Hi there.
Continuing our theme of the back bromates, we see that there's a sort of like theoretical downside.
The king hasn't got too many squares the king is not able to get to.
It seems blocked in by age 22.
So even though it's not --'s, it's still blocked in.
And the opponent here, this is from a game constant Auburn against has Kramer, an opponent here,
played Bishop takes E5 not suspecting anything was up.
Now, if I give you five seconds, pause the video.
Can you spot a backroad?
Checkmate.
And there's also another little lesson here as well.
I'm going to talk about that, which is very important in chess.
OK, I hope you spotted it for a thousand points, there is actually a chat here, believe it or not,
it looks as though the bishops covering AF1.
So it looks as though you can't play this.
But is that really the case?
Isn't this checkmate because the bishop is Penns to the king?
This is a pen.
This is called a tactical pen.
When something is pinned to the king, if it's pinned to the king, it's an absolute pen.
And in fact, there's an expression in chess the power of the pen piece is illusionary.
So, in fact, whenever you see a piece pinned to the opponent's king like this, you've got to imagine
as though it's an illusion.
It's not really controlling these squares.
It's only controlling this square where it's not Pendle on that line, but it can't go.
It's an illusion that it has control over a train, EF1, these are illusions.
So in fact, we're proving the downside here of why its position by playing rock.
Have one check and mate, it's checkmate.
The Misspend.
So this is another back from my example.
Yeah.
The back room is a frequent visitor for winning games of chess, so that's why it's so important as
your first mating pattern.
So be able to master these examples.
And again, the principle is in any given position, we really do need to check all our checks, our
captures and our threats of one.
And so basically the high priority forcing moves which will limit the opponent's replies when we calculate
so-called calculate moves in advance.
Kasparov was annoyingly, you know, kept ask the question how many moves ahead you calculate?
And, you know, he did say, you know, it depends on the position.
Some positions you can calculate very far and ahead because there's not too many choices.
Bobby Fischer, the American chess legend, said the same.
You know, sometimes you don't have to calculate all these different choices for the opponent.
So it makes it easy to calculate many moves ahead.
Your duty when you see a chess position is to at least calculate the essential forcing move variations,
the ones where there were very limited replies just in case you can win by force.
So yeah, here Rook have one is much stronger now.
It's checkmate is much stronger than taking here.
So sometimes the more subtle moves when you the games, the unexpected, the tales of the unexpected.
So Rook, if one is checkmate here, I hope you enjoyed this one and found that.
And so much.
