WEBVTT 00:00.930 --> 00:01.650 Hi there. 00:01.680 --> 00:06.030 In this lecture, we see a very interesting game between Alexander Alekhine with the White Pacers against 00:06.030 --> 00:10.860 Frederick Sims in 1923, an exhibition game E4 from Alekhine. 00:10.860 --> 00:17.010 We have a Sicilian defense, 19 F3, 1936, and now a very unusual bishop E two from Alekhine. 00:17.190 --> 00:18.990 So what is the idea behind this move? 00:18.990 --> 00:29.700 We see e6 alekhine consoles d6 d4 c takes d4 Knight takes three four, 956 and now a very interesting 00:29.700 --> 00:31.860 concept indeed, Bishop F3. 00:33.580 --> 00:40.450 It looks as though the bishop's a target here, and we have 95 saying, you know, what are you doing 00:40.450 --> 00:41.440 with this, Bishop Jeffrey? 00:41.440 --> 00:47.430 And we have now just see for setting up a bureaucracy bone structure Now in terms of piece and pawn 00:47.440 --> 00:54.720 harmony, a light square bishop in this bureaucracy structure is sometimes not very nice. 00:54.730 --> 00:56.080 It's kind of locked in. 00:56.320 --> 00:58.390 So there's a few questions here to ask. 00:58.390 --> 01:00.340 If Knight takes C4, we can rule this out. 01:00.340 --> 01:02.770 There's Queen, a full check picking up the knight. 01:04.600 --> 01:05.770 If B six. 01:05.770 --> 01:06.580 This is interesting. 01:06.580 --> 01:11.200 If black doesn't snatch on Geoffrey, let's say knight, C free Bishop B seven. 01:12.700 --> 01:15.520 The bishop could actually elect to go back here. 01:15.520 --> 01:20.570 And Black has committed to to these pieces and there's actually an F4 threat here. 01:20.590 --> 01:28.240 So imagine this scenario and let's say Knight takes E4, the king still in the center, and that means 01:28.240 --> 01:31.180 actually Knight takes E4, Bishop takes E4. 01:31.630 --> 01:36.700 There is actually a very powerful move, C5, to exploit the king of the center here and the lose piece 01:36.700 --> 01:37.750 on E4. 01:38.930 --> 01:45.010 This would be a downside now of the black position punished with actually C5 if D takes Queen A for 01:45.010 --> 01:45.640 check. 01:46.510 --> 01:54.730 So here if D seven Knight 66 unveils an attack against the bishop and hits the queen and this is a great 01:54.730 --> 01:55.840 position for white. 01:56.050 --> 01:57.820 So yes, this is fun stuff. 01:57.820 --> 01:58.300 Indeed. 01:58.300 --> 02:03.220 If King is seven, then White is going to have tremendous compensation here with the king in the center. 02:03.700 --> 02:09.850 So, yeah, it's all like fun stuff If if the knights didn't take the bishop, basically. 02:10.090 --> 02:13.060 If Bishop seven let's look at this way of playing it. 02:13.060 --> 02:19.540 Knight C three It could transpose back into a standard proxy bind position with White having an advantage. 02:19.690 --> 02:25.600 But yeah, Black took up the option of taking the bishop queen. 02:25.600 --> 02:25.920 Thanks. 02:25.930 --> 02:26.650 I'm free. 02:27.070 --> 02:34.060 And we have a situation of attacking harmony, you know, ready for a really beautiful concept that 02:34.060 --> 02:39.880 a move on the queenside essentially could influence the kingside later, with a bishop glaring down 02:39.880 --> 02:45.730 the diagonal, we have Bishop E, seven Knight, C free black castles and now B3. 02:45.730 --> 02:48.310 So this is a proxy point with a difference. 02:48.310 --> 02:52.000 The Queen is already in an attacking place, it seems. 02:52.000 --> 02:56.140 We see 97 Black is addicted to attacking things on our free in this game. 02:56.290 --> 02:59.530 Bishop b2 but now OC 95 is not used. 02:59.530 --> 03:04.510 We have Bishop f6, Rook 8186 and now Queen G3. 03:04.510 --> 03:10.780 You can see that there's a convergence potentially on the G seven square, Queen C seven King H one, 03:11.080 --> 03:14.140 Rook D eight and now F4 is played. 03:14.140 --> 03:18.460 Funnily enough, there is actually another interesting move in this position. 