WEBVTT 00:01.220 --> 00:02.120 Hi there. 00:02.150 --> 00:06.500 In this lecture, we see an interesting British championship game between Michael Adams and Grandmaster 00:06.500 --> 00:07.090 Aaron Sommers. 00:07.100 --> 00:11.900 Kelso, both Grandmasters 2010 British Championship, Round 2e4. 00:11.900 --> 00:12.410 From Adams. 00:12.410 --> 00:17.120 We see a kraken from some skull d4d5. 00:17.120 --> 00:18.200 We have E five. 00:18.200 --> 00:21.980 The advanced variation Bishop F five, nine three, E six. 00:21.980 --> 00:23.900 And now the Nigel Short innovation. 00:23.900 --> 00:26.030 This is so much better than Bishop de Fray. 00:26.060 --> 00:30.780 This gives a slight advantage in the position if Bishop de Fray. 00:30.800 --> 00:32.600 This is too easy for black blacks. 00:32.600 --> 00:34.310 Just got rid of their bad bishop. 00:34.430 --> 00:40.220 It's like an improved French defense and there's classic games like Nimzowitsch against Capablanca showing 00:40.220 --> 00:45.620 this theme that black can actually use the light squares later, for example, more easily. 00:45.620 --> 00:49.970 So Bishop E2 keeps the variation alive, thanks to Nigel Short. 00:50.000 --> 00:50.930 The short variation. 00:50.930 --> 00:54.470 So c5a short bishop move rather than to D three. 00:54.470 --> 00:58.410 So C five Bishop f3 C takes D four. 00:58.430 --> 01:03.500 There are some very interesting lines with Queen B six here because you might think there's punishment 01:03.500 --> 01:05.870 of a weakness of the last move for B two. 01:06.920 --> 01:09.920 However, there is a bit of a stunning idea here. 01:10.190 --> 01:15.700 9c3 and yes, we might as well look at these openings while we're here. 01:15.710 --> 01:22.280 So nine C free if Queen takes B to guess what white can do here, which is absolutely amazing. 01:25.280 --> 01:26.210 At some points. 01:28.050 --> 01:29.040 And Queen Bee one. 01:29.040 --> 01:31.470 Maybe this is in Adams preparation anyway. 01:31.590 --> 01:36.630 If Queen takes C three, check Bishop DD two, Queen three. 01:36.630 --> 01:38.160 We have Queen takes B seven. 01:38.160 --> 01:42.750 And this is very, very dangerous now for Bishop B five and other stuff. 01:42.750 --> 01:48.870 So for example, F six, Bishop B five check, and then Queen takes eight when it's clearly winning. 01:48.960 --> 01:51.630 So this is very, very dangerous, this noisy free. 01:52.590 --> 01:55.560 It's so much better than say, C for this. 01:55.560 --> 01:56.700 This is not the idea. 01:56.700 --> 01:59.220 I believe this is just going to be equal. 01:59.220 --> 02:03.660 But if we play nine C free, this is really, really interesting. 02:03.750 --> 02:11.820 After Queen takes B2, Queen B one and if Queen takes B one check you might ask, This is a strong position 02:11.820 --> 02:12.930 for off the details. 02:12.930 --> 02:19.260 We can try and activate our pieces more like B five threatening 97 check. 02:19.560 --> 02:21.900 And there's all sorts of nasties here. 02:22.050 --> 02:28.290 For example, King d89 takes a seven because we're looking at B eight and here we're getting a significant 02:28.290 --> 02:29.970 advantage in this position. 02:29.970 --> 02:33.030 So yes, the variation has some teeth of the Queen. 02:33.030 --> 02:34.920 B six in terms of nine C free. 02:35.730 --> 02:37.020 Yeah, there's some teeth here. 02:37.170 --> 02:40.770 So anyway, C takes the four was played, Knight takes the four. 02:40.770 --> 02:43.650 We have 9792. 02:44.130 --> 02:48.750 When I say handsome thief, I mean as the potential for a really significant advantage. 02:49.050 --> 02:51.960 It's kind of digging in metaphorically into black's position. 02:51.960 --> 02:59.910 So anyway bc6 we have 92 to f three Bishop E for White Castles, 9g6. 02:59.910 --> 03:04.260 So it seems as though White's learnt the pawn chain and says let the pawn chain be undermined. 