WEBVTT 00:00.870 --> 00:01.620 Hi there. 00:01.650 --> 00:04.620 In this lecture, we see Alexander Alekhine against Hans Jona. 00:04.620 --> 00:09.690 In 1944, the Zurich tournament's round ten e4 from Alekhine. 00:09.690 --> 00:18.870 We see E5 from Jonah nine South free from Alekhine 96 A Roy Lopez asks Bishop a4 these things. 00:19.410 --> 00:23.640 So this is a Steinitz defense deferred this delay of d6. 00:23.820 --> 00:33.780 We have f6 C3 Bishop D7 d4, Bishop e seven and Alekhine does play D5. 00:33.780 --> 00:38.850 We have Knight B eight, Bishop C to Bishop G4 and now C4. 00:38.880 --> 00:41.550 There is a potentially bad bishop here. 00:41.550 --> 00:44.370 This C4 bishop in is hemmed in by its own pawns. 00:44.610 --> 00:47.850 Can this situation be resolved later in some way? 00:47.940 --> 00:51.330 Knight be the seven We have H3 Bishop age five. 00:51.840 --> 00:57.540 Knight C Free Black Castles, G4, Bishop g6 Queen E2 98. 00:57.540 --> 00:59.400 So it's a fairly closed position. 01:01.130 --> 01:04.880 Bishop D2 86 King G2. 01:05.060 --> 01:06.140 Bishop 87. 01:06.560 --> 01:08.750 But there's still some attacking prospects here. 01:08.750 --> 01:17.390 Rook H one And it looks as though if White's has some more moves, moves like H4 and maybe first H5 01:17.390 --> 01:23.450 to stop any counterplay before G5 that's sometimes used because otherwise, sometimes G5 h5. 01:23.450 --> 01:30.530 But anyway, Black is concerned and plays G5 h4 f6. 01:30.890 --> 01:32.680 We have Knight D1. 01:32.690 --> 01:39.110 This looks very logical to put a knight into F5, but we'll won't be left with this kind of bishop locked 01:39.110 --> 01:40.910 in in its own pawn structure. 01:40.910 --> 01:42.770 That's the key consideration here. 01:43.310 --> 01:48.140 Rook have 793978 and now Knight F five is played. 01:48.350 --> 01:50.600 Bishop takes out five G tanks. 01:51.470 --> 01:57.200 Rook H7 Rook egg 197 King F one Queenie 01:57.200 --> 02:03.080 89h2959g49 02:03.080 --> 02:05.660 f4 Queen F3 King G seven. 02:05.660 --> 02:11.030 So so far it seems as though there's this build up, but where is the actual breakthrough for White's 02:11.030 --> 02:18.800 in this position we see H takes g5h tanks, a pair of rooks come off so knight tanks, Rook H one, 02:19.670 --> 02:22.070 King H eight and now Rook H six. 02:22.070 --> 02:28.880 There seems to be kind of dangerous looking, looking at f6 Queen f7 Bishop D one So what's the point 02:28.880 --> 02:36.740 of this Rook G eight And the point here now is Queen B3. 02:36.770 --> 02:40.940 Yeah, Black is having to concede something here. 02:40.940 --> 02:50.120 It seems a weakness B6 if Rook b81 could play bishop thanks F4 and on eating sapphire can you see what 02:50.120 --> 02:54.350 white can play here which is actually rather dangerous for black. 02:56.450 --> 02:56.650 Okay. 02:56.780 --> 03:03.080 This bishop doesn't have to be so bad after C five if D takes Queen H free. 03:03.350 --> 03:13.430 And the problem here is actually that there's an E five break on the cards, which means that this bishop 03:13.430 --> 03:15.600 could actually come to this classic diagonal. 03:15.620 --> 03:19.040 So as an example, rookie E5. 03:21.050 --> 03:25.910 And if F takes there's 9/10 e5 that's no good after F6. 03:25.940 --> 03:27.140 No good for black hair. 03:27.830 --> 03:30.530 If Bishop if there's no G6 winning the Queen. 03:30.950 --> 03:34.970 But what does Black actually do if. 03:38.720 --> 03:44.990 If Bishop takes F6, Bishop C2 and look at seven rugby sevens 96 chance. 03:45.010 --> 03:47.150 So absolutely winning stuff. 03:47.180 --> 03:48.230 It's just brutal. 03:48.560 --> 03:51.530 So you can see the bishop is coming alive in some variations here. 03:52.610 --> 03:53.120 So. 03:53.120 --> 03:53.460 Okay. 03:53.510 --> 03:54.090 So yeah. 03:54.670 --> 03:54.940 Yeah. 03:54.950 --> 04:00.920 It does seem to lead to a situation where Wayne could play C5 and then later E5 for this bishop to come 04:00.920 --> 04:01.700 alive. 04:02.810 --> 04:11.780 Okay, so B6 is played Queen A4, and here we have Bishop of eight. 04:11.810 --> 04:16.460 Yeah, there are annoying moves in this position if Rook eight. 