WEBVTT 00:01.020 --> 00:01.830 Hi there. 00:01.860 --> 00:09.240 In this lecture, we see Aaron Nimzowitsch against Simeon Lapin in 1914 St Petersburg Tournament. 00:09.270 --> 00:10.020 Let's have a look. 00:10.050 --> 00:12.960 E-4 From the intervention, we have the French defence. 00:12.990 --> 00:21.710 D4 D5 and now 9396 E takes de 59635 Knights, F3 and now C5. 00:21.720 --> 00:27.210 This does expose black to tempo gainers from white. 00:27.630 --> 00:29.760 Now tempo gainers lead in developments. 00:30.090 --> 00:34.290 There sometimes temporary advantages if you don't actually capitalize on them. 00:34.590 --> 00:36.000 They will disappear. 00:37.630 --> 00:39.590 So it's it's an interesting decision. 00:39.610 --> 00:42.430 c5a safer one would have been Bishop E seven. 00:42.430 --> 00:52.090 So for example, Bishop defray nine, c3b tanks 97, Queen E 296 White can claim a small edge, but 00:52.090 --> 00:54.130 this is actually an inaccuracy here. 00:54.160 --> 01:04.420 C five The king is still in the center and it means this line of attack is sometimes dangerous as well. 01:04.420 --> 01:09.010 We have knight takes D five, queen takes D five is played. 01:09.010 --> 01:11.890 If e takes, we can use Bishop B five check here. 01:12.880 --> 01:15.790 Given that the pawn, there's no C six or anything. 01:15.790 --> 01:21.430 And this possession we can actually play Bishop takes these seven Czech queen takes these seven and 01:21.430 --> 01:28.000 just castling and we're better here For example here D take C five trying to get a tempo here Rookie 01:28.000 --> 01:34.600 one check Bishop E seven and we can actually convert the temporary advantage here into a more permanent 01:34.600 --> 01:35.220 one. 01:35.230 --> 01:39.700 Can you see how for ten points, what would you play? 01:41.810 --> 01:47.270 And we can actually gain the tempo first and in this position is black let off the hook. 01:47.660 --> 01:49.550 We need to convert the temporary advantage. 01:49.550 --> 01:52.580 If black castles, black might actually be okay. 01:53.330 --> 01:59.690 So what would you do in this situation to really amplify the temporary advantage before it disappears? 01:59.690 --> 02:02.930 We've got to amplify it to the extent it creates a permanent advantage. 02:03.500 --> 02:07.460 And there's actually a move here which is kind of crushing. 02:08.210 --> 02:10.190 So what is this move for 100 points? 02:10.280 --> 02:11.960 So this is just the variation of this game. 02:11.960 --> 02:13.010 It's fascinating. 02:14.470 --> 02:14.750 Okay. 02:14.850 --> 02:15.500 Bishop G. 02:15.500 --> 02:20.900 Five Offering material amplifies the temporary advantage before it disappears. 02:21.170 --> 02:27.470 So here, if Bishop takes G five, we'll play 96 check and advantageously win the Queen. 02:27.770 --> 02:29.000 So that's nice. 02:29.180 --> 02:33.590 And if f six, we can play Queen H five exploiting the king in the center. 02:33.830 --> 02:37.460 And here Knight takes g six is quite vicious, this position. 02:38.270 --> 02:39.740 Queen H Free check. 02:40.010 --> 02:41.480 Bishop four Check. 02:41.660 --> 02:46.280 Bishop 66 Check where Material up with a crushing position. 02:46.370 --> 02:50.840 So that's a great demonstration of E 65 going badly wrong. 02:50.930 --> 02:57.950 So Queen takes the five is played and now tempo gaining Bishop e three so not a standard move is actually 02:57.950 --> 03:05.090 threatening to win a pawn potentially you know with details and queen size. 03:05.240 --> 03:09.320 So C text is played Knight takes D four and now a six. 03:10.880 --> 03:16.400 And here Bishop E two black makes things far worse with Queen text G two. 03:16.700 --> 03:22.790 So a lack of development and the queen itself subject to great tempo gains. 03:22.790 --> 03:23.720 We have Bishop free. 03:23.720 --> 03:28.130 The Queen goes the G six, Queen DD two and E five. 03:28.130 --> 03:30.650 And here Nimzowitsch is truly amazing. 