WEBVTT 00:01.280 --> 00:07.730 Hi there in this life, shall we say, in my view, a really interesting, instructive game is played 00:07.730 --> 00:10.250 in the British ship of 1999. 00:10.700 --> 00:17.840 Jim Clancy, very dangerous, dynamic tactical player in general against Michael Adams. 00:18.180 --> 00:20.150 So let's see what happened in this game. 00:20.630 --> 00:22.840 For me, it illustrates you've got to be important. 00:22.970 --> 00:27.590 You've got to be very, very careful of your pawns, pawns to not go backwards. 00:29.390 --> 00:36.320 And as such, unlike other pieces, they reflect irreversible decisions in other domains like information 00:36.320 --> 00:43.130 technology, the wrong kind of recommendations to leave the so-called irreversible decisions, the loss, 00:43.130 --> 00:50.690 responsible moments, because you don't want to regret something you can't really reverse without incurring 00:50.690 --> 00:51.650 huge costs. 00:51.980 --> 01:00.200 In fact, in software, you know, architects try and factor those early on to try and get that risk 01:00.200 --> 01:04.130 under control, those ones which are most costly to kind of change. 01:04.130 --> 01:08.540 Later, they try and make the right decisions that it's very, very difficult sometimes to make the 01:08.540 --> 01:12.050 right decisions when there's an irreversibility about it. 01:12.320 --> 01:16.360 One of the big innovations in computers is the undo button. 01:16.730 --> 01:21.650 Where would we be quite often in software without an undo button on the chessboard? 01:21.650 --> 01:25.960 When we move a pawn forward, there's no undo button like the other pieces. 01:26.570 --> 01:27.890 So just bear that in mind. 01:27.890 --> 01:34.660 It's like one of the big lessons that, you know, many, many positional grandmasters like David Noad 01:34.670 --> 01:35.560 is well aware of. 01:35.870 --> 01:41.570 He once went and did a lecture and they're expecting some opening, very dazzling combinations. 01:41.900 --> 01:44.570 And he just emphasized, you know, --'s do not go backwards. 01:45.570 --> 01:49.640 Just bear that in mind in your games, because here, let's have a look at this game now. 01:49.640 --> 01:50.810 Plaskett against animes. 01:50.810 --> 02:02.240 Knight a free of we see these 46 jeoffrey from Plaskett B6 from ASMs determinately some White Castles 02:02.540 --> 02:06.680 C5 C4 Seatmates Queen 64. 02:06.980 --> 02:12.740 So far so good good besame seven Seefried d6. 02:12.770 --> 02:18.320 So Adams is using the kind of hedgehog pwn structure a prickly hedgehog structure. 02:19.250 --> 02:26.870 Roody one a6 we see a fall so it's a kind of boyens structure. 02:26.870 --> 02:32.890 Moxey bind here from white knight beedi seven queeny free queen c7. 02:33.410 --> 02:40.790 Be Frank Adams Castles special be two AC eight right before here. 02:40.790 --> 02:46.790 It seems as though you know Plaskett wants to do something aggressive and dynamic after rook. 02:47.180 --> 02:48.500 He ain't AC1. 02:48.500 --> 02:56.840 It seems his pieces are well placed and would suggest, you know, maybe to start considering some sort 02:56.840 --> 02:58.190 of battering ram against blacks. 02:58.190 --> 03:01.940 Kingside wants to try and win this in a brilliant way. 03:02.180 --> 03:06.110 So Atrius played we see Queen Bee eight. 03:06.110 --> 03:11.090 So Adams just sitting back in this hedgehog's structure, sitting back, waiting a little bit. 03:11.750 --> 03:12.740 We see Rocky one. 03:12.740 --> 03:18.740 And in fact, with this very rookie one has played, Desex is not that vulnerable. 03:18.740 --> 03:20.840 It seems not that exploitable right now at all. 03:21.200 --> 03:27.080 Seems, though, why it's a long way away from exploiting that pawn, which seems to be a potential 03:27.080 --> 03:28.130 theoretical target. 03:28.130 --> 03:32.390 But nothing's like even on defoliate we see. 03:32.990 --> 03:35.600 In fact, now rook see the one? 03:35.600 --> 03:36.620 OK, Bishop Eighty. 