1
00:00:00,979 --> 00:00:04,529
Are you wondering why chess
is more exciting than checkers?
2
00:00:04,529 --> 00:00:05,600
Well for one thing
3
00:00:05,600 --> 00:00:06,600
some of the chess pieces
4
00:00:06,600 --> 00:00:07,990
can move a lot farther
5
00:00:07,990 --> 00:00:09,580
than they can in checkers.
6
00:00:09,580 --> 00:00:11,599
Today, you get to be a rook!
7
00:00:11,599 --> 00:00:13,889
"But wait a minute, I want to be a fireman!"
8
00:00:13,889 --> 00:00:16,199
Ok, Ok, you can be a fireman later in life
9
00:00:16,199 --> 00:00:18,840
but today, I just want you to be a rook.
10
00:00:18,840 --> 00:00:21,230
The rook can move in four different directions.
11
00:00:21,230 --> 00:00:22,630
The rook can go up!
12
00:00:22,630 --> 00:00:23,720
The rook can go down!
13
00:00:23,720 --> 00:00:25,710
The rook can go left!
14
00:00:25,710 --> 00:00:26,710
The rook can go right!
15
00:00:26,710 --> 00:00:28,329
And for any of you kids out there
16
00:00:28,329 --> 00:00:29,470
that like to read maps
17
00:00:29,470 --> 00:00:32,579
that would be North, South, East and West.
18
00:00:32,579 --> 00:00:34,510
The rook has lots of choices here.
19
00:00:34,510 --> 00:00:36,270
The rook can go just a little bit
20
00:00:36,270 --> 00:00:38,719
or all the way to the edge of the chessboard!
21
00:00:38,719 --> 00:00:41,690
So, my rook can move up one, that's possible
22
00:00:41,690 --> 00:00:44,090
or all the way to the edge of the board.
23
00:00:44,090 --> 00:00:46,519
Or the rook could have stopped
somewhere in between.
24
00:00:46,519 --> 00:00:48,820
For example, the rook could have gone up
two squares
25
00:00:48,820 --> 00:00:50,840
or even gone up three squares
26
00:00:50,840 --> 00:00:52,090
it would have been your choice!
27
00:00:52,090 --> 00:00:54,560
Of course, you can't
go off the edge of the chessboard
28
00:00:54,560 --> 00:00:56,440
that would be crazy!
29
00:00:56,440 --> 00:00:57,440
In this position
30
00:00:57,440 --> 00:00:59,210
I want you to try to count
31
00:00:59,210 --> 00:01:00,399
how many different squares
32
00:01:00,399 --> 00:01:01,100
the rook can move to?
33
00:01:01,100 --> 00:01:03,100
*pause your video and count!*
34
00:01:03,100 --> 00:01:04,880
What number did you get?
35
00:01:04,880 --> 00:01:07,300
Well, if you got the answer 14
36
00:01:07,300 --> 00:01:08,300
you are on the way
37
00:01:08,300 --> 00:01:09,300
to being a chess master!
38
00:01:09,300 --> 00:01:12,640
Let's count together,
one, two, three, and four.
39
00:01:12,640 --> 00:01:15,790
Let's go down
five, six, and seven,
40
00:01:15,790 --> 00:01:16,840
but we're not done!
41
00:01:16,840 --> 00:01:18,190
We can go left!
42
00:01:18,190 --> 00:01:20,860
Eight, nine,
ten, and eleven.
43
00:01:20,860 --> 00:01:21,860
To the right...
44
00:01:21,860 --> 00:01:24,030
12, 13, and 14.
45
00:01:24,030 --> 00:01:25,470
If you got more than 14
46
00:01:25,470 --> 00:01:26,470
chances are you tried
47
00:01:26,470 --> 00:01:28,220
to count the square the rook starts on
48
00:01:28,220 --> 00:01:30,620
and that doesn't really count.
49
00:01:30,620 --> 00:01:32,880
Are you ready for a challenge question?
50
00:01:32,880 --> 00:01:36,110
The rook is actually able
to move to any square
51
00:01:36,110 --> 00:01:38,080
on the chessboard in two turns
52
00:01:38,080 --> 00:01:39,720
no matter which one you pick!
