WEBVTT 00:01.440 --> 00:02.260 Hi there. 00:03.270 --> 00:10.530 This is a very difficult position for black indeed, Mammadyarov is playing whites against Margaret 00:10.530 --> 00:10.950 Carlson. 00:10.980 --> 00:18.390 This isn't the 2007 World Championship, even in Blechacz and in bullet chess, Magnus's tactical ability 00:18.390 --> 00:19.140 is amazing. 00:19.140 --> 00:25.380 It's immense is a tentacle monster and he's able to use X-Rite tactics just like that. 00:26.010 --> 00:32.280 We see here that there's a theoretical connection of the rook here through these other squares, through 00:32.280 --> 00:33.150 this D7. 00:33.750 --> 00:40.170 If the rook has x ray vision and Magnus's pieces generally do have X-ray vision, then it's kind of 00:40.170 --> 00:42.750 looking through these squares at least. 00:42.750 --> 00:45.710 And even this one, it kind of looks through potentially. 00:46.410 --> 00:49.130 So imagine that Rook has X-ray vision. 00:49.500 --> 00:51.510 Is there a great resource here for black? 00:51.630 --> 00:57.390 It doesn't win on this occasion, by the way, but it does help black significantly to fight on and 00:57.390 --> 00:59.890 eventually to win. 00:59.910 --> 01:04.590 So what is the move here that you might consider for black in this position? 01:05.930 --> 01:10.230 I give you five cents for the video, so I'm giving you a bit of a clue. 01:11.120 --> 01:16.710 Does this rock have some superpowers to make use of or do we just move out of the way or take on these 01:16.710 --> 01:17.150 seven? 01:22.080 --> 01:26.550 OK, a great movie is played in the circumstance, Bishop DeFore Jack. 01:28.020 --> 01:39.240 Yeah, and the point is revealed that on rotates we have now 92 check and 1964 and I rook's ready to 01:39.240 --> 01:46.710 take on the fall of 1984 in the event, by the way, the game was a struggle and carried on for quite 01:46.710 --> 01:48.540 a bit as the afterwork takes the eight. 01:48.540 --> 01:52.450 Eventually Magnis won this possession, but it is very, very tricky. 01:53.850 --> 01:58.510 But anyway, the key point is look out for your x rays. 01:58.530 --> 01:59.850 Be resourceful with them. 02:01.060 --> 02:06.570 If the opponents had played Brooks 64, that's more straightforward. 02:06.930 --> 02:13.590 We can take care and if taken only to check, it's more straightforward and it's still a tricky possession 02:13.590 --> 02:13.890 after. 02:13.900 --> 02:21.810 But the essential part of the X-ray is revealed here with Bishop Leaford, Jack Black cheekily using 02:21.810 --> 02:27.290 that square, which is being kind of x rayed from the rook on the eight. 02:27.570 --> 02:33.780 So very, very important tactical idea to be aware of the X-ray capabilities of your pieces and how 02:33.780 --> 02:37.040 they support certain tactical operations. 02:37.710 --> 02:40.050 OK, I'll show you the game. 02:40.470 --> 02:43.340 How did Bengals actually play from this position? 02:43.350 --> 02:44.490 Here's the exchange up. 02:45.480 --> 02:46.290 But you know what? 02:46.290 --> 02:48.120 Why it has dangerous passports. 02:48.120 --> 02:49.590 It's only a game, though. 02:49.890 --> 02:53.550 He tries to stop them resourcefully, gets behind them. 02:53.550 --> 02:54.840 This is the Tarasco. 02:55.110 --> 03:02.280 When you get behind the opponents passports, key defensive kind of generalization made by Haroche, 03:02.520 --> 03:07.140 you should get Rook's behind passports, either your own or the opponents. 03:08.340 --> 03:13.410 And so he stepped up that pawn and that makes it less scary. 03:13.770 --> 03:20.490 So now he was the exchange up and then he simplified that simplification. 03:20.490 --> 03:26.610 When you up simplifies the position like simplifying a mathematical equation, making it clearer easier 03:26.610 --> 03:27.550 to win quite often. 03:27.930 --> 03:32.700 That's why you simplify it quite often when you're up, generally when you're up, you want to simplify. 03:32.970 --> 03:36.690 When you're down, you want to keep the position more complicated, complicated. 03:36.690 --> 03:37.440 It's complex. 03:38.010 --> 03:42.600 So here Magnus is making inroads with his king and it's an enormous end. 03:42.600 --> 03:43.790 Game Ten is revealed. 03:43.800 --> 03:44.970 This is a cheeky move. 03:44.970 --> 03:46.560 If takes, then King takes. 03:47.370 --> 03:50.700 So the pawns are now fixed, fixed target pawns. 03:51.360 --> 03:58.110 And here, after King E five waits in big trouble, the king's having to make way for the black king. 03:58.110 --> 04:02.760 So White resigned her, for example, hair care for it looks as though these pawns are going to be wiped 04:02.760 --> 04:04.260 out pretty soon. 04:04.260 --> 04:05.160 For example, here. 04:05.700 --> 04:06.540 And then we can start. 04:06.630 --> 04:08.640 We can just take out the pawns. 04:09.060 --> 04:16.560 So anyway, but the key tactic which set the ball rolling earlier on in this key moment using the x 04:16.560 --> 04:16.860 ray. 04:17.490 --> 04:24.870 So let your pieces use their X-ray vision, see what possibilities they actually indirectly support 04:25.290 --> 04:26.610 with their x ray visions. 04:27.330 --> 04:29.280 OK, Pennsy much.
