A winning strategy for any variation of card game shares certain crucial elements. Poker is a game of odds, luck, and player interaction - and understanding those concepts is the key to a good game. Playing successfully does not always involve winning; you also need to know when to fold. No one wins every hand. Successful players just win more often than they lose, and they know how to limit losses. The same is true whether you're playing Texas Hold'em, Five Card Stud, Lowball Poker, or even Go Fish.
