WEBVTT 00:00.780 --> 00:01.620 Hi there. 00:01.770 --> 00:07.130 In this lecture, we see Alexander Alekhine playing against Edgar Colley in 1925, Paris Tournament, 00:07.150 --> 00:08.070 round six. 00:08.220 --> 00:16.140 We see d4 from Alexander Alekhine d5 C4 now Chigorin Defense named after Mikhail scoring and the adopted 00:16.140 --> 00:17.910 father of the Soviet Chess school. 00:18.060 --> 00:23.850 910 three Bishop G force a very interesting idea of giving up a bishop for a knight here Queen A4 is 00:23.850 --> 00:27.630 played Bishop takes our friend now Alekhine plays e6 F3. 00:27.630 --> 00:29.940 It seems this might actually be an inaccuracy. 00:30.510 --> 00:38.100 G takes f4 is actually plausible if D takes C4 just to play knight C3 offering D4 is very dangerous 00:38.100 --> 00:45.660 for black if knights f6 E3 and this is going to be pretty pleasant for White's and you might ask, well, 00:45.660 --> 00:48.450 what about Queen 64 Free pawn isn't it? 00:49.110 --> 00:51.270 Bishop E3 What does black play? 00:51.540 --> 00:53.130 If Black plays Queen D seven? 00:53.130 --> 00:54.870 Black is asking to be obliterated. 00:54.870 --> 01:03.330 Rook D1 and this position F4 with the idea of Bishop G2 coming up is huge pressure on black and E6 and 01:03.360 --> 01:06.060 we're just going to take on C6 and that's going to be crushing. 01:06.060 --> 01:12.480 If black's compelled to do something like King f7, then that's pretty miserable here. 01:12.480 --> 01:13.290 Indeed. 01:14.820 --> 01:22.200 So anyway, but these variations, if we're being a bit more careful with Black Queen E5, Bishop G2 01:22.200 --> 01:26.520 anyway, if Queen A5 just taking off the Queen's and White's Bishop parents good night. 01:26.520 --> 01:30.900 B5 is actually going to win a pawn back and then Knight B5. 01:30.900 --> 01:32.370 This is a small edge for white. 01:32.790 --> 01:33.960 You might ask. 01:33.960 --> 01:34.950 Well, what about castling? 01:34.950 --> 01:39.090 Queenside here this is asking for big trouble A4 we can play. 01:39.090 --> 01:40.020 What would you play here for? 01:40.020 --> 01:40.920 Five points. 01:42.910 --> 01:45.780 Yeah, we can just take on C six here and that's just wedding material. 01:45.790 --> 01:47.500 So it shows some of the dangers here. 01:47.500 --> 01:53.350 Basically, in a nutshell, G takes F three seems plausible and a very accurate move it seems, but 01:53.350 --> 01:55.000 e takes Afri was played. 01:55.030 --> 02:02.770 We have e nine C4 in our bishop before perhaps black does better actually to take on C4 in in this case 02:02.770 --> 02:11.170 to be greedy here is more justifiable if in the case of bishop take C4 queen. 02:11.170 --> 02:17.740 Thanks D for Bishop e Frank Windy Southern rook d one bishop sex. 02:19.090 --> 02:22.150 I mean, this should be an even position here. 02:23.570 --> 02:29.180 But yeah, there is pressure on black, but overall it looks as though blacks should be able to hold 02:29.180 --> 02:29.700 on here. 02:29.720 --> 02:32.600 But Bishop, before his plate, we have a free bishop. 02:32.600 --> 02:41.480 S.C. Frank B tanks like G seven, rook B one Rook B ain't So what has this bishop pair against the knight 02:41.510 --> 02:41.700 pair? 02:41.720 --> 02:43.820 How does Alekhine treat this position? 02:43.820 --> 02:46.130 It's interesting imbalance here. 02:46.220 --> 02:48.170 See tanks D Five queen tanks. 02:48.170 --> 02:52.790 D five Bishop D3 Now both sides Castle, Queen D six. 02:53.240 --> 02:55.160 Queen C two Knight G six. 02:55.400 --> 02:56.750 We have to move F fourth. 02:56.750 --> 03:01.220 So this is made possible because of the pressure on h79c7 is played. 