WEBVTT 00:00.720 --> 00:01.450 Hi there. 00:01.470 --> 00:08.070 In this lecture, we see the very talented David Hell grandmaster against Michael Adams in 2011, British 00:08.070 --> 00:09.960 Championship round six. 00:09.960 --> 00:16.440 We see E four from David E, five, 93, 96, and now the Scotch game. 00:16.440 --> 00:23.280 So this has been revitalised by Garry Kasparov in recent events, relatively recent. 00:23.280 --> 00:29.010 We have e times d496349569 take c six immediately. 00:29.010 --> 00:35.670 This is actually kind of a dangerous line be takes to avoid the exchange of queens e five Now I know 00:35.670 --> 00:41.580 from bitter experience here that one has to really play Queen E seven in this position. 00:42.900 --> 00:50.100 It's not good to lose sense pawns if you look with engines and lose centre pawns of the engine like 00:50.100 --> 00:54.990 top moves, it can be a very painful experience with 95 hair. 00:54.990 --> 00:56.830 Bad idea y. 00:56.850 --> 01:02.880 It's getting a big positional advantage because this knight has got very low career prospects. 01:02.880 --> 01:04.470 For example, in this position. 01:04.800 --> 01:13.020 Once getting a dominating position here, for example, a five, a four to even just swap it off potentially 01:13.020 --> 01:14.160 with advantage. 01:14.160 --> 01:18.300 But it's pretty uncomfortable if instead. 01:18.940 --> 01:20.500 Of night before. 01:20.770 --> 01:26.350 If night be sex, then the night really sets badly on be sex in this position. 01:26.350 --> 01:30.790 And white has also a freedom that H seven has been abandoned. 01:30.790 --> 01:32.170 It's a softer spot than usual. 01:32.170 --> 01:37.250 So this is going to cause weaknesses if this -- has to move and won't just stand a lot better. 01:37.270 --> 01:43.660 This is an example of where we can't use positional play that easily to improve this piece and all structures 01:43.660 --> 01:44.330 damaged. 01:44.350 --> 01:46.030 It's really uncomfortable. 01:46.030 --> 01:46.680 We can try. 01:46.720 --> 01:48.220 Defined, but it could be ignored. 01:48.220 --> 01:56.710 So this is a safety point with this whole variation that actually Queen E seven creates things in Black's 01:56.710 --> 01:57.370 favor. 01:57.520 --> 02:04.240 So after Queen E to 95, the point is to be able to play Bishop a six sometimes. 02:04.240 --> 02:14.260 So if c four here, which wasn't played immediately, we can play Bishop a six and this justifies black's 02:14.260 --> 02:17.230 play more in the opening in the game is slightly different. 02:17.230 --> 02:20.230 Twist 92 first G six. 02:20.230 --> 02:25.480 This is a very useful move to hit E five That seems to be a potentially weak pawn C four now Bishop 02:25.600 --> 02:28.120 six and Black's position is pretty decent here. 02:28.630 --> 02:32.650 There is a really tactical adventure with 9f4, but it's probably not worth it. 02:32.650 --> 02:34.680 It's a bit wild this position. 02:34.690 --> 02:35.110 Sure. 02:35.110 --> 02:41.650 Black Windsor Pawn, but if Queen e free the point would be Bishop h649g2. 02:41.650 --> 02:46.810 But this isn't such a big deal to try and win the Queen because White can play King D one. 02:46.810 --> 02:52.270 And if we look at this position, even if we win the exchange here, we've compromised our dark squares 02:52.270 --> 02:53.500 around the king. 02:53.620 --> 02:57.370 And yeah, it's a funny position, but it's dynamically equal. 02:57.370 --> 03:01.180 Adams is playing more, avoiding those crazy complications. 03:01.180 --> 03:07.960 Bishop six We have three Queen B for check, though, and this prompts the king to move. 03:07.960 --> 03:12.850 So this is a really interesting position because otherwise B two is likely to be taken. 03:12.850 --> 03:16.420 It looks as though this is a really interesting position. 03:16.690 --> 03:21.430 Rook B eight Queen C2 So that's underpinning the pawn. 03:21.430 --> 03:23.380 So C takes is now threatened. 03:23.830 --> 03:25.090 The knight moves the E seven. 03:25.090 --> 03:26.110 It's not that bad. 03:26.110 --> 03:30.460 The Queen is vacated e seven for the knight to be not such a bad piece. 03:30.460 --> 03:32.320 Queen B three, C five. 03:32.770 --> 03:35.980 So undermining the pawns doesn't seem like a bad idea. 03:35.980 --> 03:37.150 And White obliges. 