There are several ways on how one can take advantage. I have extensively covered this using Google and several other companies for the earnings announcement movements. You may check out on my blog at http://www.OptionPundit.net/
Two ways that I have experimented are Backspread and diagonal backspread. These trades are non-directional but you may choose to be long on the side you are confident of. This will makemoney as long as it moves and move big.
Few things one need to consider-
1) Stock price movement to justify the premiums and
2) IV crush. This will affect both the short and long legs of the backspread. And therefore when choosing the strike, you may want to simuate the risk/reward, account for40-50% IV crush on both side and then review what are the breakeven points and see if it makes money.
I have initiated a discussion on my blog. If you would like to stay in touch, feel free to browse the blog or register for alerts. I am surely planning to play with this baby.