03:37.550 --> 03:44.060 But Plaskett is not interested in probing this pawn he's actually interested in affords him some sort 03:44.060 --> 03:50.090 of kingside attack is planned here now. 03:50.300 --> 03:55.040 Otherwise if I were actually giving himself for one moment a backward pawn. 03:56.840 --> 03:58.880 So it's up to pieces to defend these things. 03:59.900 --> 04:00.840 We see offtakes. 04:00.860 --> 04:05.270 If I buy a perk of the back of pawn, it does support the five points further. 04:05.310 --> 04:10.130 Once Pawlenty force now being kind of isolated, there's no follow pawns. 04:11.180 --> 04:15.320 So what's not without structural issues here either? 04:16.070 --> 04:16.880 Look at one. 04:19.070 --> 04:23.210 So does the activity compensate for plainness for her? 04:23.720 --> 04:26.840 On the other hand, you know why it has also weakened some key Diggles. 04:26.840 --> 04:32.210 If the king staying there, this diagonal could potentially be a downside of one's position. 04:32.210 --> 04:39.170 Later, we see Bishop C6 saying basically in terms of peace, harmony, that if this note is given up, 04:39.170 --> 04:43.430 this bishop isn't particularly harmonious, stuck behind its own pawn. 04:43.790 --> 04:47.540 So maybe, you know, blacks bishop isn't really doing much. 04:48.140 --> 04:50.960 And here it kind of threatens B5. 04:51.830 --> 04:57.170 Now, Nîmes, which has an expression, acronyms, which the frat is often stronger than the execution 04:57.830 --> 05:02.870 if you can actually provoke the opponent to play irreversible decisions. 05:04.190 --> 05:08.190 Like -- moves, the opponent may regret those decisions later. 05:09.170 --> 05:16.850 There's weak points which are being created and in fact, with those weak points, as pieces get exchanged 05:16.850 --> 05:20.650 off, those weak points tend to be amplified more and more. 05:21.740 --> 05:26.540 It's like with space, the space opposition. 05:26.540 --> 05:30.050 If you have more space, there's a responsibility to look after the space. 05:32.030 --> 05:33.380 And to become a weakness. 05:35.500 --> 05:40.080 It's like if you had a big, spacious garden, you need to maintain it regularly, otherwise, you know, 05:40.090 --> 05:41.500 it becomes a sort of liability. 05:41.500 --> 05:47.080 The same on the chessboard where space becomes comes responsibility. 05:47.500 --> 05:53.910 There's a comfortable kind of ratio between the number of pieces you have in the amount of space justified. 05:54.700 --> 06:04.060 We see a four so tempting, an irreversible decision and we see that B, free is fundamentally a kind 06:04.060 --> 06:06.570 of backward pawn in one's position. 06:06.580 --> 06:13.690 Now it can only be supported by pieces, so both sides have to circle back the pawns. 06:14.060 --> 06:14.620 In fact, 06:17.830 --> 06:22.030 we see now the bishop dropping back. 06:22.360 --> 06:28.060 So that is not an offer anymore to take out that bishop would have to. 06:28.080 --> 06:33.910 In fact, 1957, although white, it does seem tempting to use this phone. 06:34.720 --> 06:39.310 How effective is this with a big boy sitting on a phone protecting f7 this stumbling drugs? 06:39.370 --> 06:41.410 How effective is that in this situation? 06:42.040 --> 06:50.560 In the meantime, there's a plot for bee free her to be proud royalty AF1 and we see 95. 06:51.250 --> 06:57.910 In fact, there's a specific tactical nuance here of the rook, the one which shows, you know, if 06:57.910 --> 07:04.150 you're not a brilliant tactician as well as a brilliant positional player, then you might not be able 07:04.150 --> 07:09.400 to do anything with the opportunities as they arise. 07:09.610 --> 07:15.430 Now, here there is a golden opportunity to kind of dismantle the entire white position. 07:16.000 --> 07:22.990 I wonder if you can spot it if I give you five cents for the video and it shows actually these kind 07:22.990 --> 07:23.800 of decisions. 