03:37.150 --> 03:40.780 Queen takes b4 C takes Bishop D free Bishop G seven. 03:40.780 --> 03:43.390 So this whole picture here isn't that bad. 03:43.390 --> 03:53.530 Four Black Black Castles Kings 290 6b4 it and now D five and energetic move exploiting the pinned pawn 03:53.530 --> 03:58.930 against a1c tanks is played and also another point now emerges. 03:58.930 --> 04:00.430 Bishop takes the free check. 04:00.430 --> 04:07.600 King takes Rook 58 we have Bishop and for giving the pawn back if King four There's a tactical point 04:07.600 --> 04:07.750 here. 04:07.750 --> 04:09.100 Can you see what that is for? 04:09.100 --> 04:09.940 Ten points? 04:13.000 --> 04:13.370 Yeah. 04:13.490 --> 04:14.500 Might takes 85. 04:14.530 --> 04:14.730 Yeah. 04:14.740 --> 04:16.390 There's an unprotected rock on E one. 04:16.390 --> 04:18.970 That's a potential downside we can tap into here. 04:18.970 --> 04:20.590 So nine takes Bishop Sykes. 04:20.590 --> 04:23.050 If King takes, we play, check and win the rook. 04:23.320 --> 04:26.050 So, Bishop, for giving the pawn back. 04:26.050 --> 04:28.180 But why still has an edge here? 04:28.180 --> 04:30.520 And David was playing like. 04:30.520 --> 04:36.400 Well, I'm Steinitz here with an aggressive king Rook five rook AC one and now 98. 04:36.400 --> 04:39.280 This is actually an inaccuracy from Michael Adams. 04:39.280 --> 04:43.480 97 seems to be helping to get equality. 04:43.480 --> 04:48.070 So 95 here Knight takes that four rook takes a two. 04:48.100 --> 04:49.900 This should be about even. 04:51.460 --> 05:02.920 But with 98 actually Rook 67 this possession with Roxy to rook d8h4h5g free. 05:02.920 --> 05:07.070 We have Bishop murphy and OC. 05:07.510 --> 05:12.250 Michael Adams has set up a nice Tigran Petrosian style blockade of the extra pawn. 05:12.250 --> 05:18.970 Y is actually a pawn up here, but it seems like an impenetrable fortress in some respects at least. 05:18.970 --> 05:25.900 And in fact White is very attracted to play position that you could say, try and get rid of this knight 05:25.900 --> 05:26.770 for this knight. 05:26.770 --> 05:31.870 But yeah, when we play a position like this to try and trade off certain pieces, we have to be aware 05:31.870 --> 05:38.470 of all the forcing moves which could cost a whole downside on lucrative plans. 05:38.470 --> 05:45.190 So this is a very interesting example where, yeah, we want to look at downsides of the opponent's 05:45.190 --> 05:45.760 position. 05:45.760 --> 05:46.510 Sure. 05:46.840 --> 05:47.950 Or play positioning. 05:47.950 --> 05:48.340 Sure. 05:48.370 --> 05:49.390 Get rid of a bad piece. 05:49.390 --> 05:52.480 But we have to look at the downsides of our implementation. 05:52.480 --> 05:54.370 There is actually a forcing move here. 05:54.370 --> 05:59.380 This is actually a huge mistake giving Black the advantage because of a nasty forcing move. 05:59.380 --> 06:06.830 Before we get into that, if Rook won, this gets more authority on the C file and this position OC 06:06.850 --> 06:07.930 King e free rook. 06:08.440 --> 06:10.330 It's not a big deal for white. 06:10.450 --> 06:13.840 In fact, White's amplifying the authority here soon. 06:13.990 --> 06:17.350 And even if one gives back a pawn, say that pawn is lost. 06:17.350 --> 06:18.430 It doesn't matter. 06:18.430 --> 06:21.670 This resigning position is in White's favor. 06:22.210 --> 06:28.000 Just to take this a bit further, let's say, you know Rook eight now threatens Bishop H six. 06:28.000 --> 06:30.010 Forget taking the pawn on 87. 06:30.010 --> 06:37.210 We've got Bishop H six and if Rook D five check and then attending to that King Jeffrey is strong. 06:37.210 --> 06:38.560 Forget Bishop takes a seven. 06:38.560 --> 06:43.540 For the moment this position is positionally strong for white after Bishop D for nine Central bishop 06:43.900 --> 06:44.890 Central Bishop pardon me. 06:44.890 --> 06:46.540 And then looking at a seven. 06:46.540 --> 06:51.280 So here this is going to be to White's advantage, this kind of end game. 06:51.640 --> 06:54.580 If we look at this again instead of king of free, if we took immediately. 