WEBVTT 00:00.870 --> 00:01.560 Hi there. 00:01.590 --> 00:06.930 In this lecture, I'm going to show you an absolutely iconic game, Edward Laska, who some believe 00:07.050 --> 00:10.440 might be a relative of the great Emanuel Lasker. 00:10.470 --> 00:14.370 You know, a former world chess champion and we'll ask is still a very decent player. 00:14.400 --> 00:17.460 He's playing against George Allen Thomas in 1912. 00:17.460 --> 00:18.990 A casual game, believe it or not. 00:19.650 --> 00:27.390 Yeah, these casual games do get remembered sometimes, and this is actually featured on Netflix, the 00:27.390 --> 00:30.360 Explains series, which is a good series worth checking out. 00:30.450 --> 00:34.920 So anyway, D4 from Edward Lasker. 00:36.000 --> 00:39.450 We have a six from George Allen Thomas. 00:39.450 --> 00:41.780 So he wants to play actually a Dutch defense. 00:41.790 --> 00:48.390 Sometimes if you play the Dutch defense immediately there's the dangerous Staunton gambit, which gives 00:48.390 --> 00:49.890 many attacking perks. 00:50.280 --> 00:55.230 So anyway we see E6 and now it's a free F five. 00:55.230 --> 00:56.910 So at least there's no Staunton gambit. 00:56.910 --> 00:58.200 But there is 93. 00:58.200 --> 01:02.070 This is a nifty move quite often, and the positional threat is E4. 01:02.070 --> 01:05.730 Black kind of develops some parries that automatically might have stakes. 01:06.030 --> 01:11.180 That night is pins Bishop A7 And now this is a very interesting move. 01:11.190 --> 01:17.250 Bishop takes F6 often and even in neural network games where they beaten very strong engines, often 01:17.250 --> 01:22.110 giving up bishop for a point does lead to great pressure. 01:22.880 --> 01:27.800 On the other colour of the bishop, you've just given up because you've removed when you remove a knight 01:27.800 --> 01:29.240 and it's versatile. 01:29.270 --> 01:36.110 So sometimes you can statistically add more pressure than the opponent and here to the light squares. 01:36.110 --> 01:39.590 So more pressure has been added now to the light squares. 01:40.400 --> 01:46.220 So potentially this bishop can be involved in light squares, but also these guys potentially involved 01:46.220 --> 01:47.200 in light at square attack. 01:47.210 --> 01:53.270 So mathematically there's a kind of superiority which helps make successful attacks. 01:53.270 --> 01:56.870 Sometimes we have F tanks E for 9/10, E for. 01:56.870 --> 02:02.990 And of course this move my circles clears this diagonal, which could be very sensitive. 02:02.990 --> 02:07.790 We have Be6 Knight's E5 and Black has to tread carefully. 02:07.790 --> 02:13.870 Black Castled If Bishop takes E5, what has a nifty move here? 02:13.880 --> 02:15.110 Can you spot what that is for? 02:15.110 --> 02:15.920 Ten points? 02:17.470 --> 02:17.980 Yeah. 02:19.210 --> 02:25.210 Quinn H five check is stronger than 85 because then we're weakening squares here with interest. 02:25.210 --> 02:26.470 So this is very nice. 02:26.710 --> 02:34.570 If, for example, D5 Black's got some problems here positionally, if Quinn f6 okay, we could trade 02:34.570 --> 02:38.440 C seven for D for bluntly for White's overall better. 02:39.280 --> 02:46.990 So anyway, Black Consort and we have Bishop, the Free Bishop B seven, and now a very aggressive move. 02:46.990 --> 02:49.420 So this is this is the thing. 02:49.420 --> 02:54.130 The F6 Knight was defending a key light square and now there's an open invitation. 02:54.460 --> 02:55.120 Can you imagine that? 02:55.420 --> 02:57.940 There's an open invitation to get the queen near the king. 02:58.210 --> 03:01.210 This is a basic ingredient of attacking chess quite often. 