Strategy during key events

What is your strategy during key event such as RBI policy, budget or quarterly results in Bank Nifty, Nifty or specific stocks ?

I have tried Long Strangle many times during such major events…but it worked only 1 out of 10 times…further during such events margins are reduced for BO, MIS orders…so now I just wait until such events are over and market becomes normal and starts regular trading…!!
