --> 03:24.970 So what would you play in this position? 03:26.690 --> 03:27.770 400 points. 03:30.530 --> 03:31.610 So a crunch moment. 03:31.690 --> 03:33.860 A pawn has been sacrificed. 03:35.180 --> 03:36.950 We have a spectacular. 03:38.280 --> 03:38.790 Details. 03:38.820 --> 03:42.150 Sea freight offering the Queen Queen sacrifice. 03:42.150 --> 03:46.410 So this is often the prelude to a king hunts to bring the king down the board. 03:46.590 --> 03:49.890 Do we really have such a hunt before we get into that? 03:49.890 --> 03:53.140 If Queen f6 E-Type C4. 03:53.160 --> 03:59.190 This is all so slightly fascinating because the Bishop are five and Rook 88, putting a lot of pressure 03:59.190 --> 04:07.620 on D4 if 19 C six because D takes we're just going to take on D1 and then take on E5 with the advantage. 04:08.580 --> 04:14.730 Essentially this this is just nice that E4 is is nice. 04:17.200 --> 04:18.070 So here. 04:19.710 --> 04:26.190 Let's imagine 1936 this position is actually playable for black if free. 04:26.220 --> 04:31.740 This is very awkward position because otherwise if defined that it is very dangerous. 04:32.160 --> 04:37.470 Rookie eight Check an A free check Bishop takes the free. 04:37.470 --> 04:42.930 This position is crazy, but Black is winning the Knights not influencing E2. 04:43.740 --> 04:52.920 And if King if one rookie to check Bishop take see free check taking hair and black is a whole rook 04:52.920 --> 04:53.280 up. 04:53.280 --> 04:58.710 So there are interesting examples where basically if white doesn't play a free hair, one's getting 04:58.710 --> 04:59.870 blown off the board. 04:59.880 --> 05:02.310 So let's continue on F3 a check. 05:02.640 --> 05:05.850 And this position is is fascinating. 05:05.850 --> 05:07.550 King G one rook takes the form. 05:07.560 --> 05:15.420 There is Bishop F2 and one can just about hold on here so this position is holding on for white with 05:15.420 --> 05:17.760 equality in a technical sense. 05:17.880 --> 05:24.780 So that's crazy stuff and that's if Queen f6 is played it isn't totally lost black with Queen f6, but 05:24.780 --> 05:28.140 this queen sacrifice is very, very interesting. 05:28.140 --> 05:34.470 We have Rook takes the C tanks B to check and F King E2 is played with the idea of marching the king 05:34.470 --> 05:34.980 out of the board. 05:34.980 --> 05:36.120 It's quite ambitious. 05:36.150 --> 05:42.780 Rook D2, it seems, might actually be playable, but it requires white to play with very high precision 05:42.780 --> 05:45.690 here with Bishop D frame. 05:48.920 --> 05:49.670 And. 05:51.010 --> 05:56.110 The thing is here, we want to play something like B1 one. 05:56.110 --> 05:57.240 We want a queen. 05:57.250 --> 05:59.050 If it takes five. 05:59.700 --> 06:04.300 One can avoid disaster continuations here. 06:05.110 --> 06:06.100 Funny enough. 06:06.220 --> 06:08.140 One move and one move only. 06:09.310 --> 06:10.370 Can you see what that is? 06:10.390 --> 06:13.120 Why it needs to keep an eye on the B1 one square. 06:13.870 --> 06:14.290 And so. 06:14.290 --> 06:18.180 Bishop H seven check and Bishop takes E5. 06:18.190 --> 06:24.160 So even if the Queen has to give herself up, the bishop is covering the one here. 06:24.190 --> 06:24.850 Crucially. 06:24.850 --> 06:29.260 So this position ends up being actually equal. 06:29.530 --> 06:35.440 So maybe that is very, very difficult to calculate, but it is possible. 06:35.440 --> 06:39.280 It seems in a technical sense that Rook D2 would have been okay for whites. 06:39.790 --> 06:40.720 It's scary stuff. 06:40.750 --> 06:42.130 That's just recap that. 06:42.430 --> 06:44.500 So yeah, these situations. 06:45.490 --> 06:51.250 If Bishop takes E5, then Rook takes the fray is is crushing. 06:51.250 --> 06:56.950 This position is going to be crushing because there's nightly free check here for example and black 06:56.950 --> 06:57.820 ends up material up. 06:57.820 --> 07:04.960 So there's only one way of playing it with Bishop 87 check and here if you know B1 as example you know 07:04.960 --> 07:07.810 we're just taking that and just playing King E2 here. 07:07.840 --> 07:08.620 No problem. 07:08.740 --> 07:09.870 It's got a big advantage there. 