07:23.800 --> 07:30.100 You know, the CIFOR and the A4 have given them back support, which is only supported by piece. 07:30.700 --> 07:35.040 So that piece dependancy is a characteristic of a weakness. 07:35.050 --> 07:41.320 If you have candidate weaknesses in the opponents pawn structure, you want to look for where you know 07:41.500 --> 07:43.210 there's greater dependencies. 07:43.420 --> 07:49.980 Sometimes you can knock out those dependencies and really expose underlying those underlying weaknesses. 07:50.440 --> 07:57.600 So here there's a tactical move which really causes why it collapsed in a spectacular manner. 07:59.620 --> 08:02.130 So if I give you five seconds, what would you play in this position? 08:07.150 --> 08:09.160 OK, it's nice to be free. 08:10.810 --> 08:18.550 It's only protected by a piece, but now with that undermine, you know, see for an eye for a weekend. 08:19.210 --> 08:25.870 And the problem with this now of the night after, for it leads to another undermine and undermine leading 08:25.870 --> 08:30.730 to one another on the point that, in fact, hold on a sec. 08:30.730 --> 08:34.120 FBI, too, has taken out its unwitting Sifry. 08:34.480 --> 08:41.750 And wait a second, isn't Sifry a kind of killer common square of the bishop and the rook here? 08:43.210 --> 08:44.050 This is what I mean. 08:44.050 --> 08:52.720 This is like a total collapse of White's position based on one or two extra -- moves, which maybe 08:52.720 --> 08:53.920 shouldn't being played. 08:54.460 --> 08:59.530 All of a sudden, White's position is collapsing, you might think. 08:59.560 --> 08:59.920 Hold on. 08:59.920 --> 09:00.370 Hold on. 09:01.110 --> 09:03.530 Wasn't the FBI holding up F7? 09:03.550 --> 09:04.480 Isn't that an issue? 09:05.500 --> 09:06.670 That's the issue that. 09:09.150 --> 09:14.940 This next wave kind of looked at, but lightning speed, so it's fundamentally, you know, it's going 09:14.940 --> 09:16.300 to win the every night next. 09:16.830 --> 09:19.770 So losing F7 here is not a checkmate or anything. 09:19.770 --> 09:21.210 It's just the queen unsupported. 09:21.780 --> 09:23.150 Now, Siegfried's vulnerable. 09:25.170 --> 09:32.100 So if we take stock here now of the rotates Brooks C7, this played evicting the queen first, not even 09:32.110 --> 09:36.960 rogue taxi for a rogue taxi was actually fine as well. 09:36.960 --> 09:44.280 If we look at this position, three, four, five, one, two, three, four, pawn up lovely bishops, 09:44.280 --> 09:45.350 especially the Dallas Cowboys. 09:47.040 --> 09:50.250 This is just a very, very pleasant possession with Jeoffrey on the fire. 09:53.230 --> 09:53.750 You know what? 09:53.890 --> 09:59.410 What would we be doing here and if there is on the. 10:02.050 --> 10:06.130 So anyway, but this is nifty kicking the queen out first. 10:08.530 --> 10:19.270 We see Queen after an ROTC free her, so it seems how long is it is this really so significant, this 10:19.270 --> 10:19.780 position? 10:22.930 --> 10:26.030 Well, the prettiness of one's position has gone away. 10:26.410 --> 10:28.090 Black is technically a PornHub. 10:28.450 --> 10:30.140 Black does have that Beshir power. 10:30.280 --> 10:33.360 They seem to be so classically placed. 10:33.360 --> 10:38.390 This symbol or rather modernly place these these bishops crisscrossing like this. 10:39.040 --> 10:45.550 But is there a specific issue here causing White to be in big trouble? 10:48.090 --> 10:56.850 Yes, there is that why is under severe pressure in this situation, I think also there's liberation 10:56.850 --> 10:59.430 or opportunities here behind the scenes. 10:59.790 --> 11:02.910 Why plays the tuba as an example? 11:07.210 --> 11:08.110 You know, say. 11:10.260 --> 11:14.780 King to the dance choir, bishop without our counterpoint is a bit of a menace. 11:14.800 --> 11:16.980 You know, what about moves like Bishop E5? 11:17.340 --> 11:23.770 How does then how does Y address Jeoffrey as an issue? 