53
00:01:39,720 --> 00:01:40,720
Go ahead!
54
00:01:40,720 --> 00:01:42,390
Think of a square!
55
00:01:42,390 --> 00:01:43,750
Did you think of the square g7?
56
00:01:43,750 --> 00:01:45,150
Well, probably not...
57
00:01:45,150 --> 00:01:46,320
I was just guessing!
58
00:01:46,320 --> 00:01:48,400
But in any case, let's just start with g7
59
00:01:48,400 --> 00:01:50,470
and see if you can make a plan
60
00:01:50,470 --> 00:01:52,820
to get there in two moves.
61
00:01:52,820 --> 00:01:54,090
Now you might think to start
62
00:01:54,090 --> 00:01:55,500
by traveling to the right
63
00:01:55,500 --> 00:01:57,060
but if you go all the way
64
00:01:57,060 --> 00:01:58,280
to the edge of the board
65
00:01:58,280 --> 00:01:59,280
you're not going to be able to get
66
00:01:59,280 --> 00:02:00,850
to g7 on the next turn.
67
00:02:00,850 --> 00:02:02,470
So, let's go back
68
00:02:02,470 --> 00:02:04,380
and maybe find a different way
69
00:02:04,380 --> 00:02:05,590
to get to g7.
70
00:02:05,590 --> 00:02:08,110
Instead, let's go to the right
71
00:02:08,110 --> 00:02:11,069
but let's stop after only 2 squares.
72
00:02:11,069 --> 00:02:12,140
And if we do that
73
00:02:12,140 --> 00:02:13,260
on our next turn
74
00:02:13,260 --> 00:02:14,480
we can travel forward
75
00:02:14,480 --> 00:02:17,269
and land on the red square.
76
00:02:17,269 --> 00:02:19,709
Was there another way to get to g7?
77
00:02:19,709 --> 00:02:22,319
Well, there was, I'm sure you found it!
78
00:02:22,319 --> 00:02:24,170
The rook could go forward
79
00:02:24,170 --> 00:02:26,810
and stop on the square e7
80
00:02:26,810 --> 00:02:29,420
and then to the right and land on g7.
81
00:02:29,420 --> 00:02:30,820
Notice how I'm naming squares!
82
00:02:30,820 --> 00:02:32,329
I'm using the letter first
83
00:02:32,329 --> 00:02:33,770
and the number second.
84
00:02:33,770 --> 00:02:34,989
This square is g7
85
00:02:34,989 --> 00:02:37,290
because it sits on the g "file".
86
00:02:37,290 --> 00:02:40,159
That's what we call
the up and down rows, "files"!
87
00:02:40,159 --> 00:02:44,150
And, the square also sits
on "rank" number 7
88
00:02:44,150 --> 00:02:45,520
that's what we call side to side rows
89
00:02:45,520 --> 00:02:46,989
we call them "ranks".
90
00:02:46,989 --> 00:02:48,920
The rook had two different ways
91
00:02:48,920 --> 00:02:50,609
to get to g7.
92
00:02:50,609 --> 00:02:52,890
Go ahead, try any other square on the board
93
00:02:52,890 --> 00:02:54,299
and then see if you can figure out a way
94
00:02:54,299 --> 00:02:57,760
for the rook to get there in two moves.
95
00:02:57,760 --> 00:02:59,129
We'll do one more together!
96
00:02:59,129 --> 00:03:00,810
How about a6?
97
00:03:00,810 --> 00:03:03,230
Do you see a way to get there in two moves?
98
00:03:03,230 --> 00:03:04,840
Well, we can go left
99
00:03:04,840 --> 00:03:06,950
all the way to the edge of the board.
100
00:03:06,950 --> 00:03:08,079
And then on the next turn
101
00:03:08,079 --> 00:03:10,870
the rook could travel up and land on a6.
102
00:03:10,870 --> 00:03:11,870
Let's go back!
103
00:03:11,870 --> 00:03:14,110
Of course the other way was to go forward
104
00:03:14,110 --> 00:03:15,999
but stop after only two squares
105
00:03:15,999 --> 00:03:17,109
and then go to the left
106
00:03:17,109 --> 00:03:19,769
and again we land on a6.
