There are a plethora of online casinos, obviously. I came across some today that offer multiplayer mode, which I really like, but I have yet to find one that offers multiplayer and surrender in the same game. Any one know of any?
This doesn't answer your question, since Yahoo uses play money. When I was a noob, I practiced counting cards on Yahoo. I would bet $1 when TC<=1, and $1000 when TC>1. Once someone banned from a table for doing this. That was the first heat I ever got :o)