03:01.480 --> 03:07.040 You know, when I won the Lloyds underwriting in 1989, I basically had this philosophy use my absolutely 03:07.060 --> 03:10.180 best resources on squares around the opponent's king. 03:10.300 --> 03:17.160 So this is a move which is totally justified in this opening sequence, and it's very dangerous. 03:17.170 --> 03:21.580 Black has to be careful about Knight takes F6 now and looking at H seven. 03:22.450 --> 03:28.720 So Black tries to do something about H seven here, but actually blundered terrifically. 03:29.890 --> 03:30.880 There are two moves. 03:30.880 --> 03:32.320 One is better than the other. 03:33.190 --> 03:34.630 One move is G6. 03:34.630 --> 03:38.530 But sure, this sorts out some of the problems. 03:38.530 --> 03:46.090 Queen E2 96 But why it should be better after nine takes F6 Rook takes F6 and it is possible for White 03:46.090 --> 03:53.860 Castle here with the x ray pressure on D seven justifying this tactic of of losing a pawn here. 03:54.130 --> 03:59.410 Queen Ephraim my five bishop takes rook taints. 03:59.410 --> 04:07.030 This ends up being a slightly better situation for white only slightly but there's a back move, actually. 04:08.100 --> 04:12.390 Bishop takes E5 and Y has to tread carefully. 04:12.390 --> 04:16.390 If D takes that loses a pawn, that's going to be slightly better. 04:16.410 --> 04:19.650 There is compensation for it, but it's not entirely great. 04:20.250 --> 04:28.920 So in fact, if this had occurred in this situation, white space is actually 92 and now black has to 04:28.920 --> 04:36.540 play a move like G6 because if Bishop f6, then this is a standard mate pattern. 04:36.870 --> 04:38.940 So Bishop G6, Queen 87. 04:38.940 --> 04:42.850 So let's imagine G6 Queen takes E5. 04:42.870 --> 04:44.310 This isn't even possession. 04:44.310 --> 04:47.940 So that's really what should have happened if Black was playing super accurately. 04:47.940 --> 04:51.570 But you can see why Black played this move. 04:51.600 --> 04:56.040 Perhaps expecting Knight takes f6 check when there is G takes. 04:56.130 --> 04:59.850 And you can see that actually resourcefully defends H seven. 05:01.320 --> 05:07.290 So defenders can feel that they're being resourceful but they might have missed a little trick and the 05:07.290 --> 05:14.940 black has missed the little trick here which is still an issue with H7 is a little bit of a clue. 05:15.090 --> 05:17.430 There's actually a force might in seven here. 05:17.520 --> 05:22.150 You might want to pause the video and work this out for a thousand points. 05:22.200 --> 05:24.060 Yeah, it's a beautiful one to work out. 05:25.200 --> 05:31.440 So once play absolutely forced noncontroversial sequence leading into champ mate. 05:32.300 --> 05:33.230 Believe it or not. 05:35.200 --> 05:36.490 I'm about to reveal. 05:38.180 --> 05:39.350 Queen size 87. 05:39.350 --> 05:42.200 Czech king size nine, Size F six. 05:42.200 --> 05:43.580 This is a double check. 05:43.730 --> 05:44.930 So the king has to move. 05:44.930 --> 05:46.340 That's the thing about double checks. 05:46.340 --> 05:49.100 If King H 896 is Chapman. 05:49.100 --> 05:56.450 So the king goes at 86 and the king is brought down the board here with this move my egg for Chuck. 05:56.540 --> 06:03.440 So the Kings only got one square and now H four check brings the King down the board. 06:03.560 --> 06:09.320 G three down the board and now Bishop E to check down the board. 06:09.350 --> 06:12.920 Now there's a choice of how to make the king here on G2. 06:13.490 --> 06:15.290 Rook h two check was chosen. 06:15.290 --> 06:21.830 Also quick is just castling because how does black defend against this or this? 06:22.460 --> 06:24.590 The king has come to our resources. 