Selling a call spread/'bear spread with calls'/credit spread with calls.   
    
 Idea is that you hope both options expire worthless - you only buy the higher strike call to limit your losses in the event that you're wrong. You can expand the max profit *a bit* by picking a higher strike for the purchased call, but it would expand your max loss considerably more.

You make out better doing this rather than by buying a put? If I understand correctly, your profit is limited with this to the premium you collect by selling the call, whereas if you bought a put and the price movement is correct your profits are limitless (til the stock hits $0 anyway).
