Alright, so you want to look at the
solution of this.
So let's, let's try to solve it.
This is not the only possible argument.
But let's say, let's try to see what's
going on.
So if blue goes first that's left.
Then, then there's only two edges
available for blue and there more or less
the same.
So blue will cut this.
Now if you think about it and therefore
thi, this right edge, this red edge up
here is, floats off.
Right can either do this or this.
But right's best move is to move here,
because, if right doesn't cut this now,
then blue will cut down the blue below it
next time.
And then right will, will be without a
move.
So right that's the best move for right
after blue does this.
So let, let, let's label these 1 2.
Then, then blue left only has 1 move left.
So that's got to be this one 3.
And then right only has 1 move left so
that's get cut, that's 4.
And now it's blue's turn.
It's left's turn.
No moves available, so left loses.
So if left goes first then left loses.
Alright, let's take a look and try to see
what happens if right moves first.
Right moves first.
Again, you can either look at all possible
cases or you can look at it and try to
figure out what the best opening move for
right is.
And the best opening move for right is
either this one or this one.
Because, because of this, this threat
from, from left to chop down below and,
and get rid of that right move, right may
as well take this move while, while he or
she can.
Now, left at this point might as well chop
down a right and so that happens.
And now this right is unavailable.
This all flows up off the page.
Let's see if now left.
It's now rights turn so this was 1, 2.
Right's turn is 3.
Right cuts that.
And now left cuts this.
And now, well, it's rights turn and
there's no moves, so right loses.
Going back to the original picture.
This says that if right goes first, right
loses.
Okay, so if you got this, great.
Make up other things and, and try them out
for, for yourself.
It.
If you have some difficulty with that let
us know what, what the problems were.
Go through the solutions carefully, and
see if you can't fi, pizz, puzzle it out.
And, and we'll see you all next time, with
week two.
Take care.
