lolzzzzz...
I guess I read sarcasm in your tone. Sorry. Nevertheless, that is why it is a good strategy. The underlying moves significantly against you, yet not much pain.
Anyway, Close it just as you opened it. Depending on your trading platform, enter a butterfly, but change the "action" of each leg...
SPY Oct 131 "sell to close"
SPY Oct 136 "buy to close"
SPY Oct 141 "sell to close".
You can do it as 1 order. Check your trading platform and play with it...just don't execute the order.
