Trust me, they won't laugh. They'll do everything in their power to make you feel welcome in the game. They won't be doing this out of the goodness of their hearts, of course. By making you feel welcome and relaxed, they hope to win your money, just as you hope to win theirs. I don't blame you.
Most people view card room poker as a world of almost unspeakable depth and mystery.
I viewed it that way myself once, before I screwed up my courage and pulled out my money and gave the game a try. So join me here in JV's Poker Room. No money's at stake. No one's gonna laugh at you.
