I am not sure why @corpsporc is suggesting the 5.Ne5 move. The square is unprotected and I would be just giving away a piece. Unless there is some gambit that I do not see, it would seem like an unsound choice.
I think that going with @Roeczak's suggestion of castling is the best way to go. Once the King is safely tucked away, I can afford to be a bit more aggressive with other moves and not have to worry about going back to save the King.
Since I am assuming that @zrylam is playing a King's Indian defense, which I think is generally a more passive position to play, then it sort of puts the ball in my court to play a bit more aggressive. So I might as well play my safe moves now, and then try to, "let 'er rip".
Therefore:
5.O-O
0-0
I think you should safe your king before u start the attack
