WEBVTT 00:01.410 --> 00:02.040 Hi there. 00:02.440 --> 00:08.580 And we're going to talk about chest evaluation skills, so we've talked a lot about calculation. 00:09.180 --> 00:20.010 Now, evaluation is actually often a kind of nudge to see further and in evaluating positions, you 00:20.010 --> 00:22.590 should be on the lookout for unprotected pieces. 00:23.650 --> 00:25.970 For example, the queen is not protected piece. 00:26.310 --> 00:29.580 This creates a kind of downside of the opponent's position. 00:30.870 --> 00:38.940 When you calculate variations, it's often just the tool to underline and expose downsides of the opponent's 00:38.940 --> 00:39.470 position. 00:39.960 --> 00:44.640 Here we can calculate forcing moves which lead us somewhere. 00:45.360 --> 00:53.730 And if we are aware even from the outset, what we're trying to underline or expose, it can push us 00:53.730 --> 00:55.200 that little bit further. 00:55.200 --> 01:02.050 That extra mile, which is actually the difference between seeing the advantage of the 40 moves or not. 01:02.970 --> 01:07.920 So our evaluation of this position, OK, on NetSpend to the Queen. 01:10.000 --> 01:17.710 Potentially, we've also got to be careful about this night, it's got some squares, this queen is 01:17.710 --> 01:21.300 attacking our nights right now. 01:22.240 --> 01:24.810 So to what do we do? 01:24.820 --> 01:30.400 What how do we respond to this kind of threat and in the position do we parry that fact? 01:30.400 --> 01:36.340 We try and move the NEUTZE, but if we move the night, hang on, horrible things might happen here 01:36.730 --> 01:37.830 and you start to notice. 01:37.840 --> 01:38.310 Hold on. 01:38.740 --> 01:40.240 Ninety seven King takes this. 01:40.280 --> 01:43.870 Is this actually a reasonable position or something. 01:44.950 --> 01:48.580 OK, we might be able to move on like there but then we might be losing a pawn. 01:48.880 --> 01:56.860 But check all the apparatus, let's go through the apparatus, the process of looking at the forcing 01:56.860 --> 01:59.170 moves, even the outrageous ones. 02:00.760 --> 02:06.550 So there are two or more checks had to consider, check all the checks, some of them are much better 02:06.550 --> 02:07.330 than others. 02:08.170 --> 02:14.140 The check on Jitu, there's two checks to G to this recall that that's not a promising path. 02:14.140 --> 02:19.540 We can kind of cut off that path and there's no need to evaluate even that position. 02:19.540 --> 02:22.120 Would you seem to be losing a rook for not nothing much. 02:22.840 --> 02:27.060 But when we look at other moves, there are inherent weaknesses of the last move. 02:27.070 --> 02:34.210 If we look at Rook one or Queen three as a set of witnesses there of last move that we can create if 02:34.210 --> 02:40.840 we play queen takes king size, then actually the king is neglecting H1. 02:40.840 --> 02:41.230 Right. 02:42.130 --> 02:46.180 But if we look at that, is that actually convincing her? 02:46.180 --> 02:48.700 Because actually, haven't they got a defense on H2? 02:48.700 --> 02:53.500 Now, if they if we play Rook H1, haven't they got rechange two? 02:53.680 --> 02:58.440 So this is not a convincing path either or a valuation might. 02:58.840 --> 03:02.410 And here, you know, that actually know, we don't have to look further. 03:03.040 --> 03:05.530 You can tell us when to stop as well as one to carry on. 03:05.740 --> 03:08.860 So let's let's look at the other checks now. 03:09.100 --> 03:10.360 So we look at each one. 03:10.360 --> 03:11.410 So this creates a weakness. 03:11.410 --> 03:14.670 On H3, the king is dragged away from H3. 03:14.710 --> 03:18.400 The wings of the last move is the neglect of H free. 03:18.760 --> 03:20.980 Now, here is where things get interesting. 03:21.610 --> 03:26.980 So in a way that went for the last move is also driving us to look a little bit further, to look a 03:26.980 --> 03:32.440 little bit further, that we've shortcut had some other checks because they just seem to offer not even 03:33.580 --> 03:34.930 a weakness of the last move. 03:35.230 --> 03:39.160 But here, OK, what can we see here in this position? 