YES, STRATEGIC, Lelouch can work out a schedule or some shit of which casinos they hit up and when to allay suspicion OR maybe they find some way to finagle it so that the casino owners can somehow earn money back by betting on them??? That might get a little too, like, overtly cheat-y, though. Then again, casinos. That said, they could ABSOLUTELY compete in like, legitimate poker tournaments against one another (and other people) to build up hype for the casinos themselves, which would rake in revenue from like advertising in so on? So that could be a way to recoup losses, but it would also compromise their anonymity. (Lelouch can also maybe use chess odds to help but am trying to focus on ways they can do max coop, so.)
