Hi there.
In this election, we're going to use a very, very important technique for checkmating the king as
efficiently as possible.
If we bring all King up to AFTA, let's say King you for now check and let's say King differe for a
moment.
We can play Racan for and this was strength's, the king's kind of rectangle.
So the king is confined in these kind of squares.
That's like the king's rectangle right now.
That's the king the two.
And now we can can find even more if we look at the king's rectangle.
Now the king has these squares to play with right now.
King see, then we can bring the king, let's say King B to King Day, to King eight, to King C two.
And we've really confined the King's Square now to a single square.
And it's rook free.
Checkmate.
Let's see that again.
Kind of magical, isn't it?
We don't have to spend ages driving the king to the back row.
So King E four, we said check king differe if King EF five instead.
Then King Avery of King E5, a very efficient way here, instead of checking to get the king step backwards
and eventually to Frank, there's a much quicker way, which is rook the in this position.
So you're driving the king into a smaller kind of rectangle of the king at five, again, without any
checks.
We just play Rook E for driving the king into a smaller rectangle.
And here again, Rook had four.
So all of these subtle little moves we've actually been restricting the king and we're making huge progress
because the king's rectangle is restricted.
And now we do take time to move on king here and then ask the panel what they're doing in this position
of the king Afri.
So keep waiting and here we can finally restrict the king again.
We've got them on this side of the board now and we just bring down Paul King and we're getting very,
very close to checkmate.
This is a key waiting we've had.
So they have to go to change things and I'm looking for Checkmates, so it's a very, very interesting
process of kind of not using any chance.
This is the really professional way of doing things.
So without using any chance, you were just noting that the Kings got a limited bit of activity, a
rectangle, so rook and forhow without any checks asking where it's going.
If King Seefried, then we can have a look at this where the king just helps a little bit and then this
restricts that King's rectangle and then King Sivewright, we've got the king to be mated on this road.
Tensioning so like that.
So this is a very, very efficient method of shrinking the king's rectangle.
If we go with King E five to start off with King Afrik, let's have a look at this again.
This method Rook A5 restricts the king's rectangle here.
And again, we're restricted in the king's ranks and we rook a form and then here a key weighting move.
And then we're driving the king into restriction here.
This restricts the king, that key rectangle and now the king's confined, extremely confined, just
waiting for assistance for the final chapter here.
So this is a key waiting move.
If King a framework, one that means so here.
Yeah.
So it's a very, very nice method, not involving a lever of checks.
You just kind of restricting the opponents King's rectangle.
So just to recap, once all the main pattern trilemma.
So Chank.
And if King defraying look out for it's really a restrictive move asking him what to do if we restrict
again and we're slowly making that rectangle just shrinking, we're shrinking that right.
And what the king has got.
So it's very, very, very efficient.
And for example, here is checkmate.
So I hope you've got the basic gist here.
It's restricting King's rectangle of escape.
It's the most efficient method.
There is a far less efficient method.
If you are worried about this, there is a far less efficient method which you could use, which.
If you're in blitz games, it's it's not that great, but this is the slow donkey method up the mountain
where you could decide whether you want to take checkmate the opponents on the franc.
OK, so the slow donkey method here, you play like this and you're waiting for them to play there so
you can drive them one more robot board.
But then you end up with this kind of loop like this where you have to go one road at a time and you
can see it's pretty inefficient.
You have to use a waiting move here and it's quite a lot of moves.
But you will get there in the end.
You will get there in the end.
But here you want to, like, be efficient here at least.
So waiting for them for this drive.
More, more roback.
You can see it's a less it's a less efficient method than what we saw, far less efficient here.
We need the weighting move here to wait for King.
These things we can do things, but yeah, we can go like this.
If you want to use the donkey method don't up the mountain then you can use this for if they go here
then we're checking them to go back so they could persist.
But the a number of moves, this is a lot more moves, a lot more moves.
Yeah, I mean, this is this is Michael Donkey, my friend.
OK, so which does the job I mean, a win is a win is a win and it's an expression.
Yes, but let's have a look.
So this method of the shrinking rectangle is the preferred one, because especially if you're up against
clock pressure and a professional game.
So not having a particular bias for having to get the king up of there, you're just looking at the
king's rectangle more you restrict in the game, more and more in a virtual rectangle, which kind of
shrinks if you look at this is shrinking, by the way, of playing with shrink that rectangle.
In fact, we're not by striving, looking at all up there, we you know, we're going to make it the
most efficient such thing.
So here we're going.
And when I'm winning very, very efficiently, because we haven't been biased at all for mating at the
back row.
So, OK, so there's the donkey methods, which I don't recommend.
You should really train on the shrinking rectangle method and.
Just just like this, go with King E5 sucking at free here and so we're not biased, we don't care if
the king comes this way, we've got that rectangle set up and we're shrinking it.
So this is systematic shrinking and then we're totally restricting the there.
And you can see how much more efficient this is.
So the shrinking rectangle method is the one I'd recommend, not the donkey method.
Try and practice with a friend or chess computer or that relative, that shrinking method the most efficient
way because say you play chess etc online or fast chess and you really need to win quite quickly.
So it's actually kind of important to know the optimal method, not the donkey method.
So to recap, good luck in practicing from this position as the example, the rectangle method, shrinking
rectangle, no bias when you're making the king it just shrinking that rectangle around the opponent's
king quite rapidly and so much.
