WEBVTT 00:00.870 --> 00:01.650 Hi there. 00:01.680 --> 00:05.040 In this lecture, we see Alexander Alekhine playing against Vlasic. 00:05.040 --> 00:09.210 In 1931, a simultaneous display E4 from Alekhine. 00:09.210 --> 00:18.780 We have a French defence from Wasik d4 d5 nine C3 Bishop Before now Bishop de and Black Volunteers Dance 00:18.790 --> 00:19.350 Square Bishop. 00:19.350 --> 00:25.860 This is actually not really an appropriate move giving why a dangerous bishop without our counterpart. 00:25.890 --> 00:32.760 These extreme imbalances, these differences in advantages where there isn't a dance bishop means that 00:32.760 --> 00:38.520 these squares are going to be particularly sensitive potentially, and in fact H six is played, which 00:38.520 --> 00:49.320 doesn't really help blacks cause maybe it was against the possibility of not wanting to be pinned on 00:49.320 --> 00:49.680 me. 00:49.680 --> 00:57.420 So for example, F6 we can see that Bishop G5 would be an annoying pen, but it's not helping King safety. 00:57.660 --> 01:05.070 The king still stuck in the center here and we have Bishop A3 now Black plays Knight. 01:05.070 --> 01:10.110 D7 This is curious now why is it Black playing 97? 01:10.110 --> 01:18.300 So at least try and console Well, if this happens, it is actually a good move. 01:19.410 --> 01:27.000 And if Knight takes D5 then Black on Castle again 9297 C for 97. 01:27.010 --> 01:33.450 Let's assume this position does have a big advantage even if black consoles this bishop here is rather 01:33.450 --> 01:34.200 dangerous. 01:35.250 --> 01:44.280 And if Knight thinks instead of 1965, if he takes the E5 93 and black consoles here, we still have 01:44.280 --> 01:45.570 attacking potential. 01:45.570 --> 01:47.520 We have this dangerous bishop. 01:47.760 --> 01:57.030 And in this situation it seems as though 1984 is a very dangerous idea with the idea of controlling 01:57.030 --> 01:59.280 key squares and pushing with the f pawn. 01:59.610 --> 02:01.290 This would be a strong attack. 02:01.290 --> 02:11.100 And for example, G4 is even possible where black's under great pressure if G5 because otherwise it's 02:11.100 --> 02:17.340 kind of very scary to now F5 and then queenside G4. 02:17.370 --> 02:18.870 This is very scary for Black. 02:19.860 --> 02:25.050 If Knight takes those knight takes that would safeguard that knight on age four and win a piece. 02:25.050 --> 02:27.600 So black's being pushed back here. 02:27.690 --> 02:30.810 So this shows this bishop is playing an instrumental role. 02:30.810 --> 02:35.430 Even if black castled there basically be a strong attack potential. 02:37.170 --> 02:45.390 So anyway, the king was actually left in the center and we have Queenie to D takes E4, Bishop takes 02:45.390 --> 02:49.620 E4, Knight F6 Bishop D3. 02:49.830 --> 02:54.810 Now the king is in the sensor and this quite often means there's bouncy roads of attack. 02:54.810 --> 02:59.070 With the king's still in the center, there's more than one diagonal of death. 02:59.520 --> 03:02.520 There's this diagonal potentially, and there's this diagonal. 03:03.390 --> 03:10.410 So if Black did manage to castle, you know, the diagonal death would be G When you castle Queenslanders, 03:10.410 --> 03:13.110 why the diagonal of death is often this diagonal. 03:13.140 --> 03:18.180 These key diagonals are often winning games daily for online games. 03:18.180 --> 03:20.220 Basically it's like a default. 03:20.790 --> 03:25.050 Losing liability You've got to play accurately around these. 03:25.080 --> 03:28.230 These liabilities is like skating on thin ice. 03:28.230 --> 03:29.670 So anyway, bear that in mind. 03:29.670 --> 03:30.840 But the king is in the center. 03:30.840 --> 03:33.630 So there's two like bouncy roads of attack here. 03:33.630 --> 03:35.970 Potentially we see B six. 03:36.450 --> 03:41.550 Now what do we want to play a bog standard move by or is there something stronger here for 200 points? 03:41.550 --> 03:44.280 What would you play in this position? 03:47.240 --> 03:48.830 And as a beautiful move indeed. 03:48.830 --> 03:54.950 Shaquille checks even totally outrageous ones because they represent forcing move possibilities. 03:54.950 --> 04:00.170 And as humans we can guarantee then the response is much, much more likely. 04:00.170 --> 04:04.190 Response is if we're really forcing the opponent into limited options. 04:04.190 --> 04:10.670 So yes, if you check out the outrageous Queen 66 and check out the weaknesses of the last move, so 04:10.670 --> 04:12.260 f takes E6, what is it? 04:12.260 --> 04:13.970 Weaken it weakens G six. 04:14.600 --> 04:15.080 Yeah. 04:15.080 --> 04:17.240 Bishop G six is checkmate. 04:17.750 --> 04:19.070 What could Black have done? 04:19.430 --> 04:20.960 Not much really. 04:20.960 --> 04:23.750 Queen E seven There's Queen takes E7. 04:23.750 --> 04:24.380 Checkmate. 04:24.410 --> 04:25.940 So a very cute one. 04:25.940 --> 04:27.320 One of my favorites. 04:27.470 --> 04:30.980 Little Alekhine games actually. 04:30.980 --> 04:34.010 But you know, it demonstrates a few things. 04:34.010 --> 04:39.140 Bishops without counterparts are often in some of the most celebrated games of chess, like the Morphy 04:39.140 --> 04:43.910 Opera game, where Morphy's opponents gave Alliance Square bishop with our counterpart. 04:43.910 --> 04:49.160 But here, you know, this dark square bishop we have a crisscross checkmate. 04:49.550 --> 04:54.020 So Bohdan checkmate where both bishops are participating. 04:54.020 --> 04:57.500 One bishop is covering escape squares, the other is mating. 04:57.500 --> 05:03.980 But the theme, the more broader theme from the perspective of this course is the king left in the center, 05:03.980 --> 05:05.600 casually left in the center. 05:05.600 --> 05:11.300 But the advantage is building up around the king in the center make it much more easy to exploit that 05:11.300 --> 05:11.930 king and center. 05:11.930 --> 05:17.240 The the bishop cutting across clearly the squares and stopping the king from castling. 05:17.240 --> 05:20.330 So a knockout blow early in this game. 05:20.450 --> 05:23.600 I hope you enjoyed this one as much as me and too much.
