>> So here what I want to do just is, is to show you what I think the answers are.

Â And we'll come back next time and, and do this in more detail based on what, what

Â feedback we get. A plus b.

Â Left going first. Lefts, best move going first is to remove

Â 2 of these to ignore these edges over here.

Â Remove 2 of these in which case left can now, force a win.

Â So left going first, left wins and the best opening move, the winning opening

Â move is to remove 2, 2 quarters from the nim heap of side 3.

Â C plus F, is a 0 gain, and, so if left moves first, left loses.

Â E plus F, left moves first, let's see. Left moves first, the only move is to cut

Â down the, the left move over here, now right has to move over here.

Â Now left has no moves so left move, loses on here.

Â Four is the more complicated one, which we'll probably take a look at, at some

Â point. But it turns out that this is also a zero

Â gain and it turns out that if left, whatever move left starts with Left loses.

Â So, there's, there's some hints, It tells you what to shoot for.

Â Try, try, try, see if you can get the same answers as we.

Â Note that not. We want, just, not, not just the answers.

Â You should be able to explain, why it is that either left wins or right wins.

Â So we'll see you all next week. Take care.
