Hi there in this nation, I'd like to introduce you to a very, very useful role, the role of the square.
So with the rule of the square, we can determine if this pawn can actually be caught by the king without
having to calculate several moves ahead in this situation.
If the plane goes to fall, we can draw a square like this.
You see the square.
And essentially, if the black king can enter the square, if it has time to enter the square, it's
actually catching that passport.
And this quick calculation can really help our endgames, especially enforce the time controls, because
it can quickly help determine if the poor might need assistance from our king.
For example, if you can quickly answer that question, can the -- queen without any help or not,
then perhaps you could try a king move instead instead sometimes which could help when instead if we
go ahead now, depending on the situation.
So just to prove that rule in the square if a form.
So the king enters that square.
So at 5:00 here we have six king, these six, and it's been court.
So that ruler of the square is pretty critical to determine if the king can catch the poonam or not.
So the king's entering the square on this particular example.
So it's a very, very interesting road to save you having to calculate several moves ahead.
That roll of the square.
If you draw a little square before moving the pawn and see if the opponents king can enter the square.
OK, that's a.
