WEBVTT 00:01.220 --> 00:08.400 Hi there in this line, shall we say that the arm Checkmate is kind of separate the calculation. 00:09.530 --> 00:17.150 Sometimes you have the opponents, Kingscote Squares all cut out, but here they're all Cartwell. 00:18.410 --> 00:20.220 The king has no escape squares. 00:20.240 --> 00:22.850 The king cannot move anywhere. 00:22.850 --> 00:24.320 But you know what? 00:24.320 --> 00:29.250 We need to introduce that krsek to actually make this mean, you know, checkmate. 00:31.190 --> 00:32.990 Where does this Krsek come from? 00:34.130 --> 00:35.060 On this occasion. 00:38.810 --> 00:40.190 This is a bit of a quandary. 00:40.220 --> 00:42.320 It's like a catch 22. 00:44.590 --> 00:50.710 Because, you know, if we move the rook, then this is not threatening checkmate, we're not threatening 00:50.710 --> 00:51.640 checkmate anymore. 00:52.010 --> 00:52.990 We've got G-7. 00:53.110 --> 00:54.040 It's not even a threat. 00:55.060 --> 01:00.490 The rook is controlling escape squares and they all seem to be tied up, you know, controlling escape 01:00.520 --> 01:01.020 squares. 01:01.630 --> 01:08.560 Is there any free resource here that we can add to the equation which might be useful for delivering 01:08.560 --> 01:13.630 an actual checkmate while the other pieces here are struggling to keep the king contained? 01:14.380 --> 01:15.820 What's the checkmating? 01:18.250 --> 01:20.770 Piece or. 01:22.020 --> 01:22.710 Paul. 01:25.410 --> 01:26.860 That's a bit of a clue for you. 01:27.180 --> 01:28.740 Sometimes you can actually check my make. 01:30.000 --> 01:38.300 Now, these pawns, they seem unlikely candidates which are made the opponents came totally true. 01:38.760 --> 01:40.050 This point seems unlikely. 01:40.050 --> 01:40.560 Can they? 01:42.240 --> 01:43.070 What about this guy? 01:44.820 --> 01:47.610 You know, in theory, there's a theoretical downside. 01:47.620 --> 01:48.960 This is super theoretical. 01:49.440 --> 01:54.060 But if this poll came up, the border would actually be the only pawn to deliver a check. 01:54.840 --> 01:55.610 Look at these others. 01:55.620 --> 02:01.110 They don't deliver a check that doesn't deliver a check that the check is the only pawn which will actually 02:01.110 --> 02:02.100 deliver a check here. 02:02.310 --> 02:03.780 This one can't deliver a check. 02:05.750 --> 02:08.600 We're talking sometimes we have to step back totally fair at school. 02:08.960 --> 02:14.630 That's almost a fact of the case to celebrate is that we want to celebrate all facts of the case. 02:15.290 --> 02:19.490 We might not be using loud sounding, forcing me to celebrate our facts of the case. 02:21.080 --> 02:26.300 We might sometimes be using quiet moves, especially when we already have a kind of meeting that sets 02:26.300 --> 02:34.580 up taking the arrows off, which is a fantastic move in this position, which can actually help deliver. 02:35.710 --> 02:36.370 Cellmate. 02:38.360 --> 02:44.480 Yeah, the are checkmates sometimes dictates you need to introduce a new piece or -- to chat where. 02:44.540 --> 02:46.350 And here we can do that with A4. 02:47.180 --> 02:48.380 This is a wonderful move. 02:48.860 --> 02:53.690 If we look at our processes of calculation now, you know, black actually has to resign. 02:53.690 --> 02:59.720 If he thinks that's a weakness of the last move, it's weakened can full control, which means we've 02:59.720 --> 03:03.080 got a new opportunity right before it's checkmate. 03:06.800 --> 03:07.420 Ouch. 03:09.840 --> 03:15.430 And the thing is, OK, so they challenge one of our pieces, what do we have here? 03:16.020 --> 03:19.170 Check the little bits, the forcing those all checks. 03:24.460 --> 03:30.370 Every check will check there and there's quite a few checks to consider like these six, but doesn't 03:30.370 --> 03:33.100 do anything, surely rookie something that doesn't do anything, surely. 03:34.960 --> 03:38.200 But what about the other checks, even the outrageous ones? 03:38.660 --> 03:41.480 What about our theoretical fact that we established about this --? 03:41.800 --> 03:50.410 Hopefully we can arrive at 94 check to celebrate some more theoretical fact that we observed that now 03:50.440 --> 03:55.300 on 884, yeah, we can deliver the final checkmate with that five. 03:58.050 --> 04:04.410 The key point of this example is, yeah, taking out escape squads in the arch at night, but sometimes 04:04.410 --> 04:11.310 you do need to introduce a lot of people to do the final check and sometimes you need to check out theoretically 04:11.310 --> 04:18.390 to establish almost that theoretical fact, a fictional fact and fiction that certain people could, 04:18.390 --> 04:20.970 in theory, check the opponent's king. 04:21.150 --> 04:26.030 That could be the difference between you losing and winning a game of chess. 04:26.670 --> 04:30.600 So try and ascertain these theoretical facts of these theoretical checks. 04:31.080 --> 04:37.110 They could be the ingredient you need to add to your meeting that to make it about me, because those 04:37.110 --> 04:42.600 existing pieces that they're too concerned with controlling the skyscrapers, you need another check 04:42.600 --> 04:45.460 from somewhere and sometimes it can be a little pawn. 04:46.350 --> 04:48.780 OK, so I thought this is a bit of a beautiful example. 04:49.500 --> 04:50.400 I hope you like it. 04:50.700 --> 04:54.510 And I hope that idea of the art of checkmate is a separate art in its own right. 04:55.440 --> 05:01.050 The art of taking out game squares and introducing sometimes checks from unexpected sources, even --'s. 05:01.970 --> 05:03.740 OK, that's much.