03:04.350 --> 03:05.700 But Bishop be fine. 03:05.700 --> 03:09.540 There's a very interesting positional pawn sacrifice here. 03:09.540 --> 03:14.310 9g5 So black is on the fire. 03:14.310 --> 03:21.090 Here we have Knight G takes E five, Bishop e seven, F three and this square bishop is in trouble of 03:21.090 --> 03:22.080 the G four. 03:22.470 --> 03:23.460 It's trapping the bishop. 03:23.460 --> 03:25.050 This would be to White's advantage. 03:25.050 --> 03:31.170 So we see Black accepting this kind of position or pawn sacrifice, which I thought was remarkable at 03:31.170 --> 03:31.890 the time. 03:32.130 --> 03:39.900 F four Now with tempo 96 nine takes e four when it's forcing matters F five, another forcing move E 03:39.900 --> 03:46.140 takes if 9ge5, F takes e six after its knight. 03:46.140 --> 03:48.630 Take C six, nine take six. 03:48.630 --> 03:53.070 Queen takes these seven check King takes these seven Rook have seven check here. 03:53.070 --> 03:59.070 This is going to be a big position after Bishop take c6b takes rook d one big position for white. 03:59.460 --> 04:01.740 So anyway, he takes is played. 04:01.740 --> 04:06.960 We have bishop take c6b takes Knight takes a five. 04:08.730 --> 04:14.340 Queen Tanks RD one So Black is still right now a pawn up. 04:14.340 --> 04:19.050 But White's pieces are better and it's going to be getting back material. 04:19.050 --> 04:29.100 We have 95 if Rook D eight, then White can take on D eight King Thanks and take on a7321 pawn majority 04:29.100 --> 04:36.390 over here and here 93 The E four pawn is extremely vulnerable whilst these guys are just asleep still 04:36.390 --> 04:38.670 and also f seven can be taken. 04:38.670 --> 04:40.620 So that's unpalatable. 04:41.130 --> 04:42.690 So we have 95. 04:44.860 --> 04:47.680 So Avon is protected here still. 04:49.000 --> 04:51.070 We have, though, a weakness for the last move. 04:51.070 --> 05:00.320 It's neglected for won't users care for to pick up -- so equal or material g sex if King of seven 05:00.340 --> 05:01.570 let's have a look at this position. 05:01.570 --> 05:04.720 Be free h5y It should be a little bit better. 05:04.720 --> 05:06.190 But it's not the end of the world just yet. 05:06.190 --> 05:08.310 For blank, there's still work to do. 05:08.320 --> 05:11.020 So G six were played like D six. 05:11.020 --> 05:15.430 Jack Bishop takes these six Rook takes these six black castles. 05:16.330 --> 05:17.440 Bishop H six. 05:17.440 --> 05:24.070 Now the rook can't leave the f pawn so the place to f seven we have h three. 05:24.070 --> 05:26.320 But now a drastic mistake, rookie. 05:26.320 --> 05:28.930 Ain't this makes things easier for white? 05:30.490 --> 05:37.090 Yeah, this makes things easier because there's a pin point here and white it has Rook take C six. 05:37.090 --> 05:37.600 Yeah. 05:37.600 --> 05:42.370 Why was this move played entertained other is black's position not bad. 05:42.520 --> 05:44.500 Funny enough after rook. 05:44.510 --> 05:44.950 Okay. 05:44.950 --> 05:51.430 It's difficult to exactly determine if this is such a big advantage for white. 05:51.460 --> 05:58.270 Probably a clear cut attempt at simplification is Bishop F4, which is not even one of the top engine 05:58.270 --> 05:58.510 moves. 05:58.510 --> 06:00.790 But it is a way of simplifying the position. 06:01.330 --> 06:08.140 And as example here we can actually try and increase advantage with more active rooks with white. 06:08.140 --> 06:10.380 You know, this is just a fictional smart scenario. 06:10.390 --> 06:16.750 If we get a breach onto the seventh Frank here with this other pawn sac so it'll be equal on pawns, 06:16.750 --> 06:22.210 this position might actually be the way to go where White's got more active rooks and a better rook 06:22.210 --> 06:23.170 and pawn ending. 