WEBVTT 00:01.470 --> 00:02.050 Hi there. 00:02.580 --> 00:08.430 In this example of meeting with the two bishops against King, how would we do this? 00:09.060 --> 00:10.800 This is a bit trickier, is it? 00:11.160 --> 00:18.750 But we want to shrink the kind of rectangle that the king lives in and we can do this by indisposition. 00:18.750 --> 00:27.180 Bishop G5 So we're starting to build a wall against the king now, say King eight, as if the king's 00:27.180 --> 00:30.590 going to escape onto the side of the boat. 00:30.600 --> 00:34.100 But we want to make them over here either on HIV or AIDS. 00:35.250 --> 00:36.540 We can play Bishop R5. 00:36.540 --> 00:40.140 We've created a wall, a virtual wall with the bishop path. 00:41.310 --> 00:46.920 And basically we've shrinks the rectangle that the opponents can can live in. 00:48.030 --> 00:50.890 The rectangle is now potentially this rectangle. 00:53.010 --> 00:59.670 So here with the bishops in place, crane, that wall, the king's not really escaping outside of that 00:59.670 --> 01:00.450 rectangle. 01:01.560 --> 01:02.970 That's to shrink that rectangle. 01:03.120 --> 01:04.980 We're going to bring the king up the boards. 01:04.980 --> 01:15.270 King be to give him seven king Seefried King Jesus, King DeFore, Camp seven say waiting around Kingi 01:15.270 --> 01:17.850 five, King seven, now kinky sex. 01:18.570 --> 01:25.200 So now we're starting to restrict the opponent's rectangle to only these squares. 01:25.800 --> 01:26.610 Pretty limited. 01:27.630 --> 01:32.250 Can't wait for me in the square as well. 01:34.580 --> 01:43.180 But of the king of things, King ain't that he is going to be taken away now, soon after King desex 01:43.190 --> 01:45.660 first key waiting move King. 01:45.920 --> 01:54.670 And now we're going to really make the Kings rectangle just these two squares with this next move. 01:55.550 --> 01:56.300 Can you guess? 01:58.610 --> 01:59.330 Work it out. 01:59.510 --> 02:04.790 Well, ideally, we can play Bishop D7, so the king only lives in two squares. 02:04.820 --> 02:06.130 Now we're nearly there. 02:06.770 --> 02:07.640 Kingsgate 02:10.700 --> 02:16.610 Bishop ASX stopping the King and Efate King at eight. 02:16.610 --> 02:18.680 And in fact, we don't even have the checkmate. 02:18.680 --> 02:21.410 The King on the corner here. 02:21.800 --> 02:27.580 The most efficient thing to do is Bishop 87 Check and Bishop six Samit. 02:30.090 --> 02:36.330 So, yeah, the shrinking rectangle principle also applies when you have the bishop that we want to 02:36.330 --> 02:41.010 kind of make sure that the opinions king is in a shrinking rectangle. 02:41.010 --> 02:46.500 We have to create a wall, a virtual wall around the king so it doesn't escape. 02:46.830 --> 02:57.780 So the virtual wall gives us time to bring our king up to assist and shrink where the king lives. 02:58.410 --> 03:03.690 So the king currently lived on these squares. 03:04.320 --> 03:10.290 That was the the kind of freedom of the king, the king's kind of prison. 03:11.040 --> 03:13.890 And we kind of shrink it by bringing the king up the board. 03:15.600 --> 03:21.160 And then the Kings in a really aggressive place can't escape requires quite a lot. 03:23.250 --> 03:30.330 So actually, by by the acts of king, if in fact, if we look at this, the king one one on forsakes 03:30.330 --> 03:33.090 now, you know, the king's being restricted find. 03:35.270 --> 03:43.460 To these squares, and I'm we're taking out the eight square here, so the Kings now confined just to 03:43.460 --> 03:44.570 these free squares. 03:46.100 --> 03:52.930 So, yes, and now the king's only confined to two squares and now it's the chapel. 03:53.630 --> 04:02.490 So, yes, there is a beauty to behold in these simplified positions how these pieces work together. 04:03.650 --> 04:07.770 So the bishops are working together to deliver that checkmate. 04:08.300 --> 04:13.730 I hope you enjoyed that and got some principles and a little bit more reassurance that you can actually 04:13.910 --> 04:18.930 meet with the bishop here, but you might want to practice with a friend or chess computer. 04:19.940 --> 04:21.680 OK, that's about.
