WEBVTT 00:01.910 --> 00:11.600 Hi there in this lecture, I'd like to qualify the act of capturing or recapturing in general quantifying, 00:12.020 --> 00:19.130 quantifying that idea that if you're winning overall already or losing overall here, we're actually 00:19.130 --> 00:20.020 a pawn down. 00:20.420 --> 00:27.470 And in general, when you're material, don't you want to exchange --'s not pieces? 00:29.460 --> 00:34.120 Also, we are a pawn down on this seafoam. 00:34.190 --> 00:35.560 We have a missing pawn. 00:36.230 --> 00:43.430 That's an interesting observation as well, that we have potentially a same open file, what's called 00:43.430 --> 00:43.790 a time out. 00:43.790 --> 00:47.180 And far as I go, a one way road in chess. 00:48.560 --> 00:50.990 In general, we don't want to exchange pieces. 00:51.200 --> 00:52.580 So here. 00:54.900 --> 01:00.840 If I gave you the choice, the first of all of King F7, I'm looking at let's discuss King F7 versus 01:01.020 --> 01:06.780 the eight, what would you think is a slightly better move out of those two? 01:10.350 --> 01:13.650 OK, if I give you five cents, think about that. 01:16.540 --> 01:22.330 OK, it will be actually on this occasion, in this particular position, Camp seven, we're not exchanging 01:22.330 --> 01:24.280 pieces, we're keeping the tension. 01:24.940 --> 01:28.000 So out of those two, king of seven is a better bet. 01:28.270 --> 01:33.520 When you exchange pieces, it's like you're simplifying a mathematical formula and you're making it 01:33.520 --> 01:35.290 easier for the opponent to win eventually. 01:35.980 --> 01:42.190 In fact, there is a better way of exchanging things if you do want to exchange things, is to exchange 01:42.190 --> 01:48.280 --'s, because sometimes it's difficult when the opponent doesn't have, you know, too many pawns 01:48.280 --> 01:49.030 in an end game. 01:49.030 --> 01:58.510 If they can't win that easily, it might end up more in general as a draw statistical probability of 01:58.510 --> 01:59.860 drawing increases. 02:00.220 --> 02:03.400 If you try and exchange pawns, not pieces. 02:03.760 --> 02:09.400 It so happens in this particular position that especially because we've got this segment forward play 02:09.400 --> 02:16.480 where we can actually play a clever move here, a fine of changing the opponent's pawns if they take 02:18.430 --> 02:20.650 it's like we've just lost another pawn. 02:20.650 --> 02:24.040 This is really, really silly right here. 02:24.040 --> 02:28.240 Actually, we can celebrate the fact that the opponent's pawns are fragmented. 02:28.750 --> 02:33.820 And, you know, the best move, one of the best moves would be this move. 02:34.840 --> 02:39.820 So even though we're currently two pawns down, we've we've got a much better pawn structure. 02:40.240 --> 02:44.020 Well, the opponents compromise their pawn structure with these double pawns. 02:44.590 --> 02:54.010 And if we succeed in regaining the pawn, you know, for example, of 96, then we've just virtually, 02:54.190 --> 02:55.480 you know, we've equalized here. 02:56.410 --> 03:06.070 So sometimes fragmenting the opponents pawns, trying to swap pawns in general is a good idea. 03:07.030 --> 03:13.750 And if the opponent is loathe to exchange pawns and plays before it, then they do give us something 03:13.750 --> 03:20.320 they give us in this particular position, a square we can use, celebrate our semiarid from phone. 03:21.190 --> 03:25.660 So we've got some pressure and OK, it's advantage is not so great. 03:25.660 --> 03:27.010 So that was still a good idea. 03:27.490 --> 03:38.050 So in general, these moves which try and exchange pawns rather than pieces need to be analyzed in great 03:38.050 --> 03:39.940 detail for their impact. 03:40.570 --> 03:44.860 So you could be getting some squares, you could be creating some structural damage. 03:45.340 --> 03:52.360 And ideally, you know, if you're able to also incur structural damage and get your power back, then 03:52.360 --> 03:54.730 you're on the way to equalizing all of a sudden. 03:55.390 --> 03:58.840 But the general principle when you're losing is to exchange 04:01.270 --> 04:03.130 pawns, not pieces. 04:05.890 --> 04:12.520 So, yeah, if they they're taken on a fight like this, OK, you've compromised their structure and 04:12.520 --> 04:21.070 actually you've got this and phone here and you can try and target this pawn and you've exchanged off 04:21.070 --> 04:21.940 some pawns. 04:23.530 --> 04:26.680 And it's actually more difficult now than before. 04:26.680 --> 04:29.460 For White to win, White's advantage is only a small advantage here. 04:30.970 --> 04:38.350 So in fact, you know why it's best bet on this pawn challenge in this particular position would be 04:38.530 --> 04:42.490 a move like Seefried to try and keep the structure intact. 04:43.840 --> 04:47.350 OK, sometimes you can try and make use of this amount of fall. 04:48.190 --> 04:53.890 But you know, it's still intact, though, so it's not as good as the other things I've just shown 04:53.890 --> 04:54.100 you. 04:54.700 --> 04:58.780 But the general principle holds that you definitely don't want to play a move. 04:59.710 --> 05:02.860 If you're down a pawn like this, you don't you don't want to exchange pieces. 05:02.860 --> 05:03.640 That's the general. 05:04.120 --> 05:13.000 More broader principle, you start asking these deeper questions about the possession and almost like. 05:14.070 --> 05:20.310 Drawing probability, drawing probabilities, so in games, especially if the opponents just left of 05:20.310 --> 05:27.720 two nights, it's virtually impossible for two nights and King was king to win unless unless you really 05:27.720 --> 05:29.290 make a huge amount of mistakes. 05:29.880 --> 05:37.110 So in general, if the opponent is left with hardly any pawns in an end game, your statistical probability 05:37.110 --> 05:38.490 of drawing increases. 05:38.820 --> 05:44.670 Therefore, your middle game strategy when you're down in terms of exchanging pieces should be to exchange 05:44.670 --> 05:51.810 of pawns and at least do investigations for all the resulting variations which might have a side effects. 05:53.230 --> 06:00.040 Of reducing the number of pawns on board, and even if you have to go a pawn pawn down, sometimes if 06:00.040 --> 06:05.560 there's other aspects like structural damage that gets facture, then and especially if you're getting 06:05.560 --> 06:11.020 a pawn back off of that, then you succeeded in effect in exchanging off pawns rather than pieces. 06:11.290 --> 06:15.370 And you're making the challenge of the opponent to win the game that much harder. 06:15.820 --> 06:22.780 So it is kind of an established general principle exchange pawns, not pieces. 06:22.780 --> 06:32.110 When you're down in material, at least do detailed investigations of -- related transactions to see 06:32.110 --> 06:39.340 the outcomes and the compensation that you might get in terms of pawn structure, generally piece pressure 06:39.760 --> 06:40.660 and other factors. 06:40.900 --> 06:47.300 But yeah, don't simplify with by getting pieces off in general when you're down. 06:47.800 --> 06:49.390 OK, that's so much.