03:30.650 --> 03:37.160 Tactically, what would you play here to make sure you try and convert the temporary advantage into 03:37.160 --> 03:38.470 a more permanent one. 03:38.480 --> 03:40.010 That's the key question. 03:40.580 --> 03:47.450 So this position, sometimes we do need to sacrifice to get that conversion, to get to that threshold 03:47.450 --> 03:48.590 where there's a conversion. 03:48.920 --> 03:52.910 So what would you play for 100 points here with whites? 03:55.950 --> 04:00.390 Do we move the night course or the offer? 04:00.390 --> 04:04.140 The night, if night be free. 04:05.370 --> 04:06.490 Bishop E seven. 04:06.790 --> 04:09.720 We've lost most of our advantage here, actually. 04:10.110 --> 04:14.760 Black is on the way to just being slightly worse overall. 04:15.750 --> 04:16.890 I know we're two. 04:17.160 --> 04:18.600 We're two pawns up. 04:18.600 --> 04:19.260 Sorry. 04:19.350 --> 04:20.970 We're two pawns down. 04:20.970 --> 04:22.980 Rather, we're two pawns down. 04:23.790 --> 04:27.990 But even in this position, White still has some compensation. 04:27.990 --> 04:28.260 Why? 04:28.260 --> 04:29.580 It's only slightly better. 04:29.580 --> 04:33.960 But the way Nimzowitsch plays it, it's a much more dangerous conversion. 04:34.500 --> 04:37.110 Just leaving the knight to be taken by castling. 04:37.110 --> 04:38.910 And it is taken now. 04:38.910 --> 04:44.520 The thing is, on Bishop E seven we can gain a temporary of Rook G one and there's a fascinating move 04:44.520 --> 04:47.070 here, which maybe you'd never consider. 04:47.880 --> 04:50.730 This position is absolutely fascinating. 04:51.000 --> 04:53.360 We've got pressure on this diagonal. 04:53.370 --> 04:58.740 That's something to note as a slight clue, and it looks as though, well, we can't we don't want to 04:58.980 --> 05:00.090 have the Queen's coming off. 05:00.090 --> 05:00.840 There wouldn't be enough. 05:00.840 --> 05:01.500 Right. 05:02.130 --> 05:03.270 So what would you play here for? 05:03.270 --> 05:04.290 100 points. 05:06.060 --> 05:09.660 In this case, there is a move. 05:10.350 --> 05:10.470 Yeah. 05:10.550 --> 05:11.070 95. 05:11.070 --> 05:13.020 Embrace the Queen's coming off. 05:14.010 --> 05:17.050 An embrace, a weakness of the last move. 05:17.070 --> 05:19.200 If the bishop takes the night. 05:19.470 --> 05:20.610 It seems ridiculous. 05:20.610 --> 05:22.380 This is not about the king, right? 05:23.600 --> 05:26.190 It's about our glorious bishop power here. 05:27.330 --> 05:29.310 If Bishop takes her fight, we take on BB7. 05:29.310 --> 05:32.040 We're winning the rook, and we're getting loads of compensation. 05:32.250 --> 05:33.270 We're better. 05:33.750 --> 05:35.780 So that is absolutely fascinating. 05:35.790 --> 05:37.980 If Queen's C-7 were just going to take on G7. 05:37.990 --> 05:38.580 Thanks very much. 05:38.580 --> 05:39.450 That's crushing. 05:40.200 --> 05:43.140 So, yes, this is a really interesting continuation. 05:43.140 --> 05:49.530 Now, if the Queen has gone to F6, you know, Bishop G5 and then we can take on E seven. 05:51.150 --> 05:53.040 And let's say Queen takes seven. 05:55.040 --> 06:02.720 And yeah, there's a really amazing resource here to think about. 06:05.670 --> 06:06.240 Yeah. 06:08.240 --> 06:13.340 Bishop thanks B7 would definitely be converting our advantages. 06:18.630 --> 06:23.250 We've got all sorts of tricky resources here if Queen takes. 06:24.880 --> 06:31.090 We can consider quite seriously 96 keeping the king in the centre, for instance, in Queen D eight 06:31.330 --> 06:35.680 and as example Queenie seven doesn't help. 06:35.680 --> 06:45.040 We still have a glorious attacking position with moves like 90 6g7, Shaq and Queen H six coming. 06:45.040 --> 06:48.980 But let's have a look at Bishop takes B 795. 06:49.030 --> 06:50.490 This is also going to be glorious. 06:50.500 --> 06:53.890 9g7 Shaq Queen before it's just mating. 06:53.890 --> 06:55.120 It's just simply mating. 