11:23.790 --> 11:25.370 It's very, very tricky. 11:26.070 --> 11:28.650 Yeah, that is one of the big assets here. 11:28.650 --> 11:31.370 In fact, it's not just the act of just having a bishop. 11:31.500 --> 11:37.830 Sometimes it is literally a more specific role that a bishop without a counterpart giving you superiority 11:37.830 --> 11:43.800 on that whole set of colors and dark squares around the board like Jeoffrey are particularly vulnerable 11:43.800 --> 11:46.320 now of this kind of move. 11:46.320 --> 11:51.510 You know, it's very difficult to fans, let alone, you know, opportunities like the five, which 11:51.510 --> 11:53.400 would further battery on Jeoffrey. 11:53.740 --> 11:55.160 Very, very painful stuff. 11:56.340 --> 12:04.560 So we see this move 92 and why it really collapses just in a few moves from here of the work have eight. 12:06.520 --> 12:11.590 Because night before is kind of taken control of the four, in fact, and now Bishop DeFore check. 12:13.850 --> 12:21.710 And all of a sudden, the hold on Bishop DeFore has now got access to a new square. 12:21.740 --> 12:25.310 It's like Chess's a lot about winning access to squares. 12:25.820 --> 12:30.400 Why it's been really hacked in terms of giving up squares. 12:30.410 --> 12:35.720 Why shouldn't have given up squares like, you know, in the field of information security? 12:35.720 --> 12:37.910 That one's given up key squares like every. 12:37.910 --> 12:39.490 Now, where is this queen going? 12:40.040 --> 12:42.830 The queen hasn't got that many squares. 12:43.340 --> 12:47.180 It's really spectacularly gone bad, this position. 12:47.690 --> 12:53.150 The Queen's only got like Jiwon and now the game ends on this next move. 12:54.500 --> 12:58.130 Can you see if I give you five cents for every black player? 12:58.550 --> 13:00.350 Because hang on, you know what? 13:01.220 --> 13:03.260 Isn't the rook hanging as well? 13:05.030 --> 13:06.170 When did this happen? 13:06.170 --> 13:07.820 When when was the rook hanging? 13:08.630 --> 13:13.550 It seems, you know, even I've played through this game several times, but things seem to happen so 13:13.550 --> 13:18.500 quickly in this game after that initial, you know, undermine then draw the line. 13:19.250 --> 13:23.650 The square bishop is just like a monster piece all round the board and all of that. 13:23.660 --> 13:24.890 Why is this rook hanging? 13:25.460 --> 13:28.570 The thing is, you know, if Bishop takes fine, OK, there's queen free. 13:28.640 --> 13:29.660 But when did this happen? 13:29.690 --> 13:30.550 Let's rewind. 13:30.830 --> 13:33.770 When when on earth did this happen? 13:37.460 --> 13:41.240 The rook was x raying, was being x rayed by the bishop here. 13:42.860 --> 13:49.670 So so happens around here that actually this is a double tag unleashing that attack on the rogue and 13:49.670 --> 13:50.180 the queen. 13:50.540 --> 13:51.650 It was a double attack. 13:52.790 --> 13:54.260 And this is a desperate defense. 13:54.260 --> 13:56.900 But now Adams just plays Rook Differe shutting down. 13:58.820 --> 14:00.320 You know, Queen takes a look at the end. 14:00.320 --> 14:02.480 So we're just leaving this double attack. 14:05.340 --> 14:06.240 Devastating. 14:09.050 --> 14:14.000 This is why for me, you know, if you want to study -- structures in human chess, you look at atoms 14:14.000 --> 14:21.680 and, you know, certain grandmasters, you know, like Eric Hanson have also expressed, you know, 14:21.680 --> 14:24.410 that they've studied Michael Adams. 14:24.800 --> 14:26.720 He's a fantastic structuralist. 14:27.800 --> 14:30.830 We can study the world champions in the unofficial world champions. 14:30.830 --> 14:37.730 But if we want to learn about Paul structure, you go to a specialist, maybe a specialist in the U.K. 14:37.730 --> 14:42.860 Is Michael Adams a specialist as a structuralist in the US is yassa. 14:42.870 --> 14:46.640 So when they just love Puhn structures. 