WEBVTT 00:00.960 --> 00:01.680 Hi there. 00:02.280 --> 00:09.360 In this lecture, there is an amazing discovery attack, which you can make use of, can you work out 00:09.360 --> 00:10.380 why it's good? 00:10.950 --> 00:12.140 So white playing? 00:12.150 --> 00:16.010 If I give you five seconds to pause the video, what would you play in this position? 00:20.370 --> 00:27.060 OK, so Bobby Fischer against Boris Spassky, Game eight, saw this kind of blunder move the seven, 00:27.870 --> 00:31.770 which did invite a kind of weakness of the last movement, the the DFI Square. 00:32.100 --> 00:39.850 And in fact, Bobby Fischer capitalizes on this amazingly boy discovered attack style move 95. 00:39.870 --> 00:46.890 So not only we follow the arrows of the night and this one, you don't want to be just distracted with 00:46.890 --> 00:51.450 that look all around the board at the discovery effects on the entire position. 00:51.900 --> 00:58.290 Angasi, the rook has been liberated and also the queen has been liberated in this direction as well, 00:58.290 --> 01:00.630 hitting the opponents queen. 01:00.990 --> 01:05.070 So it's not just the threat of the knight taking the pawn, which would be Chac. 01:05.640 --> 01:12.060 So these are discovered effects on the entire board actually mean why it's actually increasing the advantage 01:12.060 --> 01:12.380 here. 01:13.140 --> 01:18.390 So Boris Spassky cannot, for example, move his queen back because, you know, Brooke takes C4. 01:19.050 --> 01:19.910 Thanks very much. 01:19.920 --> 01:21.600 Place to be taken there. 01:22.080 --> 01:23.310 So Queen takes two. 01:23.310 --> 01:25.770 Black is severely, severely limited in reply. 01:25.770 --> 01:28.260 So Queen takes the two now here. 01:28.260 --> 01:29.970 What do we play in this position? 01:32.130 --> 01:32.790 OK. 01:35.400 --> 01:42.990 We play actually in 1987 check, this takes out an important Santa pawn and the king of eight. 01:45.610 --> 01:54.010 We simply in this position, can you spot out what we simply playing, OK, we play actually Rook takes 01:54.220 --> 02:00.640 two knowing that even if they take all night, we have that discovery attack on Bishop still to exploit. 02:01.630 --> 02:04.290 So this is much better than anything else. 02:04.450 --> 02:11.730 You know, if we played 1966, it's not the time or the place for a desperado, a tactical, you know, 02:11.860 --> 02:15.010 a desperado tactic, which is not a tactical idea. 02:15.160 --> 02:20.950 It's not the time and place for that, because here it's not so much material advantage. 02:20.950 --> 02:22.990 We never get time to capture that bishop. 02:23.860 --> 02:25.900 We only capture, you know, the queen. 02:25.900 --> 02:31.960 So we just leave the night in place there and just simply recapture the queen, allowing the night to 02:31.960 --> 02:32.500 be taken. 02:32.500 --> 02:35.230 But this does allow us now to play Rook take CIFOR. 02:35.740 --> 02:41.830 So Fisher has increased his advantage from this little tactic and went on to win from this position 02:42.190 --> 02:43.150 fairly comfortably. 02:43.630 --> 02:50.920 So if we look at the discovery attack mechanism here, there are actually two main liberation's. 02:51.550 --> 02:54.160 If we look at the number of liberationists, not just one is one. 02:55.240 --> 02:59.470 The queen is liberated to attack the queen and the second one is here. 02:59.830 --> 03:06.790 So it's not just the frat's employed by the Knight Move in itself, but rather the effects on the entire 03:06.790 --> 03:07.360 position. 03:08.950 --> 03:09.770 So that should be there. 03:10.120 --> 03:13.370 So the effects on the entire position need to be factored in. 03:14.110 --> 03:21.280 So look for those discoveries, don't just be kind of distracted by the last move and what employees 03:21.280 --> 03:26.860 you want to look at, the implications on the entire position, what pieces have been liberated, the 03:26.860 --> 03:29.000 discovery effects on the entire position. 03:29.710 --> 03:30.150 OK. 03:30.200 --> 03:31.390 Have you found 95? 03:31.420 --> 03:34.870 It's a pretty crushing move and it increases White's advantage. 03:35.560 --> 03:36.130 All right. 03:36.470 --> 03:37.120 Thanks so much.
