WEBVTT 00:00.840 --> 00:01.630 Hi there. 00:01.650 --> 00:06.330 In this lecture, we see Alexei Slavin, an international monster, playing against atoms in the 2010 00:06.330 --> 00:08.250 British Championship Round five. 00:08.460 --> 00:10.740 So D four from Slovenia. 00:10.740 --> 00:15.870 We have nights of 693, E six, and now E three. 00:16.410 --> 00:22.620 So this is an interesting opening system by white off after Bishop de France like cold Zuccotti system. 00:22.620 --> 00:28.800 So the college system or cold closes in the bishop, but the bishop often feign cantos later. 00:29.340 --> 00:31.770 So that's cold territory now. 00:31.770 --> 00:35.280 So we have D 595. 00:35.280 --> 00:41.460 Why is tempted to set up what looks to be an attractive knight on E five and it seems you know this 00:41.460 --> 00:44.280 this play by Adams the bishops biting on that knight. 00:45.540 --> 00:48.990 And you might think, well, that's interesting. 00:48.990 --> 00:53.250 But isn't White getting a nice attacking position here? 00:53.280 --> 00:56.220 Superficially, yes, you could say yes. 00:56.430 --> 00:57.930 But Adams is not worried. 00:57.930 --> 01:01.410 He Castles 92 and now see five. 01:01.830 --> 01:05.690 This is starting and undermining campaign now after be free. 01:05.700 --> 01:10.200 There's a great move for an undermining campaign of White's position. 01:10.380 --> 01:11.430 Can you see what that is? 01:11.430 --> 01:14.310 So we want to undermine the structure. 01:14.340 --> 01:16.800 The structure is on dot squares. 01:16.800 --> 01:19.430 If we can loosen and isolate pawns, that's good. 01:19.440 --> 01:23.280 But also think of the dark square implications around the board as well. 01:23.280 --> 01:30.090 That's going to be a perk of undermining the center and trying to destroy this dark square construction. 01:30.390 --> 01:36.900 So it is like a kind of stone wall structure as well, trying to get the bishop to be useful. 01:37.500 --> 01:44.790 But Adams plays B5, so there's an immediate idea of C4 to push the bishop back. 01:44.790 --> 01:45.870 Introduced. 01:46.020 --> 01:53.370 We have C three, so yes, C four could be answered by Bishop C two, but let's have a look at Bishop 01:53.370 --> 01:54.090 takes B5. 01:54.090 --> 01:55.170 This wasn't played. 01:56.190 --> 02:01.350 There's C takes the four E text and we see Queen B six being strong, just hitting B five and D four. 02:01.800 --> 02:07.590 So if White plays Bishop D three, we can see that the dark square impacts impacts losing a rook. 02:07.770 --> 02:09.180 So that's not good. 02:09.180 --> 02:16.950 In fact, let's say dr4 instead here a six Bishop d3d takes e three. 02:16.950 --> 02:19.170 This is going to be slightly better for black. 02:19.170 --> 02:22.920 We can see that Black has loosened White's dark square grip. 02:23.460 --> 02:31.710 So So C four is played on C phrase plate, but now carrying on the dance, undermining B four just seems 02:31.710 --> 02:32.430 very logical. 02:32.430 --> 02:35.160 Simple play C takes B four. 02:35.160 --> 02:39.120 If D takes C five instead, Bishop takes C takes B4. 02:39.150 --> 02:41.370 This doesn't look too good for white. 02:41.370 --> 02:43.050 Black should have a small edge here. 02:44.490 --> 02:51.930 Okay, so c tanks for we have c takes D for e takes and now white's pawn on default is kind of more 02:51.930 --> 02:52.710 sensitive. 02:52.710 --> 02:54.270 There's no pawn supporting it. 02:54.720 --> 03:00.960 So black already is doing quite well out of the opening, you could say here very well outside of the 03:00.960 --> 03:01.770 opening. 03:01.770 --> 03:06.510 Bishop B two we have nine, C six, Queen E two and our Queen B six. 03:06.510 --> 03:12.930 This seems extremely logical, natural play, putting more pressure on D four, df3. 