WEBVTT 00:01.530 --> 00:02.110 Hi there. 00:02.730 --> 00:11.100 In this election, we're going to talk about fan strengths, so these are full SCIAF and words notation. 00:11.610 --> 00:21.900 So it's attributed to David Forsayth, who was between 1854 and 1939, was a Scotsman who emigrated 00:21.900 --> 00:26.300 to New Zealand, served as a chess editor of the Glasgow Weekly Herald. 00:27.060 --> 00:32.040 So Forsyth invented foresighted notation as a method of recording transpositions. 00:32.640 --> 00:43.590 And later it was extended by someone called Stephen James Edwards, who was between nineteen fifty seven 00:43.590 --> 00:44.520 to twenty sixteen. 00:44.520 --> 00:49.610 So later, Stephen, James Edwards applied to extend the net. 00:50.160 --> 00:56.630 So it was more sophisticated and could really record things like the plan to move the casting available 00:56.790 --> 00:57.470 and other stuff. 00:58.290 --> 01:01.050 So we're going to have a look at Forsyth Edward notation. 01:01.290 --> 01:02.660 AdWords notation. 01:03.060 --> 01:04.580 It's quite easy to slip up. 01:05.730 --> 01:11.460 So fen strings for SCIAF Edwards notation for being technically correct. 01:11.490 --> 01:13.520 Steve, Steven, James Edwards. 01:13.920 --> 01:18.700 So here is a string at the start of the game is going from top left to bottom right. 01:20.430 --> 01:21.840 Here's the first filled. 01:22.770 --> 01:26.910 The second, the third, the fourth, the fifth or sixth. 01:26.910 --> 01:27.990 There were six Feld's. 01:29.970 --> 01:30.390 Yeah. 01:30.810 --> 01:38.670 So the piece placements you have the pieces in the standard algebraic notation or some notation for 01:38.670 --> 01:39.090 short. 01:39.600 --> 01:48.040 So a small R is a black rook, a small and as a as a black knight capital N is a white knight. 01:48.330 --> 01:54.420 So we got all the black pieces, we got the small pieces were small, you know, the black --'s and 01:54.420 --> 01:57.420 then at each end of row you put a forward slash. 01:57.420 --> 01:59.930 So forward leaning slash or just short. 02:00.480 --> 02:02.100 So that's the standard slash. 02:02.520 --> 02:05.130 And then we have the next row. 02:05.500 --> 02:06.990 Then we come to the end of the row. 02:07.980 --> 02:10.500 If there's spaces, you just count the number of spaces. 02:10.500 --> 02:13.670 So there's eight spaces there, eight, eight, eight. 02:13.680 --> 02:15.300 You can see that emerging. 02:15.690 --> 02:17.610 Then the --'s the white --. 02:17.920 --> 02:20.160 So if we move a pawn here, look what happens. 02:22.170 --> 02:24.030 We get a one emerge here. 02:24.030 --> 02:24.840 Look at this row. 02:25.380 --> 02:26.520 There's four pawns. 02:26.520 --> 02:27.510 One, two, three, four. 02:27.690 --> 02:30.090 Then there's a one and then three pawns. 02:30.570 --> 02:32.990 Also, look what happens here to this felt. 02:33.960 --> 02:36.810 So this is the Ampersands Felde. 02:38.480 --> 02:44.450 This word from Lancefield is the Thompson Target Square, and it's recorded, even though there's no 02:44.450 --> 02:48.680 -- on DeFore Refought, still recorded, you still record it technically. 02:48.730 --> 02:54.500 So, Avery, so let's say let's get the going. 02:55.220 --> 02:57.400 So say see five inflectional. 02:57.410 --> 02:58.850 Is that is that a good move? 02:59.810 --> 03:03.740 If we're going to record the free as some songs square out, we'll have to play defore. 03:04.610 --> 03:11.930 So now differe is recorded and because there's a -- on Frank Black, Lacy takes frame. 03:13.610 --> 03:19.490 And if you're writing this on scoresheet you can optionally put it doesn't you don't have to put. 03:20.560 --> 03:26.750 Hadopi, not to signify I'm sorry, just just make it even clearer than it was longsword. 03:27.610 --> 03:32.320 So anyway, so we've got the felt that we've also got castling availability. 03:34.450 --> 03:38.290 Now this shows a capital K capital KWEM. 03:38.710 --> 03:39.670 Q means we can. 03:39.670 --> 03:41.580 Kosslyn Both the Kings Island Queen site. 03:41.950 --> 03:45.880 Now, let's say we forfeited all rights council on the Queen side. 03:45.880 --> 03:46.270 Right. 03:47.530 --> 03:48.640 Let's see what happens. 