03:18.460 --> 03:20.080 Very interesting tactical move. 03:20.290 --> 03:22.120 Can you spot what that is? 03:23.770 --> 03:30.310 So with the Queen on G3 in G7, there is a very interesting attacking style move for the King, which 03:30.310 --> 03:31.840 is Knight F five. 03:31.900 --> 03:33.310 It looks at D six as well. 03:33.310 --> 03:34.630 Looking at G7. 03:34.630 --> 03:39.130 If it takes then 95 and you can see that hold on. 03:39.430 --> 03:46.720 The Queen's attacked, the knights attacked black has only one move to stay in the game F four and off 03:46.720 --> 03:52.560 The queen takes her for this position You might think, well, is this worth a piece sack? 03:52.750 --> 03:54.310 Actually, it is this. 03:54.310 --> 03:58.180 This is a strong attack for white in this position. 03:59.440 --> 04:06.340 For example, Rook d5 Queen the rook g5 shank king of and the attack rages on here. 04:06.370 --> 04:13.360 This is well worth it this piece and again C5 here in this position actually dangerously opens up lines 04:13.810 --> 04:23.830 and say C takes these six rook tanks D6 rookie five check Bishop e6 rook thanks e6 check f tanks e six 04:25.240 --> 04:32.770 Queen G seven is checkmate and if rook takes e6 Queen G five check this position. 04:32.770 --> 04:33.850 White's winning the Queen. 04:33.850 --> 04:43.000 So anyway, five in a nutshell does seem like a very interesting move in g7d6 is a very interesting 04:43.090 --> 04:44.080 piece sac. 04:44.560 --> 04:50.950 So anyway though F4 is played, we have B6, which actually makes things a lot worse as we're about 04:50.950 --> 04:52.930 to see F5 now. 04:52.930 --> 04:58.600 Sometimes you think of moves as having up and down sides, Oh, it's giving up the E5 square, but you've 04:58.600 --> 05:02.320 got to prove your upside space in the in the follow up in the continuation. 05:02.320 --> 05:09.760 And there's absolutely a phenomenal follow up here for weakening for that so-called downside or cost 05:09.760 --> 05:11.140 of, of playing F5. 05:11.370 --> 05:12.760 There's a phenomenal follow up. 05:12.760 --> 05:14.590 So Bishop E5 is played. 05:16.540 --> 05:18.320 But what else if E5? 05:18.340 --> 05:21.840 Then there's Knight D5 again, That's a really nasty hit on the Queen. 05:21.850 --> 05:25.490 And here actually there would be a very strong tactical move. 05:25.510 --> 05:27.490 Can you spot it for ten points? 05:28.390 --> 05:30.010 Let's try and rip open things. 05:30.910 --> 05:33.940 Especially this rook, which is a bit kind of restricted. 05:33.970 --> 05:37.540 We can play 96 here in this situation. 05:37.540 --> 05:43.020 If F takes it's ripping open activity for the rook. 05:43.030 --> 05:45.460 So here Knight takes f6. 05:45.460 --> 05:46.900 Jack, this is just diabolical. 05:46.900 --> 05:52.840 Knight takes 87 and there's a hook on F7 to exploit. 05:52.840 --> 05:58.060 So 9687 rook F seven is absolutely crushing for Queen takes D7 mate. 05:58.060 --> 06:05.080 So yes, E5 really doesn't help Black's cause off the 95 and this situation if Rook e eight her knight 06:05.080 --> 06:08.590 takes six check and then Queen 67 is mate. 06:08.590 --> 06:17.410 So anyway Bishop E5 is tried so for 1000 points and if you can work it out you get if you work it out, 06:17.410 --> 06:20.770 you get one faster boys, what would you play in this position? 06:21.040 --> 06:26.260 So the downside downside of our F5 move is trying to be exploited with Bishop E5. 06:26.260 --> 06:28.630 What do we have to say in the follow up here? 06:28.660 --> 06:30.010 Do we move on, Queen? 06:32.410 --> 06:33.760 Or do we do something else? 06:38.890 --> 06:41.410 What makes this game phenomenal here? 06:42.530 --> 06:45.560 Is that f takes a sexist blade, sacrificing the queen 06:48.800 --> 06:49.490 Just well. 06:49.520 --> 06:53.110 Bishop takes G Frank if f six. 06:53.150 --> 06:54.760 Let's have a look at this from Rook. 06:54.770 --> 06:56.360 Takes F six as possible. 06:56.720 --> 07:00.350 Bishop takes Geoffrey Rook takes F seven as possible. 07:00.440 --> 07:09.530 And this position is phenomenal with a four hitting the queen F3 hitting the Queen again and we can 07:09.530 --> 07:12.530 cash out with Rook tax g seven here. 07:13.040 --> 07:14.740 And this is just winning for one. 07:14.750 --> 07:21.290 This position is just winning for white, say 1968. 