03:12.930 --> 03:16.740 We have Bishop D six, A three. 03:18.450 --> 03:22.050 So yes, tempting some complications with Queen takes be free. 03:22.050 --> 03:25.770 Adams is not having any of that stuff. 03:25.820 --> 03:31.890 Doesn't want to give white counterplay in general and actually just plays a five For the record let's 03:31.890 --> 03:39.960 concretely entertain Queen take free White's can play rook ab1 here and if Queen b6a good move here 03:39.960 --> 03:41.040 is Rook fc1. 03:41.040 --> 03:45.180 And it does seem to have sufficient compensation for the pawn. 03:45.360 --> 03:50.850 It's as if White played a kind of positional pawn sacrifice against black. 03:50.850 --> 03:55.920 So for example, here, black could be in huge trouble just losing material. 03:55.920 --> 04:01.080 So let's improve things for black and be more sensible after. 04:01.080 --> 04:07.140 So instead of Queen C seven, which is just going to be absolutely losing off to Bishop B five. 04:07.140 --> 04:07.380 Yeah. 04:07.380 --> 04:11.250 So let's say here Rook AC eight. 04:12.090 --> 04:15.720 Bishop C Free Queen C seven. 04:15.840 --> 04:25.050 Bishop E 194 White can take on C six and after 95, if white gets black starts square, Bishop won't 04:25.050 --> 04:26.990 start square Bishop is not that bad. 04:27.000 --> 04:29.370 Say Bishop B for Bishop A five. 04:29.520 --> 04:31.620 It's just an even position here. 04:31.740 --> 04:38.550 So yes, this gives White's position life, counterplay and there's lots of opportunities along the 04:38.550 --> 04:42.450 way for Black to go wrong here after accepting that pawn. 04:43.200 --> 04:52.140 So yes, if we go back here, for example, here, if instead of 94 bishop eights, then take six, 04:52.140 --> 04:54.540 Bishop takes 95 here. 04:54.540 --> 04:54.750 Yeah. 04:54.750 --> 05:00.930 This is just going to be in White's favor, for example, here taking on B eight. 05:00.930 --> 05:02.580 And then there's a nasty pin. 05:03.060 --> 05:03.840 Ouch. 05:03.840 --> 05:06.390 And this is why it's got a big advantage. 05:06.390 --> 05:14.370 So safety point, if you want to play positionally, it's good not to give the opponent a gigantic initiative. 05:14.400 --> 05:15.620 Keep things simple. 05:15.630 --> 05:18.960 Think about your own positional pawn sacrifice is not the opponent's. 05:18.960 --> 05:25.260 So a five is played in the game, bypassing all of the complications involved in taking the pawn on 05:25.260 --> 05:26.130 Be free. 05:26.130 --> 05:27.660 So game on from here. 05:30.100 --> 05:34.960 We have Rook, AC one and now there's a great plan. 05:34.960 --> 05:35.930 Bishop takes E five. 05:35.950 --> 05:37.810 Yeah, This bishop wasn't really doing anything. 05:37.900 --> 05:40.090 Swapping off for a better piece F takes in. 05:40.090 --> 05:42.010 The point is, what's the point? 05:42.030 --> 05:46.030 Our positional temporary pawn sacrifice idea. 05:46.450 --> 05:48.130 So can you guess what it is? 05:48.550 --> 05:53.140 Trying to get rid of White's absolute best piece and keep this guy a prisoner. 05:53.920 --> 05:56.980 So what would you play here with black for 100 points? 05:58.120 --> 05:59.650 Test your positional play. 06:00.810 --> 06:02.010 What's the plan? 06:02.220 --> 06:02.970 What's the move? 06:02.970 --> 06:05.970 Rather, plan seems to be a bit long term for me, I'd rather say. 06:05.970 --> 06:06.900 What's the move? 06:08.730 --> 06:10.130 OC 94. 06:10.230 --> 06:11.400 Yeah, this is really nice. 06:11.400 --> 06:12.240 94. 06:12.870 --> 06:15.690 So that night is difficult to tolerate. 06:15.690 --> 06:17.790 It's actually taken losing. 06:18.030 --> 06:20.160 It's been a piece better place. 06:20.160 --> 06:23.340 Bishop in terms of harmony for the pawn structure. 