06:54.580 --> 06:55.090 Sure. 06:55.090 --> 06:59.620 But it's not it's not as great as playing more positionally with king of free for the moment. 07:00.010 --> 07:02.410 But yeah, the resulting positions are not bad. 07:02.410 --> 07:07.480 Why It has to be able to invest though here to give a pawn back. 07:08.110 --> 07:15.400 So just to recap here, so a situation here with 93 and Mike takes five. 07:15.400 --> 07:18.010 The rookie is looking at E five and a two. 07:18.040 --> 07:24.480 You know, it is a complex position but if it seems if white gives back the pawn as a possession or 07:24.940 --> 07:30.310 a positional pawn sacrifice, this position is better for mine if white plays the cards right. 07:30.310 --> 07:31.090 But in the game. 07:31.090 --> 07:31.230 Yeah. 07:31.270 --> 07:39.700 Knight G five ruins things because if f five check 200 points if you cf5 check. 07:40.120 --> 07:47.080 So it seems to allow a non parsons but the on parsons, the thing is there's an unprotected rook on 07:47.080 --> 07:54.460 e one and we've just given amplification to that unprotected rook in that there's an accessibility now 07:54.760 --> 08:01.870 thing advantage as we have access to e one via knight takes g five with the express route gaining a 08:01.870 --> 08:04.930 tempo with the check rookie hack pick up the rook. 08:04.930 --> 08:13.750 Thanks very much if King free thanks very much there's folks 94 check 90 9c2 so yeah F five check ruins 08:13.750 --> 08:17.260 things king E free we have now. 08:18.310 --> 08:18.850 Yeah. 08:18.850 --> 08:22.210 So this, this is necessary to minimize the damage. 08:22.210 --> 08:23.680 Bishop C five check. 08:23.680 --> 08:25.690 And now White has to give up the exchange. 08:25.690 --> 08:31.750 If the king moves to e to Fulk, then pick up the exchange like that and Bishop takes F two and more 08:31.750 --> 08:34.120 carnage here like winning the rook. 08:34.120 --> 08:36.070 And you might think, Well, why didn't we move there? 08:36.070 --> 08:37.450 Well, we're going to win it like that. 08:37.450 --> 08:39.460 It's horrible the position. 08:39.460 --> 08:43.960 And if yeah, where does where does the king go free. 08:43.960 --> 08:45.670 There's still 94 check. 08:45.670 --> 08:49.090 So Black's position sprung into life to win material. 08:49.600 --> 08:49.990 Yeah. 08:49.990 --> 08:57.140 So we have we're having to give up the exchange nine takes and there's a bit of work to do here. 08:57.160 --> 08:58.500 This is kind of instructive. 08:58.510 --> 08:58.870 So. 08:58.870 --> 09:04.510 King a free plate If e six, we're just going to take on a two if E seven rook. 09:08.120 --> 09:10.460 Rook D Free is checkmate. 09:11.000 --> 09:12.980 Rook d Free is checkmate. 09:13.250 --> 09:14.300 Let's go all the way there. 09:16.460 --> 09:20.120 So because the rooks controlling the escapes wins the Queen king. 09:20.120 --> 09:21.530 So there's no time for Rook. 09:21.530 --> 09:22.640 Different is checkmate. 09:24.680 --> 09:27.620 And if King, If Free Knight takes be free. 09:27.620 --> 09:30.020 There's no problem here. 09:30.020 --> 09:31.580 The pawn can be stopped. 09:31.610 --> 09:34.240 There's no way of breaking that pawn through. 09:34.250 --> 09:44.690 So, yeah, we have King F3 and now King Fate Rook C1 And now there is potentially a threat of lurking 09:44.690 --> 09:51.560 of rook takes for 96 check 96 check for taking on C five. 09:51.560 --> 09:55.790 So that's addressed simply with King E seven rook C 93. 09:55.820 --> 10:01.040 We have Rook see six and Adams picks up E five swaps set for G six. 10:01.040 --> 10:06.530 So it seems as though, well, maybe White's kind of dismantle Black's pawn chain, but let's see. 10:06.530 --> 10:09.440 So King thinks there still work to do here. 10:09.440 --> 10:10.820 Rook d free check. 10:10.820 --> 10:16.940 King of four Now getting to the time control with some checks, avoiding free fold repetition. 10:16.940 --> 10:24.160 And now rook 85 Rook have seven checking E five check King D six rook eight seven rook d2. 10:24.200 --> 10:28.610 So Adams is going to try and get a pass pawn on this side of the board. 