04:16.670 --> 04:20.900 There's potentially an invasive move. 04:21.380 --> 04:28.250 Queen D seven, which maybe Black was really concerned about for good reason here. 04:28.790 --> 04:35.680 So this bishop fate offers a six potentially, but at the moment the rock is here. 04:35.690 --> 04:37.580 But what about the knight folk? 04:37.790 --> 04:39.320 So what would you play here? 04:40.880 --> 04:46.640 So in fact, in this position and the guy actually just leaves the rook to be taken, he takes out that 04:46.640 --> 04:50.150 pawn, giving him a potential past, a pawn in endgames. 04:50.480 --> 04:57.350 We have Bishop takes H six Knights, eight, eight, six Queen G, seven Knight Saints, G eight King 04:57.380 --> 05:04.070 Tanks G eight Queens, The Aycock Knights F eight Here if Queen F eight. 05:04.070 --> 05:08.930 Just to show the end game scenarios, the Queen's could come off here. 05:08.930 --> 05:11.680 One could play b4 with the idea of a4a5. 05:11.690 --> 05:14.180 The king could try and come to this side of the board. 05:14.810 --> 05:18.230 But let's have a look at this scenario of c5d tanks. 05:19.070 --> 05:23.120 A five king Y could actually get the bishops quite aggressively like this. 05:24.560 --> 05:26.750 So Bishop C six first thing, a seven. 05:26.750 --> 05:30.380 So black has to play King B eight Bishop E5. 05:30.380 --> 05:35.420 And this situation, it doesn't matter because now D six there's this dangerous pawn there which is 05:35.420 --> 05:38.330 going to be a winning four one essentially. 05:39.530 --> 05:42.230 So the scenarios with Queen F eight are not that great for Black. 05:42.230 --> 05:49.920 So if eight is played, Bishop takes her four, he takes F for Queenie eight here. 05:49.940 --> 05:55.190 Bishop H five was plausible as well sitting on the position, but it's not as fun as what Alekhine played 05:55.190 --> 05:55.970 actually. 05:57.560 --> 06:02.990 So this situation, there's no like break through evident, but in the way Alekhine played it. 06:02.990 --> 06:03.230 Yeah. 06:03.230 --> 06:12.320 He's not waiting ages for a breakthrough with Queenie eight because actually G4 is played here Queen 06:12.320 --> 06:17.700 H five and it seems as though Black might have had a good shot here. 06:17.720 --> 06:19.730 Black played F3, which is not so good. 06:19.730 --> 06:21.200 It seems as free. 06:22.640 --> 06:28.910 So the point of G three if Queen H for G tanks, f to King takes F two black could establish a nice 06:28.910 --> 06:30.680 night on G5 at least. 06:30.980 --> 06:36.770 And even though White's got a small edge, you know, Black could put up quite a bit of resistance here. 06:38.620 --> 06:39.790 Black is two points down. 06:39.800 --> 06:41.410 You might think, Well, that's incredible. 06:41.470 --> 06:44.020 But yeah, the night could be kind of annoying. 06:44.020 --> 06:46.930 Coming maybe later to E5 the Queen, and that could be annoying. 06:46.930 --> 06:48.070 You know, there's possibilities. 06:48.070 --> 06:49.630 It's only a small handful white hair. 06:49.630 --> 06:55.690 But compared to the game after F3, we have Bishop A4. 06:57.300 --> 07:01.110 1987 and now Bishop C to night F eight. 07:01.200 --> 07:02.420 And guess what? 07:02.430 --> 07:05.730 Alekhine plays here now for ten points. 07:08.400 --> 07:12.600 So how many for the position between pieces and pawns is important. 07:12.900 --> 07:16.710 If I'm trying to just unrestrained the bishop, we have details. 07:16.740 --> 07:26.490 E5 if f tanks e5 the thing is f6 and here if Queen takes f6, Queen takes G4 check. 07:27.510 --> 07:28.740 King a7 Bishop e4. 07:28.770 --> 07:30.690 The endgame is going to be good again after white. 07:30.690 --> 07:34.350 It takes here The end games are good for white in this situation. 07:34.350 --> 07:35.370 For example, here. 07:35.460 --> 07:35.820 Yeah. 07:35.820 --> 07:42.030 White's doing really well in the endgame scenario and dominating the knight actually in this example. 07:42.570 --> 07:46.740 So okay, D takes is played, but now D six. 07:46.770 --> 07:58.470 This opens up the possibility for Bishop e4 only Bishop e4 two d5 so we have C5 if C6 what would you 07:58.470 --> 07:59.430 play with White's? 08:00.960 --> 08:02.960 You know, we just open up on this diagonal. 