00:00.900 --> 00:07.120
Hi there in this nation, I'd like to introduce you to a very, very useful role, the role of the square.

00:07.920 --> 00:16.170
So with the rule of the square, we can determine if this pawn can actually be caught by the king without

00:16.170 --> 00:21.030
having to calculate several moves ahead in this situation.

00:21.420 --> 00:27.210
If the plane goes to fall, we can draw a square like this.

00:29.100 --> 00:30.210
You see the square.

00:30.960 --> 00:38.520
And essentially, if the black king can enter the square, if it has time to enter the square, it's

00:38.520 --> 00:41.780
actually catching that passport.

00:42.390 --> 00:49.530
And this quick calculation can really help our endgames, especially enforce the time controls, because

00:49.590 --> 00:54.810
it can quickly help determine if the poor might need assistance from our king.

00:54.810 --> 01:02.780
For example, if you can quickly answer that question, can the -- queen without any help or not,

01:03.390 --> 01:12.060
then perhaps you could try a king move instead instead sometimes which could help when instead if we

01:12.060 --> 01:15.600
go ahead now, depending on the situation.

01:15.960 --> 01:20.040
So just to prove that rule in the square if a form.

01:22.260 --> 01:24.070
So the king enters that square.

01:25.290 --> 01:30.450
So at 5:00 here we have six king, these six, and it's been court.

01:31.140 --> 01:39.790
So that ruler of the square is pretty critical to determine if the king can catch the poonam or not.

01:40.680 --> 01:44.260
So the king's entering the square on this particular example.

01:44.670 --> 01:50.520
So it's a very, very interesting road to save you having to calculate several moves ahead.

01:50.880 --> 01:51.780
That roll of the square.

01:51.780 --> 01:57.420
If you draw a little square before moving the pawn and see if the opponents king can enter the square.

01:58.140 --> 02:00.060
OK, that's a.
