There are tons and tons of ways to cheat in home games. Collusion, cold decking, 2nd dealing, bottom dealing, flashing, glimpsing, copping, using shiners, juice decks, stripper decks, sandwork, the list goes on and on and on. It really does pay to be well informed.
Just because a game is low stakes doesn't mean that it won't be hustled. Its a lot easier to hustle a loose game than to hustle one with a lot of fast company. Just something to think about.