06:23.550 --> 06:32.520 D Tanks we have G five if Queen takes E for 97 is really nice for black here. 06:32.520 --> 06:37.440 There's Bishop 86 so the queen can't go into RD free if Queen B one. 06:37.440 --> 06:38.250 Sure we can take on. 06:38.280 --> 06:38.670 Be free. 06:38.670 --> 06:45.900 But even better, we can just play slowly here a pawn down with this move. 06:45.900 --> 06:48.630 And for example here now nine and five. 06:50.300 --> 06:51.190 And we're going to be better. 06:51.340 --> 06:54.050 It takes DX four if we look at this again. 06:54.500 --> 06:59.940 And we could also play 9f5 immediately as well, though Bishop takes our free. 06:59.960 --> 07:01.670 We're still better with Black head. 07:01.670 --> 07:07.090 We've really undermined destroyed White's pawn center and a pawn up. 07:07.100 --> 07:09.230 So 9g5 is tried. 07:09.890 --> 07:16.830 We have Knight takes rd four, Bishop takes the four, queen takes the four, check King H one and then 07:16.850 --> 07:21.650 White perhaps felt they were doing a deep combination from way back after h six. 07:21.650 --> 07:25.940 So if Knight free blacks just going to play queen takes e five. 07:26.240 --> 07:29.900 And this just seems great for black because it is great for black. 07:30.110 --> 07:31.550 So Knight takes F seven. 07:31.550 --> 07:33.860 White is relying on a tactical combination. 07:33.860 --> 07:41.480 However within this tactical combination to exploit perhaps a slight downside of the Black's position, 07:41.600 --> 07:45.320 the implementation itself has a downside. 07:45.320 --> 07:51.740 So White is banking on tactics here of the rook takes F seven, rook takes F seven. 07:51.740 --> 07:58.190 There is a slight downside of this entire implementation, and it's called the back row after Rook takes 07:58.190 --> 07:59.030 B7. 07:59.030 --> 08:03.620 Guess what Adams plays here, which is end of game. 08:04.550 --> 08:07.250 This is a bit of a sting in the tail to say the least. 08:07.940 --> 08:10.490 It's queen a one check and it's mating. 08:10.670 --> 08:11.510 Ouch. 08:11.930 --> 08:16.460 So the queen is going to go in front somewhere and then it's just checkmate. 08:17.870 --> 08:22.370 This is quite a vivid, undermining example. 08:22.370 --> 08:27.350 And it's nice to have contrast to lower players, not just other super gems. 08:27.350 --> 08:30.620 When Adams is playing an IM, this is what can happen. 08:30.620 --> 08:33.770 It can look as though the I had like zero chance. 08:34.040 --> 08:37.760 So Adams did this to some IMS in this British championship edition. 08:38.000 --> 08:40.460 So this is one of the victims in this tournament. 08:40.460 --> 08:47.360 It just seems like a very simple, effective positional chess avoiding complications of queen. 08:47.360 --> 08:47.630 Thanks. 08:47.660 --> 08:48.470 Be free. 08:48.470 --> 08:57.140 Just sticking with a positional pawn sacrifice idea which helps undermine white structure severely gets 08:57.140 --> 09:01.640 rid of White's bad pieces and white centers been destroyed here. 09:02.060 --> 09:05.930 And yes, combinations might have a downside to them. 09:05.930 --> 09:09.590 So although there's a downside being exploited, you've got to look at your own implementation. 09:09.590 --> 09:15.680 So when you look for downsides in the opponent's position, is there also a downside in your implementation? 09:15.980 --> 09:20.900 You need to kind of try and falsify after in a longer game, there's time to try and falsify things 09:20.900 --> 09:24.110 to be extra careful for the opponent being super resourceful. 09:24.110 --> 09:29.510 But yeah, the Queen on DD four is looking at Queen aa1. 09:30.620 --> 09:32.840 Okay, I hope you enjoyed this example. 09:32.870 --> 09:34.820 Funny stuff has very much.