03:48.670 --> 03:49.860 Thank you. 03:49.960 --> 03:50.650 Thank you. 03:51.370 --> 03:53.550 So say, you know, I just a. 03:54.130 --> 03:58.060 I move the rook and I quickly, you know, move it back. 03:58.450 --> 04:01.090 So let's give that back. 04:01.840 --> 04:09.280 Even though it's not visually apparent now that we can you know, if you just gave that first part of 04:09.320 --> 04:14.310 the string, how do we know if we can call the queen side or not? 04:15.130 --> 04:18.580 But this Felde shows us that we can only cancel Kingside. 04:18.580 --> 04:20.170 It's only a capital K there. 04:20.680 --> 04:23.950 We can only cancel Kingside so the software knows. 04:24.910 --> 04:32.350 So for example, here, you know, they can cancel and then we're left with a K there and we can't do 04:32.350 --> 04:32.540 this. 04:32.680 --> 04:37.000 It's an illegal move, but we can't go and cancel Kingside. 04:37.690 --> 04:40.490 And then once no Psychon calls, it becomes a dash. 04:41.140 --> 04:46.630 So these six fildes are kept intact by their spaces, you know, space, space. 04:46.780 --> 04:49.500 And when they're irrelevant, you know, they've become a dash. 04:50.830 --> 04:53.050 So the second filled the active color. 04:53.060 --> 04:56.230 In case you haven't already picked that up so small. 04:56.350 --> 05:01.690 We mean as whites move small, B means black to move the active color to move. 05:01.870 --> 05:02.980 So we move. 05:03.010 --> 05:06.100 It goes to B and then it switches to W. 05:06.370 --> 05:07.390 So that's fair enough. 05:07.390 --> 05:08.320 The active color. 05:10.800 --> 05:16.650 So, yeah, then we got, you know, the costing over Birthe Johnson's Hoggett Square, the half moon 05:16.650 --> 05:21.190 clock is the number of moves since the last pawn move or capture. 05:21.540 --> 05:26.420 So that's good for knowing if the 50 move drawer rule has been activated or not. 05:26.820 --> 05:32.020 So the 55 drawer rule, that's like 100 ply since the last poll move or capture. 05:32.040 --> 05:33.510 So this will keep going up. 05:34.540 --> 05:41.980 As long as there's no poor move or capture, as soon as we play a poor move, that 13 is going to go 05:41.980 --> 05:42.760 to zero. 05:42.900 --> 05:44.620 Look, because there's been a poor move. 05:45.250 --> 05:48.430 So the 15 overall starts counting up again. 05:49.150 --> 05:50.710 So you can tell this from that fence. 05:51.250 --> 05:51.550 I know. 05:51.550 --> 05:52.360 It's really clever stuff. 05:52.360 --> 05:53.980 Is that the full move? 05:54.010 --> 06:00.670 No, it's like move 14 now, even though we haven't recorded 14, it is move 14. 06:00.670 --> 06:07.490 As soon as we going to move its move, 14 dots, Brooke, 81 disambiguate, 51 one. 06:08.670 --> 06:14.260 Remember those disambiguation in concise notation, algebraic notation. 06:14.650 --> 06:18.490 So, yeah, with these six Feld's this is the Fantana, the six Feld's. 06:18.730 --> 06:27.850 So credit to these two amazing people, David for SCIAF and and later Steven James Edwards. 06:28.360 --> 06:35.170 So we say capital F Capital E Capital and denoting Foresi Edwards notation. 06:35.360 --> 06:41.910 So in practice you can grab this fancy ring and you can control it sometimes in other software and it 06:41.920 --> 06:46.810 pairs with the right side to move cost available, homesite, etc.. 06:46.810 --> 06:51.600 You got all six feld's, which are absolutely necessary and important. 06:51.610 --> 06:53.230 So it's not just where the pieces are. 06:53.230 --> 07:00.760 You want to know the other stuff as well, especially the turn to move tons, which is really powerful 07:00.760 --> 07:04.060 interests of decides the fate of who wins the game. 07:04.060 --> 07:07.540 If you know, if you if you have a move often, that's really quite good. 07:08.020 --> 07:15.370 So anyway, Forsayth Edwin notation, I hope that's a little bit clearer what it is based on two great 07:15.370 --> 07:23.560 guys that contributed to help us share both games, games, scores and positions. 07:25.320 --> 07:31.710 Especially Steven James Edwards, who was also involved in the planned portable game notation standards, 07:32.190 --> 07:40.110 which very slightly, by the way, from standard algebraic notation, which is what Veli uses. 07:40.110 --> 07:42.820 So portable game notation has some slight differences. 07:43.500 --> 07:46.780 So if you want to nerd up on that and check that out. 07:49.410 --> 07:53.180 OK, so anyway, so I hope that's clear. 07:53.220 --> 08:00.000 It's a way of representing transpositions, full strength, as I like to call them, fense. 08:01.420 --> 08:03.130 OK, that's so much.