07:09.880 --> 07:15.770 But yeah, there's one route here which we've best played from both sides. 07:15.770 --> 07:17.710 It ends up with uneven position. 07:17.860 --> 07:21.880 But anyway, in the game King E2 is played. 07:22.210 --> 07:25.360 We have Rook takes the eight and now Queen takes B2. 07:25.360 --> 07:29.410 So that Dangerous Pawn eliminated 94. 07:29.410 --> 07:32.320 Queen C two Knight C Free Shaq King Afraid so. 07:32.320 --> 07:33.940 What is Black's point here? 07:36.040 --> 07:40.630 Well, if King's being brought up the board, we want to sometimes control escape squares. 07:40.660 --> 07:43.750 G4 check is not quite checkmate in King F4. 07:45.620 --> 07:47.060 So we play G4. 07:47.090 --> 07:48.620 Also there's 96 G for. 07:48.650 --> 07:51.350 There's a few snags to tax G for as well. 07:52.160 --> 07:53.960 So just bear that in mind. 07:53.960 --> 08:00.440 This next move does actually make G more important and it controls the escape squares. 08:01.850 --> 08:02.450 So yeah. 08:02.480 --> 08:04.820 King Free is interesting actually. 08:04.820 --> 08:08.090 Before we even go there, if King E one had been played. 08:11.330 --> 08:13.010 What will be the solution here? 08:13.190 --> 08:15.680 So let me just test you on King E1 for a moment. 08:18.110 --> 08:21.500 Blake has a solution to this position with Bishop F5. 08:22.100 --> 08:27.020 So this is very dangerous because if the Queen leaves the one, then there's Rook D1. 08:27.020 --> 08:27.800 Checkmate. 08:29.270 --> 08:33.440 And if Bishop D Free Rook takes the E3 1963 Rook d8. 08:33.440 --> 08:37.760 This is a horrible pen situation where black ends up. 08:38.600 --> 08:39.440 Much better. 08:39.470 --> 08:42.950 So if he takes Rook D1 is checkmate there? 08:47.000 --> 08:50.510 And if 95 year plan ends up being material up. 08:50.750 --> 08:53.510 So okay, so I hope you convince King free. 08:53.510 --> 08:55.330 So back to King and free. 08:55.340 --> 09:00.320 This position has a magnificent move to make G4 strong. 09:00.320 --> 09:07.580 So what is this move for 200 points I really truly magnificent move. 09:08.450 --> 09:16.580 It's rook d4 it has this front now of G4 mating essentially G4 will be mating after nine. 09:16.580 --> 09:18.500 Thanks, Bishop. 09:18.500 --> 09:18.740 Thanks. 09:18.740 --> 09:20.180 G4 will be champ, mate. 09:20.420 --> 09:22.340 Let me put that on the board. 09:24.990 --> 09:26.610 So had G for check. 09:26.610 --> 09:28.480 And you can see that all the escape squares are taken out. 09:28.500 --> 09:29.160 That's the main. 09:29.460 --> 09:36.120 So okay white place H frame if queen site C frame. 09:36.150 --> 09:37.800 That's desperate looking Bishop Tanks. 09:37.800 --> 09:38.640 E tanks. 09:38.880 --> 09:39.900 1964. 09:39.900 --> 09:45.620 Check This position is going to be better for black. 09:45.630 --> 09:51.900 The king stuck in the center is the issue here, even though it seems as though material is even. 09:51.900 --> 09:54.660 But if we look at this, the checks are quite vicious. 09:54.900 --> 09:57.360 The pressure is quite vicious against the king and white. 09:57.400 --> 09:59.220 It's going to end up losing material. 10:00.890 --> 10:01.190 Yeah. 10:01.190 --> 10:11.960 If instead of Bishop cc7c1 is vicious Bishop the Fool Jack Bishop E free with a big roti to make France 10:11.960 --> 10:14.710 so hare Bishop sexy whites losing material. 10:15.760 --> 10:16.250 Yeah. 10:17.990 --> 10:24.140 And if we look at this again with Bishop Ray, if might be afraid, then Bishop E6, then the king is 10:24.140 --> 10:27.260 absolutely helpless in the center in this situation. 10:27.500 --> 10:31.010 And, you know, for example, like this is checkmate. 10:31.520 --> 10:34.130 So, okay, so h free is choice. 10:34.160 --> 10:35.800 No count of queen sacrifice here. 10:35.810 --> 10:36.770 It's no point. 10:38.480 --> 10:47.780 We have now h5 renewing the idea of G for mating combination Bishop h two and now G for check King Geoffrey. 10:48.110 --> 10:51.590 And now this is an only move situation here. 10:51.590 --> 10:54.200 Blacks only move for a big advantage. 10:54.230 --> 10:57.560 Can you see what it is for 100 points?
