Either in this position along to show you the Vancouver position, this is a way for black to draw.
So if white plays king, see five black guys check and see how black keeps the checks going here.
And for example, this position keep the charts going.
But here we keep in contact with that pawn.
And this is the best play.
It's impossible for whites to win.
So it's been studied by Frank Hura and it's actually impossible to win if we play recaps.
If we didn't play recaps, thanks.
We played against one.
This actually loses, for example, Czech and then here and then the pawn is making progress.
We're essentially going to lose this position, for example.
Eventually we're going to lose you know, they're going to build a bridge here and queen that poem.
So you make contact, you keep contact with that pawn.
And in this particular position, it should be just a draw if a seven Roquet six.
So you get behind that poem, you stop any tracks like Rukia Check and queening, so if you if you played,
for example.
King f7 the went playing eight track and then Queen.
So you get behind the -- immediately, so the -- star on seven and here it's impossible for one
to use any trick when the king is crucially on G7 here it can be sometimes on eight, seven as well.
But if it's on F7, then they would have a trick in room eight because then if you imagine taking the
-- they got.
Rule seven, winning the rook after.
And so the king is crucially in the vanguard position on G-7.
Or H7.
That's the crucial bit as well to remember.
So here in this position, if kinky sex, we just carry on the checks and why it's not able to make
progress.
So if you can get to the bank position, if you are playing black and they had a rook's --, you want
you king on the other side of the board.
So just to make that a little bit clearer, say say you're black, you're black and you're king wasn't
on the other side of the board.
So we reached this position.
Well, here we have Brooke one, and thankfully they haven't got any tricky rock move to say say we
did blunder with all king like here, Brooke, FHA doesn't work or looks able to, you know, take on
the poem.
But if I King was on F7, they'd have eight.
And then the point is, you know, had they had that, they will track.
So basically we're talking about from the black perspective sometimes when defending against the ponies
Rook's poem.
You need your king on this side of the board so that rook track is not working and you have to make
sure that you maintain either like perpetual checks.
Or an attack against the --.
So here, for example, would have sex.
So you don't really count if a seven, you're going to get behind that --, there's no tricks for
whites.
Here, it's it's just a draw, so the Vancouver position is very, very important to know about defending
against a Ruxpin, I hope.
That's kind of illustrating the concept a little bit.
It's an important position to know about for drawing against Aerospatiale.
Kheng, crucially, has to be on the other side of the board.
You have to sometimes use perpetual checks and sometimes you have to keep contact with with whom you're
trying to encourage a position like this where it's committed.
And then you got a perpetual check situation without any tricks from whites to win your rook because
your king's here or hair and your rook's ready to catch the form if there's any check.
So you're behind pawn in this one once the pawn is on some Frank, OK, and so much.