06:23.170 --> 06:24.850 But, you know, there's work to do. 06:24.850 --> 06:26.500 There is actually work to do here. 06:26.710 --> 06:28.240 It's not that clear cut. 06:28.450 --> 06:34.930 You know, this is just a totally fictional scenario where White can get an advantage from a rook and 06:34.930 --> 06:38.350 pawn ending here to 2 to 0 on the kingside. 06:38.590 --> 06:40.090 This would be to White's advantage. 06:40.090 --> 06:46.840 But if we do other stuff here, like, for example, be free, it's less clear cut. 06:46.900 --> 06:52.630 How white actually breaks through for anything, especially if this bishop's kind of locked in for a 06:52.630 --> 06:53.200 moment. 06:53.230 --> 06:54.880 What is White actually doing here? 06:54.880 --> 06:59.710 Even though technically it seems better for white, there doesn't seem to be a clear cut resolution 06:59.710 --> 07:02.950 here, difficult to make progress in terms of increasing their voice. 07:02.950 --> 07:11.920 So I would say Bishop F4 is the point that was causing concern for Masco, because that is a kind of 07:11.920 --> 07:17.770 positional move in a sense of trying to exchange off one of the opponent's better pieces for one of 07:17.770 --> 07:18.730 your pieces. 07:19.060 --> 07:24.370 So anyway, for whatever reason, yeah, this, this looks like a mistake. 07:24.550 --> 07:25.990 It's losing a key pawn. 07:25.990 --> 07:30.100 Rook, take C six so we have G five. 07:30.640 --> 07:32.860 Unless the idea was to try and champion the bishop. 07:32.860 --> 07:37.600 But it's not really that trapped We have be free rook for seven. 07:38.870 --> 07:39.620 Yeah. 07:39.620 --> 07:45.550 And this kind of does seem to make things more simple in a way. 07:45.560 --> 07:47.090 After tax takes six. 07:49.760 --> 07:51.590 Actually, let's give a concrete example. 07:51.590 --> 07:54.890 So instead of for seven, say, A for how does one actually make progress? 07:54.890 --> 08:02.120 Well, see, for here we get we're not worried about 9/10 because the rook takes it ain't so king hates 08:02.120 --> 08:08.510 C five now the rook moves okay we'll move the rook to D six and we're making way with the pawn. 08:08.630 --> 08:09.980 We're making progress with the pawn. 08:10.010 --> 08:10.220 See? 08:10.220 --> 08:15.920 695 and say, Rook four So a five can become a target here. 08:17.120 --> 08:22.280 And yes, it's it's just difficult for black to do anything really. 08:22.280 --> 08:25.180 So say Rook c seven Black is going to lose material. 08:25.220 --> 08:27.110 But what is black actually doing here? 08:27.770 --> 08:30.470 Rook takes a five is coming and then further progress. 08:30.470 --> 08:36.350 So yes, it does seem as though this shedding with second pawn is pretty sad. 08:36.350 --> 08:37.340 State of affairs. 08:37.340 --> 08:40.520 There's no free check here because of G states protecting the rook. 08:40.520 --> 08:43.130 There's no trick there on the rook either. 08:43.400 --> 08:47.300 So yes, this this is a very, very bad position now. 08:47.300 --> 08:52.370 So 97 here, rook takes e seven, seven, rook six. 08:52.370 --> 09:00.740 And here some scowl resigned if g4h takes this position Rook have six because threatening rook f eight 09:00.740 --> 09:01.480 Checkmate. 09:01.490 --> 09:06.680 So there's no time for nine takes g four and here rook have 596 rook C five. 09:06.680 --> 09:09.620 White's advantage is just huge here by this point. 09:09.620 --> 09:15.860 So an interesting game, a very interesting opening variation and it has some particular traps which 09:15.860 --> 09:16.610 are fascinating. 09:16.610 --> 09:21.230 So yeah, this is the advance version of the korakuen used by atoms. 09:21.230 --> 09:23.390 So very, very interesting with this. 09:23.420 --> 09:24.740 Nigel Short Innovation. 09:24.740 --> 09:28.430 Bishop Ito, I hope you enjoyed this one and so much.