14:48.110 --> 14:55.280 They literally called structuralists Bahir, you know, it's like such a rapid tactical disaster, it's 14:55.280 --> 14:58.640 difficult to take this all in in one go. 14:58.790 --> 15:02.980 What on earth has been happening here after night takes be free. 15:02.990 --> 15:06.170 We really need to, like, take this in slow motion. 15:06.170 --> 15:16.610 Some irreversible decisions lead to, you know, a set of undermines which take how essentially a dance 15:16.620 --> 15:22.400 choir bishop, which in itself so there's one undermine after another on the way, which leads to a 15:22.400 --> 15:29.110 kind of further undermine of of why on the dark squares, it's complete obliteration. 15:29.810 --> 15:34.070 It's like free controlled explosions, one after the other. 15:34.070 --> 15:36.320 So quickly this happens. 15:36.650 --> 15:39.320 You don't know what on earth hit white. 15:40.970 --> 15:47.510 So taking out CIFOR, taking out B to all of a sudden all the squares around the board and the rock 15:47.510 --> 15:50.210 is a liability in this in this position. 15:50.510 --> 15:57.860 It's not just, Jeoffrey, it's very difficult to estimate the damage potential of this position in 15:57.860 --> 15:59.630 terms of the stance Squarepusher. 16:00.020 --> 16:06.140 And certainly I've looked at this game several times and there's always a new insight. 16:06.170 --> 16:07.880 This is the funny thing about chess. 16:08.210 --> 16:14.570 As you improve, you can revisit old games and find new finesses that you didn't it didn't really occur 16:14.570 --> 16:14.990 to you. 16:15.500 --> 16:18.470 But, you know, these games are played on the one day time control. 16:18.470 --> 16:19.100 So why not? 16:19.100 --> 16:25.460 They had you know, they spent hours on their moves that we just spectators, tourists, casual tourists. 16:25.460 --> 16:27.170 So maybe that's to be expected. 16:27.470 --> 16:31.040 You revisit these games, you get these new you insights. 16:31.040 --> 16:35.480 But here, it's like essentially free undermines wins in a row have been played. 16:35.960 --> 16:40.250 And why is fatally weak on the dark squares here, even after rooked seefried? 16:40.250 --> 16:43.280 Because the dark square bishop has been taken out. 16:44.480 --> 16:49.280 So yeah, Wykes position has totally been uprooted and exposed on the dark squares in particular. 16:49.280 --> 16:51.650 This bishop isn't so lethal as this one. 16:51.650 --> 16:55.430 I would say that this is the more lethal bishop in the short term here. 16:57.620 --> 17:07.400 But it's so lethal, you know, the this I mean, it looks like a very problematic position here, just 17:07.400 --> 17:11.840 with things like Bishop E5 on the cards, let alone other things. 17:12.500 --> 17:18.440 But, yeah, this exposure of, you know, the unprotected piece on B to the dark sky, it's all coming 17:18.440 --> 17:25.640 together here with the forcing moves, underlining all of these dance great liabilities now, especially 17:25.640 --> 17:31.610 the rock on BE2, just hanging on to a truly crushing game and mysterious to this day. 17:31.610 --> 17:36.650 I have to say, you can look at this game over and over again and pick up more and more finesses. 17:37.100 --> 17:41.300 But this kind of game does echo this idea, the small central idea. 17:41.750 --> 17:44.010 You've got to be careful of your pawn moves. 17:44.030 --> 17:47.090 They are the irreversible decisions on the chessboard. 17:47.390 --> 17:54.470 And that's why, as an annotator certain annotators, I like you know, when I'm looking at games, 17:55.190 --> 17:58.810 when a pawn movies might say, well, why was Paul needed? 17:58.820 --> 18:00.470 Was it really, really justified? 18:00.890 --> 18:04.880 Because they are the irreversible decisions on chess board. 18:05.600 --> 18:08.610 And so when you're playing a game, you should be careful with your moves. 18:08.780 --> 18:09.320 OK. 18:10.460 --> 18:11.060 There's so much.