03:42.130 --> 03:45.520 The thing is now you might want to pause the video here for five seconds. 03:45.850 --> 03:46.810 I'll give you five seconds. 03:46.810 --> 03:48.580 Runs for the spin as long as you want. 03:49.090 --> 03:52.600 After can you see a great sequence for black hair? 03:53.710 --> 04:00.310 And you might also factor in the you know, the the kind of downside of White's position as well. 04:01.690 --> 04:06.370 Technology needs a cause, you know, a kind of benefit. 04:06.670 --> 04:10.060 The benefits underline downsides in chess is a major benefit. 04:10.060 --> 04:15.220 If you want to win games, you want to kind of underline celebrate downsides of the position. 04:15.940 --> 04:18.730 Now here, you know, queen size, age, free check. 04:19.090 --> 04:25.990 First of all, this allows a little bit more pursuit in its own right, because if rook age, too, 04:25.990 --> 04:29.800 doesn't that in itself create a weakness of the last move, doesn't it? 04:29.800 --> 04:33.510 Doesn't that not does it not neglect, Ephrem? 04:33.520 --> 04:34.350 Yes, it does. 04:34.630 --> 04:39.400 The answer to that question, it does neglect every rook to have queen takes. 04:39.550 --> 04:40.720 Francis will be meeting. 04:41.290 --> 04:42.370 You know, this would be mating. 04:43.090 --> 04:44.920 But what if they put the knights in France? 04:44.920 --> 04:46.420 Haven't we just lost a rook? 04:46.960 --> 04:53.830 But our early kind of evaluation of the downsides of the opponent's position might cause us to look 04:53.830 --> 04:55.210 a little bit further here. 04:56.200 --> 04:57.760 So I hope you can spot something. 05:01.230 --> 05:07.020 And that is Mike Jeoffrey, check and look at the discovery facts, the night has liberated Loncraine 05:07.020 --> 05:07.860 in this direction. 05:08.460 --> 05:10.290 So we're actually winning. 05:10.290 --> 05:11.450 The queen won't resign. 05:11.460 --> 05:13.350 The queen is lost at the king moves. 05:13.350 --> 05:14.220 We take the queen. 05:15.810 --> 05:25.500 So we see that the process of evaluation and especially witness of the last move encourages us to kind 05:25.500 --> 05:27.050 of have some targets as well. 05:27.060 --> 05:28.620 It's not a calculation of calculations. 05:28.620 --> 05:34.350 I think we have some underlying downsides to celebrate at opponents pace. 05:34.350 --> 05:39.300 We want to try and work out sometimes how to win that or some other key safety issues. 05:39.690 --> 05:42.510 The weaknesses of the last move also push us forward. 05:43.260 --> 05:47.280 So the evaluation shortcuts sometimes we value and we say, well, there's not even a witness. 05:47.280 --> 05:48.450 The last move has nothing. 05:48.450 --> 05:53.430 So we stop there and we look at other paths until we find the right checks. 05:53.430 --> 05:55.530 There's often a lot of checks to consider. 05:55.830 --> 05:58.500 You've got to find the best possible checks, check all checks. 05:58.740 --> 06:01.800 Some of them give advantage and some don't. 06:02.730 --> 06:06.330 This is a position in which, you know, if this was Shunji as opposed to, you might be giving him 06:06.600 --> 06:07.440 the most flash. 06:07.470 --> 06:11.490 You know, Queensferry actually it doesn't deliver on this occasion free. 06:11.490 --> 06:16.770 And it was just Lousie Queen basically it's actually Rook one. 06:16.770 --> 06:17.820 So yeah. 06:17.820 --> 06:21.590 Calculation evaluation is those endpoints. 06:21.720 --> 06:28.610 When it's a look further or not, Mangahas Coalson quite often shortcuts the employees when he says, 06:28.620 --> 06:32.640 well, you know, the opponents got counterplay. 06:32.640 --> 06:40.320 How this looks scary might not go in that direction of calculating further, but yet you're driven further 06:40.320 --> 06:42.930 and you're driven to celebrate townsite. 06:42.930 --> 06:46.860 So he was celebrating that queen on age sex being unprotected. 06:47.250 --> 06:54.630 OK, so I hope this kind of gives you a glimpse, a valuation and how valuation, especially with the 06:54.630 --> 07:01.290 opponents downsides of the position staright can be a handy kind of conceptual tool to make use of. 07:02.010 --> 07:03.750 OK, pretty much.