08:02.960 --> 08:04.050 We've see five. 08:04.710 --> 08:05.910 So this would be vicious. 08:05.910 --> 08:07.230 Bishop Free shank. 08:07.860 --> 08:12.300 Bishop E Sinks is actually really crushing because. 08:12.300 --> 08:13.200 965. 08:13.200 --> 08:14.310 What would you play here? 08:15.840 --> 08:21.000 Yeah, let's be for black can cannot accept two pawns on the six, Frank. 08:21.720 --> 08:23.190 This is just diabolical. 08:23.190 --> 08:31.140 Nor can black you know D seven coming up for Queenie eight Mason So this situation is diabolical. 08:31.170 --> 08:38.640 If we look at this with the two pawns like that, that's absolutely a winning possession with a 78 coming. 08:38.820 --> 08:44.640 But also if a 67 threatens Queenie as well as Queenie, it's just. 08:46.110 --> 08:47.350 And also Queenie. 08:47.430 --> 08:47.700 Seven. 08:47.700 --> 08:52.410 We've got mates here, so yes, that can't be accepted, that situation. 08:54.020 --> 08:55.100 So here. 08:55.850 --> 08:57.890 Yeah, this would be kind of winning G three. 08:57.920 --> 08:59.390 B take C five. 09:00.140 --> 09:06.140 Queen G one is Britain's Queen G puts an end to that counterplay and White's winning easily. 09:06.230 --> 09:12.230 So okay so black try C five Bishop e4 Queen D seven. 09:12.230 --> 09:16.160 And there is a weakness of the last move here which Alekhine uses expertly. 09:16.160 --> 09:19.310 So guess what that is to kind of wave a mating that. 09:20.650 --> 09:21.510 So what would you play? 09:21.520 --> 09:22.690 Would you play a Czech? 09:22.930 --> 09:23.920 Would you play it on the move? 09:23.920 --> 09:27.430 And this is in the Art of Checkmate Course. 09:27.430 --> 09:28.690 You'll see that decision point. 09:28.690 --> 09:29.470 Do you play a check? 09:29.470 --> 09:30.910 Would you cover escape squares? 09:30.940 --> 09:38.230 Often covering escape squares is quiet, but more effective because it kind of often makes tracks so 09:38.230 --> 09:42.280 much more effective as if they're threatening basically to make it so careful. 09:42.280 --> 09:45.040 Decision Point for the art of Checkmate here. 09:45.070 --> 09:47.050 What would you play here To end the game. 09:48.910 --> 09:54.460 Okay, so not the check, but Queen H Sex and Black has to run because of the check. 09:54.460 --> 10:00.490 Coming up, if we play the track immediately, then King G7. 10:01.570 --> 10:07.570 So no, we want to control the king more accurately, taking out escape squares to make this chain so 10:07.570 --> 10:08.530 much more deadly. 10:08.530 --> 10:09.820 So black resigns here. 10:09.820 --> 10:15.220 If King if queen takes six, let's look at Queen 66 first Bishop D5 check. 10:15.460 --> 10:19.450 So it's kind of Boden's make pattern except, you know, a queen instead of a bishop. 10:19.660 --> 10:21.550 So black would have to give up the queen. 10:23.800 --> 10:30.880 And what else if King f7 her bishop d5 Shank King an f6 drops. 10:32.230 --> 10:34.420 And with that E5 is much weaker now. 10:35.470 --> 10:39.280 But also if the Queen moves, there's another crisscross Bishop C check. 10:39.730 --> 10:46.510 And here actually Queen G6 check is absolutely wearing black, is totally tied down and can't handle 10:46.510 --> 10:47.680 this situation. 10:48.010 --> 10:49.180 It's overload. 10:49.450 --> 10:52.540 So taking out an and queen in here with G7. 10:52.660 --> 10:57.010 So a very interesting game showing harmony was established. 10:57.010 --> 11:00.570 This bishop was just broken out of its chains, of its shackles. 11:00.580 --> 11:07.440 It was liberated through these pawn sacrifices and the expert way of mating at the end with Queen H 11:07.450 --> 11:07.930 sex. 11:08.110 --> 11:15.010 So, yes, it was a situation throughout the whole game where Black was cramped without too much counterplay 11:15.700 --> 11:18.400 and Alekhine was building up the pressure. 11:18.790 --> 11:23.710 There may have been some better alternatives at some point for black, but yeah, overall a passive 11:23.710 --> 11:28.870 game and was, you know, punished in a great style by alekhine. 11:28.900 --> 11:30.610 Okay, I hope you enjoyed this one. 11:31.420 --> 11:32.200 Thanks so much.
