How do you roleplay as a character more intelligent than yourself?

I already have 18 intelligence, so this isn't a problem for me.

"Connery's portrayal of Bond owes much to stylistic tutelage from director Terence Young, polishing the actor while using his physical grace and presence for the action. Lois Maxwell, who played Miss Moneypenny, related that, "Terence took Sean under his wing. He took him to dinner, showed him how to walk, how to talk, even how to eat."[45] The tutoring was successful; Connery received thousands of fan letters a week, and the actor became one of the great male sex symbols of film.[28]"

Being intelligent is literally just putting the time in to learn.

You don't.

Ask for assistance and notes from your GM.

Depending on system and dm: Frequently ask, if your character knows whatever you want to do/know/etc... - and if necessary do the appropriate checks.

I've always wanted to do this, but I've heard a lot of GMs don't like it because it feels like your trying to trivialize encounters by asking for the answer.

Alternatively, you could make a thread on Veeky Forums every session and live-feed us the scenario, then use the hive-mind to come up with brilliant plans.
I mean, it's probably just a good way to get yourself killed, but hey, it'd probably be a spectacular death.

That's where the checks come in (at least with my GM). It's never a "does my character know the solution to [the riddle]?" - that will only get me a "probably, ask again". If I want to access my character's knowledge on something, I have to ask specific questions.

I guess it's up to the DM and his ability to handle the gap between player and character knowledge.

Pretty easily.
In any game I can think of, intelligence just means booksmarts, not stuff like wisdom or good decision making (well, it might help you figure out which decision is more likely to succeed, but not which ones are 'better'). You can play an intelligent character basically the same as anyone else, just ask the gm to let you know things your character would probably know and take time making decisions.
