The example he put above is fine: :)
```
subscriptions : Model -> Sub Msg
subscriptions model =
if (gameIsNotFinished model && model.turn == AIToMove) then
Time.every second AIMove
else
Sub.none
```
Though if you want it in another function you can do that too (useful to
batch functionality together):
```
subAITick : Model -> Sub Msg
subAITick model =
if (gameIsNotFinished model && model.turn == AIToMove) then
Time.every second AIMove
else
Sub.none
subscriptions : Model -> Sub Msg
subscriptions model =
subAITick
```
Or if you have other subscriptions too, batching them together:
```
subscriptions : Model -> Sub Msg
subscriptions model =
Sub.batch
[ subAITick
; otherSubscriptionsHere
]
```