03:01.250 --> 03:06.380 If Black does take if we look at Bishop takes h seven check, this is not worth the damage around the 03:06.380 --> 03:17.720 king Y is significantly better here so ce7g Free Rook 58 wrote d1b6 and he fought now 95 Bishop D2 and 03:17.720 --> 03:18.800 now C5. 03:19.010 --> 03:26.750 It seems black's doing fairly well actually right now at five E takes Bishop takes her five C to 64. 03:26.750 --> 03:33.350 So giving alekhine the isolated Queen's pawn, we have 97 here. 03:33.350 --> 03:39.710 It does seem as though h six was an interesting move if Bishop h3 Knight f eight it looks as though 03:39.710 --> 03:43.310 this is just equal, this possession it should have been. 03:43.820 --> 03:47.060 There should be a good for drawing. 03:47.060 --> 03:48.110 This is absolutely fine. 03:48.110 --> 03:55.130 Black's pretty solid with that blockading knight on D5 but in the game 97 this allows a forcing move 03:55.130 --> 04:02.360 bishop before and this is not the only good move Bishop H Fair was also good if Queen takes D4. 04:02.360 --> 04:08.840 The point is Bishop F4 here and that's hitting the Queen and hitting the rook. 04:08.840 --> 04:14.060 And this leads to an advantage for white with careful play here this position the car for move is Queen 04:14.060 --> 04:20.690 C seven and what ends up with a significant advantage not king takes H free because this is actually 04:20.690 --> 04:25.180 a actually significantly more favorable black. 04:25.220 --> 04:28.160 Black's should be able to hold here with equality. 04:28.160 --> 04:36.330 But okay anyway Bishop before was played not Bishop H3 and we have Queen f6 and now Bishop takes E7, 04:36.860 --> 04:37.970 Queen takes E seven. 04:37.970 --> 04:42.620 So giving up the dance Queen Bishop often means extra pressure on the light squares. 04:42.620 --> 04:45.710 So one of the knights taken out of the equation to hold light squares. 04:45.830 --> 04:55.610 So Rook goes to C one BC one we have rook d5, bishop e4, rook D7 and now D5 Queen up six and now Rookie 04:55.610 --> 04:55.790 one. 04:55.790 --> 04:57.530 This is a little bit naughty. 04:57.530 --> 04:59.090 It's looking at that back row. 04:59.090 --> 05:02.990 Actually, it's X-raying the potential of an entry on E eights. 05:02.990 --> 05:08.690 Bear that in mind Rook B to the eight we have Queen C6 and now Queen G5. 05:08.870 --> 05:16.610 If Queen takes C6 here D takes this position is actually favorable for white with a five. 05:17.030 --> 05:22.370 So that's structural damage rook b one and an entry point created b seven. 05:22.370 --> 05:25.640 This position with Rook A1 is a small edge for Waynes. 05:25.640 --> 05:30.410 So anyway, Queen G five we have now giving up the other bishop. 05:30.410 --> 05:34.520 Bishop takes G6 and Black is in a very dangerous position here. 05:34.760 --> 05:35.810 H takes was played. 05:35.810 --> 05:40.670 This is the intuitions captured towards the center, but the intuition needs to be challenged with King 05:40.670 --> 05:42.170 safety considerations. 05:42.170 --> 05:50.960 Black actually had to play, it seems, in a different way with f tanks not Queen takes. 05:50.960 --> 05:52.400 We can rule that out. 05:52.580 --> 05:53.990 What would you play here for? 05:53.990 --> 05:54.860 Ten points. 05:55.280 --> 05:57.590 Look at that rook naughty looking at E eight. 05:57.590 --> 05:58.280 That's a clue. 05:58.310 --> 05:59.930 So what would you play here? 06:00.680 --> 06:04.220 Check all checks, check all CAPTCHAs, Check all major threats of mating. 06:04.220 --> 06:05.120 One or two. 06:05.900 --> 06:08.470 Yeah, we played just queen tanks D seven head. 06:08.480 --> 06:11.390 Getting rid of that defender and rookie eight is a back row mate. 06:11.390 --> 06:16.580 So if stakes had to be played and it seems as though this is a critical line, Queenie eight Shaq and 06:16.580 --> 06:19.370 Rook have seven has to be played if King H. 06:19.580 --> 06:20.150 Yep. 06:20.150 --> 06:21.140 What are we playing? 