Hi there.
And we're going to talk about chest evaluation skills, so we've talked a lot about calculation.
Now, evaluation is actually often a kind of nudge to see further and in evaluating positions, you
should be on the lookout for unprotected pieces.
For example, the queen is not protected piece.
This creates a kind of downside of the opponent's position.
When you calculate variations, it's often just the tool to underline and expose downsides of the opponent's
position.
Here we can calculate forcing moves which lead us somewhere.
And if we are aware even from the outset, what we're trying to underline or expose, it can push us
that little bit further.
That extra mile, which is actually the difference between seeing the advantage of the 40 moves or not.
So our evaluation of this position, OK, on NetSpend to the Queen.
Potentially, we've also got to be careful about this night, it's got some squares, this queen is
attacking our nights right now.
So to what do we do?
What how do we respond to this kind of threat and in the position do we parry that fact?
We try and move the NEUTZE, but if we move the night, hang on, horrible things might happen here
and you start to notice.
Hold on.
Ninety seven King takes this.
Is this actually a reasonable position or something.
OK, we might be able to move on like there but then we might be losing a pawn.
But check all the apparatus, let's go through the apparatus, the process of looking at the forcing
moves, even the outrageous ones.
So there are two or more checks had to consider, check all the checks, some of them are much better
than others.
The check on Jitu, there's two checks to G to this recall that that's not a promising path.
We can kind of cut off that path and there's no need to evaluate even that position.
Would you seem to be losing a rook for not nothing much.
But when we look at other moves, there are inherent weaknesses of the last move.
If we look at Rook one or Queen three as a set of witnesses there of last move that we can create if
we play queen takes king size, then actually the king is neglecting H1.
Right.
But if we look at that, is that actually convincing her?
Because actually, haven't they got a defense on H2?
Now, if they if we play Rook H1, haven't they got rechange two?
So this is not a convincing path either or a valuation might.
And here, you know, that actually know, we don't have to look further.
You can tell us when to stop as well as one to carry on.
So let's let's look at the other checks now.
So we look at each one.
So this creates a weakness.
On H3, the king is dragged away from H3.
The wings of the last move is the neglect of H free.
Now, here is where things get interesting.
So in a way that went for the last move is also driving us to look a little bit further, to look a
little bit further, that we've shortcut had some other checks because they just seem to offer not even
a weakness of the last move.
But here, OK, what can we see here in this position?
The thing is now you might want to pause the video here for five seconds.
I'll give you five seconds.
Runs for the spin as long as you want.
After can you see a great sequence for black hair?
And you might also factor in the you know, the the kind of downside of White's position as well.
Technology needs a cause, you know, a kind of benefit.
The benefits underline downsides in chess is a major benefit.
If you want to win games, you want to kind of underline celebrate downsides of the position.
Now here, you know, queen size, age, free check.
First of all, this allows a little bit more pursuit in its own right, because if rook age, too,
doesn't that in itself create a weakness of the last move, doesn't it?
Doesn't that not does it not neglect, Ephrem?
Yes, it does.
The answer to that question, it does neglect every rook to have queen takes.
Francis will be meeting.
You know, this would be mating.
But what if they put the knights in France?
Haven't we just lost a rook?
But our early kind of evaluation of the downsides of the opponent's position might cause us to look
a little bit further here.
So I hope you can spot something.
And that is Mike Jeoffrey, check and look at the discovery facts, the night has liberated Loncraine
in this direction.
So we're actually winning.
The queen won't resign.
The queen is lost at the king moves.
We take the queen.
So we see that the process of evaluation and especially witness of the last move encourages us to kind
of have some targets as well.
It's not a calculation of calculations.
I think we have some underlying downsides to celebrate at opponents pace.
We want to try and work out sometimes how to win that or some other key safety issues.
The weaknesses of the last move also push us forward.
So the evaluation shortcuts sometimes we value and we say, well, there's not even a witness.
The last move has nothing.
So we stop there and we look at other paths until we find the right checks.
There's often a lot of checks to consider.
You've got to find the best possible checks, check all checks.
Some of them give advantage and some don't.
This is a position in which, you know, if this was Shunji as opposed to, you might be giving him
the most flash.
You know, Queensferry actually it doesn't deliver on this occasion free.
And it was just Lousie Queen basically it's actually Rook one.
So yeah.
Calculation evaluation is those endpoints.
When it's a look further or not, Mangahas Coalson quite often shortcuts the employees when he says,
well, you know, the opponents got counterplay.
How this looks scary might not go in that direction of calculating further, but yet you're driven further
and you're driven to celebrate townsite.
So he was celebrating that queen on age sex being unprotected.
OK, so I hope this kind of gives you a glimpse, a valuation and how valuation, especially with the
opponents downsides of the position staright can be a handy kind of conceptual tool to make use of.
OK, pretty much.