10:28.610 --> 10:32.360 Queenside So rook takes five. 10:32.360 --> 10:41.240 Rook takes a two 2 to 1 pull majority past pawn potential We have rook age six check kings 7h5a for 10:41.600 --> 10:50.780 a pass pawn race Rook 87 check 9796 check king see six rook takes DD seven King takes 8795 check King 10:50.780 --> 10:56.420 E seven The king is there to stop the pawn the h pawn runaway pawn As Nimzowitsch says, pass pawns 10:56.420 --> 10:59.420 like criminals to be kept under lock and key. 10:59.420 --> 11:02.750 You know, active surveillance is not enough by here. 11:02.750 --> 11:05.480 Yeah, we can actually stop this pawn. 11:05.480 --> 11:07.130 We have B takes a four. 11:07.130 --> 11:10.640 If Knight takes a fall, we can open the champagne bottle for the past. 11:10.640 --> 11:13.610 Pawn here with Rook takes a four and be free. 11:13.610 --> 11:14.870 We just queening. 11:15.290 --> 11:21.290 Okay, so B takes a four, but now rook C two might be free. 11:21.290 --> 11:22.160 Nine D free. 11:22.160 --> 11:26.540 And now if might be free, there's rook C free check. 11:26.930 --> 11:28.040 Just mentioned that. 11:28.460 --> 11:30.110 So yeah, this is hopeless. 11:30.110 --> 11:30.770 Basically. 11:30.770 --> 11:34.490 B be free end of game white resigns if H six. 11:34.490 --> 11:37.970 Yeah, we can take the time for King F six or B two is not going anywhere. 11:37.970 --> 11:40.730 We can stop this pawn with H seven king G seven. 11:41.060 --> 11:47.500 So let's see H seven, King G seven King F4 and we're playing B2 and that's absolutely winning. 11:47.510 --> 11:49.370 And by the way, yeah, we might as well. 11:49.370 --> 11:50.810 This is a safety point. 11:51.080 --> 11:53.450 It's good to be a perfectionist or not. 11:53.450 --> 11:56.390 Let the opponent have dangerous pass pawns. 11:56.390 --> 11:59.630 They are their winning probability of the opponent when they have passed pawns. 11:59.630 --> 12:03.230 So if we're taking the knight or taking the pawn, we can take the pawn with Shaq here. 12:03.260 --> 12:05.840 Get rid of the opponent's past pawns where possible. 12:06.530 --> 12:07.520 Yep. 12:07.520 --> 12:11.240 And that's absolutely winning for Black Oak. 12:11.570 --> 12:14.900 So, yeah, an interesting game in the Scotch game. 12:14.900 --> 12:15.950 Very, very interesting. 12:15.950 --> 12:17.610 White's king was aggressive. 12:17.630 --> 12:19.820 Slight downside of White's plan in general. 12:19.820 --> 12:25.280 White has to be careful about all the checks and forcing moves when one is trying to play like Wilhelm 12:25.280 --> 12:28.640 Steinitz following the motto that the king is an attacking piece. 12:28.640 --> 12:29.120 Yeah. 12:29.120 --> 12:35.900 So it's a very tricky business, even a pawn up, and it can lead to some complacency. 12:35.900 --> 12:36.530 So here. 12:36.530 --> 12:44.600 Yeah, not factoring in this F5 is an advanced form of, you know, a particular downside in White's 12:44.600 --> 12:45.140 plan. 12:45.140 --> 12:46.310 Positional plan. 12:46.550 --> 12:47.570 Okay. 12:48.080 --> 12:48.620 Yeah. 12:48.620 --> 12:55.490 So it's important to be looking at the forcing moves, even if you're a positional player and it's absolutely 12:55.490 --> 12:57.860 essential to win games tactics to win games. 12:57.860 --> 13:04.460 But positioning also can contain positional play, like trying to exchange off better pieces can contain 13:04.460 --> 13:06.380 total seeds of destruction as well. 13:06.380 --> 13:07.430 A bit of a warning note. 13:07.430 --> 13:12.740 Don't be too casual about this process of simplifying by trying to get rid of pieces. 13:12.740 --> 13:18.140 You've got to be careful about forcing moves all the time to look at the downsides of your own implementation, 13:18.140 --> 13:20.360 let alone the opponent's possession. 13:20.360 --> 13:23.210 So yeah, we find the downsides of our opponent's position. 13:23.210 --> 13:29.510 But when we have a plan in our moves, what the downsides of our moves, our implementation, and especially 13:29.510 --> 13:31.580 look at the forcing moves, the tempo gainers. 13:31.580 --> 13:36.830 So F5 just refutes it basically, and blacks on the path to victory after this. 13:36.830 --> 13:38.000 So a very interesting game. 13:38.000 --> 13:40.160 I hope you enjoyed this one as much as me. 13:40.370 --> 13:41.530 Very exciting. 13:41.540 --> 13:42.350 Thanks very much.