06:21.320 --> 06:24.560 Yeah, Queenie, back row again. 06:24.800 --> 06:31.910 So this position, it seems the critical move here is actually Rook eight and this leads to a position 06:31.910 --> 06:39.140 where basically off the rook here one is better, but there's a bit of work to do. 06:39.140 --> 06:46.100 So this is certainly a position which, you know, it's dangerous to say it's D7, it's a position which 06:46.370 --> 06:51.740 should be in a great position, but there's work to do here. 06:51.860 --> 06:56.720 But in the game H takes was played and this is very different now. 06:56.780 --> 07:00.410 A beautiful combination from this position is available. 07:00.860 --> 07:02.510 Can you see what that is? 07:03.050 --> 07:04.310 It needs a precise move. 07:04.310 --> 07:05.030 Order. 07:05.360 --> 07:06.950 So what would you play here? 07:09.380 --> 07:12.110 So the double pawns around the King. 07:13.880 --> 07:18.020 Any form of structural damage is often interesting for for mating implications. 07:18.020 --> 07:19.430 The double pawns around the king. 07:19.430 --> 07:20.930 Are they a problem here? 07:21.050 --> 07:22.340 So you might want to pawn. 07:22.430 --> 07:22.790 Video. 07:23.060 --> 07:24.770 A great move is played here. 07:24.890 --> 07:26.180 Really fantastic. 07:26.780 --> 07:27.710 400 points. 07:29.600 --> 07:31.400 It's Queen 67. 07:33.900 --> 07:37.470 Now, if Queen takes C one, we can take on D eight with check. 07:37.470 --> 07:39.630 So rook tanks D seven is plate. 07:39.630 --> 07:41.610 And now what's the key check? 07:41.610 --> 07:42.930 We need to use her. 07:44.930 --> 07:48.620 So you either get plus 1000 points or -1000 points. 07:48.650 --> 07:54.920 Get the right check and I hope you find rookie ain't checkers the right check, not rookie check, because 07:54.920 --> 08:01.520 then there is a resource rookie he ain't and won't could resign So rookie check is the way to play this 08:01.520 --> 08:10.790 and then this battery gives this killer common square H and note how the queen hasn't got C1 so this 08:10.790 --> 08:16.310 is winning wrote the answer and now which way to take hair. 08:18.590 --> 08:22.850 The rook again, plus 1000 points or -4000 points. 08:22.850 --> 08:24.590 And currency is important. 08:26.090 --> 08:30.920 We take of the Iraq not to give up the c one square. 08:31.130 --> 08:39.350 If we took the C rock queen, c one check and black has G five to give the accent g six and this is 08:39.350 --> 08:42.380 going to be only a small edge for whites. 08:42.380 --> 08:44.270 So we've rook e tanks to eight. 08:44.300 --> 08:51.020 On the other hand, c one is controlled and black hasn't got a check so can't move the g pawn and black 08:51.020 --> 08:52.850 is in a bad way here. 08:52.850 --> 08:59.570 Black would have to give up the queen because any other move this rook ain't meeting you know this position. 08:59.750 --> 09:02.990 The Queen is actually stopping the king using G five there. 09:02.990 --> 09:03.980 That's embarrassing. 09:03.980 --> 09:07.370 So this this is an embarrassing end of game situation. 09:07.370 --> 09:12.860 So, yes, very interesting how you think it's about the past pawn, but actually it's about king safety 09:12.860 --> 09:15.440 in the back row using the back rank. 09:15.860 --> 09:18.170 So very, very nice tactic. 09:18.170 --> 09:22.400 They're set up quite early on with this move Rook Yuan. 09:22.640 --> 09:26.120 So this choice of you know is about the pawn is about the king. 09:26.120 --> 09:31.010 Quite often it's about the king because, you know, checkmate ends the game. 09:31.700 --> 09:32.410 Okay. 09:32.460 --> 09:35.000 Hope you enjoyed that one and so much.