06:24.590 --> 06:27.320 This is a beautiful thing to get in chess. 06:27.470 --> 06:31.550 The king coming to us rather than our attacking resources going to the king. 06:32.300 --> 06:34.220 So, yes, this is just mating. 06:34.220 --> 06:36.950 This this one is mating or rook one. 06:37.070 --> 06:37.490 Right. 06:37.700 --> 06:44.210 So but anyway, in the game it was rook to check giving a choice of checkmate King D2 was taken and 06:44.210 --> 06:45.110 that is checkmate. 06:47.120 --> 06:51.170 There was also castling queenside if if that was preferred. 06:51.380 --> 06:52.370 But yes. 06:52.790 --> 06:54.620 So some lessons from this game. 06:55.160 --> 07:04.430 These are iconic games and with them it's good to search for the abstract elements. 07:04.430 --> 07:05.450 I find in my experience. 07:05.450 --> 07:10.340 I mean, one of my favorite findings is basically bishop of our counterpart, and that comes from looking 07:10.340 --> 07:15.710 at a lot of neural network games, actually how they're beating even the top and let's go engines. 07:15.710 --> 07:21.950 So there's something definitely even against tough resistance in a bishop about account spot. 07:21.950 --> 07:28.550 But here there is something abstract which I also noticed from even neural network wins against classic 07:28.550 --> 07:32.600 engines, which is giving up a bishop for annoyance. 07:32.660 --> 07:38.210 You end up quite often with a superiority on the other color. 07:38.660 --> 07:47.330 So here dot square bishop given up the night we get superiority sometimes on the light squares and conversely, 07:47.330 --> 07:53.150 if you give up a light squared bishop, you might get dark square pressure after it's something to celebrate. 07:53.150 --> 07:56.510 And I've seen celebrated in many neural network game examples. 07:56.510 --> 08:04.310 So this is an interesting pattern and we have many benefits here on this diagonal, dangerous practical 08:04.310 --> 08:05.150 benefits. 08:05.480 --> 08:10.820 So when I played a bit ambitious, they had to say the least, with Queen H five. 08:11.840 --> 08:20.060 So Black basically had to play Bishop thanks to E5 to test if whites can play 92. 08:21.500 --> 08:28.850 But yeah, we get this move, which, you know, was hopeful in 90 6f6 it seems, for G tanks, but 08:28.850 --> 08:35.180 then this false checkmate, you can see that the attack starts online squares at least. 08:35.510 --> 08:39.230 But yeah, the other key point, bringing the king to our resources. 08:39.710 --> 08:41.360 Yeah, that is a way of attacking. 08:41.360 --> 08:43.190 It's still the goal is met. 08:43.730 --> 08:49.100 When we attack, we usually think, yeah, traditionally we're heading towards the king. 08:49.100 --> 08:50.660 But what if the king came to us? 08:50.810 --> 08:51.980 Great stuff. 08:51.980 --> 08:53.570 I hope you enjoyed this game. 08:53.570 --> 08:56.600 And consider sometimes giving up a bishop for annoyance. 08:56.720 --> 09:01.490 The kind of bishop power was maybe given too much of a high regard. 09:01.490 --> 09:07.580 There's been many, many absolute classic winds literally giving up both bishops in classic games like 09:07.580 --> 09:12.230 immature against Kasparov, which will show in this course. 09:12.230 --> 09:18.230 So, you know, sometimes giving a bishop for a knight to get the pressure, see what it does, see 09:18.230 --> 09:19.070 what the France are. 09:19.070 --> 09:21.920 And sometimes, yeah, you get a spectacular win like this. 09:22.070 --> 09:25.490 So bringing the king down the boards for its demise. 09:25.580 --> 09:26.060 Okay. 09:26.060 --> 09:28.430 I hope you enjoyed that very much.
