Okay. 
Games without chance a little short one 
on 1b. 
Loopy games. 
Now, there's a famous comedy skit, about 
argument. 
And these two people sit down and they 
have an argument, and one person says, 
look argument is not just about 
contradicting one another. 
And the other person says yes it is, no 
it is, yes it is, no it is, yes it is. 
This is the example of famous loopy game 
that children like to play. 
Although I wouldn't encourage them all 
that much and its call TIS TISN'T, now in 
this game in loopy game. 
We represent the, where we are by nodes, 
and these two nodes are called tis and 
tisn't. 
And the blue player can move from tisn't 
to tis, and the red player can move from 
tis to tisn't. 
And, yes it is; no it isn't; yes it is; 
not it isn't; yes it it; no it isn't, 
yes, and this goes on for, you know as 
long as they want to play, it's kind of 
fun. 
here's a more more adult game you can 
play that's, that's loopy or possibly 
loopy. 
It's called fair shares and varied pairs. 
So what we have is a bunch of beans, or 
counters, I'm using quarters in this case 
on the table in various heaps. 
Now what can happen is, is there are two 
kinds of moves. 
You can take a heap of quarters and 
divide it into say two heaps of equal 
size or maybe four heaps of equal size. 
But in any case you could take any group 
of, any heap of quarters and divide it up 
into any number of heaps as long as 
they're the same size. 
That's called the fair shares part. 
The varied pairs part is you can take two 
heaps, as long as they have a different 
number, and combine them into a single 
heap. 
Now because, we can combine heaps and 
separate heaps out. 
There's a possibility, a real possibility 
that the game loops on forever. 
However, this is a really fun game to 
play at, at parties. 
Try with almonds, or, or walnuts. 
Or if you're in the South, try with 
pecans or pecans. 
I never knew which way to say it. 
in any case and then of course the first 
player who can't move loses. 
And the losing position is all heaps of 
one. 
There you can't separate them all out. 
And you can't combine them because 
they're all equal. 
And so this is the losing position who 
ever gets who ever's. 
Presented with this position here looses 
because there's no possible moves. 
So here's little about loopy moves and 
we'll be back in a few minutes with a 
little bit about Sente Gote.
