Hi there.

00:01.830 --> 00:08.790
In this election, we look at another casting role, which is there must be space between the king and

00:08.790 --> 00:10.900
the rook, only space, no pieces.

00:11.520 --> 00:15.440
So, for example, here, there's this neutze in the way.

00:15.960 --> 00:18.600
So whites cannot actually legal legally.

00:18.600 --> 00:19.850
Castle queen size.

00:19.860 --> 00:27.780
You can't do that because the knights here and the same with black hair can't cancel on the king's side

00:27.780 --> 00:31.560
because of that bishop obstructing between king and rock.

00:31.560 --> 00:32.820
It's between King and rook.

00:33.830 --> 00:39.230
There can't be a peace there, so in this position of view, if we want to control Queensland, we could

00:39.230 --> 00:45.050
move on night and say they cancelled Queensland, which is possible.

00:45.950 --> 00:51.840
We could cancel Queensland, which is possible because I know it's also obstructed that check.

00:51.860 --> 00:53.330
So we haven't passed through check.

00:53.330 --> 00:58.880
We've we've been able to cancel Queensland that let's look at this again.

01:01.220 --> 01:01.760
So.

01:02.980 --> 01:03.490
Say.

01:04.700 --> 01:12.020
We counsel Kingside, the opponent cannot counsel Kingside because of the bishop, there can't be anything

01:12.020 --> 01:16.790
between the camera if they move their bishop and let's say we move all night, then they can either

01:16.790 --> 01:24.110
counsel queen side or Kingside here, Queen Queensland, because there's no peace between King and Rock.

01:24.110 --> 01:27.440
They're all kingside because there's no peace between the king and rock.

01:27.890 --> 01:32.710
So yes, to recap then to reinforce the rules of crossing, there's quite a few, isn't there?

01:33.470 --> 01:37.520
There can't be any obstruction between king and rock.

01:38.690 --> 01:40.600
So there is there is an obstruction here.

01:41.330 --> 01:44.630
There can't be a pesky peace putting us in check at the end of it.

01:46.400 --> 01:47.920
Say, say there was a bishop there.

01:47.930 --> 01:49.790
We couldn't conceive queen side either.

01:50.810 --> 01:51.980
Say there was a bishop there.

01:51.980 --> 01:55.100
We couldn't conceive queen side either because we'd be passing through check.

01:56.570 --> 02:01.340
If there was a bishop here and there wasn't an obstruction, then we could still consequence.

02:01.340 --> 02:03.050
Like the king didn't go through check.

02:04.070 --> 02:10.040
If a king had previously moved before and move back then we can't cause anywhere if our rook on the

02:10.040 --> 02:11.780
queen side to move somewhere moved back.

02:11.780 --> 02:12.310
We can't.

02:12.480 --> 02:18.140
Can't cos on the queen side and the same for this rook, if it moved somewhere, moved back, we can't

02:18.140 --> 02:19.400
cross that side.

02:20.690 --> 02:26.330
So if both the move somewhere moved back, we can't control anywhere either Queensland kingside.

02:26.660 --> 02:28.760
So yes, the crossing rules are pretty involved.

02:30.140 --> 02:34.370
But once you get the hang of them hopefully you'll be fine.

02:34.370 --> 02:40.010
Even in your casual games where you have to enforce these rules with your casual opponents online,

02:40.010 --> 02:41.060
you won't be able to do.

02:42.010 --> 02:47.410
Illegal moves, so the Kosslyn rules will be enforced for you.

02:47.990 --> 02:48.580
OK.

02:49.590 --> 02:50.130
That's so much.