07:21.380 --> 07:23.720 H takes even though white is the exchange down. 07:23.720 --> 07:26.810 There's just so many pawns for Benny's change down. 07:26.810 --> 07:28.220 It's a huge number of pawns. 07:28.220 --> 07:29.690 It's just better for Waynes. 07:29.690 --> 07:36.050 So this is a very interesting scenario where it is just better for white If King takes down as things 07:36.050 --> 07:37.700 like 96 check. 07:37.940 --> 07:47.060 So this is just better for white if f takes e6 instead of taking the queen noit E6 is possible. 07:47.090 --> 07:49.460 Bishop takes G4 in 1967. 07:49.670 --> 07:54.320 This situation with h takes rook saying c seven there's 95. 07:54.350 --> 07:59.300 It's a very powerful situation for white for example, like this with the default being in trouble for 07:59.300 --> 08:01.280 black, huge advantage for Wayne. 08:01.280 --> 08:03.530 So the Queen sacrifice is accepted. 08:03.590 --> 08:06.920 We have eight x, f seven check and now King H eight. 08:06.950 --> 08:11.870 If King F eight, then there's 96 check and white can win the Queen. 08:12.470 --> 08:15.500 And in this position white's just much better. 08:15.890 --> 08:17.930 So that's out of the question. 08:18.770 --> 08:20.180 So King H eight. 08:22.610 --> 08:23.840 So in fact. 08:25.750 --> 08:26.050 Yeah. 08:26.050 --> 08:31.690 We're coming to the end of the game here with 95 Black actually resigned in Pretty. 08:31.780 --> 08:33.670 So he resigned here. 08:34.180 --> 08:37.060 So why this does require some explanation. 08:37.420 --> 08:39.050 If Queen a seven. 08:39.070 --> 08:40.660 Let's look at Queen 87. 08:41.170 --> 08:42.370 There's 96. 08:42.370 --> 08:44.930 That weakening of C six plays a role here. 08:44.950 --> 08:52.690 Funny enough, because now Queen B seven night takes day, knocks out a key defender of the square with 08:52.690 --> 08:54.080 tempo against the queen. 08:54.100 --> 08:57.190 So 4f8 crashing through for a back row mate. 08:57.970 --> 09:04.240 If Queen B 796 and one is black do here. 09:04.240 --> 09:09.310 If h thinks the front is actually bishop tanks g seven mate here. 09:09.550 --> 09:10.630 It's kind of serious. 09:10.630 --> 09:20.950 So eight six to give the king H seven but now Knight 68, Queen 87 and here knight F six, check Knight 09:20.950 --> 09:24.610 takes f6, Bishop takes f6. 09:25.120 --> 09:29.650 And how is Black actually stopping far cleaning here? 09:29.950 --> 09:38.350 It seems very difficult if black gives up the Queen and we just clearly Ben-Hur if Queen B 896 and this 09:38.350 --> 09:44.800 is just running with Tempo 1968, and if black's going to give up the Queen, it's hopeless. 09:45.040 --> 09:47.490 So, yes, a crushing end, just 95. 09:47.500 --> 09:51.730 It's a very interesting game from so many angles. 09:52.000 --> 09:58.180 The offering of the E to Bishop on her free from Roxie bone structure, which created great attacking 09:58.180 --> 10:00.610 piece harmony for the pieces. 10:01.050 --> 10:08.500 The square bishop was something just given up to get a fantastically coordinated position. 10:08.500 --> 10:16.660 What a phenomenal concept from a weird rare move just offering the bishop and just setting up the rock 10:16.660 --> 10:23.170 C binds saying goodbye to the Bishop, which would have been a non harmonic kind of piece with pieces 10:23.170 --> 10:24.730 and pawns in harmony. 10:24.730 --> 10:25.510 You want them in harmony. 10:25.750 --> 10:30.880 There's a really beautiful harmony and there's a really beautiful story here of the downside of playing 10:30.880 --> 10:34.270 for F4 F5. 10:35.350 --> 10:37.300 It's about king safety. 10:38.470 --> 10:40.450 So yes, it's in the follow ups. 10:40.450 --> 10:44.220 We can prove that actually it's well worth it that F5 is played here. 10:44.230 --> 10:45.700 What a fascinating game. 10:45.700 --> 10:47.830 I hope you found this as fascinating as me. 10:48.670 --> 10:49.450 Thanks very much.
