[Chess Tony could benefit from. Anything to focus his mind on, to give his hands something to do. To divert his energy and attention enough to actually have a normal conversation for longer than a few handfuls of seconds. There's a reason he gets drunk, why he stays drunk so much at home. His tongue is looser while drunk, it allows him to slip more into social norms, to dull his mind just the slightest amount, so he can stop living in Tony Stark's world and speaking that fast-paced language all his own. A language no one other than his own computer spoke and understood.

And even then, JARVIS couldn't quite keep up.

But he could benefit from a chess game, especially one with Charles. The guy was smart, for someone devoted to only one discipline. A geneticist, sure, and not his own personal choice in studies, but there was nothing inherently wrong with them. Not the smart ones, at least. The ones that found that their focus branched into others, that biology wasn't the end all be all of breakthroughs.

Still, he leans forward slightly on his knees, eyeing Charles with a stubborn blankness to his face, just the slightest hint of curiosity in his eyes.]

I thought I smelled money on you. What was it, inheritance? [Surprisingly enough? After a small pause, Tony's actually... giving something up. Just a small thing. But it's still something from his past. From a vault usually locked up tighter than Fort Knox.] At parties, that's what I was supposed to be. Seen, not heard. The son they showed off who never opened his mouth, never knocked anything over. [He smirks] Didn't light the kitchen on fire during a benefit trying to make a stove cook faster.