06:57.310 --> 07:02.740 So yeah, Bishop E seven does run into grave difficulties after G one. 07:02.740 --> 07:06.340 It shows the temporary, you know, lead involvement. 07:06.340 --> 07:12.930 We can capitalize on it with this stunning 95 hair or if Queen F six. 07:12.940 --> 07:19.120 Yeah, we can capitalize here convert that temporary into permanent with this amazing resource. 07:19.120 --> 07:20.650 Bishop thanks b seven. 07:20.650 --> 07:24.460 Really fascinating stuff. 07:24.460 --> 07:34.240 So e tanks is played and now we have Bishop tanks RD 490 C six and with the king in the center there's 07:34.240 --> 07:36.160 a really glorious move played in this position. 07:36.160 --> 07:41.200 There are several good moves that winning, but Nimzowitsch plays one of the most accurate, brilliant 07:41.200 --> 07:47.260 tactician, Nimzowitsch as well as great positional player into introduction of many top positional 07:47.260 --> 07:47.890 players. 07:47.890 --> 07:51.160 So what would you play here with White for 100 points? 07:53.170 --> 07:57.520 The most incisive move, Czech or chess? 07:58.630 --> 08:04.220 The so-called captures check all major threats like mating one or two and you might consider sex is 08:04.220 --> 08:05.330 kind of threatening. 08:05.330 --> 08:06.320 Queenly eight. 08:06.360 --> 08:06.740 Pardon me. 08:06.770 --> 08:07.460 It's threatening. 08:07.460 --> 08:10.400 Queenly eight to be mating. 08:11.360 --> 08:14.720 So it is a tempo gaining move. 08:14.960 --> 08:17.750 Bishop takes g seven is also strong here. 08:17.750 --> 08:19.880 This is like this is really dangerous. 08:19.880 --> 08:26.570 But this is even more emphatic in actually so Queen sex f six is played. 08:27.320 --> 08:34.340 If Bishop e seven we can take out c six to weaken the eight and then Queen D eight is nice. 08:34.910 --> 08:36.320 So Queen thanks is played. 08:36.320 --> 08:39.950 We have rook he1 check Bishop e seven. 08:43.730 --> 08:44.240 Yeah. 08:44.240 --> 08:48.050 And here, Bishop, take C sex check now. 08:48.260 --> 08:55.100 If B takes C six, then Queen RD eight is checkmate on King of Fate. 08:55.860 --> 08:56.120 Yeah. 08:56.120 --> 08:56.610 So this. 08:56.630 --> 08:57.380 This is the game. 08:57.380 --> 08:58.160 King of fate. 08:58.190 --> 08:59.150 What do you think? 08:59.180 --> 09:00.140 Nimzowitsch played here. 09:00.140 --> 09:02.450 Czech, all Czechs, even the most outrageous ones. 09:04.440 --> 09:05.520 Getting a tempo. 09:08.980 --> 09:10.090 Queenly eight. 09:10.120 --> 09:14.110 Check Bishop takes the eight are now rookie eight is checkmate. 09:14.950 --> 09:18.430 What a brilliant tactical game from the switch. 09:18.610 --> 09:21.580 So time is an important thing. 09:21.580 --> 09:28.690 But also if we're trying to accumulate advantages, sometimes the advantages are temporary in nature. 09:28.690 --> 09:36.880 We need to be great tacticians, sometimes to convert the temporary into more permanent advantages, 09:36.880 --> 09:38.530 permanent damage to the opponent. 09:38.530 --> 09:44.410 If we don't find the resources, sometimes we need to add more fuel to the fire by sacrificing pieces 09:44.410 --> 09:47.800 as this game shows this relatively short game shows. 09:47.800 --> 09:57.190 So yeah, it's it's very dramatic play to make that conversion of temporary advantage to more concrete 09:57.340 --> 10:02.680 advantages or champ meeting of course ends the game positional player or not checkmate ends the game 10:02.680 --> 10:10.590 as it did here so a real beauty of a game beautiful variations and showing how development, tempo or 10:10.600 --> 10:14.530 in general could be in the middle game in the opening or middle game. 10:14.530 --> 10:21.340 How we can try and convert with emphatic you know piece sacrifices for example into more permanent advantages 10:21.340 --> 10:22.690 So wonderful stuff. 10:22.690 --> 10:23.650 I hope you enjoyed it. 10:24.500 --> 10:25.250 And so much.
