I can tell you're lost here. 

So, first question: why are you not using the provided Move class? `lib/move.rb`

second, if you have some possible moves, it should look like

```
def possible_moves
  {strike: 50, block: 40, leg_sweep: 60}
end
```

Later, when you need to randomly pick one of those? A hash can turn into an array

```ruby
Hash[possible_moves.to_a.sample(1)]
```