107
00:03:19,769 --> 00:03:20,769
The final thing
108
00:03:20,769 --> 00:03:22,040
that I want you to learn about rooks
109
00:03:22,040 --> 00:03:24,109
(before you become firemen that is)
110
00:03:24,109 --> 00:03:26,459
is how the rook is able to capture.
111
00:03:26,459 --> 00:03:28,060
It's actually very simple.
112
00:03:28,060 --> 00:03:29,290
The rook acts a little bit like
113
00:03:29,290 --> 00:03:31,260
a bowling ball and runs over
114
00:03:31,260 --> 00:03:32,510
the enemy piece!
115
00:03:32,510 --> 00:03:33,939
Let's see that in action!
116
00:03:33,939 --> 00:03:36,200
Here, I gave Black two rooks
117
00:03:36,200 --> 00:03:37,540
and White only has one
118
00:03:37,540 --> 00:03:38,749
but that's ok!
119
00:03:38,749 --> 00:03:41,029
We're about to do a couple of captures.
120
00:03:41,029 --> 00:03:42,029
These two Black rooks
121
00:03:42,029 --> 00:03:44,250
are on the same file, the b file.
122
00:03:44,250 --> 00:03:46,340
Let's have the rook on b7
123
00:03:46,340 --> 00:03:47,560
travel down the board
124
00:03:47,560 --> 00:03:49,689
and land on the square, b4.
125
00:03:49,689 --> 00:03:51,170
Now, these two rooks
126
00:03:51,170 --> 00:03:52,670
are aiming at each other.
127
00:03:52,670 --> 00:03:54,760
It's like a game a flashlight tag.
128
00:03:54,760 --> 00:03:57,109
But using my bowling ball idea
129
00:03:57,109 --> 00:03:58,730
here comes the White rook!
130
00:03:58,730 --> 00:04:01,319
The White rook travels all the way over
131
00:04:01,319 --> 00:04:02,400
and when the White rook
132
00:04:02,400 --> 00:04:04,370
runs into a Black piece
133
00:04:04,370 --> 00:04:05,370
he can knock it over
134
00:04:05,370 --> 00:04:07,349
(in this case take it off the board)
135
00:04:07,349 --> 00:04:09,239
but the rook has to stop.
136
00:04:09,239 --> 00:04:10,719
You don't jump over the Black rook
137
00:04:10,719 --> 00:04:12,879
and you certainly don't keep going.
138
00:04:12,879 --> 00:04:14,590
Once you capture an enemy piece in chess
139
00:04:14,590 --> 00:04:16,030
you always have to stop.
140
00:04:16,030 --> 00:04:18,220
You can never capture two pieces at once.
141
00:04:18,220 --> 00:04:20,130
Now it's Blacks turn.
142
00:04:20,130 --> 00:04:21,660
Do you see a way that Black
143
00:04:21,660 --> 00:04:23,640
could capture back the White rook?
144
00:04:23,640 --> 00:04:25,389
Well of course!
145
00:04:25,389 --> 00:04:26,389
This Black rook could
146
00:04:26,389 --> 00:04:27,389
travel up the board
147
00:04:27,389 --> 00:04:28,940
run over the White rook
148
00:04:28,940 --> 00:04:31,030
and then he has to leave the chessboard.
149
00:04:31,030 --> 00:04:32,850
You just saw your very first example
150
00:04:32,850 --> 00:04:33,910
of a "trade".
151
00:04:33,910 --> 00:04:35,660
Each side got a rook!
152
00:04:35,660 --> 00:04:37,540
Let's review what we learned today...
153
00:04:37,540 --> 00:04:39,630
First of all, rooks can go up and down
154
00:04:39,630 --> 00:04:40,690
left and right.
155
00:04:40,690 --> 00:04:42,480
They can go as far as they want to
156
00:04:42,480 --> 00:04:44,170
and they're able to capture
157
00:04:44,170 --> 00:04:45,880
by running into the enemy piece
158
00:04:45,880 --> 00:04:48,100
and taking that piece off the board.
159
00:04:48,100 --> 00:04:49,660
We didn't learn how to become a fireman
160
00:04:49,660 --> 00:04:51,390
maybe we'll do that in our next lesson!
161
00:04:51,390 --> 00:04:51,890
Maybe not...
